The KOSPI experienced a sharp rise in early trading, prompting the Korea Exchange to activate a buy sidecar in the stock market.
On June 12, at 9:06 a.m., the Korea Exchange announced that it had triggered the buy sidecar due to a significant increase in KOSPI 200 futures prices, which led to a five-minute suspension of program buy orders.
The price of the most actively traded KOSPI 200 futures contract rose more than 5% above the reference price of 1,236.05 points for over a minute, meeting the criteria for activation.
At 9:06:02 a.m., the futures price reached 1,332.00 points, an increase of 95.95 points (7.76%) from the reference price.
As a result, program buy orders were suspended for five minutes from the activation time and would automatically resume afterward. At 9:06 a.m., program trading recorded a net sell of 26.7 billion won.
The buy sidecar is a market stabilization mechanism designed to mitigate the impact of rapid price fluctuations in the futures market on the spot market. If the KOSPI 200 futures price rises or falls by more than 5% for over a minute, program buy orders are suspended for five minutes.
This marks the 25th activation of the buy sidecar this year. In 2026, the stock market has seen 13 buy sidecar activations and 12 sell sidecar activations. Since the current activation criteria were implemented in May 2001, there have been a total of 85 activations.
