State-owned fuel retailers—Indian Oil Corporation, Bharat Petroleum Corporation, and Hindustan Petroleum Corporation—are bleeding. As Brent crude surged past $100 per barrel in September 2026, marketing margins turned deeply negative.
The primary driver is the sharp escalation in international crude costs, fueled by renewed US-Iran tensions and supply disruptions around the Strait of Hormuz, which have pushed the Indian crude basket average to $108.91 per barrel on September 8, up from $82.04 in July.
Retail petrol and diesel prices have remained frozen for over three months, last revised on May 25. This administrative decision means retailers cannot pass on higher international costs to consumers. In May, prices were raised cumulatively by Rs 7.35 per litre for petrol and Rs 7.53 for diesel across four instalments. However, these increases were partial and insufficient to align retail prices with the subsequent surge in crude. The result is a widening gap between cost and realization, forcing Oil Marketing Companies (OMCs) to absorb the entire burden. With the Indian crude basket averaging $102.11 for September so far, the under-recoveries have intensified significantly compared to the post-May period.
Domestic LPG under-recoveries stand at Rs 200 per cylinder. This is driven by high international LPG prices, linked to benchmarks like Saudi CP, and a government policy to insulate consumers from volatility. Despite international prices remaining elevated, the increase has not been passed on to households. To manage this fiscal strain, the government approved Rs 30,000 crore in compensation to OMCs in August 2025, paid in tranches, to help them meet critical procurement and debt servicing needs. However, as crude prices climb anew, the burden on LPG margins returns, adding to the overall financial stress on state retailers.
India imports over 88% of its crude oil, making the economy acutely sensitive to Brent price movements. This dependence creates a vicious cycle: higher crude prices increase the dollar demand for imports, which weakens the rupee. A weaker rupee then raises the domestic cost of every dollar of oil imported, amplifying the initial shock. The rupee has depreciated significantly, trading near record lows, which further inflates the landed cost of crude in rupee terms. Every $10 per barrel increase in crude adds roughly $2 billion to India's annual import bill, widening the trade deficit and putting pressure on the current account deficit (CAD) and foreign exchange reserves.
Crucially, this spike was almost entirely price-driven.
The average landed price of imported crude jumped from approximately $68 per barrel to $106 per barrel. This pure price effect reflects the severe terms-of-trade shock India faces, where it pays significantly more for roughly the same volume of energy, straining the external sector and fiscal buffers.
Higher crude prices transmit inflation across the economy through multiple channels. Aviation, where fuel accounts for nearly 40% of operating costs, faces immediate margin pressure. Paints and tyres rely on crude-derived inputs like solvents and carbon black, which constitute up to 40-50% of raw material costs. Chemicals and petrochemicals use naphtha and other feedstocks directly linked to crude. Logistics and transportation see diesel costs rise, affecting the movement of virtually all goods. FMCG companies face higher packaging costs for polymers. The speed and extent of cost pass-through depend on market structure, demand elasticity, and competitive intensity. Sectors like logistics may pass through costs faster (1-2 months) due to fuel escalation clauses, while FMCG may take 6-12 months due to consumer resistance.
The sustained rise in Brent above $100 poses a significant inflation risk. The transmission works through direct fuel prices, cost-push in supply chains, and the exchange rate channel. While the RBI has kept the repo rate unchanged at 5.25% with a neutral stance, a tightening bias cannot be ruled out if elevated crude feeds into broader inflation.
The RBI's own projections for FY27 headline CPI at 5.1% already incorporate upside risks from global commodity shocks.
Brent's push above $100 is driven primarily by US-Iran tensions and supply concerns around the Strait of Hormuz, a critical chokepoint for global oil trade. Disruptions here threaten supply, creating a risk premium. OPEC+ has responded by holding output steady for October, reaffirming its commitment to market stability amid uncertainty. This decision, coupled with the group's stated flexibility to adjust production, sustains firm and volatile prices. For Indian OMCs, this means continued high procurement costs and sustained under-recoveries, as the supply side remains tight while retail prices are frozen.
The easing of geopolitical tensions could significantly alter cost dynamics. A de-escalation in West Asia or a stabilization of the Strait of Hormuz could reduce the risk premium, potentially pulling Brent back towards the $90 range. This would lower the landed cost of crude, reduce under-recoveries, and ease pressure on the rupee and CAD. However, the timeline for such normalization is uncertain. Until then, state-owned fuel retailers must navigate a period of severe financial stress, relying on government compensation and fiscal support to maintain operations while the broader economy absorbs the inflationary impact of expensive energy.
