Index of Services Production (ISP)
Why in News?
The Ministry of Statistics and Programme Implementation (MoSPI) released India’s first trial Index of Services Production (ISP) for April 2026 on 14 July 2026. This marks a significant milestone in India’s statistical system as, for the first time, the country has introduced a monthly indicator to measure the performance of the services sector, similar to the Index of Industrial Production (IIP) for industry.
The trial index uses 2024–25 as the base year and initially covers 19 formal services sub-sectors, representing nearly 60% of India’s formal services economy.
What is the Index of Services Production (ISP)?
The Index of Services Production (ISP) is a monthly high-frequency economic indicator designed to measure short-term changes in the output of the formal services sector in India.
Just as the Index of Industrial Production (IIP) tracks the performance of manufacturing, mining, and electricity sectors, the ISP measures the production and performance of key service industries.
The index provides policymakers, economists, businesses, and investors with timely information on the health of India’s largest economic sector.
Need for the Index of Services Production
India has transformed into a services-led economy, with the services sector contributing more than half of the country’s Gross Value Added (GVA) and Gross Domestic Product (GDP).
Despite its dominant role in the economy, India lacked a dedicated monthly indicator to monitor services-sector performance. Policymakers primarily relied on quarterly GDP estimates and indirect indicators, making real-time assessment difficult.
The introduction of ISP fills this important statistical gap by providing:
- Timely measurement of service-sector activity.
- Better monitoring of economic trends.
- Improved policy formulation.
- Enhanced forecasting of GDP growth.
- Better sector-specific analysis.
Coverage of the ISP
The trial Index of Services Production covers 19 formal services sub-sectors, accounting for approximately 60% of India’s organised services economy.
The selected sectors include:
- Wholesale Trade
- Retail Trade
- Accommodation Services
- Food Services
- Air Transport
- Railway Transport
- Road Transport
- Water Transport
- Warehousing
- Real Estate Activities
- Administrative and Support Services
- Professional Services
- Information and Communication Services
- Other formal service activities
The remaining sectors are expected to be incorporated gradually as data quality and availability improve.
Base Year of the Index of Services Production (ISP)
The base year for the Index of Services Production is 2024–25.
A base year serves as the reference period against which future changes in output are measured.
Periodic revision of the base year ensures that statistical indicators reflect the latest structural changes in the economy.
April 2026 Trial Results
The inaugural trial release indicates robust growth across most service industries.
Out of the 19 sub-sectors, 14 recorded double-digit year-on-year growth compared with April 2025.
Top Performing Sectors
| Services Sub-Sector | Growth (April 2026) |
|---|---|
| Accommodation & Food Services | 37.2% |
| Retail Trade | 30.8% |
| Administrative & Support Services | 28.7% |
| Real Estate Activities | 27.7% |
Sectors Showing Decline
| Services Sub-Sector | Growth |
|---|---|
| Air Transport | –13.9% |
| Railway Transport | –0.4% |
The data indicates strong recovery in consumer-oriented and business-support services, while transportation sectors recorded relatively weaker performance during the month.
Difference Between ISP and IIP
| Feature | Index of Services Production (ISP) | Index of Industrial Production (IIP) |
|---|---|---|
| Sector Covered | Services | Industry |
| Introduced By | MoSPI | MoSPI |
| Frequency | Monthly | Monthly |
| Base Year | 2024–25 | 2022–23 (latest revised) |
| Measures | Services output | Industrial output |
| Coverage | Trade, Transport, Hospitality, Real Estate, etc. | Mining, Manufacturing, Electricity |
The two indices together provide a comprehensive picture of short-term economic activity across India’s major sectors.
Methodology and Institutional Framework
The Technical Advisory Committee (TAC) on the Index of Services Production was constituted by MoSPI in May 2025 to develop the methodology and framework for the new index.
The committee recommended:
- Selection of representative service sectors.
- Development of monthly output indicators.
- Standardised statistical methodology.
- Data validation and quality assurance mechanisms.
- Gradual expansion of sectoral coverage.
The trial phase allows refinement of the methodology before the launch of a full-fledged national Services Production Index.
Release Schedule for Index of Services Production (ISP)
MoSPI has announced that the monthly sub-sectoral indices under the ISP framework will be released on the 29th of every month.
These regular releases will provide policymakers and market participants with timely insights into India’s services-sector performance.
Significance of the Index of Services Production
The introduction of ISP has several important implications for India’s economic policymaking and statistical system.
Better Economic Monitoring
The index enables real-time assessment of services-sector performance, reducing dependence on quarterly estimates.
Improved GDP Forecasting
Since services contribute the largest share to India’s economy, the ISP will improve short-term GDP forecasting and national accounts estimation.
Evidence-Based Policymaking
Governments can use monthly data to formulate targeted policies for sectors experiencing slowdown or rapid growth.
Enhanced Investor Confidence
Regular publication of reliable services-sector data improves transparency and supports investment decisions.
Stronger Statistical Framework
The ISP aligns India’s statistical system with international best practices followed by advanced economies that regularly publish service-sector production indices.
Challenges
Despite its significance, several challenges remain.
- Limited coverage during the trial phase.
- Difficulty in measuring service output compared to manufacturing.
- Data collection from diverse service industries.
- Capturing informal sector activities.
- Ensuring timely and accurate reporting.
As data availability improves, future editions are expected to include more service industries.
Way Forward
The trial Index of Services Production represents a major reform in India’s official statistical architecture. Expanding the index to cover a larger share of the services sector, improving data quality, and integrating digital reporting mechanisms will further strengthen its usefulness.
A robust monthly services production index will enable India to better monitor economic activity, improve policy responses, and enhance transparency in economic statistics, thereby supporting the country’s long-term growth strategy.
