Cantonal Banks Switzerland: Full List & Guide (2026)

Switzerland has 24 cantonal banks — one per canton. State-owned or majority state-owned, most carry a cantonal government guarantee on deposits. They form the backbone of Swiss regional banking, providing retail accounts, mortgages, SME lending, and — increasingly — corporate banking services for internationally owned companies. This guide explains what cantonal banks are, lists all 24, and covers their relevance for foreign businesses.

Why Cantonal Banks Matter for Foreign Company Founders

Cantonal banks are the most realistic banking option for most foreign-owned Swiss companies. They are chartered under cantonal legislation, majority-owned by their respective cantonal governments, and operate primarily within their home canton. Here is what matters for account opening:

State guarantee (Staatsgarantie): Most cantonal banks carry an unlimited state guarantee from their canton — if the bank fails, the canton covers all depositor losses. This makes cantonal banks among the safest deposit institutions in the world. ZKB (Zurich) and BCGE (Geneva) have explicit state guarantees; a small number have reduced or abolished theirs.

Regional focus: Cantonal banks serve their home canton’s retail and business clients. Their primary business is mortgages, retail accounts, and SME lending — not global investment banking.

FINMA supervision: All cantonal banks are supervised by FINMA under the Swiss Banking Act, alongside all other Swiss banks.

Membership: All 24 cantonal banks are members of the Association of Swiss Cantonal Banks (VSKB/UICB).

Deposit protection: Beyond the state guarantee, cantonal banks participate in the Swiss depositor protection scheme (esisuisse), which covers up to CHF 100,000 per depositor. The Swiss National Bank (SNB) publishes annual banking statistics covering all cantonal banks.

The 24 Cantonal Banks

Key Cantonal Banks for International Business

ZKB (Zürcher Kantonalbank): The largest cantonal bank and one of Switzerland’s most important financial institutions. ZKB serves international businesses in Zurich alongside its full retail banking operation. It offers SME lending, corporate accounts, treasury services, and a private banking division. The Canton of Zurich provides an explicit, unlimited state guarantee.

Zuger Kantonalbank: The primary cantonal bank in Zug, with deep experience serving the canton’s large population of international companies and holding structures. Zuger Kantonalbank operates with lower asset thresholds than UBS — it does not require CHF 500’000+ under management to consider a new corporate client, making it substantially more accessible for smaller international structures. It is accustomed to foreign shareholders, multi-currency accounts, and the specific compliance profile of Zug’s international business community. For companies registered in Zug, this is typically the most straightforward first application.

From our experience, the Zuger Kantonalbank’s compliance process is thorough but predictable. Where UBS may take 8–12 weeks, Zuger Kantonalbank can process a well-prepared international corporate application in 4–6 weeks. The bank understands holding structures and is not alarmed by foreign shareholders — which is a genuine advantage, because many cantonal banks outside Zug and Zurich have limited experience with non-Swiss ownership and default to caution.

BCGE (Banque Cantonale de Genève): The key cantonal bank for Geneva’s international community — private clients, NGOs, international organisations, and financial sector firms. BCGE carries an explicit state guarantee from the Canton of Geneva.

Opening a Corporate Account at a Cantonal Bank

Cantonal banks are the most accessible route for foreign-owned Swiss companies to open operating accounts, because:

• Most have structured, predictable onboarding processes
• They understand Zug and Swiss company formation structures well
• They offer Kapitaleinzahlungskonten (capital deposit accounts) for company formation
• Both online and in-person options are available at most banks

Standard documentation required is similar across Swiss banks: commercial register extract, articles of association, Form A (beneficial owner declaration), passports for all UBOs, source of funds documentation, and a business description.

What cantonal banks actually check beyond the standard list: Most cantonal banks will also run all directors and UBOs through WorldCheck or equivalent AML screening databases. A flag — even a false positive from a common name — triggers enhanced due diligence. PostFinance (technically not a cantonal bank, but often grouped with them) goes further: it requires a full business plan, CVs of all directors, employment contracts, and detailed transaction descriptions. PostFinance also has a pattern of rejecting accounts for companies with brand-sensitive names or business models that do not fit neatly into their internal categories.

The practical advice: if you have a clean structure with EU/EFTA ownership and genuine substance in the canton, a cantonal bank application is straightforward. If your structure involves US persons, complex multi-jurisdictional ownership, or a business model that requires explanation, expect the compliance process to be longer and less predictable. Having a better address (a real office, not a c/o address) genuinely improves banking outcomes — banks notice.

