Key Highlights
- The Union Government has set up an 18‑member expert committee on 2 January 2025.
- The panel’s mandate is to shift the Wholesale Price Index (WPI) base year from 2011‑12 to 2022‑23.
- Professor Ramesh Chand of NITI Aayog will chair the committee, which includes economists, financiers and statisticians.
- Key tasks cover commodity selection, revision of price‑collection methods, computational techniques, and a roadmap for migrating to a Producer Price Index (PPI).
- The final recommendations are due within an 18‑month horizon, aiming to improve the accuracy of inflation‑adjusted national accounts.
Detailed Insights
The newly constituted committee is expected to confront the structural transformations that have unfolded across the Indian economy in the last decade, notably the surge of the services sector which now accounts for more than half of gross domestic product. By adopting 2022‑23 as the reference year, the WPI will better capture contemporary price dynamics and provide a more reliable deflator for converting nominal GDP into real terms.
Beyond merely updating the base year, the panel will review the existing price‑collection framework, recommending enhancements that could reduce lag, broaden coverage and align methodology with international best practices. It will also devise computational formulas for both the WPI and the proposed PPI, ensuring statistical consistency across the two indicators.
One of the most consequential elements of the mandate is the formulation of a transition strategy from the WPI, which traditionally monitors only goods, to a comprehensive PPI that incorporates services at various stages of production. This shift mirrors practices in many advanced economies and is intended to furnish policymakers with a more holistic picture of producer‑level inflation.
The committee’s work will culminate in a detailed report, to be submitted within 18 months, that will guide the Ministry of Commerce and the National Statistical Office in publishing revised series and calibrating related policy tools such as wage indexation and monetary‑policy targets.
Key Concepts
- Wholesale Price Index (WPI): A producer‑focused index measuring average wholesale prices of goods, excluding taxes, discounts and logistics costs.
- Consumer Price Index (CPI): An indicator of retail inflation that tracks prices of a basket of consumer goods and services, informing wage adjustments and RBI’s inflation target.
- Producer Price Index (PPI): A forthcoming metric that will encompass both goods and services at the production stage, offering a broader gauge of price pressures across the economy.
- Base Year Revision: The statistical exercise of selecting a new reference year to reflect current economic structures and improve the relevance of price indices.
- Price‑Collection System: The institutional mechanism through which price data are gathered from markets, wholesalers and service providers for index computation.
