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

As the domestic stock market plummeted today (15th), both the KOSPI and KOSDAQ indexes crashed by more than 8%, triggering successive 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 at 5,528.05, down 480.76 points (8.00%) from yesterday.

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 that situation persists 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 marks 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 the KOSPI and KOSDAQ markets.
