U.S. ISM Non-Manufacturing PMI Shows Modest Expansion in April

Overview of the Latest Release
On May 5, 2025, the Institute for Supply Management (ISM) released its Non-Manufacturing Purchasing Managers’ Index (PMI) for April 2025, reporting a value of 51.6, surpassing market expectations of 50.2 and a slight improvement from the previous month’s reading of 50.8. This uptick indicates moderate expansion in the U.S. non-manufacturing sector.

The ISM Non-Manufacturing PMI is a composite index derived from several key components, including Business Activity, New Orders, Employment, and Supplier Deliveries. A reading above 50 signifies growth, while a figure below 50 points to contraction. The latest figure suggests that while the sector is expanding, the pace remains modest, reflecting stable but cautious economic conditions.

What is the ISM Non-Manufacturing PMI Report?
The ISM Non-Manufacturing PMI report, also known as the ISM Services PMI, provides a snapshot of the economic conditions in the U.S. non-manufacturing sector. This sector includes industries such as finance, insurance, real estate, health services, and other service-based businesses, which together form a significant portion of the U.S. economy. The PMI is calculated based on monthly survey responses from purchasing and supply executives across over 60 sectors, reflecting their perceptions of business activity, new orders, employment, and supplier deliveries.

A PMI value above 50 indicates growth, while a reading below 50 suggests contraction in the sector. The report is widely regarded as a leading indicator of economic health, providing insight into both short-term trends and longer-term economic conditions.

Detailed PMI Breakdown
The Business Activity subcomponent showed signs of expansion, albeit at a slower pace than previous months. The New Orders index indicates that demand for services is still holding steady, providing support to overall sector growth. The Employment index has been a critical driver for the index, though fluctuations suggest some caution in hiring trends. Supplier performance improved slightly, suggesting that supply chain conditions may be stabilizing after previous disruptions.

Market Implications and USD Outlook
With the PMI surpassing expectations, this data is generally interpreted as a positive indicator for the U.S. economy. A stronger-than-expected PMI could bolster confidence in the service sector, which represents the largest portion of the U.S. economy. Investors may interpret the result as a signal of resilience, possibly contributing to short-term strength for the U.S. Dollar (USD).

While the PMI shows growth, its modest pace suggests that there are still headwinds facing the non-manufacturing sector. Factors such as inflation concerns, geopolitical risks, and ongoing supply chain constraints are likely still influencing business sentiment.

Historical Context and Trend Analysis
Looking at the historical data, the current PMI value of 51.6 is relatively in line with the broader trend of moderate expansion that has characterized the U.S. service sector over the past few years. The chart below shows the recent movements of the ISM Non-Manufacturing PMI, illustrating a general pattern of stability, with occasional spikes that signal stronger periods of growth.

In the broader context of the economic recovery post-pandemic, the April PMI reading offers further evidence that the U.S. economy is navigating through uncertainties with modest but consistent expansion.
