South Korean authorities will limit individual investments in single-stock leveraged ETFs to 20% of a person's total investment amount [1].
The move follows a period of extreme market instability that threatened the broader financial system. By restricting the volume of high-risk leveraged products, the government aims to prevent speculative trading from amplifying price swings during market downturns.
Deputy Prime Minister and Minister of Economy and Finance Gu Yoon-chul said the measures were announced during an emergency market situation review meeting held Wednesday at the Government Complex in Seoul [1]. The meeting included Bank of Korea Governor Shin Hyun-song, Financial Services Commission Chairman Lee Eok-won, Financial Supervisory Service Governor Lee Chan-jin, and Presidential Secretary for Economic Growth Ha Jun-kyung [1].
The intervention comes after the KOSPI experienced two consecutive days of sharp declines [1]. This volatility pushed the index below the 6,000 point level [1]. Officials said single-stock leveraged ETFs were a primary driver of this increased volatility, noting that these instruments can create feedback loops that accelerate market crashes.
Beyond the individual investment caps, the government said it will establish a legal basis to implement market stabilization measures during emergency situations [1]. This framework would allow regulators to intervene more decisively if specific financial instruments pose a systemic risk to the national economy.
The government intends to manage the total volume of these ETFs to ensure that individual portfolios remain diversified, and less exposed to the extreme risks associated with leveraged single-stock bets [1].

This regulatory shift signals a transition from a laissez-faire approach to high-risk retail trading toward a more interventionist 'guardrail' system. By capping leveraged exposure, South Korea is attempting to decouple individual retail speculation from systemic market stability, recognizing that the hyper-concentration of leveraged bets in single stocks can trigger rapid, cascading sell-offs that threaten the entire index.
