The won-dollar exchange rate closed at 1,489.3 won on the 13th against the U.S. dollar. It rose 6.8 won from the previous transaction day.
This is seen as the result of the collapse of end-of-war talks between the United States and Iran. If so, investor sentiment in the market toward risk assets tends to weaken, and the value of the won, which is not a reserve currency, tends to fall.
U.S. Vice President JD Vance, who led the U.S. delegation, said at a press conference at the Serena Hotel in Islamabad, Pakistan, on the 12th local time, "We did not reach an agreement with Iran and will return to the United States without an agreement." They negotiated with Iran for 21 hours but did not reach a deal. Vice President Vance said Iran did not accept the U.S. demands. Vance said, "We need an explicit promise that they will not pursue nuclear weapons and will not pursue the means that would allow them to acquire nuclear weapons quickly."
Afterward, U.S. Central Command, which oversees the Middle East, said starting at 11 p.m. on the 13th Korea time, it would blockade all maritime traffic entering and leaving Iranian ports. On X (formerly Twitter), it said, "This blockade measure will apply fairly to ships of all countries entering and leaving Iranian ports and coastal areas, including all Iranian ports located in the Persian Gulf and the Gulf of Oman." As Iran tried to pressure the United States by threatening to blockade the Strait of Hormuz, this appears to be a countermove.
On the same day, U.S. President Donald Trump said international oil prices may not fall until fall. In an interview with Fox News, when asked, "Will oil and gasoline prices fall by fall?" Trump said, "They could, they could be the same, and they might be a little higher. But generally they'll be about the same level."
