Which Chinese stock index fell 8.5% on August 24, 2015, during the global stock-market sell-off?

The Shanghai Composite Index fell 8.5 percent on August 24, 2015, during a global stock-market sell-off. The drop was widely reported as part of a sharp Chinese market decline that spread anxiety to exchanges around the world.

China's stock market had risen rapidly during the preceding year, supported by investor enthusiasm, margin borrowing, and expectations of continued economic growth. By the summer of 2015, prices were falling, and efforts by Chinese authorities to stabilize the market had not restored confidence. The August 24 session became known internationally as Black Monday because major indexes in Europe and the United States also declined.

The Shanghai Composite tracks the performance of shares listed on the Shanghai Stock Exchange, including both A shares and B shares. It is not the same as Hong Kong's Hang Seng Index or the Shenzhen Component Index. The 2015 episode was a market crash and volatility shock, but it was distinct from the 2008 global financial crisis and the 2020 pandemic sell-off.
