Which exchange’s Shanghai Composite Index fell sharply during China’s 2015 stock-market crash?

The Shanghai Stock Exchange was the exchange whose Shanghai Composite Index fell sharply during China’s 2015 stock-market crash.

Chinese share prices rose rapidly from mid-2014 into June 2015, supported by abundant margin financing and strong participation from individual investors. The Shanghai Composite reached a 2015 intraday peak above 5,100 points on June 12. After that peak, falling confidence and forced deleveraging produced a steep decline.

The index lost more than 30 percent in the following weeks, despite government efforts to support the market. These efforts included restrictions on some share sales, investigations of short selling, suspension of initial public offerings and support from state-linked funds. Trading disruptions and policy uncertainty added to investor concern.

The crash is often described as a Chinese stock-market crash, but it was not identical to the country’s broader economic slowdown. The Shanghai Composite is a benchmark of shares listed in Shanghai, while Shenzhen and Hong Kong have separate markets and indexes. That distinction makes Shanghai Stock Exchange the specific answer to the question.
