DAT iQ ‘Signal’ Report Points to Rising Freight Rates, Shrinking Capacity, and Carrier Gains

Why It Matters

Higher freight rates and shrinking capacity pressure shippers’ budgets and force renegotiation of contracts, while carriers gain pricing power across key lanes.

Key Takeaways

• Dry van spot rates rose 21% YoY
• Contract rates up 4.2% annually, carriers gaining
• NRD positive across all modes, indicating premium contracts
• Shippers delaying bids, risking higher future costs
• Forecast predicts 8-12% rate increase next year

Pulse Analysis

The DAT iQ March Signal Report confirms that U.S. truckload markets are tightening after a prolonged lull, with dry‑van spot rates jumping 21% year‑over‑year and temperature‑controlled rates up 13% in the first quarter. The New Rate Differential (NRD) turned positive across dry van (+4.2%), reefer (+3.9%) and flatbed (+5.4%), signaling that new contracts are being signed at premiums to expiring agreements. Intermodal also posted a modest NRD of +1.6% and its highest Contract Rate Index since October 2023, though tariff uncertainty continues to weigh on that segment. This marks the strongest three‑month spot‑rate surge since spring 2020 and indicates carriers are finally capturing higher pricing power.

Shippers, however, are reacting cautiously. Fuel price volatility and the unfolding Iran conflict have inflated spot costs by roughly 20% YoY, prompting large retailers to postpone bid events and cling to existing contracts rather than lock in uncertain rates. Approximately 30% of a shipper’s freight spend has risen by 50%, straining budgets and forcing many to delay long‑term routing‑guide updates until the market stabilizes post‑spring. Despite spot surges, paid contract rates remain flat, creating tension that could eventually lift contract pricing once spot volatility eases.

DAT’s 12‑month outlook projects dry‑van contract rates to rise 8% and spot rates 12%, suggesting the window for favorable pricing may already be closed for most shippers. Companies that wait beyond the next quarter risk paying higher premiums as spot rates remain elevated and eventually pull contract rates upward. Strategically, firms should evaluate short‑term hedging, diversify mode choices, and accelerate negotiations to mitigate the cost impact of a tightening capacity environment. Analysts view this tightening as a bellwether for broader supply‑chain inflation, potentially prompting carriers to invest in capacity and technology to capture premium lanes.
