US-Iran deal opens way for Hormuz charges, shipping industry warns

The new US-Iran accord reopening the Strait of Hormuz has prompted immediate concern across the shipping industry that one of the world’s most important trade chokepoints could stop being toll-free.

Shipping executives and carriers warned that the agreement could open the door to transit charges or a maritime-services fund, a change that would affect tankers, LNG carriers, insurers and the wider energy market.

The Strait of Hormuz handles a large share of global oil and gas flows, so even a limited fee regime could quickly raise transport costs and ripple through fuel markets.

What changed

The Financial Times reported that the deal has created new uncertainty over whether passage through the strait will remain free or become fee-bearing.

The Guardian separately reported that Iran has announced plans to bring in maritime fees for ships passing through the waterway within two months, after a memorandum of understanding with the United States.

Business Insider said the agreement reopens the strait and begins a phased lifting of the US naval blockade, with the blockade expected to end within 30 days.

Taken together, the reports suggest the immediate change is not a finalized toll system but the start of a broader negotiation over how the strait will be governed.

Why the shipping industry is alarmed

For operators, the issue is not only the size of any charge but the precedent it could set.

If one coastal authority can impose a payment on passage, carriers fear other states could seek similar arrangements in major international waterways.

That would complicate pricing, insurance and route planning for companies that move crude oil, refined products and gas through the region.

Shipping groups would also likely press for clarity on whether any charge is a narrow payment for services or a broader transit toll in practice.

The legal question

The main legal reference point is the United Nations Convention on the Law of the Sea.

Article 26 says foreign ships cannot be charged merely for passage through territorial seas, and that charges are allowed only as payment for specific services rendered.

That distinction matters because a service fee and a transit toll are not the same thing.

A fee tied to pilots, safety, escorting or other defined services may be easier to defend than a broad levy on simply crossing the strait.

Any broader interpretation would likely draw legal challenge and diplomatic pushback.

The chronology so far

The immediate public warning came in the Financial Times on June 18, which said shipping executives were already worried the accord could change the economics of using Hormuz.

Later reporting from the Guardian said Iran was planning maritime fees within two months, although the formal signing event tied to the memorandum had been cancelled and technical talks were continuing.

Business Insider then described the arrangement as reopening the strait while the US begins lifting its naval blockade, with a 30-day window for the blockade to end.

That sequence leaves the market with a still-fluid picture: a reopened waterway, a possible fee proposal, and no settled public framework for how access will be managed.

Who is involved next

The reporting points to Iran, Oman and other Gulf states as the parties that would shape any longer-term management framework.

That matters because any durable system would likely need regional buy-in, not just a bilateral understanding.

It is also unclear whether any future charges would be limited to specific services or whether they would function like a transit charge in practice.

The reported two-month timetable for maritime fees has not been confirmed in a formal public text, so that timeline still appears provisional.

Why it matters

The Strait of Hormuz remains one of the world’s most sensitive maritime routes for energy shipments.

Any move toward tolls or service fees would affect tankers, LNG carriers, shipowners, insurers and traders that rely on predictable access through the passage.

It would also invite scrutiny from Gulf governments and from shipping interests that favor open access.

For now, the central question is whether the new deal becomes a narrow service-based framework or the start of a broader fee regime that changes how one of the world’s key waterways is used.
