President Lee Jae Myung urges South Korean financial authorities to quickly prepare complementary follow-up measures addressing risks associated with recently introduced single-stock leveraged exchange-traded funds (ETFs) tied to Samsung Electronics and SK hynix. Speaking at a policy briefing at Cheong Wa Dae, Lee says authorities should prepare “prompt” and “well-crafted” measures, citing growing criticism that the ETFs have contributed to increased volatility in the domestic stock market. The ETFs, introduced in May, track the daily performance of the two companies and use leverage intended to magnify short-term price movements. Samsung Electronics and SK hynix together account for roughly half of the Korea Composite Stock Price Index (KOSPI) total market capitalization, and policymakers have pointed to the products as one factor behind swings in the benchmark index. Lee instructs relevant agencies, including the Financial Services Commission (FSC) and the Financial Supervisory Service (FSS), to develop the measures, after earlier comments by senior officials, including the finance minister, raised concerns about potential side effects of the ETFs. The government reviews are framed as risk-management steps in response to market criticism of the products.
