US Service Sector Growth Slows in March Amid Economic Resilience

Non-manufacturing data showed a slight slowdown in March, but overall growth momentum remains. Most industries are expanding, and key indicators, although declining, remain in expansion territory. Labor shortages and trade conditions are key areas of concern. Experts believe the economy is moving towards a more sustainable growth path, and the future outlook remains optimistic.
US Service Sector Growth Slows in March Amid Economic Resilience

Introduction: Navigating Economic Waters

In the vast ocean of economic activity, various indicators serve as navigational buoys, helping observers chart the course of growth. The March non-manufacturing data, released by the Institute for Supply Management (ISM), represents one such important marker. While showing some moderation from February's strong performance, the report reveals an economy demonstrating remarkable resilience and continued expansion.

Overall Performance: Moderate Growth Amidst Expansion

The Non-Manufacturing Index (NMI) declined by 3.6 percentage points to 56.1 in March, following February's robust reading. While this moderation has sparked some concerns, several contextual factors merit consideration:

The Significance of NMI

The NMI serves as a crucial barometer of U.S. non-manufacturing activity, derived from monthly surveys of purchasing and supply executives. Readings above 50 indicate expansion, while those below 50 signal contraction. The index provides early insights into the health of the services sector, which constitutes approximately 80% of the U.S. economy.

Long-Term Expansion Continues

March marked the 110th consecutive month of NMI growth, an unprecedented streak highlighting the sector's durability. While the current reading sits 2.4 percentage points below the 12-month average of 58.5, it remains solidly in expansion territory.

Quarterly Perspective

The first quarter average NMI of 57.5 suggests healthy momentum entering the second quarter, with March's moderation representing normal economic fluctuation rather than deterioration.

Sector Performance: Broad-Based Growth

The ISM report revealed expansion in 16 of 18 tracked non-manufacturing industries, demonstrating diversified strength across the economy:

Expanding Industries

  • Construction: Benefiting from housing market recovery and infrastructure investment
  • Professional Services: Driven by technological innovation and corporate demand
  • Healthcare: Supported by demographic trends and medical needs
  • Accommodation/Food Services: Fueled by tourism and consumer spending
  • Information Technology: Growing with digital transformation

Contracting Sectors

Only education services and retail trade showed contraction, reflecting industry-specific challenges rather than broad economic weakness.

Key Indicators: Mixed Signals Within Expansion

Component indices presented a nuanced picture:

Business Activity

The business activity index declined 7.3 points to 57.4, marking 116 consecutive months of growth but at a slower pace.

New Orders

New orders fell 6.2 points to 59.0, maintaining strong demand signals despite the moderation.

Employment

The employment index rose slightly to 55.9, continuing its 61-month expansion streak amid tight labor markets.

Supplier Deliveries

The supplier deliveries index slowed to 52.0, suggesting persistent supply chain challenges.

Prices

Prices rose 4.3 points to 58.7, reflecting ongoing but manageable inflationary pressures.

Business Sentiment: Cautious Optimism

Survey respondents highlighted two primary concerns:

  • Labor shortages across multiple industries
  • Ongoing trade policy uncertainties

However, many expressed relief about temporary tariff suspensions and optimism about future quarters.

Expert Analysis: Sustainable Growth Path

Tony Nieves, Chair of the ISM Non-Manufacturing Business Survey Committee, offered measured perspective:

  • Current readings represent healthy, sustainable expansion
  • Price increases reflect specific commodity movements rather than systemic inflation
  • Trade tensions show signs of easing
  • Labor market dynamics reflect structural changes requiring adaptation

Conclusion: Resilient Fundamentals

The March NMI report paints a picture of an economy transitioning from rapid to more sustainable growth. With most sectors expanding, employment growing, and demand remaining robust, the non-manufacturing sector continues to anchor overall economic performance. While challenges exist in labor markets and trade policy, the underlying fundamentals appear sound as the economy enters the second quarter.
