🇭🇰Hong Kong: HKEX Listing and Dim Sum Bonds

Concept

The Hong Kong exchange is not one door but six parallel listing routes with market capitalisation thresholds running from HK$150 million to HK$20 billion, and the route determines both the cost of the deal and whether the founder still controls the company after it.

The direct answer for anyone deciding now. A profitable company goes through the Main Board profit test: profit of ≥HK$35 million in the most recent year and ≥HK$80 million in aggregate over three years, with market capitalisation ≥HK$500 million (thresholds in force since 1 January 2022). A large company without profit goes through the market cap / revenue test: revenue ≥HK$500 million and market capitalisation ≥HK$4 billion. Pre-revenue biotech goes through Chapter 18A at ≥HK$1.5 billion. Other pre-revenue technology goes through Chapter 18C: ≥HK$4 billion with revenue of at least HK$250 million, or ≥HK$8 billion without it (the reduced thresholds run from 1 September 2024 to 31 August 2027). A company already listed on NYSE, Nasdaq or the LSE goes through Chapter 19C: from HK$3 billion with five years of compliance, or from HK$6 billion with two.

The realistic all-in budget (estimate) runs from 8.2–12.4% of proceeds on an HK$800 million deal to 1.4–2.9% on an HK$12 billion deal. The cycle is around seven months from kick-off to listing, and four to six months for an A+H dual listing on the accelerated track. The debt alternative in the same city is a dim sum bond in offshore renminbi: three to six weeks and 25–50 basis points all-in.

What follows is the detail, and one warning that governs all of it: almost everything written about HKEX before 2026 is obsolete. The rules have been rewritten three times in thirteen months.

Three consecutive reforms — 4 August 2025 (public float and placing mechanics), 1 January 2026 (ongoing float), 24 July 2026 (Competitiveness Review) — moved the balance toward the issuer. The flat "25% public float" rule is gone: above HK$30 billion of market capitalisation, 10% is enough. The WVR threshold for founder super-voting shares was halved, and the minimum stake a WVR beneficiary must hold fell from 10% to 5% of the economic interest in the issuer, and only where that interest is at least HK$4 billion. Non-public filing is open to every applicant, and the life of an application has doubled to 12 months. Any guide quoting "25%", "HK$40 billion" and "six months" is describing a regime that no longer exists.

The history of the exchange: from the 1891 brokers' association to HKEX

The Hong Kong exchange is an institution that grew out of a brokers' association founded in 1891, passed through a period of four competing venues, the merger of 1986, the crash of 1987 and the demutualisation of 2000, and is today Hong Kong Exchanges and Clearing Limited — a public company traded on its own market.

Dates and wording of the milestones follow HKEX Milestones and SFC, "Our role"; the events of 1969–1987, including the parameters of the crash and the Ronald Li criminal case, follow published accounts of the Hong Kong market's financial history.

Why there came to be four exchanges is a question of access, not technology. Ronald Li tried to buy a seat on the "British" Hong Kong Stock Exchange in 1969 and was refused; the exchange itself maintained listing conditions that cut off mid-sized Hong Kong companies at the height of the industrial boom of the 1960s. The Far East Exchange answered with a set of institutional innovations, each of them aimed at the class barrier: trading in Cantonese instead of English, women admitted as members and floor traders (the first such case among Commonwealth exchanges), several traders on the floor at once, and a glass public gallery through which outsiders could watch quotes. Far East overtook the old exchange on turnover and membership within a few years, and Kam Ngan and Kowloon appeared as imitators. The 1986 merger was not a technical consolidation of venues but the closing of a fault line that four exchanges had institutionalised for seventeen years.

The 1987 crash produced the modern supervisory regime. Closing the market for four days did not stop the fall, it postponed it: when trading resumed the index lost roughly another third. The futures default showed that the guarantee fund covered one four-hundredth of its own obligations. The Davison report set out the construction still in force: a regulator outside the civil service, staffed by professionals and funded by the market itself — and the SFC appeared a year later. The criminal case against the first chairman of the unified exchange settled the question of whether access to the market could remain in the hands of a private club.

The LME tail is still attached. After the nickel trades were cancelled on 8 March 2022, claims by Elliott Management (US$456 million) and Jane Street (US$15.3 million) were dismissed by the High Court in November 2023 and appealed, and in March 2025 the UK's FCA fined the LME £9.2 million for failing to prevent extreme volatility. HKEX's single large foreign acquisition remains its only channel of regulatory risk outside Hong Kong; the failed LSEG bid of 2019 did not widen that perimeter.

Waves of Chinese issuers: H shares, state banks, the exodus to the US and the return

Mainland issuers arrived in Hong Kong in four distinguishable waves, and each had its own legal construction — from the H shares of 1993 to the A+H dual listings of 2025–2026.

The chronology follows HKEX Milestones; HKEX annual market statistics 2025 (PDF); HKEX consultation paper, March 2026 (PDF).

H shares versus red chips is a distinction of place of incorporation, not of owner. An H share is paper in a company registered under PRC law; its regime is codified in Chapter 19A of the Main Board Listing Rules ("PRC Issuers") and includes constitutional requirements aligned with mainland Company Law, a special method of calculating market capitalisation (non-tradable domestic shares are valued at the average closing price of the H shares over the five preceding trading days) and mandatory online publication of documents. A red chip is an offshore holding company under mainland state control, and the ordinary rules for overseas issuers apply to it. The practical consequence shows up in the holder's pocket: a dividend on an H share passes through Chinese withholding tax, a dividend from a Hong Kong company does not. In current HKEX statistics the distinction is coarsened into the pair "H-Share Companies" and "Non H-Share Companies", which lumps red chips and mainland private enterprises into one bucket; a separate P-chips category was still being broken out in the 2019 statistics.

The cost of refusing WVR was calculated by the exchange itself. In 2013 Alibaba could not list in Hong Kong because of its "partnership" structure — a de facto mechanism of unequal voting rights — and went to the NYSE, where on 18 September 2014 it raised US$25 billion. The attempt to legalise WVR in 2015 was not stopped by the exchange: on 19 June 2015 SEHK published its conclusions on the concept paper, on 25 June 2015 the SFC issued a statement objecting to the construction, and on 5 October 2015 the Listing Committee announced that "in light of the SFC's statement" the project would not be taken forward. HKEX presented itself with the bill eleven years later, in the consultation paper of March 2026: 81 companies and US$38.8 billion gone to the US over a decade.

The A+H wave was triggered not by a rule change but by a decision about the queue. This is the key fact that usually goes missing. On 18 October 2024 the SFC and HKEX published a joint statement on an Enhanced Application Timeframe: on the standard track each regulator issues its conclusion within no more than 40 business days after a maximum of two rounds of comments, while for already-listed A-share companies with an expected market capitalisation of ≥HK$10 billion and confirmation from legal advisers of compliance with mainland law over two full financial years there is an accelerated track: one round of comments and 30 business days per regulator (HKEX, 18 October 2024).

The numbers then speak for themselves: 2024 — 71 listings and HK$87.5 billion; 2025 — 119 and HK$285.8 billion; first half of 2026 — 87 listings and HK$212.4 billion. Changes to the Listing Rules themselves — public float, pricing mechanics, the Competitiveness Review — came after the flow, not ahead of it. Extending the life of an application from 6 to 12 months in August 2026 is queue management for a backlog of 400–600 applications, not liberalisation.

The evolution of the Listing Rules: what was and what is

The HKEX Listing Rules have been rewritten by ten major reforms in a quarter of a century, and each has a measurable result that either confirmed the intent or refuted it.

The rule history follows HKEX GEM consultation paper, September 2023 (PDF); HKEX, 24 April 2018 on the new chapters; HKEX, 26 July 2019 on backdoor listings; HKEX, 17 December 2021 on the SPAC regime; HKEX, 24 March 2023 on Chapter 18C; HKEX consultation paper, March 2026 (PDF).

What the 2018 reform delivered in money is not what was written about it. The public narrative reduced it to super-voting rights for technology companies. The actual structure of the effect at the end of 2025 is different: WVR issuers number 31 — 1.2% of the 2,686 listed companies — but they raised HK$418 billion, 22.8% of all IPO money, and hold 14.7% of market capitalisation. Biotech delivered 83 companies and HK$133 billion; the number of healthcare listings grew 147% against the end of 2017, and the sector's market capitalisation rose from HK$1.1 trillion to HK$4.1 trillion, putting Hong Kong second in the world behind the US for biotech listings. Secondary listings account for 16.3% of the money raised under the new chapters. The remaining 65.7% sits in "other". In aggregate, new economy names accounted for 48.2% of market capitalisation and 59.4% of turnover at the end of 2025, against 14.6% and 21.6% for IT before 2017.

The exchange diagnosed its own error in 2026. Of the nearly 300 Greater China issuers that listed in the US after the 2018 reform and raised US$40.0 billion there, 223 would not have met the financial criteria of the Hong Kong rules at all — they accounted for US$15.8 billion, or 39.5% of the money. Liberalising WVR therefore missed the target for three quarters of the companies that left: what kept them out was not the voting structure but the admission thresholds. Hence the direct logic of the 24 July 2026 reform — thresholds halved across every branch. At the time of the consultation more than 400 Greater China issuers with a combined market capitalisation of US$1.54 trillion remained listed in the US, of which 377 companies with HK$2.78 trillion of market capitalisation have no Hong Kong listing — and that is the stated target of the reform.

Map of HKEX routes: the threshold matrix

A listing route is a set of alternative qualification tests under Chapter 8 of the Listing Rules plus the special Chapters 18A, 18C, 19C and 18B, and the issuer picks between them rather than the exchange picking for it.

Financial requirements and company history

Shareholder conditions and company types

The thresholds follow Main Board Rule 8.05, GEM Rule 11.12A, Rule 18C.03 with the SFC and HKEX joint announcement of 23 August 2024 on the temporary 18C and de-SPAC modifications, the HKEX announcement of 17 December 2021 on the SPAC regime, and Rules 8A.06 and 19C.05 as amended by the HKEX announcement of 24 July 2026.

Main Board: what the exchange actually tests

The Main Board is the baseline Chapter 8 route with three alternative financial tests, and passing any one of them is enough.

