Big banks in the US post big increases in profit and revenue in 2023. Chase bank posted 52% increase in first quarter 2023 profit and record revenue. Chase attracted $50 billion in deposits from midsized banks. The problems at midsized banks, including collapse of SVB bank, have not affected the large banks. Depositors shifted deposits from midsized banks to larger banks. The Fed's sharp increase in interest rates to 4.75%-5.0% from about zero% in 2021 have increased bank margins as interest rates on deposits have not been increased as much. The glut in deposits means banks could keep depositor interest rates lower. The result is that America's banking system is in strong shape during a localized banking crisis affecting startups and Silicon Valley.
