Northern Rock bank run (2007)
British mortgage lender Northern Rock sought emergency support from the Bank of England after wholesale funding dried up. Depositors queued outside branches in the first run on a British bank since 1866.
The government guaranteed deposits to stop the run and later nationalized the bank.
The episode reshaped UK deposit insurance and bank resolution rules.
It shows how fast a lender can fail once depositors lose confidence, and why the speed of a deposit guarantee matters.
