What name is commonly given to China's dramatic stock-market collapse that began after the Shanghai Composite peaked in June 2015?

China's dramatic stock-market collapse beginning after the Shanghai Composite's June 2015 peak is commonly called the Chinese stock market crash.

The Shanghai Composite rose rapidly during the year leading to June 2015, helped by increased participation from individual investors and widespread margin borrowing. The index reached a high on June 12, 2015, but then reversed sharply as regulators tightened rules and leveraged investors faced losses.

By August 2015, the decline had become a global market event. China's authorities introduced measures including trading restrictions, limits on share sales by major shareholders, and support for stock purchases. The turbulence continued into early 2016, when further falls in Chinese shares contributed to international market anxiety.

This episode is sometimes confused with China's 2007–08 stock-market decline or with the broader Asian financial crisis of 1997. The 2015 event was centered on mainland Chinese equities and was driven largely by a reversal of a leveraged domestic stock boom.
