esisuisse is the deposit insurance scheme that guarantees client money held with Swiss branches of banks and securities firms. If a deposit is no longer available in the event of a bankruptcy, all clients have their savings repaid by the liquidator up to a maximum of CHF 100 000. This limit applies per client and bank.
"Are my deposits protected under the deposit insurance esisuisse? Yes, like any bank and any securities firm in Switzerland, the Cantonal Bank of Zurich is required to sign the Self-regulation “Agreement between esisuisse and its members”. This means clients’ deposits are protected up to a maximum of CHF 100,000 per client. Medium-term notes held in the name of the bearer at the issuing bank are also considered deposits. Depositor protection in Switzerland is provided by esisuisse, and the depositor protection system is explained in detail at https://www.esisuisse.ch/en".
