What did roosevelt try to persuade people to do during the banking crisis of 1933?

Though state banks had forced their governors to declare state-wide bank holidays in response to President Hoover’s inaction, making it near-impossible for Roosevelt to do anything other than issue a federal mandate, he was able to move quickly to prevent any extreme damage to the banking system or federal finances, and to prevent a wholesale loss of public faith in the American economy.
