Why was the bank run of 1930 happened?

The bank run of 1930 occurred due to widespread panic among depositors during the early years of the Great Depression. As businesses failed and unemployment rose, people lost confidence in the banking system, leading to massive withdrawals of savings. Many banks, unable to meet these withdrawal demands, faced insolvency, which further fueled the panic and resulted in a cascade of bank failures across the United States. This event highlighted the vulnerabilities of the banking system and contributed to the need for reforms in financial regulation.
