The ink is barely dry on the US-Iran peace accord signed last week, but the real battle for control of global trade has already shifted from Switzerland to Muscat. When Iran and Oman announced a joint working group on Tuesday to manage navigation through the Strait of Hormuz, global shipping executives immediately rang the alarm bells. If you thought the end of the naval blockade meant a permanent return to free shipping, you missed the fine print of the Islamabad Understanding.
The competitor reports focused on the simple diplomatic fact that Oman and Iran are talking. They missed the seismic shift underneath. This isn't just a routing discussion. It’s an aggressive attempt by Tehran to codify long-term authority over the world's most critical energy choke point, potentially introducing unprecedented fees that could permanently alter global shipping economics.

The user searching for this news wants to know one fundamental thing. Will oil and cargo flow freely, or are we looking at a hidden tax on global commerce? The short answer is that while ships are moving today, the era of a completely free, unregulated Strait of Hormuz might be over in sixty days.
Understanding Clause 5 and the Sixty Day Countdown
To understand why these meetings in Muscat matter, you have to look at Clause 5 of the recently signed US-Iran memorandum of understanding. Under the deal, Iran agreed to ensure safe, toll-free passage for commercial vessels for exactly 60 days while it clears mines and technical obstacles. Further analysis by The Washington Post highlights related views on the subject.
But what happens on day 61?
That's exactly what Iranian Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi went to Oman to figure out. Ghalibaf hasn't hidden his intentions. In an interview on Iranian state television, he stated bluntly that the strait will not return to pre-war conditions and that Tehran has the right to receive a fee for services rendered to passing ships.
Oman find itself in a delicate spot. Its territorial waters hug the western side of the strait. While Omani Foreign Affairs Minister Badr Albusaidi publicly stated that Muscat supports toll-free safe passage, the joint statement issued by both nations explicitly says the new working group will negotiate the future administration of navigation, services, and associated costs.
The shipping industry feels blindsided. Organizations like Intertanko, the prominent international tanker industry body, are already pushing back. Phillip Belcher, the marine director for Intertanko, made it clear that the final outcome of these regional discussions must reinforce the central tenet that the Strait of Hormuz remains entirely free of transit charges.
The Legal Shell Game Between Tolls and Service Fees
There is a massive legal discrepancy happening here that most mainstream media outlets are completely glossing over. It centers on the United Nations Convention on the Law of the Sea, known widely as UNCLOS.
Iran signed UNCLOS back in 1982 but never actually ratified it. Under Article 26 of the convention, nations cannot levy charges upon foreign ships simply for their passage through territorial waters. Levies can only be executed as payment for specific services rendered to the ship, like pilotage or towing.
Tehran’s legal teams are using this exact loophole to construct their argument. They aren't calling the proposed charges a toll. President Donald Trump even claimed on Wednesday that Iran told the US no tolls were being sought. Technically, that might be true. But Iran is drawing a sharp line between a flat transit toll and what it terms service fees, environmental mitigation charges, and maritime insurance mechanisms.
If Iran successfully establishes a joint administrative authority with Oman, they can claim that managing the traffic lanes, providing weather tracking, positioning rescue boats, and monitoring environmental pollution constitute active services. They want to model the system after the Strait of Malacca, where littoral states manage a joint fund, though Malacca does not charge mandatory direct transit fees to passing merchant ships.
Look at the math to understand what's at stake. On a single typical day, roughly 19 million barrels of oil flow through that narrow stretch of water. During the height of the recent military conflict, Tehran effectively halted traffic by claiming the lanes were mined, at one point demanding a staggering two million dollar fee payable in bitcoin for safe passage. Even a fraction of that amount applied as a standardized service fee would generate billions in annual revenue for a cash-strapped Iranian regime trying to rebuild its economy.
Why Saudi Arabia and the UAE Are Furious
The Muscat talks aren't just making Western shipping lines nervous. They are driving a massive wedge between the Arab Gulf states. Saudi Arabia and the United Arab Emirates view any joint Iranian-Omani management mechanism as a direct threat to their sovereign economic interests.
Saudi Foreign Minister Prince Faisal bin Farhan Al Saud didn't mince words when addressing the proposed framework. He pointed out that the management of the strait worked perfectly fine before the conflict broke out. There were no safety issues, no major environmental crises, and ships navigated freely. He openly questioned why the region should accept a novel, restrictive arrangement imposed as the byproduct of a war.
The UAE has even deeper scars from the recent hostilities. Emirati policymakers note that their infrastructure, hotels, and civilian sites took direct hits during the conflict. The idea that they would now have to pay service fees to the country responsible for those disruptions to export their own oil is a non-starter in Abu Dhabi.
Oman’s willingness to sit down with Iranian negotiators has created intense friction within the Gulf Cooperation Council. Muscat has long prided itself on being the regional mediator, the bridge between Tehran and the West. But this time, its neighbors feel Oman is giving away too much leverage over a global waterway that belongs to international commerce, not just the two states sitting on its shores.
What Shipping Companies Should Expect Next
If you run logistics, manage supply chains, or operate maritime assets, you can't afford to sit back and celebrate the temporary peace deal. The next two months will determine your long-term operating costs through the Middle East.
The Institute for the Study of War notes that establishing a joint mechanism gives Iran a tool to regulate transit and potentially restrict passage under the guise of administrative safety. While tankers from major companies like China's Cosco have restarted transit through the channel, the maritime insurance market is still pricing in extreme risk.
The US administration claims it wants a proper security framework to ensure the straits are never used as an economic choke point again. Vice President JD Vance has played down the tolling aspect, focusing instead on long-term stability. Yet, the reality on the water is that Iran's Supreme National Security Council has already ordered its Persian Gulf Strait Authority to route vessels according to strict, state-mandated schedules, citing remaining safety hazards.
Actionable Steps for Maritime and Energy Operators
Do not wait for the 60-day window to expire before adjusting your corporate strategy. Take these concrete steps immediately to protect your operations from the fallout of the Oman-Iran negotiations.
- Audit Charter Party Agreements: Review all active and upcoming charter agreements. Ensure there are explicit, updated clauses defining who bears the financial burden if mandatory service fees, environmental levies, or state-run insurance charges are implemented by a Persian Gulf Strait Authority.
- Diversify Export Routes: Maximize utilization of alternative pipelines that bypass the choke point entirely, such as Saudi Arabia’s East-West Pipeline or the UAE’s Habshan–Fujairah pipeline, even if they incur higher initial transit tariffs.
- Update Risk Assessments with Underwriters: Meet with your maritime insurance providers to re-evaluate hull and machinery coverage. Don't assume rates will drop permanently just because the blockade was lifted; insurers are tracking the implementation of Iranian-mandated routing schedules very closely.
- Establish a Regulatory Watch Team: Assign policy analysts to track the specific outcomes of the newly formed Muscat-Tehran working group. The critical items to watch are the definitions of services provided and whether they match international maritime definitions or function as disguised transit fees.
