Wheat climbs a fourth straight month as cereals defy a stable headline index
The FAO food index held near a three-year high in May; underneath, weather, fuel and fertilizer costs pushed all major grains higher
Summary
The Fao Food Price Index averaged 130.8 points in May 2026, broadly flat month-on-month but 2.9% above a year earlier. Beneath the stable headline, the Cereal Price Index rose 2.6% from April and nearly 5% year-on-year. World Wheat prices climbed for a fourth consecutive month on smaller expected harvests in major exporters; US Hard Red Winter ran ~28% above May 2025. The All Rice Index rose 2.7% on weather concerns and crude-linked costs. Russian and Ukrainian supplies are tempering the rally. The largest oil supply disruption on record added a fuel and fertilizer surcharge of up to 31% in some markets, with downstream impacts tracked in the June hunger hotspots report.
The split
The FAO headline index signals stability; grain-grower data from North America shows a divergent picture, US farmers face low farm-gate prices and weak exports even as the global index rises. Russia holds the structural supply balance: larger-than-expected Russian harvests are the primary ceiling on any price rally, and FOB prices slipping signals that geopolitical disruptions have not fundamentally changed Russian export volumes. Import-dependent populations in sub-Saharan Africa and South Asia, where food costs are a direct function of the global index, face a different reality than producers.
By the numbers
- 130.8, FAO Food Price Index, May 2026.
- +2.6%, Cereal Price Index month-on-month, May.
- +5%, Cereal Price Index year-on-year, May.
- +28%, US Hard Red Winter wheat vs May 2025.
- +31%, nitrogen fertilizer price increase (Hormuz spillover peak).
- 4, consecutive months of wheat price increases.
Why it matters
Rising cereal quotations raise import bills for grain-dependent populations, compounded by the fuel passthrough from the largest oil supply disruption on record and weather risk. The June FAO-WFP hunger hotspots report identified 318M people in crisis-level food insecurity (IPC 3+) across 13 hotspots, with fertilizer cost increases cited as a structural amplifier.
What to watch
- June FAO Food Price Index (due early July) for whether cereal prices hold post-Hormuz re-opening.
- Northern Hemisphere wheat harvest results, particularly US Hard Red Winter.
- Russian export volumes through the summer.
