But year-on-year, the Consumer Price Index (CPI) in April was lower than the corresponding period of last year when retail inflation stood at 4.58 per cent.

"April WPI inflation moderated to 3.1 per cent, with sharp uptick in food component being countered by easing in core components," said Madhavi Arora, Economist, FX and Rates, Edelweiss Securities.

"The narrative is mostly similar to the April CPI inflation, with correction in core partly reflecting weaker domestic demand. We see food prices to tick up further in the near-term which could pressurise inflation sequentially."
