Summary List PlacementCredit Suisse has seen a massive exodus of bankers, traders, and other senior staff in recent months. Now, the bank is starting to replace some of them. Credit Suisse has been caught up in a series of problems over the last two years, most recently dealing with the fallout from the implosion of Archegos Capital Management, a family-office client founded by a hedge-fund billionaire that had $8 billion in assets wiped out when massive, concentrated bets held in swaps positions moved against it.