The thresholds are an entry filter, not the substance of the review. Applications are not turned away for missing profit by HK$5 million; they are turned away on three other grounds. The first is business sustainability: the exchange tests whether track-record revenue was manufactured by one-off transactions, related parties or customer concentration that will fall apart after listing. The second is continuity of ownership and management: three years of continuous management and the most recent audited year of continuous ownership. Since 24 July 2026 that rule has been codified more softly — a change of controlling shareholder within the track record period is acceptable provided there was no material change of management influence in the last audited year before listing. The third is suitability as a free-standing discretion: a business model that depends on a single regulator's permission, litigation and tax tails, opaque pre-IPO restructuring.

Accounts are accepted under HKFRS, IFRS or, for PRC issuers, CAS; since 24 July 2026 US GAAP is permitted more widely, for subsidiaries of US-listed groups and companies with substantial US operations, subject to reconciliation and disclosure of differences. The board needs at least three independent non-executive directors making up at least one third of its members, plus a mandatory audit committee and remuneration committee. The latest reporting period must be no more than six months old at the date of the listing document, which is exactly why a preparation process that drags on triggers a re-audit.

Jurisdiction of incorporation: since 1 January 2022 HKEX no longer distinguishes recognised from acceptable jurisdictions; every issuer, including companies incorporated in Hong Kong, the PRC, Cayman and Bermuda, must meet the 14 core shareholder protection standards in Appendix A1, and the earlier country guides have been archived (HKEX, listing of overseas companies; HKEX, archived country guides). The standard construction for a founder who is not a PRC resident is a Cayman or BVI holding company; the choice of vehicle is covered in the material on holding structures.

Chapter 18A and 18C: companies with no revenue

Chapters 18A and 18C are two special routes for companies that pass none of the Chapter 8 financial tests, where instead of profit the exchange assesses R&D, product stage and the presence of professional investors.

18A (biotech) is the more road-tested of the two. Market capitalisation of HK$1.5 billion, working capital covering 125% of the next 12 months' costs, a core product past concept stage, and at least one Sophisticated Investor that does not exit at the IPO. The route works: 2025 saw 14 pre-revenue biotech listings against 4 in 2024 (KPMG, 10 December 2025), and a cumulative 88 biotech and specialist technology companies had listed in Hong Kong under the two chapters since 2018 (count as at 22 December 2025) (HKEX, 22 December 2025).

18C (specialist technology) launched on 31 March 2023 and was written off as dead for three years: eight listings in total across 2023–2025. The break came in 2026. By 31 March 2026, 14 companies had listed under Chapter 18C raising HK$28.4 billion (HKEX Insight, "18C, Explained"), and the first half of 2026 alone produced 13 Chapter 18C listings — more than the previous three years combined and 14% of all funds raised on the exchange (KPMG, June 2026). Three causes: the temporary threshold cut to HK$4 billion / HK$8 billion from 1 September 2024, the launch of the TECH channel (Technology Enterprises Channel) on 6 May 2025 with a dedicated support team and a presumption that applicants meet the innovative company requirements, and an accumulated pipeline of Chinese hardware and AI.

One practical point to keep in the calendar: the reduced 18C thresholds expire on 31 August 2027. Companies valued between HK$4 billion and HK$6 billion face a hard filing deadline. Chapter 18C also requires a minimum aggregate investment from Sophisticated Independent Investors, measured as a share of the issued share capital at listing and keyed to market capitalisation (commercial / pre-commercial company): below HK$15 billion, 20%/25%; HK$15–30 billion, 15%/20%; HK$30 billion and above, 10%/15% (HKEX, Chapter 18C consultation conclusions, March 2023, Table 8 (PDF)). The 18C lock-ups for controlling shareholders and key persons are set out in the section on public float and lock-up.

GEM and SPAC: two routes that do not work

GEM and SPAC are formally live HKEX routes, both reformed and both failing to deliver the deal flow that was expected of them.

GEM was killed by the exchange's own reform: on 15 December 2017 HKEX abolished the streamlined transfer to the Main Board (effective 15 February 2018), raised the financial thresholds and extended the lock-up, and in September 2023 it named that as one of the three causes of the board's collapse.

After the restorative reform of 1 January 2024 it became markedly friendlier: quarterly reporting abolished, the annual report deadline extended from three to four months, the controlling shareholder lock-up cut from 24 to 12 months, the compliance officer role made optional. An alternative R&D test was introduced: market capitalisation ≥HK$250 million, revenue ≥HK$100 million over two years with growth, and R&D ≥HK$30 million running at no less than 15% of opex in each year. A streamlined transfer to the Main Board was opened as well: three full years on GEM, a clean compliance record and average daily turnover of ≥HK$50,000 on at least half the trading days in a 250-day reference period — with no sponsor and no prospectus.

None of this restored deal flow: on 24 July 2026 HKEX announced a second phase of consultations with GEM reform carved out as a separate item.

SPAC (since 1 January 2022) requires gross proceeds of ≥HK$1 billion at a share price of ≥HK$10, a minimum of 75 professional investors of whom 20 institutional investors hold 75% of the shares placed, and a promoter with an SFC Type 6 or Type 9 licence holding at least 10% of the promoter shares. De-SPAC: announcement within 24 months, completion within 36 months of listing. An independent PIPE investment is mandatory on a sliding scale from 25% for a deal below HK$2 billion to 7.5% at ≥HK$7 billion, and since 1 September 2024 it is the lesser of that percentage and HK$500 million (Charltons on the SPAC regime).

Why it never took off. The Hong Kong SPAC was designed from the start as the opposite of the American one: before de-SPAC the security is closed to retail, so there is none of the speculative demand that created promoter economics in the US. The mandatory PIPE effectively hands valuation validation to an institutional investor, meaning the promoter has to bring in the same investor who would have subscribed to an ordinary IPO — but with two layers of cost and a hard time limit. Finally, the 2022–2024 window coincided with the worst period the Hong Kong market has seen, and by the time it turned in 2025–2026 an ordinary IPO had become faster and cheaper than a SPAC. The upshot: SPAC reform has also been pushed into the second phase of the 2026 consultations.

Secondary listing, dual primary and weighted voting rights

Chapter 19C is the route for a company already listed on a Qualifying Exchange (NYSE, Nasdaq, the LSE Main Market), letting it enter Hong Kong without the full Chapter 8 cycle.

The reform of 24 July 2026 cut the thresholds by roughly half across every branch: Criteria B without WVR fell from HK$10 billion to HK$6 billion at two years of compliance; with WVR, Test A fell from HK$40 billion to HK$20 billion, and Test B from HK$10 billion plus HK$1 billion of revenue to HK$6 billion plus HK$600 million. Guidance on converting a secondary listing into a primary one was simplified at the same time (Morgan Lewis, August 2026).

For a founder, the WVR block matters more. The cap on the voting ratio stays at 10:1, but rises to 20:1 where market capitalisation is ≥HK$40 billion. The minimum stake for a WVR beneficiary drops from 10% to 5% of the economic interest in the issuer, and only where that interest is ≥HK$4 billion — the rule measures a share of the issuer's capital, not a share of the offer. The innovation test has been rewritten into two routes: Route A is technological (substantial R&D, successful IP monetisation, or a market capitalisation disproportionate to tangible assets), Route B runs on the business model (a new model, revenue CAGR ≥30%, a notable industry position, profitability metrics). Route B is genuinely new in that it opens super-voting rights to non-technology companies. Chapter 18A and 18C applicants are presumed to satisfy Route A.

The bedrock Chapter 8A safeguards survive intact: a WVR beneficiary must be an individual who is a director at listing and retains an executive role; the rights lapse on death, departure from the board, incapacity or failure to meet the director requirements; WVR shares cannot be transferred to third parties; and on reserved matters (appointment and removal of independent non-executive directors, voluntary winding-up, changes to the constitutional documents, change of auditor, variation of class rights) strict one-share-one-vote applies. The ticker carries a "W" suffix. At the end of 2025 there were only 31 WVR issuers — 1.2% of the 2,686 companies listed on the exchange (21 primary and ten secondary listings) — though they accounted for 14.7% of market capitalisation (HKEX consultation paper, March 2026, PDF).

What changed in 2025–⁠2026: a dated summary

The regulatory delta is the set of changes to the Listing Rules and adjacent regimes that took effect after August 2025 and are not reflected in most available guides.

The dated summary follows HKEX Consultation Conclusions cp202412cc (PDF), August 2025; Latham & Watkins, August 2025; Charltons on the new ongoing float requirements from 1 January 2026; HKEX, 17 December 2025; HKEX, 21 August 2026; HKEX Consultation Paper, March 2026 (PDF); KPMG on the stamp duty cut of 17 November 2023.

The supervisory architecture: HKEX, the SFC and dual filing

A Hong Kong listing is regulated by two bodies: the exchange applies the Listing Rules as front-line regulator, while the SFC supervises the exchange, approves every change to the Rules and, through the dual filing regime, can stop an individual application.

The division of functions. The SFC is an independent statutory body created in 1989; its investigative and disciplinary powers derive from the Securities and Futures Ordinance, and it is funded mainly by transaction levies and licensing fees rather than by the budget. SEHK runs day-to-day enforcement of the Listing Rules; the SFC supervises the exchange's performance of its listing functions, conducts periodic audits and approves any amendment to the Listing Rules, as recorded in a memorandum of understanding (SFC, regulation of corporates). Inside the HKEX group the listing function sits in a separate loop: the board's Listing Operation Governance Committee includes members ex officio by virtue of their positions in the Listing Committee structure. The first instance for listing and disciplinary decisions is the Listing Committee, the appellate body is the Listing Review Committee, whose decisions have been published by year since 2019.

Dual filing is the real valve. The regime has operated since 1 April 2003 under the Securities and Futures (Stock Market Listing) Rules: applicants and listed companies file documents with the SFC through the exchange, which gives the SFC an independent basis for pursuing the issue of false or misleading corporate information. Two practical instruments follow. Section 6(2) SMLR allows the SFC to object to a listing application. Section 6(3)(b) allows it, where it does not object, to impose conditions on approval which the applicant must disclose in the prospectus; the publicly known examples are United Company Rusal Limited and Better Home Group Holdings. Since 2017 the SFC has put its questions directly to the applicant, bypassing the exchange (SFC, dual filing).

