South Korea's KOSPI Slumps 30% as Leveraged ETFs Deepen Retail Investor Trauma
1 articles · Updated · Yahoo Finance · Aug 21
Summary
A 30% slide in South Korea's KOSPI since its June 19 peak has left retail investors reeling, turning a market reform drive into a political and social problem for President Lee Jae Myung's government.
The damage traces to regulators' May 27 approval of single-stock leveraged ETFs, pushed as a way to narrow the "Korea Discount" even though officials had raised concerns that local investors did not fully grasp the risks.
Entry barriers were light — a one-hour training course and a 10 million won ($7,208) minimum deposit — helping funnel retail traders into complex products that magnified losses as sentiment flipped from euphoria to gloom.
The fallout is spreading beyond paper losses: demand for psychiatric help is rising, and police in Busan arrested a man in his 20s over the attempted murder of a YouTuber he allegedly blamed for stock losses.
The episode is also reviving doubts about South Korea's market structure and whether a tech powerhouse with such extreme retail trading behavior can credibly advance toward developed-market status.

Overview
In mid-2026, South Korea’s KOSPI stock index soared to record highs, driven by retail investors and global excitement over AI and semiconductor giants. After regulators approved single-stock leveraged ETFs, retail investors poured in massive amounts of borrowed money, creating a fragile, debt-fueled rally. When global sentiment shifted and competition fears rose, the KOSPI crashed 41% in just 40 days. The sharp fall triggered a destructive cycle of forced ETF selling and margin calls, wiping out billions in retail savings—especially among young investors. Public outrage forced regulators to crack down, but trust in the market remains badly shaken.
