Which 2015 Chinese stock-market crash followed a sharp rise in mainland share prices earlier that year?

The Chinese market collapse after the 2015 mainland share-price surge was the 2015–2016 Chinese stock-market turbulence.

Shanghai and Shenzhen share prices rose dramatically from mid-2014 into June 2015, supported by retail participation, margin borrowing, and expectations of continued economic growth. The Shanghai Stock Exchange Composite Index then fell sharply from its June 2015 peak. Volatility continued into early 2016.

Chinese authorities responded with measures including trading suspensions, restrictions on some selling, state-linked purchases, and changes to margin rules. A major market fall on January 4, 2016, also triggered newly introduced circuit breakers, which were suspended after causing further disruption.

The episode is sometimes called the Chinese stock-market crash of 2015, but the cited article uses the broader term “2015–2016 Chinese stock-market turbulence.” The event concerned mainland Chinese exchanges, not Hong Kong’s separate market.
