World food prices rose in July to their highest in more than three years as ​adverse weather and war escalation in the Gulf and Black Sea supported crop markets, the United Nations Food and ​Agriculture Organization (FAO) said on Friday.

The FAO Food Price Index, which tracks monthly changes in a basket of ​internationally traded food commodities, averaged 131.1 points ​in ⁠July, up from 130.3 in June and the highest reading since January 2023.

The world faces another bout of food inflation as wars in Iran and Ukraine, along with El Nino, create a perfect storm of higher costs and lower crop yields, the FAO's chief economist told Reuters this week.

A 3.4% month-over-month rise in the FAO's cereal price index drove the July trend, fueled ⁠in ⁠turn by a 5.8% jump in wheat prices, the agency said.

Wheat markets were affected by concerns over Black Sea export disruptions and heat damage to crops in key producing regions, it said.
