Which Chinese benchmark index fell 8.48% on August 24, 2015?

The Shanghai Composite Index fell 8.48% on August 24, 2015. The drop occurred during China’s 2015–2016 stock market turbulence and became widely known as China’s “Black Monday.”

The Shanghai Composite tracks shares listed on the Shanghai Stock Exchange and is one of the most watched indicators of mainland China’s equity market. After a powerful rally, concerns about slowing growth, falling commodity prices, the yuan, and the sustainability of high valuations triggered heavy selling. The index’s August 24 loss was its largest single-day fall since 2007.

The figure is sometimes reported as 8.49%, depending on rounding or the data source. That small discrepancy does not change the answer: the relevant benchmark was the Shanghai Composite, not Hong Kong’s Hang Seng Index, Japan’s Nikkei 225, or South Korea’s KOSPI.

The sell-off also reverberated globally. On August 25, the Shanghai index fell more than 7% again, while international markets experienced major losses. The episode demonstrated how closely investors had begun linking Chinese financial conditions with the wider global economy.
