Freight Transportation Services Index
The Freight Transportation Services Index measures the monthly output of the for-hire freight sector, combining trucking, rail, inland and coastal water, air cargo, and pipeline into one chain-weighted index (2000 = 100). Published by the Bureau of Transportation Statistics, it is the authoritative government counterpart to the private Cass index.

Latest reading
As of June 2026, Freight TSI (Freight TSI (2000=100)) stands at 134.9 — down from 135.3 the prior reading, 4.1% below the August 2019 record of 140.7. Freight output tends to peak before recessions and trough during them, so it works as a cycle read — focus on the year-over-year rate to strip out seasonality. Consistent multi-month declines flag weakening demand; compare against the Cass index and industrial production for confirmation. Note the data lands with a 6-8 week lag and excludes company-owned (private) fleets and most parcel delivery. Series history runs from 2000 to present.
