Gulf Oil Flows Near Pre-War Levels, but Iran’s Leverage Over Hormuz Erodes

Core Event: Near-Pre-War Export Volumes and Route Reconfiguration
In September 2026, crude leaving the Persian Gulf reached at least 16.5 million barrels per day (mbd), matching the pre-war average when Iran is excluded, according to commodity-analytics firm Kpler. JPMorgan estimated daily flows at 17.5 mbd, while Goldman Sachs projected 19 mbd. Oilprice reported a broader figure of 23.3 mbd that includes “dark” exports. The recovery occurs despite a U.S. naval blockade that has kept Iran’s own shipments near zero.
Background & Context
The war that began in late February 2026 closed the Strait of Hormuz, Iran’s historic chokepoint for roughly 20 percent of global oil trade. The blockade forced Gulf producers to develop alternative pipelines, Red-Sea routes, and offshore ship-to-ship (STS) transfers. By early October, 40 percent of Gulf crude bypassed Hormuz, up from 17 percent before the conflict, with Saudi Arabia’s East-West pipeline and the UAE’s Abu Dhabi-Fujairah link handling much of the rerouted volume.
Data & Statistics
- Export volumes: Kpler 16.5 mbd (Sept 1-28); JPMorgan 17.5 mbd; Goldman Sachs 19 mbd; Oilprice 23.3 mbd (including dark exports).
- Route shift: ? 40 % of crude now avoids Hormuz; ? 60 % (9.9 mbd) still crosses the strait, with > 70 % of that cargo transferred offshore in the Gulf of Oman.
- STS activity: Vortexa recorded 2.5 mbd in September, up from 1.4 mbd in August, representing ? 40 % of oil moving through Hormuz.
- Cost impact: Charter rates for VLCCs surged from $30-50 k to over $1 million per voyage; insurance premiums rose to 10 % of cargo value for high-risk passages.
- Security incidents: UKMTO reported at least seven tankers struck between late September and early October, including attacks on September 12.
Official Statements & Responses
- Iranian leadership: Parliament speaker Mohammad Bagher Ghalibaf, quoted by Nour News, said the strait will remain closed until Iran’s seven conditions from the Islamabad Memorandum are met, including an end to U.S. “acts of aggression” and the release of Iranian assets.
- Regional actors: Iraqi Oil Tankers Company director Ali Qais confirmed a pilot shipment of 2 million barrels through the strait, marking the first such transit in decades.
Criticism & Opposition
Think-tank founder Esfandyar Batmanghelidj warned that Iran could resort to a “scorched-earth campaign” if pressure persists. Energy-market analyst Rory Johnston described the current transport system as “impressive … never sustainable” because of its high cost.
On-the-Ground Reports
A veteran tanker captain, speaking to Bloomberg, described evasive navigation—no lights, disabled AIS, sandbagged decks—and real-time coordination with U.S. Navy aircraft while crossing Hormuz. He recounted a near-miss when a projectile struck a nearby vessel, prompting the captain to steer his 300-meter ship around the blast. UKMTO alerts confirmed multiple projectile-related incidents near Oman and within the strait during the same period.
Conflicting Reports & Gaps
Export estimates vary: JPMorgan (17.5 mbd) and Goldman Sachs (19 mbd) differ from Kpler’s 16.5 mbd and Oilprice’s 23.3 mbd figure that includes untracked “dark” shipments. Refined-product flows remain poorly documented; while crude volumes have rebounded, diesel and gasoline shipments are still ? 40 % below pre-war levels, according to industry sources.
What’s Next
A U.S. carrier strike group is slated to arrive in the region, according to Oilprice. The technical outlook for crude futures is set to be evaluated on October 9 (scheduled) as traders react to the “war premium” embedded in current prices.
