New Delhi, Dec 21 : Oil marketing companies continued to hold back any change in retail price of petrol and diesel, continuing with their wait and watch stance that has kept the prices of two auto fuels static for the past couple of weeks. Accordingly, there was no change in retail price of auto fuels on Monday with price of petrol remaining at Rs 83.71 a litre and diesel Rs 73.87 a litre in Delhi. Across the country as well, the price of the two petroleum products remained unchanged. OMCs have gone on a pause mode at a time when news of successful coronavirus vaccine and expectations of big pick up in demand had kept crude on the boil with prices breaching $50 a barrel mark. Petrol price was very close to breaching the all time high level of Rs 84 a litre (reached on October 4, 2018) when it touched Rs 83.71 a litre on December 7. But the march has been halted ever since then with no price revision by the OMCs. Global crude prices have risen almost $12 a barrel in last one month to reaching over $50 a barrel now. But even at this level, it is far less than than average crude price of $80.08 a barrel in October 2018 when petrol prices reached highs of Rs 84 a litre in the Capital. With Monday's pause, fuel prices have now increased on 15 of the past 32 days with petrol prices rising by Rs 2.65 per litre and diesel by 3.41 a litre. Earlier, petrol prices had been static since September 22, and diesel rates had not changed since October 2. It started rising in November and again went for pause since December 8. Though retail pricing of petrol and diesel has been deregulated and oil marketing companies were following a daily price revision formula, the same was suspended for almost two months to prevent volatility in international oil markets from impacting fuel prices regularly during the pandemic. /IANS
