Why rising commodity prices threaten food security beyond the oil market

The World Bank’s October 28 Commodity Markets Outlook projects a 23% increase in overall commodity prices in 2026, driven principally by a 32% surge in energy prices. Its forecast for internationally traded food commodities is a rise of about 10% this year followed by another 7% in 2027. These are forecasts rather than confirmed price outcomes, and they do not translate directly into supermarket inflation in every country.

The transmission channels explain why the outlook matters well beyond oil producers. Energy is used to manufacture fertilizer, operate farm equipment, refrigerate produce and transport grain. A prolonged increase in its cost can therefore reach households through several stages of the food chain. The Bank expects fertilizer prices to climb 14% in 2026. Conflict-related shipping disruptions and a strong El Niño add separate threats to agricultural supply and distribution.

The risks are uneven. Countries dependent on imported fuel and staple foods face different pressures from exporters, while exchange rates, tariffs, subsidies and domestic harvests shape local outcomes. Higher international prices do not prove that every family will pay the same increase. The Food and Agriculture Organization reported that its international food price index rose 1.5% in September, another indication of pressure, not a prediction of the final retail bill.

The World Bank’s adverse scenario envisages food commodity prices 12% above its baseline if several shocks intensify together. That conditional scenario should not be confused with the central forecast. The practical conclusion is that governments need to monitor transport and fertilizer costs alongside headline oil prices, protect vulnerable consumers where budgets permit, and avoid assuming that easing one bottleneck will automatically stabilize the whole food system.
