Credit Suisse’s new chairman signalled a broad re-evaluation of the bank’s risk taking and said strategic changes could be in store after it was flung into turmoil by the back-to-back collapses of Archegos Capital Management and Greensill Capital.

Antonio Horta-Osorio, voted into the job by Credit Suisse shareholders Friday, said the bank’s current and potential risks “need to be a matter of immediate and close scrutiny,” after losing $5.5bn from the implosion of hedge fund Archegos and entangling itself with the now-insolvent finance firm Greensill. Horta-Osorio spent 11 years as chief executive at Lloyds Banking Group, which he also joined at a crisis point.
