Iran’s crude loadings drop to one-seventh of pre-war levels as US blockade tightens

Iran’s oil export machine has been reduced to a trickle. Crude loadings from the country have fallen to roughly one-seventh of where they stood before the US-Israel conflict escalated in late February 2026, a collapse so severe it has effectively sidelined one of OPEC’s most important producers from global markets.

Pre-war, Iran was shipping between 1.5 and 1.85 million barrels per day. By May 2026, that figure had cratered to around 260,000 bpd.

The blockade’s grip

The mechanism behind the decline is straightforward: a US naval blockade of Iranian ports and the Strait of Hormuz, launched in tandem with the escalation that began on February 28, 2026. The chokepoint through which roughly a fifth of the world’s oil typically flows became, for Iranian tankers at least, a closed door.

An interim US-Iran deal in June briefly loosened the constraints, allowing loadings to recover to approximately 1.3 million barrels per day. That window didn’t last. A renewed blockade in mid-July slammed exports back down.

The financial toll has been enormous. Iran reportedly lost around $6 billion in oil revenues during the earlier blockade periods alone. That forced production cuts of approximately 1.2 million barrels per day, not because Iran chose austerity, but because there was simply nowhere for the crude to go.

China feels the squeeze

China has long been Iran’s lifeline in the oil market. Before the conflict, Chinese refiners were absorbing somewhere between 80% and 90% of Iranian exports, importing an average of roughly 1.4 million barrels per day.

Chinese imports of Iranian crude dropped to approximately 785,000 bpd in June 2026 and then fell further to around 534,000 bpd by August.

The drop in Chinese purchases has created a storage problem that’s approaching critical levels. Iran’s floating storage had climbed to around 105 million barrels before the renewed restrictions kicked in. That figure has since fallen to roughly 80 million barrels, and by mid-August only about 4 million barrels of Iranian crude were reportedly unsold and actively seeking buyers.

The decline in floating storage reflects not successful sales but reduced production. Iran isn’t selling more. It’s pumping less because there’s no market.

What this means for global oil markets

The removal of roughly 1.2 to 1.5 million barrels per day from global supply would normally send oil prices into a sharp rally. It hasn’t, at least not yet, and the reason is the other side of the equation: Chinese demand has been softer than expected, absorbing much of the supply disruption’s potential price impact.

Iranian barrels have been priced at steep discounts to international benchmarks for years, and their absence removes a source of cheap crude that Chinese independent refiners, known as teapots, had come to rely on. Those refiners now face either paying more for alternative supply or cutting throughput.

The interim deal in June showed that diplomatic channels aren’t entirely closed. But the speed with which restrictions were reimposed suggests that any future agreement would face the same fragility.
