On what date did China’s Shanghai Composite suffer its 2015 Black Monday plunge?

China’s Shanghai Composite suffered its 2015 Black Monday plunge on August 24, 2015.

The index fell 8.49% that day, its largest one-day percentage decline since February 2007. The fall came after weeks of turbulence in Chinese equities, following a sharp rise in share prices earlier in the year and concerns about economic growth, corporate earnings, and the government’s market-support measures.

The sell-off spread through international markets. U.S. and European shares also dropped, and commodity prices weakened as investors worried about China’s economy and global demand. The episode showed how closely major markets had become linked through trade, investment, and expectations about growth.

The term Black Monday is not unique to 2015. It is also used for October 19, 1987, and other severe market declines, so the year and exchange are essential when identifying China’s event.