The Takeovers Code. The Codes on Takeovers and Mergers and Share Buy-backs (current edition 29 September 2023) do not have the force of law: they are described expressly as a consensus among market participants and the SFC on standards of commercial conduct. Three bodies apply them: the Executive (day-to-day work), the Takeovers and Mergers Panel (rulings and statements) and the Takeovers Appeal Committee. The three core principles are equal treatment of shareholders, timely and adequate disclosure, and a fair and informed market. The absence of statutory status is compensated by one sanction, but an effective one — the cold shoulder order, denial of access to the market through professional intermediaries; orders in force are published in a register. The scale of the work: 395 transactions and applications handled in the 2024/25 financial year (SFC, takeovers and mergers).

Exchange enforcement in numbers. For 2025: 104 cases (91 Main Board, 13 GEM), 45 investigations commenced, 29 disciplinary actions started and 27 completed, 100 referrals to other authorities, 11 public censures of issuers and 28 of individuals, 38 director unsuitability statements. The average investigation in 2023 ran 12.4 months. For the first half of 2026: 85 cases, 15 investigations, 40 censures of individuals (HKEX enforcement statistics).

Delisting: routine that is not counted in public. Since Rule 6.01A was introduced the exchange cancels a listing after 18 months of continuous suspension on the Main Board and 12 months on GEM under Rule 9.14A (HKEX, conclusions of the delisting consultation, 25 May 2018). But neither the enforcement statistics, which count even director unsuitability statements in detail, nor the annual market statistics contain a "delistings" line. The figure is derived from the difference between new listings and the net change in the issuer count.

This is a calculation, not a published metric: the base is HKEX annual market statistics (new listings and the number of listed companies at year end), and the subtraction gives departures accurate to within transfers between boards. The order of magnitude is 50–65 issuers a year, about 2–2.5% of the list, which is radically different from the stagnant Practice Note 17 model. Examples of 2026 cancellations from the exchange's regulatory announcements: Greentech Technology, Renco Holdings, Boill Healthcare, Paladin, Greater China Financial Holdings, Yu Tak International.

Deal participants and sponsor liability

The sponsor is the only IPO participant with its own licensing regime and personal responsibility for the prospectus, and since 2013 it, rather than the issuer, has been the first target of SFC enforcement.

Legal status. A sponsor must hold an SFC Type 6 licence (advising on corporate finance) with a specific permission for sponsor work; the applicant must appoint a sponsor under Rule 3A.02, and an A1 filing cannot be made earlier than two months after the date of formal appointment (Rule 3A.02B), or after the appointment of the last sponsor where there is more than one. At least one sponsor must be independent. Since 5 August 2022 the "sponsor coupling" rule applies: before accepting a mandate the sponsor must either itself be independent and simultaneously appointed as an Overall Coordinator, or obtain written confirmation from the issuer that an independent sponsor has been appointed as OC. The core duties are listed in §17.2 of the Code of Conduct: advising the applicant, reasonable due diligence before the A1 filing, ensuring truthful and complete disclosure, dealing with regulators honestly, record-keeping, adequate resources and supervision, managing the public offer as a whole, and preventing the passing of undisclosed information to analysts (SFC Code of Conduct, edition of 2 January 2026, PDF).

The 2013 reform rewrote the liability regime: all reasonable due diligence must be complete before the A1 filing, the Application Proof must be "substantially complete" or the application is returned, and the sponsor is named publicly when it is. The position that prospectus liability extends to the sponsor as a person who authorised the issue of the prospectus, under ss. 40 and 40A of the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32), is the common understanding in practice, but it is not stated in those terms in the available primary documents, so it is given here as industry understanding rather than as a rule with a precise citation.

Sanctions against sponsors are not an abstraction. The SFC's public register of disciplinary actions gives an unbroken run since 2014.

The source is the SFC press release register (for example, the UBS case, 14 March 2019, refNo 19PR19). A single day, 14 March 2019, cost four global banks HK$786.7 million. The UBS cases concerned China Forestry (IPO 2009) and Tianhe Chemicals; on China Forestry the SFC found that the sponsor had carried out no site visit to the forestry assets after its appointment and could produce no records of the 2008 inspections. Changjiang was fined over six listing mandates filed between September 2015 and December 2017.

The thematic strike of January 2026 amounts to rationing mandates. As new applications handled by the SFC rose from 250 in 2024 to 612 in 2025, the bottleneck stopped being the exchange and became the sponsors' capacity to do due diligence. The SFC circular of 30 January 2026 records "serious deficiencies" in the preparation of listing documents and introduces concrete measures: 13 sponsors received a joint SFC/SEHK letter in December 2025, and they and sponsors with stretched resources were given three months for a comprehensive internal review; all sponsors must report the ratio of active mandates to appointed sponsor principals; a sponsor with one principal running six or more active transactions must submit a remediation and resourcing plan; vetting of 16 applications was suspended as at 31 December 2025; and the SFC announced a thematic inspection and the possibility of directly capping the number of mandates at firms that fail to remediate. The formulation used by SFC chief executive Julia Leung: the gatekeeper role may have been undermined "in a greedy pursuit of deal volume".

The practical consequence for an issuer choosing a sponsor in 2026: the name of the bank no longer guarantees speed. The question to ask is not about reputation but about the workload of the specific sponsor principal who will run the deal — at six or more active mandates per principal the firm is under an SFC-mandated remediation plan and its applications are at risk of having vetting suspended. Changing sponsor resets the application: adding or removing any sponsor requires a fresh A1 with a fresh initial listing fee, and since 21 August 2026 a change of sponsor automatically lapses the filed application.

The rest of the team. The reporting accountant is regulated by Chapter 4 of the Listing Rules: it must be independent to the same extent as an auditor under the Companies Ordinance, and preparing an accountants' report is a PIE Engagement, so the firm must be a Registered PIE Auditor; the report covers the three most recent financial years.

The issuer's and the underwriters' legal counsel have no direct licensing regime under the Listing Rules — they are disciplined by disclosure: since 24 July 2026, when an application is returned, the exchange publishes the identities and roles of all professional parties that prepared the materials, together with the reasons for the return. The share registrar must maintain the register of members in Hong Kong (Rule 8.16), and the receiving bank is called the Designated EIPO Bank in the FINI architecture.

The syndicate is regulated by §21 of the Code of Conduct, introduced on 5 November 2021 and effective from 5 August 2022: the Overall Coordinator coordinates bookbuilding, pricing and allocation, the Sponsor-OC is appointed at the same time as the sponsor and no later than two months before filing, and the other syndicate members take the status of Capital Market Intermediaries.

Public float, free float and lock-⁠up

Public float is the proportion of shares in public hands required at listing and on an ongoing basis; free float is the narrower figure that excludes any shares subject to disposal restrictions.

The scale at listing, in force since 4 August 2025: market capitalisation ≤HK$6 billion — 25%; HK$6–30 billion — the greater of 15% or shares worth HK$1.5 billion; above HK$30 billion — the greater of 10% or HK$4.5 billion. For A+H issuers, H shares in public hands must be at least 10% of the H share class or HK$3 billion of market value. A separate initial free float requirement was added: at least 10% of the class with a value of ≥HK$50 million, or ≥HK$600 million outright; 5% for A+H. The key consequence: cornerstone investors' shares and the controlling shareholder's locked-up shares do not count toward free float, so you cannot sell half the issue to a cornerstone pool and still expect to clear the minimum free float.

The controlling shareholder lock-up under Rule 10.07: an absolute bar on disposals for the first six months from the listing date, then six months in which disposals are permitted but not to the point of losing controlling shareholder status. Twelve months in total, and the same for GEM since 1 January 2024. Chapter 18C adds to that: 12 months for commercial companies and 24 months for pre-commercial companies, key persons included. Cornerstone investors are locked up for six months; the proposal to allow staggered release was rejected in the 2025 consultation conclusions. The general mechanics of lock-up, including the structure of carve-outs and organised secondary sales, are covered separately in the materials on lock-up and secondary share transactions.

The IPO calendar and cornerstone investors

The listing calendar is a cycle of roughly 210 days from kick-off to listing, split into four phases with fixed regulatory windows inside them.

The timeline follows A&O Shearman, Indicative Timeline for an IPO in Hong Kong. Realistically (estimate): an A+H on the accelerated track takes four to six months, a Chapter 18C listing from a standing start nine to fifteen. Where CSRC approval is needed, the Hong Kong accelerated track runs into the mainland regulator's own timetable.

The sponsor must be appointed no later than two months before the A1 filing and must hold an SFC Type 6 licence. The full team: sponsor, issuer's legal counsel, underwriters' legal counsel, reporting accountant, valuer (a property valuer where real estate is material, an independent business valuer for 18A and 18C), industry consultant (de facto mandatory for 18C), tax adviser, receiving bank, share registrar, IR agency, financial printer, D&O insurer. An A+H adds PRC counsel and a CSRC filing. The requirements around audit in Hong Kong are a separate layer of preparation, and usually the one that dictates when the calendar really starts.

Cornerstone investors sign up before the roadshow, take a fixed amount at the offer price (they take no part in price discovery), are named in the prospectus, receive a guaranteed allocation and accept a six-month lock-up. The typical share is 20–50% of the issue, closer to the upper bound in the large 2025–2026 deals (a market estimate; on the exchange's own data, the cornerstone tranche averaged 31% of the offer for issuers over 2020–2024).

The ceiling, by contrast, is not an estimate but arithmetic from the documented HKEX requirement that at least 40% of the offer go to the bookbuilding tranche (HKEX, Consultation Conclusions cp202412cc, August 2025, PDF, §16): with a minimum public tranche of 5% under Mechanism A, 55% of the issue is left for cornerstones, and with 10% under Mechanism B, 50%.

In Shein's listing on 1 September 2026 the cornerstone pool was about US$383 million — up to 22.5% of proceeds — with Boyu Capital, Tiger Global, General Atlantic, Tencent, Greenwoods, Taikang Life and UBS (SCMP, 24 August 2026). The 2025–2026 trend is the return of international long-only money after a four-year absence: BlackRock, Temasek, Qatar Investment Authority, Fidelity International (SCMP on the cornerstone comeback).

Placing mechanics: FINI, clawback and the application queue

The mechanics of a Hong Kong placing are a chain of three things: the FINI settlement platform, the rules for reallocating between the retail and institutional tranches, and the application queue, which since 2025 has become the main constraint on speed.

