The wholesale price index (WPI) is the price of a representative basket of wholesale goods.
The WPI is published by the Economic Adviser in the Ministry of Commerce and Industry. The Wholesale Price Index focuses on the price of goods traded between corporations, rather than the goods bought by consumers, which is measured by the Consumer Price Index. The purpose of the WPI is to monitor price movements that reflect supply and demand in industry, manufacturing and construction. This helps in analyzing both macroeconomic and microeconomic conditions.
Some countries (like the Philippines) use WPI changes as a central measure of inflation. But now India has adopted new CPI to measure inflation. However, United States now report a producer price index (PPI) instead. It also influences stock and fixed price markets.
