Iran Seeks Billion-Dollar Toll for Vital Strait, Threatening Global Trade

Iran Seeks Billion-Dollar Toll for Vital Strait, Threatening Global Trade

By Paul V. Young – TheNATIONWEEK.com | March 30, 2026

TEHRAN – Iran has introduced a significant new demand to end the ongoing conflict, aiming to formalize control over the strategically critical Strait of Hormuz and potentially generate billions in annual revenue. 

This unprecedented move signals a shift in Tehran’s leverage strategy, transforming the narrow waterway – through which a fifth of the world’s oil and liquefied natural gas (LNG) ordinarily passes – into both a financial asset and a potent geopolitical pressure point.

An Iranian official recently articulated this demand, seeking international recognition of Iran’s sovereignty over the Strait of Hormuz. This ambition extends beyond past threats of closure in case of an attack, now suggesting a move towards a permanent tolling system.

The Economic Weaponization of Hormuz

Shipping through the chokepoint has significantly diminished due to Iranian attacks, disrupting global energy markets and compelling nations worldwide to implement emergency fuel security measures. 

Experts suggest Iran’s “comparatively easy and cheap” success in holding the global economy hostage has emboldened its long-term ambitions.

“Iran has been a little taken aback by how successful its (Hormuz) strategy has been,” states Dina Esfandiary, Middle East lead at Bloomberg Economics. “One of the lessons learned in the war is that it has discovered this new leverage, and it’s likely to use it again in the future. And I think monetizing it is part of discovering that it has this leverage.”

International Condemnation and Legal Challenges

Washington has swiftly reacted to this development. U.S. Secretary of State Marco Rubio warned against Tehran’s attempts to establish a tolling system, labeling it “illegal, unacceptable, and dangerous to the world.” G7 foreign ministers have unanimously stressed the “absolute necessity” of restoring “safe and toll-free freedom of navigation.”

The legal basis for such tolls is highly contested. James Kraska, a professor of international maritime law, asserts that “imposing transit fees is a violation of the rules of transit passage” under international law. 

While Iran is not a party to the UN Convention on the Law of the Sea (UNCLOS), many of its core principles are widely accepted as customary international law, challenging Iran’s potential claims. 

Historical precedent also weighs against Iran, with Denmark’s 19th-century attempts to impose transit fees through the Danish Straits ultimately abolished by the Copenhagen Convention of 1857.

A Lucrative Prospect for Tehran

Despite legal obstacles, Iran is actively exploring the feasibility and profitability of a tolling system. Experts estimate that if successful, revenues could rival those of Egypt’s Suez Canal. 

With approximately 20 million barrels of crude oil and oil products transiting daily, at a reported fee of $2 million per very large crude carrier (VLCC), oil tolls alone could generate around $600 million monthly. Including LNG shipments, this figure could exceed $800 million per month, representing a significant portion of Iran’s current monthly oil export revenue.

This monetization strategy is likely driven by Iran’s severe economic pressures and extensive international sanctions, making it an “easy” and “low-cost” mechanism to offset financial shortfalls.

Testing the Waters: Covert Payments and Controlled Passage

While Iran officially maintains the Strait of Hormuz is open for “non-hostile” vessels coordinating with Iranian authorities, evidence suggests Tehran is already testing a controlled passage system. 

Ship-tracking data indicates some tankers are using routes closer to Iran’s coast, with reports of operators potentially paying for safe passage.

Lloyd’s List, a shipping intelligence firm, reported that over 20 vessels have utilized a “new corridor” through the strait, with at least two ships understood to have paid for passage, one reportedly around $2 million. 

Furthermore, Iran’s Islamic Revolutionary Guard Corps has reportedly established a registration system for approved vessels, and some governments are engaging directly with Tehran to secure transit for their tankers.

The shipping industry faces growing uncertainty and “paralysis” as this unofficial system unfolds, underscoring the immediate and evolving challenges posed by Iran’s new demands. 

The international community now faces the critical task of confronting this unprecedented move and safeguarding the freedom of navigation through one of the world’s most vital maritime arteries.
