On March 10, 2023, the Federal Deposit Insurance Corporation (the “FDIC”) issued a press release stating that Silicon Valley Bank (“SVB”) was closed by the California Department of Financial Protection and Innovation, which appointed the FDIC as receiver. In a joint statement issued by the Department of the Treasury, Board of Governors of the Federal Reserve System and Federal Deposit Insurance Corporation on March 12, 2023, the Department of Treasury took actions to enable the FDIC to complete its resolution of SVB in a manner that fully protects all depositors. According to the joint statement (the “Statement”), depositors will have access to all of their money starting Monday, March 13, 2023. On March 13, 2023, Silicon Valley Bridge Bank, N.A., the new entity formed by the FDIC announced appointment of a new CEO, who provided assurance of immediate restoration of full banking services.
