Deposit insurance ended US bank runs by making the panic pointless
After about 9,000 banks suspended in four years, the 1933 Banking Act created the FDIC; insured deposits up to $2,500 and runs lost their logic.

the move
From 1930 to 1933 roughly 9,000 U.S. banks suspended operations, and the panic peaked in the first days of March 1933, forcing a nationwide bank holiday. Congress had been considering deposit insurance since 1886 — about 150 proposals — but banks and Treasury officials had long blocked it.
The Banking Act of 1933, signed by President Roosevelt on 16 June 1933, created the FDIC over the opposition of the Treasury Secretary and parts of the banking industry. A temporary fund began insuring deposits on 1 January 1934, covering up to $2,500 per depositor and guaranteeing about $11 billion in deposits; the Banking Act of 1935 made the system permanent.
The mechanism worked by removing the reason to run: once deposits were insured, a bank's rumored trouble no longer endangered your own money, so the rush to withdraw lost its point. Insured depositors received the first claim payments within months of the fund starting, and deposit insurance became the bedrock of U.S. banking stability.
why it works
- Insurance removes the first-mover advantage that makes runs rational.
- A national, government-backed fund is credible in a way private pools never were.
- Covering ordinary depositors targeted exactly the people who panic.
what transfers
If the problem is a self-fulfilling panic, fight the expectation rather than each panic: a credible backstop changes behavior before the crisis starts.
what came after
The FDIC survived the savings-and-loan crisis of the 1980s and now insures deposits up to $250,000; explicit deposit insurance has been copied by dozens of countries and is a standard pillar of financial safety nets.
