SEOUL. South Korea's KOSPI index fell 9.6% in a session where circuit breakers were triggered and losses accelerated once trading resumed, according to market data.

The halt and what came after

The KOSPI sold off to a level that triggered circuit breakers, pausing trading on the exchange. The mechanism exists to halt market activity when an index falls past a predetermined threshold, creating an interval before participants can resume buying or selling. When the KOSPI reopened, the decline did not reverse. Losses widened after the pause, bringing the index's total drop to 9.6%.

What the data records

Market data showed intensifying losses following the circuit-breaker resumption. The 9.6% figure covers the full session decline, including the initial move that triggered the halt and the selling that continued after trading came back. A triggered halt followed by resumed and deepening losses reflects conditions where the automatic pause did not relieve pressure on the index.
