I. Potential Risks and Their Detonation
1. Hasty Policy Launch and Low Entry Barriers Create Hidden Dangers
① Rapid Policy Implementation: Driven by high-level officials in South Korea in January 2026, 16 single-stock leveraged ETFs were launched on May 27th, less than five months after the initial proposal.
② Highly Concentrated Risk: Due to market capitalization and trading volume thresholds, all products track only two stocks, Samsung Electronics and SK Hynix, resulting in highly concentrated risk.
③ Low Entry Barriers Create Hidden Dangers: Initial margin is only 40%, and 70% can be offset by stocks, meaning only 3 million won in cash is required to operate, far lower than similar overseas products.
2. Retail Investor Influx and Rapid Bubble Expansion
① Explosive Growth in Scale: Retail investors poured in after the products' launch, reaching approximately 12.4 trillion won in assets under management by mid-July.
② Misjudgment of Long-Term Holding: Most retail investors viewed leveraged ETFs as long-term investment tools, not short-term trading tools, ignoring the depreciation mechanism caused by daily rebalancing.
③ Strong Buying Sentiment: During the earlier rally in the semiconductor sector, leveraged products amplified returns, further attracting speculative capital.
3. Backlash Begins, Chain Reaction
① Negative Feedback Cycle: The "daily rebalancing" mechanism of leveraged ETFs triggered a "sell on dips" spiral effect during market declines, which in turn suppressed the performance of the underlying stocks.
② Broken Circuit Breaker and Trading Suspension Records: Since the beginning of the year, the South Korean stock market has triggered circuit breakers 8 times (the historical total is only around ten times) and had at least 37 temporary trading suspensions (far exceeding the 26 times recorded during the 2008 financial crisis).
③ Massive Liquidation: Between May and July 14, forced liquidations amounted to 2.3 trillion won; on July 13 alone, over 1.2 million retail accounts reached the margin call threshold; between July 1 and 10, approximately 320,000 to 460,000 accounts were forcibly liquidated.
④ Top Products Halved in Value: The KODEX SK Hynix single-stock leveraged ETF has fallen over 60% from its June high, and Southern's double-leveraged Samsung Electronics and SK Hynix products have also halved in value from their peaks.
4. Regulatory Admission of Error and Emergency Intervention
① Regulatory Admission of Error: On June 22, Lee Chan-jin, head of the Financial Supervisory Service of Korea, publicly stated, "I deeply regret not being able to stop its launch," admitting that the approval process was "too hasty."
② Presidential Intervention: On July 15, South Korean President Lee Jae-myung directly named leveraged ETFs, demanding "swift and appropriate supplementary countermeasures."
③ "F4" Finalizes Measures: On July 16, the "F4" high-level coordination mechanism, composed of the Ministry of Finance and Economy, the Financial Services Commission, the Bank of Korea, and the Financial Supervisory Service, held a market situation review meeting and will make a formal decision on relevant countermeasures.
II. Seven Emergency Tightening Measures
1. Capital Threshold: The minimum deposit has been raised from 10 million won to 30 million won, and must be in cash (stock collateral is no longer accepted). 2. Trading Rules: The minimum trading unit has been adjusted from 1 share to 20 shares.
3. Risk Control and Supervision: ① The obligation to manage premium/discount rates has been tightened from 3% to 2%; ② The risk designation process has been shortened (from 3 stages to 2 stages); ③ New product listings by companies operating in violation of regulations are restricted.
4. Product Supply: The listing of new single-stock leveraged products is suspended, and advertising and marketing of existing products are prohibited.
5. Investor Education: Mandatory training hours have been extended from 2 hours to 3 hours.
III. Market Impact
1. Inki Cho, Senior Financial Market Strategist at Exness, an online trading platform: The intervention by the Korean Financial Services Commission (FSC) was "long overdue" and is a correction of known policy mistakes. However, if the measures are too aggressive, they may trigger investors to exit prematurely, exacerbating short-term volatility. In the medium to long term, this will help improve market credibility.
2. Jason Minsang Kam, Head of Active Equity Management at Kyobo Life Insurance in Korea: Stricter entry standards will limit retail investors' participation in high-leverage products, which, from an investor protection perspective, will help smooth out short-term market volatility.
