South Korea’s KOSPI plunged 8.8%, dropping back below the 5,000-point milestone and triggering a circuit breaker that halted trading for eight minutes. The sharp selloff marked one of the index’s steepest single-day declines and underscored how quickly momentum can reverse after the benchmark’s recent run above the 5,000 level. The move matters because circuit breakers are designed to cool panic selling, and their activation signals stress across Korean equities that can spill into regional risk sentiment. Investors will watch whether the index stabilizes near the 5,000 threshold or extends losses when trading resumes, and whether authorities or regulators respond to the volatility.
