Iran’s Demands Keep Strait of Hormuz Shut as Oman-Led Shipping Deal Nears, Extending Pressure on Energy and Food Supply Chains

Iran’s insistence that the Strait of Hormuz will remain closed until the United States meets broad political and economic demands is prolonging a historic disruption to global energy flows and key maritime trade routes. An Oman-brokered arrangement for new shipping lanes is reportedly close to agreement, but Tehran has made clear that implementation depends on Washington lifting sanctions, ending the naval blockade and compensating Iran for war damage, delaying any near-term normalization of traffic through the chokepoint. In parallel, Iran‑aligned Houthi forces have stepped up attacks in the Red Sea and Gulf of Aden, including claimed strikes on Saudi Aramco’s Jazan refinery and vessels linked to Gulf energy interests, raising risks across an alternative corridor that has absorbed some of the traffic diverted from the Persian Gulf. The combination of a prolonged Hormuz shutdown and renewed Red Sea insecurity is tightening logistics for crude, products and dry bulk cargoes, with knock‑on effects for agricultural commodity flows and freight costs.

Introduction

Since February 28, 2026, when the United States and Israel launched large‑scale strikes on Iran, Tehran has effectively closed the Strait of Hormuz to foreign shipping, halting most tanker and gas carrier movements through a passage that previously carried roughly one‑fifth of global seaborne oil and a significant share of LNG exports. The United States subsequently imposed a naval blockade on Iranian ports, preventing outward sailings and deepening the stand‑off.

Over the past several days, Iranian and Omani officials have moved closer to a technical routing arrangement that would, in principle, reopen the strait using separate inbound and outbound lanes near Iranian and Omani waters. However, Iran’s leadership has publicly tied any reopening to far‑reaching US steps, including lifting sanctions, releasing frozen assets and paying extensive war reparations, conditions Washington has so far resisted. This linkage keeps commodity markets focused on the risk of an extended period of constrained flows through Hormuz.

Immediate Market Impact

The continued closure of Hormuz and the uncertainty around the Oman‑mediated deal are sustaining a risk premium in crude benchmarks and regional grades, even as recent ceasefire talk had briefly pressured spot prices lower. With around 20–25% of pre‑war seaborne oil and a major share of Qatari and Emirati LNG historically moving through the strait, any delay in reopening constrains available export capacity from key Gulf producers and keeps tanker utilization and freight rates elevated.

For agricultural markets, the immediate impact is felt through higher bunker fuel costs, longer voyage distances as vessels avoid high‑risk zones, and tighter availability of certain ship classes as energy flows tie up tonnage. At the same time, reports of Houthi attacks on Saudi infrastructure and commercial shipping in the Red Sea corridor complicate rerouting strategies, increasing insurance premia and voyage times for Black Sea, Mediterranean and South Asian grain and oilseed cargoes destined for Asia and the Middle East.

Supply Chain Disruptions

Port and channel congestion has shifted north and west of Hormuz as exporters and importers seek alternative terminals and routes. Saudi Arabia and the UAE have attempted to redirect some crude and product exports via Red Sea and Arabian Sea ports, but infrastructure and pipeline constraints limit how much displaced volume can be absorbed in the short term. LNG and LPG exporters are similarly constrained, which tightens global shipping availability and raises freight costs for refrigerated and containerized agricultural goods.

In the Red Sea and Bab‑el‑Mandeb region, Houthi attacks on tankers and cargo vessels and the claimed strikes on Saudi Aramco’s Jazan refinery and terminal complex on the Red Sea coast have created new bottlenecks just as traffic from the Gulf has been rerouted. Some shipowners are increasingly opting for the longer voyage around the Cape of Good Hope, adding 10–15 days to typical Europe–Asia runs and tying up tonnage that would otherwise serve grain, sugar and edible oil trades.

Commodities Potentially Affected

• Crude oil and refined products – Directly affected by the Hormuz closure, with reduced Gulf export capacity and higher freight and insurance costs supporting elevated price volatility and regional price differentials.
• LNG and LPG – Qatar and other Gulf exporters face constrained routes, tightening Atlantic and Asian gas balances and indirectly raising power generation costs for energy‑intensive agrifood industries.
• Wheat and coarse grains – Key exporters in the Black Sea, EU and North America shipping to MENA and Asia rely heavily on Suez/Red Sea routes; heightened insecurity and diversions increase voyage times and freight rates.
• Rice and sugar – Indian, Thai, Brazilian and Pakistani flows to the Middle East and East Africa often transit the Arabian Sea and Red Sea; disruptions and higher bunkers raise landed costs and may widen regional basis levels.
• Vegetable oils and oilseeds – Palm oil exports from Southeast Asia and soybean/meal flows from the Americas to MENA and South Asia face similar routing and freight challenges, with potential for higher CIF values and delayed arrivals.
• Fertilizers – Gulf producers of urea, ammonia and phosphates are exposed to Hormuz logistics, while Red Sea risks affect flows from North Africa; tighter supply chains could lift benchmark fertilizer prices, impacting farm input costs globally.

Regional Trade Implications

Middle Eastern exporters with alternative outlets—such as Saudi Arabia’s Red Sea ports and UAE terminals outside the most exposed zones—may gain relative competitive advantage, but their capacity to offset the loss of Hormuz throughput is limited. Gulf producers without robust alternative export routes face steeper revenue losses and may need to curtail output, tightening global availability of both energy and petrochemical‑derived inputs used in agriculture.

Import‑dependent countries in the Middle East, North Africa and South Asia are particularly vulnerable, as they rely on both stable crude and LNG inflows and affordable seaborne grain and food imports. European and Asian buyers may increasingly diversify sourcing, favoring origins with more secure logistics—such as Atlantic Basin crude and LNG, or grain shipped via safer northern routes—potentially re‑shaping trade patterns and freight spreads.

Market Outlook

In the near term, the market’s baseline is for prolonged negotiation and episodic escalation rather than a rapid reopening of Hormuz, given the breadth of Iran’s public demands and the political difficulty for Washington in meeting them. As a result, traders should expect persistent logistics tightness, elevated war‑risk premia and continuing sensitivity of crude, product and freight markets to headlines from Muscat, Tehran and Washington.

For agricultural commodities, the primary transmission channel will remain freight and energy costs, plus localized availability issues where rerouting is complex or uneconomic. Volatility spikes are likely around any announcements on a Hormuz corridor deal, confirmed infrastructure damage in the Red Sea, or changes in naval protection policies. Market participants will closely monitor actual shipping movements, insurance pricing and port status updates, rather than political statements alone, to gauge when risk premia in both energy and food supply chains may start to ease.

CMB Market Insight

The current phase of the Strait of Hormuz crisis has evolved from a pure military confrontation into a high‑stakes regulatory and access dispute over one of the world’s most critical maritime chokepoints. By explicitly linking navigational freedom to sanctions relief and compensation, Iran has effectively weaponized shipping access as a negotiating lever, with outsized consequences for global energy and, indirectly, agricultural markets.

For commodity traders and supply‑chain managers, managing this environment means assuming continued disruption across both the Gulf and Red Sea theatres, stress‑testing exposure to longer routes and higher freight, and reassessing contract terms that hinge on specific passages or just‑in‑time delivery. Until a credible, enforceable framework for safe, depoliticized transit through Hormuz and the Red Sea emerges, elevated logistical risk is likely to remain a structural feature of global commodity trade.
