Credit Suisse receives $54 billion lifeline from Swiss National Bank.

Credit Suisse's shares rose by 30% after announcing it will borrow up to $54 billion from the Swiss central bank to shore up its finances. The move comes after the bank's biggest shareholder said it would not put more money into Credit Suisse, causing shares to plunge by 30%. The European bank shares recovered slightly on Thursday, with the Euro Stoxx Banks index up 1.6% following an 8.4% drop on Wednesday. Credit Suisse has been beset by problems long before the US bank failures, including bad bets on hedge funds, repeated shake-ups of its top management, and a spying scandal involving Zurich rival UBS.
