The Singapore dollar weakened against the U.S. dollar during the Asian session as rising U.S. Treasury yields increased the appeal of dollar-denominated fixed-income assets. Higher yields in the U.S. bond market typically strengthen the U.S. dollar by attracting foreign capital seeking better returns, which puts downward pressure on other currencies like the Singapore dollar. This movement reflects broader market dynamics where shifts in U.S. monetary policy expectations influence currency valuations across Asia.

The Singapore dollar’s decline underscores its sensitivity to global interest rate trends, particularly those driven by U.S. economic data and Federal Reserve outlook.
