Bank Cler: Swiss retail bank account
Marcus Altenburg, Published
Bank Cler is a retail bank based in Basel, founded in 1927. It works with international clients, so a non-resident can open an account here when the source-of-funds file is clean. As a retail bank, it typically expects little or nothing for residents, though non-resident access is limited — as of July 2026, and not a published per-bank figure.

Can a non-resident open an account at Bank Cler?
Yes. Bank Cler assesses each non-resident applicant on source of wealth, source of funds and risk profile. The decisive factor is a documented source of funds, not nationality. Assemble the evidence (tax returns, sale or employment records, a clear paper trail) before you approach the bank.
How to open an account at Bank Cler
- Confirm your profile and the account type. Agree the type of relationship — personal, private-banking or corporate — and the likely minimum with a relationship manager.
- Assemble the documents. A valid passport, proof of address dated within three months, and evidence of the source of your funds and wealth (full checklist below).
- Verify your identity. Residents can usually start online or in a branch; a non-resident normally attends one in-person meeting at a Swiss office.
- Compliance review, then go-live. The bank runs its onboarding, AML and source-of-funds checks, then opens the account and issues access. Expect case by case once the file is complete.
Requirements: resident vs non-resident
| Requirement | Swiss resident | Non-resident |
|---|---|---|
| Typical minimum | Little or none | Limited / case by case |
| Identification | Branch visit | Branch visit, where accepted at all |
| Indicative timeline | one to two weeks | case by case |
| Remote opening | Sometimes | Rarely — usually one Swiss visit |
Documents you will need
- a valid passport or national identity card;
- proof of residential address dated within the last three months (utility bill, bank statement or official letter);
- evidence of the source of funds and source of wealth (tax returns, employment or sale contracts, business records, inheritance documents);
- a FATCA/CRS self-certification, plus beneficial-ownership declarations where a company or structure holds the account.
How your money is protected
Deposits at Bank Cler, as at every Swiss bank, are covered by the Swiss depositor-protection scheme (esisuisse) up to CHF 100,000 per client, per bank. Securities held in custody remain the client's property and are segregated from the bank's own balance sheet, so they are returned in full even if the bank fails. Bank Cler is supervised by FINMA, and reports a capital ratio of 26–27% risk-adjusted capital (S&P projection through 2027).
Is Bank Cler a fit for a non-resident?
As a retail bank, Bank Cler is built around customers resident in Switzerland. A non-resident without a Swiss footing will usually find a private or online bank the more realistic route.
