US Treasury reports Iranian crude loadings at zero barrels in August 2026 as Gulf exports shift to other producers

Treasury data and tracking from Kpler and Vortexa showed Iranian crude loadings fell from 250,000 barrels per day to zero in August. Goldman Sachs analysts recorded Persian Gulf exports recovering to 23.3 million barrels per day over the same period, with non-Iranian producers absorbing the volume previously moved by Tehran.

The shift followed expanded US naval presence and enforcement actions that constrained Iranian vessel movements while leaving other Gulf states' terminals unaffected. Iranian revenues from oil sales, previously estimated above $40 billion annually under prior sanctions regimes, face immediate interruption when loadings remain at zero.

Competing interests center on control of export capacity: the United States seeks to remove Iranian leverage over Strait traffic and reduce funding for regional proxies, while Iran has historically used oil flows to maintain fiscal stability and deter tighter blockades. Gulf producers gain market share but face longer-term pressure if US enforcement expands to secondary buyers.

Primary records consist of Bessent's Axios interview remarks, Goldman client notes on export divergence, and Bloomberg confirmation of August loadings data. Sustained zero loadings would require continued naval interdiction and buyer compliance with US secondary sanctions.
