The percent difference between the domestic intermodal contract rate per mile (all-inclusive) and the truckload contract rate per mile (all-inclusive) on the same lane (i.e., same origin-destination pair). The Intermodal Savings Index tickers are derived from the SONAR contract rate data described here but with a key difference of these being calculated as all-in rates versus transportation only.
The Intermodal Savings Index is reported in SONAR on a national level and is broken down in two ways:
The tickers are as follows:
Shippers, carriers, intermodal marketing companies and analysts
The intermodal contract indices show the average percent difference between intermodal contract rates and truckload rates on the same lane. The indices, therefore, show the percent savings that shippers might expect to receive on a freight contract for using domestic intermodal rather than truckload. The savings associated with intermodal relative to truckload, which is typically around 10%-15%, is intended to compensate shippers for the typically lower service level associated with intermodal.
The initial reports give the quickest view of the direction of the potential savings while sacrificing a level of accuracy for quicker decision making. The final reports offer a much cleaner view, having the majority of the reports for that time period for validation and historical reporting.
