Iran Oil Exports Face Zero Revenue Risk After Blockade

Iran could lose its main source of foreign currency as a blockade halts crude and condensate shipments, with analysts warning on October 11, 2026, that remaining oil cargoes may only provide income until December, according to Iran International.

Kpler data cited by Iran International showed Iran loaded no crude oil or condensate onto tankers during September, the first full month without loadings since the 1979 Islamic Revolution. The last recorded loading occurred around August 26 or 27.

Analyst Homayoun Falakshahi of Kpler told Iran International's Eye for Iran that Tehran's oil revenue could fall sharply as the blockade limits exports and remaining shipments approach delivery.

"Revenues from crude and condensate will drop to zero for the first time ever," said Homayoun Falakshahi, analyst at Kpler.

Falakshahi said about eight million barrels of Iranian crude remained at sea outside the blockade, down from nearly 90 million barrels in mid-July. He estimated the remaining shipments would be discharged around October 18.

"This is a first in history," said Homayoun Falakshahi, analyst at Kpler.

Iranian oil exports have continued through previous crises, including the 1979 revolution, the Iran-Iraq war and Western sanctions, although volumes declined during periods such as the COVID-19 pandemic, according to Falakshahi.

Falakshahi said sanctions-evasion methods would face greater challenges because the current restrictions affect physical tanker movements rather than only financial transactions.

"You'd probably see videos of it on the internet," said Homayoun Falakshahi, analyst at Kpler.

Falakshahi was referring to the difficulty of moving large quantities of oil by truck through alternative routes. He estimated transporting enough crude to fill a large tanker would take around 20 days.

The analyst said rail and overland options would not replace previous sea export volumes. He added that Turkmenistan was reportedly restricting rail transit because of concerns over US sanctions.

"Iran has a history of evading sanctions successfully to an extent," said Homayoun Falakshahi, analyst at Kpler.

Falakshahi said Iran's previous methods of maintaining exports would be harder to use under a physical blockade. He described the current situation as a more difficult challenge for Tehran.

"But this seems a lot more challenging," said Homayoun Falakshahi, analyst at Kpler.

The pressure also affects imports, with Falakshahi saying shipments of agricultural products such as corn and wheat have declined while alternative routes through the Caspian Sea have limited capacity.
