Which 2015 event describes China's sharp stock-market decline after the Shanghai Composite peaked in June?

China’s sharp 2015 decline after the Shanghai Composite peaked in June is known as the Chinese stock market crash.

The Shanghai Composite reached 5,178.19 points on June 12, 2015, after a powerful rally that attracted many retail investors and was supported by margin borrowing. Prices then fell rapidly as leveraged positions were unwound and confidence weakened. The Shenzhen market and other Chinese shares also experienced severe volatility.

Chinese authorities responded with measures including trading suspensions, restrictions on share sales by major shareholders, investigations of short selling, and support for state-linked buying. These interventions slowed some selling but also raised questions about the government’s role in the market.

The event is sometimes described as a single crash, although the turbulence continued into 2016. It was not the same as China’s later property-sector problems, which involved real-estate developers, housing demand, and debt rather than primarily listed equities.
