ONGC jumps as 2026 royalty cuts lift oil-gas outlook

What changed and why it mattered to markets

Oil and gas shares moved sharply higher after the Indian government notified revisions to royalty rates and calculation methodologies for crude oil and natural gas production. The changes were positioned as a move to improve the economics of upstream production, encourage fresh exploration, and support India’s push to reduce import dependence. Royalty is a levy paid by producers such as Oil and Natural Gas Corporation (ONGC) and Oil India to the government for extracting crude oil and natural gas from the country’s reserves. It is typically calculated as a percentage of the market value of extracted oil or gas.

The market treated the announcement as immediate policy relief for upstream companies, where fiscal terms and regulatory decisions can materially affect cash flows. Brokerage CLSA described the royalty cuts as a “significant positive” for ONGC and Oil India, especially at a time when elevated global crude prices had kept concerns around potential windfall-style levies in focus.

Stock reaction: ONGC and Oil India lead the rally

In trading on May 12, 2026, upstream stocks outperformed in an otherwise weak market. ONGC rallied 6% to Rs 298.95 on the BSE, while Oil India surged 8.58% to Rs 495.70. Other reports from the same session also noted ONGC rising to around Rs 295.50 intraday, and Oil India to around Rs 490.85, reflecting strong early buying interest.

Oil India jumped approximately 7% and ONGC rose over 4% at points during the session, with ONGC featuring among the top Nifty gainers. Vedanta, which has onshore operations through Cairn Oil & Gas, was also in focus after the policy update. The sharp move in upstream counters stood out against broader weakness, with the BSE Sensex down about 0.90% during the session.

The key royalty cuts: crude oil and natural gas

The government reduced effective royalties across major producing categories, with the biggest relief highlighted for legacy onshore crude output. Under the revised framework referenced by CLSA, the effective royalty rate on onshore crude production declines from 16.66% to 10%. Offshore crude royalty reduces from 9.09% to 8%. Royalty on natural gas also comes down to around 8% from 10%.

In parallel, separate details in the notification-based reporting highlighted that for nominated blocks and pre-NELP production sharing contracts, the onshore crude royalty rate has been cut from 20% to 12.5% on an ad valorem basis calculated on the well-head price. For natural gas, the headline NWG rate was described as reduced from 10% to 9%, while the effective rate falls further to approximately 8% due to the revised well-head price methodology.

Methodology overhaul: deductions and standardisation

Beyond rate cuts, the policy shift included changes to how royalty is computed. CLSA highlighted that the government revised the royalty structure for nomination blocks by introducing a standard ad-valorem deduction of 20% and applying a royalty rate of 12.5% for onshore blocks and 10% for offshore blocks. The brokerage said the change effectively implies a reduction of around 6.7 percentage points in royalty for onshore crude production and nearly 1 percentage point for offshore crude.

Other reporting on the notification said the government shifted to fixed deductions instead of actual post-well-head costs when calculating well-head prices. These include a 20% deduction of sale price for the nomination regime and 15% for others. The goal, as described, is to bring more uniformity across contractual and policy regimes and reduce longstanding inconsistencies.

Incentives for difficult fields: DSF and HELP blocks

The revised framework also introduced targeted incentives for challenging geographies under policies such as the Discovered Small Field Policy (DSF) and the Hydrocarbon Exploration and Licensing Policy (HELP). Ultra-deep-water production in such fields will attract zero royalty for the first seven years, 5% for the next phase, and 2% thereafter, according to CLSA. Separately, shallow-water offshore fields were described as typically attracting a 10% royalty rate.

The stated intent of these incentives is to lower operational costs for companies exploring difficult and high-investment fields. The policy package was framed as supportive of exploration, domestic production growth, and energy security.

What CLSA said: fair value impact for ONGC and Oil India

CLSA estimated that the royalty cut “could add fair value of 7%-9% for ONGC and 9%-11% for Oil India.” The brokerage also linked the move to market sentiment, noting that the surprise action to cut upstream taxes, rather than raise them, should help ease concerns around another round of windfall-style taxation.

While the near-term stock reaction reflected the policy change, the broader investor question remains how much of the benefit flows through to operating margins and free cash flow as royalty is a fiscal charge tied to production value.

Oil price backdrop: Brent above $100

The policy update came as global crude prices remained elevated. Brent crude, which was cited as trading close to $15 per barrel a few months earlier, was described as trading above $100 per barrel, with Brent crude futures priced at $105 per barrel on Tuesday, according to Trading Economics.

Higher crude prices can support upstream realisations, but they can also increase policy sensitivity around consumer inflation and government revenues. Against that context, the royalty reduction was interpreted as a supportive signal for domestic producers.

Key numbers at a glance

Why the royalty cut matters for India’s upstream sector

Royalties are paid ahead of profit-sharing and directly affect per-barrel and per-unit economics, so any reduction can improve project viability. The government framed the changes as part of modernising the regulatory framework following the 2025 amendments to the Oilfields (Regulation and Development) Act and the Petroleum and Natural Gas rules. Union minister Hardeep Singh Puri described the rationalisation as improving regulatory clarity and eliminating inconsistencies across regimes.

For investors, the key takeaway from the day’s trade was that policy risk is a major input for upstream valuations. The combination of lower effective royalties, standardised methodology, and added incentives for difficult fields was treated as a positive signal for domestic exploration and production.

Conclusion

ONGC and Oil India rallied sharply on May 12, 2026, after the government cut effective royalties on onshore and offshore crude oil and natural gas and updated the calculation framework. CLSA said the move could add 7%-9% fair value for ONGC and 9%-11% for Oil India. The next market focus will be on how the revised structure is implemented across regimes, including nomination blocks, pre-NELP contracts, and HELP and DSF areas where deep-water incentives apply.
