The stricter rule will cover domestic and overseas products tied to names including Samsung Electronics, SK Hynix, Tesla and Nvidia, while substitute collateral will no longer count toward the minimum deposit.
South Korea will require investors to hold 30 million won ($21,700) in cash to buy new or additional positions in single-stock leveraged ETFs and ETNs starting July 31, tripling the current 10 million won ($7,200) threshold. The new standard, announced by the Financial Services Commission, the Financial Supervisory Service and the Korea Exchange, also removes substitute collateral such as stocks, ETFs and bonds from deposit calculations. The tighter rule applies to all domestic and overseas single-stock leveraged products, including those tied to Samsung Electronics, SK Hynix, Tesla and Nvidia. Authorities brought forward the timeline after funds flowed quickly into the products and after coordinating implementation schedules with securities firms and system developers. Existing investors may keep or sell current holdings, but they must also meet the new cash requirement for any additional purchases.
