Iranian crude and condensate loadings averaged just 220,000 to 260,000 barrels per day in August 2026, down from 1.7 to 2 million barrels per day a year earlier — an over 80% collapse tied to a reinstated US naval blockade of the Strait of Hormuz. Floating storage has fallen from about 90 million barrels in mid-July to roughly 29 million barrels by mid-September, and Iran's oil revenue is dropping by an estimated $200 to $250 million a day.
Vessel-tracking data shows Iranian crude and condensate loadings averaged just 220,000 to 260,000 barrels per day in August 2026, compared with 1.7 to 2 million barrels per day a year earlier. That marks an over 80% collapse in export volumes, measured in ships that actually moved oil rather than in a model.
The proximate cause is a US naval blockade at the Strait of Hormuz, reinstated in mid-July 2026 after a brief easing that followed a short-lived peace agreement in June. Since then, tracking reports show no confirmed Iranian crude oil cargoes have passed the enforcement line.
From storage glut to storage crisis
Floating storage — tankers sitting offshore loaded with unsellable crude — has dropped from roughly 90 million barrels in mid-July to about 29 million barrels as of mid-September 2026. Iran is drawing down those reserves to cover domestic needs and whatever residual exports it can still manage, not because new buyers have appeared.
With nowhere to put new output, the National Iranian Oil Co. has cut production. Analysts estimate that if the blockade holds, Iranian crude output could fall to 1.2 to 1.3 million barrels per day, a level closer to domestic consumption than to the country's historical export volumes. As a result, Iran is losing an estimated $200 to $250 million a day in oil revenue, compounding strain on an economy already dealing with high inflation and limited access to international financial systems.
China holds the remaining cards
Before the blockade tightened, China absorbed the overwhelming majority of Iranian oil exports, typically at discounted prices. That outlet is now largely closed — not because Chinese demand for cheap crude has fallen, but because the ships cannot get through. China can still draw down Iranian crude already sitting in its own storage, built up during months when exports flowed more freely.
Iranian Oil Minister Mohsen Paknejad and the National Iranian Oil Co. have publicly signaled defiance, but Iran's export leverage now depends heavily on what Beijing chooses to do with its existing stockpiles. By mid-September 2026, tracking data indicates Iranian exports have reached six-year lows.
What the cuts mean beyond Iran's borders
For refiners in Asia, particularly in China and India, Iranian crude had been a reliable source of cheap feedstock. The supply interruption forces procurement teams to look elsewhere, typically at higher prices — a cost that eventually passes downstream.
Iran's oil fields still need continuous investment and maintenance even at reduced output. Restarting wells shut in for extended periods carries technical and financial costs that compound over time.
