1.India's CPI basket has been revised to a 2024 base year, moving from 6 to 12 categories aligned with COICOP 2018, using updated HCES data.

2.The new weights reduce food's influence and increase the weight of housing and services, making state-level inflation reflect structural consumption differences, especially in services-intensive states.

3.For the RBI, this refined CPI helps distinguish short-term food price volatility from persistent service inflation, a critical input for monetary policy decisions.

The Big Picture

India's Consumer Price Index (CPI) has been updated to a 2024 base year, reorganizing the consumption basket into 12 categories as per COICOP 2018. This revision, based on the latest Household Consumption Expenditure Survey (HCES), reduces food weight and increases housing and services weight, providing the RBI with a clearer signal to differentiate between transient food inflation and persistent service price pressures.
