India is poised to significantly reduce the weighting of food items within its Consumer Price Index (CPI), marking a pivotal shift in how the nation measures inflation. This re-calibration, expected as part of a new inflation series, aims to better reflect contemporary household consumption patterns across the country. The move is anticipated to have far-reaching implications for monetary policy, government planning, and public perception of economic stability.
Background: The Evolution of India’s Inflation Measurement
India's journey in measuring inflation has seen several transformations, adapting to its dynamic economic landscape. The current CPI series, with a base year of 2012, was introduced in 2014, consolidating separate indices for industrial workers, agricultural labourers, and rural labourers into a unified measure for rural, urban, and combined categories. This standardization provided a more comprehensive gauge of price changes experienced by a broader segment of the population.
The Dominance of Food in the Current CPI
Under the existing methodology, food and beverages command a substantial weight within the CPI basket. For the combined rural and urban index, food and beverages account for approximately 45.86% of the total weight. This figure is even higher in rural areas, exceeding 50%, reflecting the traditional expenditure patterns of Indian households where a significant portion of income is allocated to basic sustenance. While this structure accurately captured consumption in past decades, it has increasingly been seen as less representative of a rapidly urbanizing and developing India.
The National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI) is the nodal agency responsible for compiling and releasing CPI data. Periodic revisions are crucial to ensure the index remains relevant and accurate. The current high food weighting means that transient supply-side shocks, such as erratic monsoons or global commodity price fluctuations, disproportionately influence the headline inflation figure, often masking underlying demand-side pressures in the economy.
Key Developments: The Impending Re-calibration
The impetus for the impending re-calibration stems primarily from the findings of the Household Consumption Expenditure Survey (HCES) 2022-23, which provides updated insights into how Indian households spend their money. Preliminary reports from the HCES indicate a notable decline in the share of food in total household expenditure, especially in urban areas, and a more moderate reduction in rural households. This data forms the bedrock for revising the CPI basket and its associated weights.
New Weighting Structure and Base Year
The most significant change will be the substantial reduction in the weight of food and beverages. While the exact new percentage is yet to be officially announced, estimates suggest it could fall to around 30-35% for the combined CPI, aligning more closely with consumption patterns observed in developed and even some emerging economies. This reduction will be compensated by an increased weighting for other categories, particularly services, health, education, transport, and communication. These categories reflect the growing disposable incomes and changing lifestyle aspirations of a significant portion of the Indian populace.
Alongside the revised weights, a new base year is expected to be adopted. The HCES 2022-23 data makes this fiscal year a strong candidate for the new base year, replacing the current 2012. A newer base year ensures that the basket of goods and services, as well as their relative importance, reflects the most recent economic realities, incorporating new products and services that have become commonplace since the last revision.
Impact: Ripple Effects Across the Economy
The re-weighting of the CPI is not merely a statistical exercise; it carries profound implications for various stakeholders across the Indian economy, from policymakers to the common consumer.

Monetary Policy Implications
The Reserve Bank of India (RBI) operates under an inflation-targeting framework, using the CPI as its primary guide. A reduced food weight means that headline inflation will become less volatile and less susceptible to seasonal or supply-driven food price shocks. This could provide the RBI with a clearer picture of underlying demand-side inflation, allowing for more stable and predictable monetary policy decisions. For instance, temporary spikes in vegetable prices might have a diminished impact on the overall CPI, potentially reducing the urgency for interest rate hikes. Conversely, persistent non-food inflation might become more apparent, necessitating a more focused policy response.
Socio-Economic Repercussions
For the government, the new CPI series will influence various policy decisions, including budgetary allocations, wage indexation for government employees (Dearness Allowance), and the design of social welfare schemes. A CPI that more accurately reflects contemporary expenditure patterns can lead to more targeted and effective policies. However, there is a nuanced debate regarding the impact on lower-income households. While the national average shows a decline in food expenditure share, for the poorest segments, food still constitutes a large portion of their budget. Critics argue that a lower food weight might understate the real inflation experienced by these vulnerable groups, potentially impacting their purchasing power and living standards if policies are solely based on the new aggregate index.
Impact on Businesses and Markets
Businesses will also need to adapt to the new inflation landscape. Investment decisions, pricing strategies, and wage negotiations often consider inflation trends. A more stable and representative CPI could lead to greater certainty in long-term planning. Financial markets, particularly bond markets, are highly sensitive to inflation data. A CPI less prone to erratic swings could foster greater stability and potentially influence yields and investment flows. Economists and analysts will gain a more robust tool for forecasting and understanding India's economic trajectory, allowing for better identification of structural inflationary pressures versus transient ones.
What Next: The Roadmap to Implementation
The unveiling of the new CPI series is a multi-stage process involving rigorous data analysis, expert consultations, and official announcements. The recent release of the HCES 2022-23 summary findings is the first critical step, providing the foundational data for the re-weighting.
Roadmap to Implementation
The NSO is currently in the process of thoroughly analyzing the HCES data to finalize the new consumption basket and assign appropriate weights. This involves detailed classification of goods and services, ensuring comprehensive coverage and accurate representation. Following this, the NSO will likely engage in internal reviews and expert consultations to validate the methodology and proposed changes.

An official announcement detailing the new base year, the revised weighting structure, and the launch date for the new series is anticipated in the coming months. While specific timelines are subject to governmental procedures, the push for a more modern and representative inflation measure suggests an expedited process. Once launched, the new CPI series will be published regularly, providing the public and policymakers with an updated and more accurate gauge of price changes in the Indian economy, reflecting its continued growth and evolving consumer behaviour.
