Higher prices of food products and some manufactured items pushed up inflation to 3.21 per cent for the week ended on November 17, against 3.01 per cent a week ago.
However, the wholesale price-based index, inflation, was way below the RBI projection of close to 5 per cent for this fiscal.
The inflation stood at 5.56 per cent a year ago.
Although inflation was still below the RBI's projection for this fiscal, analysts said they do not anticipate cut in interest rates, which has started telling on the economic growth.
Also, with crude hovering over $90 a barrel in the global markets, and food and commodity prices firming up, inflationary expectations are still large, they said, adding that the apex bank might not go for soft interest regime soon.
The wholesale price index, on which inflation data is based, rose marginally by 0.1 per cent to 215.7 points from 215.4 points during the week.
While most food products turned expensive, prices of fruits fell by 0.3 per cent and pulses by 0.8 per cent.
Prices of vegetables rose by 3.4 per cent, condiments and spices by 0.4 per cent, pulses by 0.4 per cent and eggs, meat and fish by 0.4 per cent.
More specifically, prices of bajra were up 6 per cent, jowar 2 per cent and arhar and pork by 1 per cent each.
