Introduction
The Ministry of Statistics and Programme Implementation (MOSPI), Government of India, announced the operational deployment of the Index of Services Production (ISP). Positioned as a direct macroeconomic counterpart to the legacy Index of Industrial Production (IIP), the first-ever monthly ISP—compiled with the baseline year of 2024-25—will be officially released on July 14, 2026, measuring data from April 2026. Subsequent data sets will be published on the 29th day of every month with a standardized 60-day operational lag.
This structural development represents an essential evolution in India’s statistical governance and macroeconomic policy formulation. For decades, India’s fast-growing economic growth model has been unique due to its service-led nature, with the tertiary sector contributing over 54% to the Gross Value Added (GVA). Despite this dominance, economic planners lacked a high-frequency, monthly quantitative tool to measure short-term changes in the services industry, forcing an over-reliance on proxy indicators like purchasing managers’ indices (PMI) or credit growth data.

For civil services and staff selection candidates, analyzing the ISP is vital. It directly impacts how the Reserve Bank of India (RBI) conducts monetary policy, how the state handles formal-informal economic divides, and how structural challenges in economic development are diagnosed. This article explores the methodological, fiscal, and operational aspects of this new economic tool.
Background and Context
The conceptual framework for India’s first service index was finalized following detailed consultations with a specialized Technical Advisory Committee (TAC). This high-level panel was constituted in May 2025 and led by Debjani Ghosh of the national think tank, NITI Aayog.
Five Important Key Points
- The Ministry of Statistics will launch the first Index of Services Production (ISP) on July 14, 2026, using 2024-25 as its base year.
- The ISP functions as the macroeconomic counterpart to the Index of Industrial Production (IIP), specifically tracking short-term changes in the services sector.
- The conceptual design and sub-sectoral weight distribution were finalized by a NITI Aayog-headed Technical Advisory Committee formed in May 2025.
- All future index numbers will be tracked and published monthly with a fixed 60-day reporting lag.
- Economists argue that the tool will help address structural challenges by providing accurate data regarding uneven consumption and the organized-informal economic divide.
Methodological and Structural Design
The Index of Services Production is designed to provide a real-time, volume-based quantitative estimate of the output of selected service industries over a specific timeframe. Unlike the quarterly or annual Gross Domestic Product (GDP) estimates which measure monetary value, the ISP isolates price inflation to measure pure physical and operational throughput. The index covers critical sub-sectors including transport and logistics, storage, communication, trade, hospitality, financial services, real estate, and professional business services.
By fixing 2024-25 as the base year, the index captures the post-pandemic shifts in corporate and consumer behaviors. The index utilizes a modified Laspeyres price-index formula, which weights sub-sectors according to their relative share in the baseline national accounts. Data streams are collated from multiple administrative line ministries, including the Department of Telecommunications, the Ministry of Civil Aviation, the RBI, and the Insurance Regulatory and Development Authority (IRDAI).
Correcting the Structural Imbalances in Indian Macroeconomics
The introduction of the ISP comes at a time when prominent economists have highlighted structural challenges in India’s growth path. Studies indicate that post-pandemic consumption patterns have been highly uneven, driven primarily by formal urban hiring and easy access to retail credit. Without precise sub-sectoral tracking, broad economic policies risked overlooking deep distress within informal services and lower-income household segments.
The ISP will serve as an early warning system for policy planners. For example, a sudden drop in the transport and trade sub-index would signify a slowdown in rural demand long before it surfaces in annual GDP data. By mapping the performance of contact-intensive sectors like retail trade and hospitality against digitized services like financial technology, the index enables targeted fiscal interventions to bridge the organized-informal divide.
Strategic Implications for Monetary and Fiscal Policy
For the Reserve Bank of India’s Monetary Policy Committee (MPC), the ISP provides a high-frequency indicator to calibrate the repo rate and manage banking liquidity. Previously, the MPC had to evaluate service inflation and service demand through qualitative sentiment surveys. The monthly availability of hard, volume-based service sector output data reduces tracking lags, enabling data-driven monetary choices.
On the fiscal front, the index allows the Ministry of Finance to monitor the revenue efficiency of the Goods and Services Tax (GST). By comparing the physical volume of services indexed under ISP with the nominal GST collection data from the same sub-sectors, tax authorities can identify tax evasion, map input tax credit anomalies, and optimize sector-specific tax structures.
The Bihar Connection: Tracking the Growth of a Consumer Economy
The deployment of the ISP carries significant relevance for the macroeconomic planning of Bihar. Unlike industrialized states, Bihar has transitioned directly from an agrarian economy to a service-heavy state, with the tertiary sector driving nearly 60% of its State Gross Domestic Product (SGSDP). This growth is driven by the rapid expansion of communication networks, retail trade, and construction-linked services. However, a significant portion of Bihar’s service economy operates within unorganized and unmonitored settings.
The standardized tracking of service metrics under the national ISP framework will allow Bihar’s planning department to measure the state’s internal consumption velocity. Because a substantial chunk of Bihar’s domestic income is derived from remittances sent home by migrant workers employed in the construction and logistics services of other states, a nationwide service index will give Bihar an empirical baseline to forecast remittance inflows and design targeted social safety nets for rural families left behind.
Challenges in Data Collection and Compilation
The primary operational challenge confronting MOSPI is the inherent complexity of gathering high-frequency data from a fragmented and largely informal service sector. While tracking industrial output in the IIP is simplified by standardized manufacturing units and factory returns, measuring service output is abstract.
Sub-sectors like professional consultancies, software development, and retail trade are highly decentralized. Securing timely monthly data submissions from private entities across 28 states requires robust digital compliance systems. If reporting agencies experience persistent delays, the index will suffer from high revision rates, undermining its reliability as a real-time policy guide.
Way Forward
- Comprehensive Digital Integration: MOSPI must integrate the ISP reporting architecture directly with the GST Network (GSTN) portal to auto-populate service volume trends via e-way bills and electronic invoicing.
- Expanding Informal Sector Sampling: A specialized sub-sample survey tracking unorganized service hubs must be integrated into subsequent revisions to balance the formal corporate bias of baseline metrics.
- Federal Statistical Capacity Building: The central government should provide technical assistance to State Directorates of Economics and Statistics to compile corresponding State Indices of Services Production (SISP) for localized planning.
- Harmonisation with International Standards: The ISP framework must be continually aligned with the United Nations International Standard Industrial Classification (ISIC) to ensure global compatibility for trade negotiations.
