On 7 July 2026, the Ministry of Statistics and Programme Implementation (MoSPI) released the Report of the Technical Advisory Committee on the Index of Services Production (ISP), with a proposed base year of 2024-25. The ISP will do for services what the long-running Index of Industrial Production (IIP) does for industry: provide, for the first time, a comprehensive monthly measure of short-term movements in India's formal services economy. Since services contribute nearly 53% of India's Gross Value Added (GVA), this is a genuinely significant upgrade to the country's statistical system — and a very examinable one for CDS/OTA aspirants who need to know how India actually measures its economy.
The news, decoded
The testable essentials first:
- What: a new Index of Services Production (ISP) — a high-frequency (monthly) indicator for the services sector.
- Who: compiled by MoSPI, on the recommendation of a Technical Advisory Committee (TAC).
- Base year: 2024-25 (a fresh, recent base — important, because a modern base keeps the index representative).
- Why it matters: services are more than 50% of GVA, yet India had no monthly production index for them — a large blind spot.
- Data source: Goods and Services Tax (GST) returns, shared in aggregated form (MoSPI does not access unit-level taxpayer data).
Why a services index was missing — and why that mattered
For decades, India could track its industrial heartbeat every month through the IIP, but it had no equivalent monthly pulse for services — trade, transport, telecom, finance, real estate, professional services and the rest. That is a strange gap for an economy where services are the single largest sector. Policymakers, the RBI and investors were effectively flying with one instrument: they saw monthly factory output but had to wait for quarterly GDP/GVA estimates to gauge the far bigger services sector.
The ISP fills that gap. By giving a monthly reading of services output, it lets the government spot slowdowns or surges in real time and complements the IIP, so that together the two indices cover the bulk of the formal economy at monthly frequency. This is a story about better economic navigation, and it connects naturally to how national income is built up, covered in the CDS/OTA notes on the economy.
The clever part: using GST data
The ISP's methodology is where the real innovation — and a likely exam point — lies. The committee's insight is that the GST system has transformed India's statistical landscape:
- Every month, millions of businesses file GST returns reporting their outward supplies (sales). That is a vast, timely, ready-made record of economic activity.
- For many market services, output and consumption happen simultaneously (a haircut, a phone call, a consultancy hour), so outward supplies closely track actual production.
- By deflating GST-based outward supplies with suitable price deflators, statisticians can estimate real (inflation-adjusted) changes in services output monthly.
- Because GST data is already collected for tax purposes, the ISP imposes no extra reporting burden on businesses — a major administrative virtue.
Crucially, MoSPI clarified that it uses only aggregated GST data and neither has nor needs unit-level (individual taxpayer) data — a deliberate safeguard for confidentiality. This is a model example of using existing administrative data for statistics, the kind of governance-and-economy crossover that rewards candidates who follow the CDS/OTA daily current affairs.
What the ISP will — and won't — capture
Good statistics come with honest caveats, and the committee flagged the coverage limits, which make sharp MCQ fodder. GST-based data covers most market-based services well: trade, accommodation, food services, telecommunications, professional services, real estate and administrative support. But several services are exempt from GST or otherwise outside the net, and so are harder to capture, including:
- Health and education services,
- a large chunk of railways,
- individual life and health insurance,
- non-AC public transport, and
- transport of essential goods.
So the ISP is a powerful formal, market-services gauge, not a total measure of every service in the economy. Knowing this boundary is exactly the nuance an examiner uses to separate rote-learners from those who understand the instrument.
Fitting the ISP into India's statistical toolkit
To place the ISP correctly, line up the family of indicators the exam keeps testing:
- GDP / GVA — the comprehensive measure of output, released quarterly and annually by MoSPI. GVA is output measured at basic prices (GDP = GVA + net taxes on products). Services are ~53% of GVA.
- IIP (Index of Industrial Production) — a monthly volume index of industrial output (mining, manufacturing, electricity), base year 2011-12, compiled by MoSPI.
- ISP (Index of Services Production) — the new monthly index for services, base year 2024-25.
- CPI / WPI — the price indices (consumer and wholesale) that measure inflation, distinct from the production indices above.
The one-line map: GDP/GVA = the whole picture (quarterly); IIP = industry monthly; ISP = services monthly; CPI/WPI = prices. This ISP launch also rhymes with the ongoing base-year revisions across India's indices — a theme you can revise alongside the notes on inflation and price indices.
Why base years and high-frequency data matter
Two conceptual takeaways deserve a line each, because they generalise beyond this news:
- Base-year updates keep an index honest. An index compares today's output to a base period. If the base is old (say 2011-12), the basket of goods/services and their weights no longer reflect the modern economy, so the index drifts from reality. Choosing 2024-25 as the ISP base means it starts life representative.
- High-frequency indicators enable timely policy. Monthly data lets the RBI and government respond to shocks quickly instead of discovering a slowdown two quarters late. In a services-led economy, a monthly services index is the missing piece for real-time macro management.
Exam relevance in one paragraph
For CDS/OTA GK, hold onto: ISP = MoSPI's new monthly index for services (base 2024-25), built from aggregated GST data, complementing the IIP (base 2011-12); services ≈ 53% of GVA. For the essay/interview, the larger argument is that India is upgrading its statistical infrastructure to match a services-dominated economy — a strong example of evidence-based governance.

📋 How this gets asked (PYQ pattern)
Economic-measurement questions are a steady CDS/OTA economy set. The dependable framings are "which body releases the IIP/GVA" (MoSPI), "IIP covers which sectors" (mining, manufacturing, electricity), and base-year identification (IIP = 2011-12). A common trap swaps production indices (IIP/ISP) with price indices (CPI/WPI), or confuses GVA with GDP. The fresh 2026 hook is the ISP (base 2024-25) built on GST data — perfect for "which is the new services index / what base year / which body" items. We flag the pattern rather than quoting any exact past question.
