Fuel price hike: ₹3 rise may lift CPI 10-25 bps in 2026

What changed in pump prices

Public sector oil marketing companies raised petrol and diesel prices by around ₹3 per litre across metro cities, ending a long stretch of retail stability. DBS Bank’s Radhika Rao said petrol rose by about ₹3.14 per litre to ₹97.77 per litre, while diesel increased by about ₹3.11 per litre to as high as ₹90.67 per litre across several cities. The move is being read as partial relief for state-run retailers that have been absorbing higher crude costs. But it has also revived a key market question: whether this is the start of a broader, phased adjustment.

Why the hike happened now

The immediate backdrop is a sharp rise in global crude prices linked to conflict in West Asia. Analysts and industry executives say the pricing move reflects pressure building on oil marketing company margins. Even after the increase, the gap between retail prices and implied costs has not fully closed. That leaves room, at least arithmetically, for additional revisions if global prices remain elevated and if pricing flexibility is allowed.

Under-recoveries still remain, Crisil says

Ratings agency Crisil estimates that state-run oil marketing companies continue to face under-recoveries of around ₹10 per litre on petrol and ₹13 per litre on diesel even after the latest hike. This data point is central to the debate on further price action because it suggests a large part of the cost pressure remains unaddressed. One expert cited in the reports warned that if crude continues to “build” in the current backdrop, an overall rise of around ₹10 per litre would be required to offset losses. The market takeaway is that the first hike reduces, but does not eliminate, the financial strain.

Direct inflation impact: economists put it at 10-25 bps

Economists expect the fuel increase to lift headline CPI inflation in the coming months, with most estimates clustering in a 10-25 basis points (bps) band. Rao said a 3-5% increase in petrol and diesel likely adds 15-25 bps to the headline inflation print, besides second-round effects. IDFC First Bank chief economist Gaura Sengupta estimated the current change would add about 12 bps to headline CPI inflation on a direct pass-through basis, and pegged May CPI inflation at 3.9% under that assumption. ICRA’s Aditi Nayar expects the hike to push up average retail inflation by around 25 bps on an annualised basis, and said the impact will be spread over May and June because the revision happened mid-month.

Second-round pressures: freight, logistics and wider prices

The bigger concern flagged by economists is transmission beyond the fuel sub-index. CareEdge Ratings’ Rajani Sinha estimated that while fuel prices could directly add about 15 bps to inflation, indirect pressures through transportation, logistics and agricultural inputs may add another 10-15 bps. The All India Transporters Welfare Association said freight rates for road-transported goods are likely to rise by 2.5-3%. Transporters also highlighted cost structure stress, saying diesel alone contributes nearly 50-55% of total truck operating costs, even before factoring tolls, insurance, tyres, maintenance and compliance expenses.

How May and June CPI prints could look

Economists expect the impact to start appearing in the May CPI print, with fuller transmission from June onwards. ICRA has raised its May 2026 inflation projection to 4.3% from 4.1% earlier, according to the report. India Ratings and Research (Ind-Ra) projected 3.8% for May, while IDFC First Bank estimated 3.9%, assuming no further fuel revisions. Recent inflation data shows retail inflation accelerated to 3.5% in April from 3.4% in March, while another cited data point pegged April inflation at 3.48%. The Reserve Bank of India’s inflation target remains 4%, with a tolerance band of 2% on both sides.

Supply-side risk: India’s crude dependence and shipping route constraints

India imports more than 85% of its crude oil requirements, and about half of those imports pass through the Strait of Hormuz, which is described as now mostly blocked in the report. That combination increases sensitivity to geopolitical disruptions and freight risk premia. Separately, economists quoted by IndiaToday.in pointed to Brent crude climbing back above $105 per barrel, which raises the probability of further retail adjustments. Rao also noted that higher pump prices are likely to moderate demand and consequently the import burden, but the immediate effect still feeds into prices.

Could there be another hike, and how big

Several sources in the reports said further increases cannot be ruled out if crude stays elevated. Sengupta said she expects a cumulative rise of up to 10% in retail petrol and diesel prices, including the current increase, spread over the next few months. Another report cited the view that fuel price hikes after May 15 are highly likely with Brent above $105 per barrel, with a possible ₹4-5 per litre increase for petrol and diesel and a ₹40-50 increase for LPG cylinders, while also noting that gradual hikes of ₹2-4 per litre may be preferred to avoid a sudden inflation shock. Separately, the Confederation of Indian Industry recommended that the ₹10 per litre central excise duty cut on petrol and diesel be progressively rolled back in tranches over six to nine months as crude prices stabilise.

Why this matters for markets and policy

A fuel-driven rise in CPI, even if initially modest, complicates the inflation trajectory because fuel costs feed into distribution, mobility and input prices for a wide range of goods and services. Economists cited in the reports said the RBI may have to reassess inflation projections if second-round effects become visible over the next few prints. The policy sensitivity is higher because the hike ends a multi-year freeze and comes at a time when crude remains volatile. Past precedent was also noted: in 2022, authorities raised retail pump prices in two steps cumulatively by around 9-10%, before changes in excise duties and windfall taxes nearly neutralised the overall fiscal impact.

Conclusion

The ₹3-per-litre petrol and diesel hike has eased part of the immediate pressure on state-run retailers, but Crisil’s under-recovery estimates and elevated crude prices keep the risk of further increases in play. Economists broadly see a 10-25 bps direct boost to inflation, with added upside from freight and logistics costs over the next few months. The next inflation prints for May and June, and the trajectory of global crude and shipping disruptions, will shape how quickly and how far retail fuel prices move next.
