The baht opened at 33.60 per dollar, slightly weaker than the previous close of 33.58, with a 24-hour range of 33.40-33.70. Markets expect the US Federal Reserve may hike rates in December (90% weight per CME FedWatch), which is pushing the dollar up. For importers paying in dollars, costs may edge up; exporters may gain slightly. Foreign investors sold a net 2,136 million baht of Thai stocks the previous day.
