American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index rose 2.1% in June after increasing 1.2% in May. In June, the index equaled 116.5 (2015=100) compared with 114.1 in May.

“While the tonnage index increased in both May and June, it remains in recession territory,” said ATA Chief Economist Bob Costello. “The index continues to fall from a year earlier and is off 1.9% from its recent peak in September 2022. A multitude of factors have caused a recession in freight, including stagnant consumer spending on goods, lower home construction, falling factory output, and shippers consolidating freight into fewer shipments compared with the frenzy during the goods buying spree at the height of the pandemic. However, the magnitude of the year-over-year declines is improving, perhaps pointing to a bottom in the freight market.”

May’s increase was revised lower from our June 20 press release.

Compared with June 2022, the SA index decreased 0.8%, which was the fourth straight year-over-year decrease. In May, the index was down 2.4% from a year earlier.

The not-seasonally adjusted index, which represents the change in tonnage actually hauled by the fleets before any seasonal adjustment, equaled 120.8 in June, 1.8% above the May level (118.7). In calculating the index, 100 represents 2015. ATA’s For-Hire Truck Tonnage Index is dominated by contract freight as opposed to spot market freight.

Trucking serves as a barometer of the U.S. economy, representing 72.6% of tonnage carried by all modes of domestic freight transportation, including manufactured and retail goods. Trucks hauled 11.46 billion tons of freight in 2022. Motor carriers collected $940.8 billion, or 80.7% of total revenue earned by all transport modes.

ATA calculates the tonnage index based on surveys from its membership and has been doing so since the 1970s. This is a preliminary figure and subject to change in the final report issued around the 5th day of each month. The report includes month-to-month and year-over-year results, relevant economic comparisons, and key financial indicators.
