India's manufacturing sector activities moderated in January as new orders and production expanded at a slower rate as the new wave of COVID-19 restricted growth and affected business confidence that slipped to a 19-month low, a monthly survey said on Tuesday. The seasonally adjusted IHS Markit India Manufacturing Purchasing Managers’ Index (PMI) was at 54.0 in January, down from 55.5 in December and signalled the weakest improvement in the health of the sector since last September.
