What is the Logistics Managers' Index (LMI) and what do the July readings tell us?

The LMI is a monthly diffusion index where readings above 50 indicate expansion and below 50 signal contraction. July's capacity reading of 28.4 represents the second-fastest contraction in the index's 10-year history, meaning supply chain professionals are reporting severely constrained transportation availability. This is tied only to specific data points, with the lowest on record being 23.8 in September 2020.

Why is trucking capacity declining so sharply if demand is cooling seasonally?

Two structural factors are reducing supply: regulatory authorities are removing unsafe drivers from the market, tightening driver availability; and major carriers like Werner and Schneider are deliberately reducing fleet size to improve profitability rather than expand capacity. These carriers are optimizing asset utilization instead, keeping fewer trucks but running them harder and at higher rates. This is a strategic shift, not a temporary downturn.

What does the 3.74-day booking lead time mean for shippers?

This 11% increase from the prior year indicates shippers must reserve trucking capacity nearly 4 days before freight needs to move—a significant extension. This reflects extreme tightness and forces shippers to forecast demand more accurately and lock in rates earlier, reducing flexibility and potentially increasing demurrage or detention costs if plans change.

How are warehousing costs being affected and why?

Warehouse prices jumped to 75.5, the second-highest reading since July 2022 (post-COVID peak). This is driven by tight warehousing capacity (46.3 reading) and a possible buildup of retailer inventory ahead of potential tariff changes. Upstream companies (manufacturers/wholesalers) are facing even steeper pressure, with prices 12 points higher at the wholesale level, squeezing margin across the supply chain.

What should shippers expect for the next 12 months based on logistics manager forecasts?

Managers surveyed expect the market to remain very tight: future capacity readings of 40.4 (still below 50), utilization of 71.8, and pricing at 89.2—all signaling continued constraint and elevated rates. This suggests supply chain leaders should lock in favorable transportation contracts now, build inventory strategically, and invest in demand planning to navigate sustained high logistics costs.

The signal

S. trucking market, with transportation capacity contracting at the second-fastest rate in the Logistics Managers' Index's 10-year history. 4 signals severe constraint, driven by regulatory removal of unsafe drivers and carrier decisions to optimize existing fleets rather than add equipment. 9, indicating persistent demand pressure despite cooler seasonal conditions.

Major carriers like Werner Enterprises and Schneider National are capitalizing on the tight market through strategic fleet restructuring and selective account management. Werner's one-way fleet shrank 34% while revenue per truck jumped 28% year-over-year, exemplifying how carriers are prioritizing profitability over volume in a capacity-constrained environment. 74 days, up 11% annually, reflecting shippers' urgency to secure limited capacity ahead of peak season. For supply chain professionals, this signals sustained elevated logistics costs through year-end.

Warehouse prices hit their second-highest level since the post-COVID inventory surge, and downstream retailers are rapidly depleting inventory buffers—possibly due to pre-tariff import surges. The combination of tight trucking capacity, elevated warehousing costs, and inventory volatility creates a compounding cost pressure that demands immediate attention to transportation contracts, warehouse negotiations, and demand planning strategies.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

strategic

What if trucking capacity remains constrained through Q4?

Simulate sustained transportation capacity constraint at current July 2026 levels (LMI capacity: 28.4) through Q4 2026, with trucking rates maintaining 89.2+ pricing index through peak season. Model impact on fulfillment speed, inventory positioning requirements, and mode shifts (e.g., LTL vs. TL, regional vs. long-haul). Assess cost implications of extended booking lead times (3.74 days) on demand planning accuracy.

Simulation Suggestion

immediate

What if rate increases from contract renewals accelerate beyond 10-13% YoY?

Simulate transportation rate escalation above the 10-13% YoY increases forecasted by Werner and Schneider. Model cumulative impact on landed costs, margin compression, and need to adjust pricing or reduce freight spend through consolidation, mode shifts, or demand redistribution. Test sensitivity of procurement to spot market rate volatility given current June 2021 parity signals.

What if warehouse capacity tightens further amid tariff-driven inventory swings?

Simulate warehouse capacity contraction from 46.3 to 40 (below 50), with prices accelerating from 75.5 to 82+. Assume upstream inventory volatility driven by tariff uncertainty, with downstream retail inventory swings (currently at 46.3). Model impact on storage costs, dwell times, inventory buffer strategies, and whether to pull inventory forward or delay imports.
