On 3 Aug 2026 Brent fell to US$83.77 a barrel (down $6.35) and West Texas Intermediate to $80.34 (down $4.33) after Trump signalled a pause in strikes on Iran and talks. Iran's foreign ministry spokesperson said no talks are planned, so the drop may reverse. Tankers from Saudi Arabia are rerouting around the Gulf of Aden because of Houthi threats. For a Thai SME, expect fuel and diesel prices to move with crude, so keep a buffer in transport and energy budgets and avoid locking in cost assumptions based on this single-day drop.
