Brent fell to $87.84 and WTI to $82.23 per barrel on 26 Aug 2026, the lowest since 10 Aug, after Iran and Oman discussed a temporary joint shipping route through the Strait of Hormuz. Kpler data shows only 5 cargo ships transited on the latest Tuesday, down from a 10-day average of 15 and still below pre-war levels, so supply remains tight. Ukraine's drone attack on Russia's NORSI refinery adds upside risk. For fuel and transport costs, expect prices to stay volatile; do not lock in cost assumptions on this dip alone.
