The Korea Exchange activated a sell-side program trading circuit breaker (sidecar) in the KOSPI market at 11:23 AM on the 24th, as the index plunged amid rising oil prices and geopolitical tensions. The trigger came after KOSPI opened down 96.11 points (1.35%) at 7000.78, with KOSPI 200 futures falling 5.04% to 1070.80 when the mechanism engaged. This marked the 21st sell sidecar activation for KOSPI this year and the 41st total including buy sidecars, continuing a pattern where circuit breakers have triggered every trading day this week. The sharp decline followed overnight weakness in US stocks and escalating Middle East geopolitical risks that drove international oil prices higher. Han Ji-young, a researcher at Kiwoom Securities, noted that geopolitical uncertainty between the US and Iran, combined with the US market drop, pressured Korean stocks, while surging oil prices created renewed interest rate concerns that could increase valuation discount pressure in equity markets.

KOSPI 200 Futures Drop 5.04% When Sidecar Engages

Kiwoom Securities Cites Geopolitical Risks and Oil Price Pressure
Han Ji-young, a researcher at Kiwoom Securities, stated that domestic stocks opened lower due to expanded US-Iran geopolitical uncertainty and the fallout from the sharp US market decline. Han explained that surging oil prices are creating renewed upward pressure on interest rates, which could generate valuation discount rate burdens in the stock market.
