Which stock exchange crash in October 1929 is associated with the start of the Great Depression?

The Wall Street Crash was the October 1929 stock-exchange collapse associated with the start of the Great Depression.

The market had risen sharply during the 1920s, and many investors bought shares with borrowed money through margin accounts. When prices began falling, forced selling amplified the decline. The most famous sessions were Black Thursday on October 24, Black Monday on October 28, and Black Tuesday on October 29.

The crash severely damaged confidence and wealth, but it was not the only cause of the Great Depression. Bank failures, reduced consumer spending, declining industrial output, agricultural distress, and international debt problems prolonged and deepened the downturn.

The phrase “Wall Street Crash” usually refers to the 1929 U.S. market collapse, while “Great Depression” describes the much broader economic crisis that followed. The market’s recovery took years, and the Dow did not regain its September 1929 peak until 1954.
