ARLINGTON, Va. (Aug. 22, 2013) — The American Trucking Associations' advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index slipped 0.4 percent in July after edging 0.1 percent higher in June.
The ATA said June's increase was the same as the association reported on July 23. The latest drop was the first since April. In July, the SA index equaled 125.4 (2000=100) vs. 125.9 in June—which hit the highest level on record since the organization has calculated results. Compared with July 2012, the SA index increased 4.7 percent, which is robust, according to the ATA, although it was the smallest year-over-year gain since April. Year-to-date, compared with the same 2012period, the tonnage index is up 4.7 percent.
The not seasonally adjusted index—which represents the change in tonnage actually hauled by fleets before any seasonal adjustment—equaled 129.6 in July, which was 3 percent above the previous month (125.9).
ATA Chief Economist Bob Costello explained that "after gaining a total of 2.2 percent in May and June, it isn't surprising that tonnage slipped a little in July.
"The decrease corresponds with the small decline in manufacturing output during July reported by the Federal Reserve last week."
