This was primarily due to the bank’s failures that arose with the Great Depression. People lost so much of their deposited money because the banks provided loans to the many non reliable consumers.
FDIC now ensures that if something happens from bank’s side, the banks are required to keep a certain amount of amount as their reserve amount so that they can give money to its consumers when they required withdrawing.
