First Republic has been under great pressure since the close bankruptcies of two banks with a similar profile in early March. Many customers had withdrawn deposits in the first quarter, more than $ 100 billion in total.

Between four and six of them are expected to do so, the source told AFP. The FDIC would initially take control of First Republic, according to several US media. The deal could be announced early Monday to avoid too much disruption for First Republic's customers, CNBC reported. The bank said it had no comment.
