Inflation for the month of August stood at 8.51 per cent, according to the new Wholesale Price Inflation (WPI) series released by the government on Tuesday.
As per the old series with a base year of 1993-94, WPI inflation stood at 9.5 per cent for the month, according to the Commerce Ministry.
Overall inflation in August witnessed a fall of 1.27 percentage points from 9.78 per cent in the month of July, as per the new series, which considers 2004-05 as the base year.
As per the new WPI index, inflation was 0.31 per cent in August last year.
"It (the new index) will help in informing both the government and people how the prices are moving. This will give a robust picture and reflect actual price movement," Commerce Minister Anand Sharma told reporters in New Delhi.
He said food inflation is still a cause of concern.
As per the new WPI data released on Tuesday, prices of primary articles -- food, non-food articles and minerals -- shot up by 15.76 per cent on an annual basis.
