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
Qatar
Qatar
Qatar holds approximately $12 billion in frozen Iranian assets that Tehran named as the precondition for any Hormuz reopening sequence; with Oman sidelined and no agreed HEU custodian, the asset-routing architecture that any deal requires has no operational channel and no neutral financial intermediary to run it through.
Hengaw and Iranian civilian population
Hengaw and Iranian civilian population
Iranians face an internet capped at 40 per cent by hardware their president cannot dismantle, field killings that leave no court record, and judicial executions running in parallel; Hengaw, based in Norway, is the primary remaining monitor of a repression system the IRGC is deliberately moving beyond auditable records. The real toll is higher than any single monitor's count.
China
China
China supplied deep-packet-inspection hardware that caps Iran's internet at 40 per cent and enables an instant on-demand blackout, and was barred by Trump as a potential HEU custodian on 27 May. Beijing gains from Iran's continued non-alignment with the West while the DPI sale extends Chinese surveillance-technology exports as a geopolitical instrument.
Pakistan
Pakistan
Foreign Minister Ishaq Dar met Rubio in Washington on 29 May, formally inheriting the role of sole active mediator after Oman's forced withdrawal. Pakistan lacks Oman's banking infrastructure for frozen-asset routing and carries its own regional stakes, making it a less structurally neutral broker for the Qatar-held $12 billion sequencing.
Kuwait
Kuwait
Kuwait invoked Article 51 of the UN Charter after absorbing an Iranian ballistic-missile strike on Ali Al Salem Air Base on 28 May, becoming the first Gulf state to make a formal individual self-defence claim in the war. The invocation creates a legal record enabling a future bilateral defence-pact activation without yet triggering it.
Oman
Oman
Oman denied any Hormuz toll plan within hours of Bessent's 28 May threat, absorbing a sanctions warning from the country it has brokered for since 1981. The rapid capitulation preserved the channel formally, but Tehran now knows Washington will threaten its own mediator, which changes Muscat's calculus on how far it can lean into any joint-management architecture.
