The KOSPI index surged over 4% at the opening on news of a peace agreement between the United States and Iran. As expectations grow for reduced geopolitical risks in the Middle East, optimism is rising for the KOSPI to reach the 9,000-point mark after recently recovering above 8,400.
According to the Korea Exchange, as of 9:10 a.m., the KOSPI was trading at 8,489.37, up 365.75 points (4.50%) from the previous trading day. The index opened at 8,526.12, a rise of 402.50 points (4.95%), and has fluctuated around the 8,400 mark.
Due to the sharp rise in the KOSPI 200 futures index, a trading halt was triggered at 9:06 a.m. in the securities market, known as a buy-side circuit breaker. This marks the second consecutive day that a buy-side circuit breaker has been activated, following one on June 12. The buy-side circuit breaker is triggered when the KOSPI 200 futures price rises more than 5% compared to the previous day's closing price and remains above that level for over a minute.
Earlier, in the early hours of June 15, U.S. President Donald Trump announced the conclusion of peace negotiations with Iran via his social media platform, Truth Social.

The domestic stock market is reflecting this news with a bullish trend.
