South Korea Bans New Leveraged ETF Listings as KOSPI Slides 27% From June Peak
3 articles · Updated · Korea Economic Institute of America · Jul 22
Summary
July 17 brought tighter South Korean rules on single-stock leveraged products and a temporary halt to new leveraged ETF listings tied to major tech names as authorities moved to curb market swings.
Those curbs followed a volatility spike after single-stock leveraged ETFs tracking Samsung Electronics and SK Hynix launched in May; the KOSPI Volatility Index topped its 2008 crisis peak and circuit breakers were triggered seven times in 2026.
Leveraged ETFs have grown into a major force in the rally, making up about one-fifth of Korea’s 1,142 ETFs, while ETF daily turnover jumped to KRW 34 trillion in June from KRW 6.6 trillion in December.
The broader boom was fueled by AI chip demand and governance reforms: Samsung and SK Hynix now represent 55.5% of KOSPI market value, helping drive a near doubling in the index before its 27% pullback.
The clampdown underscores a wider concern that Korea’s market and economy are increasingly concentrated in two chipmakers and one sector even as the government still targets 3.0% GDP growth in 2026.
Can Seoul's market reforms survive the fallout from the retail investor losses they helped create?
Has the AI chip boom revealed a fatal flaw in South Korea's economic strategy?
After a 27% KOSPI Plunge: South Korea’s Emergency Ban on Leveraged ETFs and the Retail Investor Reckoning
Overview
In July 2026, South Korea faced a sharp market downturn as the KOSPI index dropped over 27% from its peak, prompting urgent action from financial authorities. On July 16, top policymakers held an emergency meeting and the Financial Services Commission quickly announced a temporary ban on new single-stock leveraged ETFs. They also stopped advertising for these risky products and introduced stricter safeguards to protect investors. These measures aimed to stabilize the market and address the heavy losses suffered by retail investors, who were highly exposed to leveraged products during the crisis.
