The Ministry of Statistics and Programme Implementation released an approach paper to introduce the Index of Service Production (ISP) to track services output monthly.
ISP will measure the performance of the services sector every month, similar to the Index of Industrial Production for industry.
It uses 2024–25 as the base year and mainly relies on GST data along with official government data sources.
It is needed because services form more than half of India’s GDP, but there is no proper monthly output-based indicator at present.
Currently, policymakers depend on the Purchasing Managers' Index, which is survey-based and does not measure actual output.
