A ‘bank run’ is a panic situation when the deposit holders start withdrawing cash from the banks.
A bank run occurs when a large number of customers withdraw their money from a bank simultaneously because they lose confidence in the bank’s solvency and fear they will lose their deposits if the bank fails.
Bank runs can lead to the bank’s collapse, even if it was initially solvent, because banks operate on a fractional reserve system and do not keep all deposits in cash. Such events can trigger financial crises. Deposit insurance and central bank lender-of-last-resort facilities are mechanisms used to prevent bank runs.
