India has imposed a limit on the amount of wheat stocks traders can hold in an effort to bring down prices, food secretary Sanjeev Chopra told reporters on Monday. The world's second biggest wheat producer will also provide 1.5 million tonnes of wheat to bulk consumers such as flour millers, as part of efforts to bring down prices, which have risen 8% in a month, Chopra said. "Unscrupulous elements are hoarding wheat stocks and that's why prices are rising," he said.
