India cuts excise duties on petrol, diesel as global oil prices surge

India has slashed excise duties on petrol and diesel to protect consumers ​and curb a potential spike in inflation, while imposing windfall taxes on aviation fuel and diesel exports, amid volatile global oil markets due to ‌the Iran war. Global oil prices have surged past $100 per barrel after the near closure of the Strait of Hormuz, which serves as a conduit for 40% of India's crude oil imports, since the United States and Israel first struck Iran on February 28. In a government order late on Thursday, India's finance ministry reduced the special excise duty on petrol to three rupees ($0.0318) per litre from 13 rupees. It also cut the ​duty on diesel to zero from 10 rupees per litre.

India will lose 70 billion rupees ($739 million) a fortnight from the excise cuts, although it will recover ⁠part of this —15 billion rupees — through separate export taxes on some fuel products, Vivek Chaturvedi, chairman of the Central Board of Indirect Taxes and Customs, told a press ​briefing. The net hit to government finances will be 55 billion rupees per fortnight. The yield on 10-year government bonds rose seven basis points to 6.95%, its highest level in 20 months, ​on concerns that the government may struggle to meet its fiscal deficit target of 4.3% of GDP for the financial year beginning April. The tax cuts also ease the burden for oil marketing companies. While fuel prices in India are technically deregulated, state-run oil companies, which control 90% of the retail network, do not always raise prices when crude climbs. As a result, consumers are shielded from volatility, with ​either the government or the companies absorbing the increases. "Government has taken a huge hit on its taxation revenues to ensure very high losses of oil companies, approximately 24 rupees ​a litre for petrol and 30 rupees a litre for diesel, at this time of sky-high international prices, are reduced," Oil Minister Hardeep Singh Puri said in a post on X. International crude prices have gone through the roof in the last 1 month from around 70 dollars/barrel to around 122 dollars/barrel. Consequently, petrol and diesel prices for consumers have gone up all over the world. Prices have increased by around 30%-50% in South East Asian… — Hardeep Singh Puri (@HardeepSPuri) March 27, 2026 The ‌government said ⁠that at current crude rates, the combined daily under-recoveries being absorbed by oil firms stood at 24 billion rupees. Shares of oil marketing companies such as Bharat Petroleum Corp and HPCL reversed early gains to close slightly higher. Windfall tax on exports The diesel export tax was set at 21.5 rupees a litre, along with a 29.5 rupees a litre tax on aviation fuel exports, the order said. Between April 2025 and January 2026, India exported 14 million metric tonnes of gasoline and 23.6 million tonnes of gasoil. Most refiners have stopped exporting fuels. ​Reliance Industries is the country's biggest fuel exporter. Finance ​Minister Nirmala Sitharaman said the government ⁠would ensure there was no shortage of petrol, diesel and jet fuel. It would support oil marketing companies so that citizens were spared price hikes and ensure that jet fuel prices did not rise, she told news agency ANI. India, the world's third-biggest oil importer and ​consumer, relies heavily on overseas supplies. Also Read: What does each side in the Iran war say it would accept for a deal? In a letter dated Thursday, the petroleum ministry said it would raise the allocation of liquefied ​petroleum gas to commercial ⁠and industrial users by 20%, taking total supply to 70% of pre-crisis levels. The increase builds on an existing 50% allocation, with priority to sectors such as steel, automobiles, textiles and other essential industries. India had cut gas allocation for non-cooking purposes after the start of the Iran war. India consumed 33.15 million tonnes of cooking gas last year, with imports covering about 60% ⁠of demand. About ​90% of those imports came from the Middle East. Prime Minister Narendra Modi and his government have stressed that adequate ​arrangements were in place, including for fertiliser supplies for the summer sowing season and coal to meet rising electricity demand. The government, in a separate statement, assured the public that retail petrol and diesel prices would not ​change.