FINI changed the economics of subscribing. The Fast Interface for New Issuance is an HKSCC platform that went live in November 2023 after the concept paper "Modernising Hong Kong's IPO Settlement Process" of 16 November 2020. It is mandatory: settlement on the old T+5 cycle is no longer supported for migrated listing types. The new cycle: T is the pricing date and T+2 is the first day of trading; the offer is initiated from the post-hearing letter, and the filing deadline is T−5. The platform replaced an exchange of letters and paper forms between sponsors, advisers, coordinators, distributors and both regulators for placee vetting and allocation approval. HKSCC charges a stock admission fee of HK$50,000 to HK$600,000 on a scale keyed to deal size, and an EIPO processing fee capped at 0.3% of gross proceeds (FINI Information Pack, HKEX, PDF). The historical starting point was the Alibaba offer of November 2019: the first fully electronic public offer in Hong Kong, which started at T+4 rather than the traditional T+5 minimum.

The key FINI innovation that almost nobody writes about is compressed pre-funding. The cash requirement for a CCASS participant is calculated as the lesser of the full value of its order book and PO_MAX — the maximum the issuer could physically allocate to the public tranche if the full clawback and all discretionary reallocations were triggered. PO_MAX is computed in advance and displayed in the system. The practical effect: submitting an application into a thousand-times oversubscription has become almost free in terms of frozen capital.

Clawback: history and current construction. A minimum public tranche was codified in the Listing Rules in 1998 following an SFC consultation on offer mechanisms; the justification was retail's share of cash market turnover, which the 1997 survey of exchange participants' transactions put at 53%. By March 2023 that share had fallen to 12%, and the whole construction lost its original basis. Until 4 August 2025 the Practice Note 18 scale applied (10% / 30% / 40% / 50%), while large deals routinely obtained a standard waiver of 5% / 7.5% / 10% / 20%, and Chapter 18C companies had a separate 5% / 10% / 20% scale that they must still apply today. Mechanisms A and B are set out above. The exchange deliberately did not raise the oversubscription trigger points, explaining expressly that oversubscription multiples inflate with macro conditions and brokers' margin practice — in other words the regulator itself treats record multiples as an artefact of infrastructure and leverage rather than demand.

Related placing constraints: ring-fencing of the bookbuilding tranche at no less than 40% of the shares initially offered in every IPO (the consultation had proposed 50%); an Allocation Cap setting an effective reallocation ceiling of 10% under Mechanism A and 15% under Mechanism B; and above all that, an indirect cornerstone ceiling around 50–55% of the issue. A direct cap on cornerstones was considered and rejected. The factual base for the estimate: among 2020–2024 issuers that would have failed the proposed free float test, the cornerstone tranche averaged 31% of the offer size. The exchange expects the over-allotment option (greenshoe) to stay within 15% of the initial size; the same ceiling applies to the offer size adjustment option, which may not be described as an over-allotment option. Stabilisation is governed by the Securities and Futures (Price Stabilizing) Rules and is not permitted for offerings below HK$100 million.

The application queue is the new reality of 2025–2026. The exchange's application processing statistics show what happened to the market.

The table follows HKEX 2025 annual results, 26 February 2026 (PDF), IPO Processing section. Two caveats for reading the table. First, the exchange publishes an aggregate line, "others (lapsed, rejected, returned or withdrawn)" — 99 applications in 2025 and 59 in 2024 — whereas the separately disclosed lapsed, returned and rejected figures add to 96 and 57; the difference of three and of two is withdrawn applications, for which the reporting carries no line of its own. Second, there is no "active applications at 31 December" line in the reporting either: it is the sum of two disclosed lines, "under processing" and "approved by the Listing Committee, pending listing", and is therefore a calculated figure. From the SFC side the figure is even starker: 603 new listing applications in the 2025/26 financial year, up 282%, including 108 from pre-profit biotech and 72 from specialist technology companies (SFC Annual Report 2025-26, PDF).

The way to read that table: formal return of an application is barely used, and there are no rejections at all. Discipline is delivered by silent expiry — the A1 lapsing, vetting being suspended, and letters raising material comments. The public pillory of the Return Mechanism functions as a threat rather than a tool, and the July 2026 reform sharpened exactly its reputational component: on a return, the identities and roles of all professional parties and the reasons for the return are published.

Since 24 July 2026 the public pipeline statistics have stopped being comparable. Previously the Application Proof was published at filing, and "345 active applications at 31 December 2025" was an observable market figure. Now that non-public filing has been extended to every applicant, an A1 need not be disclosed until the post-hearing information pack. Some consultation respondents warned expressly that this compresses the due diligence window for investors and analysts. Any time series on the application queue should be broken at July 2026 rather than compared across it.

The full IPO budget: what a listing actually costs

The cost of an IPO is the sum of exchange fees, professional fees and underwriting commission; the exchange fees are negligible within it, and the economics are decided by the other two.

Only the first line is public. The initial listing fee is paid up front at the A1 filing on a scale keyed to the value of the securities to be listed: HK$150,000 for an offering of ≤HK$100 million, HK$250,000 at HK$500 million, HK$300,000 at HK$750 million, HK$350,000 at HK$1 billion, HK$550,000 at HK$3 billion and HK$650,000 above HK$5 billion (the cap). The annual listing fee starts at HK$145,000 a year for a nominal value of ≤HK$200 million and rises on a scale (HKEX Main Board Fees Rules, PDF).

Everything else is undisclosed. Neither HKEX, nor the Big Four, nor the compilers of cross-border listing guides publish adviser fees. The ranges below are market estimates assembled from observed deal budgets; the spread within each line comes down to three factors: the complexity of the pre-IPO restructuring (number of jurisdictions, VIE structures, historical cleanliness of title), the volume of re-audit work (moving from a local standard to IFRS or HKFRS doubles the reporting accountant's budget), and whether the issuer is running a parallel mainland track with a CSRC filing.

The arithmetic reads one way only: professional costs are close to fixed, so the cost ratio falls in inverse proportion to deal size. Below HK$500 million of proceeds the costs eat a double-digit share, the offering stops making economic sense, and that — not any rule threshold — is the real minimum entry point for HKEX.

The other half of the equation is the collapse in underwriting commissions, which almost nobody writes about. The average base commission on Hong Kong IPOs in 2025 was 1.5% — the lowest since at least 2000, against a 25-year average of 2.3% and 2.4% across Asia-Pacific. For A-to-H deals the average base commission is 0.9% against 2.2% for ordinary IPOs; CATL paid a base commission of 0.2% plus a 0.6% incentive fee on proceeds of US$5.3 billion. The total fee pool nonetheless reached US$489 million in 2025, the highest since 2021: banks are earning on volume, not on rate (China Daily HK, 11 December 2025). The claim that "an IPO costs 5–7%, as in the US" is off by an order of magnitude for a large Hong Kong deal.

One budget line is regularly forgotten at the decision stage: the recurring cost of being public — annual listing fee, HKFRS audit, independent director fees, IR, D&O insurance, legal support for disclosure and connected transactions. The realistic order of magnitude is HK$8–20 million a year for a mid-sized company (market estimate), and since the reform of 31 January 2026 monthly float returns have been added to it.

Three prospectuses: how these costs appear in disclosure

Since 5 August 2022 the Code of Conduct has required disclosure of the split of underwriters' remuneration between its fixed and discretionary parts, so real numbers are available from prospectuses. Three deals cover the whole range of sizes.

The cost figures come from the prospectuses on hkexnews — CATL, Ingenic, Mech-Mind.

Three conclusions this table makes visible. First, the relative cost of an offering is non-linear — 0.93% against 6.6% across a thirteen-fold difference in size. Second, lawyers and auditors cost a small deal more in absolute money than they cost a mega-deal (HK$36.2 million against HK$24.4 million), because the volume of verification is set by the complexity of the group rather than by the size of the raise, and the sponsor fee does not scale at all. What makes a small Hong Kong IPO expensive is the fixed cost of compliance, not bank greed. Third, on mega-deals the underwriting commission has legally stopped being a commission: three quarters of CATL's underwriter remuneration was a payment the issuer is entitled not to make at all.

Scandals and failures: what the Hong Kong market is known for

The enforcement history of HKEX rests on a handful of cases, each of which changed the shape of the regime: a chairman of the exchange jailed for bribery, a 47% collapse in minutes, the largest default in Chinese real estate, and a US$34.5 billion offering halted two days before listing.

The regulatory record follows SFC Annual Report 2024-25 and 2025-26; SFC Enforcement Reporter, March 2026 (PDF). The circumstances of the Hanergy, Evergrande, Ant Group and Ronald Li cases follow predominantly the reporting of the business press; the regulatory actions in each are taken from SFC documents.

The toolkit road-tested on these cases: director unsuitability statements and disqualification (the exchange), a trading suspension directed through the SFC, civil proceedings for compensation and buy-back orders under ss. 213–214 SFO, asset freezes, cold shoulder orders under the Takeovers Code, and referrals to the ICAC and the police (100 referrals in 2025). Since 2024/25 the SFC has run its own AI model, the Market Scanning Detection Model, to identify higher-risk issuers early, and the SENSOR system for social media monitoring; in July 2025 the Charter 3.0 alliance with technology companies and telecom operators was launched. The scale of the background fraud on which this rests: the Hong Kong police recorded more than 44,000 fraud cases in 2024, a fourfold increase in five years.

HKEX statistics by year: 2015–⁠2026

The twelve-year run shows not steady growth but two collapses and two recoveries, with a sixfold amplitude in IPO volume between the 2023 trough and the 2020 peak.

New listings and IPO proceeds

Market size and global ranking

The table follows HKEX annual market statistics by year and HKEX Monthly Market Highlights. Discrepancies between publications exist and are not concealed: the 2024 figure on the 2024 page is 87,478, on the 2025 page 87,975; 2025 IPO proceeds are 285.8 billion in the statistical table and 286.9 billion in the press release. The global ranks for 2020–2023 are industry estimates: the exchange gives no rank of its own for those years. For 2024 there is no comparable rank: the exchange described itself as "one of the top four venues".

What this run shows and the headlines do not. A record IPO year in 2025 did not restore the market's peak capitalisation: HK$47,393 billion at the end of 2025 is still below HK$47,523 billion at the end of 2020, and August 2026 is below it too. Meanwhile average daily turnover rose from HK$129.5 billion in 2020 to HK$249.8 billion in 2025 and HK$282.5 billion over the first eight months of 2026. Over six years the market has grown radically in liquidity and not at all in value — it has become more tradable, not more expensive. The second fact in the same run: at the end of 2025 mainland issuers accounted for 1,552 companies (58% of the list), 79% of market capitalisation, 91% of equity turnover and 89% of funds raised. By composition the Hong Kong exchange has long been a Chinese venue in a foreign legal wrapper.

