Market Impact

The crash in South Korean equities, led by AI chip stocks, signals a sharp reversal of a crowded trade and may spill over to global tech markets. The forced deleveraging of retail investors could lead to further downside, while government intervention may provide some support.

Event Summary

South Korean stocks plunged for a second straight session on July 29, 2026, with the KOSPI index diving as much as 12.6% before closing down 6%, extending a near-11% rout from the previous day. The two-day selloff wiped as much as $2.18 trillion from Seoul's equity market, driven by a forced unwind of leveraged positions held by retail investors in AI-related chip stocks. SK Hynix reported a six-fold earnings jump but shares fell 9.6% as results lagged lofty expectations; Samsung Electronics dropped 5.2%. Finance Minister Koo Yun-cheol apologized for the introduction of single-stock leveraged ETFs and said the government is reviewing market stabilization measures. The South Korea — Bank of Korea governor and financial regulators met to discuss the situation. The KOSPI has fallen over 40% from its peak a month ago but remains up 41.5% year-to-date in USD terms.
