The Swiss Financial Market Supervisory Authority (FINMA) has launched an investigation into the final months of Credit Suisse prior to its acquisition by UBS in 2023. The audit aims to scrutinize the bank's handling of events leading to its downfall. This investigation covers the last 15 months of Credit Suisse as an independent entity, according to a report by SonntagsZeitung. The move comes as part of FINMA's efforts to understand the circumstances that necessitated the rescue of Credit Suisse by UBS.
