Why did Franklin Roosevelt declare a banking holiday?

Franklin Roosevelt declared a banking holiday in March 1933 to address the financial crisis during the Great Depression, which had led to widespread bank failures and public panic. The holiday temporarily closed all banks to prevent further runs on financial institutions, allowing time for the government to stabilize the banking system. Roosevelt aimed to restore public confidence in banks by implementing reforms and ensuring that only financially sound banks would reopen. This decisive action was part of his broader strategy to revitalize the economy and protect depositors' savings.
