Thai baht weakened to 33.15 per USD at opening on 31 Aug 2026, down from Friday's close of 32.95. The weakness is driven by USD strength following Fed Chair Powell's signals of potential interest rate increases if inflation doesn't clearly decline toward the 2% target. CME FedWatch shows 57.5% odds of a 0.25%+ rate hike in September (up from 35%). Key monitoring points include Thai current account data, foreign fund flows, Middle East developments, and critical US economic indicators (employment, ISM/PMI, jobless claims). Foreign investors sold 12.2 billion baht in Thai equities during 24–28 Aug.
