Q. Why does India need a high-frequency Index of Services Production despite the services sector already being captured in GDP estimates? (15 marks, 250-350 words)

Services account for nearly 53% of India's Gross Value Added, yet until the Index of Services Production (ISP) with base year 2024-25, India had no monthly output tracker for services comparable to the IIP for industry [1]. GDP captures services, but not at the frequency or granularity policy now demands.

Gaps that GDP estimates leave - Frequency and lag: GDP/GVA are quarterly and lagged; monetary, fiscal and trade decisions need monthly signals. ISP will be monthly with about a 60-day lag [1]. - Value versus volume: GVA aggregates are value-based; ISP is a Laspeyres volume index using WPI and CPI-based deflators, isolating real output from price change [1]. - Statistical asymmetry: industry has been tracked by the IIP for decades while the largest sector stayed a high-frequency blind spot — ISP is explicitly its services counterpart [1]. - Granularity: ISP gives sector-wise indices at the 2-digit NIC 2025 level, which headline GVA cannot offer [1].

What the new index delivers - Coverage built from an analysis of over 40 services sub-sectors — trade, transport, banking, insurance, communication, hotels, real estate and professional services [2]. - The first trial index (April 2026) spans 19 sub-sectors, roughly 60% of the services sector [1].

Data convergence as the enabling reform - ISP draws on aggregated GST data, administrative datasets of railways, aviation, banking and insurance, and survey data for health and education — avoiding a costly fresh survey and reducing respondent burden [2]. - Confidentiality is protected: MoSPI uses only aggregated, not unit-level, GST data [2]. - Design credibility rests on the TAC-ISP (constituted May 2025, chaired by Ms. Debjani Ghosh, NITI Aayog) and an Approach Paper opened to public consultation [3].

ISP therefore converts an annual-quarterly picture into a continuous pulse of the services economy. Extending coverage beyond the formal sector and shortening the release lag should be the next steps, so that India's statistical system matches the weight services carry in its growth story.
