OMC Margin Recovery Faces Debt and Tax Hurdles

Composite margins on petrol and diesel at India's state-run oil marketing companies have climbed back above levels seen before the recent West Asia conflict, according to a JP Morgan report. The improvement comes from lower crude oil prices and a government cut in excise duties.

The government slashed excise duty by ₹10 per litre in March, letting a larger share of retail fuel prices flow to the OMCs. JP Morgan estimates the excise reduction has cost the government roughly ₹1.8 lakh crore annually in forgone revenue. Without that cut, standalone fuel marketing margins remain below historical averages.

Refining margins have stayed elevated, helping the composite. The combined refining and marketing economics are stronger, even as standalone marketing margins are below average.

Two issues limit the upside, JP Morgan said. First, the OMCs have accumulated material debt over the past year while absorbing losses on petrol and diesel sales. Losses on LPG were also significant. That debt overhang weighs on valuations. Second, the excise cut may not last. The government could restore duties once global oil prices stabilise, especially given higher expenditure commitments over the next two fiscal years.

First-quarter earnings for the current fiscal year will likely be hurt by large inventory losses from the recent decline in crude prices, the brokerage added. Crude bought at higher prices in previous months is now being sold at lower prices, creating a one-time hit. From the second quarter onward, profitability should improve if crude stays below $80 a barrel and refining margins hold.

Losses on LPG are still elevated. They should start to track oil down soon, JP Morgan said, providing another leg of relief.

Among the three state-run OMCs, JP Morgan said BPCL and Indian Oil Corporation are expected to benefit most in the near term if crude continues to ease. HPCL's margins have also returned to or exceeded pre-conflict levels. The brokerage sees BPCL and IOC as the preferred bets in the current environment.

JP Morgan expects strong earnings in the December and March quarters if crude remains subdued. Visibility on fuel marketing margins beyond fiscal 2028 is limited. The sector remains a tactical play tied closely to crude oil movements and government tax policy.