Cantonal Banks vs. Private Banks

Cantonal banks and private banking Switzerland serve different client profiles. Cantonal banks focus on regional retail and SME banking, with the added security of state guarantees. Private banks — many based in Geneva and Zurich — focus on wealth management for high-net-worth individuals, typically requiring minimum assets and offering discretionary portfolio management. For most operating companies and SMEs, a cantonal bank is the practical choice. For personal wealth structuring alongside a Swiss company, a private bank or the private banking arm of ZKB or BCGE may be more appropriate.

Cantonal Banks vs. Other Swiss Banks: Practical Comparison

Real Rejection Patterns

Cantonal banks are more accessible than UBS, but they are not automatic approvals. From our practice:

• Brand-sensitive names: PostFinance rejected a company because “Tesla” appeared in its registered name. The bank demanded justification for the name choice.
• Health and pharma sectors: Two companies with clean documentation were rejected by PostFinance without clear explanation.
• US nexus: Nearly all cantonal banks lack FATCA infrastructure and will decline companies with US beneficial owners.
• Address quality: Companies using a c/o address rather than a direct registered address face higher scrutiny. Banks notice the difference.

The 80% conversion signal applies here: if a cantonal bank approves your capital deposit account during formation, approximately 80% of those relationships convert into permanent corporate accounts.

Frequently Asked Questions

What are cantonal banks in Switzerland? Cantonal banks (Kantonalbanken) are banks chartered under cantonal legislation and majority-owned by a Swiss cantonal government. There are 24 of them — one per canton, with Appenzell Innerrhoden served by St. Galler Kantonalbank. They focus primarily on retail banking, mortgages, and SME lending within their home canton.

How many cantonal banks are there in Switzerland? There are 24 cantonal banks in Switzerland, all members of the Association of Swiss Cantonal Banks (VSKB/UICB). Each is tied to its home canton and majority-owned by the cantonal government.

What is the state guarantee on cantonal banks? The state guarantee (Staatsgarantie) means the cantonal government backstops all depositor losses if the bank were to fail. Most cantonal banks carry this unlimited guarantee. Notable examples with explicit guarantees include ZKB (Zurich) and BCGE (Geneva). A small number of cantonal banks have reduced or removed their guarantee — check the specific bank’s terms.

Which is the largest cantonal bank in Switzerland? Zürcher Kantonalbank (ZKB) is the largest cantonal bank and one of Switzerland’s most significant banks overall. It is wholly owned by the Canton of Zurich, carries an explicit state guarantee, and offers retail banking, SME lending, corporate accounts, wealth management, and treasury services.

Are cantonal banks supervised by FINMA? Yes. All cantonal banks are supervised by FINMA under the Swiss Banking Act, exactly like any other Swiss bank. Supervision covers capital adequacy, liquidity, AML compliance, and conduct standards.

How do cantonal banks differ from UBS or other private banks? Cantonal banks are state-owned, regionally focused, and carry (in most cases) a government guarantee. UBS and other large private banks are traded on stock exchanges, operate globally, and have no state guarantee. Cantonal banks generally offer more accessible corporate onboarding for Switzerland-based businesses and stronger deposit safety, but do not offer the global investment banking services of the large universal banks.

Can a foreign-owned company open an account at a cantonal bank? Yes. Many cantonal banks open accounts for foreign-owned Swiss companies. Zuger Kantonalbank, ZKB, and BCGE are the most experienced with international shareholders and holding structures. Required documents include a commercial register extract, articles of association, beneficial owner declaration (Form A), passports for all UBOs, source of funds documentation, and a business description.

Which cantonal bank is best for a Zug company? Zuger Kantonalbank (ZugerKB) is the natural first choice for companies registered in Zug. Unlike UBS, which requires CHF 500’000+ under management for new non-resident clients, Zuger Kantonalbank operates with lower thresholds and is more accessible for smaller international structures. It has extensive experience with international holding structures, foreign shareholders, and multi-currency accounts — reflecting Zug’s status as Switzerland’s primary corporate hub.

Do cantonal banks offer capital deposit accounts for company formation? Yes. Most cantonal banks offer a Kapitaleinzahlungskonto (capital deposit account), required during Swiss company formation to deposit share capital before registration. Once the commercial register confirms incorporation, the account converts to a standard business account.

Are cantonal banks a good option for private banking? Some cantonal banks have private banking divisions — notably ZKB, BCGE, and BCV (Vaud). For high-net-worth individuals seeking full discretionary private banking, dedicated private banks often provide a broader international offering. Cantonal banks are generally stronger for domestic wealth management and regional investment products.
