Fuel shortages from Iran war threaten Asia’s biggest food staple


What Happened

  • The six-week-old West Asia war (from February 28, 2026) has triggered a fuel and fertilizer supply crisis that is forcing rice farmers across Southeast Asia to delay harvests, skip planting seasons, and scale back sowing areas.
  • In Thailand — the world's second-largest rice exporter — farmers are leaving harvest-ready crops in the ground because diesel costs make harvesting economically unviable.
  • The disruption to the Strait of Hormuz has choked off approximately a third of the world's traded fertilizer, with urea shipments particularly affected; this cascades into lower output for the coming crop season.

The Strait of Hormuz and Global Commodity Supply Chains

The Strait of Hormuz is a 33-km-wide waterway between Iran and Oman connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the world's most critical oil chokepoint — approximately 21 million barrels of oil pass through it daily, representing about 20% of global oil trade. For India, the dependency is even deeper: roughly 90% of LPG imports and 50–53% of crude oil imports transit Hormuz.

  • Nearly half of the world's traded urea (the most widely used nitrogenous fertilizer) and large volumes of other fertilizers are exported from Gulf countries (UAE, Qatar, Saudi Arabia) via the Strait of Hormuz.
  • About a third of all fertilizer shipped globally transits Hormuz — its closure creates immediate upstream pressure on food production globally.
  • The 2026 Hormuz crisis has pushed urea prices up sharply, compounding the fuel cost squeeze on Asian farmers.

Connection to this news: Southeast Asian rice farmers are doubly squeezed — higher diesel costs raise mechanised harvesting and irrigation costs, while fertilizer shortages and price spikes reduce the economics of new planting cycles.

Food Security: Concepts and India's Framework

Food security, as defined by the FAO (1996 World Food Summit), exists when all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life. It rests on four pillars: Availability, Access, Utilisation, and Stability.

  • Rice is the staple food for more than 3.5 billion people globally; Southeast Asia (Thailand, Vietnam, Myanmar, Indonesia, Philippines) accounts for over 60% of global rice exports.
  • An extra 45 million people are projected to face acute hunger due to the ripple effects of the 2026 Iran war on food, oil, and shipping costs — pushing the global hungry past 319 million.
  • India is both a rice exporter and importer of fertilizers; disruptions to Gulf fertilizer trade directly affect Indian agricultural input costs.

Connection to this news: The Iran war demonstrates how a conflict thousands of kilometres from rice fields can create food insecurity within weeks through commodity supply chain disruption.

Fertilizer Economics and India's Agricultural Vulnerability

India is among the world's largest importers of fertilizers, particularly urea and DAP (Di-Ammonium Phosphate). India imports approximately 7–8 million tonnes of urea annually; domestic production (largely under the Urea Policy) covers only about 60% of demand. The government subsidises urea heavily — sold to farmers at ₹242/bag (50 kg) against a market cost often exceeding ₹700.

  • The Nutrient Based Subsidy (NBS) scheme covers DAP, MOP, and complex fertilizers but not urea (still under the older uniform pricing regime).
  • Major fertilizer exporters affected by the Hormuz closure: UAE (ADNOC), Qatar (QAFCO), Saudi Arabia (SABIC/SAFCO) — all routing exports through the Strait.
  • India, Brazil, and China — among the largest Gulf fertilizer importers — are also among the world's largest food producers, amplifying global food security risks from the supply disruption.

Connection to this news: A prolonged Hormuz closure could trigger a fertilizer supply shortage in India before the Kharif sowing season, threatening domestic food production.

Key Facts & Data

  • World's biggest rice exporters: India (40%), Thailand (15%), Vietnam (12%), Pakistan (8%) — Southeast Asian producers are on the front line of the current disruption.
  • ~1/3 of all globally traded fertilizer transits the Strait of Hormuz.
  • ~50% of global traded urea originates from Gulf states (UAE, Qatar, Saudi Arabia, Oman).
  • In Thailand, harvest-ready fields are being abandoned as diesel costs make mechanised harvesting unviable.
  • Extra 45 million people projected into acute hunger due to Iran war commodity spillovers (Bloomberg/IFPRI estimate).
  • India's annual fertilizer subsidy bill: approximately ₹1.6–1.8 lakh crore — any import price spike directly widens the fiscal deficit.
  • Strait of Hormuz width: approximately 33 km at its narrowest; 21 million barrels of oil pass through daily.
