Which 2015 Chinese market crash followed a sharp fall in the Shanghai Composite Index?

The Chinese market collapse that began in 2015 was the 2015–2016 Chinese stock-market crash.

The Shanghai Composite Index rose dramatically between mid-2014 and June 2015, fueled partly by margin borrowing and strong retail speculation. After the market peaked, share prices fell rapidly, and leveraged investors faced forced selling as the value of collateral declined.

Chinese authorities responded with measures including trading suspensions, restrictions on some share sales, and support for major stocks. The Shanghai Composite continued to experience major volatility into early 2016, when another sharp global sell-off added pressure.

The crash was concentrated in mainland Chinese equities and should not be confused with the 2015 currency devaluation alone. It also differed from the 2007–2008 global financial crisis in its immediate causes and policy response.
