Shares of the regional bank are down 60% in the premarket. The lender said in a statement late Sunday that it had more than $70 billion in unused liquidity to fund operations from agreements that included the Federal Reserve and JPMorgan Chase & Co.

"The additional borrowing capacity from the Federal Reserve, continued access to funding through the Federal Home Loan Bank, and ability to access additional financing through JPMorgan Chase & Co. increases, diversifies, and further strengthens First Republic's existing liquidity profile," the bank said, adding that more liquidity is available through the Fed's new lending facility. 

"The plunge in its shares is classic market psychology at work, with investors starting to question the credentials of any lender that may be remotely in the same category of Silicon Valley Bank," Bloomberg's Ven Ram wrote. 

We pointed out over the weekend, "as a result of the SVB failure - one look at what is already taking place at some smaller, vulnerable banks such as this First Republic Branch in Brentwood should be sufficient to see what comes tomorrow if the Fed makes the wrong decision today."
