What Happened
- The central government reduced the Special Additional Excise Duty (SAED) on petrol and diesel by ₹10 per litre each, effective March 26, 2026.
- Simultaneously, it reimposed windfall tax (in the form of SAED) on exports of aviation turbine fuel (ATF) at ₹29.5 per litre and on diesel exports at ₹21.5 per litre.
- The windfall tax on fuel exports had been scrapped in December 2024 after nearly 30 months following a decline in global crude prices; it has now been reinstated due to the surge triggered by the US-Iran-Israel conflict.
- The CBIC (Central Board of Indirect Taxes and Customs) chief announced that the windfall tax on diesel and ATF exports will be reviewed on a fortnightly basis, consistent with the original 2022–2024 review mechanism.
- The export duty aims to discourage private refiners (Reliance, Nayara Energy) from preferring export markets over domestic supply when global prices are significantly higher.
- Revenue from the windfall tax on exports is estimated at approximately ₹1,500 crore per fortnight.
- Global crude oil prices climbed from ~$70/barrel pre-war to ~$122/barrel, creating large arbitrage incentives for refiners to export rather than supply the domestic market.

Windfall Tax: Concept and India's Experience
A windfall tax is a one-time or temporary levy imposed by governments on industries that experience unexpectedly large profits due to external circumstances — typically commodity price spikes caused by geopolitical events rather than the firm's own business decisions. India first introduced a windfall tax on July 1, 2022, in the form of Special Additional Excise Duty (SAED), following the Russia-Ukraine war, which caused global crude prices to surge above $100/barrel. Private refiners were exporting record volumes of petrol, diesel, and ATF instead of selling domestically, creating local shortages and inflating OMC losses. The tax was designed to redirect supply homeward and capture windfall profits for public revenue.
- First imposed: July 1, 2022; initial rate on crude oil: ₹23,250/tonne (~$283/tonne)
- Extended to diesel and ATF exports within weeks of introduction
- Review mechanism: fortnightly revision based on average crude prices of the preceding two weeks
- Revenue generated: ~₹25,000 crore (2022-23), ₹13,000 crore (2023-24), ₹6,000 crore (partial 2024-25)
- Scrapped: December 2, 2024 — when crude fell to ~$70/barrel and export arbitrage disappeared
- Reinstated: March 26, 2026 — when crude crossed $120/barrel again
Connection to this news: The reimposition follows the same logic as 2022: a sharp crude price spike driven by geopolitics creates large incentives for private refiners to export rather than supply domestic consumers, requiring the government to use SAED to redirect fuel domestically.
Special Additional Excise Duty (SAED) as a Fiscal Tool
SAED is a component of central excise levy that the government can adjust without parliamentary approval via an executive notification under the Central Excise Act, 1944. This flexibility makes it the government's preferred lever for rapid fiscal response to commodity price volatility. Unlike changes to basic excise duty or customs duty, SAED modifications can be notified and made effective within 24 hours, allowing immediate market response. This administrative flexibility is particularly valuable in energy markets where price signals must translate quickly into supply chain behaviour.
- SAED changes: notified via gazette notification, no parliamentary vote required
- Applicable to: domestically produced crude oil, petrol, diesel, ATF (both domestic sales and exports)
- Revenue from SAED: not shared with states (not part of the divisible pool)
- Review: typically fortnightly for volatile commodities; less frequent for stable ones
- Other uses of SAED: previously used for tobacco, pan masala, and other sin goods
Connection to this news: The government used SAED both to reduce the domestic fuel burden (cutting SAED on petrol/diesel sales) and to impose export restraint (levying SAED on ATF and diesel exports), demonstrating SAED's dual utility as both a demand-relief and supply-management tool.
India's Refinery Sector: Public vs. Private Dynamics
India's petroleum refining sector has two distinct segments: public sector OMCs (IOCL, BPCL, HPCL, MRPL, CPCL) operating about 18 refineries, and private sector giants — primarily Reliance Industries (Jamnagar, world's largest single-location refinery at ~1.24 million bbl/day) and Nayara Energy (Vadinar). Private refiners operate largely on export-oriented logic: they buy crude at market prices, refine, and sell to the highest bidder globally. During price spikes when international prices far exceed domestic regulated prices, private refiners naturally divert exports, reducing domestic availability. Windfall taxes and export duties are the government's primary regulatory tools to manage this dynamic.
- Reliance Jamnagar: ~1.24 million bbl/day capacity — world's largest refinery complex
- Nayara Energy (Vadinar): ~400,000 bbl/day; partially owned by Rosneft (Russia)
- India's total refining capacity: ~254 million metric tonnes per annum (MMTPA) as of 2024
- OMC refineries: ~18 refineries, primarily supply domestic retail network
- Private refiners: ~30–35% of India's total refining capacity
Connection to this news: The windfall tax on diesel and ATF exports specifically targets private refiners (Reliance, Nayara) who face strong incentives to export at the current $120+/barrel crude price, ensuring domestic supply is not compromised for profit maximisation.
