• September durable goods orders rose 0.5%, beating the 0.3% forecast but cooling from August's 3.0% surge
  • Core capital goods orders, a key business investment indicator, jumped 0.9% versus the 0.2% expectation
  • Defense aircraft and parts orders surged 30.9%, driving much of the headline growth amid ongoing geopolitical tensions

U.S. durable goods orders demonstrated unexpected resilience in September, climbing 0.5% despite economists' projections for more modest growth. The Commerce Department data released Thursday morning showed manufacturing activity maintaining momentum, though the pace has clearly decelerated from August's robust 3.0% increase.

The underlying details revealed stronger business investment trends than the headline figure suggested. Orders excluding transportation—a closely watched measure that strips out volatile aircraft and vehicle purchases—increased 0.6%, comfortably exceeding the 0.2% consensus estimate. Even more telling was the performance of core capital goods orders, which rose 0.9% against expectations of just 0.2%, signaling that corporate spending on equipment remains healthy despite elevated borrowing costs.

"The core capital goods number is the real story here," said a senior economist at a major investment bank who requested anonymity because they weren't authorized to speak publicly. "Businesses continue to invest in equipment, likely incentivized by tax treatment and the need to enhance productivity in a tight labor market."

Defense sector activity provided a significant boost, with aircraft and parts orders skyrocketing 30.9% as government procurement cycles accelerated amid ongoing international conflicts. The defense surge contributed substantially to the overall transportation category's performance, though non-defense aircraft orders showed more modest growth.

Shipments data, which feeds directly into GDP calculations, also improved. Core capital goods shipments increased 0.9% following a 0.1% decline in August, suggesting business investment could provide a modest lift to third-quarter economic growth figures when they're finalized.

Manufacturing subsectors showed mixed performance. Electrical equipment orders jumped 1.5%, while machinery orders edged up just 0.1%, reflecting the uneven nature of the industrial recovery. The data arrives amid concerns that recent tariff implementations have raised input costs for many manufacturers, with some of the nominal order value increases potentially reflecting higher prices rather than increased volumes.

Efforts to reach several major industrial equipment manufacturers for comment were unsuccessful Thursday morning. A Commerce Department representative declined to provide additional analysis beyond the published data.

The September figures continue a pattern of volatility in durable goods orders, which declined 2.7% in July before August's strong rebound. While the latest data suggests underlying strength in business investment, economists remain cautious about the sustainability of this trend given global economic uncertainty and the potential for interest rates to remain elevated.

Correction: An earlier version of this article misstated the percentage increase in core capital goods shipments. The correct figure is 0.9%, not 0.8%.
