A cantonal bank's state guarantee covers all of its liabilities: if the bank can no longer meet them, its canton is liable for them. According to the "Banque cantonale" article in the online encyclopaedia Wikipedia, consulted in October 2026, 21 of the 24 cantonal banks benefit from this full guarantee. Banque Cantonale Vaudoise, Berner Kantonalbank and Banque Cantonale de Genève do not have it. This protection goes further than the deposit insurance provided by esisuisse, the self-regulatory organisation of Swiss banks, which is capped at 100,000 francs per client and per bank.
This page deals only with the question of client protection. An overall portrait of the sector, including its weight and its clientele, can be found on our page on the cantonal bank. Other banking topics are gathered in the Banks and FINMA section.
What does a cantonal bank's state guarantee cover?
The state guarantee applies to all of the bank's liabilities, not just to client accounts. Wikipedia describes it as a "guarantor's liability" of the canton concerned. The canton is thus subsidiarily liable for all of its bank's liabilities.
Subsidiarily means that the canton only steps in second. The bank is first liable for its debts with its own resources. The canton takes over if these resources are not sufficient.
The guarantee is described as full: the source mentions no cap per client or per type of claim. Nor does it specify the procedure, or the time frame within which a canton would have to pay.
Which cantonal banks benefit from it, and which do not?
Twenty-one cantonal banks out of twenty-four benefit from their canton's full guarantee, according to Wikipedia. This is the case, for example, of Zürcher Kantonalbank, the cantonal bank of Zurich and the largest in the group.
Three institutions have no state guarantee at all. The table shows their 2022 total assets, taken from the list published by Wikipedia based on figures from the Association of Swiss Cantonal Banks (VSKB).
| Bank without a state guarantee | Founded | Total assets 2022 |
|---|---|---|
| Banque Cantonale Vaudoise | 1845 | 59.4 billion francs |
| Berner Kantonalbank | 1834 | 39.8 billion francs |
| Banque Cantonale de Genève | 1816 | 30 billion francs |
For clients of these three banks, protection relies on deposit insurance, as it does for clients of any bank established in Switzerland. The sources consulted do not explain why these cantons do not grant a guarantee.
Who pays for the state guarantee?
The bank itself pays its canton for this guarantee. According to Wikipedia, it pays the canton financial compensation, set by cantonal regulations.
The amount of this compensation is not given by the source. The sources consulted make it possible neither to quantify these compensation payments nor to compare them.
How does it differ from esisuisse deposit insurance?
Deposit insurance protects only clients' assets, and only up to a cap. According to esisuisse, it protects clients' deposits from loss up to 100,000 francs if a bank goes bankrupt. The cap applies per client and per bank.
esisuisse is a private association based in Basel, the self-regulatory organisation of Swiss banks and securities firms. All banks with a branch in Switzerland must be members. Cantonal banks, whether or not they are guaranteed by their canton, are therefore subject to it like all the others.
According to esisuisse, the guarantee protects all clients, private individuals and companies alike. It is regulated by law. esisuisse finances the payout of guaranteed deposits if the liquidity of the bankrupt bank is not sufficient. A partial revision of the Banking Act, in force since 1 January 2023, strengthened depositor protection, particularly for holders of joint accounts.
| Criterion | State guarantee | Deposit insurance |
|---|---|---|
| Guarantor | The canton, on a subsidiary basis | esisuisse, a private self-regulatory association |
| Banks concerned | 21 of the 24 cantonal banks | All banks with a branch in Switzerland |
| What is covered | All of the bank's liabilities | Client deposits, private and corporate |
| Cap | None mentioned: described as a full guarantee | 100,000 francs per client and per bank |
| Basis | Cantonal regulations | The Banking Act |
| Consideration | Compensation paid by the bank to the canton | Not specified by the source |
An institution holding a FinTech licence offers neither. According to esisuisse, its clients' deposits are neither privileged nor protected by deposit insurance in the event of bankruptcy. 2clics covered this in detail in its article "Swiss neobank: licence, deposit insurance and differences".
Is the state guarantee being called into question?
It is under discussion in the context of relations with the European Union (EU). According to Wikipedia, the negotiations between Switzerland and the EU on Swiss banks' access to the European market call this guarantee into question. The encyclopaedia relies on an article in the NZZ am Sonntag of 14 February 2016.
The sources consulted do not say where this matter stands in 2026. On the deposit insurance side, the VSKB defends the status quo. In its "Session Review" of 2 September 2026, it considers that the current system has proven its worth and rejects any adjustment.
History shows that a cantonal bank can disappear. According to Wikipedia, those of Solothurn and Appenzell Ausserrhoden disappeared in the mid-1990s, following economic difficulties and mismanagement. The Solothurn bank was integrated into Swiss Bank Corporation on 1 January 1995. The takeover of the Appenzell bank by UBS was decided in 1996. The source does not say what role the state guarantee played in these two cases.

- 100,000 francs: cap on deposit insurance, per client and per bank (esisuisse).
- 1 January 2023: entry into force of the partial revision of the Banking Act on depositor protection.

What it means for a saver or an SME
For a client, the first question is which guarantee applies to their bank. At 21 cantonal banks, the canton is liable for all liabilities, beyond the deposit insurance cap. At the other three, only deposit insurance applies, up to 100,000 francs per client.
For an SME, esisuisse specifies that companies are protected in the same way as private individuals, with the same cap. Beyond that, only the state guarantee, where it exists, covers the balance. The exact status can be checked with the bank, whose guarantee is set by cantonal regulations. This page does not constitute financial advice.
