After a gap of over five months, food inflation entered the double-digit zone at 10.05 per cent for the week ended August 20, with Finance Minister Pranab Mukherjee describing the trend as "disturbing" and experts saying RBI may go in for another rate hike.
The weekly food inflation, measured by Wholesale Price Index (WPI), went up from 9.80 per cent on account of expensive onion, vegetables, fruits and protein-based items.
The last time food inflation crossed 10 per cent was in the week ended March 12.
"Food inflation has gone up... This is really disturbing. We shall have to ensure and remove the supply constraints on food items," Mr. Mukherjee told reporters here.
As per the official data released today, prices of onion soared by 57.01 per cent year-on-year and potato rose by 13.31 per cent during the week under review.
Fruits became dearer by 21.58 per cent and vegetables overall by 15.78 on an annual basis.
Prices of protein rich items, egg, meat and fish were up 12.62 per cent, while milk and cereals became dearer by 9.22 per cent and 4.64 per cent respectively.
Attributing the jump in food inflation to seasonal factors, experts opined it could again force the Reserve Bank to hike interest rate during its mid-quarter monetary policy review scheduled on September 16.
"With headline inflation remaining well above 9 per cent, we expect RBI to raise key policy rates by 25 basis points at its next mid-quarterly review," Crisil chief economist D K Joshi said.
Food items constitutes about 14 per cent to the WPI.
Mr. Joshi said seasonal factors like supply problems due to heavy rainfall in parts of the country is pushing up the food inflation.
He, however, said as monsoon has been good so far, prices of vegetables may come down in the coming days.
Planning Commission Deputy Chairman Montek Singh Ahluwalia too said seasonal factors are pushing up inflation.
"Inflation is a worry... If you see the data, last year at this time food prices went down and then rose again. So I would not be surprised if prices rise a little bit," Mr. Ahluwalia said.
Overall, primary articles recorded 12.93 per cent inflation for the week ended August 20, up from 12.40 per cent in the previous week. Primary articles have a share of over 20 per cent in the WPI.
However, inflation in non-food articles, like fibers, oilseeds and minerals, stood at 17.19 per cent, down from 17.80 per cent in the previous week.
As per the data, fuel and power inflation was at 12.55 per cent for the week ended August 20, down from 13.13 per cent in the previous week.
"I expect food inflation to come down in the coming weeks ... as the monsoon has been good. We are almost towards the end of the monsoon and all indications are that the agricultural production will be good during this year," Prime Minister's Economic Advisory Council Chairman C Rangarajan said.
