New Delhi, May 30 -- State-run oil companies are facing a daily loss of Rs.550 crore on petroleum sales, including petrol and diesel, the government on Friday said even as international oil prices fell sharply to nearly $92 a barrel, a 23% decline from the post-war peak of $120 on March 9. Speaking at the inter-ministerial briefing, petroleum ministry's joint secretary Sujata Sharma said, "I don't have the breakup of Rs.550 crore company wise." State-run Indian Oil Corporation (IOC), Bharat Petroleum Corporation Ltd (BPCL) and Hindustan Petroleum Corporation Ltd (HPCL) controls over 90% of India's fuel retail market. She did not disclose the breakup of current under-recoveries suffered by public sector oil marketing companies (OMCs) on individual products such as petrol, diesel, cooking gas (liquefied petroleum gas or LPG), and aviation turbine fuel (ATF) sold to domestic airlines. Sharma's statement that OMCs are still losing Rs.550 crore revenue every day, indicates another hike in auto fuel rates as well as other petroleum products soon, sector experts said requesting anonymity. "It appears that OMCs are recovering their losses on all products like LPG and ATF by raising prices of petrol and diesel. It would have been ideal that their pricing policy should be more transparent," one of them said. So far, OMCs have raised petrol prices by Rs.7.35 per litre and diesel prices by Rs.7.53 a litre since May 15. The last price revision was on May 25. According to officials, OMCs were losing Rs.1,000 crore daily (before first price hike on May 15)....
