Hormuz Crisis Deepens as Iran War Hits Gulf Shipping and Food Import Routes

The monthlong U.S.-Israel war with Iran and Tehran’s tightening grip on the Strait of Hormuz are now spilling directly into commercial shipping, with a Kuwaiti oil tanker hit off Dubai and container vessels trapped in the Gulf. While the primary shock is in energy markets, the same routes underpin critical flows of food and agri-inputs into the Gulf and beyond, raising freight costs and supply risk. Traders across grains, sugar, rice, edible oils and fertilizers face a higher-premium, higher-volatility environment in the near term.

With Iran maintaining an effective closure of Hormuz to much tanker traffic and striking vessels in wider Gulf waters, food-import-dependent states such as Saudi Arabia, the UAE, Kuwait, Qatar and Bahrain are increasingly exposed. Alternative ports and longer reroutes are absorbing some volumes, but at the cost of sharply higher freight, insurance and fuel prices that will ripple through global agricultural supply chains.

Introduction

The conflict escalated further this week as U.S. forces reportedly used 2,000-pound bunker-buster bombs against a large ammunition depot in Isfahan, central Iran, underscoring the intensity of the air campaign. At sea, Iranian attacks have targeted commercial shipping, including a Kuwaiti oil tanker struck off Dubai, which caused a fire but no reported oil spill, according to local authorities.

Since early March, Iran has effectively restricted traffic through the Strait of Hormuz in response to U.S.-Israeli strikes, drastically reducing oil and LNG exports from Gulf producers. Estimates suggest shipping through the strait has fallen by more than 95%, with over 130 container ships trapped inside the Gulf and dozens more waiting outside, as war-risk premiums and missile, drone and sea-drone threats deter transit.

🌍 Immediate Market Impact

Energy markets have reacted sharply, with Brent crude up around 60% over the month as Gulf oil exports plunge and Iran keeps Hormuz largely closed to tankers. Diesel benchmarks in key consuming regions have surged as well, reflecting both crude tightness and rerouting via longer passages. Higher bunker and diesel costs are feeding directly into ocean freight and inland logistics rates for containerized and bulk agri-shipments.

For agricultural commodities, the immediate effect is less about outright supply loss and more about logistics friction and cost inflation. GCC states import over 80% of their calories by sea, much of it via Hormuz; by mid-March, an estimated 70% of their food imports were disrupted, forcing major retailers to rely on costly airlifts and alternative routes, with consumer food prices reportedly jumping 40–120%. This environment is supportive for CIF Gulf prices across staple grains, sugar and rice, and it raises basis and freight spreads globally.

📦 Supply Chain Disruptions

The closure and high-risk status of Hormuz has stranded or delayed container and bulk carriers, including at least 130 boxships inside the Gulf and over 60 waiting outside the strait. These bottlenecks are disrupting scheduled liner services that typically move foodstuffs, refrigerated cargoes and agricultural inputs into Gulf ports. While some Gulf terminals continue to operate, vessel turnarounds are increasingly constrained by security protocols and limited safe windows.

Iranian missile and drone attacks have also hit infrastructure in Gulf states, including energy and industrial sites in Saudi Arabia, Kuwait and the UAE, adding localized power and logistics risks. At the same time, Pakistan’s Karachi port complex has reported a historic cargo surge, including petroleum and container traffic, partly reflecting diversions around the Gulf and Hormuz. This redirection of flows is lengthening transit times for Asia–Europe and Asia–Africa routes that handle significant volumes of agri-commodities.

📊 Commodities Potentially Affected

• Wheat and coarse grains – Heavy import dependence in GCC states and parts of North Africa means disrupted Gulf logistics and higher freight costs can lift delivered prices and tighten nearby availabilities.
• Rice – Key suppliers to the Middle East (India, Pakistan, Thailand, Vietnam) rely on Gulf transshipment and direct calls; diversions to alternative ports and airfreight for premium grades push up CIF values.
• Sugar – The region is a major importer of raw and refined sugar; extended routes and war-risk insurance premiums add to costs and may tighten regional refining margins and inventories.
• Vegetable oils and oilseeds – Sunflower, soybean and palm oil flows into the Middle East face higher freight and insurance costs, with potential for localized shortages in bottled oils if container services are curtailed.
• Meat and dairy products – Chilled and frozen protein imports via reefer containers are vulnerable to port delays and schedule disruptions, raising spoilage and demurrage risks.
• Fertilizers and agri-inputs – The Gulf is a core exporter of urea, ammonia and other nitrogen products; Hormuz disruption tightens global fertilizer availability and raises input costs for growers, especially in Asia and Latin America.

🌎 Regional Trade Implications

Traditional Gulf importers are already seeking to diversify entry points. Increased volumes through ports in Pakistan and the Red Sea suggest a gradual reconfiguration of regional logistics, with Karachi and possibly Omani and East African ports emerging as alternative hubs. However, these diversions add sailing days, reposition equipment away from normal lanes and absorb limited feeder capacity.

Exporters with flexible routing options stand to benefit. Black Sea and Mediterranean origins serving the Middle East and North Africa can redirect cargoes via Suez and non-Gulf transshipment hubs, potentially gaining share at the expense of suppliers more tied to Gulf logistics. Meanwhile, Asian and European importers of Gulf-origin fertilizers and petrochemicals face tighter supply and may pivot to alternative producers, including North Africa and North America, supporting prices for those exporters.

🧭 Market Outlook

In the short term, agricultural markets are likely to see elevated freight rates, wider basis differentials and episodic price spikes tied to any new attacks on shipping or port infrastructure. With Iran signaling its continued grip over Hormuz and Gulf allies urging Washington not to end the campaign prematurely, traders should assume a protracted period of constrained Gulf logistics.

Key monitoring points include: any move toward limited shipping corridors through Hormuz under Iranian or international guarantees; further strikes on commercial vessels beyond the immediate strait; and policy responses such as stock releases or temporary tariff adjustments by major importers. The balance between incremental rerouting and outright demand rationing in the Gulf will shape global trade flows in staples over the next quarter.

CMB Market Insight

The 2026 Hormuz crisis is evolving from a primarily energy shock into a broader maritime trade disruption with systemic implications for agricultural supply chains. Even if physical grain and oilseed production remains unaffected, the combination of higher fuel prices, war-risk premiums, and route diversions is tightening delivered availability and inflating costs for import-dependent markets.

For commodity traders, importers and food industry buyers, this argues for proactive freight risk management, diversified routing and origin strategies, and closer monitoring of Gulf inventory levels. Until a durable de-escalation or shipping arrangement is in place, the Gulf will remain a high-cost, high-risk node in global agri-commodity trade, with the potential to amplify volatility from any future supply or demand shocks elsewhere.
