Prices of sugar remained largely flat across markets barring north India, where prices inched up due to improved demand from north-eastern states. Most of the demand is coming from north-eastern states as markets in the western region were largely shut due to Raksha Bandhan festival and Lunar eclipse, which is considered inauspicious among traders. Government warning of re-imposing stock limits if prices rise further seems to have kept traders cautious and away from aggressive trade.
