The American Trucking Associations' advanced seasonally adjusted For-Hire Truck Tonnage Index fell 3.3 percent in March 2008, after remaining unchanged in February. The not seasonally adjusted index increased 3.8 percent from February to 113.2.
The seasonally adjusted tonnage index equaled 113.4 (2000 = 100) in March, its lowest level since November 2007. Additionally, tonnage contracted 0.2 percent compared with March 2007, marking the first year-over-year decrease in the index since October 2007.
ATA Chief Economist Bob Costello said the latest tonnage reading was a significant setback. “I've been concerned that the recent run-up in tonnage might not be sustainable, and clearly March's figures confirmed that apprehension,” he said. The 3.3 percent drop was the largest month-to-month contraction since August 2006.
Costello continues to forecast a mild recession for the overall economy during the first half of 2008, but noted that March's tonnage drop might suggest the economic contraction could be more severe than previously thought.
