Retail inflation may hit 5% by June 2026: RBI waits

Why the inflation narrative has shifted again

Retail inflation is back in focus after a series of fuel price increases and higher import duties on gold and silver. Economists tracking the Consumer Price Index (CPI) now see a near-term rise in inflation prints, with June 2026 potentially approaching 5%. The key question for markets is whether the Reserve Bank of India (RBI) responds quickly through interest rates or treats the move as a temporary, cost-driven shock.

Most economists cited in the reports expect the RBI to stay on a wait-and-watch path in the June policy review. The broad argument is that repo rate changes have limited ability to counter inflation that is being pushed up by input costs such as fuel. Instead, the central bank is expected to monitor how much of the fuel increase passes through to wider prices over the next quarter.

What happened to petrol and diesel prices

Over an 11-day period starting May 15, retail fuel prices were raised multiple times. Petrol prices rose by Rs 7.38 per litre and diesel by Rs 7.48 per litre, with some inter-city variation. One estimate in the coverage described the overall increase as averaging about Rs 7.5 per litre in petroleum products.

The timing matters because fuel moves can affect both transport costs and a range of goods and services. Traders also flagged that one reason monetary policy had not needed to counter inflation earlier was that retail fuel prices had not been raised until now.

How fuel increases can feed into CPI

Economists provided different estimates of how much these hikes may lift the CPI inflation rate.

EY India Chief Policy Advisor D K Srivastava told PTI that after an overall increase averaging about Rs 7.5 per litre in petroleum products, CPI inflation could go up by about 75 basis points. Barclays, in a note, estimated that an increase of 15 basis points in CPI inflation from June would be attributable to an approximately 3% rise in retail fuel prices. Barclays economists also said the direct impact on CPI inflation is 15 basis points when fully passed through.

These estimates sit alongside market chatter that participants were already pencilling in at least 10-20 basis points into the inflation print.

Economists’ CPI inflation ranges for May and June

Forecasts in the reports point to a step-up in inflation readings from May into June.

Srivastava said May 2026 CPI inflation may be in the range of 4-4.5%, and June CPI may be in the range of 4.5-5%. The CPI inflation data for May is scheduled to be released on June 12.

India Ratings & Research Director Megha Arora said she expects June CPI to surpass 4% but remain within the RBI’s upper tolerance band of 6%. She also said that based on the four fuel price hikes so far, June CPI inflation is likely to be higher by around 38 basis points, with an upside risk from further pass-through.

RBI’s likely approach: wait, then evaluate pass-through

A repeated theme is that the RBI may prefer to observe the impact of the fuel price hike before considering interest rate changes later in the fiscal year. Srivastava said that because the increase in CPI is cost driven, adjustments in the repo rate may have limited effect in containing inflation. He added that the RBI may like to wait until the fuel price hike settles down and examine its impact over a quarter before taking a decision.

However, he also flagged a condition that could change the reaction function: if CPI inflation crosses 5% and shows upward momentum, the RBI may start tightening interest rates.

June policy review: dealers see no immediate hike

Dealers and bond traders cited in the reports said the marginal fuel-led rise is not likely to push the RBI’s Monetary Policy Committee into a rate hike at the next meeting in June. One market participant, the head of trading at a foreign bank, said the hike was not enough for the RBI to justify a complete shift in June from a wait-and-watch stance into tightening action.

Dealers also pointed to recent RBI commentary that central banks can look through temporary supply-side shocks on inflation without acting. The reports referenced comments by RBI officials including Governor Sanjay Malhotra.

Repo rate expectations and what the RBI is watching

The RBI is expected to keep the repo rate on hold at 5.25% for now, according to the coverage. The central bank is expected to watch three factors closely: the trajectory of global crude oil prices, the monsoon’s impact on food inflation, and the impact of the fuel price rise and how much wholesale inflation passes through to retail inflation.

Economists also expect wholesale inflation to remain high in the near term and touch 9% in May as the West Asia crisis continues to keep global crude and commodity prices elevated.

FY27 inflation forecasts are being revised higher

Several institutions cited in the reports indicated that FY27 inflation expectations are drifting higher.

For FY27, bond traders and economists expect India’s CPI inflation to be close to 5.0% rather than the 4.6% projection the RBI gave in April. Both are above the RBI’s target of 4.0%.

CRISIL’s latest report projects retail inflation could rise to 5.1% this fiscal amid elevated crude oil prices, a weaker rupee, and global supply disruptions linked to the Iran conflict. Separately, Madhavi Arora, chief economist at Emkay Global, said Emkay raises FY27 headline inflation to 5% versus 4.6% earlier, assuming a Rs 10 per litre hike in retail fuel prices along with the impact of El Niño-led adverse monsoons.

What to watch next

The immediate marker for investors is the May CPI print due on June 12, and how it compares with the 4-4.5% range cited by EY. After that, the June inflation reading and the extent of pass-through from fuel into broader prices will be critical to the RBI’s assessment over the next quarter.

Markets are also tracking crude oil prices, the monsoon’s effect on food inflation, and whether wholesale price pressures feed into retail inflation more strongly than expected. Those variables will shape whether inflation stays near 5% for longer or eases after the initial fuel shock.

Conclusion

Fuel price hikes and higher import duties on gold and silver have raised the risk of CPI inflation moving toward 5% by June. Economists expect the RBI to keep the repo rate on hold in the June review and assess the pass-through over a quarter before considering tightening later in the fiscal year, especially if inflation shows sustained upward momentum.
