Credit Suisse was forced to suspend $10bn of investor funds after the collapse of the supply-chain lender Greensill Capital, whose loans were packaged and sold to Credit Suisse clients. The Greensill scandal, which stemmed from risky loans it extended to companies owned by the metals magnate Sanjeev Gupta, spiralled after it emerged the former UK prime minister David Cameron lobbied ministers and government officials on its behalf. The bank is still trying to claw back money for clients and said “actions have been taken against a number of individuals” in relation to the case.
