If a bank protected by the FDIC (Federal Deposit Insurance Corporation) fails, then all of the individuals who have deposited money into the bank will be reimbursed by the federal government.
The FDIC is an independent agency of the federal government that provides deposit insurance to protect depositors in case a bank or savings institution fails. The standard deposit insurance amount is $250,000 per depositor, per insured bank, for each account ownership category.
If a bank fails and is unable to return deposits to its customers, the FDIC steps in to pay depositors up to the insured amount. This means that the individuals who have deposited money into the bank will not lose their money, as long as it is within the insured amount.
