South Korea’s KOSPI Triggers Circuit Breaker After 8% Drop as Margin Loans Hit Record $24.7 Billion
South Korea’s KOSPI triggered a 20-minute trading halt after tumbling more than 8% at the open, with the benchmark briefly down 8.8% and at 7,445.1 as Samsung Electronics slid 10% and SK Hynix dropped 11%. The fall extended Friday’s 5.5% retreat in a market already hit by a broad selloff in artificial-intelligence-linked chip stocks.
The decline comes as leverage in the market has climbed sharply. Margin loans in South Korea rose to a record 38 trillion won ($24.7 billion) on May 29, up 39% from 27.3 trillion won at the end of 2025 and more than doubled over the last 12 months, increasing the risk of forced liquidations if prices keep falling. Earlier selling had also been linked to foreign outflows and fund rebalancing after a stronger-than-expected US jobs report reduced expectations for Federal Reserve rate cuts.
