Banks and the Money Supply: An Example
Suppose $100 of currency is in circulation.
To determine banks’ impact on money supply, we calculate the money supply in 3 different cases:
1. No banking system
2. 100% reserve banking system: banks hold 100% of deposits as reserves, make no loans
3. Fractional reserve banking system

Bank Runs and the Money Supply
During 1929-1933, a wave of bank runs and bank closings caused money supply to fall 28%.
Many economists believe this contributed to the severity of the Great Depression.
Since then, federal deposit insurance has helped prevent bank runs in the U.S.
In the U.K., though, Northern Rock bank experienced a classic bank run in 2007 and was eventually taken over by the British government.
