Which 2015 Chinese market crash followed the bursting of a major mainland stock-market bubble?

The 2015 Chinese market crash was a sharp collapse in mainland Chinese share prices after a major stock-market bubble.

The Shanghai Composite Index more than doubled between June 2014 and June 2015, supported by retail participation, margin borrowing, and expectations of continued economic growth. The index then fell rapidly beginning in June 2015. Forced selling from leveraged investors intensified the decline, while official interventions attempted to stabilize prices.

Chinese authorities suspended some initial public offerings, restricted certain sales, and encouraged state-linked funds to buy shares. The turbulence continued into early 2016, when another dramatic sell-off led to temporary trading halts under the country’s new circuit-breaker system.

The episode is often discussed alongside China’s broader economic slowdown and concerns about debt. It was not the same event as the 2008 global financial crisis, although international investors worried that Chinese weakness could affect markets and commodity demand worldwide.
