Strait of Hormuz disruption severs fertiliser corridors as Northern Hemisphere planting begins
Over 30% of global urea exports transit the Strait of Hormuz. With maritime traffic severely disrupted at the start of the Northern Hemisphere planting window, yield consequences will become visible at harvest.
With shipments of fertiliser — of which about one-third passes through the Strait of Hormuz — disrupted, concerns about food prices are mounting. The interruption of crop-nutrient supplies from the Gulf comes just as planting season begins in the Northern Hemisphere, threatening yields and harvests through the year and pushing food prices higher.
Key data points
- Over 30% of global urea, widely used and produced from natural gas, is exported from Gulf countries through the Strait. Rising energy costs make basic food production — including corn and wheat — significantly more expensive. (IMF Blog, March 2026)
- Countries including Iran, Oman, Qatar, and Saudi Arabia are among the world's leading exporters of nitrogen fertilisers, including urea and ammonia. With maritime traffic severely disrupted and several production facilities damaged or temporarily closed due to security concerns, fertiliser supply chains have been heavily affected. (FAO, Global Agrifood Implications of the 2026 Developments in the Middle East, March 2026)
- The Strait's closure impacted the passage of around 20% of all seaborne fertiliser exports — mainly to Asia — potentially driving up global food production costs and posing inflationary pressures. (Middle East Economic Survey, April 2026)
Implication
The timing of this disruption is critical. Fertiliser is not easily stockpiled at farm level; disruption at the start of the Northern Hemisphere planting window will translate directly into reduced application rates or substitution with lower-quality inputs — with yield consequences becoming visible at harvest. Markets in South and Southeast Asia, which are heavily reliant on Gulf-origin urea, face the most acute near-term exposure.

Strait of Hormuz disruption blocks 30%+ of global urea transit during peak Northern Hemisphere planting → fertiliser shortages cascade through South and Southeast Asian supply chains → nitrogen prices spike 40-60% as importers scramble for alternative sources → yield losses of 10-15% materialise at harvest, compounding food inflation in import-dependent regions.
- South Asian fertiliser importers (India, Bangladesh, Pakistan): Face immediate 20% supply shortfall during critical kharif planting season. Emergency procurement from North Africa and Russia will carry 25-35% price premiums plus extended delivery times, forcing state subsidy budgets to expand or pass costs to farmers.
- Global nitrogen fertiliser traders (Trammo, Ameropa, Helm AG): Spot trading margins surge as arbitrage opportunities emerge between Gulf-contracted volumes and alternative origins. However, counterparty risk escalates on existing Gulf FOB contracts, with potential force majeure claims disrupting $2-3 billion in forward commitments.
- Southeast Asian rice and palm oil producers: Input cost increases of 30-40% on nitrogen fertiliser compress margins for Thai, Vietnamese, and Indonesian growers. Reduced application rates likely, with FAO models suggesting 8-12% yield drag on monsoon rice crop, tightening 2026 export availability.
- Losers: India's fertiliser ministry faces fiscal blowout as subsidy costs balloon by $4-6 billion to insulate farmers from price shocks. Bangladesh and Pakistan lack fiscal headroom for equivalent intervention, risking farmer defaults and reduced planted area. Vietnamese and Thai rice exporters see competitiveness erode against better-insulated Chinese production.
- Winners: North African exporters (OCP Group, Egypt's EBIC) and Russian producers (Uralchem, PhosAgro) capture redirected demand at premium pricing, with Moroccan urea exports potentially doubling quarter-on-quarter. US Gulf Coast producers (CF Industries, Nutrien) benefit from regionalisation as Western Hemisphere buyers reduce transit risk exposure.
