Retail inflation at 2.75% in new Consumer Price Index with 2024 as the base year

1. At a Glance

• MoSPI released the revised Consumer Price Index (CPI) with 2024 as the new base year on 12 February 2026, replacing the decade-old 2012 series. [1]
• Retail inflation for January 2026 stood at 2.75% under the new series — the first data point on the revised base. [1]
• The rebasing reflects a structural overhaul: items basket, weights, markets covered, and data sources have all been significantly updated. [1]
• Highly relevant to GS-III (Indian Economy) and a perennial source of Prelims MCQs on price indices, base-year revisions, and inflation measurement.

2. Why in the News

• On 12 February 2026, MoSPI Secretary Saurabh Garg and Chief Economic Adviser V. Anantha Nageswaran jointly unveiled the new CPI series in New Delhi. [1]
• The release generated policy attention because the 2.75% print (January 2026) under the new series differs from readings under the old 2012-base series — historical comparison is not yet possible as this is the first data release. [1]
• The revision is particularly significant given the RBI's monetary policy framework (inflation targeting) uses CPI as its benchmark; a rebased index can affect perceived inflation trajectory.

3. Background & Evolution

Predecessors: CPI (Industrial Workers) — base 2016; CPI (Agricultural Labourers) — base 1986-87. The combined CPI (Rural + Urban + Combined) released by MoSPI is the headline measure used by RBI.

4. Core Static Facts

Implementing Body

• Ministry of Statistics and Programme Implementation (MoSPI) — nodal ministry for CPI releases. [1]
• Field data collected by National Statistical Office (NSO) under MoSPI.

Basket & Weights — Old vs. New Series

[1]

Weight Revision Source

• Weights revised using Household Consumption Expenditure Survey (HCES) 2023-24 — first comprehensive HCES since 2011-12. [1]

Key Definitions

• Base Year: Reference period against which price changes are measured; index = 100 in base year.
• CPI: Measures change in retail prices of a fixed basket of goods and services consumed by households.
• Inflation Targeting Band: 4% ± 2% (i.e., 2–6%) under the RBI Act, 1934 (Section 45ZA–45ZB) as amended in 2016.

5. Multi-Dimensional Analysis

Economic

• 2.75% retail inflation (January 2026) under the new series suggests price pressures are well within the RBI's tolerance band of 2–6%. [1]
• Rebasing corrects substitution bias and new-goods bias — households had shifted consumption patterns significantly since 2012; old weights over-represented food relative to services.
• Inclusion of online marketplace prices reflects the growing share of e-commerce in household spending; may introduce more competitive (lower) price signals into the index.
• Weight revision in favour of services (50 items vs 40) captures India's structural shift toward a services-led economy, potentially altering measured inflation dynamics.

Governance / Administrative

• Release jointly flagged by MoSPI Secretary and Chief Economic Adviser — signals high-level policy ownership. [1]
• Historical comparison not yet possible — a critical governance gap; RBI and policymakers must operate with a break in series until a longer back-series is constructed.
• Expanded market coverage (rural: +284 markets; urban: +281 markets) improves geographic representativeness and reduces sampling error. [1]

Legal / Constitutional

• RBI's inflation mandate is statutory under RBI Act, 1934 (Section 45ZA), amended by Finance Act 2016; Government notifies the inflation target in consultation with RBI.
• The Monetary Policy Committee (MPC) — 6 members, 3 from RBI + 3 external — is accountable to Parliament if inflation breaches the band for 3 consecutive quarters.

Social

• HCES 2023-24 data reveals shifts in consumption: services basket expansion (40→50) reflects rising health, education, and digital service expenditures among households, especially urban middle class.
• More accurate weights ensure that food inflation (which disproportionately affects the poor) is correctly measured; over-weighting food would have inflated headline CPI artificially.

Historical

• Base-year revisions in India have historically coincided with quinquennial consumption surveys; the gap between 2012 (NSSO 2011-12) and 2024 (HCES 2023-24) was unusually long (~12 years) due to postponement of the 2017-18 NSSO survey results.
• The scrapping of NSSO 2017-18 consumer expenditure data by the government (2019) and the subsequent HCES 2023-24 make this revision particularly consequential.

6. Recent Developments (Last 12–18 Months)

• 2023-24: MoSPI conducts HCES 2023-24 — comprehensive household consumption data used as basis for new CPI weights. [1]
• February 12, 2026: MoSPI releases CPI new series (base year 2024); first data point shows January 2026 inflation at 2.75%. [1]
• February 12, 2026: CEA V. Anantha Nageswaran states: "The economy has undergone a significant transformation in the last decade... consumption behaviour, market structures, and compositions of household expenditure have evolved." [1]
• 12 online marketplaces incorporated as a new data-collection category for the first time in any CPI series in India. [1]
• RBI's MPC had been navigating a declining inflation trajectory under the old series in late 2025; the new series reading of 2.75% will need calibration before policy conclusions can be drawn.

7. Prelims Hooks

1. The new CPI series released in February 2026 has 2024 as its base year, replacing the 2012 base year series. [1]
2. The total number of items in the new CPI basket is 358, up from 299 in the old series. [1]
3. Goods in the basket increased from 259 to 308; Services from 40 to 50. [1]
4. The new series covers 1,465 rural markets (up from 1,181) and 1,395 urban markets (up from 1,114). [1]
5. A new category of 12 online marketplaces has been added as a data-collection source — a first for Indian CPI. [1]
6. Weights in the new series are based on the Household Consumption Expenditure Survey (HCES) 2023-24. [1]
7. Retail inflation in January 2026 under the new CPI series was recorded at 2.75%. [1]
8. The new CPI data was released by MoSPI (Ministry of Statistics and Programme Implementation). [1]
9. MoSPI Secretary at the time of release: Saurabh Garg; Chief Economic Adviser: V. Anantha Nageswaran. [1]
10. RBI's inflation target under the RBI Act, 1934 (Section 45ZA) is 4% with ± 2% tolerance band — measured using CPI.
11. The previous HCES before 2023-24 was conducted in 2011-12 (NSSO); the 2017-18 survey results were officially withheld.
12. The CPI is released monthly by MoSPI with a lag of approximately 12 days after the reference month ends.
13. India follows a combined CPI (Rural + Urban) as the headline inflation measure for monetary policy, not CPI-IW (which is for wage indexation).

10. Common Errors / Trap Areas

1. Wrong ministry: CPI is released by MoSPI, not the Ministry of Finance or RBI. RBI uses CPI; it does not produce it.
2. Confusing CPI with CPI-IW: The CPI-IW (Industrial Workers) — maintained by the Labour Bureau under the Ministry of Labour — has a different base year (2016) and is used for wage/DA calculations, not monetary policy. Do not conflate with the headline CPI.
3. Old vs. new item count: A classic trap — old series had 299 items (not 300); new series has 358 (not 350 or 360). [1]
4. Inflation target confusion: The target is 4%, not 6%. The band is ±2% (floor 2%, ceiling 6%). Stating the target as 6% is a common error.
5. "Historical comparison is possible": The article explicitly states that as this is the first data release under the new series, historical comparison is NOT yet possible. Aspirants must not assume continuity with old series readings. [1]