Liquidity and concentration: what the market looks like from inside

Liquidity in Hong Kong is extremely concentrated: the headline HK$249.8 billion of average daily turnover in 2025 is distributed such that three quarters of quoted securities do not reach even HK$10 million in a trading day.

The exchange publishes no such breakdown, so the figures below are computed from HKEX daily quotations for 3 September 2026 (Daily Quotations). Market totals for the day: turnover HK$199.4 billion, 3.84 million trades, 8,108 instruments traded. The sample is codes 1–3999 (shares, REITs, ETFs, leveraged products): 2,313 quoted securities with combined turnover of HK$147.25 billion, or 73.9% of the market; the other 26.1% comes from derivative warrants and CBBCs.

This is a calculated figure from a single trading day's snapshot, not statistics published by the exchange; it is reproducible from the daily quotations file cited. The leaders that day: Tracker Fund (2800) — HK$8.96 billion, CSOP HS Tech (3033) — HK$8.14 billion, Tencent — HK$7.60 billion, Alibaba-W — HK$7.56 billion. The practical conclusion for an issuer: getting listed does not by itself create liquidity, and a company outside the top 500 by turnover trades in shop-window mode. For a holder the conclusion is the mirror image and just as hard — a position in a security beyond the first few hundred is closed at a price set not by the market but by the seller's impatience.

The Southbound double-counting trap. HKEX publishes Southbound turnover as the sum of buys and sells, whereas total market turnover is counted one-sided. Naively dividing August's HK$107.3 billion of Southbound turnover by HK$253.4 billion of market turnover gives "42%" — a figure that circulates widely and is overstated by roughly a factor of two; the correct order of magnitude is about 21%. Any claim along the lines of "mainland money is almost half the Hong Kong market" is very likely built on exactly this error.

For context: Southbound average daily turnover in 2025 was HK$121.1 billion (Shanghai 75.2 plus Shenzhen 45.9), HK$129.2 billion in July 2026 and HK$107.3 billion in August. A retail versus institutional split of turnover is not available: the survey of exchange participants' transactions that produced those series is no longer published, and the only primary reference point is the 41% of 2020 turnover attributed to international participants.

Trading microstructure and index architecture

The Hong Kong order book works differently from the mainland's: there are no daily price limits, a targeted volatility control mechanism operates instead, and the board lot is set by the issuer.

Sessions. The trading day is divided into a pre-opening session (09:00–09:15 for order input within a ±15% band around the previous close, 09:15–09:20 with no cancellation, 09:20–09:22 random matching), a continuous session of 09:30–12:00 and 13:00–16:00 on price-time priority, and a closing auction from 16:00 to 16:10. The Closing Auction Session works like this: the reference price is the median of five nominal price snapshots taken from 15:59:00 at 15-second intervals, the order input band is ±5% around it, then narrowed to the best bid and ask, with a random close. The current CAS launched on 25 July 2016 and was extended to all equities and funds on 8 October 2019 (HKEX, trading mechanism).

The VCM instead of price limits. The Volatility Control Mechanism triggers when the price moves away from its level five minutes earlier by ±10% for large HSCI constituents, ±15% for mid caps, ±20% for small caps, ±30% for SPAC shares and ±5–10% for leveraged and inverse ETPs. A five-minute cooling-off period follows, during which trading does not stop — it continues inside the band. Monitoring is switched off for the first 15 minutes after the open and the last 20 minutes of the day session; the cap on the number of triggers per session was removed on 29 March 2021. The mechanism launched on 22 August 2016 across 81 securities and was extended on 11 May 2020.

Board lots and ticks. There is no single board lot standard — the issuer sets it, which is why lots run from 100 to 5,000 shares and beyond; odd lots trade in a separate market outside automatic matching, usually at a discount. The tick grid went through two phases of reform after the 2024 consultation: the HK$10–20 and HK$20–50 bands moved to ticks of 0.01 and 0.02 (cuts of 50% and 60%), and the bands from 0.25 to 10.00 were merged into one with a tick of 0.005 — both phases are already reflected in the Second Schedule to the Rules of the Exchange. A side effect that is barely discussed: the permitted order deviation rule changed at the same time and now reads "24 spreads or 5% of the reference price, whichever is greater". With the tick halved, "24 spreads" physically compressed and the "or 5%" limb started to bind more often.

Short selling. Only securities on the Designated Securities list may be shorted, only on a covered basis (naked shorting is prohibited), and a tick rule applies in every session: no short sale below the reference price in the pre-opening session, below the best ask in the continuous session, or below the reference price in the closing auction. As at 11 September 2026 the list held 1,232 securities, of which 807 were shares and 425 trusts and ETPs; 388 positions (31.5%) are expressly marked as exempt from the tick rule — and those are precisely all the ETPs and trusts. In other words an index fund can be shorted with no tick constraint, while the individual shares inside the same index cannot. On the daily quotations for 3 September 2026 short sales came to HK$42.08 billion, or 21% of total turnover, of which 6 percentage points were ETPs; shorting of securities outside the list was exactly zero, so the prohibition is observed literally (from the designated securities list and HKEX daily quotations).

Settlement. The secondary market cycle is T+2 through HKSCC as central counterparty with continuous net settlement; under Stock Connect securities settle on T and cash on T+1. In April 2026 HKEX published a consultation on moving to T+1; the comment period closed on 18 May 2026, the target launch is the fourth quarter of 2027, and IPOs and Northbound Stock Connect are excluded from the perimeter. The benchmarks the exchange cites: the US moved on 28 May 2024, India completed its transition on 27 January 2023, and the EU, the UK and Switzerland have announced 11 October 2027.

The end of "typhoon holidays". Until 23 September 2024, on a signal No. 8 or above, a black rainstorm warning or a declaration of extreme conditions, the market closed entirely — trading, clearing and settlement. Since that date the Severe Weather Trading regime applies: everything runs normally on any business day. Since 2018 the market had closed for weather 11 times, and in 2023 alone there were four weather events and three full days of suspension. The exchange's argument rested not on lost turnover but on the fact that 41% of 2020 turnover came from international participants, who have other markets open at the time and are left with an exposure they cannot close. Physical infrastructure — bank branches, the depository — still closes.

Indices. The Hang Seng Indexes architecture sets not only the benchmarks but also the gateway into mainland demand.

Data as at 31 July 2026 from the Hang Seng Indexes factsheets. The HSI covers 66.75% of Main Board capitalisation; the top five weights are HSBC 9.20%, Tencent 7.94%, Alibaba-W 7.20%, CCB 5.23% and AIA 4.92%. The HSCI covers about 95% of Main Board capitalisation and splits by size into HSLI (the top 80% of capitalisation), HSMI (the next 15%) and HSSI (the remaining 5%) — and that split is the gateway into Southbound. WVR issuers and secondary listings are admitted to the main indices: Alibaba-W sits in the HSI at a 7.20% weight.

The 8% cap in the Hang Seng Index is a constraint at the rebalancing date, not a permanent limit. In the factsheet as at 31 July 2026 HSBC weighs 9.20% — 120 basis points above the stated ceiling: drift between quarterly reviews is not corrected. For the holder of an HSI ETF this means that actual concentration in a single name regularly exceeds the declared level, and "8%" is a parameter of a procedure rather than a risk limit.

Stock Connect and the A+H wave: the economic case for Hong Kong

Southbound Stock Connect is the channel through which mainland investors buy Hong Kong securities, and it is the main economic argument for listing in Hong Kong rather than Singapore or London.

The eligibility conditions are strict and mechanical. The base rule is inclusion in the Hang Seng Composite indices: LargeCap, MidCap, and SmallCap where market capitalisation is ≥HK$5 billion. For A+H dual-listed companies, the H shares are eligible if the corresponding A share is within the Northbound perimeter. WVR companies and pre-revenue biotech under Chapter 18A do not enter the perimeter automatically: they must satisfy additional criteria set out in the SSE and SZSE rules rather than by the Hong Kong side (HKEX, Stock Connect Information Book for Investors, PDF). Exit works the same way: if average monthly market capitalisation over the 12 months before an index review falls below HK$4 billion, the stock moves to sell-only status. Reviews are tied to the semi-annual HSSI review, so a new IPO does not enter the perimeter immediately — the actual lag runs from a few weeks to six months (HKEX Stock Connect FAQ, version of 6 July 2026, PDF).

Volumes: Southbound ADT in the first half of 2026 was HK$123.1 billion against HK$111.0 billion a year earlier (+11%), Northbound RMB 345.3 billion against RMB 171.3 billion (+102%) (HKEX Interim Results, 19 August 2026, PDF); net Southbound inflows in the first quarter of 2026 exceeded HK$220 billion (HKEX, Q1 2026 Hong Kong Market Update). How the mutual access channels look from the mainland side is described in the market access section of the China material.

The A+H wave is the market's defining story. 2025 saw 19 A+H deals on KPMG's full-year recount, delivering half of all funds raised (HK$136.5 billion); the first half of 2026 alone produced 24 deals — more than the whole of 2025 — and 58% of funds raised, with eight of the ten largest deals of the half-year being A+H. As of June 2026 the pipeline held 116 A+H applications out of 443 filed publicly.

The causes stack up: the CSRC's registration (filing) regime replacing the approval regime from 31 March 2023; the narrowing of the historical H-share discount to A shares through the 2025–2026 rally; mainland champions needing freely convertible capital for overseas capex and M&A; a base commission of 0.9% against 2.2%; the HKEX/SFC accelerated track for A-share issuers with market capitalisation of ≥HK$10 billion, introduced on 18 October 2024; and, finally, the A+H float rule — 10% of the H class or HK$3 billion — which allows a listing with almost no dilution of control. The mainland leg of this route, the SSE and the STAR Market, is covered separately in the material on listing in Shanghai.

The scale of the venue as it stands: Hong Kong finished 2025 first in the world by IPO proceeds for the first time since 2019 — 100–119 listings and HK$272–286 billion depending on the counting methodology; as at the end of July 2026 there were 2,763 listed companies with a market capitalisation of around HK$46.8 trillion, and HK$328.2 billion raised in January–July (+154% year on year) (China Daily HK, 7 August 2026). In the first half of 2026, however, HKEX ranked second globally behind Nasdaq: a single SpaceX IPO of US$85.7 billion (per the Nasdaq newsroom) accounted for 45% of global half-year volume. That is a statistical artefact rather than lost momentum, but anyone deciding on the strength of a "number one in the world" argument needs to understand the difference.

