South Korean Stocks Spiral 16% in Two Days as Retail Investors Flee Market

South Korea's benchmark equity index plummeted for a second consecutive session Wednesday, deepening a historic monthly rout that has wiped out a record 33% of the Kospi's value and left the nation's vast army of retail investors reeling.

The two-day selloff accelerated as individual investors — who dominate trading volume in Seoul — rushed to exit positions amid mounting fears over the global economic outlook and tightening financial conditions. The Kospi's decline this month marks its steepest monthly drop on record, surpassing even the depths reached during the 2008 financial crisis and the pandemic panic of March 2020.

Despair has gripped online investing communities where millions of Korean retail traders congregate, with many reporting catastrophic losses on leveraged positions. The selling pressure has been so intense that it triggered circuit breakers and forced the financial regulator to impose temporary short-selling restrictions in a bid to stabilize the market.

Analysts say the rout reflects a perfect storm: aggressive Federal Reserve tightening, a slowing Chinese economy, and a tech-heavy index disproportionately exposed to the global semiconductor downturn. Foreign investors have also been net sellers for weeks, compounding the exodus.

According to Bloomberg, the scale of retail capitulation underscores the structural vulnerability of a market where households hold a larger share of equities than in any other major economy.
