South Korean Single-Stock Leveraged ETFs Fuel Market Volatility and Delisting Fears

South Korea introduced single-stock leveraged ETFs tied to Samsung Electronics and SK Hynix on May 27, 2026, seeking to broaden investor choice and draw trading back from overseas markets. Retail demand quickly made the products systemically important: turnover across 16 related funds reached 18.3 trillion won on July 14, about 40% of KOSPI trading. Their daily rebalancing can amplify moves in the country’s two dominant chipmakers, raising concerns over investor protection and broader market stability.

The Financial Services Commission, Financial Supervisory Service and Korea Exchange raised the minimum deposit to 30 million won from 10 million won, with cash required, effective July 31. Trading value in leveraged products linked to Samsung Electronics and SK Hynix subsequently plunged nearly 90%. Investors shifted toward sector ETFs and alternatives listed in markets including Hong Kong. Brokerages warned that such offshore flows could eventually return in concentrated bursts, adding another source of volatility to Korean equities.

South Korea introduced its first 16 single-stock leveraged ETFs tied to Samsung Electronics and SK hynix on May 27, giving retail investors access to products designed to deliver twice the shares’ daily moves. Demand quickly became concentrated in the two chipmakers, which accounted for 52% of KOSPI capitalization by July 15. Because the funds reset exposure each day, their rebalancing can intensify buying during rallies and forced selling during declines, magnifying swings in an already concentrated benchmark.

The KOSPI triggered 20-minute marketwide circuit breakers on July 28 and July 29 after falling more than 8% on both days. On July 28, the index was at 6,212.26 when the halt was activated and later closed 10.84% lower. Finance Minister Koo Yun-cheol apologized for the rushed rollout. The Financial Services Commission raised the minimum cash deposit for trading single-stock leveraged products to 30 million won ($20,000) from 10 million won, bringing the tougher requirement forward to July 31.

South Korea had not previously approved leveraged ETFs tracking individual stocks. Its first authorization of 2x products tied to Samsung Electronics and SK Hynix reflects a policy push to give investors exposure to growth in AI and semiconductors while reducing capital outflows to overseas markets. Both companies are major players in the global memory-chip industry. The products will amplify daily price moves, increasing the risk of losses as well as gains.

The first 2x leveraged single-stock ETFs are scheduled to list in South Korea on May 27. Fundraising targets and listing sizes have not been disclosed. South Korea’s Financial Supervisory Service (FSS) warned that a concentration of inflows into products linked to Samsung Electronics and SK Hynix could intensify volatility in their share prices and the broader market. The regulator has planned safeguards including margin requirements and investor education programs.
