Truckload Volumes Decline While Spot Rates Rise in May

DAT's May market report reveals a counterintuitive trend: even as truckload spot rates continue their upward trajectory, actual freight volumes are declining. This divergence signals a market experiencing **capacity constraints** despite reduced shipper demand, suggesting carriers are becoming more selective about loads and shippers are pulling back on freight commitments. For supply chain professionals, this creates a complex pricing environment where transportation costs remain elevated even as overall freight movement slackens—a dynamic that typically precedes either demand recovery or significant market correction.

The simultaneous decline in volumes and rise in rates reflects carrier discipline and consolidation in the trucking sector. Rather than compete on volume, carriers are maintaining pricing power by refusing unprofitable loads, a strategy that protects margins but signals underlying freight market weakness. This puts shippers in a bind: they cannot leverage declining volumes to negotiate better rates because available capacity remains tight relative to their urgent shipments.

The implications for supply chain strategy are substantial. Organizations relying on spot market freight should prepare for persistent rate pressure and consider locking in contracted capacity while it remains available. Forward-looking teams should also monitor whether this May softness in volumes represents a temporary seasonal adjustment or an early warning signal of demand contraction heading into the summer months.
