Which Chinese stock exchange’s benchmark led the 2015 Chinese stock-market crash?

The Shanghai Stock Exchange’s benchmark led the 2015 Chinese stock-market crash.

The Shanghai Composite Index rose rapidly during the first half of 2015, supported by increased retail participation, margin borrowing, and optimism about Chinese economic reforms. After reaching a 2015 peak on June 12, the market reversed sharply. The Shanghai Composite then lost a large portion of its value during the summer sell-off.

Authorities responded with measures including trading suspensions, restrictions on some selling, investigations into market activity, and efforts to support share prices. The turbulence spread beyond mainland China as investors reassessed Chinese growth and the potential effects on global companies and commodities.

The Shenzhen Stock Exchange was also deeply affected, and Hong Kong’s market suffered related volatility. However, the Shanghai Composite and the Shanghai Stock Exchange are the central reference points for the crash’s mainland benchmark.
