The price of petrol was today hiked by Rs 2.21 per litre and that of diesel by Rs 1.79 at Delhi excluding local levies.
The price revision was to come into effect yesterday, but was deferred possibly to save the demonetisation-battered government from any blushes in Parliament.
The revised rates will be effective from midnight tonight.
This increase excludes local levies. The actual hike after considering VAT would be Rs 2.84 per litre in Delhi for petrol and Rs 2.11 for diesel.
After the hike, petrol in Delhi will cost Rs 68.94 per litre from midnight tonight as against Rs 66.10 currently, said Indian Oil Corp, the nation's largest fuel retailer.
Similarly, a litre of diesel will cost Rs 56.68 as compared to Rs 54.57 now.
IOC, Bharat Petroleum Corp (BPCL) and Hindustan Petroleum Corp (HPCL) revise rates on 1st and 16th of every month based on average international price in the previous fortnight.
But an increase that was warranted because of a rise in international gasoline (petrol) price to USD 62.82 per barrel from USD 57.43 and that of diesel to USD 60.97 from USD 56.79 was not announced yesterday.
Industry sources said the deferment was because Parliament was in session and any hike would have added to the discomfort of the government, particularly when it is facing heat over hardships caused by currency demonetisation.
The Winter Session of Parliament ended this afternoon. Rates were last revised on December 1 when petrol price was hiked by a marginal 13 paise a litre, but diesel rates were cut by 12 paise.
Prior to the December 1 price change, rates were hiked by Rs 1.46 a litre in the case of petrol and Rs 1.53 per litre for diesel, excluding local levies, on November 16.
"The current level of international product prices of petrol and diesel and Rupee-US Dollar exchange rate warrant increase in selling price of petrol and diesel, the impact of which is being passed on to the consumers with this price revision," IOC said in a statement.
It said the movement of prices in the international oil market and foreign exchange rate shall continue to be monitored closely and developing trends of the market will be reflected in future price changes.
