On which date did China’s 2015 Black Monday cause the Shanghai Composite to fall 8.49%?

China’s 2015 Black Monday, when the Shanghai Composite fell 8.49%, occurred on August 24, 2015.

The sharp decline followed a broader sell-off that had begun after the Shanghai Composite reached a 2015 peak in June. Concerns included slowing Chinese economic growth, falling commodity prices, weakening global demand, and uncertainty about government intervention in the stock market.

The August 24 drop spread rapidly through international markets. European and U.S. shares also fell, and the Dow Jones Industrial Average experienced a historically large intraday swing. The episode showed how closely connected major financial markets had become.

The phrase Black Monday is not unique to China’s 2015 crash. It is also used for October 19, 1987, the date of the largest one-day percentage fall in the Dow. The two events occurred in different countries and decades.
