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
Human rights monitors (Hengaw, Amnesty International, Iran HRM)
Human rights monitors (Hengaw, Amnesty International, Iran HRM)
Monitors documented a second death sentence for Zahra Tabari, 68, reported cemetery record deletions at Behesht-e Zahra, and a poll showing 81.5% of medical residents want to emigrate, against a background of 200+ confirmed executions since February. Iran's security courts operate at uninterrupted wartime tempo regardless of the diplomatic track.
Pakistan (mediator)
Pakistan (mediator)
Islamabad carried Trump's revised MOU demanding HEU destruction to Iranian negotiators, 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.
Kuwait
Kuwait
Kuwait intercepted Iranian missiles and drones for a second time in days on 1 June, with air-raid sirens sounding nationwide, after invoking Article 51 self-defence on 28 May following the Ali Al Salem ballistic-missile strike. The repeated interceptions test whether Kuwait's domestic politics can sustain hosting US forces as a de facto co-belligerent.
China (PRC)
China (PRC)
Beijing sent scholars to Shangri-La rather than its defence minister and addressed Taiwan without mentioning Iran, maintaining bilateral energy corridor protection with Tehran while refusing diplomatic exposure at multilateral forums. Trump barred China as an HEU custodian on 27 May, removing Beijing from the deal architecture while China continues supplying DPI hardware that caps Iran's internet.

Lloyd's of London / war-risk underwriters
Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent recovered to $93.91, maintaining the structural divergence from futures pricing that has persisted since late May. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism.
Gulf Cooperation Council states (Saudi Arabia, UAE, Bahrain, Qatar)
Gulf Cooperation Council states (Saudi Arabia, UAE, Bahrain, Qatar)
Five Gulf states wrote to the IMO on 21 May rejecting Iran's PGSA transit authority over international waters; Saudi Arabia and the UAE have not confirmed participation in the European Hormuz mission. The GCC is navigating between US security guarantees and exposure to Iranian fire, with no Gulf state formally co-belligerent except Kuwait.
