The won-dollar exchange rate fell slightly on June 15, driven by news of a ceasefire between the United States and Iran and net buying by foreign investors.

In the Seoul foreign exchange market, the won-dollar exchange rate closed at 1,511.1 won, down 8.7 won from the previous trading day (based on the 3:30 p.m. closing time).

This marks the lowest closing level for daytime trading since June 1 (1,504.3 won).

The exchange rate opened at 1,511.4 won, down 8.4 won, and fell to as low as 1,503.9 won during intraday trading at 9:26 a.m., before showing a slight upward trend thereafter.

The intraday high for the day was 1,513.8 won.

It is the first time since June 1 (when the high was 1,518.2 won) that the intraday high has dropped into the 1,510-won range.

The exchange rate has been on a downward trend due to the influx of risk-on sentiment following the U.S.-Iran ceasefire agreement and net buying of stocks by foreign investors.

U.S. President Donald Trump posted on the social media platform Truth Social at approximately 5:30 p.m. Eastern Time on June 14, stating, "The agreement with the Islamic Republic of Iran has now been finalized."

It is reported that the U.S. and Iran are set to sign a Memorandum of Understanding (MOU) on the ceasefire, which includes the reopening of the Strait of Hormuz, on June 19 local time.

This effectively brings an end to the war between the U.S.-Israel and Iran after 106 days.

In the KOSPI market, the index closed at 8,545.98, up 5.20% from the previous trading day.

Foreign investors, who returned to net buying on June 12 for the first time in 25 trading days, purchased 982.4 billion won worth of stocks today.

As of 3:30 p.m., the dollar index, which measures the value of the dollar against six major currencies, was at 99.525, down 0.282 from the reference price at the same time the previous day.

The won-yen cross rate stood at 943.70 won per 100 yen, down 4.63 won from the reference price at the same time the previous trading day (948.33 won).

The yen-dollar exchange rate fell 0.122 yen to 160.146.
