The government today approved a proposal to release wholesale prices-based inflation data on a monthly basis, instead of every week now, and changed the base year to 2004-05 from 1993-94.

However, data on primary and fuel items would continue to be released on weekly basis. "The new series of WPI (Wholesale Price Index) inflation with 2004-05 as base year would be launched soon," Commerce and Industry Minister Anand Sharma told reporters after a meeting of the Cabinet Committee on Economic Affairs.
