What was the name of the 1987 crash day when the Dow fell 22.6 percent?

Black Monday was the 1987 crash day when the Dow Jones Industrial Average fell 22.6 percent.

The date was October 19, 1987. Stock markets around the world fell sharply, making the episode a global crash rather than an event limited to the United States. The Dow lost 508 points, which was about 22.6 percent of its value at the previous close.

The causes remain debated. Analysts have pointed to high valuations, rising interest rates, concerns about trade and economic policy, and program trading. Portfolio-insurance strategies were designed to limit losses, but their selling could reinforce a downward move when many investors used similar rules.

Black Monday is easy to confuse with other market dates. Black Monday in 1929 refers to October 28, while Black Tuesday in 1929 refers to October 29. The 1987 crash led exchanges and regulators to develop coordinated circuit breakers, which can temporarily halt trading after exceptionally large index declines. Despite the severity of the day, the broader economy did not enter a depression comparable to the 1930s.
