What Happened
- Beyond the widely discussed oil price surge, analysts warn that the US-Israel-Iran conflict and the resulting Strait of Hormuz disruptions pose an equally dangerous — and less discussed — threat to global fertilizer supply chains
- Iran is a significant producer of natural gas, the primary feedstock for ammonia and urea (nitrogen fertilizers), and has halted domestic fertilizer production following the conflict
- QatarEnergy — operator of the world's largest LNG and industrial complex at Ras Laffan — halted urea, ammonia, and methanol output following Iranian drone strikes on the facility
- Approximately one-third of globally traded urea transits the Strait of Hormuz, meaning a sustained blockade cuts off a major fraction of global nitrogen fertilizer trade
- Urea prices rose approximately $60–80 per ton in the days following the Hormuz closure, a jump of roughly 15–17% from pre-war levels (~$470/ton), with further increases expected if disruptions persist
- The timing is particularly damaging: fertilizer demand peaks before spring planting in the northern hemisphere, meaning supply disruptions of even a few weeks can force farmers to reduce application rates or shift crop choices

Natural Gas as the Backbone of Global Fertilizer Production
Nitrogen fertilizers — urea, ammonium nitrate, and diammonium phosphate (DAP) — are produced through the Haber-Bosch process, which combines atmospheric nitrogen with hydrogen to produce ammonia. The hydrogen feedstock is overwhelmingly derived from natural gas (methane). This means that the global nitrogen fertilizer industry is fundamentally a natural gas processing industry: gas prices directly determine fertilizer production costs, and gas supply disruptions translate immediately into fertilizer supply disruptions. The Persian Gulf region — including Qatar, Iran, and Saudi Arabia — accounts for a major share of global LNG and natural gas exports. Qatar alone supplies approximately 11% of global urea exports; combined with other Gulf producers, the Persian Gulf accounts for roughly 45% of global urea export volumes.
- Haber-Bosch process: N₂ + 3H₂ → 2NH₃ (ammonia); hydrogen sourced from natural gas (steam methane reforming)
- Natural gas: accounts for ~70–80% of the cost of producing ammonia globally
- Qatar: ~11% of global urea exports; Persian Gulf collectively: ~45% of global urea exports
- ~30–33% of globally traded urea transits the Strait of Hormuz
- Iran: significant urea and ammonia producer; has halted output since conflict began
- QatarEnergy (Ras Laffan): world's largest LNG complex; urea/ammonia production halted
Connection to this news: The Hormuz closure simultaneously cuts off Iranian production, impedes Qatari exports, and blocks the shipping lane used by one-third of global urea trade — a triple blow to nitrogen fertilizer availability.
Global Food Security and Fertilizer Shocks
The link between fertilizer availability and food production is direct: nitrogen is the single most yield-limiting nutrient in global agriculture, and nitrogen fertilizers are responsible for sustaining the food production capacity that feeds approximately half of the world's population (according to estimates based on Haber-Bosch process contributions). When fertilizer prices spike or supplies are disrupted, farmers face a choice: pay more (and pass costs to consumers through food prices), reduce application rates (and accept lower yields), or shift to less fertilizer-intensive crops. Each of these choices has food security implications. The 2022 fertilizer shock — triggered by the Ukraine war and Russia/Belarus export restrictions — saw urea prices peak at over $900/ton and contributed to food price inflation globally.
- Haber-Bosch process: estimated to sustain food production for ~50% of global population
- 2022 fertilizer price shock: urea peaked at >$900/ton (vs. ~$470/ton pre-Iran-war in 2026)
- Food price transmission: fertilizer cost increases → higher crop production costs → retail food price inflation
- Subsistence farmers most vulnerable: cannot absorb higher input costs or shift production easily
- UN FAO monitors fertilizer price and availability as a leading indicator of food security stress
- Spring planting timing: delays in fertilizer delivery of even 2–4 weeks can significantly reduce yields
Connection to this news: The Iran war fertilizer shock risks replicating — or exceeding — the 2022 shock, with the critical difference that it arrives just as the northern hemisphere enters its primary planting season, compressing the window for farmers to adapt.
India's Domestic Urea Production and LNG Dependence
India is the world's second-largest consumer of fertilizers and one of the largest importers of urea. India's domestic urea production relies heavily on natural gas as feedstock. A significant portion of the natural gas used in India's urea plants is imported LNG, primarily from Qatar and other Persian Gulf sources. When Persian Gulf LNG supplies are disrupted (as during the Hormuz crisis), Indian urea plants face input shortages and are forced to reduce output — meaning that higher import prices coincide with lower domestic production, creating a double-sided supply squeeze. The government's fertilizer subsidy bill — already one of the largest budget line items — expands automatically when fertilizer input or import costs rise, because retail urea prices are heavily subsidised and fixed for farmers.
- India: world's second-largest fertilizer consumer
- India's domestic urea capacity: ~26 MMTPA; supplemented by ~9–10 MMTPA of imports
- Feedstock for Indian urea plants: natural gas (domestic + LNG imports from Qatar/Gulf)
- Three Indian urea plants reduced output as Persian Gulf LNG supplies fell (March 2026)
- India's fertilizer subsidy: ~₹1.7 lakh crore budgeted for FY25 (one of the largest budget items)
- A 30% rise in fertilizer import prices → significant expansion of subsidy outgo unless retail prices are raised
Connection to this news: India faces a compound vulnerability: domestic production falls as LNG inputs are disrupted, while import costs for finished fertilizers also rise — squeezing supply from both ends precisely as Kharif season preparation begins.
