What is the Proposed Services Index?
The Ministry of Statistics and Programme Implementation (MoSPI) is launching the Index of Services Production (ISP), a new high-frequency economic indicator. Think of it as a sibling to the long-standing Index of Industrial Production (IIP), which tracks
the manufacturing sector. The ISP is designed to give a monthly snapshot of the real output of India's formal services economy. The first trial release, with a base year of 2024-25, is scheduled for July 14, 2026, marking a significant step in measuring the country's largest economic sector.
The Economic Blind Spot It Aims to Fix
For decades, policymakers have been navigating with a partial view of the economy. The services sector contributes more than half of India's Gross Value Added (GVA), but there has been no official, monthly government data to track its performance. Currently, officials rely on proxies like the privately compiled Purchasing Managers' Index (PMI), which measures sentiment rather than actual output, alongside other indirect data points. Economists have long argued this absence is a major handicap, limiting the ability of the RBI and Finance Ministry to make timely and accurate decisions on everything from interest rates to fiscal support.
The 'Utility': A New Toolkit for Policymakers
The primary utility of the ISP is to replace guesswork with granular data. By providing a reliable, high-frequency measure of services activity, the index will empower policymakers with a clearer, more balanced view of economic momentum. It will help in better economic forecasting, business cycle analysis, and crafting more effective, evidence-based policies. For businesses and investors, the ISP will offer a timely indicator of activity in India's biggest growth driver, complementing the IIP to provide a complete picture of the economy's health.
The 'Risk': The Challenge of Measurement
Measuring the services sector is notoriously difficult due to its sheer diversity and intangible nature. Unlike a factory producing a set number of cars, services range from IT and banking to retail trade, transport, and real estate. A huge portion of this sector is also informal, making data collection incredibly complex. The initial ISP will focus on the formal sector, leveraging administrative records and, crucially, GST data, which provides monthly information from millions of businesses. However, this means key areas like the vast informal services economy, as well as non-market services, are currently excluded.
How It Will Work and What It Covers
The ISP will be compiled using a mix of sources. Aggregated data from GST returns will be a cornerstone, providing a wealth of information on business turnover. This will be combined with administrative data from specific sectors like railways, aviation, banking, and insurance. The index will have weights assigned to various sub-sectors, with information and computer services having the largest share at nearly 22%, followed by retail trade (18.5%) and administrative support services (14.4%). Some crucial areas like health and education will be excluded for now but are expected to be added later as more data becomes available from a new annual survey.
The Road Ahead
The rollout will be phased. Following the first trial release on July 14, MoSPI will continue to publish trial indices monthly with a lag of about 60 days. This initial period is designed to gather feedback from stakeholders and validate the methodology before the index is finalised for regular publication. This cautious approach highlights the statistical complexities involved. The success of the ISP will depend not just on its technical robustness but also on its ability to evolve and gradually expand its coverage to paint an even more accurate portrait of India's dynamic services economy.
