NEWS: The Government of India has decided to gradually replace the Wholesale Price Index (WPI) with a more comprehensive Producer Price Index (PPI) over the next five years.

CONTEXT

• The Department for Promotion of Industry and Internal Trade (DPIIT) àwill release a revised WPI series with base year 2022-23 on June 15.
• Simultaneously, India will introduce a new Producer Price Index (PPI) series, which is expected to eventually replace WPI after five years.

Wholesale Price Index (WPI)

• WPIà Measures the average change in prices of goods traded at the wholesale level before they reach consumers.
• Mainly captures the prices of goods and does not adequately cover the services sector.
• The current WPI series uses 2011-12 as the base year.
• WPI has traditionally been used in India for measuring inflation in producer and wholesale markets.

Producer Price Index (PPI)

• Producer Price Index (PPI) à Measures the average change in prices received by producers for their goods and services over time.
• Tracks inflation from the perspective of producers rather than consumers.
• PPI includes both goods and services, making it a more comprehensive indicator than WPI.
• It helps understand cost pressures faced by producers and their transmission into the broader economy.

India Shifting from WPI to PPI

• WPI àPrimarily focuses on goods and excludes a large part of the modern economy represented by services.
• PPI provides a more complete picture of inflation by covering inputs, outputs, and services.
• It allows policymakers to understand how rising production costs affect final prices.
• The transition brings India's inflation measurement framework closer to international standards.
• PPI is considered a more effective tool for economic analysis and policymaking.

New WPI Series

• The revised WPI will have 2022-23 as the new base year.
• It will replace the existing 2011-12 base year series.
• WPI will continue to be published for the next five years alongside PPI.
• After the transition period, WPI is expected to be discontinued.

Components of the New Producer Price Index (PPI)

• The new PPI will consist of three separate indices.
  • Output PPIà Measures price changes in goods and services sold by producers.
  • Input PPIà Measures price changes in raw materials and inputs used in production.
  • Services PPIà Tracks price movements in various service sectors.

Importance of Output PPI and Input PPI

• Output PPIà helps measure changes in the prices of products sold by producers.
• Input PPI àmeasures changes in the cost of raw materials and intermediate goods used in production.
• Together, they help understand how increases in input costs are passed on to final product prices= provides valuable insights into inflationary pressures within different industries.

Role of DPIIT

• The Department for Promotion of Industry and Internal Trade (DPIIT) is responsible for compiling and publishing both WPI and PPI.
• It functions under the Ministry of Commerce and Industry.
• DPIIT will release monthly data for both WPI and Output PPI.

Why Will WPI Continue for Five Years

• WPI is widely used in price escalation clauses in contracts and agreements.
• Immediate discontinuation could create difficulties for businesses and government agencies.
• The five-year transition period will allow users sufficient time to adapt to the new PPI framework.
• After this period, PPI is expected to become the primary producer inflation indicator in India. Global Significance
• Most advanced economies use Producer Price Index (PPI) as a key measure of producer-level inflation.
• The shift reflects India's efforts to modernize its statistical system.
• The move is consistent with recommendations made by the International Monetary Fund (IMF).

Detailed Explanation

• Inflation can be measured at different stages of the economy using various indices.
• Consumer Price Index (CPI) measures inflation faced by consumers.
• Wholesale Price Index (WPI) measures inflation at the wholesale stage.
• Producer Price Index (PPI) measures inflation experienced by producers and businesses.
• PPI is considered superior because it captures price changes in both goods and services and tracks inflationary pressures more comprehensively.
• By introducing PPI, India will gain better tools for monetary policy, industrial analysis, and inflation forecasting.
