Following a morning circuit breaker triggered by an over 8% drop in the KOSPI index, the Korea Exchange (KRX) experienced brief technical disruptions in order processing later Monday. Trading has normalized, with KRX investigating the issues amid concerns over system reliability during volatility.
On March 9, 2026, after the KOSPI benchmark plunged more than 8%—prompting a 20-minute circuit breaker halt earlier in the session—the Korea Exchange (KRX) faced additional technical glitches, delaying order processing from 12:30 p.m. to 12:33 p.m. and 1:39 p.m. to 1:41 p.m., per industry sources.
Local brokerage Mirae Asset Securities urged customers to check order executions due to potential delays from these system issues. A KRX official confirmed trading has resumed normally and said the exchange is probing the root cause.
This follows the sharp market drop detailed in prior coverage, highlighting persistent worries about KRX infrastructure handling extreme volatility, though no further details on fixes have emerged.
