Which 2015 collapse saw China’s Shanghai Composite fall sharply after its June peak?

The 2015 collapse in which China’s Shanghai Composite fell sharply after its June peak was the 2015 Chinese stock market crash.

Chinese mainland shares had risen rapidly during the first half of 2015, supported by retail speculation, margin borrowing, and expectations of continuing economic growth. The Shanghai Composite reached a local peak on June 12, 2015. It then fell by more than 30 percent over the following weeks, producing intense volatility and forced selling.

Chinese authorities responded with measures including trading suspensions, restrictions on some share sales, support for major stocks, and investigations into market activity. The turbulence continued into 2016, when another sharp decline prompted global concern about China’s economy and financial markets.

The event was not the same as the 1997 Asian financial crisis. That earlier crisis began with Thailand’s baht devaluation and spread through several Asian economies, whereas the 2015 episode centered on China’s domestic stock market and its policy response.
