Line chart of daily front-month Brent crude futures from August 17 to September 30, 2026, with offer and rejection markers.

Estimates of how much oil is moving through the Strait of Hormuz differ by more than four times depending on the source, which makes the actual supply loss hard to judge. Iran offered a seven-day reopening and Washington rejected the sequencing, yet Brent moved little on either headline. The Saudi East-West pipeline is running at about half capacity, and China has withdrawn some October fuel cargoes.
