KOSPI and KOSDAQ Drop Over 8% Triggering Second Consecutive Circuit Breaker

South Korean exchanges halt trading as indices plunge >8%, marking the second day of circuit breaker activation amid severe market turbulence and broad-based selling pressure.

Woofun AI reports that the Korea Exchange activated its circuit breaker mechanism for a second consecutive day after the KOSPI and KOSDAQ indices each declined by more than 8%. Trading was suspended for approximately 20 minutes to stabilize markets, with further halts possible at 15% and 20% declines. The simultaneous drop in both indices indicates broad-based selling pressure rather than sector-specific weakness, driven by global macroeconomic headwinds including rising interest rates and geopolitical tensions.
