Which 2015 crash saw China’s Shanghai Composite lose more than 40% from its June peak?

The 2015 crash in which China’s Shanghai Composite lost more than 40% from its June peak was the Chinese stock market crash.

Chinese shares rose rapidly during the first half of 2015, fueled partly by retail participation, margin borrowing, and strong expectations about economic growth. The Shanghai Composite peaked on June 12 before falling sharply over the following weeks.

Authorities responded with trading restrictions, investigations, support purchases, and measures intended to limit forced selling. The market experienced several violent sessions in August, including the global “Black Monday” of August 24, 2015, when worldwide equities dropped.

The episode was not the same as the 1997 Asian financial crisis, which began with pressure on Thailand’s currency. The 2015 Chinese turbulence centered on mainland equity markets and concerns about leverage, valuation, and China’s economic slowdown.
