New Delhi, May 15, 2026 — Domestic petrol and diesel prices have seen a marginal increase, with Indian Oil Corporation Limited (IOCL) refineries reportedly operating above 100 percent capacity to forestall any shortages. IOCL Director Arvind Kumar characterized the price adjustment as a "very small rise," even as reports suggest that oil marketing companies (OMCs) were absorbing significant daily losses, estimated at around ₹1,000 crore, to maintain price stability.
The modest price hike comes as a direct consequence of escalating global pressures, primarily attributed to the ongoing conflict in West Asia involving the United States, Israel, and Iran. This international instability has created significant upward pressure on petroleum product costs, though the current domestic revision is understood to cover only a fraction of the actual increase in operational expenses for fuel suppliers.
The implications of this price adjustment are expected to ripple through the economy, potentially impacting various sectors reliant on fuel. Specific price points released indicate diesel now stands at ₹93.14 per litre in Mumbai (a rise of ₹3.11), ₹95.13 in Kolkata (up ₹3.11), and ₹95.25 in Chennai (up ₹2.86). Petrol prices in these metros have also seen increases, with Kolkata reaching ₹108.74 (up ₹3.29), Chennai at ₹103.67 (up ₹2.83), and Mumbai at ₹106.68 (up ₹3.14).

In response to the sustained global pressure on petroleum products, IOCL is also actively pursuing alternative energy solutions. This includes advancements in green hydrogen production at its Faridabad Research and Development centre, where hydrogen buses are being refueled. These initiatives, while currently presented as a "symbolic shift toward zero-emission public transport," signal a longer-term strategic direction for the corporation.
