THE NEWS

According to Marine Insight, Qatar's Prime Minister visited Oman to advance negotiations involving Iraq, Iran, and other Gulf neighbours over the future governance of the Strait of Hormuz. These discussions are described as separate from any US-Iran peace process or de-mining operations, focusing instead on the long-term management of navigation through the waterway.

Reports indicate that Gulf states are likely to advocate for unrestricted, fee-free transit through the Strait, while Iran is expected to propose a navigation and security fee arrangement. Pakistan is also expected to participate as a mediator, and additional reconciliation talks between Gulf countries and Iran are planned for Riyadh.

In parallel, Oman announced two temporary maritime corridors — one north and one south of the Strait — developed in coordination with the IMO to facilitate the phased evacuation of vessels currently held on either side of the closure. Ships participating in the evacuation are required to maintain their AIS active throughout transit and to report any navigational hazards to the Oman Maritime Security Centre. Oman has clarified that independent risk assessments remain the responsibility of each vessel's captain and shipowner.

WHY IT MATTERS

The Strait of Hormuz closure, which followed military strikes against Iran, has disrupted roughly one-fifth of global oil and LNG supply flows. That single figure explains why diplomatic activity at this level — involving Qatar, Oman, Iraq, Iran, Gulf states, and Pakistan — is accelerating. The question for Brazilian offshore professionals is not whether the talks matter globally; it is how the outcome reshapes the competitive position of Brazilian crude and the cost structure of the Brazilian energy matrix.

The Atlantic basin premium is real, but temporary. With Persian Gulf volumes constrained, buyers in Europe and Asia have been redirecting procurement toward Atlantic basin suppliers. Brazilian pre-sal output — produced at scale by Petrobras and its consortium partners — has benefited from this redirection. A durable reopening of Hormuz would progressively narrow that premium as Gulf volumes return to market. The pace of diplomatic progress, and whether any fee regime is ultimately imposed on Hormuz transit, will determine how quickly and how sharply that compression occurs. A fee-based model, if adopted, would structurally alter the landed cost of Gulf crude into key markets and could sustain a partial premium for competing Atlantic grades even after physical flows resume.

The fee dispute is the central variable. The reported divergence between Gulf states (no transit fee) and Iran (navigation and security fee) is not a peripheral detail — it is the core commercial question that will determine Hormuz's role in global crude pricing for years ahead. If Iran succeeds in establishing a fee mechanism, every cargo transiting the Strait would carry an additional cost layer. That changes the economics of Gulf crude relative to competing grades, including Brazilian. If Gulf states prevail and the Strait reopens on a fee-free basis, the competitive landscape reverts more quickly toward pre-closure norms. Brazilian operators and traders should be modelling both scenarios.

LNG exposure is a distinct concern for Brazil. The disruption affects not only crude but also LNG flows, which are relevant to Brazil's own energy security. Brazil has expanded its LNG import infrastructure in recent years to support thermoelectric generation during hydrological stress periods. A prolonged Hormuz disruption tightens the global LNG market, elevates spot prices, and increases the cost of any Brazilian spot LNG procurement. Conversely, a managed reopening — even a partial one through Oman's temporary corridors — begins to relieve that pressure. The IMO's involvement in coordinating the evacuation corridors adds a layer of procedural legitimacy that may accelerate vessel operators' willingness to transit.

Operational risk remains elevated during the transition. Oman's evacuation framework — grouped departures, AIS requirements, mandatory hazard reporting — signals that the Strait is not yet in a normal navigational state. For any Brazilian operator or trading house with vessels or cargo commitments in the region, the framework places explicit responsibility on shipowners and masters for independent risk assessment. This is not a formality: it reflects genuine uncertainty about the navigational environment. P&I clubs and war-risk underwriters will be pricing that uncertainty into premiums, and those costs will flow through to cargo economics.

The Riyadh reconciliation track deserves attention. Alongside the Oman-based talks on Hormuz governance, regional reconciliation discussions between Gulf states and Iran are reported for Riyadh. This broader diplomatic track matters because durable Hormuz stability depends not only on a fee agreement but on a sustained reduction in regional tension. A governance deal reached without underlying political stabilization would remain fragile. Brazilian energy planners and procurement teams should treat the Riyadh track as a leading indicator of whether any Hormuz agreement will hold.

CONTEXT

The Strait of Hormuz has historically operated as a de facto global commons for energy transit, with freedom of navigation underpinned by a combination of international law and US naval presence. The current closure, and the negotiations now underway, represent a structural test of that framework. The MOU between the US and Iran — which reportedly includes a provision calling for Iran to engage Gulf neighbours on maritime navigation management — suggests that Hormuz governance is now a formal diplomatic agenda item rather than an assumed baseline.

For Brazil, which has navigated previous Gulf disruptions (including the 2019 Abqaiq attacks and earlier Hormuz tension episodes) largely as a price-taker in global markets, the current situation presents both a near-term pricing opportunity and a medium-term planning challenge. The outcome of the fee negotiations in particular will set a precedent that could outlast the current crisis and reshape the global crude trade architecture for the remainder of the decade.
