South Korea’s KOSPI Halts Trading as Tech Selloff Triggers Circuit Breaker
South Korea's KOSPI index triggers a circuit breaker following an 8% plunge. Tech giants Samsung and SK Hynix lead the decline amid global market fears.
POLICY WIRE — Seoul, South Korea — South Korea’s benchmark KOSPI index plummeted by 8% on Thursday, forcing a temporary halt in trading as a massive selloff swept through the technology sector.
The market-wide circuit breaker was activated for the first time in two and a half months as the index dropped to 5,528.05, marking its lowest level since July 29. The decline was fueled by a broader global retreat in semiconductor stocks, with major industry players Samsung Electronics and SK Hynix bearing the brunt of the losses.
Investors are currently grappling with a confluence of negative pressures, including concerns over AI infrastructure financing, elevated semiconductor valuations, and intensifying competition from Chinese memory-chip manufacturers. The downturn was further exacerbated by persistent U.S. inflation data, which has reignited market anxieties regarding potential interest rate hikes.
The volatility in Seoul mirrors a wider trend across Asian markets, where traders have aggressively exited positions in previously high-performing chipmakers. The market remains on edge as participants assess the impact of the global tech rout and the implications of recent developments, such as the IPO of China’s CXMT.
