Cass: TL rates jump 11% in August, freight shipments turn positive
Truckload linehaul rates jumped 11.3% YoY in August 2026 — the largest spike since June 2022 — while freight shipments turned positive for the first time in 42 months, per Cass Information Systems. Total freight expenditures surged 18.7% YoY, driven by higher contract rates and diesel prices up 46% YoY.
After 42 months of freight deflation absorbing supply chain costs, the cycle has turned — sellers who built margin models on cheap trucking now face structural cost pressure as both contract rates and diesel normalize upward simultaneously.
Rising contract rates hitting carriers will flow downstream to sellers within 1-2 quarters as 3PLs and carriers reprice agreements — brands on negotiated shipping contracts should audit renewal dates now. If you're relying on spot rates for flexibility, that window is closing as contract rates increasingly outpace spot.

Full Coverage
Truckload linehaul rates surged again in August while shipment counts turned positive for the first time in three and a half years, according to data from Cass Information Systems. Cass’ TL linehaul index, which tracks rates excluding fuel and accessorial surcharges, jumped 11. 3% year over year during the month. The index was up 70 basis points from July.
August marked 20 consecutive y/y increases and the largest since June 2022. The linehaul index includes for-hire spot rates but is historically heavily weighted to contract rates. “The sequential increase is in line with expectations and as indicated by the spot market,” the Monday report said.
“Even as spot rates slow with modest sequential declines, the much larger contract market is adjusting higher.” SONAR: Van Contract Rate Per Mile Index (VCRPM1. USA) for 2026 (blue shaded area), 2025 (yellow line), 2024 (green line) and 2023 (pink line).
The index shows a 7-day moving average of the initial reporting of dry van contract rates without fuel or accessorial charges. To learn more about SONAR, click here. SONAR: National Truckload Index (linehaul only – NTIL. USA) for 2026 (blue shaded area), 2025 (yellow line), 2024 (green line) and 2023 (pink line).
The NTIL is based on an average of booked spot dry van loads from 250,000 lanes. The NTIL is a seven-day moving average of linehaul spot rates excluding fuel. Rates remain significantly higher on a y/y comparison in September. Freight shipments recorded by Cass (NASDAQ: CASS) increased 2. 1% y/y, which was the first y/y increase after 42 months of declines.
Shipments were 5. 6% higher sequentially in August (up 5% seasonally adjusted). All domestic transportation modes are included in the index, but TL accounts for over 50% of shipments, with less-than-truckload representing approximately 25%. Road-to-rail conversion has weighed on the trucking-centric dataset in recent months as fuel prices have surged.
If normal seasonal shipping patterns hold through September, the index would increase approximately 1% y/y, the report said. August 2026y/y2-yearm/mm/m (SA)Shipments2. 1%-7. 4%5. 6%5. 0%Expenditures18. 7%18. 3%5. 8%6. 0%TL Linehaul Index11. 3%12. 6%0.
7%NMTable: Cass Information Systems (SA – seasonally adjusted) Cass’ expenditures index, which measures total freight spend including fuel, surged 18. 7% y/y in August and was up 5. 8% from July (plus-6% seasonally adjusted). The positive y/y inflection in shipments drove the dataset higher, along with higher diesel prices (up 46% y/y and 10% sequentially).
Citing elevated risks to consumer spending, the report calls for tepid freight demand moving forward. “With economic growth strong even amid a soft job market, and a restock likely beginning with ocean volumes rising and tariff refunds happening, the bottom is probably in,” the report said. “While likely modest, freight growth should continue.”
Data used in the indexes comes from freight bills paid by Cass, a provider of payment management solutions. Cass processes $37 billion in freight payables annually on behalf of customers. Why it matters? August data from Cass Information Systems highlights a continued escalation in TL contract rates even as demand remains cool.
The dataset confirms the impact strict regulatory enforcement is having on non-compliant capacity.
