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.

Different Perspectives
Oil markets and Lloyd's of London
Oil markets and Lloyd's of London
Brent fell to $89.25 on ceasefire probability, not new barrels, with traders voting for Trump's deed over Tehran's denial. Lloyd's has not repriced Hormuz war-risk cover because its trigger requires a UN Security Council resolution or government certification, so tanker insurance costs remain elevated regardless of the spot move.
Pakistan and Qatar mediators
Pakistan and Qatar mediators
Pakistan's Mohsin Naqvi was in Tehran for his second visit in under a week, using the Pakistan-Qatar channel that delivered April's ceasefire after an identical public-denial cycle. The channel carries both civilian and military buy-in from Islamabad, the only configuration Iran's split command cannot dismiss as a partial signal.
India
India
India summoned the US Deputy Chief of Mission after three Indian sailors were killed aboard MT Settebello, the first formal grievance from a major non-belligerent directed at US enforcement. Indian seafarers supply roughly 12 per cent of the global maritime workforce; their presence on third-flag Gulf tankers is structurally inevitable regardless of bilateral diplomacy.
Islamic Revolutionary Guard Corps (IRGC)
Islamic Revolutionary Guard Corps (IRGC)
The IRGC declared Hormuz closed on 11 June while civilian negotiators were on the same mediation channel, then issued no public comment on the MoU framework. Its silence on the framework, rather than any foreign ministry statement, is the operative approval signal; the corps' unilateral Hormuz closure shows it did not treat the diplomatic track as binding on its operations.
Iran foreign ministry (Baghaei)
Iran foreign ministry (Baghaei)
Esmail Baghaei told IRNA that reports of a finalised deal were 'merely speculation' and that Iran had 'not yet made a final decision'. The denial is structurally identical to Iranian foreign ministry statements during the April ceasefire talks, which produced a binding text within 48 hours of the same language.
Trump administration / CENTCOM
Trump administration / CENTCOM
Trump cancelled the third strike day and called the MoU 'very strong' and almost ready to sign, while CENTCOM kept tanker enforcement running in the same 24-hour window. The administration is simultaneously withdrawing the military pressure it claims drove the deal and sustaining the enforcement campaign it is trying to trade away.
