6 Weeks After Approving 2x, Investors Are Demanding 3x: Why Retail Investors Are Buying KOSPI 3x Leverage ETFs in the U.S. — and 5 Key Debates Over Domestic Approval
Just six weeks after Korea's Financial Services Commission announced proposed rule changes (Jan. 30–Mar. 11) to allow 2x single-stock leverage ETFs, retail investors have been aggressively buying 3x KOSPI-tracking leverage ETFs on U.S. markets, reigniting the debate over domestic approval. While the Korea Exchange signaled in a Bloomberg interview that it is reviewing a gradual approval pathway, financial regulators maintain a cautious stance — sustaining a tense standoff between investors and the regulatory establishment.
The core of this story: The FSC drew the line at '2x,' but investors are already buying KOSPI at '3x' through the U.S. market. The paradox of regulatory asymmetry — which is driving capital outflows rather than preventing them — has resurfaced.
TL;DR
- In late January 2026, the Financial Services Commission (FSC) pre-announced a Capital Markets Act enforcement decree amendment to allow domestic listing of 2x single-stock leverage ETFs (comment period: Jan. 30–Mar. 11).
- However, the FSC maintained its position that 3x leverage will not be permitted.
- In response, retail investors have been aggressively buying Direxion Daily MSCI South Korea Bull 3X (KORU) and similar 3x KOSPI-tracking ETFs listed on U.S. markets.
- The Korea Exchange (KRX) Chairman signaled in a Bloomberg interview that gradual approval of high-multiple ETFs is under review, reigniting the debate.
- On March 3, JoongAng Ilbo and Herald Economy reported that the government is re-examining approval of 3x products, renewing the controversy.
The Facts: What Happened
The FSC Opens the Door to 2x — and Draws the Line at 3x
On January 30, 2026, the FSC pre-announced an amendment to the Capital Markets Act enforcement decree permitting the listing of 2x single-stock leverage ETFs on domestic blue chips such as Samsung Electronics and SK Hynix, as part of broader ETF market regulatory reform. The comment period runs through March 11.
FSC Chairman Lee Uck-won clearly stated, "We have no intention of allowing 3x leverage." He cited the fact that even the U.S. has restricted new listings of ETFs exceeding ±2x leverage since October 2020.
Retail Investors Were Already Moving at '3x'
The problem is that individual investors have already been jumping past domestic regulations to buy 3x in the U.S. market first.
- Herald Economy (as of Feb. 26): Amid the KOSPI rally, retail investors have been aggressively net-buying Korean 3x leverage ETFs listed in the U.S. (e.g., KORU). While the KOSPI rose 27.43% over the past month, those ETFs surged 99.27%.
- Seoul Economic Daily (Feb. 18): Retail investor U.S. ETF holdings surpassed ₩61 trillion. Preference for 3x leverage products such as TQQQ and SOXL continues.
- Korea Economic Daily (Feb. 12): Nasdaq 3x ETF TQQQ was the top net-buy, with ₩218.4 billion wagered in a single week.
With indirect offshore investment already normalized, the paradoxical regulatory asymmetry — where domestic investors are barred from what they can freely buy abroad — is now fully exposed.
Why the 3x Debate Is Erupting Now
The 'Faster Returns' Psychology of the KOSPI 5000+ Era
With the KOSPI surpassing 5,000 points and trading at all-time highs, retail investors who have already witnessed the rally are increasingly turning to leverage as a tool to maximize additional gains.
A Shinhan Investment Securities analyst noted: "Retail money is flowing in after the market has already risen, not in anticipation of a cheap entry."
The Mar. 11 Comment Period Deadline as Catalyst
The FSC's 2x ETF comment period closes on March 11. As the market anticipates the regulation to be finalized and implemented shortly after, it is already positioning to front-run 'the next step (3x).'
KRX Chairman's Bloomberg Remarks
KRX Chairman Jeong Eun-bo's Bloomberg interview statement — "We are reviewing a plan to gradually allow high-risk, high-multiple ETF products" — effectively served as a starting gun. It revealed a visible temperature gap between the FSC and the Exchange.
5 Key Debates
1. Regulatory Asymmetry Is Fueling Capital Outflows
Retail investors are already buying the 3x leverage they cannot get domestically — in the U.S. market. The argument that this capital would have supported the KOSPI had it been allowed to stay domestic is gaining traction.
2. The Volatility Decay Dilemma and Investor Protection
Leverage ETFs carry a structural risk: the 'negative compounding (volatility decay)' effect means long-term holders can incur losses exceeding the underlying asset's drawdown. These products are designed as short-term trading instruments, yet retail investors tend to hold them long-term.
3. International Alignment with the U.S.
Since the U.S. has also restricted new listings of ETFs exceeding ±2x since 2020, there is a counterargument that global standards are not favorable to 3x. However, high-multiple products are listed in Hong Kong and the UK, so there is no consistent international benchmark.
4. Volatility Risk for Samsung Electronics & SK Hynix
If domestic 3x single-stock leverage is permitted, there are concerns that algorithmic trading concentration in Samsung Electronics and SK Hynix could sharply amplify volatility.
5. The Political Economy: Market Stimulus vs. Financial Stability
For the government, allowing 3x leverage ETFs would deliver a short-term market boost, but controlling a potential bubble once formed becomes exceedingly difficult — a double-edged sword. There is also room for political calculations aligned with electoral cycles.
Context and Background
The Return of Retail Investors to the Domestic Market
In early 2025, retail investors' direct U.S. investment volume was approximately $87 billion per month; by end of February 2026, it had dropped to $46.5 billion — a 47% plunge. Over the same period, domestic retail investor trading volume rose from ₩507 trillion to ₩753 trillion — up 48.5% (Shinhan Investment Securities). The KOSPI rally is the driving force behind this capital repatriation.
In this context, domestic approval of 3x leverage ETFs is emerging as the final card to retain the last remaining offshore retail investors.
KB Asset Management's Preemptive Move
On February 26, KB Asset Management launched a pension-eligible ETF allocating 25% each to Samsung Electronics and SK Hynix, with 50% in bonds. While not a direct leverage product, asset managers are accelerating their efforts to capture concentrated investment demand.
Outlook: Will 3x Be Approved?
Short-term (H1 2026): After the FSC comment period closes (Mar. 11), the market is likely to watch the 2x ETF regime take root before any 3x decision. A rapid shift to 3x approval is not expected.
Medium-term (H2 2026–2027): Given the KRX Chairman's Bloomberg remarks and political pressure, substantive discussions on gradual approval could gain momentum. However, if global financial market volatility escalates (e.g., the Iran situation, Hormuz closure), the pace of deregulation could slow.
