"Headline CPI inflation in the fourth quarter of 2016-17 is likely to be below 5 per cent. Favourable base effects and lagged effects of demand compression may mute headline inflation in the first quarter of 2017-18. Thereafter, it is expected to pick up momentum, especially as growth picks up and the output gap narrows," the central bank said.
The apex bank also outlined three significant upside risks that trigger some uncertainty to the baseline inflation path -- the hardening profile of international crude prices, volatility in the exchange rate on account of global financial market developments and the fuller effects of the house rent allowances under the 7th Central Pay Commission (CPC) award.
The focus of the Union Budget on growth revival without compromising on fiscal prudence should bode well for limiting upside risks to inflation, the central bank said.
