Which 2015 event saw China’s Shanghai Composite fall about 8.5% in one day?

The 2015 Chinese stock-market crash included Black Monday, when the Shanghai Composite fell about 8.5% in one day.

On August 24, 2015, the Shanghai Composite Index dropped 8.49%, its largest single-day percentage fall since 2007. The date became known internationally as Black Monday. Chinese shares had already declined substantially after a rapid rise that had begun in 2014 and peaked in June 2015.

Investors worried about slowing Chinese economic growth, weakening industrial activity, falling commodity prices, and the effects of earlier market interventions. The sell-off spread to markets around the world, including Europe and the United States. The Dow Jones Industrial Average fell more than 1,000 points shortly after the U.S. market opened, although it recovered much of the loss before closing.

This episode is distinct from Black Monday in 1987, which involved a global crash led by a 22.6% one-day fall in the Dow. It is also separate from China’s 2016 trading interruptions, which followed further market declines.
