Wheat prices were unchanged in Delhi markets amid thin trade. In Delhi, mill-quality wheat was sold at 1,740-1,750 rupees per 100 kg. Demand for the grain has declined as buyers are cautious and do not want to hold inventories ahead of the goods and services tax regime. The July contract on the NCDEX was trading at 1,628 rupees per 100 kg, up 0.5% from the previous close.
