On 8 Oct 2026 West Texas crude rose to US$91.49/bbl (+3.21) and Brent to US$104.28/bbl (+4.08). Drivers: US-Iran tension, with reports the White House is discussing renewed military action in coming weeks, and at least 12 attacks on tankers near the Strait of Hormuz between 28 Sep and 5 Oct. Hurricane Idalia also shut about 62.9% of US Gulf of Mexico oil output. Prices eased slightly after Trump said talks continue and no strike before the 3 Nov midterms; Iran is considering a US reply on reopening Hormuz within seven days. For a Thai SME, expect diesel and transport costs to stay volatile: review fuel surcharges in quotes, and avoid locking in long fixed-price fuel or freight contracts until the Hormuz outcome is clearer.
