India CPI at 3.93%: RBI Rate Hike Odds Drop as Q1 Undershoot Looms

For bond traders and equity investors, India's latest inflation data offers a tactical reprieve: with Q1 CPI likely undershooting the RBI’s 4.2% target, the central bank is now unlikely to front-load a rate hike in August. That dovish shift supports asset prices in the near term, but the underlying uptick in food and services momentum means the H2 outlook remains heavily contingent on monsoon outcomes and global crude.

India's retail inflation trajectory is providing the Reserve Bank of India with a critical window to hold interest rates steady through the first quarter of FY27, even as subtle pressures build beneath the headline numbers. The May consumer price index (CPI) print rose to 3.93% year-on-year, up from 3.48% in April, driven by a strong sequential momentum of 0.75% month-on-month – the sharpest gain since April of the prior year. Yet, Yes Securities, a domestic brokerage, anticipates that the average CPI for Q1FY27 will undershoot the RBI’s own 4.2% forecast, buoyed by favorable base effects and the relatively contained headline figure. This expectation has materially lowered the probability of an early rate hike, with the RBI now likely to stay “data-dependent” rather than front-load any tightening in August.

Core CPI, which excludes volatile food and fuel, rose to 3.9% in May from 3.7% in April, with its sequential momentum accelerating to 0.50% from 0.35%.

The easing of immediate rate hike fears masks a complex and uneven price landscape. While headline and core inflation remain within the central bank’s 2-6% tolerance band, specific categories are flashing warning signals. Core CPI, which excludes volatile food and fuel, rose to 3.9% in May from 3.7% in April, with its sequential momentum accelerating to 0.50% from 0.35%. This suggests that underlying demand-side pressures are gradually firming up. More striking is the revival in food inflation: after months of deflation in perishables, vegetable prices surged 2.45% month-on-month, with tomatoes spiking 25.6%, potatoes 4.5%, and onions 2.10%. Food and beverages inflation accelerated to 4.5% from 4.0% in April, a jump that, if sustained, could rapidly erode the current policy comfort.

Fuel prices also turned positive on a sequential basis after a negative reading in April, rising 0.4% month-on-month, though electricity continues to show annual deflation of -3.1%. The broader transport category was led by a 1.9% month-on-month increase in petrol and diesel pump prices, which, together with rising restaurant and personal care services, points to budding cost-push impulses. The RBI has already revised its oil price assumption upward to $95 per barrel for policy calculations, from $85 earlier, reflecting the global commodity environment. This adjustment alone embeds a higher inflation trajectory in the central bank’s modeling, but for now, the near-term data suggests that the March quarter’s low base will keep the average in check.
