Wholesale Price Index (WPI)
The Wholesale Price Index represents the price of a basket of wholesale goods. WPI focuses on the price of goods that are traded between corporations. It does not concentrate on goods purchased by the consumers.
- The main objective of WPI is monitoring price drifts that reflect demand and supply in manufacturing, construction and industry.
- WPI helps in assessing the macroeconomic as well as microeconomic conditions of an economy.
Importance of WPI
- In a dynamic world, prices do not remain constant.
- The inflation rate calculated on the basis of the movement of the Wholesale Price Index (WPI) is an important measure to monitor the dynamic movement of prices.
- As WPI captures price movements in a most comprehensive way, it is widely used by Government, banks, industry and business circles.
- Significant monetary and fiscal policy changes are often linked to WPI movements.
- Similarly, the movement of WPI serves as an influential determinant, in the formulation of trade, fiscal and other economic policies by the Government of India.
- The WPI indices are also used for the purpose of escalation clauses in the supply of raw materials, machinery and construction work.
- WPI is used as a deflator of various nominal macroeconomic variables, including Gross Domestic Product (GDP).
