New Delhi: State-owned fuel retailers are losing close to Rs 3 per litre on selling diesel while the profit on petrol has trimmed due to recent firming up in international oil prices, industry officials said detailing reasons for continuing to hold retail prices.

Indian Oil Corporation (IOC), Bharat Petroleum Corporation Ltd (BPCL) and Hindustan Petroleum Corporation Ltd (HPCL), who control roughly 90 percent of India's fuel market, 'voluntarily' have not changed petrol, diesel and cooking gas (LPG) prices for almost two years now, resulting in losses when input cost was higher and profits when raw material prices were lower.

International oil prices, against which domestic rates are benchmarked as India is 85 percent dependent on imports to meet its oil needs, had softened late last year but firmed up again in the second half of January.

They have resisted calls to revert to daily price revision and pass on softening in rates to consumers on grounds that prices continue to be extremely volatile - rising on one day and falling on the other - and that their past losses haven't been fully recouped.
