Executive Summary
The defining story of July is the unwinding of a fuel shock. After the United States lifted its naval blockade of Iran in mid-June, the Strait of Hormuz began reopening to oil traffic (The New York Times, 06/23/26), and the conflict premium that pushed diesel above $5.60/gal in May has drained out fast. U.S. on-highway diesel fell to $4.668/gal for the week ending 06/29/26, an eighth consecutive weekly decline (EIA). TL fuel surcharges eased in step to $0.58/mi (FreightPlus FSC Schedule).
That relief is genuine but incomplete, and it is a cost burden easing rather than a benefit arriving. Diesel remains well above the $3.897/gal pre-blockade baseline (EIA, week ending 03/02/26), so carriers and shippers are still absorbing higher fuel than they were four months ago, roughly $78 more per 600-mile load. The recovery in Gulf shipping is also fragile: a backlog of 500 to 600 vessels remains, traffic is a fraction of pre-conflict levels, and Iran and Oman are discussing transit fees (The New York Times, 06/23/26). EIA's June outlook still modeled the strait as closed in the near term (EIA STEO, June 2026); the on-the-ground reopening is running ahead of the official forecast.
Underneath the fuel move, the physical market is tight. Van load-to-truck ratios sit well above year-ago levels, spot linehaul rose again into the July 4 holiday week, and DAT contract rates are running near 10% over 2025 (DAT). Manufacturing is still expanding, with ISM PMI at 53.3% in June (ISM, June 2026), and truck tonnage rose 2.7% in June (ATA, June 2026). Falling fuel is landing on a firming freight market, not a soft one. For the structural picture behind capacity, the June 2026 report laid out the Montgomery ruling and the CDL/ELD enforcement stack that continues to bite.
Diesel and Fuel Surcharges
U.S. on-highway diesel averaged $4.668/gal for the week ending 06/29/26, down $0.164 from the prior week and down $0.971 from the May 11 reading of $5.639/gal (EIA), an eighth straight weekly decline. The driver is geopolitical: with the U.S. naval blockade of Iran lifted and the Strait of Hormuz reopening to crude traffic (The New York Times, 06/23/26), the risk premium in oil has receded and diesel has followed. At these levels diesel is still a cost burden on both carriers and shippers, but the direction is relief on operating costs.
Eight consecutive weekly declines · $5.639 peak on 05/11 (blockade-era) down to $4.668 on 06/29, a $0.971 pullback as the Strait of Hormuz reopened.

At $4.668/gal, the FreightPlus TL fuel surcharge computes to $0.58/mi and the IMDL surcharge to 34% of linehaul (FreightPlus FSC Schedule), down from $0.61/mi the prior week. Each $0.06 move in diesel steps the TL schedule by $0.01/mi, so the eight-week slide from $5.639 to $4.668 has pulled the TL FSC down $0.16/mi. As a separate contract component, the FSC is doing exactly what it should: passing the fuel decline through on the schedule's cadence without disturbing linehaul.
Fuel Cost Impact · vs. Pre-Blockade Baseline
Baseline: $3.897/gal (week ending 03/02/2026, last EIA reading before the Strait of Hormuz blockade), TL FSC $0.45/mi. Impact column shows added per-load fuel cost vs. that baseline over a standardized 600-mile load.
