The Wall Street crash of 1929 began after years of industrial expansion and rapidly rising stock prices. During the “Roaring Twenties,” many Americans invested their savings, often borrowing money to buy shares. Yet agriculture was depressed, consumer purchasing power was weak, and industrial production was slowing.
After the market peaked on September 3, 1929, experienced investors began selling. Panic intensified on Black Thursday, October 24, when 12.9 million shares changed hands, and reached a peak on Black Tuesday, October 29, when 16.4 million shares were traded and roughly $14 billion in stock value vanished. Bankers’ attempts to restore confidence failed.
The Dow eventually fell nearly 90% from its pre-crash value, reaching its low in July 1932. Thousands of banks and businesses failed, while unemployment and economic uncertainty spread. Congress responded with banking separation, securities regulation, disclosure requirements, and measures against market manipulation. Historians still debate whether the crash caused the Great Depression or intensified a broader economic collapse.
