Q1 Freight Costs Soar as Diesel Hits $5, Capacity Tightens

Key Details Shipper spending jumped 12.9% in Q1 2026 compared to the previous quarter, with annual increases reaching 21.8% - the largest spike since the pandemic freight boom. However, shipment volumes remained flat, dipping just 0.3% quarter over quarter, signaling a market driven by supply constraints rather than demand growth. Why It Matters Diesel prices spiked dramatically in March, including a record weekly jump of nearly $1 per gallon. The national average retail diesel price has now climbed above $5, directly translating into higher fuel surcharges for shippers already dealing with tightening capacity and rising contract rates. Capacity Squeeze Intensifies Fewer trucks competing for freight - not increased shipping volumes - is driving higher rates. Smaller fleets and owner-operators are exiting the market due to rising fuel and operating costs, reinforcing the capacity shortage. The U.S. Bank Freight Payment Index shows carrier pricing power climbed to 216.7 while the shipments index remained weak at 75.9. Regional Impact The Midwest led in both volume and spending growth, while the Southwest and Southeast experienced shipment declines but still posted double-digit spending increases. This widespread pattern underscores how severe the capacity tightness has become across all regions. Looking Ahead Sustained diesel prices at current levels will likely accelerate carrier exits among smaller operators with limited credit access, further tightening capacity and pushing freight costs higher.
