Which global stock-market crash followed the U.S. stock market’s sharp fall on October 24, 1929?

The global stock-market crash that followed the U.S. market’s sharp fall on October 24, 1929, was the Wall Street Crash of 1929.

October 24 became known as Black Thursday after heavy selling overwhelmed the New York Stock Exchange. Although financiers and bankers attempted to reassure investors, volatility returned, leading to Black Monday and Black Tuesday later that month. The episode became the best-known market collapse of the interwar period.

The crash spread beyond the United States through international financial links, falling trade, and reduced investment. It helped deepen an economic crisis that became the Great Depression, but historians do not treat the crash as the sole cause. Monetary policy, debt, banking failures, protectionism, and declining production also mattered.

The Panic of 1907 and Black Monday of 1987 were separate events. The dot-com crash occurred decades later, after the technology-stock bubble peaked in 2000.
