Economic activity in the US manufacturing sector fell back into contraction in March after a brief expansion as businesses braced for US president Donald Trump's threatened tariffs on imports.
The manufacturing purchasing managers' index fell to 49 in March, down from the 50.3 in February, the Institute for Supply Management reported Tuesday. That followed three months of expansion — above the breakeven threshold of 50 — following 26 months of contraction.
The new orders index contracted for a second month in a row, falling to 45.2, down by 3.4 points from the prior month. Production fell to 48.3 from 50.7. New export orders fell to 49.6 in March from 51.4 the prior month.
"Demand and production retreated and destaffing continued, as panelists' companies responded to demand confusion," ISM said. "Prices growth accelerated due to tariffs, causing new order placement backlogs, supplier delivery slowdowns and manufacturing inventory growth."
The prices index surged to 69.4, up from 62.4 in February and the highest since mid-2022. Employment fell by 2.9 points to 47.6.
The supplier delivery index fell by 1 point to 53.5, indicating ongoing slowing in deliveries and slowing demand.
Trump plans to unveil sweeping "reciprocal" tariffs on major foreign trade partners on 2 April after previewing or announcing multiple tariff actions since taking office, including a 20pc tariff on all imports from China and a 25pc tax on all imported steel and aluminum that both took effect last month. Trump last month also announced a 25pc tariff on all imported cars, trucks and auto parts, scheduled to go into effect on 3 April. The measures, together with mass federal government layoffs and spending cuts, spooked US equity markets, which last month posted heavy losses.
Comments focus on tariff confusion
Comments from survey participants highlighted uncertainty over how Trump's tariff plans would effect operations and the economy.
"Acute shortages continue to impact supply chain continuity," a transportation equipment executive said. "Chinese restrictions on critical minerals such as germanium have caused major shortages, resulting in all supply needed in 2025 already assumed — and, not surprisingly, significant price increases as a result."
"Customers are pulling in orders due to anxiety about continued tariffs and pricing pressures," according to a computer and electronic products executive.
"Business condition is deteriorating at a fast pace," a machinery executive commented. "Tariffs and economic uncertainty are making the current business environment challenging."
"New order levels have increased and are better than expected," a fabricated metals executive said. "We suspect that our customers are trying to build inventory at current prices to get ahead of expected tariff and related cost increases."
