The head of Switzerland's financial regulator FINMA questioned Credit Suisse over risks in its dealings with now-insolvent finance firm Greensill Capital "months" before the bank was forced to close $10 billion of funds liked to Greensill, Swiss newspaper SonntagsZeitung reported Sunday. Alongside formal discussions on a technical level between the bank and FINMA, the watchdog's head Mark Branson personally discussed the risks with outgoing Credit Suisse Chairman Urs Rohner and Chief Executive Thomas Gottstein during a meeting on an unspecified date, the paper reported, citing information it had obtained. FINMA declined to comment.
