DAT: Price pressures build as available capacity tightens

With diesel prices surging to $5.375 per gallon—the highest weekly national average since late 2022—the cost shock appeared to tighten capacity during the week of March 22-28: truck posts fell across all three equipment types, with dry van, reefer, and flatbed each reaching their lowest Week 13 truck-post counts in at least 10 years of DAT data. Fewer trucks helped push rates higher across the board.

Market analysis from Dean Croke, Industry Analyst, DAT Freight & Analytics

Fuel is up $1.31 per gallon over the past three weeks, but spot linehaul rates are holding steady. The gap between rising fuel costs and flat spot rates is worth watching.

Truckers are responding to fuel prices by cutting deadhead miles, looking for lighter loads, and slowing down. At current diesel prices, slowing from 75 to 65 mph saves roughly 8 to 9 cents per mile in fuel—the equivalent of a significant per-mile pay raise without hauling a single extra load.

Carriers are also sitting on the sidelines or declining unprofitable loads, which for brokers increases the urgency of having deep carrier relationships rather than relying on transactional capacity.

The Manufacturing PMI jumped into expansionary territory this year, and New Orders—a key indicator for freight volumes—was a big component. If PMI growth continues, it would mean a fuel shock is hitting the market just as freight volumes are recovering, a situation that could keep rates elevated even if fuel moderates.

The Dallas Fed said Texas factory activity continued to rise in March, but at a slower pace than the previous month, according to business executives responding to the Texas Manufacturing Outlook Survey. The production index, a measure of state manufacturing conditions, fell six points to 6.8, a reading suggestive of a below-average pace of output expansion.
