Introduction

Imagine hearing a rumor that your bank is in trouble. You rush to withdraw your money, and so does everyone else. Even a healthy bank can collapse under that pressure. This is called a bank run.

Why Bank Runs Happen

Banks lend out most of the money customers deposit, keeping only a portion on hand. That works fine as long as people do not all withdraw at once. If fear spreads, customers may race to pull out their money, and the bank may not have enough cash available.

Famous Bank Runs

During the Great Depression, thousands of U.S. banks failed due to runs. In 2023, Silicon Valley Bank collapsed after customers tried to withdraw about $42 billion in a single day, fueled by fears spreading quickly on social media. It was one of the fastest bank runs in history.

How Runs Are Prevented

Deposit insurance from the FDIC protects deposits up to $250,000 per account category, so most people have no reason to panic. Central banks can lend emergency money to banks. Regulators also require banks to hold enough capital and liquid assets to handle withdrawals.

Conclusion

Bank runs show how important trust is in the financial system. Thanks to safeguards like deposit insurance, most people's money is much safer today!
