The Thai baht opened stronger at 33.13 baht per dollar on September 23 versus the previous close of 33.17. The strength reflects broader USD firmness driven by Federal Reserve policy signals supporting monetary tightening to combat inflation, with expectations of further rate hikes this year. Foreign investors sold net 796 million baht in Thai bonds and 3 billion baht in Thai equities. Geopolitical tensions in the Middle East and Trump's UNGA statements on Iran remain risk factors. Technical support at 33.00, resistance at 33.30 baht per dollar.
