New Delhi: The big story this week was a cut in fuel prices. With election season closing-in, the government took a populist measure on Wednesday. It slashed prices of petrol by Rs5 per litre, diesel by Rs2 per litre and cooking gas by Rs25 per cylinder. This mini-booster is expected to stimulate growth, help the auto industry and tame inflation. But on the flip side, the margins that oil companies get from selling every litre of petrol comes down to Rs2 and for diesel less than Rs1. Under recovery or—the difference between the selling price and the cost—for a cylinder of LPG goes up from Rs32 to Rs57.
