Kim Yong-beom, Presidential Office Policy Director, is implementing emergency restrictions on South Korea's single-stock leveraged ETF market two months after the products launched on May 27. The regulatory tightening follows rapid market expansion to 11.9 trillion won by July 15 and excessive investment concentration in Samsung Electronics and SK Hynix, which together account for 52% of KOSPI market capitalization as of July 15. Kim initially championed the products by citing their availability in US markets, but concerns emerged that short-term speculative capital clustering in a few stocks amplified market volatility rather than achieving the stated policy goals of repatriating overseas investment demand and strengthening investor protection.
Single-Stock Leveraged ETF Market Expands to 11.9 Trillion Won in Two Months
Single-stock leveraged ETFs and ETNs (Exchange Traded Notes) first launched in South Korea on May 27. The 16 products grew from an initial market capitalization of 4.4 trillion won to 11.9 trillion won by July 15, a 2.7-fold increase in under two months. Daily trading volume increased from 10.4 trillion won on the first day to 13 trillion won on July 15.
Investment concentrated heavily in Samsung Electronics and SK Hynix-related products. The two stocks' combined share of total KOSPI market capitalization rose from 34% at year-end to 52% by July 15. Regulators cited concerns that leveraged and inverse products amplified volatility in both the underlying assets and the broader index.
The products require continuous rebalancing to track daily returns at a fixed multiple of the underlying asset. Liquidity providers (LPs) conduct trades to manage the gap between ETF market price and net asset value (NAV), with concentrated buying and selling in the final 30 minutes before market close. Kim stated on July 19 that this concentration of LP activity to manage tracking error could generate market shocks.
Regulators Raise Deposit Requirement to 30 Million Won and Ban New Listings
Authorities announced a package of restrictions covering new supply, entry barriers, and trading practices. New listings of single-stock related products including inverse and covered call variants will be suspended until market conditions stabilize. Advertising and promotional events for existing products are banned immediately.
The basic deposit requirement for individual retail investors will increase from 10 million won to 30 million won starting August 5. Currently, investors can use 70% of the appraised value of substitute securities including stocks, ETFs, and bonds to meet the deposit threshold, but from August 19 only cash deposits will be accepted.
Existing investors must maintain cash deposits of at least 30 million won each time they purchase additional single-stock leveraged products. The same deposit rules apply to overseas-listed single-stock leveraged products.
The minimum trading unit for domestic single-stock leveraged products will increase from 1 share to 20 shares starting in November, following securities firms' system development. Mandatory investor education will extend from 2 hours to 3 hours, with enhanced content covering actual loss cases and strengthened assessments.
The LP tracking error management standard for domestic ETFs and ETNs will tighten from 3% to 2%. Regulators plan to restrict new LP business for securities firms that violate this standard through willful misconduct or gross negligence.
Kim Yong-beom Acknowledges Policy Dilemma as Market Reaches 10 Trillion Won
Kim promoted the products during the introduction phase by emphasizing their availability in US markets, arguing that blocking domestic products would only drive capital outflows as investors accessed overseas markets. The policy rationale centered on bringing demand into the domestic regulated framework to enhance capital market competitiveness and product diversity.
On July 19, Kim stated that delisting products with over 10 trillion won in assets and existing investor positions would itself create enormous market shock. A senior financial industry executive commented that the policy appears to have opened the market first to promote activity, then raised entry barriers significantly after faster-than-expected growth, questioning whether initial policy design adequately considered market impact and investor protection levels.
