Index of Services Production (ISP)
Why in News?
The Index of Services Production (ISP) is in the news because the Ministry of Statistics and Programme Implementation (MoSPI) has finalized its technical framework, with the official trial monthly series scheduled for debut on July 14, 2026.
Objective & Structural Alignment
- A specialized Technical Advisory Committee (TAC), led by NITI Aayog Distinguished Fellow Debjani Ghosh, recommended a phased rollout beginning with trial indices.
- The Counterpart to IIP: Serves as the service sector's direct equivalent to the long-standing Index of Industrial Production (IIP) used for manufacturing.
- Statistical Gap Bridging: The services sector contributes nearly 53% to India’s Gross Value Added (GVA), but previously lacked high-frequency monthly tracking, relying instead on lagged quarterly GVA datasets.
- Base Year Designated: Formulated with 2024–25 as its baseline statistical year.
- Reporting Frequency: Will be published monthly by the National Statistical Office (NSO) with an operational lag of 60 days from the end of the reference month.
Data Sources and Methodology
- GSTN Reliance: Driven primarily by real data pulled from the Goods and Services Tax Network (GSTN) database on outward taxable supplies.
- Administrative Inputs: Supplemented with operational data from key regulatory bodies, including Indian Railways, civil aviation, banking, and insurance regulators.
- Survey Baseline: Uses structural data points gathered via the new Annual Survey of Incorporated Services Sector Enterprises (ASISSE).
- Inflation Deflators: Volumetric adjustments will rely on the non-food Consumer Price Index (CPI) and tailored, sector-specific CPI trackers.
Sectoral Scope and Exclusions
- Initial Sub-sectors Included: Tracks over 40 formal sub-sectors, including wholesale/retail trade, transport, telecom, hospitality, real estate, professional services, and entertainment.
- Temporary Exclusions: Health and education services are excluded for now, pending deeper baseline data incorporation from ASISSE.
- Structural Omissions: Excludes the informal services sector due to existing data gaps.
- Non-Market Omissions: Excludes non-market public segments like national defence, public administration, social work, and central banking.
- Policy Guidance: Arms policymakers, economists, and corporate entities with actionable, high-frequency data for better business cycle analysis.
- Pricing Transformations: Integrates structurally with India's long-term macro transition away from the Wholesale Price Index (WPI) toward a modern Producer Price Index (PPI) framework.
