TL;DR
- FSS chief Lee Chan-jin said South Korea accelerated review of single-stock leveraged ETFs to meet launch schedule before 16 products debuted May 27.
- Lawmakers said the FSS began its review before the Korea Exchange completed its preliminary process, a sequencing Lee indicated appeared unprecedented.
- Regulators later halted new listings and raised trading requirements as investor losses mounted, while Lee framed his criticism around investor protection.
South Korea’s Financial Supervisory Service chief Lee Chan-jin said the review of single-stock leveraged ETFs was accelerated to meet a launch schedule. In a report on his National Assembly testimony, Lee said regulators moved quickly after the Financial Services Commission announced a timetable in mid-April. The products went live on May 27. For investors comparing ETFs and other exchange-traded products, the admission raises questions about how investor-protection reviews were sequenced before a high-risk product reached the market.
FSS Review Ran Before Exchange Preliminary Process Was Complete
The controversy centers on 16 leveraged ETFs linked to Samsung Electronics and SK Hynix. Normally, listings undergo a preliminary Korea Exchange review before an FSS review, but lawmakers said the FSS began its work before the exchange completed that first stage. Asked whether that sequence had happened previously, Lee said checks indicated it appeared to be the first time. The episode adds context to scrutiny around leveraged investment products. Lee attributed the accelerated process to meeting the announced launch timetable rather than saying ordinary review requirements were intentionally abandoned.

The products later generated investor-protection concerns as retail participation and losses increased. FSS data cited in the reference showed 2.3242 trillion won in realized trading losses across 10 financial investment firms between May 27 and August 14. Regulators stopped new single-stock leveraged ETF listings on July 16 and later raised the minimum cash requirement for trading them from 10 million won to 30 million won. Similar leverage risks have surfaced through crypto-linked ETF exposure. Those subsequent measures show regulators tightened access after launch, but they do not establish that the expedited review caused investor losses.
Lee had already expressed regret about introducing the products at a June 22 press briefing, later clarifying that his comments concerned investor protection. He said single-stock leveraged ETFs differ from index-tracking funds because they lack diversification and can magnify volatility in the underlying shares. The debate also fits South Korea’s broader push to expand ETF offerings while balancing market development with retail safeguards. The latest testimony confirms that schedule pressure influenced the review process, while questions over responsibility and whether the accelerated sequence weakened oversight remain part of the political and regulatory dispute.
