The Trump administration’s blockade of Iranian shipping is squeezing the country’s oil trade hard, cutting exports by three-quarters since April 13 and forcing Iran to hunt for places to store crude it can no longer move.
Iran is still loading and exporting oil, but the pressure is building fast as storage space tightens and the stakes rise for a system built around selling crude abroad. Donald Trump said over the weekend that Iran’s coming oil shutdown would make its oil lines explode, adding that “when it explodes … you can never rebuild it the way it was.”
Tuesday’s jump in oil prices showed how much the market is already reacting. U.S. oil rose to over $100 a barrel, and the global benchmark topped $111 a barrel, underscoring how quickly the blockade has become a wider energy problem, not just an Iran problem.
The strategy behind the U.S. blockade is blunt: force Iran to shut down oil wells once it runs out of storage for crude it can no longer ship. That would be a painful test, but Iran has lived through severe sanctions pressure before under both the Obama and Trump administrations, and earlier production shutdowns did not leave lasting damage to its oil fields.
That history matters because the current squeeze is real, but it is not yet a clean shutdown. Iran is still moving oil, even as its exports fall and storage fills. U.S. Gulf allies are already in month two of their own production shutdowns, and those cuts are larger collectively than anything Iran is likely to face. Scott Bessent said a production shutdown would trigger domestic gasoline shortages in Iran, a reminder that the pressure is meant to hit consumers as much as producers.
What happens next depends on whether Iran can keep finding room for its crude and keep enough of its oil system running to avoid the kind of shutdown Washington is trying to impose. The battle over storage, not just wells, is now the part of the story that will decide how far the squeeze goes.
