Composite PMI (India)
India's Composite PMI is a blended activity index combining the Manufacturing PMI and the Services PMI compiled by S&P Global, producing a single monthly reading that captures the overall pace of private sector economic activity.
The S&P Global India Composite PMI Output Index is constructed by weighting the manufacturing output sub-index and the services business activity sub-index according to their respective contributions to GDP. Given that services account for a significantly larger share of India's economy than manufacturing, the services component carries greater weight, meaning a strong services print can keep the composite index elevated even when manufacturing activity softens.
A Composite PMI above 50 signals that the majority of surveyed companies across both sectors reported improvement relative to the prior month. Historical analysis shows that sustained Composite PMI readings above 55 are associated with GDP growth rates above 6.5 per cent on a year-on-year basis, though this relationship is not mechanical and can break down during supply chain disruptions, financial stress events, or data quality issues.
The index is released roughly five to ten calendar days after month-end, making it one of the first hard data points policymakers and investors receive for any given month. Bond markets watch the index closely: an unexpected jump can trigger pricing-out of rate cuts, steepening the yield curve, while a surprise contraction print can rally government securities as rate-cut expectations firm up.
For equity investors, the Composite PMI is particularly useful in cyclical sector rotation decisions. Industrial, consumer discretionary, and financial stocks have historically outperformed in environments where the Composite PMI is rising and above 52, while defensive sectors such as FMCG, healthcare, and utilities have tended to attract capital when the index dips below the 50 threshold.
It is worth noting that PMI surveys capture sentiment and activity changes at the firm level but do not measure the absolute size of the economy. A Composite PMI of 50 does not mean zero GDP growth — it means no net change from the prior month. Additionally, informal sector activity — which remains substantial in India — is not captured in the PMI survey sample, so the index can diverge from official GDP prints during periods of significant informal sector stress or recovery.
