First Republic reported a more than $100 billion plunge in deposits in the quarter in the aftermath of the biggest turmoil to hit the banking sector since 2008. Regional bank PacWest Bancorp (PACW.O) fell 9%, Western Alliance Bancorporation (WAL.N) 6%, Zions Bancorp (ZION.O) 5% and brokerage Charles Schwab Corp (SCHW.N) was down 4%. First Republic said on Monday it was "pursuing strategic options" to quickly strengthen the bank, without providing details. Options include an asset sale of up to $100 billion, a source familiar with the situation said on Tuesday. "So it's tough to even describe it as good asset and bad asset," Chiaverini said.