| Week Ending | Diesel ($/gal) | TL FSC ($/mi) | Delta vs. Baseline | Impact / 600-mi Load |
|---|---|---|---|---|
| 2026-05-11 | $5.639 | $0.74 | +0.29 | +$174.00 |
| 2026-05-18 | $5.596 | $0.74 | +0.29 | +$174.00 |
| 2026-05-25 | $5.523 | $0.73 | +0.28 | +$168.00 |
| 2026-06-01 | $5.350 | $0.70 | +0.25 | +$150.00 |
| 2026-06-08 | $5.210 | $0.67 | +0.22 | +$132.00 |
| 2026-06-15 | $5.059 | $0.65 | +0.20 | +$120.00 |
| 2026-06-22 | $4.832 | $0.61 | +0.16 | +$96.00 |
| 2026-06-29 | $4.668 | $0.58 | +0.13 | +$78.00 |
Even after eight weeks of decline, carriers and shippers are still paying more for fuel than before the blockade. At $0.58/mi TL FSC, a 600-mile load carries $78 more in fuel surcharge than at the $3.897/gal baseline, down from the $174 peak in the weeks ending 05/11 and 05/18 when diesel sat near $5.60/gal. The burden is shrinking, not gone: the impact has fallen $96 per load off its peak but remains firmly positive. This is relief on an operating cost, not a windfall.
Fuel Forecast: Then vs. Now
The fuel forecast has swung hard with the strait. Bank of America raised its 2026 Brent average on the Hormuz disruption; the reopening now pulls the other way.
| Metric | Prior Forecast | Current Forecast | Direction |
|---|---|---|---|
| Brent crude · 2026 avg | $61/bbl BofA, prior view | $77.50/bbl BofA Global Research | ▲ Raised on Hormuz |
| Brent crude · Jun-Jul avg | strait-open basis | ~$105/bbl EIA STEO, Jun 2026 | ▲ Conflict premium |
EIA's June outlook assumed the strait stayed closed in the near term, with traffic resuming in Q3 and pre-conflict levels not returning until early 2027 (EIA STEO, June 2026). BofA sees Brent reverting toward $65 in 2027 as flows normalize (BofA Global Research). The June 23 reopening (The New York Times) is running ahead of the closed-strait assumption, which is why retail diesel at $4.668/gal is already sliding toward the annual-average path faster than the June forecast implied.
Top Corridor Spotlight · Peak Produce + Post-Roadcheck
The peak-produce and post-Roadcheck basket tracks four reefer-heavy corridors that define midsummer capacity. Moves are shown as month-over-month and year-over-year changes from Greenscreens network-rate predictions for a July 7 pickup, with a model confidence score per lane.
| Lane | Distance | MoM | YoY | Linehaul YoY | Confidence |
|---|---|---|---|---|---|
| Yakima WA → Chicago IL | 1,955 mi | -0.1% | +28.5% | +27.9% | 95/100 |
| Salinas CA → Chicago IL | 2,253 mi | -2.1% | +43.5% | +45.7% | 72/100 |
| McAllen TX → Detroit MI | 1,699 mi | +19.3% | +60.9% | +68.5% | 69/100 |
| Atlanta GA → Boston MA | 1,125 mi | -4.6% | +59.7% | +63.6% | 73/100 |
Every lane in the basket is up double digits year-over-year, confirming a broadly tighter market than mid-2025. McAllen TX to Detroit MI leads at +60.9% YoY, with linehaul ex-fuel up +68.5%; that figure warrants context: the Midwest-inbound lane has run hot since spring on cross-border produce pulling equipment north and constrained maquiladora-corridor capacity. The West Coast lanes tell the month-over-month story: Salinas CA to Chicago IL eased 2.1% MoM as the California deal shifted, and Yakima WA to Chicago IL remained flat (-0.1% MoM), both normal seasonal timing rather than demand loss.

Supply Side: Capacity Stays Tight as Fuel Relief Arrives
The supply side is where this market's tension lives. Fuel is easing, but trucks are not getting easier to find.
Load-to-Truck Ratio · DAT Public Weekly
| Equipment | Current LTR (wk 07/04) | Week 06/27 | June Avg |
|---|---|---|---|
| Van | 10.87 | 12.88 | 10.61 |
| Reefer | 21.30 | 24.47 | 19.97 |
| Flatbed | 42.05 | 56.94 | 59.37 |
Van load-to-truck ratio was 10.87 for the week beginning 07/04/26, down from 12.88 the prior week (DAT via TheTrucker.com), a holiday-week dip as carriers parked for Independence Day rather than a loosening of the market: DAT load posts still ran roughly 35% above year-ago levels. Read the signal by direction, not by the absolute. DAT changed its LTR methodology in 2025, so today's numbers are not comparable to pre-2025 rules of thumb, and the direction remains tight. For contract-heavy shippers who feel insulated from spot: the spot LTR is the leverage gauge your carriers bring to every renewal. When spot tightens, primary carriers negotiate contract rates from strength, so this metric shapes your bid outcomes even when you never touch the spot board.
