South Korea Suspends New Single-Stock Leveraged ETF Listings to Limit Market Volatility

South Korean financial regulators have announced a temporary halt on the new listings of single-stock leveraged exchange-traded funds (ETFs), targeting products tied to major technology giants Samsung Electronics and SK Hynix. This decisive move, unveiled Thursday by the Financial Services Commission (FSC), aims to stem volatility after a recent spike in popularity and trading of these financial instruments. The FSC specified that the moratorium on new listings will continue until market conditions stabilize, a response to repeated calls for stronger measures after sharp fluctuations in the country’s $4.1 trillion equity market. At the heart of this policy shift is concern over the outsized influence of single-stock leveraged ETFs, which have been linked to intensified market swings. In addition to the temporary listing ban, South Korea will increase the minimum deposit requirement for investors in leveraged ETFs from 10 million won to 30 million won (approximately $20,300), effective August 5. This announcement emerged after high-level discussions involving the FSC, South Korea’s finance ministry, and the central bank, all responding to growing anxiety from policymakers, notably following directives from President Lee Jae Myung. The move reflects a significant regulatory effort to bring order to what has become one of the world’s most turbulent equity markets in 2026. The sharper regulatory tone follows an extraordinary rally and subsequent selloff in the Korean market. On Thursday, the benchmark Kospi Index suffered a dramatic plunge exceeding 6%, with SK Hynix tumbling 10% and Samsung Electronics retreating by around 8%. Analysts attributed much of the volatility to constant rebalancing required by leveraged ETFs, which can amplify price movements in underlying shares. Authorities have acknowledged that approvals for these popular single-stock products may have come too rapidly, fueling a rise in retail trading with borrowed funds. At the end of May, stock margin borrowing by retail investors hit a record 60 trillion won ($40.39 billion). Despite recent turbulence, the South Korean equity market still boasts a robust performance so far in 2026, having surged by over 50% year-to-date.
