THE NONEXPERT a view, not a verdict.

ONGC Defies the Nifty Slide — But One Tax Clause Could Change Everything

The mood in Indian equities right now is somewhere between cautious and genuinely spooked. The NIFTY 50 has shed 12.4% in a single month — dropping from 25,807.2 on February 27 to 22,612.8 as of March 30, 2026, per Yahoo Finance — and the selling has been indiscriminate enough that most portfolio managers are spending their days explaining losses rather than hunting for opportunities. FII outflows, geopolitical stress in the Strait of Hormuz, a rupee that has slid sharply against the dollar — it all adds up to a market that wants to reduce exposure, not add it.

And then there’s ONGC, which has posted a firm gain over that same brutal month. That’s not a rounding error; it’s a double-digit percentage point gap against the index, in an environment where even the most defensive names have struggled to hold ground. The stock touched a three-month high in mid-March and has held most of that move even as the broader market continued to deteriorate. The distance traveled since its January low, in the middle of a market rout, deserves a proper explanation.

What Daman Actually Changes

The headline driver is the Daman Upside Development Project in the Arabian Sea. Gas production has commenced, and the market is treating it as a meaningful step-change in ONGC’s volume profile rather than an incremental update. That read is probably right. ONGC’s older producing fields have been a source of quiet anxiety for years — mature assets, declining curves, the kind of production trajectory that makes long-term models uncomfortable. Daman doesn’t solve that entirely, but it interrupts the narrative. It gives analysts something concrete to point to when they need to argue that the production outlook isn’t just a slow bleed.

Volume growth matters here in a way it wouldn’t in a quieter commodity environment. The Hormuz disruption, Brent pushing aggressively higher, the macro language around an “oil shock” — the price side of the equation is already working hard for upstream producers. When you layer new production on top of a strong price environment, the earnings leverage is significant. ONGC is an explorer and producer. Its revenues are denominated in or benchmarked to dollar-priced crude. The rupee weakening against the dollar, which is hurting import-heavy businesses and causing FII anxiety, is actually a tailwind for ONGC’s realized revenues in rupee terms. The macro stress that’s hammering the rest of the market is, in several dimensions, actively constructive for this company.

That’s the basic bull case, and it’s not complicated. High prices, new volumes, a currency move that helps rather than hurts, and a state-backed balance sheet that doesn’t require investors to worry about counterparty risk in a volatile environment. When capital gets defensive, it looks for exactly this combination — a cyclical commodity upswing layered onto a structural improvement in the company’s production profile.

The Variable Nobody Is Discussing Loudly Enough

Here’s where I’d slow down. The SAED — the Special Additional Excise Duty, sometimes called the windfall tax — operates on a fortnightly review cycle. When global crude prices spike, the Indian government has historically moved to recapture a portion of the upstream windfall through SAED adjustments. The mechanism is still active. The reviews are quiet, they don’t generate the kind of headlines that move stocks intraday, and they tend to get buried under the production news. But the effect on realized margins can be substantial.

The market right now is pricing in ONGC’s participation in the crude oil shock. The Daman production news gives that pricing a tangible anchor. What’s less priced in is that the government’s policy reflex — to smooth through the windfall via SAED — could meaningfully decouple ONGC’s actual earnings from where Brent is trading. This is a documented pattern. And in an environment where crude is moving as aggressively as it has been, the probability of an SAED revision isn’t low.

There’s a second constraint worth naming. Domestic gas prices in India operate under a ceiling structure. The Daman project is predominantly a gas asset. New gas volumes from Daman won’t price at international spot — they’ll price against a regulated ceiling that currently sits well below where global LNG markets are trading. So the revenue capture from the new production, while real and meaningful, is not the uncapped upside that the “crude oil shock” framing might imply. The weakest assumption in the current bull case is that Daman’s gas volumes will capture anything close to the Brent-linked premium the market seems to be attributing to them. Investors treating Daman as a pure beneficiary of the Hormuz spike need to make that distinction more carefully.

None of this changes the directional bull case. It complicates it. ONGC is still up strongly in a month where the NIFTY lost double digits. The outperformance is real, and the reasons behind it are legitimate. Daman is a genuine catalyst. The macro backdrop is genuinely favorable for an upstream producer. The defensive capital rotation into ONGC makes structural sense given what’s happening in banking and IT.

But the cleanest version of the bull case — the one where ONGC rides the full Hormuz premium all the way to earnings day — has a regulatory trapdoor underneath it. The SAED review schedule doesn’t care about investor positioning. The gas price ceiling doesn’t soften because Brent is high. These aren’t reasons to abandon the thesis. They’re reasons to hold it with some precision about what exactly you’re buying.

What the chart shows, looking at the normalized performance from January through March, is a stock that moved quietly in January and February while the market drifted, then accelerated in March as production news landed and the broader selloff created a contrast effect. That acceleration happened against a NIFTY in steep decline. That’s not sector rotation noise. That’s a stock doing something specific.

Whether ONGC continues from here depends on two things that aren’t fully in the company’s control: how aggressively the government moves on SAED in the next review cycle, and how long the Hormuz disruption sustains crude at current levels. Both are knowable in advance of earnings. Both are being underweighted in the current conversation about why ONGC is outperforming.

The state owns the company, the state also sets the tax, and everyone acts surprised when the two interests occasionally conflict — that’s not a market inefficiency, that’s just Tuesday in a public sector energy company, and the investors who forget it are the ones who call it a betrayal when it happens.
