A growing geopolitical crisis in the Middle East is raising alarms across global agricultural markets. While most attention has focused on the potential disruption to oil and gas shipments, experts say the conflict could also ignite a new surge in global food prices. The reason lies in the strategic importance of the Strait of Hormuz, one of the world’s most critical shipping corridors for both energy and agricultural inputs.

The narrow waterway connects the Persian Gulf with the open ocean and handles roughly a fifth of the world’s oil supply. However, it is also a major transit route for fertilizers that are essential to modern agriculture. If the conflict leads to prolonged shipping disruptions, analysts warn the effects could ripple through global food systems, increasing farming costs, squeezing crop yields, and ultimately pushing grocery prices higher for millions of households.

Why the Strait of Hormuz Matters for Global Food Supply

The Strait of Hormuz serves as a vital logistical artery for fertilizer exports from major Gulf producers including Qatar, Saudi Arabia, Oman, and Iran. These countries together account for a significant share of global urea and phosphate fertilizer production, materials widely used to boost crop yields around the world.

Agricultural economists warn that even a temporary disruption to these shipments could quickly affect farming operations. Fertilizers are among the most important inputs in modern agriculture, and many countries depend heavily on imports to sustain crop production.

Higher fertilizer costs tend to spread rapidly across the entire food supply chain. Farmers facing rising input prices often reduce fertilizer usage to manage expenses, which can lead to lower crop yields. In turn, reduced harvests can tighten global food supplies and drive up prices for staple foods such as wheat, rice, and maize.

Energy costs compound the problem. Fertilizer production relies heavily on natural gas, meaning that spikes in energy prices often translate directly into higher fertilizer prices. With oil and gas markets already reacting to geopolitical tensions in the region, agricultural costs could climb on multiple fronts simultaneously.

Gulf Countries Face Immediate Food Supply Risks

The nations closest to the conflict may experience the earliest disruptions. Several economies in the Gulf Cooperation Council rely heavily on imported food delivered through shipping routes that pass directly through the Strait of Hormuz.

Countries such as Qatar, Bahrain, Kuwait, and Saudi Arabia import a large share of their food due to limited agricultural capacity and challenging climates. If shipping traffic through the strait becomes restricted, food shipments may need to be rerouted through longer maritime corridors or transported overland.

Such alternatives are significantly more expensive and logistically complex. In extreme scenarios, countries may even resort to air transport for essential food supplies, which dramatically increases costs.

Wealthier Gulf states generally have the financial resources to absorb these higher costs in the short term. However, nearby economies facing political or economic instability could struggle to maintain stable food supplies if disruptions persist.

Iraq and Iran themselves may also encounter supply challenges if maritime trade flows become severely constrained.

Sub-Saharan Africa Could Face the Harshest Consequences

While Gulf nations may feel the impact first, the most severe long-term consequences could emerge thousands of kilometers away in sub-Saharan Africa. Many countries in this region rely heavily on imported fertilizers and spend a large portion of household income on food.

In several African economies, more than 90 percent of fertilizers used in agriculture are imported, often from suppliers in the Middle East or other global markets that depend on shipping routes through Hormuz.

A disruption in fertilizer availability or a sharp increase in prices could severely affect crop production. Staple crops such as maize, which is a primary food source across large parts of the region, require nitrogen-based fertilizers to maintain yields.

Lower fertilizer use could translate into weaker harvests, reduced food supplies, and higher prices for basic staples. For households that already allocate a significant portion of income to food purchases, even modest price increases could lead to serious economic hardship.

Densely populated and low-income areas would likely feel the pressure most strongly.

South and Southeast Asia Also Face Rising Costs

The agricultural economies of South and Southeast Asia could also face mounting challenges if fertilizer supply chains tighten. Countries such as India, Bangladesh, Indonesia, and Thailand depend heavily on fertilizer imports to sustain their large-scale agricultural sectors.

Many of these imports originate in the Gulf region or travel through the Strait of Hormuz before reaching Asian markets. If shipping costs rise or supplies become limited, farmers across the region may face sharply higher expenses during key planting seasons.

This could affect the production of staple crops such as rice and maize, both of which require substantial fertilizer inputs to maintain productivity. A surge in input costs could therefore ripple through regional food markets and place upward pressure on consumer prices.

For farmers who already operate on thin profit margins, a sudden increase in fertilizer costs combined with higher fuel prices could create significant financial strain.

Global Agricultural Powerhouses Could Also Feel the Impact

The effects of a fertilizer supply shock would not be limited to developing economies. Major agricultural exporters such as Brazil could also encounter rising costs if fertilizer markets tighten.

Brazil is one of the largest producers of soybeans, maize, and other key agricultural commodities, yet it imports approximately 85 percent of the fertilizer used in its farming sector. Much of that supply arrives through global shipping networks that could be affected by disruptions in the Middle East.

If fertilizer shipments are delayed or become more expensive during Brazil’s key import periods, farmers may face higher production costs. In the longer term, this could influence global commodity markets, since Brazil plays a central role in supplying food and animal feed to countries around the world.

Any decline in Brazilian crop output or increase in production costs could therefore have a cascading effect on global food prices.

Energy Costs Could Amplify Food Inflation

Even if fertilizer supplies remain relatively stable, rising energy prices alone could push food costs higher worldwide. Energy plays a central role in nearly every stage of the food supply chain.

Fuel powers farm machinery, irrigation systems, and transportation networks. Natural gas is a primary ingredient in the production of nitrogen-based fertilizers. Energy is also required for food processing, refrigeration, packaging, and distribution.

When oil and gas prices increase sharply, those higher costs are often passed along through the entire food system. This is why geopolitical conflicts in energy-producing regions frequently translate into broader inflation across food markets.

The Duration of Disruptions Will Determine the Impact

The ultimate scale of any food price shock will depend largely on how long disruptions in the Strait of Hormuz persist. Short-term shipping delays could cause temporary price spikes, but global markets may stabilize if trade routes reopen quickly.

However, a prolonged disruption could have more serious consequences. Extended fertilizer shortages, sustained energy price increases, and rising transportation costs could combine to create a powerful inflationary cycle in global food markets.

With the world already facing fragile supply chains and climate-related agricultural pressures, the risk of another major food price surge remains a growing concern for policymakers, farmers, and consumers alike.
