The Old Economic Compass
For years, the Index of Industrial Production (IIP) has been a cornerstone of Indian economic analysis. Released monthly by the National Statistical Office (NSO), it offers a high-frequency snapshot of how the industrial sector is performing. It measures
the change in the volume of production for a basket of industrial goods, covering major sectors like manufacturing, mining, and electricity. Policymakers at the Reserve Bank of India, government officials, and market analysts have all used the IIP as a vital sign to gauge industrial momentum, track business cycles, and make crucial policy decisions. Since its inception, it has provided an essential, if not always perfect, reading of the country's industrial health, giving an early indication of economic trends long before quarterly GDP figures are released.
A Growing Blind Spot
The Indian economy, however, has fundamentally changed. The services sector—encompassing everything from IT and finance to transport and hospitality—is now the dominant driver of the economy. It contributes well over 50% to India's Gross Value Added (GVA), dwarfing the industrial sector's contribution. This creates a significant data gap. The IIP, with its heavy focus on manufacturing (which has a weight of over 77% in the index), provides little to no information about this vast and dynamic part of the economy. Relying primarily on an industrial index to understand a services-dominated economy is like trying to drive a car by only looking in the rearview mirror. It captures where we have been, but it misses the majority of the road ahead. This limitation can lead to a skewed understanding of overall economic health, as the IIP can be volatile and may not reflect the momentum in the broader economy.
The Case for a Services Index
Recognising this gap, there has been a growing call for a services equivalent to the IIP. In fact, the Ministry of Statistics and Programme Implementation (MoSPI) recently announced plans to launch an Index of Services Production (ISP). While private surveys like the S&P Global Services PMI already provide a monthly pulse of the services sector, an official government-backed index would carry more weight and provide a more comprehensive picture. The proposed ISP aims to measure changes in the real output of key service industries, providing a high-frequency indicator that complements the IIP. It would offer a balanced and more complete dashboard for assessing short-term economic activity, combining data from sources like GST collections and other administrative data to build a reliable monthly reading.
Better Data, Wiser Decisions
The benefits of such an index are manifold. For the Reserve Bank of India, it would provide a much clearer signal for making monetary policy decisions, offering insights into demand conditions and inflationary pressures across the entire economy, not just the industrial part. The finance ministry and other government bodies could use this timely data for better fiscal planning and designing more targeted policies to support growth. For businesses and investors, a reliable ISP would reduce uncertainty and improve forecasting, allowing for better strategic decisions. By combining the insights from both the IIP and a new ISP, policymakers and analysts would finally have a holistic, high-frequency view of India’s economic engine, capturing the performance of both goods and services in near real-time.
