The Korea Exchange announced on the 12th that it activated a 'Buy Sidecar' at the KOSPI market, temporarily suspending the validity of program buy orders for five minutes. According to the exchange, the sidecar was activated at 9:06:02 a.m. on June 12, 2026. The measure was taken after the price of the futures contract based on the KOSPI 200, which had the highest trading volume on the previous trading day, surged. The futures price reached 1,332.00 points, surging by 95.95 points (7.76%) compared to the base price of 1,236.05 points. The exchange explained that as the futures price maintained an increase of over 5% for more than a minute, it suspended the validity of program buy orders in the KOSPI market for the next five minutes. The sidecar is a market stabilization mechanism introduced to mitigate the impact of rapid price fluctuations in the futures market on the spot market. When certain criteria are met, it suspends the validity of program trading orders for five minutes to prevent excessive bias toward buying or selling. This measure was implemented in accordance with Article 16 of the Securities Market Business Regulations.
