MoSPI will launch the Index of Services Production (ISP) in July 2026 to provide monthly data on India's formal services sector growth. Currently, India lacks a high-frequency services output index, unlike manufacturing which has the Index of Industrial Production (IIP). The ISP aims to fill this critical data gap, covering sectors like IT, finance, trade, and transport, enabling better GDP nowcasting, policy formulation, and timely economic monitoring by RBI and government planners.

India's services sector contributes approximately 55–57% of GDP and employs hundreds of millions, yet policymakers have historically lacked a timely, monthly output tracker for it. The Index of Industrial Production (IIP), released monthly by MoSPI, tracks manufacturing, mining, and electricity — but services have no equivalent. This means RBI's monetary policy committee, finance ministry budget planners, and international institutions like IMF rely on quarterly GDP estimates or proxy indicators like PMI Services (a private survey) to gauge services momentum. The ISP changes this fundamentally. By compiling output data from formal services enterprises monthly, it will allow 'nowcasting' — estimating current-quarter GDP before official figures arrive. This is especially significant because India's services-led growth model means manufacturing-centric IIP often understates economic momentum. For UPSC, the ISP fits squarely into GS3 themes: national income measurement, data governance, statistical infrastructure, and economic survey discussions. Examiners can link ISP to the Base Year revision debate (currently 2011-12), the shift to enterprise surveys, and India's compliance with IMF data standards (SDDS Plus). The ISP also has federal implications — state-level services data could eventually inform devolution and GSDP calculations, connecting to Finance Commission methodology.
