PacWest Bank's Shares Plummet 30% Amid Deposit Withdrawals.

Shares of PacWest Bancorp fell 30% after the bank reported that customers had withdrawn about 9.5% of total deposits, prompting the bank to pledge more of its assets as collateral to shore up its cash position. PacWest is one of several mid-size lenders that has been under intense scrutiny since Silicon Valley Bank collapsed on March 10, setting off a panic around the financial stability of similarly positioned banks.
