South Korean investors are rapidly redirecting their capital toward US-listed leveraged exchange-traded funds (ETFs) following the government's stricter regulations on single-stock leveraged ETFs. According to data from the Korea Exchange (KRX) information system on the 5th, trading volumes have plummeted after financial authorities raised the basic margin requirements and investment limits for these products.
Trading amounts for the 16 single-stock leveraged and inverse ETFs listed in South Korea fell 89.8% from 13.0361 trillion won on the 15th of last month, before the regulations took effect, to 1.3329 trillion won the previous day. Market observers attribute this decline primarily to the higher entry barriers for individual investors. Previously, the basic margin requirement was raised from 10 million won, which could include available securities, to 30 million won in cash.
Conversely, interest in offshore leveraged ETFs has intensified. During the same period, the top-ranked overseas stock by net purchase value among South Korean investors was the US-based Direxion Daily Semiconductor Bull 3X Shares (SOXL), with a net settlement amount of $2.48789 billion. Meanwhile, the GraniteShares 2x Long TSLA Daily ETF (TSLL), a two-times leveraged Tesla fund, saw net purchases of $214.36 million, ranking sixth. The Direxion Daily South Korea Bull 3X Shares (KORU), a three-times leveraged Korea ETF, also attracted $130.95 million in net inflows, placing eleventh.
Market analysis suggests that South Korean investors have not abandoned risky asset investments but have instead shifted their allocations overseas, a phenomenon described as a "balloon effect." While domestic investors must meet margin requirements and face investment limits for local products, US-listed high-risk leveraged ETFs remain accessible without significant constraints, leading some to argue that the regulation itself is driving capital outflow. Notably, US leveraged ETFs expose investors to exchange rate risks, and some products employ leverage structures exceeding two times, up to three times, making them potentially more volatile than their domestic counterparts. Concerns are growing that restricting local products may inadvertently expose investors to even higher risks.
Professor Son Jae-sung from the Department of Accounting at Soongsil University commented, "While this regulation is intended to protect investors, it comes after losses have already occurred, making it largely a remedial measure. South Korean single-stock leveraged ETFs are overly volatile, whereas the US market is relatively stable, so the shift to overseas leveraged ETFs is a natural outcome." He added, "As long as the current structure restricts only domestic products while leaving overseas ones untouched, the trend of concentrated overseas investment is likely to persist."
The financial authorities' tightening of single-stock leveraged ETF regulations stems from the structural risks inherent in these products. Leveraged ETFs track two times the daily return of an underlying asset, which can lead to "negative compounding" during periods of high market volatility, amplifying losses. However, given the observed decline in domestic trading and the shift toward overseas leveraged ETFs, some industry voices are calling for a reassessment of the regulatory approach.
Researcher Seol Tae-hyun from DB Securities noted, "In prolonged weak markets, single-stock leveraged products can suffer losses exceeding those of the underlying stock due to volatility decay, making recovery more difficult. Rather than making emotional, additional purchases to cover losses, investors should formulate strategies based on data."