Holder rights: disclosure, privatisation and the absence of class actions

Minority rights in Hong Kong are protected by a strong disclosure regime and a double lock on privatisation, but they lack the principal instrument of Anglo-Saxon markets — the class action.

Disclosure of substantial interests is governed by Part XV of the Securities and Futures Ordinance (Cap. 571). The substantial shareholder threshold is 5% of any class of voting shares. Notification periods: 3 business days for ordinary events and for directors and chief executives, 10 business days for an initial notification. Short positions are disclosed above 1%, but only where a notifiable long position of 5% or more exists at the same time. The duty arises on first reaching 5%, on falling below 5%, on crossing any whole percentage level above 5% (from 6.8% to 7.1%, for instance), on a change in the nature of the interest, on the creation or extinction of a short position above 1%, and on the listing of the corporation's shares (SFC, Part XV SFO). For a founder that means the post-IPO ownership structure becomes publicly trackable to the percentage point.

A mandatory offer arises under Rule 26 of the Takeovers Code on holding 30% or more of the voting rights — a threshold that coincides with the UK's 30% only nominally, because it is applied by a body with no statutory powers whose sanction is exclusion from the market.

Privatisation: the double lock. A scheme of arrangement under Rule 2.10 requires two conditions at once: at least 75% of the votes attaching to disinterested shares in favour and no more than 10% of all disinterested shares against. A delisting by offer under Rule 2.2 runs on the same 75% threshold with the same 10% blocking level, and additionally requires the offeror to exercise compulsory acquisition rights. Rule 2.3 puts all costs on the promoter of a failed scheme where the independent committee did not find it fair and reasonable. There is no headcount test in the text of the rule — the 10% mechanism replaces it. The practical meaning of the construction: a holder of 10.1% of the free float can single-handedly block a buy-out at an unfair price, which makes Hong Kong privatisations materially more expensive for a controlling shareholder than offshore schemes without such a lock.

Voting through a nominee. The registered holder of almost all Hong Kong securities is HKSCC Nominees Limited and the ultimate beneficiary never appears on the issuer's register, so an investor votes not directly but through whichever CCASS participant carries the position on the record date; the same order applies to Southbound investors. That chain is set out at length — from the side of a mainland holder buying A shares through the same infrastructure — in the material on listing in Shanghai.

There is no class action in Hong Kong. The Law Reform Commission recommended introducing a collective redress mechanism on 28 May 2012, starting with consumer disputes — fourteen years later the recommendation is unimplemented. What operates instead is regulatory restitution: in the 2025/26 financial year alone the SFC obtained a HK$595 million compensation order in the Superb Summit case and a HK$1 billion settlement with Evergrande's auditor. In scale that is comparable to class actions, but it is launched at the SFC's discretion under ss. 213–214 SFO. A holder can neither start the process, nor shape what it covers, nor expect redress where the regulator decides not to go to court. When planning a position in Hong Kong paper, litigation cannot be counted as part of the return.

The currency regime: LERS, the band and the price of stability

The Linked Exchange Rate System is a currency board regime in force since 17 October 1983, under which the whole of Hong Kong's monetary base is fully backed by US dollar assets of the Exchange Fund and the rate is held within a band of 7.75–7.85 Hong Kong dollars to the US dollar.

The chronology of the construction: the Exchange Fund Bills programme in March 1990; real-time gross settlement and a proper definition of the Aggregate Balance in December 1996; the introduction of a Convertibility Undertaking on the aggregate balance in September 1998; and the shift of the undertaking rate from 7.7500 to 7.8000 by one pip per calendar day from April 1999. The current symmetric construction was introduced on 18 May 2005: an HKMA undertaking to sell Hong Kong dollars to banks at 7.75 (strong side) and to buy at 7.85 (weak side), with a Convertibility Zone in between (HKMA, milestones of monetary reform).

The adjustment mechanism is automatic: capital inflow presses the strong side, the HKMA sells Hong Kong dollars, the Aggregate Balance rises, local rates fall and the rate moves off the edge. Outflow presses the weak side, the HKMA buys currency, the balance contracts and rates rise. There is no discretionary decision anywhere in that chain — and that is precisely what holders of Hong Kong assets pay for.

The liquidity figures come from HKMA Open API, daily interbank liquidity statistics. The range is tenfold — from HK$44.5 billion in May 2023 to HK$458 billion in November 2020.

2025 is the only year in the regime's recent history in which both sides of the band were triggered within ten weeks. On 7–8 May the HKMA injected +HK$129.4 billion on the strong side (a single day's operation on 7 May of HK$116.6 billion, the largest in the observable series), and between 27 June and 15 August it withdrew −HK$120.0 billion on the weak side. The Aggregate Balance travelled 45 → 176 → 54 billion in four months. Rates responded accordingly: overnight HIBOR was 4.43% in April, 0.01% on 26 May and 3.56% by the end of August; one-month HIBOR ran 3.95% → 0.52% → 3.30% while the base rate stayed at 4.75%. By contrast, in 2021, in 2024 and across the whole of 2026 to 4 September the Convertibility Undertakings were not triggered once.

Currency risk for a dollar-based holder of Hong Kong paper is tightly bounded: a band of 7.75–7.85 allows a maximum of about ±0.64% from the centre, and that is an HKMA undertaking rather than a policy stance. The price of that stability is interest rate risk: local rates are not tied to dollar rates and diverge from them by hundreds of basis points. In May–June 2025 the gap between one-month HIBOR and the base rate exceeded 400 basis points; on 4 September 2026 it was 116 basis points (2.84% against 4.00%). For the equity market the effect is direct: the collapse in HIBOR in the summer of 2025 made margin funding and IPO subscription cheap, and the subsequent contraction of the Aggregate Balance turned rates back up. And a third, less visible layer: the Hong Kong dollar's effective exchange rate index fell from 107.8 to 100.3 over two years — the peg means importing the dollar's dynamics against every other currency.

The investor's side: how to hold Hong Kong paper

A foreign private investor buys Hong Kong shares directly through any international broker with SEHK access, and needs Stock Connect in neither direction to do so; nor is a local Hong Kong bank account required to buy the stock — settlement runs through the broker.

These two channels are constantly conflated. Southbound is the direction in which mainland investors buy Hong Kong securities; Northbound is the reverse, buying mainland A shares through Hong Kong infrastructure. A holder outside the mainland cannot use Southbound and does not need it: it matters as demand for the same stock — a liquidity and valuation factor, not a way to buy. The eligibility criteria for Southbound are set out above.

Custody. Settlement and record-keeping run through CCASS, the depository and clearing system of HKSCC, a subsidiary of HKEX; securities in it are registered to HKSCC Nominees Limited. A holder is recorded either in the account of a broker that is a CCASS participant, as beneficial owner inside an omnibus, or in their own Investor Participant account. The direct account is close to free: opening, maintenance and closing carry no charge, and settlement costs 0.002% of value (minimum HK$2, maximum HK$100) (HKSCC Operational Procedures, Section 22, PDF). The difference is not price but where the risk sits: inside an omnibus a position is reconstructed from the intermediary's records if the broker fails, while an Investor Participant is known to the depository by name, but without margin lending.

Tax for a non-resident holder splits in two.

A Hong Kong share arrives with no tax at source; an H share arrives with Chinese tax already taken (withholding tax).

Professional investor status. Thresholds are set by the Securities and Futures (Professional Investor) Rules: an individual, a portfolio of ≥HK$8 million or equivalent; a trust corporation, assets under trust of ≥HK$40 million; a corporation or partnership, a portfolio of ≥HK$8 million or total assets of ≥HK$40 million (SFC, LegCo Brief, PDF). It opens professional-investor-only paper, private placements without a prospectus and structured products, but does not switch off base protections: since 25 March 2016 an individual PI cannot be deprived of the suitability test, KYC and a written client agreement — only institutional PIs, and corporate PIs on the intermediary's assessment, are exempt. The consequence: dim sum under Chapter 37 carries a minimum denomination of ≥HK$500,000, and at 2 January 2026, 1,302 of the 1,351 bonds listed on HKEX — 96% — were issued on that basis (Hong Kong Government reply to LegCo, 4 February 2026). The retail route into renminbi debt runs through a fund (accredited investor).

Currency. Currency risk for a dollar-based holder is bounded by the width of the 7.75–7.85 band — no more than ~1.3% — and that is an HKMA undertaking rather than a policy stance; from 30 December 2025 to 22 April 2026 the rate held within 7.7818–7.8387 and neither undertaking was triggered (HKMA, Currency Board Operations, 15 June 2026, PDF). The price of that stability is transferred into the interest rate — the mechanics and the 2025 episodes are set out above. CNH is pegged to nothing, so dim sum is both issuer credit risk and an open offshore renminbi position.

What the reforms change for a holder. Since 4 August 2025 a large issuer can list by placing 10% of its capital: less stock in free circulation, a wider spread for the minority holder. Since 1 January 2026 a float breach no longer triggers an automatic trading halt — instead a marker against the ticker and 18 months to cure. Southbound inclusion comes at the next HSSI review, not at listing, so a fresh IPO has no mainland demand for weeks or months. Venue liquidity has grown: headline ADT in the first half of 2026 was HK$283.0 billion against HK$240.2 billion a year earlier, +18% and a record half-year (HKEX Interim Results, 19 August 2026, PDF).

Who Hong Kong suits, and who it does not

Choosing a venue means weighing three things: where the buyer of your stock sits, what entry costs, and which disclosure obligations you are willing to carry for life.

The table sets the HKEX Main Board against the five venues it is most often weighed against: the Nasdaq Global Market, the NYSE, the LSE (equity shares in commercial companies), SGX Mainboard and the SSE STAR Market. The wider grid of thirteen boards — adding GEM, SGX Catalist, ChiNext, the Tokyo Prime and Growth markets, KOSPI, KOSDAQ and Nasdaq Dubai, and reading public float, rule-based lock-up and the gatekeeper filter as separate axes — is in listing venues for Asian issuers.