Driver and fleet capacity. Small-carrier bankruptcies continued through the first half of 2026 as the freight recession that began in 2022 ground on (FreightWaves; altLINE, 2026). STG Logistics restructured about $1.2 billion in debt in January, and regional carriers such as Standard Forwarding wound down. Each exit pulls trucks out of the network and firms the capacity floor under rates.
Spot pricing. DAT reported national van spot linehaul at $2.49/mi for the July 4 holiday week, up 7 cents week over week, with spot rates rising 3 to 10 cents across all three equipment types even as volumes dipped for the holiday (DAT via TheTrucker.com). May spot levels were already sharply higher year-over-year: van $2.89, reefer $3.35, and flatbed $3.65, a record (DAT).
Regulatory. FMCSA published three deregulatory final rules on June 22, effective July 22, removing the CDL self-reporting requirement, the in-cab ELD operator's-manual requirement, and a license-plate-lamp rule (FreightWaves, June 2026). None touch hours-of-service, and the net capacity effect is marginal, but they trim compliance friction at the edges.
Structural. The Supreme Court's May 14 ruling in Montgomery v. Caribe Transport II established that freight brokers can face state-law negligent-selection claims (DLA Piper; Logistics Management, 2026). Near-term operational change is limited, but it raises broker compliance cost and carrier-vetting rigor, a slow structural pressure on the industry cost base. See the June 2026 report for the full ruling context, and the FreightPlus Carrier Risk Assessment for the vetting workflow this ruling now makes table stakes.
Capacity Calendar · Next 60 Days
Watch list for the next 60 days. Source: FreightPlus internal capacity calendar.
| Window | Event | Expected Capacity Impact |
|---|---|---|
| Through late July | Produce Season | Reefer demand surges nationally; competition for equipment in Southeast, Southwest, and West Coast growing regions; dry van and flatbed feel indirect pressure as reefer draws equipment away. |
| Mid-July to September | Back-to-School Season | Retail, apparel, and school-supply demand builds; retail corridors tighten; parcel-heavy lanes pressured as consumer fulfillment volumes accelerate. |
| Through October | Construction Season | Flatbed tightens on lumber, steel, and aggregates; infrastructure projects draw equipment from general freight corridors. |
| August onward (peak Aug-Oct) | Hurricane Season | Gulf Coast and Southeast corridor vulnerability; storm prep and recovery tie up capacity; FEMA and relief freight can displace thousands of trucks with minimal notice. |
| Wks 35-36 · Aug 31-Sept 7 | Labor Day | Long weekend disrupts flow; driver home time; displacement and retail build-up in the recovery window. |
| Wk 39 · late September | End of Quarter Rush | Shippers rush to meet quarter-end targets; carrier demand spikes in the final week; rate pressure builds on high-volume corridors. |
Demand Side: Manufacturing Expands, Freight Firms
Demand is holding up. ISM's Manufacturing PMI registered 53.3% in June, a sixth straight month of expansion, though down 0.7 point from May (ISM, June 2026). New orders stayed firm at 56%, while the prices index fell sharply from 82.1 to 73.0, its largest single-month drop since July 2022, a direct read-through of the fuel and commodity relief from the strait reopening.
Freight volumes confirm the strength. ATA's truck tonnage index rose 2.7% in June (ATA, June 2026), extending a turnaround, and DAT load posts ran roughly 35% above year-ago levels even in the holiday-shortened first week of July (DAT via TheTrucker.com). The pricing reset has moved from spot into contract: DAT aggregate contract rates are running near 10% over 2025.
