What was the name of the 2015 market collapse that began after Chinese shares peaked in June?

The 2015 Chinese stock market crash was the sharp decline that followed the peak of Chinese share prices in June 2015.

The Shanghai Composite had more than doubled in the year leading up to its June 12 peak, helped by retail investor enthusiasm, margin borrowing, and expectations of continued economic support. Once prices began falling, leveraged investors faced margin calls, which forced additional selling. Authorities introduced emergency measures, including trading restrictions and support efforts.

The turbulence spread beyond mainland China as investors worried about China’s growth, commodity demand, and global trade. The market experienced repeated large moves rather than one universally agreed single crash day, which is why descriptions sometimes use “turbulence” instead of “crash.”

This episode is distinct from the Asian financial crisis of 1997, which began with currency and debt stress in Southeast Asia. It also differs from China’s later property-sector problems, which centered more directly on real estate developers and debt.
