Industrial Production (IIP)

The IIP answers a question investors and policymakers ask every month: are India's factories, mines and power plants actually producing more, or is growth stalling? Published by the National Statistical Office under MoSPI, it is one of the earliest hard signals of how the real economy is doing, well before quarterly GDP arrives.

What it measures

The index tracks the volume of output across three broad sectors: manufacturing, which carries by far the largest weight, plus mining and electricity. It is also presented by use-based categories such as capital goods, consumer durables, consumer non-durables and infrastructure goods, which tell a richer story. Surging capital-goods output, for instance, signals businesses are investing and expanding, while weak consumer-durables points to soft household demand.

A modernised index

In 2026 MoSPI overhauled the series, shifting the base year to 2022-23 from the old 2011-12 and widening the basket to over a thousand products. The revamp, which for the first time formally counts activities like gas, water supply and waste management, was overdue: an index anchored to a decade-old basket increasingly missed how India actually produces today. A fresher base gives a sharper, more credible read on industrial momentum.

How to read the number

IIP is volatile and prone to base effects, so a single month's headline can mislead. A high growth figure may simply reflect a weak comparable month a year earlier rather than genuine acceleration. The smarter approach is to watch the trend over several months and the composition: broad-based growth led by capital and infrastructure goods is healthy, while a number propped up by one volatile segment is fragile.

For markets, a strong IIP supports cyclical and industrial stocks and signals robust demand; persistent weakness, especially in mining or consumer goods, can hint at slowdown and influence how the RBI's MPC weighs growth against inflation. Treat it as a monthly pulse-check, not a verdict.
