Why in News?
The government has decided to gradually phase out the Wholesale Price Index (WPI) over the next five years and replace it with the Producer Price Index (PPI).
- The Producer Price Index 2026 aims to provide a more comprehensive assessment of inflation by covering goods, inputs and services.Β
What is Producer Price Index (PPI)?
The Producer Price Index (PPI) measures changes in prices received by producers for goods and services at different stages of production. Unlike WPI, it captures price movements across manufacturing inputs, outputs and services, making it a more comprehensive indicator of producer inflation
Components of PPI
The new PPI framework consists of three indices:
- Output PPI β Measures prices received by producers for finished goods.
- Input PPI β Measures prices paid by producers for raw materials and intermediate goods.
- Services PPI β Tracks producer prices in service sectors such as banking, insurance, telecom, railways and aviation.
WPI vs PPI
| Feature | WPI | PPI |
|---|---|---|
| Coverage | Goods only | Goods and Services |
| Stage Measured | Wholesale level | Multiple stages of production |
| Services Included | No | Yes |
| Input Prices | No | Yes |
| Inflation Measurement | Limited | More comprehensive |
| International Practice | Less common | Widely used globally |
Significance
The Producer Price Index 2026 aligns Indiaβs inflation measurement system with international standards. By covering services and production inputs, it provides a more realistic picture of cost pressures in the economy. The transition will also help policymakers, businesses and researchers better assess inflation trends and formulate economic policies
