Gulf War Fertilizer Supply Crisis - Strait of Hormuz Blockade 2026

On February 28, 2026, coordinated military strikes by the United States and Israel against Iran triggered a full-scale regional conflict across the Persian Gulf. Iran retaliated by launching missiles and drones at U.S. military bases in Qatar, Kuwait, Bahrain, and the United Arab Emirates, and its Revolutionary Guard Corps (IRGC) issued radio warnings via VHF declaring the Strait of Hormuz closed to all maritime traffic. Within 48 hours, commercial shipping through the strait came to a near-complete halt. While global attention focused primarily on surging oil prices, the disruption unleashed a severe and largely underestimated crisis in the global fertilizer market.

The Strait of Hormuz is the single most critical maritime chokepoint for the global fertilizer trade. Approximately one-third of the world's nitrogen fertilizer exports transit through this 21-mile-wide waterway, including roughly 25% of all internationally traded urea and a comparable share of anhydrous ammonia. Qatar, Saudi Arabia, the UAE, Oman, and Iran collectively account for close to half of global seaborne urea exports. Unlike crude oil, for which nations maintain strategic petroleum reserves, there is no equivalent global buffer stock for fertilizers. The industry operates almost entirely on a just-in-time logistics model, making it acutely vulnerable to sudden shipping disruptions.

The timing of the conflict could hardly have been worse for global agriculture. Northern Hemisphere spring planting was imminent, with farmers across the United States, Europe, and South Asia preparing to apply nitrogen-based fertilizers to corn, wheat, and rice fields. March and April represent the peak months for urea imports into the United States, and any vessel loading in the Persian Gulf would require approximately 30 days to reach American ports, followed by another three to four weeks of inland distribution. The window for spring fertilizer application was already closing rapidly when the strait became effectively impassable.

Direct production shutdowns compounded the shipping crisis. Iranian fertilizer manufacturers suspended output at all seven of their urea and ammonia plants, partly due to fears of Israeli strikes on industrial infrastructure and partly because of damage to natural gas supply networks used as feedstock for ammonia synthesis. Iran ranks among the world's top ten urea producers, exporting approximately 4.5 million tons of urea and 800,000 tons of anhydrous ammonia annually, and controls between 10% and 12% of global urea trade.

The disruption cascaded beyond Iran. Israel ordered the suspension of production at its offshore Leviathan and Karish gas fields as a precautionary measure following the regional escalation. Egypt, which depends heavily on Israeli gas imports to power its fertilizer manufacturing sector, was forced to halt urea production after gas flows were curtailed. This repeated a scenario already experienced during a previous Israel-Iran confrontation in mid-2025, when severed gas deliveries knocked all Egyptian urea output offline for weeks. Jordan, another energy-dependent fertilizer producer in the region, faced similar constraints as gas prices surged.

QatarEnergy announced the suspension of all operations at its Ras Laffan and Mesaieed Industrial City facilities, halting not only LNG production but also sulphur output. Qatar's sulphur production capacity stands at approximately 3.8 million tons per year, representing around 8% of global seaborne sulphur trade. Sulphur is a critical raw material for phosphate fertilizer manufacturing, and its sudden unavailability sent additional shockwaves through the phosphate supply chain.

Fertilizer prices reacted immediately and sharply. In New Orleans, the primary U.S. trading hub, urea barge prices surged by approximately $70 per ton over a single weekend, jumping from around $457 per ton on Friday to roughly $550 per ton by Monday. Egyptian granular urea prices rose by $60 per metric ton within days. European ammonia futures spiked to $725 per ton on the ICE exchange, an increase of $130 per ton from the previous trade two weeks earlier. Saudi Arabia raised its urea export price to $450 per ton FOB, up substantially from $402. According to Trading Economics data, global urea spot prices climbed from $470 to $531 in just four days.

The crisis struck a market already under significant stress from multiple simultaneous supply constraints. China had extended its export restrictions on phosphates and urea through at least August 2026, removing the world's largest fertilizer exporter from the international market to protect domestic food security. A recent Ukrainian drone strike had damaged one of Russia's largest nitrogen fertilizer plants, tightening global ammonia and urea availability further. European nitrogen production was operating at only about 75% of capacity due to persistently high natural gas costs, exacerbated by the implementation of the EU Carbon Border Adjustment Mechanism (CBAM) on January 1, 2026. U.S. retail fertilizer prices were already at or near historic highs for the time of year before hostilities commenced, with urea having surpassed $600 per ton in February.

The countries most vulnerable to a prolonged disruption span multiple continents. India, the world's second-largest fertilizer consumer, imports heavily from Gulf producers and depends on Qatari LNG to fuel its own domestic manufacturing plants. Brazil sources roughly one-third of its fertilizer imports from Oman and Qatar. Turkey relies significantly on Iranian fertilizer supply. Across Sub-Saharan Africa and South Asia, including Ethiopia, Niger, Bangladesh, and Thailand, farmers operating on thin margins face the prospect of being priced out of fertilizer markets entirely if costs continue to rise.

Insurance and freight costs have added another layer of disruption. War-risk premiums for vessels transiting the Persian Gulf have surged, and several major shipping insurers have withdrawn coverage entirely. Even if fertilizer cargoes could be loaded, the cost of insuring and transporting them has become prohibitive for many buyers. Vessels that attempt alternative routing via the Cape of Good Hope face additional weeks of transit time and roughly $1 million in extra fuel costs per voyage.

Analysts and industry executives have warned that the agricultural consequences could be severe if the disruption persists beyond a few weeks. In the United States, some farmers may shift planted acreage from nitrogen-intensive corn to soybeans if fertilizer supplies fail to arrive in the Corn Belt in time. Globally, reduced fertilizer application during critical spring growing periods could translate into lower crop yields for late 2026 harvests, driving food price inflation across major staple commodities including corn, wheat, and rice. The World Food Programme and agricultural economists have drawn parallels to the 2022 fertilizer crisis triggered by the Russia-Ukraine war, when prices tripled and contributed to a global hunger emergency.

As of early March 2026, the situation remains highly fluid. Middle Eastern fertilizer producers have largely suspended spot market offers and are awaiting clarity on the duration of the conflict and the status of the Strait of Hormuz. Buyers across North Africa, Southeast Asia, and the Americas are scrambling to secure alternative supplies, but the global market lacks sufficient spare capacity to replace the volumes normally flowing through the Gulf. The fertilizer supply crisis represents one of the most consequential and underreported dimensions of the 2026 Persian Gulf conflict, with direct implications for global food security in the months ahead.
