Q. Discuss the significance of the newly launched Index of Services Production (ISP) in strengthening India's macroeconomic statistical architecture. What are its current limitations? (15 marks, 250 words)

Launched by MoSPI on 14 July 2026 with base year 2024-25, the Index of Services Production (ISP) is a monthly indicator of real output in the formal services sector — the long-missing counterpart to the Index of Industrial Production (IIP) [1]. It closes a critical gap: services have contributed over 50% of India's GVA since 2013-14, yet lacked a high-frequency output gauge [2].

Significance for statistical architecture - Fills a data void: provides real-time tracking of services output, complementing IIP (industry) and GDP estimates for a fuller macro picture [2]. - Sharper policy calibration: high-frequency signals aid monetary and fiscal fine-tuning in a services-led economy [2]. - Modern data architecture: blends administrative data, GST returns, and the ASISSE survey, advancing MoSPI's shift to alternative/tax data [2]. - Methodological rigour: a fixed-weight Laspeyres volume index with GVA-based weights; base year harmonised with the new CPI (2024) for deflator consistency [2]. - Credibility-first rollout: phased trial → sub-sectoral → eventual overall index limits revision-driven credibility loss [1].

Current limitations - Partial coverage: only 19 sub-sectors (~60%) of the formal sector; no combined "overall ISP" yet [1]. - Informal blind spot: informal services — a large share of services employment — remain excluded, denting representativeness [2]. - Key exclusions: public administration and government health/education omitted [2]. - Reporting lag: ~60-day lag dilutes real-time utility [2].

As the index stabilises and widens toward informal coverage, ISP can become a cornerstone of evidence-based, IIP-parallel economic monitoring, strengthening the credibility of India's official statistics.
