Korean financial regulators and industry experts are debating stricter controls on single-stock leveraged ETFs for Samsung Electronics and SK Hynix following excessive speculation since their May 27 listing. From June 1 to June 10, individual investors net purchased ₩1.66 trillion worth of SK Hynix leveraged ETFs while institutions sold ₩1.57 trillion, according to Korea Exchange data. The Korea Financial Investment Association is collecting proposals from securities firms to curb volatility, with three main solutions under consideration: raising the minimum deposit requirement from the current ₩10 million, imposing position limits per investor, and strengthening mandatory investor education. Experts attribute abnormal market volatility to the 'short gamma' effect generated by concentrated demand in these products, which mechanically amplifies price swings in the underlying stocks. South Korea previously implemented similar cooling measures in 2011 when it raised option multipliers from ₩100,000 to ₩500,000 and introduced a ₩15 million minimum deposit for stock warrant securities.
Samsung and SK Hynix Leveraged ETFs Dominate Trading Volumes
According to Korea Exchange data from June 1 to June 10, five of the top 10 ETF trading volumes were single-stock leveraged products tied to Samsung Electronics and SK Hynix. The third and fourth highest-traded ETFs during this period were 'SOL SK Hynix Futures Single Stock Leverage' (5 billion shares) and 'KODEX SK Hynix Single Stock Leverage' (4.2 billion shares). The sixth, seventh, and tenth positions were occupied by Samsung Electronics and SK Hynix leveraged products.
From June 1 to June 10, individual investors net purchased ₩1.66 trillion worth of seven SK Hynix single-stock leveraged ETFs, while institutions and foreign investors net sold ₩1.57 trillion and ₩136.1 billion respectively. During the same period, individuals bought ₩599.1 billion worth of seven Samsung Electronics single-stock leveraged ETFs, while institutions sold ₩516.6 billion.
Three Regulatory Measures Proposed by Financial Industry
The Korea Financial Investment Association is collecting proposals from securities firms to protect investors in single-stock leveraged ETFs. The three main solutions under discussion are raising minimum deposit requirements, imposing position limits per investor, and strengthening investor education.
The first measure involves raising the basic deposit requirement. Currently, investors need a minimum of ₩10 million to trade single-stock leveraged ETFs. South Korea implemented similar measures in 2011 when derivatives markets showed signs of overheating. Financial authorities raised the option multiplier from ₩100,000 to ₩500,000 and introduced a ₩15 million minimum deposit for stock warrant securities (ELW) to cool the market.
The second proposal is a 'customized investment limit per investor.' This measure would prohibit new purchases when ultra-high-risk assets like single-stock leveraged products exceed a certain proportion of an investor's total financial portfolio.
The third solution is 'strengthening investor education.' Current regulations require only one-time education before an investor's initial purchase of single-stock leveraged ETFs. The proposed reform would mandate periodic re-education and advanced training on market risks.
Experts Cite Short Gamma Effect as Volatility Driver
Yu Myeong-gan, researcher at Mirae Asset Securities, stated: "The abnormal volatility expansion observed in the domestic stock market recently originated from the short gamma structure of single-stock leverage rather than changes in corporate fundamentals."
Lee Hyo-seop, director of the Capital Market Research Institute's financial industry division, stated: "Individuals are entering single-stock leveraged ETF products excessively and bearing hedging costs and management fees caused by volatile markets. The system must be urgently reformed so that only individual investors with proven substantial risk tolerance can enter the market, and regulatory arbitrage between products must be resolved."
