Cass Freight Shipments: Latest Reading, Historical Chart & Investor Guide

Indicator Snapshot

What Cass Freight Shipments Measures

Cass Freight Index: Shipments measures North American freight shipment volumes. The indicator is published by Cass Information Systems on a monthly basis and is one of the primary datasets used by investors and economists to monitor this area of the economy.

An index of the volume of freight moved by North American shippers, built from the freight invoices Cass processes for its clients and indexed to a 1990 base equal to 100. It is published in seasonally adjusted and unadjusted forms and counts shipments rather than dollars.

Why Investors Watch Cass Freight Shipments

Shipment volume tracks the physical movement of goods, so analysts watch it as a cross-check on industrial production, retail inventories and trucking and rail demand. Investors in transport and logistics firms use it alongside the expenditure and rate series in the same report.

The indicator's impact on financial markets depends on multiple factors: whether the reading was expected, the current economic regime, central bank policy stance, and investor positioning. A single data point is rarely sufficient to draw firm conclusions.

How Cass Freight Shipments Is Calculated

Cass audits and pays freight bills for large shippers, and the index aggregates the number of shipments in that transaction stream each month, expressed relative to the 1990 base. Because it reflects one processor's client base rather than a census of all freight, it is a sample-based indicator of volume.

The official methodology documentation from Cass Information Systems describes the full calculation process including sample design, weighting and revision procedures.
