What is the Proposed Services Index?
The services sector is the dominant force in the Indian economy, contributing over half of the country's Gross Value Added (GVA). Yet, policymakers have historically lacked a high-frequency, official measure of its performance, analogous to the Index
of Industrial Production (IIP) for manufacturing. To address this, the National Statistical Office (NSO) has proposed the Index of Services Production (ISP). This monthly index aims to measure the real output of the formal services sector, providing a timely snapshot of activity in areas like trade, transport, IT, finance, and hospitality. The framework, developed by a technical committee, proposes using 2024-25 as the base year and will primarily draw on aggregated data from the Goods and Services Tax (GST) network, supplemented by administrative data from various ministries for sectors like railways and aviation. The first trial release is scheduled for mid-July 2026.
The Key Benefit: Sharper Economic Vision
The primary advantage of the ISP is providing policymakers, the Reserve Bank of India, and businesses with a much clearer, near-real-time view of the economy's health. Currently, a comprehensive picture of the services sector only emerges with quarterly GDP estimates, which have a significant lag. A monthly index would allow for earlier identification of trends, enabling faster and more targeted policy responses. For example, it could help in better forecasting economic growth, analysing business cycles, and designing interventions to support specific service industries. By complementing the IIP, the ISP will offer a more holistic monthly gauge of economic momentum, moving beyond anecdotal evidence or private surveys to a robust, official statistic.
The Inherent Risk: The Challenge of Measurement
The biggest risk lies in the immense difficulty of accurately measuring a sector as diverse and fragmented as services. Unlike manufacturing, where counting physical units is straightforward, service output is often intangible and harder to quantify. The sector ranges from multinational IT firms and large banks to millions of small traders, transporters, and consultants. The ISP's reliance on GST data means it will primarily capture the formal sector, potentially leaving out a significant portion of the informal economy. Furthermore, some crucial services like health and education are largely exempt from GST, requiring different data sources like the new Annual Survey of Incorporated Service Sector Enterprises (ASISSE), which will take time to become fully established. Ensuring data quality, creating appropriate price deflators to measure real growth, and keeping the index representative of this dynamic sector are all significant hurdles.
Practical Next Steps: The Path Forward
The Ministry of Statistics and Programme Implementation (MoSPI) has outlined a cautious, phased approach. The initial release of the ISP in July 2026 will be on a trial basis. This trial period is crucial for gathering feedback from stakeholders, validating the methodology, and ensuring the stability of the data sources before the index is officially launched for regular publication. The plan is to release the index with a lag of about 60 days. A key step involves refining the use of GST data as a proxy for turnover and developing accurate price indices to convert these nominal values into a real volume index. Concurrently, efforts to integrate data from other sources like the ASISSE for GST-exempt sectors will continue, with the aim of gradually expanding the index's coverage and accuracy over time.
