Switzerland is still the world's largest centre for cross-border private wealth. Swiss banks manage around CHF 2.4 trillion of privately held assets booked from abroad, more than 20% of the global total. Opening an account is open to foreigners, but the entry ticket depends on the type of bank, your residence and, above all, how well you can document the origin of your wealth.
This guide covers who can open a Swiss account, realistic minimum deposits, the KYC file banks expect, the main institutions, and how the regulatory framework (FINMA, the Banking Act and the automatic exchange of information) works in 2026.
Can Foreigners Open a Bank Account in Switzerland?
Yes. There is no legal requirement to live in Switzerland to open an account, and nearly half of Swiss banking clients are based abroad. What changes is which banks will take you and on what terms.
Swiss residents (B, C, L or G permit holders) can access retail, cantonal and digital banks, often with no minimum balance. Non-residents are mostly served by private banks and the wealth management arms of universal banks, where the relationship is sized in hundreds of thousands or millions of francs. Several retail banks restrict or refuse clients domiciled abroad, so for most international clients the realistic route is a private bank.
Minimum Deposit Requirements
There is no legal minimum in Switzerland. Each bank sets its own threshold, rarely publishes it, and adjusts it to your country of residence and risk profile. The figures below reflect current market practice for 2026.
For Swiss Residents
- Retail, cantonal and digital banks: usually no minimum for a current account
- Private banking coverage at universal banks: typically from CHF 250K to CHF 1M
- Pure private banks: typically from CHF 1M
For Non-Residents
- Large private banks (Pictet, Lombard Odier, Julius Baer): typically from CHF 3M to CHF 5M
- Mid-sized private banks (UBP, EFG, Vontobel, Edmond de Rothschild): typically from CHF 1M to CHF 3M
- Universal bank wealth divisions (UBS): typically from CHF 1M to CHF 2M or more
Clients from EU and EEA countries generally access lower tiers than clients from higher-risk jurisdictions, who should expect higher minimums and longer reviews. In practice, the larger and better documented the relationship, the more room there is to negotiate fees and services.
Documents Required to Open a Bank Account
Swiss banks apply the Anti-Money Laundering Act, FINMA's Anti-Money Laundering Ordinance and the Swiss Bankers Association's due diligence code (CDB 20), which governs how banks verify the contracting partner and establish the beneficial owner. In practice, the file looks like this.
Basic Requirements
- Valid passport (national ID cards are accepted for some EU nationals)
- Proof of residential address issued within the last three months
- Tax identification number and a self-certification of tax residence (CRS form)
- FATCA status declaration (Form W-9 for US persons, W-8BEN for others)
- Description of professional activity and expected account use
Source of Wealth and Source of Funds
- Evidence of how the wealth was built: sale of a company, inheritance, employment, investments
- Supporting documents: sale and purchase agreements, probate papers, payslips, dividend statements
- Recent tax returns (commonly the last two or three years) showing the assets are declared
- Statements from the bank sending the initial deposit
- Traceability of the wealth: a documented trail linking its origin to the funds being transferred
- Bank reference letter, requested by some banks
For Companies and Structures
- Certificate of incorporation, articles and register extract
- Register of shareholders and directors, plus a declaration of the beneficial owner (Form A or K)
- Trust deed or foundation charter where relevant
- Financial statements and a description of the business
Copies sent by mail must be certified, and documents issued abroad may need an apostille. Source of wealth is where most applications stall: the narrative has to be coherent and every material figure supported.
Best Banks in Switzerland
The Swiss market counts more than 235 banking institutions, from global groups to regional and cantonal banks. For international clients, the choice usually comes down to a group of private banks and one universal bank.
Pictet
Founded in Geneva in 1805 and still owned by its managing partners, Pictet is one of Europe's leading independent wealth and asset managers. Assets under management or custody reached a record CHF 757 billion at the end of 2025, with CHF 19 billion of net new money during the year.
Pictet works exclusively in wealth management, asset management, alternative investments and related services, and does not engage in investment banking or commercial lending. Its partnership structure, conservative balance sheet and long investment horizon make it a natural choice for families seeking a long-term discretionary relationship and access to in-house alternative and thematic strategies. It sits at the top of the entry scale.
