Centre Scraps Petrol Export Duty, Hikes Diesel & ATF Levies: Oil Stocks in Focus

The Union government has scrapped the additional excise duty of Rs 2.50 per litre on petrol exports while simultaneously increasing the export levy on diesel by Rs 3 per litre and raising the duty on aviation turbine fuel (ATF) exports, according to an NDTV Profit report. The revised rates take effect immediately and mark a targeted shift in the Centre's windfall-tax framework that has governed fuel exports since July 2022. The decision directly impacts the gross refining margins (GRMs) of index heavyweights Reliance Industries, Indian Oil Corporation, Bharat Petroleum and Hindustan Petroleum — collectively accounting for over 10% of Nifty 50 weight — and sets the tone for the oil marketing companies' (OMCs) Q2 earnings trajectory.

What Happened

According to the NDTV Profit report, the Centre has eliminated the Rs 2.50 per litre special additional excise duty (SAED) on petrol exports that had been in place as part of the fortnightly windfall-tax review cycle. At the same time, the export duty on diesel has been raised by Rs 3 per litre, and ATF exports will attract a higher levy. The notification does not alter the domestic excise structure on petrol and diesel sold within India. The changes were announced via a gazette notification late Friday and are effective from Saturday, October 31, 2026. The report states that the revision follows the scheduled fortnightly review by the revenue department, which tracks international crack spreads and crude prices to calibrate the windfall levy.

Why It Matters for India

The windfall tax, introduced in July 2022, was designed to capture a portion of the extraordinary profits refiners earned from exporting fuel at globally elevated crack spreads while domestic retail prices were kept stable. The removal of the petrol export duty signals that petrol cracks have softened sufficiently to no longer warrant the levy, while the increase on diesel and ATF suggests those cracks remain elevated. For India, a net importer of crude but a net exporter of refined products, the calibration of export duties influences both the trade balance and the profitability of the downstream sector. The move also has fiscal implications: lower petrol export duty reduces revenue collections, but higher diesel and ATF levies may offset part of that loss. For OMCs, which have been marketing fuel at below-cost prices for extended periods, any improvement in export realisations supports overall profitability and reduces the need for budgetary support.

Market Impact

Nifty 50 & Sensex

Reliance Industries (weight ~11.5% in Nifty 50) and the three public sector OMCs — IOC, BPCL, HPCL (combined weight ~2.8%) — are the primary beneficiaries or affected parties. The Nifty Energy index, which tracks the sector, could see intraday volatility when trading resumes on Monday, November 2. The Nifty 50 itself, trading around the 23,450 resistance zone per the Economic Times technical note, may derive marginal support if oil stocks rally, though broader market direction will remain tied to global cues and the upcoming US Fed meeting.

Bank Nifty

No direct impact on Bank Nifty constituents, but improved OMC cash flows could marginally reduce credit risk for lenders with large exposure to the sector.

Sectoral Impact

Oil & Gas / Refining: Positive for Reliance (large exporter of petrol/diesel) as the petrol duty removal boosts realisations on gasoline exports. For PSU OMCs, the net effect depends on their product export mix; typically, diesel exports dominate, so the Rs 3/litre hike could compress diesel export margins, partially offsetting the petrol gain. Downstream Marketing: Improved export parity may allow OMCs to reduce under-recoveries on domestic sales, a key monitorable for Q2 results. Chemicals & Petrochemicals: Indirectly positive if naphtha and other feedstock economics improve alongside refining margins.

Historical Context

The windfall tax has been revised fortnightly since its inception on July 1, 2022. In the first year, the SAED on diesel peaked at Rs 13/litre and on ATF at Rs 6/litre, while petrol saw a Rs 6/litre levy that was later zeroed out in April 2023 before being reintroduced at lower levels. Each revision has triggered sharp intraday moves in oil stocks; for instance, the October 2023 removal of the diesel SAED led to a 4-6% single-day surge in OMC shares. The current adjustment — zeroing petrol while hiking diesel/ATF — mirrors the pattern seen in mid-2023 when gasoline cracks collapsed but middle-distillate cracks stayed strong. Historically, the market has rewarded clarity and stability in the tax regime over the absolute level, so a predictable fortnightly cadence is viewed favourably.

What to Watch

• Fortnightly review cycle: Next review due around November 15, 2026; track international crack spreads (Singapore GRM, petrol/diesel/ATF cracks) for directional cues.
• Q2 FY27 earnings of OMCs: IOC, BPCL, HPCL and Reliance report in early November; management commentary on export volumes, realised margins and domestic under-recoveries will be critical.
• Crude oil trajectory: Brent crude near $75/bbl keeps input costs manageable; any spike above $85 could trigger fresh windfall hikes.
• Domestic retail pricing: Watch for any pass-through of improved export parity to pump prices ahead of state elections.
• FII flows in energy: Foreign portfolio investors have been net sellers in Indian equities; a favourable duty regime could attract sector-specific inflows.
