Building Networks That Can Adapt When the Market Turns
| TL;DR SONAR data shows a truckload market that’s turned sharply in carriers’ favor — tender rejections hit 17.64% in June (highest since March 2022), spot rates set an all-time high of $3.78/mile, and the spot-to-contract spread flipped positive for the first time since 2021. Shippers who built optionality — alternate carriers, modes, facilities, geographies, and procurement triggers — before this shift are absorbing it. Shippers who didn’t are discovering their backup plans only existed on paper. |
Most transportation programs are built for efficiency: the lowest-cost carrier, the tightest routing guide, the preferred mode. That works — until the assumption underneath it breaks. In 2026, a lot of assumptions broke at once.
The Market Just Reset
The numbers are stark. SONAR’s Truckload Rejection Index (STRI.USA) climbed to 17.64% on June 21 — its highest level since March 2022 — and has held near 16% since. The National Truckload Index (NTI.USA) set an all-time high of $3.78 per mile on June 28. And the spot-to-contract spread (RATES12.USA) widened to roughly +$0.51 per mile, its highest level since the 2021 capacity crisis — reversing a spread that had run negative continuously since early 2022.
Translation: contracted freight is getting rejected more often, and when it is, recovering it on the spot market now costs more than the contract rate, not less. That’s a direct, measurable cost that didn’t exist twelve months ago.
Efficiency and Optionality Are Different Problems
Efficiency asks: what’s the best way to move this freight right now? Optionality asks: what do we do when that stops working? A transportation program can be highly efficient — lowest cost, tightest routing guide — and still be fragile if one carrier, mode, facility, or region is the only workable path.
The report breaks this into six dimensions:
- Carrier optionality — a tested tender waterfall (primary, secondary, tertiary) with live volume on every tier, not backup carriers that exist only on paper
- Modal optionality — the ability to shift freight to intermodal, LTL, or spot when the economics favor it (intermodal savings vs. van rates just hit 52%, the widest gap in the index’s history)
- Geographic optionality — alternate gateways, origins, and DCs so one constrained region doesn’t strand the whole network
- Facility optionality — flexible appointment windows and drop-trailer capability, since carriers reject the freight that doesn’t fit their operations before they reject anything else
- Procurement optionality — trigger-based lane reviews instead of one calendar-locked annual bid
- Network optionality — the coordinating layer that turns separate alternatives into an actual, executable response during a disruption
The Myth of the Backup Carrier
A carrier sitting in a routing guide with no live freight isn’t optionality — it’s a name on a list. When the primary rejects, that “backup” behaves like a brand-new provider: no current rate, no operational familiarity, no relationship. Real optionality requires carriers, modes, and facilities to be tested before they’re needed, which means the best time to build it was months ago — and the second-best time is now.
What This Means Right Now
Every one of the report’s market signals is pointing the same direction at once: capacity contracting near record speed (LMI Transportation Capacity at 30.80, near a record low) while prices expand near record strength (LMI Transportation Prices at 96.0 in May, the highest reading in the index’s history). That combination is the textbook definition of a market that’s moved decisively in the carrier’s favor.

FAQ
What is transportation optionality?
Transportation optionality is the ability to shift among multiple viable carriers, modes, facilities, geographies, and procurement strategies when market conditions change, rather than being dependent on a single path that can fail all at once.
Why is truckload capacity tightening in 2026?
SONAR data shows tender rejections (STRI.USA) reaching their highest level since March 2022, alongside record spot rates and a spot-to-contract spread that turned positive for the first time since 2021 — driven by a combination of driver-pool enforcement activity, tariff-driven import timing, and broker-liability-driven carrier consolidation.
What is a tender waterfall?
A tender waterfall is a defined sequence of primary, secondary, and tertiary carriers a load moves through automatically when the option ahead of it rejects. It only works if every tier carries live volume and current rates — a carrier with no freight has no reason to prioritize the shipper when it’s needed.
Should shippers convert freight to intermodal right now?
The environment favors looking: the Intermodal Contract Savings Index (IMCSI.USA) hit 31.52% in mid-2026, the widest spread in its history. But the national index is a directional signal, not a lane-level decision — actual conversion candidates need to be validated against lane-specific intermodal and van benchmarks, transit-time tolerance, and rail ramp access.
What is SONAR’s Lane Score?
Lane Score measures how favorable or difficult a specific origin-destination pair is for a shipper, ranging from lanes where carriers compete for freight (favorable) to lanes where carriers can select freight and alternatives are scarce (difficult). Low-scoring lanes should get the earliest carrier, modal, and contingency review.
