- U.S. Manufacturing PMI®

Manufacturing Sector Contracted in March After Two Consecutive Months of Expansion
The Manufacturing PMI® registered at 49.0% in March, 1.3 percentage point lower compared to the 50.3 percent reported in February according to the Institute for Supply Management® (ISM®). According to Timothy Fiore, Chair of the Institute for Supply Management Manufacturing®, in March, the Manufacturing PMI® reversed its recent momentum to register below its reading in December. Of the five sub indexes that directly factor into the Manufacturing PMI®, two (Supplier Deliveries and Inventories) were in expansion territory, the same number as in February, when Production and Supplier Deliveries indicated growth. Slower supplier deliveries and expanded inventories in March are not considered positives for the economy: Both conditions figure to be temporary and are driven by tariff concerns, either delaying buyer/seller negotiations or advancing material deliveries that will be reversed after tariffs are deployed, leading to a drawdown of manufacturing inventory.
ISM® states a reading above 50% shows that the manufacturing economy is generally expanding; below 50% indicates that it is generally contracting. The index is based on a monthly survey of supply chain managers and measures general direction of economic trends in manufacturing and other sectors.
