Phase IFoundation

Background

Overview

Understanding different inflation measures is fundamental for economic analysis and policy formulation. The shift from WPI to PPI in data computation (e.g., for IIP) signifies an important methodological improvement and reflects India's alignment with global best practices in economic statistics.

Price indices like the Wholesale Price Index (WPI) and Producer Price Index (PPI) are crucial macroeconomic indicators used to measure inflation. WPI tracks price changes at the wholesale level, while PPI measures the average change over time in the selling prices received by domestic producers for their output.

Phase IIStatic core

Facts & tables

Key facts

WPI Scope

Measures inflation at the first point of bulk transaction; primarily covers goods.

PPI Scope

Measures price changes from the producer's perspective, reflecting revenue received; can include both goods and services.

Inclusions

PPI typically includes indirect taxes and subsidies, providing a more accurate reflection of net realization for producers, unlike WPI which often excludes them.

Global Trend

There is a global shift towards PPI as a more comprehensive and accurate measure of producer inflation compared to WPI.

Quick revision

  • WPI: measures wholesale prices, primarily goods.
  • PPI: measures producer selling prices, includes goods and potentially services.
  • PPI reflects producer's net realization (includes taxes/subsidies).
  • Global trend towards PPI for better accuracy in producer inflation.
  • MoSPI adopted PPI as a deflator for some IIP sectors.

Elimination traps

Constitutional vs statutory — Confusing the distinct scopes, methodologies, and policy applications of WPI, PPI, and CPI (Consumer Price Index) in measuring inflation.

Check if created by Constitution or by Parliament.
