Industry Briefs
Although the May Logistics Managers' Index slightly declined, it still maintained a high level of expansion.
The LMI index for May was 69.5, a slight decrease of 0.4% from April, but still the second fastest expansion rate in nearly four years. With inventory costs soaring, transportation prices rising rapidly, coupled with the impact of tariffs and geopolitical conflicts, inflationary pressures in the supply chain are emerging.
Key Data
The Logistics Managers' Index (LMI) for May 2026 registered 69.5, a slight decrease of 0.4% from April's 69.9, yet it remains the second highest expansion reading since March 2022 (76.2). The LMI uses 50 as the breakeven line, with readings above 50 indicating industry expansion.
Core Trends
Inventory Levels Slow Down: The May inventory level index stood at 54.8, down 1.5% month-over-month, primarily occurring in late May. The shift from strong expansion to near stagnation suggests a moderation in the pace of inventory restocking by businesses.
Warehousing Capacity Rebounds: The warehousing capacity index rose to 50.5, a 5.0% increase month-over-month, ending the previous contraction but with weak expansion momentum.
- Widespread Price Increases:
- The inventory cost index climbed to 84.1, up 9.4% month-over-month, reaching a new high since May 2022.
- The warehousing price index stood at 70.7, though down 2.0% from April, it remains in a significant expansion range.
- Transportation prices grew at the fastest pace in nearly a decade. The report's authors noted: "Transportation prices are the most volatile component of the LMI, but the current rate of change is particularly pronounced."
Industry Interpretation
Dr. Dale Rogers, the lead author of the report, pointed out that logistics indicators often reflect economic trends several months in advance. The sharp rise in transportation prices suggests that significant inflation may appear in GDP data over the next two to three months. He reiterated the LMI team's earlier view that the substantial impact of tariffs is expected to materialize in the summer of 2026, and with the叠加 effects of the Iran War, the two inflationary pressures could produce a massive shock.
Supply Chain Impact
Cost Pass-Through: Persistently high warehousing and transportation costs will push third-party logistics providers and retailers to reassess contract prices, increasing the pressure for price increases on downstream end-user goods.
Capacity Game: Warehousing capacity has barely emerged from contraction, yet prices remain high, indicating that demand has not weakened. The surge in transportation prices suggests ongoing capacity tightness, particularly on the Red Sea-Suez route and trans-Pacific routes affected by geopolitical conflicts.
Inventory Strategy: The shift in corporate inventory levels from "restocking" to "wait-and-see" may signal a cautious attitude toward demand prospects. If inflation and conflict persist in the second half of the year, the supply chain will face the risk of "high costs plus low turnover."
Future Outlook
The LMI has been operating above 65 since mid-2025, and the May data confirms the industry's high level of activity. However, the broad-based rise in price indicators casts a shadow over the second half of the year. If the Iran conflict expands or tariffs are further escalated, logistics costs could spike again in a pulsed manner, testing the resilience of global supply chains.
