South Korea Eyes New ETF Regulations as Leveraged Funds Face Increased Scrutiny

South Korea’s ETFs tracking single stocks are facing a fresh regulatory crackdown. Financial Services Commission Chairman Lee Eog-weon confirmed Thursday, July 16, 2026, that new measures on leveraged ETFs are coming soon. The announcement follows weeks of market turmoil tied to products built around Samsung Electronics and SK Hynix, Korea’s two largest chipmakers.

President Lee Jae-myung has already ordered regulators to prepare supplementary measures, escalating pressure on the Korea Exchange and Financial Supervisory Service. Here’s a full breakdown of what’s driving the scrutiny and what changes could follow.

South Korea’s ETFs: A Rapid Rise And Reversal

Single-stock leveraged ETFs tied to Samsung Electronics and SK Hynix launched on May 27, 2026. Sixteen products debuted with a combined $3 billion in assets, a figure that ballooned within weeks of trading.

• Combined market cap of 14 remaining ETFs: 13.02 trillion won, or $8.63 billion.
• Cumulative trading value in the first month: 212 trillion won.
• Peak assets under management across all 16 products: roughly $9.1 billion.
• Individual retail investors: approximately 92% of total ETF holders.

That scale of retail participation is unusual even by South Korea’s already retail-heavy market standards. It also explains why regulators moved so quickly once volatility spiked in June.

The June 22 Selloff That Triggered Alarm

Financial Supervisory Service Governor Lee Chan-jin publicly said on June 22, 2026, that he regretted approving these leveraged ETFs. Markets reacted violently to that admission within 24 hours.

• Certain leveraged ETFs fell more than 25% the day after Lee’s comments.
• The KOSPI triggered a full circuit breaker amid the plunge.
• Margin debt tied to these products hit roughly 60 trillion won, or $39 billion, by late May.
• US Nasdaq futures and global semiconductor stocks felt spillover pressure.

Governor Lee’s remarks effectively became the catalyst for the sell-off, not just commentary on it. That sequence has since shaped how cautiously officials are now discussing further regulatory steps.

South Korea's top financial regulator will announce new measures on single-stock leveraged exchange-traded funds soon, its chief said on Thursday, amid worries about the effects of such instruments on financial market stability. https://t.co/9yS7pKeW6k

Why South Korea’s ETFs Concentrate So Much Risk

Samsung Electronics and SK Hynix together represent more than 40% of the KOSPI index. Leveraged ETFs tracking these two stocks amplify that concentration through daily rebalancing of spot and futures positions.

• Daily rebalancing strategies mechanically increase buy or sell pressure on both stocks.
• The Bank of Korea has warned this can deepen concentration risk market-wide.
• Broader domestic leveraged ETF assets under management hit roughly $45 billion by early July.
• That figure represents close to 800% year-to-date growth across the category.

Regulators argue this concentration turns two stocks into a systemic pressure point for the entire index. That framing is central to why officials are now weighing curbs rather than just monitoring.

Political Pressure Adds Urgency To The Review

President Lee Jae-myung instructed Korea Exchange Chairman Chung Eun-bo and FSS Governor Lee Chan-jin on July 15 to prepare sound supplementary measures. That directive came less than two months after the products first listed.

• Presidential order issued: July 15, 2026, at a Blue House briefing.
• Ruling party’s K Capital Market Special Committee met July 13 to review the issue.
• FSS plans to meet asset management CEOs to discuss overheating in the sector.
• Listing of new individual stock weekly options was postponed amid the controversy.

Officials say hedge trading tied to managing these ETFs may be adding volatility to the underlying spot market. That concern now sits at the center of the FSC’s upcoming policy announcement.

Delisting Debate Divides Regulators And Industry

Some industry officials have floated delisting existing leveraged ETFs entirely to cool the overheated market. Korea Exchange officials, however, say the products don’t currently meet conventional delisting criteria.

• Delisting typically requires weak trading activity or insufficient assets under management.
• These ETFs remain highly liquid, making standard delisting grounds difficult to apply.
• Mirae Asset Global Investments and Samsung Asset Management run the largest of these products.
• Both asset managers would face reduced fee income under any forced delisting scenario.

FSC Chairman Lee Eog-weon has also ruled out a temporary trading suspension, warning it could cause a bigger side effect. That leaves targeted rule changes as the more likely near-term outcome.

Bottom Line

South Korea’s ETFs built around Samsung Electronics and SK Hynix have gone from a promising product launch to the center of a regulatory storm within seven weeks. Rapid asset growth, heavy margin debt, and a June circuit-breaker event pushed both the FSC and the president’s office into direct action.

With new measures expected soon and delisting still debated among industry officials, Korea’s leveraged ETF market faces its most consequential regulatory test since 2012. Investors exposed to Samsung Electronics, SK Hynix, or Korean equities broadly should watch this policy rollout closely.
