Oil Prices Crash on US-Iran Deal: 5 Stocks That Win Beyond the Obvious

The US-Iran peace deal announced over the weekend sent crude oil prices tumbling, triggering a broad market rally — the Sensex surged over 1,200 points on Monday, with the Nifty approaching 24,000. Auto stocks led the charge, with the Nifty Auto index rising 2.7%. Oil marketing companies like HPCL were among the top gainers.

But these are the obvious plays. The more interesting question for retail investors is: which companies have the deepest exposure to crude-linked raw material costs, where a sustained oil price decline would flow directly into fatter margins?

We dug into corporate filings to find five unexpected beneficiaries.

1. Asian Paints (ASIANPAINT) — The Crude-Margin Link Nobody Watches

Most investors think of Asian Paints as a consumer brand play. What they miss: a significant share of paint raw materials — solvents, phthalic anhydride, pentaerythritol, and monomers — are crude oil derivatives. When crude spiked in FY22-23, Asian Paints' gross margin compressed from 44.8% to as low as 37.6%, per their annual report.

As crude-linked input costs moderated, gross margins recovered to 44.0% in the most recent fiscal year. PBT margins reached what management described as "all-time highs of about 22%" in their Q3 FY26 earnings call. A further sustained drop in crude prices would widen this gap further. With revenue from operations exceeding Rs 30,000 crore annually, even a 1-2 percentage point gross margin improvement translates to Rs 300-600 crore of incremental gross profit.

2. Berger Paints (BERGEPAINT) — Gross Margin Expansion in Real Time

Berger Paints shows the crude-to-margin link even more starkly. Per their quarterly results, gross margins swung from 33.8% in Q3 FY23 (when crude was elevated) to 41.2% by Q4 FY25 — a massive 740 basis point expansion. In their earnings call, CEO Abhijit Roy explicitly attributed this to "raw material price drop, which is the bigger portion of it."

Materials consumed account for roughly 60% of Berger's revenue (Rs 6,089 crore against Rs 10,169 crore in FY25 per their annual report). With operating margins recently ranging between 12.7% and 17.4%, any further crude-driven raw material softening has an outsized impact on the bottom line. Market share has also crossed 20% as of H1 FY24.

3. Apollo Tyres (APOLLOTYRE) — Where Crude Hits Hardest

Tyre manufacturing is one of the most crude-sensitive industries in India. Synthetic rubber, carbon black, and nylon cord are all petroleum derivatives. Per their FY25 annual report, Apollo Tyres reported an approximately 11% increase in raw material costs during FY25, explicitly driven by "rising crude-based materials, especially synthetic rubber" and a weakening rupee.

Their earnings call disclosed the specific input cost basket: natural rubber at Rs 157/kg, synthetic rubber at Rs 167/kg, carbon black at Rs 106/kg, and steel cord at Rs 180/kg. Consolidated EBITDA fell to Rs 21,907 million from Rs 30,966 million the prior year — a 29% decline driven predominantly by raw material inflation. A reversal in crude-linked input prices would provide immediate margin relief, as management noted EBITDA margins have historically ranged from 12% to over 15%.

4. Aarti Industries (AARTIIND) — Benzene and Toluene Are Crude's Children

Aarti Industries is India's leading producer of benzene- and toluene-based downstream chemicals, both of which are direct crude oil derivatives. Per their investor presentations, the company processes over 45,000 tonnes per annum of nitrotoluene and 30,000 tonnes of ethylation products, having recently expanded both capacities.

In their Q2 FY24 earnings call, management reported EBITDA of Rs 233 crore, growing 16% quarter-on-quarter, noting that "near stabilising of realisation for some products" alongside volume expansion drove the improvement. They also flagged Rs 150-200 crore of near-term EBITDA benefit from "yield improvements and raw material cost optimisation." When crude falls, benzene and toluene prices follow — and for a company where these are the primary feedstock, margin expansion can be swift.

5. IndiGo (INDIGO) — The Fuel Math Most Investors Underestimate

IndiGo is the most direct crude oil beneficiary on this list. Aircraft fuel (ATF) is the airline's single largest expense. Per their FY25 annual report, aircraft fuel expenses totalled Rs 261,973 million — roughly 34% of total expenses of Rs 765,048 million. In Q1 FY26, fuel expenses dropped 9.1% year-on-year to Rs 58,326 million even as capacity grew 16%, directly reflecting lower ATF prices.

Management noted on their Q2 FY25 call that fuel CASK (cost per available seat kilometre) declined 16% year-on-year when global fuel prices fell over 20%. The EBITDAR margin stood at 29.7% for Q1 FY25 and reached 31.2% for the full year. Each additional percentage point decline in ATF prices drops straight to the bottom line — IndiGo's scale means even a 5% further decline in ATF prices would save the airline over Rs 1,300 crore annually.

What Retail Investors Should Do

The immediate rally in auto and OMC stocks after the Iran deal is already priced in. The smarter play is to watch companies where crude-linked raw materials are a major cost line but the stock doesn't carry an "oil play" label. Paint companies (Asian Paints, Berger), tyre makers (Apollo Tyres), and specialty chemical firms (Aarti Industries) fit this profile.

The key variable is sustainability. If the US-Iran deal holds and crude stays below $65-70 per barrel, these companies could see 200-500 basis points of margin expansion over the next two to three quarters — and that kind of earnings upgrade tends to drive re-ratings. Monitor the Q1 FY27 results (July-August) for the first concrete evidence of this margin tailwind flowing through.
