In late September 2026, the South Korean ETF market experienced a significant shift in trading activity driven by regulatory changes. Initially, data from the Korea Exchange showed a divergence in strategies: foreign investors favored leverage products like ‘KODEX Leverage’ to bet on market gains, while individual investors utilized inverse products to hedge against volatility. Following the implementation of stricter financial regulations, trading volume for single-stock leverage and inverse ETFs plummeted by approximately 92%. This decline followed an increase in basic deposit requirements, which rose from 10 million won to 30 million won in cash. Consequently, the average daily trading value for 16 specific ETF types fell from 12.25 trillion won to 990 billion won. As a result of these requirements, individual investors transitioned from net buying to net selling. While the drop in volume indicates a cooling of high-risk trading, analysts have raised concerns regarding a ‘balloon effect,’ where demand may migrate to unregulated or less restricted financial products. By early October, regulatory efforts to curb market overheating expanded. The Financial Services Commission is preparing to increase the minimum trading unit for single-stock leverage ETFs from one share to 20 shares. To assist investors holding between one and 19 shares, authorities are considering allowing these ‘odd lots’ to be sold via after-hours closing price trading for a set period. Market data suggests volatility is subsiding; the combined market capitalization of the 16 ETF products in question has fallen from a June peak of 16.5 trillion won to between 6 and 7 trillion won. During a National Assembly audit, lawmakers criticized these products, with some alleging they caused approximately 54 trillion won in losses to individual investors. Concerns regarding the ‘balloon effect’ have intensified as authorities monitor the rise of offshore perpetual futures trading on global cryptocurrency platforms.
