South Korean stock market faces extreme volatility amid chip selloff

KOSPI semiconductor selloff leveraged ETFs Samsung Electronics SK Hynix

South Korea's KOSPI index has experienced extreme volatility, characterized by sharp plunges and rapid recoveries. In one notable session, the index fell nearly 6%, triggering a circuit breaker as a global semiconductor selloff hit major domestic firms. Samsung Electronics and SK Hynix saw significant declines, with shares dropping approximately 7% and 8.6% respectively.

Financial authorities have held emergency meetings to address the impact of single-stock leveraged ETFs. Analysts suggest these high-leverage products, which amplify daily returns, have exacerbated market volatility by forcing massive rebalancing trades during price swings. This has created a cycle where price drops trigger forced liquidations, further driving down values.

Investor behavior remains deeply divided. While individual retail investors have heavily utilized inverse ETFs to bet against the market, foreign and institutional investors have frequently taken opposing positions, buying semiconductor-related leverage products. Market stability continues to be pressured by rising U.S. bond yields, increasing oil prices, and geopolitical tensions in the Middle East.
