Competing US–Iran Conditions Keep Strait of Hormuz Partially Shut, Prolonging Energy and Agri-Commodity Trade Disruptions

Restoration of normal commercial traffic through the Strait of Hormuz remains elusive as Iran and the United States harden their positions on the terms for reopening the strategic waterway. Tehran is linking any reopening to sanctions relief and an end to the US naval blockade of Iranian ports, while Washington insists on full freedom of navigation without new Iranian controls or fees. This policy deadlock is sustaining elevated risk levels for global oil, LNG and related agricultural supply chains.

Following the collapse of a temporary truce in mid-June, Iran has continued to threaten or interfere with vessels, while US forces have redirected or disabled ships attempting to breach the blockade around Iranian ports. Maritime security assessments now classify the broader Gulf region as a severe-risk zone, with mines and intermittent attacks constraining traditional shipping lanes through Hormuz. The resulting uncertainty is reshaping tanker routes, freight costs and availability of key inputs such as fuel, fertiliser feedstocks and food-grade gases.

Immediate Market Impact

Although US officials say nearly 9 million barrels per day are still moving through the Strait of Hormuz via escorted or alternative lanes near Oman, volumes remain well below pre-war norms, and access is uneven across flag states and cargo owners. Iran continues to signal that long-term reopening would involve a new routing regime with entry near Iranian waters and exit near Oman, potentially tied to maritime service fees, while US policymakers reject any arrangement that formalises Iranian control or charges on international transit.

War-risk insurance premiums for Gulf transits remain elevated, and some owners have withdrawn tonnage rather than risk sanctions exposure or mine damage. This is sustaining a tight tanker market and higher freight rates on Middle East–Asia and Middle East–Europe lanes, with knock-on price effects for crude, refined products and LNG. Energy-linked agricultural cost structures, including diesel for farming and transport, nitrogen fertiliser production and cold-chain logistics, continue to face upward pressure as traders price in prolonged volatility around Hormuz.

Supply Chain Disruptions

Mine contamination of central shipping channels has forced commercial vessels closer to either Iranian or Omani territorial waters, where protection varies and legal risks differ. Several hundred tankers and dry cargo ships are reported to be stranded or idling in the wider Persian Gulf as they await clearer security guarantees, routing instructions or political decisions.

The effective closure or restriction of Iranian ports under the US naval blockade is also disrupting exports of petrochemicals, fertiliser components and industrial gases that feed into global food production and processing. At the same time, regional alternative routes—from Saudi Red Sea ports to pipelines bypassing Hormuz—are near capacity and exposed to spillover attacks, particularly from Houthi forces around the Bab el‑Mandeb and Red Sea corridor. These constraints are lengthening voyage times, increasing demurrage and raising delivered costs for energy and agri-bulk cargoes into Europe, North Africa and Asia.

Commodities Potentially Affected

• Crude oil and oil products – Hormuz normally handles a large share of global oil exports; ongoing restrictions and elevated risk premiums are keeping benchmark prices and regional differentials volatile.
• Liquefied natural gas (LNG) – Qatar and other Gulf producers rely on Hormuz; constrained LNG flows and higher freight and insurance costs feed into power and industrial costs worldwide.
• Nitrogen fertilisers (urea, ammonium nitrate, UAN) – Gulf-based production dependent on natural gas faces higher export and freight costs, with some volumes delayed or rerouted via longer paths, impacting global fertiliser availability and pricing.
• Phosphate and potash trade flows – While major producers lie outside the Gulf, higher bunker costs, vessel scarcity and regional congestion are lifting delivered prices into key import markets in South Asia and East Africa.
• Edible oils and sugar – Refiners and re‑export hubs in the Gulf face higher input and shipping costs, which can widen CIF prices into MENA and South Asia, especially where cargoes rely on backhaul capacity of product tankers.
• Food‑grade industrial gases (CO₂, helium) – Disruptions in Gulf helium and gas logistics add incremental cost and supply risk for beverage, packaging and cold-chain applications.

Regional Trade Implications

Middle Eastern exporters are accelerating use of bypass infrastructure, including pipelines and Red Sea ports, to maintain flows to Europe and Asia, but these alternatives carry higher marginal costs and limited spare capacity. Gulf producers with diversified export routes—such as Saudi Arabia via Red Sea terminals—are relatively better positioned, though exposed to Houthi attacks, while Iran remains heavily constrained by the US blockade and secondary sanctions risk.

On the import side, Asian buyers are increasingly sourcing incremental crude, LNG and fertilisers from the US, West Africa and Russia, reshaping tanker patterns and creating longer average voyage distances. European refiners and fertiliser producers face tighter competition for Atlantic Basin supplies and higher freight into the Mediterranean, potentially eroding margins and raising wholesale fuel and input prices. Net food-importing countries in MENA and South Asia are particularly vulnerable to combined energy and fertiliser cost shocks, which may filter through into higher grain and staple food prices over coming months.

Market Outlook

With Iran and the US maintaining incompatible conditions for a comprehensive reopening of Hormuz, markets are increasingly pricing in a prolonged period of partial closure and elevated security risk, rather than a quick normalisation. Oil and LNG markets are likely to remain highly headline‑sensitive, with any incident involving mines or vessel attacks triggering short‑term price spikes and widened time spreads.

For agricultural markets, the most immediate transmission channels are through energy, fertiliser and freight. Traders will monitor: progress of Iran–Oman routing talks; any shift in US blockade policy; updated war‑risk insurance designations; and utilisation rates on bypass pipelines and Red Sea routes. A durable de‑escalation could ease freight and input costs, but absent such a breakthrough, elevated volatility and risk premia are likely to persist into the next planting and procurement cycles.

CMB Market Insight

The Hormuz standoff has evolved from a short‑term shock into a structural shipping and policy constraint for global commodity flows. For energy‑intensive agricultural value chains, this translates into a higher and more volatile cost base for fuel, fertilisers and logistics, particularly into MENA, South Asia and parts of Europe.

Commercial hedging strategies should assume continued chokepoint risk, with emphasis on freight and input‑cost risk management rather than reliance on a rapid political resolution. Procurement and trading teams may benefit from diversifying origin options where feasible, locking in forward freight where liquidity allows, and closely tracking policy signals from Washington, Tehran and Muscat that could redefine access conditions and fee structures for Hormuz transits.
