Stronger U.S. Dollar and Iran–Red Sea Tensions Reshape Commodity Risk Landscape

The U.S. dollar has strengthened as renewed tensions between the United States and Iran, including threats to Red Sea and Strait of Hormuz shipping, push investors into safe‑haven assets. At the same time, energy markets remain on edge after reports that Iran has asked Yemen’s Houthis to prepare to disrupt Red Sea oil flows if U.S. strikes target Iran’s power infrastructure. This macro‑geopolitical mix is reshaping risk, pricing and trade flows across energy and agricultural commodity markets.

While oil prices have eased slightly from recent highs, they remain elevated, reflecting persistent concerns over potential chokepoint disruptions. The firmer dollar is tightening global financial conditions, particularly for import‑dependent emerging markets that price commodities in U.S. currency, raising the risk of demand destruction in price‑sensitive food and feed segments.

Introduction

According to recent reports, Iran has asked Yemen’s Houthi movement to be ready to close the Red Sea oil route via the Bab al‑Mandab gateway if the United States strikes Iran’s power network, with Houthi forces said to have deployed missiles and drones near key Red Sea approaches. This comes on top of an existing U.S. naval blockade and repeated clashes around the Strait of Hormuz that have already disrupted tanker traffic and raised freight and insurance costs.

These developments arrive amid a broader “new energy shock” in which Middle East conflict has become a central driver of higher and more volatile global energy prices and weaker growth expectations, particularly in Europe. In this environment, the U.S. dollar has drawn safe‑haven inflows, supported further by relatively resilient U.S. macro data, amplifying cost pressures for dollar‑funded commodity importers worldwide.

Immediate Market Impact

For energy, the immediate risk is a dual‑chokepoint scenario: renewed disruption in the Strait of Hormuz combined with potential attacks or closures around Bab al‑Mandab and the southern Red Sea. A significant share of seaborne crude and oil products from the Gulf transits these corridors; any credible threat of closure or attacks typically widens risk premia in Brent and Dubai benchmarks, steepens forward curves and lifts volatility in fuel spreads.

The stronger dollar magnifies these moves in local‑currency terms for net importers, especially in Europe and Asia, where higher energy costs are already weighing on growth and inflation dynamics. For agricultural commodities, dollar appreciation tends to put downward pressure on dollar‑denominated prices on global exchanges but can simultaneously increase local‑currency costs for importing nations, complicating procurement and hedging decisions.

Supply Chain Disruptions

A Red Sea escalation would directly affect one of the world’s busiest maritime corridors, through which a significant volume of oil, oil products, fertilizers and containerized foodstuffs passes between Asia, the Middle East and Europe. Previous Houthi attacks on ships in the Red Sea have already demonstrated the potential for rerouting around the Cape of Good Hope, lengthening voyages, tightening vessel availability and raising freight and insurance premia.

For agricultural supply chains, longer routes and higher freight costs could erode arbitrage margins on Black Sea and EU grain into the Middle East and East Africa, and on Asian rice and sugar flows toward Europe and North Africa. Containerized food products, edible oils and specialty ingredients moving between Asia, the Gulf and Europe would be most exposed to schedule disruptions and higher logistics costs.

Commodities Potentially Affected

• Crude oil and refined products – Direct exposure to Hormuz and Bab al‑Mandab transit; heightened risk of supply interruptions and higher freight and insurance costs support elevated prices and volatility.
• LNG and pipeline‑linked gas – European and Asian gas benchmarks are sensitive to Middle East supply risks; higher oil‑indexed contract prices and risk premia could spill over into power and fertilizer sectors.
• Nitrogen fertilizers (urea, ammonia, UAN) – Elevated gas and freight costs from the Gulf raise export prices, impacting importers in Europe, Latin America and Africa and feeding through into crop production costs.
• Grains and oilseeds (wheat, corn, soy, barley) – Higher bunker and freight costs for Black Sea, EU and Americas exports into MENA and Asia may widen regional basis levels and alter typical trade lanes.
• Edible oils and sugar – Palm, sunflower oil and white sugar shipments that rely on Red Sea transits could see cost inflation and delivery risk, particularly for buyers in the Horn of Africa and the Levant.
• Metals and bulk raw materials – While secondary to energy, any sustained rerouting around Africa tightens dry‑bulk and tanker markets, indirectly raising logistics costs for ores, coal and other industrial inputs.

Regional Trade Implications

Europe, already facing a weaker growth outlook tied to higher energy prices and external shocks, is particularly exposed on both the cost and demand sides. Elevated fuel, fertilizer and freight costs weigh on margins for EU farmers, food processors and exporters, while a stronger dollar and slower growth in key importing regions may cap demand for high‑value processed foods.

Conversely, non‑Gulf energy exporters such as the United States, Brazil and West African producers could benefit from any rerouting of flows or substitution away from Gulf‑origin crude and LNG. Agricultural exporters in the Americas and Black Sea region might find additional demand in MENA markets seeking to diversify suppliers, though they will also bear higher shipping costs and FX‑related volatility.

For import‑dependent economies in North Africa, the Middle East and South Asia, the combination of a firmer dollar, elevated energy and fertilizer prices, and potential Red Sea disruptions raises food security and balance‑of‑payments risks. Policymakers in these regions may respond with tariff adjustments, subsidy schemes or strategic stockbuilding, further influencing trade patterns.

Market Outlook

In the near term, commodity markets are likely to remain headline‑driven, with price action closely tracking any confirmation of attacks on shipping, U.S. strikes on Iranian infrastructure, or moves by Houthis toward actual closure of Bab al‑Mandab. As long as flows through Hormuz and the Red Sea continue, risk premia should be contained but elevated, with options volatility staying bid in oil and refined products.

For agricultural markets, the main transmission channel is via energy, freight and FX rather than direct physical shortages. Traders will monitor bunker surcharges, vessel availability, insurance conditions for Red Sea routes and central bank signals on interest‑rate paths in major economies, given their impact on the dollar and on financing costs for inventories and hedges.

CMB Market Insight

The conjunction of a stronger U.S. dollar with a renewed Middle East maritime risk premium marks a shift into a more complex risk environment for commodity supply chains. Energy and freight shocks are increasingly intertwined with monetary conditions and FX dynamics, especially for import‑dependent regions.

For commodity traders, importers and food industry players, this argues for tighter integration of FX, freight and energy hedging strategies, more diversified routing and supplier portfolios, and active monitoring of Red Sea and Hormuz developments. Until geopolitical tensions ease decisively, elevated cross‑asset volatility and episodic disruption risk will remain central features of the global commodity landscape.
