Iran–Oman Edge Toward Hormuz Revenue Deal as Blockade Persists, Keeping Energy Flows Constrained

Iran and Oman are moving closer to a structured framework for managing the Strait of Hormuz, including an agreement on sharing transit revenues and territorial waters. But with Tehran insisting the strait will not fully reopen until US conditions are met, global oil and LNG flows remain heavily constrained and freight risks elevated despite modest easing in prices.

Negotiations between Tehran and Muscat have intensified in recent days, with Iranian officials and the Revolutionary Guard Corps (IRGC) saying understandings have been reached on each country’s share of the strait’s waters and future revenues from transit fees. However, Oman and other Iranian officials have stopped short of confirming a final accord, while Iran maintains that any reopening of the strategic corridor depends on US compliance with earlier understandings and the lifting of the naval blockade on its ports.

Introduction

The latest talks follow a joint Iranian–Omani statement outlining a proposed temporary shipping corridor and mine-clearance project to restore safer navigation through the Strait of Hormuz, which has been largely shut for nearly six months of conflict. Before the war, the 21-mile choke point carried roughly one-fifth of global crude and liquefied natural gas exports from Gulf producers to world markets.

While Iran’s deputy foreign minister and IRGC spokesmen have portrayed recent understandings as a significant breakthrough, they have also underlined that the waterway is not yet open and that commercial traffic would initially be routed through carefully controlled lanes. Attacks on vessels and the blacklisting of 45 ships allegedly involved in ship-to-ship transfers continue to deter shipowners and underwriters, reinforcing the effective blockade of a route critical to global energy and petrochemical trade.

Immediate Market Impact

Oil benchmarks have eased more than 1.5% since news of renewed mediation and the prospective Hormuz corridor, as traders price in a slightly lower tail risk of a prolonged total closure. But the lack of a formal, enforceable agreement and ongoing security incidents are limiting any sustained downside, keeping risk premia embedded in crude, LNG and tanker freight markets.

Spot and prompt cargoes from key Gulf exporters remain subject to longer routes, higher insurance premia and scarce ship availability as many operators avoid the blacklisted fleet and exposures near the strait. This is supporting elevated freight rates on alternative routes via the Red Sea and regional pipelines, while capping the degree to which lower flat oil prices translate into cheaper landed costs for refiners and importers.

Supply Chain Disruptions

Port operations across the Gulf continue to feel the strain of restricted Hormuz access, with congestion and schedule uncertainty affecting crude and LNG loadings, refined product exports and containerized agrifood shipments. With the United States maintaining a naval blockade on Iranian ports, Iranian-origin cargoes in particular face complex routing, documentation and insurance hurdles, constraining their participation in regional supply chains.

The IRGC’s warning that 45 named vessels risk seizure and fines if they engage in ship-to-ship transfers with Gulf producers has introduced an additional layer of operational risk. Some charterers and energy companies are shunning not only the blacklisted tankers but also counterparties linked to them, narrowing available tonnage pools and delaying liftings of crude, condensate and NGLs. These knock-on effects are disrupting feedstock availability for petrochemical complexes and raising logistics costs for bulk food and fertilizer shipments that share regional port and tanker infrastructure.

Commodities Potentially Affected

• Crude oil: Directly exposed as around 20% of global seaborne oil flows historically transited Hormuz. Persistent restrictions support a structural risk premium in Brent and Middle Eastern benchmarks and complicate supply planning for refiners.
• LNG: Gulf LNG exporters reliant on Hormuz face shipping delays and higher freight and insurance costs, pressuring delivered prices into Asia and Europe and tightening spot availability during demand spikes.
• Refined products (diesel, gasoline, jet fuel, LPG, naphtha): Disruptions to regional refineries’ crude intake and outbound shipping increase volatility in Asian and African product markets and may widen spreads for Middle East–origin cargoes.
• Petrochemical feedstocks (naphtha, ethane, propane) and derivatives: Higher energy and freight costs raise production costs for polymers and intermediates, with downstream effects on packaging, textiles and industrial inputs for the food and beverage sector.
• Agricultural commodities and food products: While grains and oilseeds are less directly tied to Hormuz volumes, container and breakbulk food cargos using Gulf ports face delays, rerouting and higher bunker and insurance costs, feeding into import prices for Middle East and South Asian buyers.

Regional Trade Implications

Major Gulf oil and gas exporters are accelerating use of alternative outlets, including pipelines to the Red Sea and Arabian Sea, where available, and shifting some incremental volumes to buyers able to accept longer lead times and higher logistics costs. Countries with diversified import routes or access to strategic reserves, notably in Europe and Northeast Asia, are better positioned to smooth supply, while more price-sensitive importers in South and Southeast Asia face greater exposure to freight and premium volatility.

Iran and Oman’s emerging revenue-sharing framework for Hormuz raises the prospect of new transit fees and service charges if the corridor reopens, which would alter cost structures for all shipping nations using the passage. However, with Tehran conditioning any reopening on US sanctions relief, compensation and an end to the naval blockade, uncertainty over the timeline and terms of restored traffic is likely to keep some buyers diversifying away from Gulf-origin energy and petrochemical feedstocks where possible.

Market Outlook

In the near term, crude and LNG markets are likely to remain headline-driven, with price swings tied to perceived progress or setbacks in Iran–Oman–US diplomacy and any new security incidents around Hormuz. The announced understandings on territorial and revenue shares are a necessary step toward a managed reopening, but not sufficient to normalize flows as long as attacks on vessels and the US port blockade persist.

Commodity traders will closely monitor concrete milestones: formal confirmation of a temporary corridor with agreed safety guarantees, observable increases in tanker and LNG carrier transits, changes to US sanctions enforcement and insurance market assessments of war risk. Until these materialize, elevated freight rates, periodic supply scares and a persistent risk premium in energy-linked commodities are likely to remain features of the market landscape.

CMB Market Insight

For energy, petrochemical and agrifood participants, the evolving Iran–Oman framework for Hormuz management signals a potential path out of the current choke point disruption, but not an imminent return to normal trade patterns. Pricing, hedging and procurement strategies should continue to assume constrained Gulf export capacity, heightened freight and insurance costs, and episodic volatility driven by geopolitics rather than fundamentals alone.

Importers with exposure to Gulf-origin fuels and feedstocks may find value in diversifying suppliers, securing longer-term contracts with flexible delivery windows and exploring hedges on both flat prices and freight. Exporters and logistics providers, meanwhile, will need contingency plans that account for both a gradual reopening—with possible new transit fees—and the risk of renewed escalation that could again curtail flows through the world’s most critical energy artery.