Six venues on the axes that decide

The entry gate is the column issuers study hardest and the one that decides least. Every venue in the table admits a loss-making company by some route, and HKEX's HK$500 million floor is the lowest quantitative bar of the three large venues. What actually excludes a deal is the cost column read against proceeds: below roughly HK$500 million of proceeds a Hong Kong listing spends a double-digit share of the money raised, and no rule threshold says so. The mainland rows price out at a flat 9–11% regardless of size, because the fee structure there is neither negotiated nor success-linked; the American rows run 5–7% in commission alone, against an average base commission of 1.5% in Hong Kong in 2025 and 0.9% on A-to-H deals. On a billion-dollar deal that difference is worth more than any valuation premium the comparison usually turns on.

The mainland column is the one that cannot be bought later. HKEX is the only venue in the table that combines a foreign-issuer-friendly wrapper with a channel into mainland savings, and even there the channel opens only at the next index review rather than on the listing day. The STAR Market has the capital and not the wrapper: it takes no foreign issuers at all, and its proceeds are renminbi with constrained repatriation. Nasdaq, the NYSE, the LSE and SGX have the wrapper and no channel. For an issuer whose profit centre sits outside the PRC the currency question decides the row before the valuation question is reached — the same order of questions the Shanghai venues impose from the other side.

Hong Kong beats Nasdaq where the business, its revenue and its counterparties sit in Greater China and Asia-Pacific; where an A-share listing exists or is planned (in which case A+H is practically the only option); where the company qualifies under Chapter 18A or 18C and values the TECH channel; where Southbound access is critical; where there is sensitivity to US disclosure, PCAOB inspections and HFCAA risk; and where the deal exceeds HK$3 billion, since commissions are a multiple below the American 5–7%.

Nasdaq or NYSE win where you need depth of long-term capital for a loss-making technology story with no China angle, high secondary market liquidity, and the ability to pay for US M&A in your own stock. The LSE has been effectively out of contention for an Asian issuer since 2023–2025 on liquidity and valuation — the Shein case is instructive, having passed over New York and London to list in Hong Kong. SGX has lower entry thresholds and suits REIT and business trust structures and family offices better, but it is radically weaker on liquidity and offers no channel into mainland capital; the corporate and tax comparison of the two jurisdictions sits in Hong Kong versus Singapore.

Hong Kong is a poor fit for deals below HK$500 million, where costs consume the proceeds; for companies with no Asian history and no coherent China narrative, which risk becoming illiquid orphans in the order book; and for anyone who needs immediate Southbound inclusion, since that arrives no earlier than the next index review.

Issuer profile and venue

The Russian angle: the route is closed by compliance, not by rules

The constraint on companies with a Russian connection is not regulatory but a compliance matter: HKEX does not formally prohibit such listings, but no private participant in the chain will accept one.

Formally, HKEX accepted Russia as a jurisdiction of incorporation in January 2016 and published a Country Guide under which a Russian-incorporated company could list only depositary receipts, and only on the Main Board, because shares of a Russian public joint-stock company exist only in uncertificated form (HKEX, Country Guide – Russia (PDF)). A Hong Kong, Bermuda or Cayman holding company with Russian subsidiaries lists shares directly. Since 1 January 2022 HKEX has kept no list of acceptable jurisdictions, and the Russian guide, like every country guide, has been archived without further updates (HKEX, archived country guides).

In practice the route has been closed at gatekeeper level since 2022. A sponsor holding an SFC Type 6 licence is always an arm of a global or major Chinese bank with dollar clearing, and it will not sign off on such a deal; without a sponsor an application is impossible in principle. Big Four auditors will not issue the accountants' report. Receiving bank, share registrar and settlement infrastructure all run into the OFAC, EU and UK perimeters. In April 2026 the EU sanctioned 60 third-country entities, Hong Kong companies among them, for facilitating Russian access to technology, which sharpened local providers' caution even about indirect links. Market precedent: Rusal (ticker 486) remains listed, but it listed back in 2010 as a Jersey company and redomiciled to Russia only on 25 September 2020, and in 2018 it lost roughly 40% of its market capitalisation in a day on OFAC sanctions and was dropped from the indices.

Tax for the founder

The tax side of a Hong Kong listing is defined by the territorial basis of profits tax, the absence of capital gains tax and a low stamp duty on share transfers.

The rates follow PwC, Hong Kong Tax Facts and Figures 2026/27 (PDF).

The issue of new shares in an IPO carries no stamp duty — the charge arises on transfers of existing securities. Watch the definition of Hong Kong stock: it turns on whether the transfer must be registered in Hong Kong, so a Cayman holding company with a Hong Kong register falls within the charge.

The main trap is the FSIE (Foreign-Sourced Income Exemption) regime, in force since 1 January 2023 and extended to disposal gains from 1 January 2024. It deems certain foreign income, including gains on the disposal of assets, to be Hong Kong sourced and chargeable to profits tax where the recipient is part of a multinational group and fails the economic substance, nexus or participation exemption tests. In other words, the proposition that "Hong Kong has no capital gains tax" holds for a resident individual selling shares but is not automatically true for a holding company inside a group. The exit structure has to be designed around FSIE before the transaction, not after, starting with the question of the holding company's tax residence.

Dim sum: the origin of offshore renminbi and the phases of the market

The offshore renminbi did not emerge as a market phenomenon but as a sequence of administrative decisions: a clearing bank in 2003, the cross-border settlement pilot of 2009, and the revised settlement agreement of 19 July 2010, after which CNH began to circulate freely in Hong Kong.

Infrastructure. On 24 December 2003 the PBOC appointed Bank of China (Hong Kong) as clearing bank for renminbi business; its settlement account at the PBOC's Shenzhen branch is the single pipe connecting the offshore pool to onshore. The first deposits appear in HKMA statistics from February 2004 — RMB 12.1 billion across 38 banks at year end. On 29 June 2009 a memorandum was signed preparing the pilot for renminbi settlement of cross-border trade; on 22 June 2010 the pilot was extended to 20 mainland provinces and municipalities and to trade with any part of the world. The key date is 19 July 2010: the PBOC and BOCHK signed a revised settlement agreement removing restrictions on opening renminbi accounts for financial institutions and on transfers between account holders. From that moment there exists an asset nominally identical to CNY but not fully arbitrageable against it — hence two exchange rates.

The account follows HKMA press release, 19 October 2010; HKMA Quarterly Bulletin, March 2011 (PDF); HKMA Quarterly Bulletin 01/2026, "The Hong Kong Bond Market in 2025" (PDF); HKMA Open API, renminbi deposits.

Two caveats for reading those series. First, the HKMA publishes two incompatible series — "bonds" (excluding certificates of deposit, up to and including 2022) and "CNH debt securities" (including CDs, commercial paper and ABS, from 2023); comparing years directly across the 2022–2023 boundary produces a false jump. Second, the common claim that McDonald's was the first offshore renminbi corporate issuer is wrong — on the HKMA's own wording the first was Hopewell Highway Infrastructure in July 2010, and the significance of McDonald's lies elsewhere: it was the first issuer with no China connection at all, proving that the pool of borrowers was bounded by economics rather than by regulation.

The deposit base on which the whole market rests: RMB 314.9 billion at the end of 2010 (a fivefold jump in a year, with the number of banks rising from 60 to 111 — a direct consequence of the 19 July 2010 agreement), RMB 1,003.6 billion at the 2014 peak, RMB 507.3 billion at the March 2017 trough, RMB 960.1 billion at the end of 2025, and RMB 1,134.7 billion in May 2026 — the all-time high of the series. Historical offshore liquidity squeezes show what this market risks: overnight CNH HIBOR fixed at 66.8% in mid-January 2016 and at 61.3% on 6 January 2017, after which the three-month rate held around 10% and 4.6% respectively. There have been no squeezes in 2025–2026: three-month CNH HIBOR has stayed below 2% since April 2025.

Dim sum: the mechanics of an issue

A dim sum bond is a bond denominated in offshore renminbi (CNH), issued and settled outside mainland China and predominantly in Hong Kong; legally it is an ordinary eurobond, just in a different currency.

The governing law is usually English or New York, the documentation follows ICMA standards, settlement runs through the CMU or through Euroclear and Clearstream, and no filing with any Chinese authority is required. The issue itself is unregulated — the market is offshore, and regulation enters at exactly two points: listing and settlement.

There is no restriction on the issuer's nationality. The actual roster in 2025–2026: Chinese technology corporates (the main driver), Chinese state banks and their overseas branches (mostly certificates of deposit), provincial and municipal people's governments (Shenzhen, Hainan, Guangdong), China's Ministry of Finance with benchmark CNH CGB issues that build the curve, the PBOC with bills as an offshore liquidity management tool, the multilateral development banks AIIB and ADB, sovereigns and quasi-sovereigns (Indonesia with a 2025 debut, the Development Bank of Kazakhstan, KazMunayGas) and international corporates — Nestlé, Chubb, Temasek.

Listing is formally optional, but it is needed for tax purposes and for the mandate restrictions many institutional investors operate under. The route is Chapter 37 of the Main Board Rules, the professional-investors-only regime.

The listing mechanics follow HKEX, Summary of Chapter 37 Listing Requirements (PDF); HKEX Main Board Fees Rules (PDF). Post-listing obligations are minimal: respond to exchange enquiries, publish material announcements, and file annual and interim accounts.

The economics of an issue. Exchange fees are negligible; the real costs are underwriting and management fees of 15–35 basis points of size for investment grade, issuer's and dealers' counsel at US$150,000–400,000 on a standalone issue, ratings from S&P, Moody's or Fitch, and trustee, fiscal agent and listing agent fees. Realistically: a standalone issue takes three to six weeks from mandate to settlement at an all-in cost of 25–50 basis points; a drawdown under an existing MTN programme takes three to seven business days at 10–20 basis points (market estimate based on observed transactions). That is an order of magnitude faster and cheaper than an IPO, and faster than a panda bond. The HKMA also subsidises part of the cost of issuing: the Digital Bond Grant Scheme for qualifying tokenised issues and the Green and Sustainable Finance Grant Scheme for green and transition paper, with the grant size set by the schemes' current terms (Hong Kong Budget 2026–27, February 2026, PDF).

