Iran’s Oil Exports Collapse as Hormuz Standoff Drags On

More than six months after the U.S.-Iran war began, shipping traffic at the Strait of Hormuz remains disrupted, and oil prices are once again closing in on the $100 per barrel mark.The U.S. and Iran remain deadlocked at the start of the seventh month of the conflict. But the U.S. economic pressure on Iran has intensified, while oil flows out from the other Persian Gulf producers are estimated to have rebounded to about two-thirds of pre-war levels with mostly dark transits and shuttle-shipping for ship-to-ship (STS) transfers outside the Strait of Hormuz.The pressure on Iran from the U.S. Operation Economic Outcast and the U.S. blockade is stifling Tehran’s oil revenues and slashing the most important hard-cash income for the Iranian regime.As the economic pain on Iran intensifies, analysts have started to question how long Tehran would withstand the collapse of its most important revenue.Opinions diverge. Some say the economic pressure and pain on Iran has become so severe that Iran’s leverage of control over the Strait of Hormuz is cracking, especially as the economic pressure on Iran appears to be more intense than the pain on the global and U.S. economy it sought to inflict by closing the Strait of Hormuz.“The balance of power has tilted against Iran a bit,” Iranian analyst Arash Azizi told Reuters, noting that the U.S. blockade is hitting Iranian oil flows hard.Other analysts say that the hardliners and the Islamic Revolutionary Guard Corps (IRGC) continue to believe they have the leverage to cause economic pain and pressure the U.S. Administration two months ahead of the mid-term elections in November.Iranian Oil Exports CollapseThe U.S. blockade, reinstated in the middle of July after only three weeks of reprieve, is cutting off Iran’s oil exports and oil revenues.The volumes Iran managed to move through Hormuz during the three-week window in June and early July are rapidly dwindling from floating storage, while no Iranian vessel has managed to sneak past the blockade since the middle of July.Publicly, Iran remains defiant and claims it will find ways to dodge the U.S. blockade.But vessel-tracking services have estimated that Iran's oil exports plunged in August compared with a year earlier.Iran managed to load around 260,000 barrels per day (bpd) for export at its ports in August, an 80% slump compared to 1.7 million bpd loaded in August 2025, per data from trade intelligence firm Kpler cited by CNBC. The August loadings were also more than halved compared to about 740,000 bpd in July 2026.The loadings, however, do not mean that cargoes moved past the U.S. blockade. Various estimates put Iranian oil flows out of the Persian Gulf at zero last month.Kpler and other ship-tracking services, including Vortexa and TankerTrackers.com say the reinstated blockade has been very effective in crippling Iranian oil exports and oil revenues.TankerTrackers.com last week said that its estimates showed that Iran's oil exports plunged by 100% in August 2026 compared to the immediate pre-war baseline of January and February 2026.Economic Pain“This is the greatest economic isolation operation in the history of the world. We are going to asphyxiate this regime,” U.S. Treasury Secretary Scott Bessent told Fox News this weekend.The combination of the blockade and the U.S. sanctions is “one of the most powerful one-two punches in the history of economic isolation,” the official added.Despite the economic pain, Iran publicly remains defiant and vows retaliation for every U.S. strike. Many analysts doubt the regime will capitulate.“The Iranians have consistently surprised us in terms of their resiliency,” Dennis Ross, a former U.S. negotiator, told Reuters.Following the weekend U.S. attacks on Iranian tankers, Mohsen Rezaei, who led the IRGC during the 1980s Iran-Iraq War and is now the new secretary of the Supreme National Security Council, said “In recent days, Washington has received a clear warning from Iran’s new missiles. Economic warfare will be met by a maritime exclusion zone across the Persian Gulf to the blockade perimeter. The operational posture toward U.S. warships and bases has been fundamentally recalibrated.”There is little sign that Iran would yield to the intensified economic pressure, Gulf officials told the Wall Street Journal this week.Iran has also moved to provide more weapons and intelligence support to its allies, the Houthis in Yemen, who have targeted Saudi shipping in the Red Sea and the Bab el-Mandeb Strait, Saudi officials told the Journal.The economic consequences of the Hormuz disruption are also evident in the U.S. fuel prices—diesel just hit a record-high while gasoline prices at over $4 per gallon on average were the highest-ever for a Labor Day weekend in nominal terms. The U.S. Administration seeks to play down the price spike and the record fuel prices two months before the midterms, saying that it’s just temporary and worth the cause of never letting Iran have a nuclear weapon. After the U.S. wins the war, prices will plummet; this is Washington’s narrative.Iran is publicly defiant, but the economic pain is worsening as its oil revenues crash.“Now, much will depend on the degree of economic pain that the Iranian regime is willing to bear to achieve its military and geopolitical objectives,” Hamad Hussain, an economist at Capital Economics, told the Journal.By Tsvetana Paraskova for Oilprice.comMore Top Reads From Oilprice.comVitol CEO: Global Fuel Markets Are "Tight and Inflexible"Gulf Producers Find Workarounds As Hormuz Tensions PersistOil Tankers Flood Back Into Suez Canal As Red Sea Risk Grows
