The Ministry of Statistics & Programme Implementation (MoSPI) released the sub-sectoral trial Index of Services Production (ISP) for June 2026, covering 19 broad service sub-sectors on the 2024-25 base year.
Eighteen of the 19 sub-sectors grew over June 2025 and eight recorded double-digit growth; Real Estate led at 24.7 per cent, followed by Retail Trade (18.0 per cent), Wholesale Trade (15.1 per cent), Administrative and Support Services (14.4 per cent) and IT and Computer Related Services (13.5 per cent).
Air Transport was the only sub-sector to contract, falling 6.0 per cent with an index level of 91.2 — below its 2024-25 base of 100.
The indices remain experimental: MoSPI is publishing a trial series to test data quality and resilience and to collect user feedback before regular publication, and the Railways, Banking and Insurance indices rest on provisional monthly data that will be revised annually.
ISP data is hosted on MoSPI's eSankhyiki portal alongside the ministry's other releases.
A Laspeyres index measures how much the quantity of output has changed relative to a base period, holding the weights of the base period fixed. For the ISP, those weights come from each sub-sector's share of Gross Value Added in 2024-25 as published in the National Accounts Statistics, and the sub-sectoral indices are compiled at the 2-digit level of the National Industrial Classification (NIC) 2025. Because the weights are frozen at the base year, the index isolates changes in the volume of services produced rather than changes in their prices — which is why the base year has to be revised periodically as the structure of the economy shifts. The same fixed-weight logic underlies the Index of Industrial Production.
Simple Analogy: Think of a shopping basket whose contents were fixed in 2024-25. Each month you check only how much of that same basket got produced, never changing what is in it. When the economy's real basket has drifted too far from the frozen one, you rebase — which is exactly why the IIP moved from a 2011-12 basket to a 2022-23 one.
| Aspect | Index of Services Production (ISP) | Index of Industrial Production (IIP) |
|---|---|---|
| What it measures | Volume of output of the services sector | Volume of output of the industrial sector |
| Base year | 2024-25 | 2022-23 (revised from 2011-12) |
| Sectors covered | 19 broad service sub-sectors in the trial series, about 60% of service activities | Three sectors — Mining, Manufacturing and Electricity |
| Item/sector basket | 2-digit NIC 2025 sub-sectors, weighted by GVA shares | 1,042 items mapped to 463 item groups, against 839 items in 407 groups in the 2011-12 series |
| Principal data source | Aggregated GST data, plus administrative datasets for non-GST services | Returns from factories, mines and power utilities routed through source agencies |
| Status | Trial/experimental series since 14 July 2026 | Regular official series, published monthly for decades |
| Compiled by | National Statistical Office, MoSPI | National Statistical Office, MoSPI |
The nodal ministry for India's official statistics — national income, industrial production, prices, household consumption and now the ISP. It also runs the eSankhyiki data platform on which ISP data is published.
The apex agency that compiles India's official statistics, including the ISP, the IIP, GDP estimates and the CPI. It is an office within MoSPI, not a statutory body.
The expert committee that designed the ISP framework. Constituted in May 2025, it recommended a phased rollout — trial indices first, then regular publication — so the methodology could be validated against quarterly and annual datasets and stakeholder feedback collected. Its report was released on 7 July 2026, a week before the first trial index.
The ISP sits at the end of a wider rebasing exercise. The IIP moved to a 2022-23 base, and MoSPI's National Accounts Statistics 2026 shifted the national accounts themselves to the 2022-23 base, bringing in a new output Producer Price Index and a Banking Services Price Index. The ISP's own 2024-25 base is more recent because it is a brand-new series with no back history to preserve.
The ISP is the clearest case so far of tax administration data being repurposed as economic statistics. It also explains a quirk of the series — the sharp March 2026 spike across several sub-sectors reflects the financial-year-end surge in billing that GST data captures.
Air Transport is the only ISP sub-sector below its 2024-25 base, at 91.2 in June 2026. Its annexure series shows the index above 110 through the winter months of 2025-26 before falling away from April 2026 — a seasonal pattern worth noting when a single month's index is read as a growth signal.
Two large service sectors sit outside the trial index because they sit largely outside GST. MoSPI proposes to add them once the Annual Survey of Incorporated Services Sector Enterprises (ASISSE) yields usable benchmarks — which is why the trial index covers only about 60 per cent of services.
