The baht opened at 33.45 per USD on 23 Sep 2026, down from 33.26 at the prior close. TTB expects a 33.30-33.60 range over 24 hours. Drivers: a stronger US dollar, falling gold below US$4,300/oz, rising US bond yields, and Brent crude above US$100/bbl. For importers paying in dollars, the weaker baht raises costs; for exporters, it helps margins. Check dollar-denominated supplier quotes and hedge if payments are due soon.
