After the collapse and bail out of Silicon Valley Bank and Signature Bank, the U.S. banking market is not settling. U.S. regulators have requested that banks submit their best takeover offers for First Republic by Sunday afternoon. The U.S. Federal Deposit Insurance Corporation has reportedly asked six banks to bid for the embattled lender. Shares in First Republic plunged from $122.50 on March 1 to around $3 a share last Friday.
