Personal accounts abroad: banks, neobanks, and source of funds

Partner, Corporate & Commercial

Concept

A personal account is a bank account held by an individual, not a company, in a jurisdiction other than the person's own, used for everyday payments, savings, investments or wealth management. Because the contracting party is the individual, the bank underwrites that person's tax residence, source of wealth and risk profile rather than a corporate balance sheet. Three kinds of institution serve three needs: a retail bank for daily transactions, a private bank for the wealth tier (relationships typically run from USD 1 to 2 million, though entry tiers start lower), and a neobank for fast multi-currency operations.

Three companion notes map the institutions in detail: banks by jurisdiction, neobanks for day-to-day operations, and private banking as a discipline of its own.

Typical tiers of personal banking

Transactional tier

A basic retail bank in the country of residence for everyday payments: mortgage, utility bills, salary, debit/credit cards. Typically a local bank under local deposit protection.

Examples: CaixaBank in Spain, Erste Bank in Austria, DBS in Singapore, HSBC HK for Hong Kong residents.

Wealth management tier

A private banking relationship for investments, custody, and advisory. Typically a Swiss, Singaporean, Hong Kong, or British private bank with AuM from $500k–1M.

Examples: Julius Baer, Pictet, Lombard Odier, DBS Private Bank, HSBC Private Wealth, UBS.

Diversification tier

Additional banking relationships in other jurisdictions for diversification, hedging against single-jurisdiction risk, and access to local investment opportunities.

Examples: CIM Banque (Switzerland multi-currency), Bank Frick (Liechtenstein crypto-friendly), Erste for EU exposure.

Regulatory Map by Jurisdiction

Transparency: from bank secrecy to automatic exchange

For decades the selling point of a foreign personal account was confidentiality. That era has closed. Switzerland gave up automatic banking secrecy when it joined the Common Reporting Standard, exchanging account data from 2017 and 2018 onward, and today more than 100 jurisdictions report balances, interest, dividends and sale proceeds to each holder's country of tax residence. Holding the account is legal; failing to declare it at home is what creates exposure.

US persons sit under a parallel regime. FATCA requires foreign banks to identify American clients wherever they live and report them to the IRS, while the client files an FBAR and Form 8938 at home. A US passport visibly shortens the list of banks willing to onboard, and many private banks decline US clients outright to avoid the compliance burden.

The next extension reaches crypto. Under the OECD's Crypto-Asset Reporting Framework (CARF), exchanges and custodians start collecting client data in 2026 for first automatic exchange in 2027, and the CRS itself is being widened to capture e-money and central-bank digital currencies. The direction is settled: information that once stopped at the border now follows the client home.

Transparency has a side effect at the counter. Compliance costs banks real money, so many have de-risked, closing or refusing accounts for non-residents, certain nationalities, or anyone whose source of wealth is awkward to document. Opening a personal account abroad now turns on clearing due diligence cleanly, which is exactly what banks ask for below.

What banks require from non-resident clients

Swiss banks

• passport and proof of residence in current country of residency;
• source of wealth documents (sale of business, inheritance, profession);
• source of funds documents (specific funds being deposited into the account);
• tax residency certificate;
• for UHNW – detailed wealth narrative with supporting documentation;
• meeting in person (often required for non-EU residents);
• CRS reporting compliance.

Singapore banks

• passport + visa/residence status;
• source of wealth and source of funds;
• proof of address;
• meeting in person for UHNW relationship;
• CRS + FATCA for US-connected persons.

Hong Kong banks

• passport + HK ID (for residents) or non-resident application;
• source of wealth and source of funds;
• proof of address;
• meeting in person at HK branch;
• AMLO compliance documents.

Account opening: general sequence

1. Selecting a jurisdiction aligned with the objective (transactional / wealth / diversification);
2. Choosing a bank in that jurisdiction with regard to minimum balance and required services;
3. Pre-screening—typically through a relationship manager or sales contact at the bank;
4. Submitting documents—KYC pack, source of wealth, source of funds;
5. Compliance review—may take 2–4 weeks for retail tier, 1–3 months for UHNW;
6. Signing the contract and making the initial deposit;
7. Account activation and online banking setup.

For UHNW relationships, a face-to-face meeting in person at the branch is usually required.

When a personal account abroad is appropriate

• residence in one country, business or assets in others—diversification through accounts in applicable jurisdictions;
• multi-currency exposure—USD/EUR/CHF/GBP/SGD for UHNW portfolios;
• wealth management through Swiss or Singapore private banks for a specific capital pool;
• planning cross-border movements (residency change, asset transfer).

Where not suitable

• small capital (< $50k) without residence in applicable jurisdiction — most banks will not accept;
• crypto-only clients — traditional banks limit crypto-related deposits;
• clients with high-risk UBO without strong mitigation;
• attempt to hold operating cash flow through personal account instead of corporate (compliance issue).
