The South Korean won fell to around 1,412 per dollar on Tuesday, extending losses for a fourth straight session and hovering near a five-month low, as the dollar strengthened amid stalled US funding talks and persistent global uncertainty. The greenback gained after competing budget proposals failed to advance in the Senate, prolonging the week-long US government shutdown. Investors also looked ahead to comments from Federal Reserve officials later this week for further policy cues. At the same time, weakness in regional currencies, particularly the yen, added to downside pressure on the won amid broader dollar demand, as Japan’s leadership transition fueled expectations of continued fiscal stimulus. Meanwhile, with South Korean markets closed for a local holiday, onshore trading remained muted.
