KOSPI and KOSDAQ Trigger Level 1 Circuit Breakers Amid Plunge of Over 8%

As the domestic stock market plunged today (the 15th), both the KOSPI and KOSDAQ indexes plummeted by more than 8%, triggering consecutive circuit breakers.

According to the Korea Exchange, a circuit breaker was triggered for the KOSDAQ market at around 12:23:13 PM today, halting trading for 20 minutes.

At the time of the trigger, the KOSDAQ index stood at 757.88, down 66.00 points (8.01%) from the previous session.

Fifteen minutes later, a circuit breaker was also triggered in the KOSPI market.

At that time, the index was 5,528.05, down 480.76 points (8.00%) from the previous day.

The Korea Exchange triggers a "Level 1" circuit breaker when the KOSPI or KOSDAQ index drops by 8% or more from the previous day and remains at that level for one minute.

When a circuit breaker is triggered, trading is suspended for 20 minutes, and the acceptance of orders, excluding cancellation orders, is also halted.

Even after trading resumes, single-price trading is conducted for 10 minutes.

This is the first time in about two and a half months, since July 29, that Level 1 circuit breakers have been triggered on both markets on the same day.

Earlier in the morning session, sell sidecars had also been triggered sequentially in both the KOSPI and KOSDAQ markets.
