South Korea’s US$1.7 Billion Leveraged ETF Loss Exposes Retail Product Risk

Seoul, 7 October 2026 – South Korean retail investors are estimated to have lost 2.3 trillion won, or about US$1.7 billion, from leveraged exchange-traded products linked to the country’s two largest chipmakers, providing a stark test of whether product design, disclosure and investor safeguards have kept pace with speculative demand.

The estimate was compiled from brokerage data by the Financial Supervisory Service and provided through a lawmaker’s office. The products magnified daily movements in Samsung Electronics and SK Hynix, companies that sit at the centre of the global memory and artificial-intelligence supply chain. Leverage can double gains over a single session, but compounding, volatility and financing costs can produce losses that diverge sharply from an investor’s longer-term view of the underlying shares.
