The Stock Market Crash of 1929: 5 Things You Should Know

Question: In the 1920s, stock prices soared as a growing number of Americans rushed to invest. Why did so many people suddenly buy stocks?

Answer: The 1920s boom turned stock buying into a national craze fueled by optimism. Many people bought because prices kept rising, not because companies were truly worth more.

Question: Many 1920s investors paid just 10% of a stock’s price and borrowed the rest. Why did this habit make the crash so much worse?

Answer: Buying “on margin” let people control big investments with little cash, but it multiplied their losses. When prices dropped, lenders demanded repayment, which forced even more selling.

Question: After the crash, thousands of U.S. banks failed in the early 1930s. Why did people who never owned stock lose their savings?

Answer: Panicked customers rushed to withdraw cash, and banks that ran out simply closed. With no deposit insurance, families lost everything they had saved.

Question: During the Great Depression, about 1 in 4 American workers had no job. How did a stock crash cost so many people their jobs?

Answer: With savings gone and confidence shattered, spending dried up and businesses laid off millions. The crash didn’t cause the Great Depression alone, but it set off a chain reaction across the economy.

Question: In 1934, Congress created the SEC, a new agency to watch over Wall Street. What problem was the agency meant to fix?

Answer: The crash exposed a market full of rumors, hidden risks, and misleading claims. The SEC still requires companies to share honest financial information with the public.
