Which U.S. market day in 1929 is known as Black Tuesday during the Wall Street Crash?

Black Tuesday during the 1929 Wall Street Crash was October 29, 1929.

On that day, roughly 16 million shares changed hands on the New York Stock Exchange, setting a trading-volume record that stood for decades. The Dow Jones Industrial Average fell about 12%, adding to the losses recorded during the previous week.

Black Tuesday followed Black Thursday on October 24 and Black Monday on October 28. These labels describe especially dramatic trading days during the market’s collapse, although the crash was a longer process rather than a single event. The market had already climbed for years, supported partly by widespread margin borrowing.

The crash caused enormous financial losses and damaged confidence, but historians generally do not treat it as the sole cause of the Great Depression. Bank failures, falling production, reduced demand, international debt problems, and policy decisions also shaped the economic crisis. The Dow continued declining after October 29 and did not reach its lowest point until July 1932.
