What was the name given to the New York Stock Exchange crash on October 29, 1929?

The New York Stock Exchange crash on October 29, 1929, was called Black Tuesday.

Black Tuesday followed several days of heavy selling, including Black Thursday on October 24 and another severe decline on October 28. On October 29, about 16 million shares changed hands, a record at the time, as investors rushed to sell.

The crash did not by itself cause the entire Great Depression, but it severely damaged confidence and exposed weaknesses in the American economy. Falling share prices reduced household wealth, weakened businesses, and contributed to bank failures and declining investment.

A common mix-up is treating Black Tuesday as the sole beginning of the Depression. Economic contraction had already begun in 1929, and the downturn became global through trade, banking, and financial links. The crash remains one of the best-known events in financial history.
