World food prices rose in August to their highest ⁠since late 2022, as adverse weather ⁠and war disruption in the Black Sea heightened concern over the supply of staples, the United Nations' food agency said Friday.

Extreme heat and drought ​in Europe, the threat of a severe El Nino weather ​pattern ⁠and trade upheaval caused by the Ukraine and Iran wars have unsettled agricultural markets, pushing grain prices to three-year highs and sugar to a one-year peak.

The Food and Agriculture Organization (FAO) Food Price Index, which tracks monthly changes in a basket of internationally traded food commodities, averaged 133.3 points in August, up from July's revised reading of 130.8.

That was the highest score since November 2022, though nearly 17% below a record peak from March 2022, after Russia's full-scale invasion of Ukraine.

"August's increase in global food prices is a warning that the risk premium is returning to food markets: climate shocks, geopolitical tensions ⁠and ⁠disrupted trade logistics are converging to tighten supply expectations," FAO Chief Economist Maximo Torero said in a statement.
