Which 2015 Chinese stock-market crash began after the Shanghai Composite peaked in June?

The Chinese stock market crash began after the Shanghai Composite peaked in June 2015.

The Shanghai Composite reached 5,178.19 on June 12, 2015, after a rapid rise fueled by retail participation, margin borrowing, and strong expectations about Chinese equities. Prices then fell sharply, with repeated volatile sessions and emergency efforts by Chinese authorities to support the market and restrict selling.

The turbulence continued into 2016, when global markets were again shaken by concerns about China’s growth and currency policy. The episode is often confused with the 2015 Chinese currency devaluation, but the stock-market decline and the renminbi’s exchange-rate changes were related yet separate developments. The Shanghai Composite is a mainland Chinese index; it should not be treated as the same market as Hong Kong’s Hang Seng Index.
