Dry Van Spot Rates Are Rising While Volumes Slide. Routing Guides Need a Stress Test.

Dry van spot rates are moving in a direction that should make shippers uncomfortable.

FreightWaves reported that the U.S. Bank Freight Payment Index Rates Edition showed dry van spot rates up 31% year over year in May 2026. That is a sharp move in any freight market. It is more important because it is not showing up alongside a clean demand boom.

Logistics Management reported that DAT's May Van Truckload Volume Index fell to 233, down 9% from April and 8.3% from a year earlier. Reefer TVI dropped 10% sequentially and 15.7% annually, while flatbed TVI fell 14% from April. Volumes were sliding, but spot rates kept climbing.

That combination deserves attention. It suggests the truckload market is not simply recovering on broad demand strength. It is exposing lane-level fragility.

Fewer Loads Can Still Cost More

Transportation teams often read lower volume as relief. If there are fewer loads in the market, the assumption is that carriers should have more capacity and shippers should have more pricing power. That logic works when capacity is evenly available, carriers are financially stable, and routing guides are current.

Those assumptions are shaky.

A soft-volume environment can still produce expensive spot exposure when capacity disappears from specific lanes, driver availability shifts, small carriers exit, regional weather disrupts balance, or primary carriers decide certain commitments no longer make sense at the contracted rate. The shipper may not feel a market-wide shortage. It may feel a Tuesday pickup failure in Ohio, a Friday reefer gap in Georgia, or a dry van lane where the backup carrier has quietly stopped accepting tenders.

The DAT numbers show why this matters. If the Van TVI is down 9% month over month and 8.3% year over year, but dry van spot prices are still up sharply, then lower demand is not protecting every lane. It may only be masking how brittle individual routing guides have become.

The Routing Guide Is the Early Warning System

A routing guide is supposed to translate procurement strategy into daily execution. It says which carrier should receive the tender first, who comes next, what rate applies, which service rules matter, and when the load should escalate.

In a stable market, shippers can afford to review routing-guide health periodically. In a volatile market, that cadence is too slow. The guide can look fine in a quarterly bid file while failing in daily operations.

The first signal is tender acceptance. If primary-carrier acceptance starts falling on a lane, the guide is weakening before costs show up in finance. The second signal is time to cover. A load that still gets covered but takes six calls, three re-tenders, or an afternoon of dispatcher attention is already more expensive than the contracted rate suggests. The third signal is backup depth. If the second and third carriers are accepting only selectively, the guide has less resilience than the spreadsheet says.

Spot exposure is the fourth signal. It is the one everyone notices, but by then the freight team is already paying the market to solve a control problem.

Budget Risk Starts Before the Invoice

Truckload rate volatility becomes a finance problem when the transportation budget only sees the invoice, not the operating pattern that created it.

If spot rates are up 31% year over year, a handful of uncovered dry van lanes can move the budget quickly. The problem is not just the rate on one emergency load. It is the repeat pattern: rejected tenders, late escalations, manual brokerage intervention, accessorial exposure, missed appointments, and customer-service pressure that forces the team to keep paying up.

Logistics teams need budget triggers that fire before the month closes. A lane should not wait for a formal reforecast if primary acceptance drops below a threshold, average tender depth increases, spot usage crosses a weekly percentage, or actual cost per mile breaks the planned band. Those signals should reach procurement, finance, and operations while there is still time to change behavior.

The wrong response is to treat every spot move as an isolated exception. The better response is to classify the lane. Is this a seasonal surge, a carrier-performance issue, a contract-rate mismatch, a facility dwell problem, an equipment imbalance, or a network-design issue? Each cause has a different fix.

Stress Testing Needs to Be Practical

Routing-guide stress testing does not need to become a months-long consulting exercise. It should be a regular operating review built around the lanes most likely to hurt service or budget.

Start with the lanes where spot usage is rising despite flat or lower volume. Those lanes are telling the truth first. Then review primary-carrier acceptance, tender depth, rate variance, dwell time, pickup-day concentration, appointment constraints, and backup-carrier response. A carrier that accepts 95% of tenders on Monday but 55% on Friday is not a stable primary for a Friday-heavy lane.

Next, compare contracted rates with current spot exposure. If the gap is large and acceptance is falling, the guide may be underpriced. If the spot rate is high but acceptance is still strong, the contract is working and should be protected. If both contract and spot coverage are poor, the lane may need a structural change: different pickup windows, pooled freight, alternate facility routing, intermodal evaluation, or a mini-bid.

Finally, decide escalation rules before the load fails. Which lanes can tolerate later coverage? Which customers require earlier escalation? Which backup carriers are approved for high-value freight? Which loads should never be sent to spot without manager approval? Which budget owners need notification when a lane crosses its cost trigger?

The point is to make the routing guide an active control, not a static procurement artifact.

Why This Is a TMS Problem

The harder part is that the data usually lives in too many places. Contract rates sit in procurement files. Tender outcomes live in the TMS. Carrier notes sit in email. Budget variance appears in freight audit. Facility dwell may be tracked by operations. Customer impact shows up in service dashboards.

That fragmentation is why teams miss the pattern until the invoice arrives.

CXTMS helps logistics teams keep routing-guide health inside the transportation workflow. Tender acceptance, backup-carrier readiness, spot exposure, budget triggers, shipment exceptions, carrier performance, and lane-level cost variance can be connected to the freight decisions teams make every day. If dry van spot rates are rising while volumes slide, the answer is not to wait for the next bid cycle. It is to stress test the lanes that are already showing strain.

If your routing guide is starting to crack under spot-rate pressure, schedule a CXTMS demo to see how CXTMS helps teams catch tender, carrier, and budget risk before spot exposure becomes uncontrolled.
