Black Monday

19 October 1987

Black Monday refers to the stock market crash of 19 October 1987, when the Dow Jones Industrial Average fell by more than twenty percent in a single day, the largest one-day percentage fall in its history. The panic began in Asian markets and spread to Europe and the United States, with markets in Hong Kong, London and elsewhere also dropping sharply. Possible causes include overvalued shares, computerized program trading and portfolio insurance strategies, which forced automatic selling as prices fell. The Federal Reserve, under Alan Greenspan, promised to provide liquidity, and markets recovered fairly quickly without a recession. Stock exchanges later introduced circuit breakers to pause trading in sharp declines.
