Swiss bank UBS is investigating undisclosed Nazi-linked accounts at Credit Suisse, following a report that some accounts had not been disclosed in earlier investigations. UBS is working with an independent ombudsman to shed light on the issue and address the legacy of Nazi-linked accounts held at predecessor banks of Credit Suisse. The ombudsman's probe uncovered client files marked 'American blacklist' and revealed signs of a cover-up during past reviews. A final report is expected to be issued by early 2026.
