Concept
In insurance, you can issue policies under someone else's license. An MGA (managing general agent), also known as a coverholder, receives delegated underwriting authority—the right to underwrite and issue policies on the "paper" of a licensed insurer under binding authority. In the Lloyd's market, this is a coverholder working with a managing agent. This is the insurance vertical of the same license-rental pattern as BaaS in banking, agents in payments, and host AIFM in funds—general overview in embedded finance.
Fronting is when a licensed fronting carrier provides the "paper" (a policy under its license and rating), while the insurance risk is transferred through reinsurance to a reinsurer or to a proprietary captive. The MGA brings in and services the business; the carrier provides the license and rating; the risk is held by whoever reinsured it.
Where it comes from: the model grew up with program business and the excess-and-surplus (E&S) market. As specialist MGAs multiplied, they needed licensed paper and a rated balance sheet without becoming insurers themselves, and a class of fronting carriers formed to supply exactly that. The scale follows the E&S boom — US MGA premium roughly doubled from about $51 billion in 2020 to around $90 billion in 2024.
🍓 The licensed carrier, whose paper the policies are written on, answers to the regulator for the whole program, while the MGA handles distribution and claims. The Vesttoo collapse (2023, roughly $4 billion in forged letters of credit backing reinsurance) made that responsibility concrete: through 2024–2025 state regulators and carriers tightened collateral verification and required fronting carriers to keep genuine operational control over the programs they front.
How It Works
Three roles. The MGA sells, underwrites within the mandate, and services policies and claims. The fronting carrier issues the policy under its license and A-rating, so the policy is accepted by clients and counterparties. The reinsurer or captive assumes the economic risk. Everything is tied together by binding authority (binder)—an agreement that describes exactly what the MGA is authorized to sign on behalf of the carrier.
What You Need to Launch
The MGA must be a licensed producer and hold a separate MGA license (by state). You cannot conduct business without written contracts with all parties. You also need a fronting carrier and binder, errors and omissions insurance (E&O), and a surety bond.
| Element | Requirement |
|---|---|
| Licenses | producer + separate MGA license (by state) |
| E&O (errors & omissions insurance) | $250K or 25% of direct written premium from the previous year—whichever is greater |
| Surety bond | per NAIC Model Act; around $50K or 10% of premiums handled (depends on state) |
| Contracts | written agreement with all parties—business cannot be conducted without it |
| Infrastructure | fronting carrier + binding authority (binder) |
Compliance
Obligations are defined by the binder: permitted lines, territory, limits, commission rates, bordereaux reporting (regular registers of issued policies and claims), carrier audit rights, and termination conditions. The carrier is obligated to substantively control the program: verify underwriting, reporting, and claims settlement, as well as collateral for retained risk. After Vesttoo, collateral verification and operational oversight have been tightened.
How It's Done in the Market
Fronting carriers commonly used to open programs include Clear Blue, Trisura, Accredited, State National (Markel), MS Transverse (MS&AD), Knight and Sutton National. Ownership moves fast: Accredited became independent under Onex in 2024 after parent R&Q went into liquidation, and Transverse now sits inside MS&AD as MS Transverse. The field is mapped in the carrier catalog below. The economics are commission-led — commissions are around 60–80% of MGA revenue, retail commission runs 10–15% of premium plus an override, and the carrier charges a fronting fee and holds collateral against any retained risk.
What to look for when choosing a fronting carrier: rating and admitted/non-admitted status (determines where you can sell), collateral requirements, depth of operational control (higher after Vesttoo), binder terms—audit and termination, willingness to work with your lines and volumes. Delegated authorities at Lloyd's and fronting practice provide guidance on deal structure.
Fronting Carriers: Who's Who
The carriers themselves deserve a closer look. Classic fronting today is almost always hybrid: the carrier retains 10–30% of the risk to keep interests aligned, while the rest is ceded to reinsurers or the program's captive against collateral — letters of credit, trust accounts or funds withheld. If the reinsurer fails to pay, the obligation to the policyholder stays with the carrier, which is why the quality and verifiability of collateral matter as much as the fronting fee itself.
The Carrier Catalog
- State National (Markel) — the largest fronting carrier, over US$3.64B DPW in 2024; acquired by Markel in 2017 for $919M.
- MS Transverse — the largest hybrid fronting insurer in the US by GWP in 2024; MS&AD closed the acquisition of Transverse in January 2023 (~US$400M plus earnout), and AM Best upgraded the rating to A+ in 2025.
- Clear Blue — about US$1.67B DPW; fronted several Vesttoo deals, rating restored to A- in November 2023 after a US$25M recapitalization; separately litigating against China Construction Bank over forged letters of credit.
- Trisura — US$1.40B DPW; Canadian group with US fronting operations.
- Accredited (ex-R&Q) — sold to Onex for US$465M (closed June 2024, amid the liquidation of parent R&Q); A- by AM Best, operates in Europe, UK and US, over US$2.1B in premium and 70+ programs.
