What was the name of China's major stock-market crash that began after its June 2015 peak?

China’s major stock-market crash that began after its June 2015 peak was the 2015 Chinese stock market crash. The Shanghai Composite had risen sharply during the preceding year, fueled partly by retail participation and margin financing.

After reaching a high on June 12, 2015, Chinese share prices fell rapidly. The Shanghai Composite lost more than 30 percent over roughly one month, and further turbulence continued into 2016. Authorities responded with measures including trading halts, restrictions on some share sales, and support for the market.

The crash affected mainland Chinese equities rather than representing a complete collapse of China’s economy. The Shanghai and Shenzhen exchanges also differ from Hong Kong’s stock exchange, so the event should not be treated as a single identical fall across every Chinese market. It is commonly grouped with the 2015–16 Chinese stock-market turbulence.
