South Korea Imposes Tighter Rules on Leveraged ETFs as Retail Trading Surge Cools Volatility Concerns​

South Korean authorities are stepping up regulatory scrutiny over leveraged investment products after retail trading activity in single-stock leveraged exchange-traded funds (ETFs) showed signs of cooling, following a period of excessive speculative demand. Finance Minister Koo Yun-cheol confirmed that the government is committed to market stability and will quickly implement stricter restrictions designed to rein in high-risk trading behaviors.

The enhanced regulations follow an earlier series of rules regulators deemed insufficient to manage the surge in retail participation within these volatile products. The financial market structure, which includes single-stock leveraged ETFs tracking major companies, remains a key focus for regulatory intervention.

New Limits Aims to Curb Excessive Exposure​

One of the most significant new measures introduced is a proposed cap on investments made into single-stock leveraged ETFs. Under the tightened regulations, investors will be limited to investing 20% of an individual's total investment assets in these specific products.

The restriction is aimed squarely at limiting excessive exposure to highly volatile products that track a single stock while using leverage. These rules represent a clear move by regulators seeking to mitigate amplified market volatility resulting from speculative retail trading activity.

Trading Volumes Plummeting Across Key ETFs​

The regulatory push appears to be having an impact on the sector's activity levels. Data cited by Reuters shows a substantial decline in trading volume for major single-stock leveraged ETFs over the last few days.

For instance, daily trading volume in the TIGER SK Hynix single-stock leveraged ETF dropped dramatically to 291 billion won ($203.5 million) on Monday. This marked a sharp reduction from the 482 billion won recorded on Friday, after the fund had seen exceptionally high volumes prior.

Similarly, trading in the TIGER Samsung Electronics single-stock leveraged ETF also saw a steep decline. Daily turnover fell to 234 billion won on Monday from 511 billion won on Friday, following a peak of 1.4 trillion won recorded on Thursday, according to exchange data.

Market Share of Leveraged ETFs Falls Significantly​

The regulatory actions are being viewed by analysts as potentially alleviating pressure on the broader equity market. Han Ji-young, an analyst at Kiwoom Securities, noted that the decline in leveraged ETF trading seems to have contributed positively to lower day-to-day volatility within the benchmark KOSPI index.

More tellingly, there has been a sharp drop in the share of these complex products within the total KOSPI market turnover. Trading volumes in these single-stock leveraged ETFs accounted for 33.4% of total KOSPI turnover on July 30. This figure fell significantly to 6.6% on July 31 and further down to 5.4% on August 1.

Past Highs Highlight Speculative Demand​

The two monitored ETFs are among roughly a dozen single-stock leveraged listings available in South Korea, and both had experienced periods of exceptionally strong retail demand earlier this summer. Prior to the regulatory intervention, these funds recorded record highs in trading volumes during late June. The TIGER SK Hynix ETF reached a turnover of 3.9 trillion won, while the TIGER Samsung Electronics ETF recorded a high of 3.6 trillion won.
