The South Korean won falls against the U.S. dollar on Tuesday, driven by renewed market expectations that the U.S. Federal Reserve could raise interest rates later this year. The won opens around 1,539.4 won per dollar and trades lower during the session, reaching about 1,540.1 won per dollar at its weakest point, the lowest level since June 8. By late afternoon, it is quoted near 1,539.1 won per dollar, down roughly 2 won from the previous session. The movement follows the Fed’s decision last week to hold its benchmark rate steady, its first rate review since new Chair Kevin Warsh took office, while at least half of policymakers reportedly anticipate a higher rate later this year. The won also weakens as traders expect a stronger U.S. dollar. While global oil prices decline amid progress in U.S.-Iran peace talks, Korean assets remain under pressure, with Korean stocks opening lower and the benchmark Korea Composite Stock Price Index falling nearly 10 percent to close at 8,203.84. Foreign investors sell a net 4.1 trillion won of local shares on Tuesday.
