Iran's Oil Exports Plummet Under US Naval Blockade

The US naval blockade imposed on Iran has significantly reduced the country's oil exports. According to vessel-tracking data, Iranian crude loadings averaged around 220,000 to 260,000 barrels per day in August 2026, a collapse of more than 80% from the approximately 1.85 million bpd exported earlier in the year.

The blockade, reimposed on July 14, has effectively sealed the waters south of the Strait of Hormuz to Iranian tanker traffic. No confirmed crude shipments have made it past the enforcement line since mid-July.

Tehran has maintained that it can still export crude, but independent tracking data suggests otherwise. Iran's primary workaround has been tapping pre-blockade floating storage, selling oil already loaded onto tankers before the enforcement line went up. However, this is a finite strategy, and once these inventories drain, production cuts become unavoidable.
