South Korean financial authorities are considering a limit on the share of single-stock leveraged exchange-traded funds (ETFs) that can be held in individual investment portfolios.

The proposed measure aims to reduce concentration risk for retail investors who have increasingly turned to these high-volatility instruments.

The regulatory push follows growing concerns about market stability.

A leading Korean ETF issuer recently issued a rare public warning regarding the risks associated with single-stock leveraged products, highlighting the potential for significant losses in volatile market conditions.

This caution from industry players underscores the urgency felt by policymakers to address the rapid growth of these complex instruments among non-professional investors.

The move signals a deepening regulatory focus on retail trading behaviors in South Korea.
