On what date did the 2015 Chinese stock market bubble begin to pop?

The 2015 Chinese stock market bubble began to pop on June 12, 2015. That date marked the start of the prolonged 2015–2016 Chinese stock market turbulence, after a dramatic rise in mainland share prices.

The Shanghai market had surged as easy credit, margin borrowing, and heavy participation by individual investors pushed valuations sharply higher. When the bubble began to deflate, selling accelerated and the Shanghai Stock Exchange lost roughly one-third of its A-share value within a month. By early July, more than 1,400 companies had suspended trading in an attempt to limit losses.

The later dates in the choices were important but describe different stages. August 24, 2015, became the most famous “Black Monday” after the Shanghai index fell 8.48%. July 8 fell during the first major sell-off, while January 4, 2016, belonged to a later wave of turbulence involving China’s new circuit-breaker system.

The episode was not a single-day crash. It stretched from June 2015 into early February 2016, with government interventions, trading halts, currency concerns, and global fears about China’s economic slowdown shaping the aftermath.
