Reeling from 'War and Oil Price Shock'... KOSPI Closes Down 5.96%

'20-Minute Trading Halt' Circuit Breaker Triggered During Session
KOSDAQ Drops 4.54% as Sell-Sidecar is Activated

Amid the spread of Middle East-originated geopolitical risks, the Korean stock market closed with a sharp decline. During the session, both a sell-sidecar and a circuit breaker (20-minute trading halt) were triggered consecutively on the KOSPI, while a sell-sidecar was also activated on the KOSDAQ, amplifying market volatility.

On March 9, the KOSPI index closed at 5,251.87, down 333.00 points (5.96%) from the previous trading day. The index opened at 5,265.37, down 319.5 points (5.72%), and the decline continued to deepen throughout the session. Foreign investors sold a net 3.2049 trillion won, while institutions offloaded 1.5382 trillion won. In contrast, individual investors bought a net 4.6250 trillion won.

The Korea Exchange triggered a sell-sidecar on the KOSPI market at 9:06 a.m. that day. A sell-sidecar is activated when the KOSPI 200 futures index falls by 5% or more and stays at that level for a minute. Later, as the decline widened to over 8%, a KOSPI circuit breaker was triggered at around 10:31 a.m., suspending stock trading for 20 minutes.
