Records on an empty stomach

The all-in dry van spot rate slipped in mid-June, to about $3.01 a mile. Pull out the fuel surcharge, though, and the linehaul underneath, the rate carriers actually keep, sits at a record for the week, near $2.37. The headline is easing because diesel is easing, with crude sliding as the Strait of Hormuz looks set to reopen. What carriers are paid to move the truck is not easing. The third quarter turns on which of those two numbers tells the truth.

Diesel's part in this deserves a precise account, because we have argued both sides of it. In March, when the headline index first cleared $3 a mile, we pointed out that the fuel surcharge was doing much of the lifting while linehaul, the rate carriers actually keep, lagged behind. The cycle high was partly a fuel illusion. That is no longer the case. Linehaul has since caught up, and the record now reflects what carriers are paid for the truck, not just what they pass through for the pump. The strength is real. The question for the third quarter is whether it stays real once the fuel that inflated it comes out.

The engine that reverses

Diesel ran to about $5.35 a gallon this spring, up close to $1.90 from a year earlier, after the closure of the Strait of Hormuz pushed crude and refined products higher. The strait carries roughly a fifth of the world's seaborne oil, so when it shut, diesel followed crude up with the usual short lag. Brent crude sat near $105 a barrel through June, and the June Short-Term Energy Outlook expects shipments through the strait to resume during the third quarter, with the ramp back to normal flows running into early 2027. That is a gradual easing, not a cliff. Diesel works lower across the quarter rather than snapping back to where it began the year. Oil markets have already started to price the reopening, and the surcharge that rides on top of every linehaul rate comes down with it.

None of that settles where rates go. Diesel is the loud, visible pressure on capacity, and it is the one about to reverse. It is not the only pressure, and the others do not move with oil.

The other pressures have been thinning the carrier base all year, and none of them tracks the price of oil. States have revoked more than 28,000 non-domiciled CDLs under the new federal rule, which FMCSA expects to push some 194,000 drivers out of the market over time. FMCSA's ELD purge keeps removing devices, with carriers facing an out-of-service date in July. EPA's 2027 emissions standards have pulled truck orders forward and pushed sticker prices up by $15,000 to $30,000, which raises the cost of buying back in. The Supreme Court's broker-liability ruling has brokers screening the marginal carrier out rather than waiting to get sued. DEF climbed alongside diesel, a smaller cost landing on the same operators.

What those share is who they hit. Every one falls hardest on small carriers and owner-operators, the segment that runs closest to breakeven and carries the least cushion. In a normal recovery that segment is also the ceiling on rates. When spot ticks up, sidelined owner-operators buy a truck and come back, capacity floods in, and the rate increase caps itself. That return is what ends supply-driven rallies. This year the door back in is narrower and getting narrower, between higher fuel, a pricier truck, a license under review and a broker who would rather not. Tight is the wrong word for it. The market is being cleared of the capacity that usually puts a lid on a recovery.

So the third quarter sets up as a clean test. Diesel, the removable pressure, falls. The structural pressures stay. If linehaul holds while the pump price drops, the strength was never mostly about fuel, and a cleared market is carrying it. If linehaul fades in step with diesel, it was a surcharge story after all. That is what our dry van linehaul market is built to answer, with the diesel market beside it tracking the input doing the moving.

A record on weak freight

None of this is happening because freight is booming. ATA's tonnage index fell 2% in May, the second straight monthly decline, and its year-over-year gain narrowed to 0.6%, the slimmest of a six-month streak. Cass shipments have spent the year below 2025 levels. The rate strength has come from the supply side the whole way, the case we made in the one-legged recovery, and the spring data did nothing to change it.

Demand is also where the quarter gets complicated. Importers spent the first half of the year pulling shipments forwardahead of tariffs, which leaves an air pocket in the back half as those orders work down through inventory. That pressures volume early in the quarter. Building behind it is the restock those same importers will eventually need, along with the tariff-refund wave that could free working capital for new orders. The order in which those two arrive, the air pocket first and the restock later, is the swing factor for third-quarter freight.

Whichever way demand breaks, a cleared market changes how it lands. With the marginal capacity already gone, the floor under rates no longer sits where it used to. There is less slack to absorb a soft patch and far less to absorb a strong one. If the restock arrives into a market stripped of its re-entry cushion, the response is lopsided. Rates have limited room to fall and a good deal of room to jump.

This is the call, not a certainty, and the case against it is real. The clearing thesis assumes the structural exits hold and demand does not fall further. If freight stays this soft and diesel drops faster than the EIA expects, the marginal operators who were a month from quitting get a reprieve, the capacity that was about to leave stays, and even a thin float can cap a market with no freight to move. A supply-built rally on weak demand is sturdier than a fuel head-fake. It is not bulletproof. What ends it is the same thing that has been missing all year, either enough freight to matter or a diesel drop deep enough to keep the small carrier in the seat.

If structural relief does arrive, it is likelier to come from rail than from owner-operators buying back in. A single-line transcontinental and the freight already moving to intermodal are the pressure valve on a one-to-two-year horizon, not the next quarter. The capacity that left this year is not coming back in time to matter for the third quarter.

What to watch, and what to do

The usual tell for a freight turn is volume. This year volume has been the lagging signal rather than the leading one. The signals worth watching sit on the supply side: net carrier revocations and active authority counts, the tender rejection rate and the spread between spot and contract as contract reprices upward. DAT's 12-month read has contract up 8% and spot up 12%, the spread closing as the paper market catches up to the physical one. Those tell you whether the clearing is holding. The monthly tonnage print will not.

The spread also closes from the contract side. The rejection reports we tracked through the spring bid cycle become higher committed rates at the next round. For shippers still riding broken lanes, the next bid is where the spot increase turns into the contract rate they live with.

For carriers, falling diesel is real relief, and it is easy to size. For an owner-operator getting 6.5 miles to the gallon, a dollar off the pump price is about 15 cents a mile back in the pocket. What it does not do is move the breakeven much. Fuel is around a third of what it costs to run a truck. The rest is the payment, the insurance, the maintenance and your own pay, and none of that falls when crude does.

For shippers, the read runs the other way. Do not build the back half of the budget around fuel-driven rate relief. The surcharge will ease. The linehaul that makes up most of the rate is held up by a capacity story cheaper diesel does not touch. A cleared market is an argument to lock or hedge before a restock arrives and finds no slack waiting.

Cheaper diesel is coming. Broad rate relief mostly is not. The third quarter is where the difference between the two becomes visible, one weekly print at a time.

Your prediction, your reputation.
