Woofun AI reports that the Bank of Korea has submitted a document to the National Assembly highlighting risks associated with single-stock leveraged ETFs focused on Samsung Electronics and SK Hynix. The central bank noted that the rapid growth of these products may intensify structural herding behavior and volatility within the Korean equity market.

Data indicates that the combined market capitalization share of the two firms rose from approximately 36.1% at the end of last year to over 55% recently, while their trading volume share increased from 27.9% to 63.5%. Financial regulators have emphasized the necessity of monitoring these instruments for potential systemic risks, noting that shifting market sentiment could exacerbate unidirectional capital flows and price fluctuations through intraday rebalancing and derivative hedging mechanisms.
