• India raised diesel prices by 2.9% to Rs 95.20/liter in Delhi on May 25, the fourth hike in ten days
• Cumulative diesel increase since May 15 stands at 8.6%, the highest prices since May 2022
• Iran war disruption of Strait of Hormuz and a weaker rupee drove the four-year pricing freeze to break
• Indian Oil, Bharat Petroleum, and Hindustan Petroleum together control 90% of India's retail fuel market
• Survey shows 50% of Indian consumers already experiencing higher transport and service costs

India's three state-run oil marketing companies raised retail diesel and gasoline prices for the fourth time in less than ten days on May 25, 2026, marking the most aggressive series of fuel price revisions in the country in four years. Diesel in New Delhi was raised by 2.9% to Rs 95.20 per liter, while gasoline prices were increased by 2.6% to Rs 102.12 per liter, according to company statements from Indian Oil Corporation, Bharat Petroleum Corporation, and Hindustan Petroleum Corporation, which together control approximately 90% of India's fuel retail network.

The cumulative impact since the first hike on May 15 amounts to increases of 8.6% for diesel and 7.8% for gasoline. Prices are now at the highest level since May 2022. The first revision on May 15 was the first upward adjustment in nearly four years, as the Modi government had effectively held pump prices steady for an extended period despite rising import costs. With Brent crude prices having risen approximately 50% since the Iran conflict began in early 2026, state refiners had been absorbing widening losses that became increasingly unsustainable.

The Iran war has kept the Strait of Hormuz under severe disruption, through which a significant share of global oil trade passes. With roughly 85% of India's crude oil requirements sourced through imports, the combination of higher crude benchmarks and a weaker rupee against the dollar compounded refinery margin losses significantly. Agricultural harvest season demand and growing pricing disparities between state-owned and non-state fuel retailers added to the pressure to resume revisions.

A survey by LocalCircles conducted in the days following the hikes found that approximately five in ten consumers in India reported higher transportation and service costs and planned to reduce discretionary travel. For procurement managers across manufacturing, agriculture, food processing, and logistics sectors operating in India, the hikes translate directly to higher transport, distribution, and production costs that will take weeks to fully ripple through supply chain pricing.

On May 23, a prior revision had raised diesel by Rs 0.91 per liter and petrol by Rs 0.87 per liter. The May 25 revision added Rs 2.71 per liter to diesel and Rs 2.61 per liter to gasoline. Compressed natural gas prices in Delhi were also raised by Re 1 per kg to Rs 81.09 per kg as part of the same revision cycle. Market analysts have warned that unless international crude prices stabilize, further upward revisions cannot be ruled out in the near term.
