US Mar ISM Manufacturing PMI: Tariff Uncertainty Continues to Weigh on Demand as Price Pressures Reignite

2025-04-02

The U.S. manufacturing PMI declined to 49.0 in March (prior: 50.3), marking its first contractionary reading this year, according to Institute for Supply Management (ISM) on April 1.

Breaking down the components, the new orders index contracted further to 45.2 (prior: 48.6), its lowest level since May 2023, dragging the new orders minus customer inventories metric into negative territory at -1.6 (prior: 3.3). Production also shifted from expansion to contraction at 48.3 (prior: 50.7), while the employment index fell to 44.7 (prior: 47.6).

The report noted that heightened uncertainty around tariff policy continued to dampen demand and reduce corporate investment appetite. Moreover, ongoing discussion between manufacturers and customers over how to absorb tariff-related costs, all these factors has further weakened new orders, production, and hiring activity.

Only the inventories index and supplier delivery times remained in expansionary territory, reaching 53.4 (prior: 49.9) and 53.5 (prior: 54.5) respectively. Meanwhile, the imports index remained in expansion at 50.1 (prior: 52.6), indicating that manufacturers continue to front-load orders in anticipation of potential tariff impacts—leading to inventory buildup and longer lead times.

Elsewhere, the prices index surged again to 69.4 (prior: 62.4), its sixth consecutive monthly increase and the highest level since June 2022. The proportion of firms reporting higher prices rose to 46.0% (prior: 31.4%), compared to just 12.2% in November. All 15 surveyed industries reported rising input costs, with some noting that upward pressure on prices had already led to a drop in orders.

Overall, rising tariff uncertainty and escalating price pressures have significantly eroded both business and consumer confidence. At the same time, unresolved questions over how tariffs will be absorbed between producers and buyers have further suppressed demand for new orders, production, and hiring, while precautionary inventory accumulation continues to elevate stock levels.

Following the data release, the Atlanta Fed’s GDPNow model revised its estimate for Q1 annualized GDP growth downward from -2.8% to -3.7%, heightening market concerns about a potential recession. As a result, expectations for rate cuts intensified, and the U.S. 10-year Treasury yield fell further to around 4.16%.
