New EU banking rule could affect Swiss banks’ European customers

Swiss banks face a change to their European customer business in just over two months. A new EU banking rule is scheduled to take effect on January 11, 2027, restricting European customers’ access to Swiss banks. The reported impact is direct for institutions that serve clients across the border: from 2027, they will no longer be allowed to offer services to new EU customers. The deadline puts the rule on the near-term agenda for Swiss financial institutions with European clientele.

The rule is due to begin on January 11, 2027. The Local published its report on November 3, 2026, leaving the scheduled start date close on the calendar for banks serving customers in Europe. The date matters because the change affects what Swiss banks can offer to new EU customers from 2027. For institutions with business across the border, the rule’s start marks a shift in the conditions for taking on that customer group.

The stated restriction concerns new EU customers. From 2027, Swiss banks will no longer be allowed to offer services to this group under the rule described in the report. The change is also framed more broadly as a restriction on European customers’ access to Swiss banks. That distinction puts customer access and the ability of Swiss institutions to serve clients across the border at the centre of the issue.

Swiss financial institutions serving clients across the border will have to account for the new restriction. The rule is scheduled to take effect on January 11, 2027, and bars Swiss banks from offering services to new EU customers from 2027. Its practical significance for Swiss banks lies in that limit on serving European clients. The change places cross-border customer access in focus as the effective date approaches.
