WTI crude prices have fluctuated between roughly $90 and $100 per barrel in September 2026 amid persistent Middle East supply risks and shifting geopolitical signals. The US-Iran conflict has kept several million barrels per day of Gulf exports constrained, supporting a risk premium even as Saudi East-West pipeline flows resume and Strait of Hormuz transits rise. Recent EIA data showed a larger-than-expected 2.97 million barrel US inventory build, while OPEC+ held October output targets steady after completing its earlier quota unwind. Trader positioning reflects these crosscurrents, with prices sensitive to any further diplomatic progress on Hormuz access versus renewed attacks on regional infrastructure. Upcoming weekly inventory releases and central bank commentary on energy-driven inflation remain key near-term inputs.
