What was the name of the 2015 collapse in Chinese share prices that followed a dramatic rise in the Shanghai market?

The 2015 collapse in Chinese share prices that followed a dramatic rise in the Shanghai market was the 2015 Chinese stock market crash.

The Shanghai Composite Index rose steeply during the year, helped by retail investor participation, margin financing, and expectations of continuing economic growth. After reaching a peak on 12 June 2015, the index began a rapid decline. By August, the sell-off had spread into international markets.

Chinese authorities responded with measures including trading restrictions, investigations, changes to initial public offerings, and support for major shares. On 24 August 2015, a day widely called Black Monday, the Shanghai Composite fell 8.49 percent, while markets in Europe and the United States also recorded substantial losses.

The episode is sometimes confused with China’s market turbulence in early 2016, when circuit breakers contributed to further disruption. The 2015 crash was not the same event as the 2007–08 global financial crisis, although it intensified concerns about China’s economy and global growth.
