Summary of South Korea's New Regulations on Single-Stock Leveraged ETFs
On July 23, 2026, South Korea's Financial Services Commission (FSC) announced significant changes to the regulations governing single-stock leveraged exchange-traded funds (ETFs) and exchange-traded notes (ETNs). These changes are aimed at tightening access for retail investors in response to rapid market growth.
Key Changes to Regulations
- Increased Cash Requirement: The minimum cash requirement for retail investors purchasing single-stock leveraged ETFs and ETNs will rise from KRW 10 million (approximately $7,200) to KRW 30 million (around $21,600). This change will take effect on July 31, 2026, ahead of the previously planned schedule.
- Cash-Only Requirement: Under the new rules, only cash deposits will qualify towards the minimum requirement. Non-cash collateral such as stocks, ETFs, and bonds will no longer be accepted.
- Scope of Regulations: The new rules apply to all single-stock leveraged products, both domestic and those listed on overseas exchanges, including popular stocks like Samsung Electronics, SK Hynix, Tesla, and Nvidia.
- Existing Investors: Current investors must also meet the new KRW 30 million cash threshold if they wish to increase their positions. However, selling existing holdings will not require meeting this minimum cash requirement.
- System Upgrades for Securities Firms: Securities firms that cannot complete necessary system upgrades by the deadline may be instructed to restrict new purchases of affected products.
Market Growth and Regulatory Response
The decision to implement these stricter regulations comes after a remarkable expansion of South Korea's single-stock leveraged ETF market. Since their introduction on May 27, 2026, the market capitalization of these products surged from KRW 4.4 trillion to KRW 11.9 trillion by mid-July, marking a growth of over 170% in just two months. Daily trading volumes also increased significantly during this period.
Changes to Cash Calculation
The new framework will also alter how qualifying cash is calculated. Currently, proceeds from stock sales can be counted towards the minimum deposit on the day of the trade. Under the revised rules, these proceeds will only qualify after settlement, which occurs on a T+2 basis. Additionally, loans secured against proceeds from stock sales will be excluded from the minimum cash calculation.
Future Regulatory Measures
These changes are part of a broader regulatory effort to mitigate risks associated with single-stock leveraged products. Other measures under consideration include:
- Suspension of new leveraged product launches and prohibition of related advertising.
- Tightening tracking error standards from 3% to 2% and increasing penalties for violations.
- Potential increase in the minimum trading unit from one unit to 20 units.
- Reducing the number of liquidity providers and widening bid-ask spreads.
- Lowering the maximum leverage ratio from 2x to around 1.5x.
These measures indicate that regulators are prepared to implement further restrictions if speculative activity in the market remains high.
