A Measure of Market Fluctuations in Per-Mile Intermodal Freight Costs

As the nation’s largest payer of freight bills, Cass manages $28 billion annually in freight spend, enabling us to compile meaningful data that serves as an indicator of transportation industry trends. The Cass Intermodal Price Index® is a measure of market fluctuations in U.S. domestic intermodal costs. Cass partners with securities analyst firm Broughton Capital LLC, who provides the analysis we offer each month.

July 2019

After setting an all-time high in March, the Cass Intermodal Price Index has steadily declined sequentially. July continued that trend, falling -0.5% from June. The cost of intermodal shipping is slightly higher (up 1.5%) on a YoY basis and July marked the 34th consecutive month of YoY increases. That said, the weakness in truckload spot pricing and the decline in the price of diesel have weakened pricing power for intermodal. Analyst Donald Broughton predicts, “the YoY results for the Cass Intermodal Index will go negative in October, and may fall negative as early as August or September.”
