Finance secretary Arvind Mayaram said on Thursday the government expected diesel prices to become market-linked soon, helped by a softening of global crude oil prices.
“The decision of the government which stands today is reduction in diesel subsidy by 50 paise per month which means increase in prices by 50 paise. So, the logical conclusion is that as and when that is over, it will become market driven,” Mayaram said at an event organised by industry body Assocham.
