A circuit breaker was triggered on the Kospi on Monday after geopolitical risks stemming from the Middle East battered the Korean stock market.

When a circuit breaker is activated, stock trading is suspended for 20 minutes.

The measure was activated after the index plunged 8.11 percent from the previous session to 5,132.07, despite a temporary trading curb known locally as a sidecar being triggered earlier the same day at 9:06 a.m.

A sidecar halts program trading for five minutes when certain market indexes fluctuate beyond a designated threshold.

At the same time, a sidecar was triggered on the Kosdaq market.
