Which 2015 market crash began when China's Shanghai Composite fell sharply after its June peak?

The 2015 market crash that began when China’s Shanghai Composite fell sharply after its June peak was the Chinese stock-market crash.

China’s mainland stock market had risen rapidly in the first half of 2015, helped by retail-investor participation, margin financing, and expectations of continued economic growth. The Shanghai Composite reached a 2015 intraday high of 5,178.19 on 12 June.

Prices then reversed. By 8 July, the index had lost more than 30% from its peak, prompting authorities to restrict some short selling, support share purchases, and suspend or limit trading in many companies. International markets were also unsettled by concerns about China’s economy and currency policy.

The episode is sometimes confused with the 1997 Asian financial crisis, but the 2015 event centered on China’s equity-market bubble and its reversal. It also included renewed turbulence in 2016, so references to Chinese stock-market turmoil can cover more than one sell-off.
