LONDON, ENGLAND - MARCH 30: The Credit Suisse building in Canary Wharf on March 30, 2021 in London, England. A number of banks, including Credit Suisse and Nomura, have warned of significant losses to their Q1 results due to the collapse of a large US hedge fund. Credit Suisse shares fell nearly 14% and Nomura by over 16% on Monday at the news. Nomura reported a potential $2 billion loss as the US investment fund reported to be Archegos Capital Management run by billionaire Bill Hwang, was forced to liquidate more than $20 billion of assets after it defaulted on margin calls last week.
