South Korea’s KOSPI Triggers 20-Minute Halt After 8% Drop

South Korea’s KOSPI index fell 8% early in the session, triggering a circuit breaker that halted trading for 20 minutes. The decline accelerated near the start of trading, and the pause interrupted activity while the index was down sharply. The halt was the immediate market consequence of the KOSPI’s drop.

The 8% figure captures an early-session move, so the halt came before the day’s trading had played out. The circuit breaker converted a steep decline into a temporary interruption in market activity, making the pause a second concrete feature of the move alongside the percentage drop. The event pairs a sharp index loss with a defined 20-minute halt.

The selloff was not limited to South Korea. Japan’s Nikkei 225 fell 3.65% and moved below 59,000 in the same regional session. The two declines add a broader risk-off signal across East Asian equities, with the KOSPI halt marking the immediate market development.
