The won-dollar exchange rate against the U.S. dollar surpassed 1,550 won in overnight transaction on the 5th.
In Seoul's foreign exchange market overnight transaction that day, the won-dollar exchange rate stood at 1,555.5 won at about 10:30 p.m. The rate jumped to as high as 1,549.1 won at about 10:27 a.m. that day, then fluctuated in the 1,530–1,540 won range before ending regular transaction at 1,539.1 won. In the ensuing overnight transaction, it climbed sharply from around 9:30 p.m., crossing into the 1,550 won range.
This is the highest level in 17 years and 3 months since March 10, 2009 (intraday 1,561.0 won) during the global financial crisis.
With selling by foreign investors and the prolonged Middle East war increasing pressure on the won, a stronger dollar trend came to the fore, apparently contributing to the rate's rise. The U.S. May employment report released that evening showed unexpectedly strong labor conditions, pushing back expectations for a policy rate cut.
As a result, the dollar strengthened, and the dollar index, which shows the dollar's value against the currencies of six major countries, surged to the 99.6 level.
