The baht opened at 33.41 per US dollar on 4 Aug, roughly flat from 33.43 the previous close. TTB expects a 24-hour range of 33.25–33.65. The move follows a joint Japan–US yen-buying intervention last week, and traders are watching US jobs data this week for Fed signals. US manufacturing PMI rose to 55.6 in July, the highest since May 2022. Foreign investors sold a net 1,619 million baht of Thai equities and 165 million baht of Thai bonds on Monday. For importers and exporters, this is a small daily move; check your USD payment and quote assumptions against this range, but no change to plans is needed from one day's data.
