Inflation in the ‘fuel and power’ basket in December slumped to 8.38 per cent, nearly half of 16.28 per cent in November. This was on account of lowering of prices of petrol and diesel through December.

Data for retail or consumer price index-based inflation would be released later in the day.
The Reserve Bank of India (RBI) mainly takes into account retail inflation data while formulating monetary policy.
In its fifth monetary policy review for the fiscal, last month, the Reserve Bank kept interest rates unchanged, but held out a promise to cut them if the upside risks to inflation do not materialise.
The central bank lowered retail inflation projection to 2.7-3.2 per cent for the second half of the current fiscal, citing normal monsoon and moderate food prices.
