South Korea Moves to Curb ETF-Driven Market Swings

Finance Minister Koo Yun-cheol told a cabinet meeting on Tuesday that authorities would act to reduce stock market volatility. His comments came after retail trading in single-stock leveraged exchange-traded funds cooled following fresh restrictions.

South Korea adopted more controls last week after earlier steps failed to slow demand for the risky products. One measure could limit single-stock leveraged ETFs to 20% of an individual investor’s total investment assets.

The products had drawn heavy retail interest during a sharp rally in chip-linked stocks. However, recent market losses raised concern that leveraged products could magnify losses during fast sell-offs.

Authorities are now moving to enforce the new rules quickly. The government’s focus remains on reducing disorderly trading and limiting risks for retail investors using leveraged exposure.

Trading Volumes Fall After New Curbs

Daily trading volume in the TIGER SK Hynix single-stock leveraged ETF fell to 291 billion won on Monday. That compared with 482 billion won on Friday and a much higher level a day earlier.

The TIGER Samsung Electronics single-stock leveraged ETF also recorded a sharp slowdown. Daily trading volume fell to 234 billion won on Monday from 511 billion won on Friday and 1.4 trillion won on Thursday.

The two ETFs had been among the most active products in the market. Their trading volumes reached late-June peaks of 3.9 trillion won and 3.6 trillion won, respectively.

Han Ji-young, an analyst at Kiwoom Securities, said the decline in activity may have helped reduce daily swings. He said, “It seems to have contributed to a decrease in daily volatility in the KOSPI market to some degree.”

Retail Losses Add Pressure on Policymakers

Retail investors have faced heavy losses after South Korea’s stock market pulled back from its June peak. The KOSPI had rallied strongly on demand for chipmakers tied to the artificial intelligence boom.

That reversal has placed pressure on President Lee Jae Myung’s administration. His approval rating fell to 44.5% on Monday, near its lowest level since he took office last year.

Retail investor groups have criticized the government after margin calls and losses hit leveraged positions. Jung Eui-jung, head of the Korean Stockholders’ Alliance, said, “Our chat rooms are filled with criticism of President Lee.”

President Lee had tied part of his economic agenda to the stock market. During his campaign, he pledged to push the KOSPI toward 5,000 by the end of his presidency in 2030.

KOSPI Outlook Remains Tied to Chip Stocks

South Korea’s market remains closely linked to semiconductor names such as Samsung Electronics and SK Hynix. These stocks have been central to investor interest in AI-related growth.

The recent drop in ETF trading suggests the latest restrictions may be cooling speculative activity. However, analysts said more time is needed to assess whether the measures can bring steadier trading.

Single-stock leveraged ETFs can increase gains when markets rise but can also deepen losses when prices fall. That risk has become more visible after the recent tech sell-off.

South Korea’s next challenge is balancing investor protection with market growth. Traders will now watch ETF flows, margin activity, and KOSPI swings as the new curbs take effect.
