Model Answer

Price indices are crucial indicators for measuring inflation and guiding economic policy. While CPI captures inflation experienced by consumers and WPI tracks price changes at the wholesale level, the proposed Producer Price Index (PPI) aims to measure price changes from the perspective of producers.

Inflation Flow: Producer (PPI) → Wholesaler (WPI) → Consumer (CPI)

Why is India Introducing PPI?

1. Early Warning of Inflation

Detects cost pressures at the production stage before they transmit to wholesale and retail markets.

2. Better Measurement of Producer Costs

Captures changes in input and output prices faced by industries, providing a more accurate picture of business conditions.

3. Addresses Limitations of WPI

WPI largely focuses on traded goods and does not fully capture producer-level price dynamics.

4. Improved Policymaking

Helps government and RBI assess supply-chain bottlenecks, industrial competitiveness and inflationary pressures more effectively.

5. Alignment with Global Practices

Most advanced economies use PPI as a standard indicator for inflation monitoring and economic analysis. Conclusion

The introduction of PPI alongside the revised WPI will create a more comprehensive inflation framework. Together with CPI, it will enable policymakers to track price movements across the entire value chain—from production to consumption—thereby strengthening evidence-based economic decision-making.

Value Addition: PPI → Cost Pressure WPI → Market Price Movement CPI → Consumer Impact

Together, they provide a 360-degree view of inflation in the economy.
