American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index decreased 1.2% in July after falling 2% in June. In July, the index equaled 109.8 (2015=100) compared with 111.1 in June. “Softness in tonnage over the last few months is due more to supply constraints, rather than a big drop in freight volumes,” said ATA Chief Economist Bob Costello. “Not only are there broader supply chain issues, like semiconductors, holding tonnage back, but there are also industry specific difficulties, including the driver shortage and lack of equipment. For-hire truckload carriers are operating fewer trucks than a year earlier. It is difficult to haul significantly more freight with fewer trucks and drivers. “In addition to these supply issues, retail sales and housing starts, both large drivers of truck freight, retreated in July, although both rose on a year-over-year basis,” he said. June’s reading was revised down to -2% from our July 20 press release. Compared with July 2020, the SA index fell 2.9%, which was the first year-over-year drop since March. In June, the index was flat from a year earlier. Year-to-date, compared with the same seven months in 2020, tonnage is down 0.2%.

Gasoline rose to a two-year high as Tropical Storm Harvey hit the U.S. Gulf coast again after already knocking out a fifth of the nation’s refining capacity. Motiva Enterprises LLC’s Port Arthur refinery, the country’s biggest, was said to be shutting because of severe flooding. The disruption helped send motor fuel as much as 3.3 percent higher in New York, while the resulting reduction in demand from plants hit by the storm kept crude near a five-week low. After drenching Texas, Harvey regained strength over the waters of the Gulf of Mexico and crashed ashore again Wednesday in southwest Louisiana, according to the National Hurricane Center. “The market focus seems to be on the quantity of refinery capacity shut-ins and potential to hit oil demand,” said Giovanni Staunovo, an analyst at UBS Group AG in Zurich.
