The profitability of both HPCL and BPCL was hit as they kept petrol and diesel prices unchanged despite global crude prices surging more than 70% at the peak of the US-Iran conflict.The OMCs subsequently raised petrol and diesel prices by nearly Rs 7.5 a litre and the price of a 14.2-kg domestic LPG cylinder by Rs 89 in the second half of May, but the increases were insufficient to offset the sharply higher input costs.While HPCL’s revenue from operations rose 21% to Rs 1.5 lakh crore from Rs 1.2 lakh crore a year earlier, BPCL’s revenue increased to Rs 1.6 lakh crore from Rs 1.3 lakh crore in the year-ago period. In a statement, HPCL said its performance reflected the impact of the ongoing West Asia crisis even as its refining and marketing operations remained resilient.
