On what date did China’s Shanghai Composite plunge 8.49% during the 2015 stock-market crash?

China’s Shanghai Composite plunged 8.49% on August 24, 2015, during the 2015 stock-market crash.

The session became known internationally as “Black Monday” because the Shanghai Composite suffered one of its sharpest daily falls in years. The decline followed weeks of severe volatility in mainland Chinese equities and renewed concern about slowing economic growth, corporate profits, and the effectiveness of government market interventions.

Chinese authorities had attempted to support share prices through measures including state-backed buying, restrictions on some sales, and changes to financing rules. Those measures failed to restore lasting confidence. The August 24 sell-off also affected markets around the world, including major European and U.S. indexes.

The date is sometimes confused with June 12, 2015, when the Chinese market reached a short-term peak before the broader decline began. It is also distinct from the 1987 Black Monday, which occurred on October 19 and involved a global equity-market collapse led by the United States.
