American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index increased 2.7% in June after rising 0.3% in May. In June, the index equaled 120.1 (2015=100) versus 116.9 in May.

ATA Chief Economist Bob Costello “Essentially, the market is transitioning back to pre-pandemic shares of contract versus spot market.

“June’s jump tells me a couple of things: first, the transition in the freight market from spot back to contract continues. ATA’s tonnage index is dominated by contract freight, so while the spot market has slowed as freight softens, contract carriers are backfilling those losses with loads from shippers reducing spot market exposure,” said ATA Chief Economist Bob Costello. “Essentially, the market is transitioning back to pre-pandemic shares of contract versus spot market.

“Second, and perhaps equally important, while economic growth is expected to be soft overall in the second quarter, the goods-economy wasn’t as bad as feared,” he said.

May’s increase was revised down from our June 21 press release.
