Overview
This series separates a depositor withdrawal wave from permanent bank failure, then traces how liquidity, fundamentals, depositor concentration, insurance, and institutional response shape whether pressure is contained, damages a surviving bank, or interrupts local credit and production. Historical evidence from U.S. banks, 1863–1934, is paired with account-level evidence from three failed banks in 2023; the comparisons clarify mechanisms but do not provide universal forecasts.
Learning outcomes
- A bank run is a withdrawal episode; bank failure is a permanent institutional outcome, so one does not automatically imply the other.
- Weak capital, liquidity, and fragile funding make a run more likely to pass through into failure, while public signals can also pull strong banks into a run.
- Liquidity, support, credible information, examination, temporary suspension, and insurance can interrupt the path, but survival may still leave lasting funding or lending losses.
- Historical local damage was more severe when runs involved weak banks or failure; 2023 shows that concentration and wire speed compress response time.

PlansFAQ
What is the difference between a bank run and bank failure?
A bank run is a sudden wave of depositor withdrawals, while bank failure is a permanent suspension in which the institution no longer operates as an intermediary. A run can end in containment, temporary suspension and reopening, or failure.
Why does a bank run lead to failure for some banks but not others?
A run is more likely to lead to failure when the bank begins with weak capital, limited liquidity, fragile funding, or little time and support to absorb withdrawals. Public news can trigger runs at strong banks, which may survive through liquidity, information, or coordinated response.
How can a bank survive a run?
A bank can survive a run by meeting withdrawals, obtaining interbank or owner funding, making its condition credible, receiving examination or coordination, or suspending temporarily and reopening. These measures buy cash, information, or time, but may leave lasting deposit and loan losses.
When does a bank run become an economic shock?
A run becomes a broader economic shock when weak-bank funding losses or failure interrupt local credit and production beyond the immediate withdrawal episode. Historical evidence links larger declines in city deposits, lending, and manufacturing to weak fundamentals or failure, while common downturns may also contribute.
