New Delhi: India on Thursday introduced a new series of its Consumer Price Index (CPI), the benchmark that tracks retail inflation. The change will improve the quality of data used in formulating monetary and fiscal policies, according to Chief Economic Advisor V Anantha Nageswaran.
The new index will reflect changes in spending patterns since the last overhaul done more than a decade ago.
CPI under the new series came in at 2.75 per cent for January, according to data released by the Ministry of Statistics and Programme Implementation.
It updates the base year to 2024 from 2012 while coverage has widened to 358 items from 299 – including 308 goods and 50 services – with price data now collected from 1,465 rural and 1,395 urban markets, as well as 12 online marketplaces. The new CPI series expands classification from six to 12 groups, adding several standalone categories to provide greater granularity.
The weight of food and beverages has been reduced to 36.75 per cent from 45.86 per cent, potentially lowering headline volatility. Housing, now expanded to include utilities, carries a 17.67 per cent weight. Paan, tobacco and intoxicants rose to 2.99 per cent, while clothing and footwear fell to 2.38 per cent.
Index values under the new series are available from January 2025, making year-on-year inflation comparable only from January 2026. A linking factor allows back-calculation to 2013.
Newly delineated groups include furnishings, household equipment and routine household maintenance (4.47 per cent weight), health (6.1 per cent), transport (8.8 per cent), information and communication (3.61 per cent), recreation, sports and culture (1.52 per cent), education services (3.33 per cent), restaurants and accommodation services (3.35 per cent), and personal care, social protection and miscellaneous goods and services (5.04 per cent).
At the item level, obsolete products have been dropped from the basket, while categories have been rationalised and reclassified to align with current consumption patterns under the 2024 base and COICOP framework, improving comparability and relevance.
The National Statistics Office (NSO) under the Ministry of Statistics & Programme Implementation (MoSPI) on Thursday released the new Consumer Price Index (CPI) with Base 2024=100.
The new series has captured more goods and services items, and excluded those which are not consumed presently. Weights of different item groups have been recalibrated based on the Household Consumption Expenditure Survey (HCES) 2023-24.
“Since the CPI basket is now aligned with recent expenditure data, the inflation signals derived from this will be more closely matched with the economic conditions. This improves the information basis for calibrating monetary and fiscal policy,” Nageswaran told reporters at a press conference on the new CPI series.
He said that the new series, with wider coverage of services and digital markets, provides policymakers with a more up-to-date basis for assessing real incomes, consumption trends, and purchasing power.
The Reserve Bank of India (RBI) factors in the retail inflation while arriving at its bi-monthly monetary policy decision.
He said if CPI volatility declines, fiscal expenditure, DA fixation, and index bonds, which are linked to CPI, would become more stable, predictable and reliable.
The CEA said the proportion of weights assigned to the food basket has come down from 45.86 in CPI 2012 to 36.75 in the new series.
It also reflects the reallocation of certain items to other categories, such as restaurants and services.
“At the macro level, this reflects a progressive diversification of expenditure towards health, education, mobility, and connectivity, which is what you would expect to see from an economy which is seeing rising incomes and rising living standards,” Nageswaran said.
He added that lower weightage for the otherwise volatile group of food and beverages may make the headline inflation also less volatile.
Such rebalancing, he said, is typically associated with income growth, productivity gains, and improving living standards.
The revised basket also highlights the increasing role of services in consumption, he added.
“This brings consumption measurement closer to the evolving structure of output and employment, where services account for a rising share of economic activity,” he said.
The new series also recognises the growing role of digital channels in price formation and would help in better distinguishing urban and rural dynamics of inflation at the state level, and the subclass as well as item level, Nageswaran said.
He said if CPI volatility declines, fiscal expenditure, DA fixation, index bonds, et cetera, which are linked to CPI, would become more stable, predictable and reliable.
The new CPI series and upcoming GDP and IIP with a new base year will align Indian data with the best in the world, he added.
