Fuel price hikes to lift CPI to 5% by June 2026

What is driving the fresh inflation concern

Fuel price hikes and higher import duties on gold and silver are expected to add to near-term retail inflation pressures, economists said. The concern is that higher pump prices feed into transportation and logistics costs, and then into the prices of goods and services. Some economists also flagged that milk prices have risen recently, adding to household inflation. Together, these factors could push the Consumer Price Index (CPI) higher through May and June readings. The June CPI data is expected to capture the fuller pass-through from the recent fuel increases.

The latest fuel hike and why it matters

State-run oil marketing companies raised petrol and diesel prices by up to ₹3 per litre on Friday, the first increase in four years, amid a sharp rise in global crude oil prices linked to the West Asia conflict. Analysts cautioned that even a single hike can move the inflation needle because fuel costs influence multiple parts of the economy. Economists expect the first signs of higher fuel costs to show up in the May CPI print, with fuller transmission into June. June CPI data is expected to be released in mid-July. The immediate focus, therefore, is on how much of the fuel increase gets passed on to freight, services, and retail prices.

EY’s estimate: 75 bps impact from cumulative hikes

EY India Chief Policy Advisor D K Srivastava said that after an overall increase averaging about ₹7.5 per litre in petroleum products, CPI inflation would rise by about 75 basis points (bps). Based on this assessment, he expects May 2026 CPI inflation to be in the range of 4% to 4.5%. For June, EY sees CPI inflation in the range of 4.5% to 5%. This is one of the higher-end projections cited by economists in the discussion, and it underscores the cumulative effect of repeated fuel price increases.

India Ratings: June CPI may rise by about 38 bps

India Ratings & Research Director Megha Arora said that based on the four fuel price hikes so far, June CPI inflation is likely to be higher by around 38 bps. She also flagged upside risk from further pass-through. Even with this increase, she said June CPI is likely to surpass 4% but remain within the RBI’s upper tolerance band of 6%. The key point is that inflation could firm up without necessarily moving into a zone that forces immediate monetary tightening.

Other forecasts and estimates cited by analysts

CRISIL’s latest report projects retail inflation could rise to 5.1% this fiscal year, citing elevated crude oil prices, a weaker rupee, and global supply disruptions linked to the Iran conflict. Analysts quoted by the Times of India estimated fuel price hikes could add 10 to 25 bps to headline inflation in the coming months. IDFC First Bank chief economist Gaura Sengupta said the latest fuel price change alone could add 12 bps to headline CPI inflation, and she estimated May inflation at around 3.9%. She also said retail petrol and diesel prices could cumulatively rise by up to 10% over the next few months and projected FY27 CPI inflation could average 4.9%.

How direct and indirect effects add up

Radhika Rao, senior economist and executive director at DBS Bank, said that given the weightage of petrol and diesel in the CPI basket, a 3% to 5% increase likely adds 15 to 25 bps to the headline print, besides second-round inflationary effects. CareEdge Ratings chief economist Rajani Sinha said retail fuel prices could directly add 15 bps to inflation, while higher transportation, logistics, and agricultural input costs may create additional indirect pressures of 10 to 15 bps. Petrol and diesel together account for 4.8% of the CPI basket, which is why the direct impact is measurable. But economists repeatedly flagged that the bigger swing can come from second-round effects.

Transport and logistics: a key channel for pass-through

Transporters and industry groups have warned that rising diesel costs, along with tolls, tyres, and vehicle maintenance, may push companies to raise prices across sectors. Freight rates for goods transported by road are likely to rise by 2.5% to 3%, according to the All India Transporters Welfare Association (AITWA). Higher freight rates can affect prices for staples and manufactured goods because road transport remains a major distribution channel. Economists said these cascading impacts are a key reason June inflation is being closely watched.

RBI stance: wait-and-watch, with H2 tightening possible

Economists said the Reserve Bank of India is likely to wait and watch until the inflation impact of the fuel price hike settles in. Rate tightening is expected only in the second half of the fiscal year, based on the economists’ assessment cited in the report. The central bank’s tolerance band for inflation tops out at 6%, and several economists said the likely June print should remain below that level even if it rises above 4%. The near-term question is the pace and breadth of pass-through rather than an immediate breach of the inflation ceiling.

Why the story matters for markets and households

For households, higher fuel prices usually show up first through commuting and transport-linked services, and then through broader goods inflation as supply chains adjust. For businesses, higher logistics costs can pressure margins or lead to price increases, depending on demand conditions. For investors, the key issue is whether inflation moves sustainably higher and changes the RBI’s rate path later in the fiscal year. Economists highlighted that June inflation data, due in mid-July, will be important because it is expected to show the fuller impact of the fuel hike. Until then, the broad expectation remains that inflation may firm up toward 4.5% to 5% without breaching the RBI’s 6% tolerance limit.

Conclusion

Economists expect fuel price hikes, along with higher import duties on gold and silver and rising milk prices, to lift India’s retail inflation through May and June. Estimates cluster around June CPI crossing 4% and potentially approaching 5%, with some forecasts pointing to 5.1% inflation for the fiscal year. The RBI is expected to stay in wait-and-watch mode until the fuel-driven impact settles, with any tightening seen in the second half of the fiscal year. The next key milestone is the June CPI print, scheduled for release in mid-July, which is expected to capture the fuller transmission of the recent fuel increases.
