Crude oil shock: why India inflation may rise 2026

Oil is back as an inflation driver

Higher fuel costs linked to the Iran war are starting to feed into prices. The Reserve Bank of India’s Monetary Policy Report offers a simple rule of thumb on pass-through. A sustained $10-a-barrel rise in crude lifts headline inflation by about 0.3-0.4 percentage points over a few months. Against that yardstick, the current oil shock looks large. The Indian crude basket is now stated to be $16 above its pre-war level. That framing implies the April 3.48 percent inflation print is being seen as a floor for this cycle, not the ceiling. The immediate question for households and investors is how long the oil spike lasts and how much is passed through.

Indian crude basket: from $19 to triple digits

India’s crude basket, a weighted average of Brent and Dubai-Oman grades imported by Indian refineries, closed at $105 a barrel in May. It was $19 in February when the war began. The basket peaked at $114 in April, its highest reading in more than three years. The only comparable spike in the five-year monthly series was in mid-2022, during the early months of the Russia-Ukraine war. Brent has stayed above $100 a barrel in this period. Separately, one breakdown noted Brent moved from about $10 to $120 a barrel after the war began, and briefly crossed $120 on April 30. Another segment referenced a surge from $12 to near $144 per barrel.

Strait of Hormuz: the key transmission channel

The mechanism flagged repeatedly is the Strait of Hormuz. The narrow waterway between Iran and Oman typically carries about a fifth of the world’s oil and LNG trade. It has been described as effectively shut since the war began on February 28, amid a truce that has held only on paper. This matters directly for India’s energy security. India imports nearly 90 percent of the crude it consumes, and a large share of that flows through Hormuz. With Brent above $100, freight, insurance, and availability concerns can amplify the landed cost. And those costs show up in the economy through fuel, transport, and petrochemical inputs.

Why retail fuel prices have stayed unchanged

Despite the surge in global crude prices and supply disruptions, India has held retail fuel prices steady through policy and balance-sheet absorption. Petrol and diesel prices have been unchanged since February 28, as per the explainer cited in the provided text. The Centre cut excise duty by ₹10 per litre on petrol and diesel. It also absorbed up to ₹24 per litre on petrol and up to ₹30 per litre on diesel at peak, according to the same breakdown. This strategy delays direct inflation at the pump, but it shifts stress elsewhere. It can raise fiscal trade-offs and deepen losses at oil marketing companies.

OMC losses and the rupee effect are now central

Losses absorbed by oil firms were estimated at ₹30,000 crore since mid-March in one estimate. That same segment said losses could have hit ₹62,500 crore without excise cuts. Another key change highlighted is INR depreciation. A commentary noted that even if Brent in dollar terms is not at its highest, Brent in rupee terms is at a record, cited at around ₹11,000 per barrel when crude is $120. It also said crude is now available at a premium and even Russian crude is available at a premium, unlike 2022. These factors increase the burden on oil marketing companies even when global dollar prices are not making new highs.

Kotak Securities and “street” expectations on price hikes

At $120 per barrel crude, oil marketing companies are seeing a burden of nearly ₹27,000 crore a month, as per Kotak Securities cited in the text. The same note said they would require a price hike of close to ₹25-₹28 per litre to offset the impact. Yet it also cited OMC reserves of around ₹3.27 lakh crore. Based on that, it argued the companies could theoretically bear the burden for about 10 months if they avoid hikes. Market expectations described in the text are more limited. If crude stays above $100 per barrel, the street is expecting a hike of up to ₹5 per litre, with diesel seen facing a sharper hike than petrol.

Macro linkages: inflation, CAD, and growth estimates

Beyond fuel retail pricing, macro estimates underline the second-order effects. One explainer said India imports around 85 percent of its crude oil and that at $100 oil, India’s annual import bill rises by roughly $15-$16 billion, or nearly 0.8 percent of GDP, from the price increase alone. It also noted that even a moderate price rise can add 0.7-0.9 percentage points to headline inflation. Another RBI-linked estimate cited said every 10 percent rise in oil can shave off 15 basis points from GDP growth and push inflation up by 30 basis points. Ratings agency ICRA added a current account and fiscal layer. It said every $10 increase in the average crude price for the year would widen India’s CAD by 30-40 basis points, and that an average price of around $100-$105 per barrel would imply a CAD of 1.9-2.2 percent of GDP.

Sector map: winners, losers, and policy buffers

ICRA’s report highlighted divergent effects across the energy value chain. Upstream producers could benefit, with analysts estimating profit before tax for ONGC and Oil India could rise by about ₹57,800 crore over FY26 levels if crude averages $100-$105. But downstream stress builds quickly. ICRA said crude at $100-$105 translates into an ₹11 per litre impact on petrol marketing margins and ₹14 per litre for diesel. Elara Capital’s estimates in the same text suggested that for every $10 rise in crude, OMCs’ diesel and petrol margin falls by ₹6.3 per litre and LPG loss rises by ₹10.2 per kilogram, implying a ₹32,800 crore rise in annual LPG under-recovery. The report also flagged an excise buffer, citing duties of ₹19.9 per litre on petrol and ₹15.8 per litre on diesel, with retail prices potentially protected through excise cuts until around $110 crude, but hikes becoming “inevitable” beyond that level.

Markets have stayed resilient so far

Despite the energy shock narrative, equity indices have not moved one-for-one with crude. The text stated oil prices jumped 28 percent in two weeks, while the Nifty 50 slipped 1.8 percent over the same period. It also said the Nifty is still up 7 percent, while midcaps and smallcaps are outperforming. One explanation offered is that India’s oil sensitivity has structurally reduced, with crude imports as a share of GDP nearly halving from 9 percent in 2013 to around 4.8 percent in 2025. But the remaining dependence remains high given the 85-90 percent import share figures cited across the provided material. That keeps inflation, CAD, and rupee channels relevant for earnings and policy.

Key numbers at a glance

What to watch next

The near-term path depends on whether crude stays above $100 and how long disruption risks around the Strait of Hormuz persist. As long as retail prices are held steady, the pressure shifts to excise buffers, OMC balance sheets, and broader fiscal choices. If prices remain elevated, the RBI’s oil-to-inflation rule of thumb suggests headline inflation could face measurable upward pressure over the next few months. ICRA’s CAD sensitivities also put focus on external balances if average crude stays around $100-$105. On the corporate side, upstream earnings may strengthen while marketing margins and LPG under-recoveries become harder to absorb. Investors will also track whether any retail price adjustments occur, and if so, whether diesel moves first as the “street” expectation suggests.
