FX.co ★ Thai Baht Slides to 1-Year Low

The Thai baht weakened beyond 33 per US dollar in late June, its softest level since May 2025, as widening interest rate differentials between the United States and Thailand weighed on the currency. Markets are now pricing in the possibility of further tightening by the Federal Reserve by October, while expectations for Thai interest rates imply less than a 50% probability of any policy move over the next six months. This divergence is reinforcing yield differentials that continue to pressure the baht.

The Bank of Thailand is widely expected to leave its policy rate unchanged at 1% this week, maintaining an accommodative stance to support economic growth. At the same time, Thailand’s macroeconomic backdrop remains fragile, with elevated household debt, subdued consumption, and external headwinds restraining momentum. Slower demand from China and intensifying global competition are also weighing on the outlook, while structural challenges—including a shrinking workforce and softer tourism flows—add further pressure.
