The Bank of Korea warns that Samsung Electronics and SK Hynix single leverage ETF amplify stock market risks

According to a document submitted by the Bank of Korea to the South Korean National Assembly, a single stock leveraged ETF targeting Samsung Electronics and SK Hynix has rapidly expanded. The market value of the two companies has increased from about 36.1% at the end of last year to over 55%, and their turnover has increased from 27.9% to 63.5%. The Bank of Korea has warned that this phenomenon has increased the structural risks and volatility of the South Korean stock market. The South Korean financial regulatory agency emphasizes the need to monitor the impact of related products on market stability and systemic risks. A single target leveraged ETF exacerbates one-way capital flow under changes in market sentiment, and amplifies price fluctuations when the market reverses through intraday rebalancing and derivative hedging mechanisms.
