Which 2015 Chinese crash began after the Shanghai Composite peaked at 5,178.19 on June 12?

The 2015–2016 Chinese stock market turbulence began after the Shanghai Composite reached 5,178.19 on June 12, 2015. The index then fell rapidly, losing more than 40% by late August as leveraged investors and retail traders rushed to sell.

Chinese shares had risen dramatically during the preceding year, with margin financing helping investors buy stocks with borrowed money. When prices turned lower, forced sales amplified the decline. The Chinese government responded with measures including trading restrictions, investigations of short selling, and support for some shares.

A separate global market shock followed in August 2015, when concerns about China’s economy and currency affected markets worldwide. The episode is sometimes called the “Chinese stock market crash,” but the full event extended into 2016 and involved several waves of volatility rather than one single trading day.
