The FAO Food Price Index fell for the third month in a row in November, declining by 1.2 percent. Prices declined for all commodities except cereals. The Index in November stood 2.1 percent below its year-earlier level and nearly 22 percent below the peak of March 2022.

The FAO Food Price Index fell 1.6 percent in October, driven by lower cereals, dairy, meat, and sugar prices. The October Index was 21 percent below its March 2022 peak.
