World food prices rise 1.5% to 136.0 in September; cereals jump 5.1% and vegetable oils run 18% above a year ago

World food commodity prices rose again in September. The United Nations Food and Agriculture Organization said on Friday that its Food Price Index averaged 136.0 points, up 2.0 points or 1.5% from August and 5.8% higher than a year earlier. Cereals, vegetable oils and sugar all rose. Meat fell and dairy was flat.

The index tracks export prices for traded commodities, not what a shopper pays at a US supermarket. It is still the earliest read on the raw ingredients that end up on a supplier's invoice a few months later.

The number behind the headline: it is a crop story, not a food story

The headline figure averages five groups, and in September they went in different directions. The FAO's own sub-indices make the split plain:

Inside cereals, the FAO said world wheat prices rose 6.3% in the month to their highest since August 2023, driven by logistics problems in the Black Sea region and dry weather in parts of North America before winter wheat planting. Maize (corn) rose 5.6% to its highest in more than three years, on lower than expected US yields, less export supply from Brazil, and worries about fuel, fertilizer and freight costs tied to shipping through the Strait of Hormuz. Sorghum jumped 13.7%.

The overall index is still 15.1% below its March 2022 peak. "Food prices near a four-year high" is accurate for the index; it is not accurate for every aisle. Dairy is heading the other way: the FAO said cheese prices fell across the major exporters, with abundant US export supply weighing on European prices, and butter was little changed. Skim milk powder was the exception, 33.1% above a year ago.

Who it actually hits

Fryer-heavy kitchens. Vegetable oils are the group furthest above last year, at 18.3%. The FAO credited palm oil, up for a fourth straight month, and firm soy oil demand from biofuel makers. For illustration only: a restaurant spending $1,000 a month on fryer oil would pay about $183 a month more if its supplier passed through the full year-over-year rise. Actual pass-through depends on the contract, and distributors often lag the export market by months.

Bakeries. Wheat at its highest since August 2023 matters most where flour is the main ingredient. CheckThisBiz lists 35,649 independent bakeries in the US; for most of them, flour is bought on short contracts and the September move will show up in the next price list rather than this one.

Pizzerias and anyone buying cheese. The 19.1% year-over-year drop in the dairy index is the one piece of relief in the release. A kitchen whose biggest line is cheese is seeing a different market from one whose biggest line is oil or flour.

Livestock feeders. Corn at a three-year high in the export market sits awkwardly next to the US picture. USDA counted 2.10 billion bushels of old-crop corn on September 1, up 35% from a year earlier, and December corn fell to $4.99 on that report. Ample US bins and a firm world price can coexist when the squeeze is in shipping lanes and other exporters, which is what the FAO describes.

605,380 independent restaurants are listed on CheckThisBiz, a directory of 7,704,724 independent US businesses, including 79,108 in CA, 54,058 in TX, 51,387 in NY. Chains and franchises are excluded from that count, so these are the owner-operated businesses that actually apply for funding.

Food service is the largest single industry in that directory, which is why ingredient indices like this one feed straight into the owners we write for. Our restaurant operating playbook covers menu pricing and supplier terms.

What to watch

The FAO publishes its next index on November 6. Before that, the USDA's monthly crop report and the course of Black Sea and Gulf shipping will decide whether September's cereal jump holds. The FAO noted that daily wheat quotes eased toward the end of the month, so part of the monthly average may already be behind the market.
