Iran Plans to Charge Transit Fees for Strait of Hormuz Passage, Modeled After Turkey's Approach
Nashnova编辑部
Iran's parliament is advancing legislation to levy service fees on ships transiting the Strait of Hormuz — a chokepoint carrying roughly a fifth of the world's crude — a move that, if enforceable, would reshape both shipping costs and the geopolitical bargaining landscape.
What exactly does Iran want to charge for?
Iran's parliamentary National Security and Foreign Policy Committee has drafted a bill covering navigation safety monitoring, rescue operations, and fuel supply services.
Iranian officials estimate the fees could generate roughly $40 billion a year for the countries involved.
This means → Iran is trying to reclassify the Strait of Hormuz from a free public waterway into a paid service zone, monetizing geography directly.
Why copy Turkey's playbook?
Turkey charges ships transiting the Bosphorus and Dardanelles for lighthouse operations, maritime rescue, and quarantine services.
After roughly 40 years with no adjustment, Turkey first raised fees in 2022 and has hiked them about 15% annually since; the rate hit $6.70 per net ton this July, up from $0.80 four years ago — roughly an eightfold increase.
In the fiscal year through June, Turkey's service fees totaled $259 million.
In plain terms = Turkey proved that repackaging a "transit toll" as a "service fee" can win international acceptance — and once the door opens, prices can climb year after year. Iran wants to replicate that path.
Where does international law draw the line?
The UN Convention on the Law of the Sea explicitly bans states from charging ships solely for transiting international straits — which is precisely why Iran frames its plan as a "service fee" rather than a "transit toll."
Former Turkish diplomat Mithat Rende, an ex-chair of the OECD Executive Committee, stated: no country can levy charges on maritime transit without approval from the UN's International Maritime Organization.
This means → even if Iran passes the bill domestically, it faces steep international opposition; between legislation and actual revenue stands a wall of international law.
Why does this matter beyond the legal debate?
The Strait of Hormuz is one of the world's most critical crude-oil shipping lanes; whether Iran can turn legislation into an enforceable fee mechanism is the single biggest uncertainty.
This reflects a deeper signal: countries that control resource chokepoints are collectively testing how far they can monetize geography — Turkey has already succeeded, and Iran is following.
In plain terms = whether or not Iran ever collects a dollar, the legislative push alone adds a layer of geopolitical risk premium to global oil-shipping costs.
