Leveraged ETF trading in South Korea has dropped to 4% of its peak volume in June, reflecting both the recent market selloff and tighter investor onboarding rules.

The decline highlights how regulatory requirements are reshaping participation in higher-risk exchange-traded products, with cumbersome compliance steps weighing on trading volumes alongside weaker market sentiment.
