India's ISP debut: 14 of 19 services sub-sectors log double-digit growth in April 2026
Synopsis
Key Takeaways
The Ministry of Statistics and Programme Implementation (MoSPI) on Tuesday, 14 July 2026 released India's first sub-sectoral Trial Index of Services Production (ISP), with base year 2024-25, revealing that 14 of 19 tracked sub-sectors posted double-digit growth in April 2026 compared to April 2025. Nearly all categories recorded positive growth, and the 19 sub-sectors together account for roughly 60 per cent of India's services sector.
Top-Performing Sub-Sectors
Accommodation and Food led the pack with a remarkable 37.2 per cent expansion, followed by Retail Trade at 30.8 per cent, Administrative and Support Services at 28.7 per cent, and Real Estate at 27.7 per cent. These figures reflect broad-based momentum across consumer-facing and enterprise services segments in the first month of the new financial year.
What the ISP Measures and How
The ISP tracks short-term movements in India's formal services sector on a monthly basis — a first for the country's statistical architecture. Data is sourced primarily from GST filings and administrative records. Administrative and secondary data feeds into sub-sectors such as Air Transport, Railway Transport, Water Transport (Freight), Banking, and Insurance, while GST data underpins the remaining sub-sectors including IT and computer-related services, Telecommunications, Professional and Scientific Services, and Arts, Entertainment and Recreation.
For price deflation, the index uses the Wholesale Price Index (WPI) for Wholesale Trade and sub-sector-specific or proxy Consumer Price Index (CPI) measures for others. Where no suitable mapping exists, CPI-Services has been applied as the deflator.
Why This Milestone Matters
India's services sector contributes more than half of the country's total economic activity, yet until now lacked a dedicated, high-frequency production index. The ISP fills a critical data gap, enabling policymakers, investors, and researchers to track services-sector momentum in near real time rather than relying solely on quarterly GDP estimates. Notably, this release follows the constitution of the Technical Advisory Committee on ISP (TAC-ISP) in May 2025, which provided conceptual and methodological guidance, drawing on expertise from academia, industry associations, and concerned ministries.
The index is currently being published on an experimental basis — a trial series designed to let MoSPI assess data quality, test resilience, and gather stakeholder feedback before a full rollout.
Scope, Limitations, and What Comes Next
Because the ISP relies on GST and administrative data, it covers only formal-sector enterprises. Sub-sectors dominated by core government activities, non-market activities, or the informal economy fall outside its current scope. MoSPI has indicated that an overall ISP — aggregating across all services — will be released only after the stability and resilience of the sub-sectoral indices have been established and overall coverage improved. The trial series will continue to evolve as feedback is incorporated and data quality benchmarks are met.
