Freight Volumes Cool in July: What the TSI Numbers Mean

The Bureau of Transportation Statistics' latest Freight Transportation Services Index (TSI) confirms what many shippers have already sensed on the ground: freight activity is losing momentum. The Freight TSI slipped 0.7% in July 2026 compared with June, erasing the prior month's modest uptick, and now sits 2.0% below its July 2025 level.

It's not a collapse. But it is a signal worth paying attention to, especially since it's happening while other corners of the economy are still holding up reasonably well.

Where the Weakness Came From

Three modes drove the July pullback:

• Air freight

• Pipeline

• Trucking

Rail carloads, rail intermodal, and waterborne volumes all moved in the opposite direction, giving the index some support — but not enough to offset the declines elsewhere.

Passenger transportation told a different story entirely. The Passenger TSI climbed 0.4% in July, its third straight monthly gain, and is running 1.8% ahead of last year. Air travel, intercity rail, and transit all contributed. The index remains below its pre-pandemic high, but the trajectory has clearly turned upward.

Freight Is the Outlier, Not the Economy

Set alongside other monthly indicators, freight looks increasingly like the exception rather than the rule. Industrial production ticked up, the ISM index pointed to expanding manufacturing activity, and personal income kept growing. Housing starts cooled after a strong June, but nothing in the broader data suggests a sharp downturn is underway.

Freight is softening anyway — and that divergence is exactly what makes this month's

numbers worth watching closely.

What It Means for GAIN Clients

• Capacity: Softer trucking volumes may push some carriers toward more flexible rates and service commitments in the near term.

• Mode mix: Continued strength in rail intermodal and water transport gives shippers who can flex between modes more room to find value.

• Visibility and planning: Swings like July's underscore why waiting on a monthly index to confirm a trend is often too slow. Real-time demand signals and exception-based monitoring matter more than ever.

We're already seeing clients revisit carrier mix and inventory positioning in response. The organizations that treat the TSI as one data point among many — rather than a lagging headline — tend to adapt faster and with less disruption to their customer commitments.

What to Watch Next

The August TSI is due out on October 14. Until then, the open question is simple: was July's dip a one-month pause, or the start of a longer soft patch in freight demand?
