Prices of most food items are expected to be stable this festive season due to ample stocks and good global supply situation while sugar prices are likely to remain firm in the month ahead, trade insiders said. Onions and tomatoes have become cheaper in recent weeks after these two commodities, along with fuel, pushed the country’s wholesale price inflation to a four-month high of 3.24% last month. Prices of cereals, which have highest weightage in the Consumer Price Index, are also expected to remain fairly stable, trade analysts said.
