The last time US logistics costs were this high, the Federal Reserve was scrambling to contain the worst inflation in four decades. That was 2022. Now the numbers are back, and they’re bringing the same uncomfortable questions with them.
The Logistics Managers’ Index for March 2026 came in at 65.7, with the Transportation Prices sub-index rocketing to 89.4. That’s a 12.7-point jump in a single month and the highest reading since March 2022, when the Fed was about to embark on its most aggressive rate-hiking cycle in decades.
What’s driving the spike
Tensions in the Middle East, particularly around the Strait of Hormuz, have pushed fuel prices sharply higher. Declining transportation capacity has compounded the problem. When you pair shrinking supply with rising fuel costs, the math gets ugly fast.
Aggregate logistics costs in March hit 233.0, the highest since May 2022. The April LMI came in at 69.9, with May hovering around 69.5. Both readings indicate ongoing tightness in freight and warehousing, meaning this isn’t a one-month blip. It’s a trend.
The inflation echo
April 2026 saw producer prices post their largest monthly gain in four years, with higher costs across both goods and services. Producer prices are essentially a leading indicator for what consumers will eventually pay at the register.
The critical difference this time is the root cause. The 2021-2022 spike was driven by pandemic-induced disruptions: factory shutdowns, port congestion, a sudden mismatch between pent-up demand and hobbled supply chains. The current surge is rooted in geopolitical conflict, which is arguably harder to predict, harder to resolve, and potentially longer-lasting.
Consumer demand has been moderating. But when cost-push inflation is driven by supply-side shocks, moderating demand alone isn’t enough to bring prices down. Businesses still face higher input costs, and they have to pass those costs along somewhere, either to consumers or to their own margins.
What this means for investors
The sectors most directly exposed are obvious: shipping, trucking, e-commerce, and any business with thin margins that depend on predictable freight costs. If logistics costs stay elevated through mid-2026, the probability of the Fed cutting rates in the near term drops substantially.
The logistics cost spikes of late 2021 and early 2022 were among the earliest and most reliable signals that US inflation was about to peak at multi-decade highs. The current readings don’t guarantee a repeat of that magnitude, but they’re flashing the same warning lights.
