Brussels cited UNCLOS transit rights to dismiss a US-Iran joint venture on strait fees.

Key takeaway

Europe sees Hormuz tolls as a threat to the entire maritime order, not a single waterway dispute.

The European Union rejected Donald Trump's suggestion of a US-Iran "joint venture" on Hormuz toll collection. Under UNCLOS (United Nations Convention on the Law of the Sea), which applies as customary international law to non-signatories including both Iran and the United States, ships enjoy transit passage that "shall not be impeded" and fees may only be charged for specific services rendered, not by reason of passage alone.

No post-1945 precedent exists for a coastal state imposing mandatory tolls on a natural international strait. Just Security assessed Iran's blanket selective toll as a "clear violation" of international norms. Iran's Islamabad proposal included a fee structure tied to vessel passage, as detailed in the Hormuz traffic event above.

Trump had previously called the toll concept "a beautiful thing." That language sits uncomfortably alongside the US's historical role as guarantor of freedom of navigation. The EU's rejection is a legal rebuke, but it has no operational teeth: Russia and China co-vetoed the UNSC Hormuz reopening resolution 11-2, blocking the only multilateral enforcement route for free navigation.

If tolls are formalised, the precedent extends far beyond Hormuz. Turkey could apply the same logic to the Bosphorus, Egypt could renegotiate Suez terms, Indonesia and Malaysia could toll the strait of Malacca. The EU's objection is not about Iran alone; it is about preventing the rewrite of a maritime order that underpins European trade.

Deep Analysis

In plain English

Trump suggested that the US and Iran could run a 'joint venture' together to collect fees from ships passing through the strait of Hormuz. He called the idea 'a beautiful thing'. The EU immediately rejected it. Under international law, countries cannot charge ships simply for passing through international straits. Ships have a right to pass freely. Fees are only allowed for specific services, like a pilot to navigate a difficult channel. Iran charging a blanket toll for permission to pass is, in the view of almost every international law scholar, illegal. The EU's rejection matters because European ships are among those currently stranded or blocked. But the EU has no military means to enforce its legal position in the strait, so the rejection is a principled statement rather than an operational one.

Deep Analysis
Root Causes

The EU's UNCLOS position reflects a genuine institutional commitment to rules-based maritime order that European states depend on for trade flows through multiple global chokepoints.

Trump's willingness to entertain a toll joint venture reflects a transactional approach to international law: rules are useful when they serve US interests and renegotiable when they do not. The US's own freedom-of-navigation programme, which has operated since the 1970s, was built on exactly the principle the Hormuz toll would undermine.

What could happen next?
  • Precedent

    Trump's positive framing of a US-Iran Hormuz toll joint venture, if pursued, would be the first US endorsement of a coastal state transit fee on a natural international strait, directly undermining the freedom-of-navigation doctrine the US has defended militarily for 70 years.

  • Consequence

    The transatlantic split on the Hormuz toll question, US treating it as potentially 'beautiful', EU rejecting it as UNCLOS-incompatible, reduces the coherence of any Western negotiating position and gives Iran leverage to play the two sides against each other.

Causes and effects
This Event
EU rejects Trump's Hormuz toll venture
The EU rejection exposes a transatlantic split: Trump entertained a toll concept that violates the maritime law framework Europe considers binding.
Different Perspectives
Russia
Russia
Russia vetoed the same renewal on 17 September, arguing that Britain, France and Germany never validly triggered the snapback that reimposed the pre-2015 UN resolutions. No panel was ever seated under that mandate, so the UN list decays fastest for states that screen against it rather than against the American one.
China
China
China vetoed renewal of the UN sanctions monitoring mandate on 17 September, arguing that Resolution 2231 terminated on 18 October 2025 and that the Security Council should drop Iran's nuclear file altogether. On that reading there is nothing to monitor, so the sanctions survive and their enforcement does not.
Iraq
Iraq
Baghdad saw the last American counter-Islamic State troops leave its territory on 30 September, completing a timetable it agreed with Washington in September 2024. Iraqi airspace deconfliction passes to Baghdad, which still has an open inquiry into the Maysan drone launches that has named nobody.
Pakistan
Pakistan
Treasury names Waseem Pasha Tajammal of Rawalpindi as the Cavalier group's chairman and places one of the designated incorporations in Islamabad. QatarEnergy separately told Pakistan that liquefied natural gas cargo cancellations would run through November, so Islamabad carries an enforcement question and a supply gap at once.
Turkey
Turkey
Treasury named a Cavalier Dynamics company incorporated in Istanbul among the ten nodes it designated on 29 September, and Ankara has published no response. Turkey imported a record 120,000 barrels a day of Indian diesel in August, cutting Russia's share of its diesel imports to 20 per cent.
India
India
Suraj Yadav, a wiper from Uttar Pradesh, was killed aboard the Cape Dao on 23 September, and 19 of the ship's 20 Indian crew were taken off alive. India's September imports ran at 575,000 barrels a day from Iraq and 566,000 from Saudi Arabia, back to pre-conflict rates.
