Under pressure from significant retail capital outflows to similar overseas products, South Korean regulators have completed a major policy shift, with the first single-stock leveraged ETFs set to debut on May 27.
Sixteen 2x leveraged and inverse ETFs based on Samsung Electronics and SK Hynix will be listed on the South Korean stock market this Wednesday. They are issued by eight asset management companies: Samsung Asset Management, Mirae Asset, Korea Investment & Securities, KB, Shinhan, Hanwha, Kiwoom, and Hana.
The direct backdrop for this launch is that Hong Kong-listed leveraged ETFs tracking these two chipmakers have attracted $2.6 billion in inflows this year. Regulators aim to redirect this trading activity back to the domestic market. Mirae Asset Securities analysts estimate the new domestic funds could attract up to 5.3 trillion won (approximately $3.5 billion).
However, analysts have issued clear warnings about market stability. Given that Samsung Electronics and SK Hynix together account for nearly half of the Kospi index's market capitalization, the daily mechanical rebalancing required by leveraged products could further amplify market volatility and exacerbate index concentration risks.
**Regulatory Shift: From Long-Term Ban to Conditional Opening**
The launch of these products marks a significant policy change by the Financial Supervisory Service (FSS). Documents disclosed by South Korean financial regulators show that the agency had long prohibited trading in such products due to diversification requirements, previously stipulating a maximum investment limit of 30% in a single underlying asset and requiring indices to be composed of at least 10 constituent stocks.
South Korea formally revised the relevant rules on April 28, allowing the issuance of single-stock leveraged ETFs based on leading domestic companies. The new regulations simultaneously raised the maximum investment limit for a single stock to 100% and removed the requirement for fund portfolios to contain at least 10 stocks. Only Samsung Electronics and SK Hynix have been approved as underlying assets this time, with regulators setting strict entry criteria, limiting the number of eligible stocks.
The core driver behind this shift is the massive exodus of domestic investors. In the first two months of this year, the number of investors who completed mandatory training for leveraged ETF investment reached 300,000, surpassing the total for all of 2025, highlighting strong market demand. By allowing these funds to list domestically, regulators aim to simultaneously implement domestic investor protection and monitoring mechanisms.
**Semiconductor Boom Provides Fundamental Support**
The strong performance of the two companies this year provides a market foundation for related products. Driven by AI server demand, memory chip prices have continued to rise this year, with both Samsung Electronics and SK Hynix posting record quarterly earnings in Q1. As of May 25, Samsung Electronics and SK Hynix have surged by 143.95% and 198.67% year-to-date, respectively, maintaining high market attention.
Chan H Lee, Executive Partner at Petra Capital Management in Seoul, stated, "While the current enthusiasm for AI-related semiconductor stocks is supported by strong fundamentals, the increased use of leveraged products and the growing concentration of market leadership could exacerbate short-term volatility."
**Daily Rebalancing Mechanism Raises Volatility Concerns**
Market participants have expressed clear concerns about the structural risks of leveraged products. These products require daily mechanical buying and selling to rebalance and maintain target exposure. This process, unrelated to company fundamentals, directly amplifies market fluctuations.
Barclays estimated that during the sell-off on May 15, rebalancing trades accounted for 17% of SK Hynix's trading volume. UBS Group noted that during the final hour of trading on March 3, when the stock price fell over 10%, rebalancing flows made up 60% of SK Hynix's volume.
Jung In Yun, CEO of Fibonacci Asset Management Global in Singapore, warned, "These ETFs will exacerbate the existing problem—concentration risk. This presents a structural issue for long-term investors because the volatility of the index will remain elevated."
**Regulators Issue Dense Risk Warnings, Investment Thresholds Raised**
Facing potential risks, South Korean regulators have implemented a series of investor protection measures ahead of the product launch. On May 15 and 25, the financial authorities issued investment guidelines twice, emphasizing the fundamental differences between these products and ordinary ETFs.
Regulators pointed out that under the leverage effect, the 30% daily limit on single-stock price movements could be amplified to a theoretical maximum loss of 60%. In volatile markets, the negative compounding effect would continuously erode principal. Furthermore, due to the products' high volatility, significant deviations between market price and net asset value may occur. Notably, the product names are prohibited from using the term "ETF" to distinguish them from traditional diversified investment products.
Investor participation thresholds have also been raised. Requirements include a base margin of 10 million won and completion of a total of two hours of investor education courses. Data shows that approximately 100,000 people registered for related training between April 28 and May 21.
