The South Korean won strengthens against the U.S. dollar as multiple factors align, including the U.S. Federal Reserve’s decision to hold interest rates steady and domestic flows that improve dollar availability. On Thursday, the won rises to a fresh five-month high, quoted at 1,437.4 won per dollar at 3:30 p.m., after the Fed leaves its benchmark rate unchanged in the 3.5% to 3.75% range. Although the Fed’s pause marks its fifth consecutive hold, three policymakers dissent and call for a rate hike, which keeps some expectations of future tightening in focus.
Earlier in the month, the won also records its strongest monthly performance since March 2009, gaining about 125 won in July. Analysts attribute the rebound to an improving dollar supply, including exporters stepping up dollar sales and SK hynix converting proceeds from a Nasdaq ADR offering into won. Additional support comes from foreign investors’ net purchases of South Korean stocks, which coincides with large jumps in the Korea Composite Stock Price Index.
Some outlets also note market-smoothing or coordinated FX intervention speculation, pointing to simultaneous yen strength and won gains.
