Price pressures: On new series of Consumer Price Index, inflation
Context
India has introduced a new Consumer Price Index (CPI) series with base year 2024, replacing the earlier base year of 2012. The revised CPI reflects updated consumption patterns using the 2023–24 Household Consumption Expenditure Survey and a redesigned basket of goods and services.
The first inflation reading under the new CPI showed retail inflation at about 2.75% in January 2026, while it rose to 3.21% in February 2026, mainly due to food price increases.
What is the Consumer Price Index (CPI)?
The Consumer Price Index (CPI) measures the average change in prices of goods and services consumed by households. It is the primary indicator used by the Reserve Bank of India for monetary policy under the inflation-targeting framework.
Key uses:
- Measures retail inflation
- Guides interest rate decisions
- Influences government welfare schemes, wages, and pensions
Key Changes in the New CPI Series (Base Year 2024)
1. Change in Base Year
- Old base year: 2012
- New base year: 2024
This reflects current consumption behaviour and economic changes.
2. Updated Consumption Basket
- Items increased from 299 to 358.
- Includes more services and digital consumption items such as online subscriptions and air travel.
3. Reduced Weight of Food
- Food weight reduced from 45.86% → about 36.75%.
Reason:
- As incomes rise, households spend less proportionally on food and more on services.
4. Expanded Coverage
- Prices collected from more rural and urban markets.
- Inclusion of e-commerce prices and digital services.
5. Adoption of International Classification
- Uses COICOP (Classification of Individual Consumption by Purpose) for better global comparability.
4. Why the New CPI Series Matters
(a) Reflects Changing Consumption Patterns
The old CPI was based on the 2011–12 consumption survey, which no longer captured modern spending habits such as:
- digital services
- transport
- healthcare
- communication services.
(b) Better Monetary Policy Signals
With updated weights and improved data, inflation readings become more reliable for policy decisions by the Reserve Bank of India.
(c) Less Volatility in Inflation
Lower food weight may reduce sudden spikes in headline inflation, since food prices fluctuate heavily.
(d) Improved Statistical Credibility
Regular updates of economic indicators improve investor confidence and international credibility.
Concerns and Challenges
1. Comparability Issues
Inflation numbers from the new series cannot be directly compared with the old series, which may create confusion in economic analysis.
2. Risk of Underestimating Food Inflation
Food prices still affect the poorest households disproportionately, and reducing its weight may mask real price pressures.
3. Data Collection Challenges
Incorporating digital prices, services, and diverse markets requires robust statistical capacity.
4. Regional Variations
Different states experience varying inflation levels, which may not be fully captured in national averages.
Way Forward
- Regular revision of base years (every 3–5 years).
- Strengthen price data collection mechanisms including digital markets.
- Improve state-level inflation monitoring.
- Complement CPI with food inflation and rural inflation indicators to protect vulnerable groups.
Conclusion
The new CPI series represents an important statistical modernization of India’s inflation measurement system. By updating the consumption basket and reducing the dominance of food prices, it offers a more accurate picture of contemporary spending patterns. However, policymakers must ensure that the revised index does not overlook price pressures affecting poorer households, as inflation remains a crucial determinant of economic stability and social welfare.
