The U.S. services sector—responsible for more than 80% of the nation’s economic output—registered its slowest growth rate in nine months in March 2025, according to the latest data released by the Institute for Supply Management (ISM). The ISM’s Services PMI® dropped to 50.8, down sharply from 53.5 in February, and just barely above the threshold that separates expansion from contraction.
While the index remains in growth territory, the decline points to rising caution among service providers, with companies signaling concerns over elevated input costs, tariff-driven uncertainty, and weaker government spending.
Tariff Uncertainty Sends Ripples Through the Economy
Much of the sector’s hesitation has been attributed to newly announced U.S. import tariffs, including a 10% universal tariff and additional surcharges targeting countries like China, Vietnam, and the EU. These measures, widely referred to as the “Liberation Day” tariffs by the administration, have already begun to disrupt supply expectations and complicate procurement strategies.
“The uncertainty surrounding tariff implementation and the broader global trade outlook is forcing service-sector leaders to tighten budgets and pause expansion plans,” said Nora Edmonds, senior economist at ClearBridge Analytics. “The ripple effects go well beyond goods—it’s hitting logistics firms, consultants, hospitality, IT services, and others.”
Employment and New Orders Show Signs of Strain
The Employment Index slipped to 46.2%, marking its first contraction in six months and suggesting that employers are either scaling back hiring or taking a wait-and-see approach to workforce expansion.
Meanwhile, new orders—typically a forward-looking indicator of business confidence—also slowed, with companies citing fewer client projects, delayed decision-making, and prolonged procurement cycles as key factors.
ISM’s survey respondents described the month as “steady, but fragile,” with several noting that while backlogs remain manageable, they are becoming more difficult to replenish with new business.
Prices Still Rising
Despite slowing growth, cost pressures remain stubborn. The Prices Index clocked in at 60.9%, indicating continued inflation across core inputs such as labor, transportation, and materials. Service firms in industries like construction, logistics, and retail distribution reported rising rates from subcontractors and vendors—many of whom are also adjusting pricing to account for tariff-related increases.
“The margin squeeze is real,” said one survey respondent from the transportation sector. “Fuel and labor costs are up, and now we’re dealing with a tariff cascade. It’s a triple whammy.”
A Mild Start to 2025
The March numbers underscore growing concern about the broader direction of the U.S. economy in 2025. Economists are now revising GDP forecasts, with some suggesting the first quarter could show annualized growth of less than 0.5%, down from earlier projections closer to 1.2%.
Still, not all indicators are negative. Some sectors—including healthcare and select tech services—continue to post solid performance. But the general tone across ISM’s respondent pool points to increasing caution, selective spending, and a prioritization of core services over expansion.
What to Watch Next
Looking ahead, all eyes will be on how businesses adjust to ongoing trade policies and whether federal economic support—through spending or rate adjustments—can help reignite momentum.
The logistics industry, in particular, will play a critical role in navigating the turbulence, as supply chain fluidity and cost efficiency become paramount in maintaining service delivery at scale.
