The U.S. trucking market, often considered a barometer of economic activity, presented a puzzling picture in September with conflicting indicators that have left analysts searching for clarity. While spot rates showed modest increases—typically signaling market recovery—a deeper examination revealed declining freight volumes, casting uncertainty over the traditionally busy fourth quarter.
Key Metrics Reveal Divergent Trends
DAT Freight and Analytics' Truckload Volume Index (TVI), a standardized benchmark using January 2015 as its 100-point baseline, documented these contradictory movements across different equipment types:
- Dry Van: TVI fell to 234, marking 3% monthly and 2% annual declines—concerning signs for this dominant freight category.
- Reefer: The 184 TVI reflected a sharp 7% monthly drop despite 2% annual growth, suggesting potential seasonal or sector-specific weakness.
- Flatbed: At 307 TVI, this segment showed modest 1% monthly and stronger 9% annual growth, possibly tied to infrastructure or manufacturing activity.
Spot rates told a different story, with all equipment types showing small increases—dry van ($2.05/mile, +$0.02), reefer ($2.44/mile, +$0.03), and flatbed ($2.50/mile, +$0.01). Contract rates painted yet another picture, with most categories showing flat-to-declining trends year-over-year.
Behind the Contradictions: Capacity Dynamics
DAT Chief Analyst Ken Adamo explained these anomalies through structural factors rather than demand growth:
"The rate increases we're seeing stem from freight imbalances and capacity fluctuations, not volume expansion," Adamo noted. "This creates a problematic scenario where brokers face compressed margins without volume offsets, while some carriers benefit temporarily from specific lane improvements."
The analysis highlights how backhaul lanes—particularly long-distance return routes to major shipping hubs—experience disproportionate rate percentage increases due to their lower baseline rates. However, these gains often mask systemic weakness rather than indicate broad market health.
Peak Season Outlook: Tempered Expectations
With September port volumes weakening after a strong August and carrier authorizations declining by approximately 1,200—matching typical January attrition levels—Adamo offered a cautious peak season forecast:
"We anticipate continued softness, with some small carriers potentially benefiting from select lane improvements. However, the broader market appears headed toward further carrier exits until reaching macroeconomic equilibrium."
This outlook suggests that while certain operators may find opportunities, the industry overall faces challenging months ahead without clear demand catalysts.
Strategic Implications
Market participants must navigate this environment carefully:
- Brokers: Must monitor margin pressures amid stagnant volumes
- Carriers: Should optimize networks to capitalize on imbalanced lanes while preparing for potential downturns
- Shippers: May encounter spot/contract rate divergences requiring flexible procurement strategies
The September data underscores how traditional indicators can provide conflicting messages during transitional periods. Stakeholders would benefit from analyzing micro-level lane dynamics rather than relying solely on aggregate metrics when making operational and financial decisions.
