The USD/KRW exchange rate rose from the 1,400-won range during the London session. The local currency was trading at 1,404.20 won against the U.S. dollar as of 7:20 p.m. on Tuesday, above 10.00 won from the previous session. USD/KRW opened at 1,396.00 won against the U.S. dollar and closed at 1,401.30 won as of 3:30 p.m. Since then, the local currency has traded in the 1,400-won range in earnest. Entering the London session, the dollar rose to its peak at 1,404.50 won. The dollar rose sharply as demand for settlement flowed in along with the strong global dollar. However, USD/KRW was limited as trading slowed due to concerns over authorities' intervention around the 1,405 won level. "The dollar rose technically due to the dollar index's rising," a foreign exchange dealer at a commercial bank said. "Until last week, we continued to be wary of intervention ahead of the 2 a.m. closing price," he said. "We continued to be wary of intervention in night trading." The dollar index has been on the rise around 106.38. At the same time, the dollar-yen exchange rate rose 0.57 yen to 150.33 yen, while the EUR/USD fell 0.0006 dollars to 1.051dollars.
