What Happened
- The central government imposed a fresh export duty of ₹21.5 per litre on diesel and ₹29.5 per litre on aviation turbine fuel (ATF), reinstating a mechanism first deployed in July 2022 after it was withdrawn in December 2024.
- The move is a direct response to the near-closure of the Strait of Hormuz since February 28, 2026 — following US-Israeli strikes on Iran — which has pushed crude oil above $100/barrel and created a situation where Indian refiners could profit by selling domestically-processed fuel abroad at elevated international prices rather than supplying the domestic market.
- India faces acute shortages of LPG (used for cooking under the Pradhan Mantri Ujjwala Yojana scheme) and LNG (for industrial use) as the Gulf supply routes are disrupted; the export levy is designed to retain refined fuel within India.
- Exports to four neighbouring countries — Nepal, Bhutan, Bangladesh, Sri Lanka — remain exempt from the windfall tax for diplomatic and humanitarian reasons; these are handled by PSU-to-PSU transfers.

Windfall Tax on Fuel Exports: India's Policy Innovation
India was among the first countries globally to impose a formal windfall tax on petroleum product exports in July 2022. The levy targets the "windfall profit" that arises when international refining margins spike — enabling refiners to earn extraordinary returns by exporting at high global prices while having procured domestic crude at subsidised or government-mandated rates. The Special Additional Excise Duty on Exports (SAED-Exports) is reviewed every two weeks by a committee of the Finance and Petroleum Ministries based on the "crack spread" (difference between crude input cost and refined product price). The levy applies to private refiners such as Reliance Industries and Nayara Energy that have significant export capacity.
- First imposed: July 1, 2022 (India was among world's first to levy a windfall tax on fuel exports)
- Withdrawn: December 2024 (as global crude prices and crack spreads normalised)
- Reimposed: March 27, 2026 (following Hormuz-driven crude price spike above $100/barrel)
- Review cycle: Fortnightly (every 15 days) based on crack spread assessment
- Applicable to: Diesel, ATF, and petrol (petrol currently at nil rate as domestic demand is prioritised)
Connection to this news: The reimposition signals that the government is applying the same logic as 2022 — prevent the domestic supply squeeze from worsening while private refiners arbitrage the global price spike. The simultaneous domestic excise cut and export windfall tax is a classic twin-lever fuel policy.
LPG Supply Chain and India's Energy Security Vulnerabilities
LPG (Liquefied Petroleum Gas), primarily a mix of propane and butane, is a key cooking fuel for approximately 320 million households in India covered under the Pradhan Mantri Ujjwala Yojana (PMUY). India meets 55–60% of its LPG demand through imports, predominantly from Saudi Arabia (via Aramco) and the UAE. The Strait of Hormuz disruption has severed this supply chain, creating acute LPG shortages — particularly in rural areas where no alternative cooking fuel infrastructure exists. The government has invoked emergency procurement protocols and is exploring spot cargo purchases from the US (Gulf Coast LPG) and Australia.
- India is the world's second-largest LPG importer (after China)
- ~55–60% of LPG demand met through imports; Saudi Arabia and UAE are top suppliers
- PMUY (launched 2016): covers ~100 million BPL households with subsidised LPG connections
- India's LPG import terminals: Kandla, Haldia, Mangaluru, Vizag (principal terminals)
- Hormuz closure = direct disruption to Saudi and UAE LPG cargoes to India
Connection to this news: The LPG shortage is the most acute consumer-facing consequence of the Hormuz closure; it underpins the urgency of the government's dual policy of cutting domestic excise on petrol/diesel while slapping export duties to prevent further domestic fuel diversion.
India as the Third-Largest Oil Consumer: Strategic Implications
India is the world's third-largest oil consumer (after the United States and China), consuming approximately 230 million metric tonnes per year. About 85% of this is imported, primarily from the Middle East (historically ~65% of imports from the Gulf region). The concentration of supply from a single geographically proximate region has long been identified as a strategic vulnerability. Diversification efforts include increased Russian crude purchases (2022 onwards), long-term deals with the US, Nigeria, and Brazil, and investments in Iranian oil fields (Farzad-B) — the last of which have been complicated by US sanctions.
- India's crude oil import (2024-25): ~232 million tonnes/year
- Import dependency: ~85% of total consumption
- Gulf share of crude imports (pre-2022): ~65%; post-2022 (with Russia surge): ~45%
- Russia's share as of early 2026: ~35-40%
- India's strategic petroleum reserves: ~5.33 million metric tonnes (at Visakhapatnam, Mangalore, Padur) — covers approximately 9.5 days of net imports
Connection to this news: India's precarious oil import dependency — and the inadequacy of its strategic petroleum reserves for an extended Hormuz disruption — makes the windfall tax and excise cut a short-term stabilisation measure rather than a structural solution.
