Gas prices are screaming headlines, but a quieter, deeper crisis is unfolding that could hit the global food supply. As oil markets reel and drivers pay more at the pump, fertilizer shipments have been disrupted, exposing an overlooked link between hydrocarbons and the meals on our tables.
Energy shock: why oil grabs the spotlight
Brent crude raced past $100 a barrel after military strikes in late February. At one point, it nearly reached $119. Nations coordinated emergency measures, including the unprecedented release of 400 million barrels from strategic reserves.

Consumers saw the effect immediately. Gas station signs in some regions showed prices north of $5 a gallon. That visible pain focused public attention on fuel, and away from less obvious supply risks tied to the same energy sources.
Strait of Hormuz: a narrow route with wide consequences
The Strait of Hormuz has been effectively blocked to Western-allied commercial shipping for weeks. The waterway carries far more than crude oil. It also moves a large share of the world’s seaborne fertilizer trade.
- About one-third of global seaborne fertilizer transits the strait.
- Nearly half of global urea exports and roughly 30 percent of ammonia shipments pass through it.
When navigation stalls, fertilizer supply chains tighten as quickly as oil ones. That tightness arrives at planting time for many crops, magnifying its economic impact.
From methane to meals: the chemistry behind fertilizer
Fossil fuels matter not only for burning. They provide the raw molecules used to build essential materials. In modern agriculture, natural gas becomes the carbon and hydrogen inputs for ammonia production. That ammonia is then transformed into nitrogen fertilizers.
Scientists tracking global systems point out that this chain is fundamental. One scholar who studies energy and materials notes that cement, steel, plastics, and ammonia form core pillars of industrial life. Ammonia, produced today mostly via the Haber-Bosch process, is central to modern food production.
Without this process, experts estimate the planet could support far fewer people—perhaps only 3 to 4 billion—because synthetic nitrogen is responsible for a huge share of the food energy we now produce.
Regional damage: how the Gulf disruption ripples outward
The Persian Gulf nations are major fertilizer and LNG producers. Attacks during the conflict have damaged infrastructure that supplies both energy and fertilizer feedstocks. Company statements suggest some export capacity could be offline for years.
That matters because the same natural gas used for LNG is also the feedstock for ammonia plants. Reduced gas output can therefore shrink fertilizer production capacity long after oil prices calm.
Market effects are already visible. Urea prices climbed sharply as planting windows opened. Higher fertilizer costs raise input bills for farmers and can translate into lower yields or higher food prices later in the season.
Why crisis tools for oil don’t fix fertilizer shortages
Governments and international bodies have playbooks for oil shocks: reserve releases, rerouting pipelines, naval escorts, and multinational coordination. Those measures protect a high-value commodity that global markets track closely.
Fertilizer lacks comparable crisis infrastructure. There are no widespread strategic fertilizer reserves among major economies. Transport routes and new pipelines tend to favor crude oil. Captains risking transit will usually prioritize heavier-paying cargoes, like oil, over ammonia.
Who stands to lose the most
Countries that import fertilizer appear most at risk. Some rely heavily on Gulf LNG and fertilizer shipments to hit seasonal planting deadlines.
- India imports a significant share of its LNG and could see domestic urea output curtailed ahead of the monsoon season.
- Brazil is the world’s largest fertilizer importer and depends on supply chains exposed to the Middle East.
- Many nations in sub-Saharan Africa remain vulnerable after earlier price shocks reduced fertilizer use. Aid mechanisms that once backstopped shortages are less certain today.
When supply tightens, wealthier buyers often secure limited cargoes first, leaving poorer importers to cope with reduced volumes and higher costs.
Where the energy transition helps — and where it falls short
Renewables have transformed power systems in some countries. Solar and wind now furnish large shares of electricity in parts of Europe. Electric vehicles and grid decarbonization reduce oil demand.
Yet electricity is only a fraction of total final energy use. The chemical uses of hydrocarbons—making ammonia, plastics, and steel—remain largely fossil-fuel dependent. Alternatives exist in theory. For example, green ammonia uses renewable electricity to produce hydrogen for Haber-Bosch. But at present, it is a negligible share of global ammonia output.
Scale is the key barrier. Building renewable hydrogen and retrofitting or replacing global ammonia capacity would take years and vast investment. That means short-term famine risk remains tied to fossil-fuel supply disruptions.
Practical responses policymakers and industry can pursue
Some measures could reduce the immediate vulnerability of food systems to energy disruptions. These steps vary in cost and speed of implementation.
- Establish strategic fertilizer stockpiles in major importing nations.
- Promote regional fertilizer manufacturing to reduce dependence on long-distance shipping.
- Incentivize accelerated deployment of green hydrogen and pilot green ammonia plants.
- Support targeted subsidies or emergency aid to farmers facing input-price shocks during critical planting periods.
- Enhance maritime security for critical seaborne commodities beyond oil.
Decision-makers face trade-offs between rapid, short-term relief and long-term structural changes. The current episode exposes that those trade-offs matter more than many realized.