For shippers, the contract-versus-spot gap is closing from the spot side up. When spot linehaul rises toward contract, carriers gain leverage in renewals, and that dynamic reaches even primarily-contract shippers through their next bid cycle. The demand backdrop does not argue for waiting out the tightness in hopes it fades on its own.
Risk Factors
- Capacity attrition. Small-carrier bankruptcies continue even as the freight recession fades, as years of thin margins finally catch up with weaker operators (FreightWaves); every exit removes trucks and firms the rate floor.
- Produce and construction overlap. Reefer produce season runs through July and flatbed construction season through October (FreightPlus capacity calendar), tightening dry van indirectly.
- Fragile fuel relief. The strait reopening is fragile; any Iranian interference could collapse transit again (The New York Times, 06/23/26), re-spiking diesel and FSC.
- Broker-liability regime. The Montgomery ruling (05/14/26) raises broker risk and vetting cost (DLA Piper), which can flow into rates as exposure gets priced in.
- Crude reverting to surplus. BofA sees Brent falling toward $65 in 2027 as the strait normalizes (BofA Global Research); lower fuel eases FSC and softens all-in pricing.
- Demand decelerating. ISM PMI slipped to 53.3% in June from 54.0%, with production down (ISM, June 2026); freight demand growth is cooling at the margin.
- Spot mean-reversion. DAT spot volume has run about 35% above year-ago; a normalization as post-blockade urgency fades would pull spot rates down.
- Deregulatory easing. FMCSA's three June 22 deregulatory rules (effective 07/22/26) trim compliance friction (FreightWaves), a modest tailwind to available capacity.
FreightPlus Position
Fuel. Diesel is easing but still elevated. Keep the FSC working as a separate contract component, not folded into linehaul. The choice between a weekly-reset and a monthly-lag FSC schedule matters more in a fast-moving market than the headline rate: at current volatility, monthly-lag contracts risk roughly a $0.05/mi billing mismatch on high-mileage lanes when diesel moves this fast. Model the mechanism at a realistic annual-average diesel, not at today's spot reading.
Spot rates. Spot linehaul is climbing and contract is following (DAT). We read the strength as capacity-driven rather than demand-driven, so it is real but not guaranteed durable. Hold spot exposure where flexibility matters, and convert to contract on lanes where you need certainty on tight equipment.
Capacity strategy through Q3. Produce, construction, and hurricane season overlap through the quarter (FreightPlus capacity calendar). Line up committed capacity now on reefer-adjacent and flatbed-competing dry van lanes. FreightPlus can develop a capacity contingency plan for high-exposure lanes ahead of the Labor Day and quarter-end windows.
Contract bid timing. For RFPs landing this quarter, model the FSC mechanism choice (weekly-reset vs. monthly-lag) at a realistic annual-average diesel rather than pricing diesel into linehaul. Separate what carriers earn ex-fuel from the surcharge cadence: the linehaul number should reflect capacity and lane economics; the FSC schedule should reflect fuel. Conflating the two is where mid-market bids go wrong.
Bottom Line
Fuel relief is real but partial and fragile. Diesel has fallen eight straight weeks to $4.668/gal as the Strait of Hormuz reopened, but a 600-mile load still carries $78 more in fuel surcharge than before the blockade, and the reopening could reverse on any Iranian interference (The New York Times, 06/23/26).
The capacity market is tight independent of fuel. Van LTR remains well above year-ago, spot linehaul is rising, contract is near 10% over 2025 (DAT), and small-carrier attrition continues. Do not let falling diesel disguise a firming rate floor.
Separate fuel from freight in every contract conversation. Manage the FSC as its own mechanism, weekly-reset or monthly-lag, and price linehaul on capacity and lane economics. If you remember three things this month: fuel is easing but still a burden, capacity is tight, and the FSC schedule is a lever you set deliberately.
