New Delhi, Jun 28: Every time India has faced a major crisis - whether devastating floods, a once-in-a-century pandemic or the latest conflict in West Asia that threatened global oil supplies - it has been the country's state-run oil companies that have quietly kept fuel flowing. For decades, India's public sector oil marketing companies (OMCs) have often been criticised for low returns, government intervention in fuel pricing and bloated operations. They have twice been put on the block for privatisation, with plans to sell Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corporation Ltd (HPCL) gathering momentum in 2002 before being halted by a Supreme Court ruling and again in 2020, before the process was abandoned after failing to attract enough bids.
