How did black Tuesday affect the banks?

Black Tuesday, which occurred on October 29, 1929, marked the Stock Market crash that precipitated the Great Depression. As stock prices plummeted, banks faced massive withdrawals as depositors rushed to retrieve their savings, leading to liquidity crises. Many banks had invested heavily in the stock market, and the crash resulted in significant losses, causing numerous banks to fail. This loss of confidence further exacerbated the banking crisis, leading to a wave of bank closures and a tightening of credit.
