The Oil companies have ruled out any immediate roll back in the prices of petrol. Briefing the media in New Delhi, IOC chairman Shri R.S. Butola said that the decision to hike the prices by 6.28 Rupees was taken after all the existing options were exhausted and it was done as a last measure in a collective manner. He, however, gave enough hints that if the international crude price softens and the Dollar-Rupee exchange rate eases, the hike may be partially rolled back on 1st of June, when the companies review the prices in a cyclic mode.Oil Companies revises petrol prices on 1st and 16th of every month on the basis of average international price and exchange rate in the previous fortnight. Shri Butola said, they are hoping that international oil prices will come down and if it happens, they will pass on the benefit to the consumers as was done on November 16 and December 1 after the November 4 petrol price hike last year. He said that in the last 50 days, the Oil companies had lost more than Rs.2400 crore and the under-recovery in the last year was Rs.4,890 crore.
