The World Bank Warned the Iran War Could Cause a Global Food Crisis — Here Is How Bad It Gets

The World Bank issued its most serious food security warning since 2022. Here is the specific commodities affected, which countries are most at risk, and the timeline of impact.

The World Bank's April 3 warning about 'mounting risks to inflation, jobs and food security worldwide' from the Iran war's energy disruption is the specific institutional acknowledgement of an economic cascade whose individual components are visible in specific market data but whose aggregate effect is best captured in the World Bank's specific analytical framework.

The commodity transmission chain: natural gas is the feedstock for nitrogen fertiliser production. Elevated natural gas prices — up approximately 60 percent from pre-war levels — directly increase the cost of nitrogen fertiliser, whose production is energy-intensive enough that gas price doubling approaches doubling of production cost. Nitrogen fertiliser is the most widely used agricultural input globally, applied to approximately 60 percent of all crop production. A 40 percent fertiliser price increase — the current market indication — translates into crop production cost increases whose magnitude varies by crop and farming system but that average approximately 15-20 percent in wheat production.

For the specific at-risk populations: the World Bank's food security modelling identifies approximately 50 countries as significantly exposed to the current commodity price shock. The specific highest-risk nations include: Yemen (pre-existing severe food insecurity, high import dependence, local infrastructure destroyed by previous conflict); Egypt (the world's largest wheat importer, whose subsidised bread programme is the specific government commitment most exposed to wheat price rises); Bangladesh (import-dependent food system with specific LNG-dependent power sector); and multiple sub-Saharan African nations whose specific combination of import dependence and fiscal constraint makes absorption of commodity price shocks extremely difficult.

For the timeline: the specific lag between commodity price increases and food price increases at the consumer level is 2-4 months in most markets. The current commodity price increases will appear in retail food prices approximately in June-July 2026 — the specific timing that places the food impact in the middle of the northern hemisphere summer and exactly when the World Cup is occurring in the United States.

For the global political dimension: food price crises have specific historical correlations with political instability, particularly in the Middle East and North Africa where the Arab Spring of 2011 was preceded and partly triggered by the specific food price spike of 2010-2011.
