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.

American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index increased 1.4% in January after rising 1.2% in December. In January, the index equaled 114.6 (2015=100) compared with 113.1 in December. “Over the last four months, the tonnage index has increased a total of 3.3%, which is obviously good news,” said ATA Chief Economist Bob Costello. “However, the index is still off 2.8% from the high in March as tonnage plunged 9% in April alone. I continue to expect a nice climb up for the economy and truck freight as we get more economic stimulus and increased vaccination numbers.” Compared with January 2020, the SA index fell 2.1%, which was preceded by a 2.6% year-over-year decline in December. In 2020, the index was 4% below the 2019 average.
