SANTA CLARA, CALIFORNIA – MARCH 10: A sign is posted in front of the Silicon Valley Bank (SVB) headquarters on March 10, 2023 in Santa Clara, California. Silicon Valley Bank was shut down on Friday morning by California regulators and was put in control of the U.S. Federal Deposit Insurance Corporation. Prior to being shut down by regulators, shares of SVB were halted Friday morning after falling more than 60% in premarket trading following a 60% declined on Thursday when the bank sold off a portfolio of US Treasuries and $1.75 billion in shares to cover declining customer deposits.
