Forget oil and gas, a bigger Iran war risk is shaping up

What Happened

• Beyond the well-publicised oil and gas threat, the Iran-Israel conflict is producing a less-noticed but potentially more damaging disruption: a global fertilizer supply shock that could drive up food costs and worsen India's fiscal deficit.
• Iran shut down seven of its urea and ammonia production plants after Israeli strikes targeted its natural gas infrastructure — the key feedstock for urea synthesis — raising fears of sustained production loss.
• Iran was the world's third-largest urea exporter in 2024, with export volumes of approximately 4.5 million tonnes and production capacity of ~8.9 million tonnes per year.
• Global urea prices jumped $60–80 per tonne as the Strait of Hormuz effectively closed, with approximately 33% of the world's fertilizer supply — from Qatar, Saudi Arabia, UAE, Iraq and Iran — transiting the strait.
• India, which is structurally dependent on fertilizer imports and runs a massive subsidy programme, faces both higher import costs and a sharply enlarged subsidy bill.

Iran's Role in Global Urea and Ammonia Markets

Urea (CO(NH₂)₂) is the world's most widely traded nitrogen fertilizer, synthesised from ammonia via the Haber-Bosch process using natural gas as feedstock. Iran's Zagros Petrochemical complex and several other petrochemical companies make it one of the largest urea exporters globally. Iran controlled 10–12% of global urea trade before the current conflict. The country is also the seventh-largest exporter of anhydrous ammonia (800,000 tonnes). Iran primarily serves markets in Turkey, Brazil, Argentina, and parts of South Asia. The shutdown of seven production plants — triggered both by direct strikes and by natural gas infrastructure damage — represents a structurally significant supply withdrawal, not merely a short-term logistics disruption.

India's Fertilizer Import Dependence and Subsidy Architecture

India is the world's second-largest consumer of fertilizers. While it domestically meets ~87% of urea requirements, it is structurally import-dependent for DAP (Di-Ammonium Phosphate) and completely import-dependent for MOP (Muriate of Potash). India imports 50–60% of its DAP requirements — primarily from Saudi Arabia (SABIC/Maaden), Jordan, Morocco and China — and 100% of MOP from Canada, Russia and Belarus. The fertilizer subsidy programme is governed under the Nutrient Based Subsidy (NBS) Scheme (launched 2010, covers P&K fertilizers) and the urea subsidy (governed separately under the New Urea Policy 2015). The government caps urea's retail price at ₹242/bag (45 kg) regardless of global cost, absorbing the difference as subsidy.

Strait of Hormuz and Fertilizer Trade Choke Point

Approximately 33% of the world's fertilizer supply transits the Strait of Hormuz. Qatar (urea + ammonia), Saudi Arabia (SABIC, DAP, urea), UAE, and Iran together make the Gulf the world's single largest fertilizer export hub. The Strait is 33 km wide at its narrowest, with two two-mile shipping lanes. Unlike oil, fertilizers cannot be easily stockpiled by importing countries (they degrade in moisture) — making supply disruptions acutely time-sensitive, particularly if they coincide with India's Kharif planting season (June–July) or Rabi sowing (October–November). LNG from Qatar (which also supplies feedstock gas for fertilizer plants) is also at risk: Qatar provides ~30% of China's LNG and roughly half of India's LNG supply.

Food Inflation and the Transmission from Fertilizer Prices to Consumer Prices

Fertilizer price shocks transmit to food prices through a well-documented channel: higher input costs → lower fertilizer application → lower yields → reduced supply → food price inflation. In India, this channel is partially buffered by MSP procurement and PDS distribution. However, the buffer is imperfect: vegetables, fruits and pulses — not covered under NFSA buffer stocking — are highly price-sensitive. India's Consumer Price Index (CPI) assigns ~46% weight to food and beverages, making food inflation the dominant driver of headline CPI. The RBI's monetary policy calculates that a 1 percentage point rise in food inflation pushes headline CPI up by 0.46 percentage points — compressing the RBI's room to cut rates even during growth slowdowns.
