The Ministry of Statistics and Programme Implementation (MoSPI) is set to release new item weights for the Consumer Price Index (CPI) before the actual inflation data, signaling an update to the CPI's base year. Currently, the CPI uses 2012 as its base year, but consumption patterns in India have significantly evolved since then, necessitating a revision. This update is crucial because CPI measures retail inflation, directly impacting household budgets and RBI's monetary policy decisions.
The new weights will reflect current spending habits across various categories like food, fuel, housing, and services for both rural and urban populations, providing a more accurate picture of inflation. This move is expected to enhance the credibility and relevance of India's key inflation gauge.

Background
India's statistical system, particularly for inflation measurement, has evolved significantly. Historically, the Wholesale Price Index (WPI) was the primary inflation gauge.
However, with the adoption of an inflation-targeting framework by the Reserve Bank of India (RBI) in 2016, the Consumer Price Index (CPI) became the key metric for monetary policy decisions. The base year for CPI is periodically updated to reflect changes in consumption patterns and economic structure, ensuring the index remains relevant and accurate.

Practice Questions (MCQs)
1. Consider the following statements regarding inflation measurement in India: 1. The Consumer Price Index (CPI) measures changes in the average price of goods and services purchased by wholesale businesses. 2. The Reserve Bank of India (RBI) primarily uses the Wholesale Price Index (WPI) for its monetary policy decisions. 3. The Ministry of Statistics and Programme Implementation (MoSPI) is responsible for calculating the CPI for all-India. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. CPI measures retail inflation, i.e., changes in prices of goods and services purchased by consumers. WPI measures wholesale prices. Statement 2 is incorrect. The RBI, particularly the Monetary Policy Committee (MPC), primarily uses the CPI (Combined) as its key inflation gauge for monetary policy decisions. Statement 3 is correct. The National Statistical Office (NSO) under MoSPI is responsible for calculating CPI (Combined) and other CPI variants.
2. In the context of updating the Consumer Price Index (CPI) base year and item weights, consider the following statements: 1. A base year revision is undertaken to reflect the current consumption patterns and economic structure of the population. 2. Changes in item weights within the CPI basket can significantly alter the measured inflation rate, even if individual prices remain constant. 3. The base year for CPI is typically chosen as a period of high inflation to provide a more stable benchmark. Which of the statements given above is/are correct?
- A.1 only
- B.2 only
- C.1 and 2 only
- D.1, 2 and 3
Show Answer
Answer: C
Statement 1 is correct. The primary reason for updating the base year is to ensure that the index accurately reflects the current spending habits and economic realities, as consumption patterns evolve over time. Statement 2 is correct. Item weights represent the relative importance of different goods and services in the average consumer's budget. If the weight of a category with high price increases (e.g., food) is increased, the overall inflation rate will rise, and vice-versa, even if the price changes of individual items remain the same. Statement 3 is incorrect. The base year is typically chosen as a relatively normal year, free from major economic shocks or extreme inflation/deflation, to serve as a stable and representative benchmark for comparison.
3. Which of the following inflation indices is NOT primarily used by the Reserve Bank of India (RBI) for its inflation targeting framework?
- A.Consumer Price Index (Combined)
- B.Consumer Price Index for Industrial Workers (CPI-IW)
- C.Wholesale Price Index (WPI)
- D.Consumer Price Index for Agricultural Labourers (CPI-AL)
Show Answer
Answer: C
The Reserve Bank of India (RBI) adopted an inflation-targeting framework in 2016, with the Consumer Price Index (Combined) (CPI-C) as the primary measure of inflation. While other indices like CPI-IW and CPI-AL are important for specific segments of the population and policy analysis, WPI measures wholesale price changes and is not the primary target for RBI's monetary policy. CPI-IW is compiled by the Labour Bureau and used for dearness allowance revisions for industrial workers. CPI-AL is also compiled by the Labour Bureau and used for agricultural labourers.
