Credit Suisse said Christian Meissner, who ran investment banking at Bank of America before joining the Swiss lender last year, would be appointed chief of the investment bank from May 1. Joachim Oechslin will resume on an interim basis the role of chief risk officer, which he held until February 2019, while Thomas Grotzer will become interim global head of compliance. Warner and Chin are paying the price for a year in which Credit Suisse's risk management protocols have come under harsh scrutiny.
