BEHIND THE SHIELD
The national average for on-highway diesel held at $5.64/gal this week — essentially flat week-over-week, but that number requires context. Last week was CVSA International Roadcheck, the 72-hour enforcement blitz that removes thousands of trucks from active service as drivers voluntarily park to avoid inspection risk. Capacity during Roadcheck is artificially constrained. The data that came out of that window does not reflect a softening market — it reflects a market that was already too tight to absorb a 72-hour supply shock. Now that Roadcheck is over, those trucks are back. The freight was never gone.
Regional fuel disparities remain significant: West Coast diesel is at $6.56/gal, the Midwest at $5.82/gal. The Iran conflict continues to inject volatility into crude oil markets, and conditions can shift materially overnight. Every carrier in the country is monitoring the situation closely. Fuel surcharge tables written before Q1 2026 are materially underpriced for today's cost environment — shippers on legacy FSC structures are absorbing the gap in the form of tender rejections.
The dry van load-to-truck ratio has surged to 9.0 — three times the threshold that defines a tight market. The Outbound Tender Rejection Index is hovering near 15%, a level not seen consistently since the post-COVID unwind of 2022. DAT spot rates jumped 11.9% from Q4 2025 to Q1 2026. Dry van all-in rates hit a cycle high of $2.62/mile in early May. Flatbed recorded its eighth consecutive weekly increase, with the L/T ratio reaching a historic 64.4. Reefer is holding at $2.73/mile. The structural picture is unambiguous: over 13,000 carriers exited the market in 2024–25, and that supply is not coming back.
Catalyst 1 — The SCOTUS Broker Liability Ruling: The Supreme Court's unanimous decision in Montgomery v. Caribe Transport II, LLC removes the legal shield that some brokerages relied on in place of rigorous carrier vetting. For brokerages that were already conducting thorough due diligence — reviewing safety scores, insurance certificates, and carrier histories before every tender — this ruling changes very little about how they operate. For brokerages that were not, it changes everything. The practical effect will be uneven: insurance costs will rise across the board (that is almost certain), but the brokerages most exposed are those that used the prior legal framework as a substitute for real vetting standards. Shippers should treat this ruling as a prompt to evaluate their broker's carrier qualification process directly — the answer will tell you a great deal about your actual risk exposure.
Catalyst 2 — The Tariff Front-Load Is Not Demand Recovery: The surge in freight movement accelerating through May 2026 is not the organic demand recovery carriers have been waiting for — it is a tariff front-load. Shippers importing from China, Mexico, and Canada have been scrambling to pull inventory forward before tariff rates lock in or escalate further under the US-China truce, which expires November 10, 2026. The FreightWaves SONAR National Truckload Index is tracking dry van spot rates up more than 20% year over year as of mid-May, with spot load posts up 68% YoY. But this freight is being driven by shipper panic, not structural demand. Once inventory is positioned, new orders will slow and the front-load will unwind — leaving carriers who stretched to capture the surge exposed. Shippers who mistake this window for a recovered market will be caught without coverage when the next tightening cycle hits.
Catalyst 3 — The Looming Driver Qualification Squeeze: Beyond the recent FMCSA non-domiciled CDL rules, large carriers are pushing to mandate hair follicle drug testing for CDL qualification. Because hair testing detects five times more positive results than standard urine testing, this regulatory shift threatens to sideline a significant segment of the existing driver pool. Combined with ongoing carrier bankruptcies and the SCOTUS ruling's effect on carrier vetting, this creates the conditions for a legitimate, structural driver shortage that will keep capacity exceptionally tight and rates elevated well into 2027.
