The biggest bank in Switzerland is UBS — by a very wide margin, and even more so since it absorbed Credit Suisse in 2023. Below UBS, though, the ranking of the largest Swiss banks depends on which yardstick you use. By balance-sheet size, the cooperative Raiffeisen group and the cantonal banks dominate. By client assets under management, the Geneva and Zurich private banks — Pictet, Julius Baer, Lombard Odier — rank far higher than their modest balance sheets would suggest. This page gives both rankings, explains the difference, and links to the full profile of each institution in the Swiss banks directory.
Figures are rounded and drawn from the banks' most recent published annual reports; they move with markets and exchange rates, so treat them as orders of magnitude rather than precise league-table positions.
Top 10 Swiss banks by total assets
Total assets (the balance sheet) is the standard measure for ranking banks by size. It captures lending and deposits — which is why domestically focused retail lenders such as Raiffeisen and the cantonal banks appear near the top, even though they are little known outside Switzerland.
| # | Bank | Type | Total assets (approx.) | Known for |
|---|---|---|---|---|
| 1 | UBS Group | Universal, G-SIB | CHF 1.7 trillion | World's largest wealth manager; the only Swiss global systemically important bank |
| 2 | Raiffeisen Switzerland | Cooperative group | CHF 280–300 billion | Largest domestic retail and mortgage lender; 800+ branches |
| 3 | Zürcher Kantonalbank (ZKB) | Cantonal | CHF 210 billion | Largest cantonal bank; unlimited state guarantee; AAA-rated |
| 4 | PostFinance | State-owned | CHF 120 billion | Payments and everyday banking for 2.7 million customers |
| 5 | Julius Baer | Private bank | CHF 100 billion | Largest pure-play Swiss private bank |
| 6 | Luzerner Kantonalbank | Cantonal | CHF 60 billion | Central-Swiss cantonal bank with a state guarantee |
| 7 | Banque Cantonale Vaudoise (BCV) | Cantonal | CHF 58 billion | Dominant bank in Canton Vaud; listed on the SIX exchange |
| 8 | Migros Bank | Retail | CHF 52 billion | Cooperative-owned retail bank with a "fair banking" positioning |
| 9 | Pictet Group | Private bank | CHF 45 billion | Partnership since 1805; far larger by client assets than by balance sheet |
| 10 | Banque Cantonale de Genève (BCGE) | Cantonal | CHF 32 billion | Geneva's cantonal bank with an unusually international client book |
Positions 6 to 10 are close together and swap around from year to year; several other cantonal banks (St. Gallen, Aargau, Basel-Landschaft, Berne) and the Swiss arms of foreign groups sit just outside this list. Before 2023, Credit Suisse would have been a clear second; its balance sheet is now part of UBS.
Top Swiss banks by assets under management
For an international client, balance-sheet size is often the wrong question. What matters for wealth management is client assets under management (AUM) — and on that measure the picture changes substantially.
| # | Bank | Client assets / AUM (approx.) | Profile |
|---|---|---|---|
| 1 | UBS | CHF 5.5 trillion invested assets | Global wealth manager, asset manager and investment bank |
| 2 | Pictet | CHF 630 billion | Wealth and asset management; no investment banking |
| 3 | Julius Baer | CHF 470 billion | Listed pure-play private bank |
| 4 | Zürcher Kantonalbank | CHF 450 billion | Cantonal bank with a large asset-management arm (Swisscanto) |
| 5 | Lombard Odier | CHF 290 billion | Geneva partnership founded 1796 |
| 6 | Vontobel | CHF 280 billion | Zurich wealth and asset manager, listed |
| 7 | Raiffeisen Switzerland | CHF 250 billion | Mostly domestic retail client assets |
| 8 | EFG International | CHF 160 billion | Zurich-based, internationally diversified private bank |
| 9 | Union Bancaire Privée (UBP) | CHF 150 billion | Family-controlled Geneva private bank |
| 10 | Edmond de Rothschild (Suisse) | CHF 100 billion | Family-owned Geneva private bank |
A dedicated comparison of the wealth-management houses in this table — including minimum deposits for foreign clients and which ones accept U.S. persons — is on the Swiss private banks page.
Why the two rankings differ so much
A retail or cantonal bank takes deposits and makes mortgages, so its business shows up on its own balance sheet. A private bank holds client securities in custody, off its balance sheet — a bank with CHF 600 billion of client portfolios may have a balance sheet of only CHF 40–50 billion. Neither number is "wrong"; they describe different businesses.
- If you want a lender or a deposit-taker (mortgage, current account, large cash balances), the total-assets ranking is the relevant one, together with the bank's capital ratio and any cantonal guarantee.
- If you want a wealth manager, AUM signals scale of research, custody infrastructure and negotiating power with fund houses — but beyond a certain size, service quality has more to do with the team than the league-table position.
The biggest bank in Switzerland: UBS in context
UBS is not just the largest Swiss bank; after the 2023 acquisition of Credit Suisse its balance sheet is roughly twice the size of Swiss GDP. That scale is why the Swiss "Too Big to Fail" rules impose additional capital, liquidity and resolvability requirements on it, and why the post-2023 debate about further capital surcharges matters to the whole Swiss financial centre. For clients, UBS's size brings global reach and product depth; it also brings the most standardised onboarding and the least flexibility on minimums — see the account-opening guide for what that means in practice.
How many banks are there in Switzerland?
Around 230 banks hold a FINMA licence. The Swiss National Bank groups them into: the big bank (UBS), 24 cantonal banks, Raiffeisen, regional and savings banks, stock-exchange and private banks, foreign-controlled banks and branches of foreign banks, and a small "other" category that includes the digital and crypto-focused newcomers. Roughly a third of Swiss banks are foreign-controlled. The directory profiles the institutions in each group that are most relevant to international clients.
Largest Swiss banks by category
- Largest universal bank: UBS (the only one left in the category).
- Largest cantonal bank: Zürcher Kantonalbank, followed by BCV, Luzerner Kantonalbank and BCGE.
- Largest cooperative: Raiffeisen Switzerland, a group of around 220 locally owned member banks.
- Largest private bank: Pictet by client assets; Julius Baer by balance sheet and as a listed company.
- Largest foreign bank in Switzerland: the Swiss private-banking arms of HSBC, J.P. Morgan and BNP Paribas are the most substantial — see foreign banks in Switzerland.
- Largest digital bank: by user numbers, Neon and Yuh lead the Swiss app-based accounts, but they are tiny in balance-sheet terms and mostly serve Swiss residents.
Does bigger mean safer?
Not automatically. All FINMA-licensed banks are members of esisuisse, and privileged deposits are protected up to CHF 100,000 per depositor per bank regardless of the bank's size. Above that figure, the relevant questions are the bank's capitalisation, whether a canton stands behind it, and how a resolution would be structured — all covered on the Swiss deposit protection page. Several of the best-capitalised institutions in Switzerland are mid-sized cantonal banks with explicit state guarantees, not the largest names.
Choosing between the top Swiss banks
For most international readers the shortlist comes down to a handful of decisions: whether you need lending as well as custody, whether you are a U.S. person (which rules out several private banks), how much you plan to deposit, and whether you prefer a listed group or a partnership. The bank finder tool runs those filters against the directory, and the complete Swiss banking guide covers the regulatory background that applies to every bank on this page.
