Cass Freight Index 2026: The 42-Month Freight Slump Is Over — What It Means for Your Rates

Cass Freight Index 2026: terminó la caída de 42 meses — y esto pasa con tus tarifas

Por Sultan Freight Editorial6 min de lectura

The Cass Freight Index for August 2026 did something it hasn’t done since January 2023: shipments grew year over year. The index landed at 1.038, up 5.6% from July and 2.1% from a year ago, which ends a 42-month downturn that Cass describes as the longest on record. For shippers and owner-operators across NJ, NY and the Northeast, the Cass Freight Index 2026 reading is more than a statistic — it is the first hard evidence that the freight recession squeezing carrier margins since 2023 has turned.

One month is not a trend, and the same report carries a warning. But the numbers behind it explain why your truckload quote keeps creeping up, so it is worth reading them closely.

What the Cass Freight Index measured in August

Cass builds the index from freight invoices it audits and pays for its shipper clients, so it reflects what shippers actually paid — not asking rates on a load board. According to the Cass Transportation Index Report for August 2026:

MeasureAugust 2026vs. Julyvs. Aug 2025
Shipments index1.038+5.6%+2.1%
Expenditures index3.722+5.8%+18.7%
Truckload linehaul index153.9+0.7%+11.3%

Read the gap between the last two columns. Shipments are up 2.1% year over year, but total spending is up 18.7%. Volume is barely recovering; price is doing the work.

Shipments rose 2.1% year over year. Freight spending rose 18.7%. The recovery so far is a price story, not a volume story.

Why freight spending is outrunning volume

Two forces are behind the gap. The first is fuel: the weekly retail diesel average reached a record $6.285 a gallon on Sept. 14, up 68.1% from a year earlier, according to the Cass September news roundup. That is the first weekly reading above $6 in EIA records going back to 2007, and the number has climbed since — we covered the move to $6.529 in our diesel record shipper capacity briefing.

The second is capacity. Truck supply has been shrinking, and the truckload linehaul index is now up 11.3% year over year. When fewer trucks chase the same freight, rates move even if volume barely does.

The spot market agrees

DAT’s Truckload Market Report for Sept. 13–19 shows the same direction. Rates below are 7-day national averages including fuel surcharge:

EquipmentSpot rate (all-in)Weekly changeLoad-to-truck ratio
Dry van$2.96/mi+4¢11.2
Reefer$3.59/mi+9¢19.1
Flatbed$3.55/mi+6¢40.5

Year over year, DAT reports linehaul rates up 33% for van, 38% for reefer and 29% for flatbed, with truck posts still well below last year’s levels. Flatbed load posts jumped 25% after Labor Day. If you want the difference between the linehaul and all-in numbers explained, see our guide to linehaul vs. all-in rate.

Is the freight recession really over?

Tim Denoyer of ACT Research told Cass that with growth strong even amid a soft job market, and a restock likely beginning as ocean volumes rise and tariff refunds are paid, “the bottom is probably in.” He also cautioned that risks remain elevated, particularly oil prices, inflation and interest rates.

Our read: the direction has changed, but this is a supply-tightening recovery. Carriers are getting paid more mainly because there are fewer of them and diesel is expensive, not because shippers suddenly have far more freight. That matters for how you plan Q4.

What the Cass index does not tell you

A national index is a compass, not a rate quote. Cass reflects what its shipper clients paid across all modes of freight, so it blends contract and spot pricing and averages away regional differences. It says nothing specific about the Newark port area, the I-95 corridor or the box-truck lanes that most NJ/NY shippers actually run. Monthly readings can also be revised, and August’s +5.6% jump over July may partly reflect seasonal restocking rather than a permanent step up.

So use the index for direction and your own lane data for decisions. Pull your last 90 days of tender acceptances by lane: if acceptance is slipping on lanes where your rate sits below the spot market, that is the local version of the national signal.

What NJ/NY shippers should do now

  • Compare your contract rates with today’s spot. If your contract lane sits well below the all-in spot rate, expect more tender rejections as carriers chase better-paying loads.
  • Get the fuel surcharge in writing. Confirm the diesel index, the reset cadence and the base price. A lagging schedule quietly moves cost to the carrier — see how the fuel surcharge lag eats margin.
  • Lock Q4 capacity early. Our NJ/NY Q4 capacity outlook shows what shippers should expect to pay on regional lanes.
  • Vet every new carrier you add. Tight markets bring in unfamiliar names; run the checks in how to vet a trucking carrier before a truck reaches your dock.

For owner-operators

Do not discount your truck to fill a week. Know your all-in cost per mile at $6+ diesel, and price against that number — our profit-per-mile guide walks through the math.

Does the end of the 42-month slump mean the freight recession is over?

It is the strongest signal yet. Cass shipments grew year over year in August for the first time since January 2023, and ACT Research says the bottom is probably in. But it is a single month, and Cass and ACT both flag oil prices, inflation and interest rates as risks.

How much have truckload rates risen in 2026?

Cass’s truckload linehaul index was up 11.3% year over year in August. DAT reports spot linehaul up 33% for van, 38% for reefer and 29% for flatbed year over year in the week of Sept. 13–19.

Are your Q4 contract rates still priced for a market that stopped existing in August?