Settlement runs through the CMU. The Central Moneymarkets Unit has been operated since early 2025 by CMU OmniClear Limited, an HKMA subsidiary. At the end of 2025 assets under custody stood at HK$5.2 trillion (a record, +9%), of which debt securities were HK$4.1 trillion (+19%); new issuance for the year was HK$1.7 trillion (+10%, an all-time high); and the CMU's share of global new dim sum issuance is 95% (HKMA Quarterly Bulletin 01/2026, PDF). In December 2025 HKEX became a strategic shareholder in CMU OmniClear Holdings, aiming at unified post-trade infrastructure across equities and debt; membership has been widened to foreign regulated institutions, sovereigns and supranationals, and in February 2026 the Central Bank of the UAE joined the CMU. Holding and recording securities on the investor side is covered in the material on securities custody.

The investor base: Hong Kong and Asian banks with CNH treasury books, asset managers with CNH mandates, Asian insurers, private banking and family offices in Hong Kong and Singapore (a visible segment for three to five-year paper from known names), mainland institutions via Southbound Bond Connect, and central banks in Ministry of Finance and MDB paper.

A private holder enters that base only through a threshold. The minimum denomination under Chapter 37 is HK$500,000 and the regime is professional-investors-only, so a direct purchase needs a portfolio from HK$8 million. Secondary liquidity is off-exchange to match: paper listed under Chapter 37 trades mostly OTC rather than on the HKEX order book (Hong Kong Government reply to LegCo, 4 February 2026). The retail alternative to the same exposure is a fund or an ETF in offshore renminbi.

The dim sum market in 2025–⁠2026: volumes, rates, liquidity

The capacity of the dim sum market is bounded by the offshore renminbi pool — the mass of CNH sitting outside China's capital controls — which is why pricing is built off CNH HIBOR rather than onshore rates.

The numbers demand care, because headline statistics mix three different perimeters. The first is the HKMA perimeter: new issuance of renminbi debt securities in Hong Kong, meaning bonds together with certificates of deposit, commercial paper and ABS; in 2025 that was RMB 1,100.9 billion (US$157.2 billion), a rise of only 2.7% year on year. The same series excluding certificates of deposit was US$112.4 billion, the corporate segment (that is, excluding sovereign and sub-sovereign issuers) was US$90.5 billion, and the corporate segment excluding CDs was US$45.6 billion. Meanwhile the amount outstanding at the end of 2025 rose 27.6% to RMB 1,607.3 billion (US$229.6 billion) (HKMA Quarterly Bulletin 01/2026, "The Hong Kong Bond Market in 2025", PDF). Those are two different stories: the stock is growing on longer tenors, not on annual flow.

The second is the bond segment excluding certificates of deposit, the basis market analysts use: RMB 358 billion in the first half of 2026 (Goldman Sachs via SCMP, 10 August 2026) and RMB 683.04 billion by 14 August 2026 (SCMP, 24 August 2026).

The third is total issuance for a period as reported in the business press: the widely quoted "+180% year on year in March 2026" and "around RMB 400 billion in the first quarter of 2026, +14%" both include a single PBOC transaction of RMB 60 billion — strip it out and March growth is +72% — while the perimeter itself, whether certificates of deposit are counted, is not disclosed by the source (Caixin, 2 April 2026). The three series cannot be compared with each other; an issuer sizing capacity for its own deal should look at the corporate segment excluding CDs.

The rate detail. TMT issuance rose 82% in 2025 to RMB 31 billion: Alibaba RMB 17 billion (November 2024), Baidu RMB 14.4 billion in two tranches (2025), Tencent RMB 9 billion (September 2025) including RMB 1 billion at 30 years subscribed 8.6x, Meituan RMB 7.1 billion (November 2025), Kuaishou RMB 3.5 billion (January 2026). The pricing benchmark to anchor on: JD.com placed RMB 10 billion in April 2026 — RMB 7.5 billion at five years with a 2.05% coupon and RMB 2.5 billion at ten years at 2.75%, rated A− by S&P (Caixin, 21 April 2026). International issuers grew 28.5% in 2025: Nestlé RMB 2 billion (May 2025), Temasek RMB 5.5 billion (July 2025), Chubb RMB 4.5 billion (August 2025), the Development Bank of Kazakhstan RMB 2 billion (September 2025), KazMunayGas RMB 1.25 billion (October 2025).

Pricing: the base is CNH HIBOR (the TMA fixing in Hong Kong), not onshore SHIBOR. Average dim sum yields in May 2025 were 2.29% against 1.64% onshore at an average duration of 3.6 years against 5 years — meaning offshore pays a premium of around 65 basis points for lower liquidity and shorter tenor. Primary market spreads have compressed to 10–20 basis points, a sign of excess demand.

The frequently quoted "average renminbi funding cost of around 0.7%" describes the short, high-grade end — the level of CNH HIBOR and certificates of deposit — rather than the whole curve: yields on outstanding dim sum paper run roughly three times higher. The comparison to draw is with dollar funding of comparable quality — SOFR plus 50–90 basis points, or 4.15–4.45% (The Paper, 6 April 2026), consistent with the HKMA base rate of 4.00% on 4 September 2026: the gross gap to the 2.29% average dim sum yield is roughly 190–215 basis points. That is the gap before hedging, though; issuers raising CNH and swapping the proceeds into dollars kept up to 40 basis points of it against issuing in dollars directly.

There is a structural refinancing driver behind the demand: a third of Chinese corporates' dollar bonds, out of some US$750 billion outstanding, matures within the next two years.

The principal technical risk in dim sum is liquidity, not credit. Overnight CNH HIBOR is prone to sharp spikes: when offshore liquidity tightens, traditionally against the backdrop of a currency defence, the fixing reached 66.8% in mid-January 2016 and 61.3% on 6 January 2017, with the three-month rate rising to around 10% and 4.6% in those episodes, and the primary market becomes temporarily unusable in such windows. The present regime is the opposite: there were no squeezes in 2025–2026, the three-month rate has stayed below 2% since April 2025, and the offshore cost of renminbi is in effect held down by the onshore benchmark through the HKMA facility, which lends renminbi at SHIBOR. The risk has not disappeared — it has moved from the market to the regulator's policy. The second constraint, named by participants themselves, is insufficient capacity for very large and very long deals and the absence of hedging instruments at the long end. Tencent's RMB 1 billion thirty-year tranche was an event for precisely that reason.

The regulator's tool for managing that risk is the HKMA's renminbi facilities, and here almost all available commentary is out of date. The chronology: February 2025, the RMB Trade Financing Liquidity Facility launched; October 2025, it is replaced and widened into the RMB Business Facility (RBF) at RMB 100 billion, with eligible uses extended from trade finance to capex and term working capital loans; 26 January 2026, a doubling to RMB 200 billion from 2 February 2026 is announced after the previous quota was fully allocated across 40 participating banks; announced on 7 July 2026 and effective 10 July 2026, the size is raised to RMB 500 billion, tenors extended to 9 months, 2 years and 3 years, and by July more than 90% of the quota had been allocated (HKMA, 7 July 2026, PDF; Government Information Services, 26 January 2026).

The model is hub-and-spoke with Hong Kong as the hub, funded off the swap line with the PBOC. Also under study: a tender mechanism for seven-day offshore renminbi liquidity in repo form, and HKMA issuance of its own short-dated offshore renminbi instruments to build out the curve. How this liquidity translates into the price of credit for a borrower is covered in the material on the cost of money in China.

Southbound Bond Connect turns dim sum from a purely offshore instrument into a channel to mainland liquidity. It launched in 2021; in July 2025 the eligible investor base was widened from banks to brokers, fund managers, insurers and wealth management companies outside the QDII quotas, after which issuance roughly doubled to around RMB 102 billion over August–September 2025; in June 2026 the largest Chinese insurers began buying dim sum through the widened channel; and on 7 July 2026 the annual quota was raised from RMB 500 billion to RMB 800 billion, the perimeter extended to Hong Kong dollar bonds and derivatives of renminbi paper as well as to the Macau market, with repo against Southbound holdings introduced (The Standard, 7 July 2026). The widening of the investor base in 2025 and of the quota in 2026 is precisely why spreads compressed to 10–20 basis points.

Dim sum versus panda bonds

Dim sum and panda are two ways of borrowing in renminbi: the first offshore in CNH with no Chinese regulation, the second onshore in CNY with mandatory registration and capital controls.

• Speed. Dim sum by a wide margin: three to six weeks for a standalone issue and three to seven business days for a drawdown, against months of onshore registration procedures.
• Use of proceeds. Dim sum gives full freedom, like any eurobond; panda proceeds may be moved out of the PRC (permitted since 1 January 2023, but through a dedicated account and within the use of proceeds stated in the prospectus), and the mechanics of those constraints are set out in the material on panda bonds.
• Headline rate. Panda is cheaper, but the benchmark has to be the right one: an onshore issue prices at a spread to the policy bank curve, principally China Development Bank, rather than to the CGB government curve — the gap between the two curves reflects a tax wedge, not credit risk. The actual level in the first half of 2026 was a weighted average of 1.85% across all panda issues and 1.94% on three-year AAA paper (Far East Credit 远东资信, 7 August 2026). Dim sum pays a premium of roughly 65 basis points on average yield. The frequently quoted "around 100 basis points" attached to panda issues is not a spread to any curve but FDL's estimate of the post-swap currency effect: for an emerging-market sovereign, hedged renminbi comes out roughly 100 basis points dearer than dollars.
• All-in cost. Dim sum is generally cheaper: on the panda route an issuer in practice often needs a local rating and a guarantee wrapper, although formally neither is required — 70 of 114 tranches were placed unrated in 2025 — and legal costs are higher, while dim sum lets an MTN programme be reused.
• Depth of demand. For short, high-quality paper of a few billion renminbi the two are comparable. For long tenors, sub-investment grade, and any issuer that needs the money outside the PRC, dim sum has no competition, and the gap widens as Southbound expands.
• When panda makes sense. When the money is genuinely needed inside the PRC — capex for a Chinese subsidiary, local refinancing — or when the political and reputational effect of entering the onshore market is itself the objective.

Here panda is treated only as an alternative to dim sum for the same issuer: the onshore route in full — registration, reporting, repatriation and capital controls — is the subject of a separate material.

Equity or debt: the fork by funding purpose

The choice between an IPO and a bond is decided not by the cost of capital but by what you are buying with the money: permanent capital and public status, or term money with no dilution.

The practical sequence most Asian issuers follow is the reverse of the familiar one: dim sum first, as a way to build a credit history, public reporting and a rating, and only then an IPO — so that by the time the A1 is filed the company already has tested accounts, a working IR function and an external rating, which is a meaningful share of the preparation budget.
