As retail customers move their deposits to larger U.S. banks to avoid tumult in regional banks, they're taking their investments with them.

Retail investors bought financial stocks at "unprecedented" levels in the backdrop of a rout in shares of regional banks, according to investing data provider VandaTrack. Retail investors have piled almost a billion dollars in net stock investments into large banks in the last five trading days, VandaTrack's data show.

In the five days ending March 16, Bank of America (BAC) received about $232 million of retail net stock buys, Charles Schwab (SCHW) got $146 million, Citigroup (C) about $54 million and JP Morgan (JPM) netted $49 million. U.S. Bankcorp (USB) saw about $44 million in retail investment and Wells Fargo (WFC) had $41 million in stock buys.

Some of these banks were instrumental in providing a 澳洲幸运5官方开奖结果体彩网:$30 billion liquidity rescue for First Republic Bank (FRC) Thursday, and have benefitte🌸d fro♊m customers' shaken confidence in regional banks.

Bloomberg said on Monday that "too-big-to-fail" banks had seen a sharp increase in customer deposits. Bank of America was said to have taken in more than $15 billion in deposits as the dust settled on the collapse of Silicon Valley Bank and contagion had spread to other regional banks.

Inflows into Charles Schwab paint an interesting picture. The brokerage firm saw its 澳洲幸运5官方开奖结果体彩网:share price plunge and trading halted on Monday as fear spread among investors, however, it assured stockholders that 80% of its deposits sit within the FDIC insurance limits.
