Global prices for food commodities like rice and vegetable oil have risen for the first time in months after Russia pulled out of a wartime agreement allowing Ukraine to ship grain to the world, and India restricted some of its rice exports, the U.N. Food and Agriculture Organization said Friday.

The FAO Food Price Index, which tracks monthly changes in the international prices of commonly traded food commodities, increased 1.3% in July over June, driven by higher costs for rice and vegetable oil. It was the first uptick since April, when higher sugar prices bumped up the index slightly for the first time in a year.
