Iran has run through the oil it had parked on tankers beyond the reach of the U.S. naval blockade, and by one tracker's estimate the money from its seaborne crude sales could stop arriving by the middle of December. Kpler, the energy intelligence firm, says Iran's trackable floating inventory outside the blockade zone has fallen to zero and projects that Tehran's crude revenue could dry up by mid-December as the last outstanding payments are settled, Fox News reported Sunday.
The lag comes from the way Iran gets paid. Buyers of its crude typically settle one to two months after delivery, according to the Fox report, so the cash trails the oil by weeks. When the war began in February, Iran had about 135 million barrels stored at sea; by Oct. 5 that had fallen below 1 million, according to Kpler figures reported by The Wall Street Journal and cited by Iran International. National Security Journal, relaying the same data, said Iran's floating reserves in Asian waters were empty by mid-October and that revenue from oil already shipped could reach zero by mid-December.
The trackers do not agree on exactly how close to empty Iran is. Vortexa estimated Iranian stocks off Singapore at roughly 6 million barrels on Oct. 9, a gap Iran International attributed to different tracking methods and locations. Both sets of numbers, it said, show that the offshore supply that kept Iranian exports going has largely been used up.
American officials have been putting numbers on the damage. Adm. Brad Cooper, the commander of U.S. Central Command, said on Oct. 16 that the blockade had kept at least $25 billion worth of Iranian crude from being exported and that U.S. forces had helped freeze about $350 million in cryptocurrency assets, Al Jazeera reported. "Iran has no exports or imports by sea," Cooper said, according to The Times of India. The dollar figure is the command's own estimate, and Iran International noted that it has not been independently verified as a measure of Tehran's net losses.
On Friday, Treasury Secretary Scott Bessent said in a post on X that Iran's shadow tanker fleet had been depleted, its main oil terminal emptied and its offshore reserves exhausted under Washington's economic pressure campaign, Iran International reported. He said ordinary Iranians kept suffering because their government spent its resources on violence and terrorism abroad. "As President Trump takes action that his predecessors long deferred, the United States is no longer managing the Iranian threat. We are ending it," he wrote.
Oil directly covers roughly 30% of Iran's government budget, according to Gregory Brew, a senior Iran and energy analyst at Eurasia Group, and Miad Maleki, an Iran sanctions specialist at the Foundation for Defense of Democracies, both of whom spoke to Fox News. Maleki estimated that oil and refined products make up 50% to 60% of the regime's revenue once indirect income is counted. Brew said Iran entered the year planning to export about 1.7 million barrels a day at around $54 a barrel; it fell short of that, though higher prices let Tehran build some cushion.
That does not mean Iran simply runs out of money in December. "The December timeline is more of a cash flow kind of disruption, and not really a collapse state," Maleki said. Tehran has so far let inflation and a weakening rial absorb some of the strain instead of halting government salaries or allowing widespread shortages, and the pain could fall harder on ordinary Iranians than on the military. Brew said there is a broad expectation that nonmilitary spending will be cut sharply while military spending holds steady or even rises because of the country's war footing. Iran is already paying to rebuild missile production sites and repair damage to its nuclear program, he said.
The armed forces also have their own claim on the oil. The Treasury Department said last year that Tehran was setting aside roughly 200,000 barrels of crude a day for the military, with the planned allocations worth more than $10 billion a year, and military bodies can sell that oil abroad and keep the money. The Islamic Revolutionary Guard Corps also earns from smuggling and sanctions-evasion networks that sit outside the formal budget. Brew said there is a world in which the Guard benefits from the new environment rather than being squeezed like the rest of the budget.
Iranian officials reject the idea that the economy is collapsing. "Despite all these pressures, the Iranian economy has demonstrated very good resilience, and the claim that Iran's economy is collapsing is nothing more than an illusion," Central Bank chief Abdolnaser Hemmati said earlier this month, Al Jazeera reported. President Masoud Pezeshkian acknowledged on Oct. 18 that military attacks and the maritime blockade had created substantial problems, but he said his government was relying on domestic capacity to withstand the pressure. The World Bank projected this month that Iran's economy will shrink 7.7% in the 2026-27 fiscal year.
Some Iranian oil will keep moving. Smaller volumes can travel overland by truck and rail or across the Caspian Sea, and refined fuels and petrochemicals can use routes outside the seaborne crude trade the blockade targets, Fox reported. "While the amount of Iranian oil that can be tracked has fallen to zero, it's unlikely Iran's oil exports completely fall to nothing," Brew said. The sanctions-evasion network itself is intact, Iran International observed: Tehran still has the middlemen and shadow-fleet machinery it spent years building, but ship-to-ship transfers and false paperwork cannot get fresh cargoes out of Iranian ports.
Both analysts said a deal with Washington that let Iranian tankers leave the Persian Gulf again could reverse the slide. Without one, the pressure is expected to build into next year, and the harder test may come in March, when Iran starts a new fiscal year and has to square its spending plans with far less oil income. "There's going to be a fiscal squeeze, and there's going to be pressure around the release of the new budget," Brew said.
