Q. Examine the significance of incorporating e-commerce price data and HCES 2023-24 in India's revised CPI series. (15 marks, 250-350 words)

The Consumer Price Index, India's anchor for flexible inflation targeting, was rebased by MoSPI from 2012=100 to 2024=100, with the revised series released on 12 February 2026 [1]. Two changes define its credibility: weights drawn from the Household Consumption Expenditure Survey (HCES) 2023-24, and first-ever capture of online market prices.

Significance of HCES 2023-24 as the weight source - Restores representativeness: weights earlier reflected 2011-12 consumption; a decade of urbanisation, income growth and services expansion had made those shares stale [2]. - Corrects composition bias: updated shares reduce under-weighting of services and digital spending, so the index tracks what households actually buy [2]. - Enables basket modernisation: the All-India basket expanded to 358 items, including new-economy consumption such as streaming services [2]. - Improves policy inputs: since the Monetary Policy Committee targets CPI, a mis-weighted basket transmits directly into distorted interest-rate decisions [2].

Significance of e-commerce price data - First-of-its-kind coverage: 12 online markets across 12 towns of population above 25 lakh now feed price data [1]. - Captures a real purchase channel: platform-based retail prices often diverge from physical-market quotations; ignoring them understates or overstates urban price experience [1]. - Complements a widened field network: 1,465 rural and 1,395 urban markets across 434 towns deepen granularity alongside the online component [1].

Wider gains and limits - Adoption of the COICOP 2018 classification aligns Indian CPI with international standards, aiding cross-country comparison [2]. - Yet a 12-year revision gap, thin online coverage confined to the largest towns, and a break in comparability with the old series constrain immediate analytical use [2].

The revision converts CPI from a dated proxy into a closer mirror of contemporary consumption, strengthening both monetary policy and welfare indexation. Shortening the revision cycle and progressively widening online price capture would make the gain durable, advancing the credibility of official statistics that sound macroeconomic governance rests upon.
