What is the Wholesale Price Index?
The wholesale price index also known as WPI, measures the changes in the wholesale prices in India. The manufacturers and the wholesalers pay the prices based on the market demand. The wholesale price index tracks the price change in commodities at the main stages before it reaches the retailers.
In terms of compilation and releasing of this index, the office of the economic advisor is considered the nodal office. RBI used to refer to WPI to make most of its policy decisions before 2014. However, it was used correctly for the calculation of inflation.
The aim of the WPI is to -
- To monitor the shifts in prices that show the demand and supply of manufacturing products in the industry.
- To help assess all the major and minor conditions related to the wholesale prices in the Indian economy.
The wholesale price index is the starting point for determining the growth of the goods' prices until it reaches the consumer. The office of economic advisors of the Ministry of Commerce publishes the index. There are three main categories of goods covered by the index, which are-
- Manufactured goods (Chemicals, apparel, Textiles)
- Primary Products (Food and Non-Food articles)
- Fuel and Power (Gasoline, Petrol, LPG).
