September, a key month for delivery forward of the vacation season, is normally a growth one contained in the freight enterprise and provide chain, with merchandise shifting from warehouses to shops or customers.
Not this yr.
The newest Logistics Managers’ Index, which tracks stock ranges, warehouse prices, transportation capability, and pricing, reveals the bottom studying it has ever recorded for transportation utilization within the month of September.
The robust progress normally seen attributable to shipments of vacation merchandise, “we aren’t seeing that,” stated Dale Rogers, a professor within the provide chain administration division at Arizona State College and one of many authors of the LMI.
The LMI rating is a mixture of eight key metrics within the logistics provide chain masking warehousing, transportation, and stock. Any studying above 50.0 signifies that logistics is increasing; a studying beneath 50.0 is indicative of a shrinking logistics business.
The Logistics Managers’ Index was at 57.4, down 1.9 factors from August, and at its lowest studying since March.
Rogers says the underlying knowledge corresponds to a declining charge of progress for future freight logistics orders and rising inventory, which will increase warehouse pricing. What he described as a “slight adverse freight inversion” that started in August continued in September. And he added that whereas transportation costs are nonetheless increasing, that’s “barely” the case.
“That is the bottom charge of progress we’ve got tracked for this metric since April 2024, which was the final month of the latest freight recession,” Rogers stated.
The headwinds are most clearly seen within the firms concerned within the upstream a part of the availability chain, he stated, the place uncooked supplies are sourced, acquired, and transported to manufacturing amenities. Upstream companies reported very marginal transportation value enlargement at 51.4.
“Respondents on the manufacturing and wholesale degree have been comparatively stagnant by way of new inventories as a result of so a lot of them front-loaded items early within the yr,” Rogers stated.
Primarily based on the LMI knowledge, quite a lot of the front-loaded products ahead of the tariffs are nonetheless within the warehouses. Now, frontloaded objects are racking up prices. Warehouse capability is tight, and pushed stock ranges over 54.2, resulting in greater stock prices.
Truck transportation from the warehouse to the shop or client is just not wanted, primarily based on the index transportation utilization studying, which declined to the baseline of fifty.0, “which signifies no motion,” Rogers famous.
The typical studying for transportation utilization in September during the last eight years of the LMI is 65.1, indicating a gentle charge of progress.
Transportation costs stay above water for now, Rogers stated, and typical seasonality would counsel that downstream exercise stays elevated by way of the remainder of 2025, in keeping with Rogers. However he says it’s too quickly to say whether or not this can preserve the freight market from falling again into recession, or if the newest knowledge is signaling a logistics sector downturn has already begun. The commerce conflict and periodic bursts of delivery to get forward of recent tariffs have induced atypical patterns throughout the financial system, from sharp adjustments in GDP readings to delayed dangers of inflation.
Historically, Rogers stated this index development would want to proceed for no less than three months earlier than it may well start to be thought-about as an indicator of an precise freight recession. The September outcomes mark the second month in a row of negative-leaning knowledge.