- Sutton National, Knight — Sutton wrote over US$1B in 2024 premium and is itself an M&A focus; Knight and others are growing niche players.
The Market in Numbers
Fronting is no longer a niche. Per Conning's estimate, about US$18B of premium flowed through fronting carriers in 2024 — up 26% year on year — while the US MGA market topped US$114B (+16%). Four carriers — Accelerant, Sutton, MS Transverse and State National — each wrote over US$1B and together hold roughly 43% of the fronting market; the rest is split among some two dozen players, and the entry bar for new programs keeps rising.
Vesttoo in precise numbers: roughly US$3.36B of forged standby letters of credit, at least US$2.81B of them tied to China Construction Bank; about 20% of all LoC collateral held by US fronting carriers turned out to be Vesttoo-linked, and Aon reserved US$197M for related settlements. Hence the "penny tests" — drawing a nominal amount to confirm the bank even knows the letter of credit exists.
The Fintech Analogy
The fronting carrier has a direct structural analogue — the sponsor bank in BaaS: a neobank without its own licence issues cards and accounts on a sponsor bank's paper and BIN, exactly as an MGA issues policies on a carrier's paper. In both cases the licensed entity answers to the regulator and the client, charges a fee and must genuinely supervise its partner — the same logic that underpins embedded finance.
Applicable Regulation
In the US the foundation is the NAIC MGA Model Act (Model #225) — producer plus MGA licence, E&O cover, a surety bond and a mandatory written contract — on top of each state's insurance code. In London the parallel is the delegated authority regime at Lloyd's, where a coverholder binds business under a managing agent's licence. The Vesttoo lesson is now written into supervision: through 2024–2025 state departments ran targeted exams of fronting carriers focused on underwriting oversight and collateral, and the NAIC revisited reinsurance-collateral guidance. Where the perimeter is heading overall sits in regulatory perimeter trends.
| Pros | Cons |
|---|---|
| Issue policies without your own insurance license and capital for risk | The carrier is responsible for the program before the regulator; it controls tightly |
| Access to the fronting carrier's license and rating | Fronting fee and collateral requirements reduce economics |
| High share of commission in MGA revenue (60–80%) | Dependence on carrier and reinsurer; binder can be terminated |
| Flexibility on lines and territories through binder | After Vesttoo—higher collateral and operational oversight requirements |
Why It Matters for a Family Office
For a family office the appeal is access without a balance sheet. A captive or a program built on fronted paper lets the family underwrite its own exposures — property, marine, specialty liability, even parts of life cover — and reach the reinsurance market directly, where the price is actually set. It pairs with insurance-based wrappers such as PPLI and with life insurance as a succession tool, so cover sits inside the holding and succession plan rather than alongside it.
The EU and UK Picture
Outside the US the same pattern runs through different plumbing. At Lloyd's the MGA is a coverholder: a managing agent delegates binding authority, the binder fixes classes, territory, line size and capacity, and the coverholder is listed on Lloyd's register and audited against it. In the UK an MGA is either directly FCA-authorised or an appointed representative of a principal, answering to both the FCA as a distributor and Lloyd's as a delegate. In the EU delegated underwriting runs under the Insurance Distribution Directive, with intermediaries passporting across the bloc and the risk carried by an EU-licensed insurer that reinsures or fronts behind the scenes.
Q/A
Do you need your own insurance license to open an MGA
A full insurer license—no. You need a producer license and a separate MGA license by state, and policies are issued on the "paper" of a fronting carrier under binding authority. A written contract with all parties is mandatory.
Who bears the insurance risk in fronting
Not the fronting carrier economically, but the reinsurer or proprietary captive to whom the risk is transferred. The carrier provides the license and rating and is responsible before the regulator, so it requires collateral for retained risk.
What did the market learn from the Vesttoo case
In 2023, fake letters of credit totaling approximately $4 billion, issued as collateral for reinsurance, were uncovered. After this, regulators and carriers tightened collateral verification and require operational control over programs, not just providing "paper."
Why is a fronting carrier needed if the reinsurer holds the risk
The reinsurer or captive often lacks an admitted license and rating in the required states. The carrier provides the paper, rating, and regulatory access, retaining a portion of the risk and a fronting fee.
Who is liable if the reinsurer fails to pay
The fronting carrier is liable to the policyholder — which is why it requires collateral and holds retention: that is its skin in the game.

FAQ
How long does it take, and what does it cost, to launch a fronted program?
Plan in months. The time goes into the MGA and producer licences, the binder negotiation with the fronting carrier, and the reinsurance or captive that actually holds the risk. Recurring costs are the fronting fee, collateral for retained risk, E&O and the surety bond, plus the carrier's audit and oversight, which have grown heavier since Vesttoo. It is far lighter on capital than owning an insurer, though the licences, fees and collateral are real.
