Iran's Oil Exports Plummet Amid US Naval Blockade
Iran's oil sector is facing one of its most severe shocks in years due to a US naval blockade at the Strait of Hormuz. Vessel-tracking data shows that Iranian crude and condensate loadings averaged just 220,000 to 260,000 barrels per day in August 2026, compared to 1.7 to 2 million barrels per day a year earlier. This represents an over 80% collapse in export volumes.
The blockade, reinstated in mid-July 2026 after a brief easing, has had a devastating impact on Iran's oil exports. Since the blockade went back up, no confirmed Iranian crude cargoes have successfully passed the enforcement line.
Iran is drawing down its reserves to meet domestic needs and satisfy residual exports, but with nowhere to put new output, the National Iranian Oil Co. has been forced to dial back production. Analysts estimate that if the blockade holds, Iranian crude output could fall to 1.2 to 1.3 million barrels per day.
