What was the 2015 collapse in Chinese share prices, which followed a rapid rise and margin lending boom, called?

The 2015 collapse in Chinese share prices following a rapid rise and margin-lending boom was called the Chinese stock market crash.

China’s mainland equity markets surged during the first half of 2015, with the Shanghai Composite more than doubling from its mid-2014 level. Many investors used borrowed money to buy shares, increasing both gains and vulnerability.

The Shanghai Composite peaked at 5,178.19 on 12 June 2015. It then fell sharply, prompting government interventions that included trading restrictions, limits on new listings, and efforts to support major shares.

The turmoil continued into 2016, but it did not represent a complete collapse of China’s economy. It is also separate from the 2015–2016 global commodity-price downturn, which had different main causes and affected energy-producing countries especially strongly.
