Key Points
- The April 2026 freight market has shifted from a cyclical spike to a confirmed trend, with diesel up 45% from pre-conflict levels and no relief in sight.
- Fuel contracts designed to absorb short-duration volatility don't work when the volatility has duration. Most shippers are still operating under the wrong assumption.
- The LMI's aggregate logistics cost reading of 242.4 is the highest since April 2022 and has historically preceded supply-induced inflation. Shippers need to act on that signal now, not when it shows up in their P&L.
- The answer isn't ship less. It's ship smarter, with better data, faster math, and a clear-eyed view of your consolidation and modal options.
For a while, the question was whether this was a blip. A spike caused by a specific geopolitical event that would resolve itself in a few weeks and let everyone get back to normal.
It's not a blip. It's officially a trend.
I've been saying this in customer meetings for the past several weeks and the numbers are now making the case for me. The April Logistics Managers' Index came in at 69.9, the highest reading since March 2022. Transportation Capacity dropped to 28.4 — the second-lowest reading in the nine-and-a-half-year history of the index, just above the September 2020 pandemic nadir. Transportation Prices hit 95.0, second-highest ever. The spread between those two metrics, 66.6 points, is the widest the LMI has ever recorded.
And as of late May, nothing has changed the trajectory.
Why "Blip Thinking" Is Costing Shippers Money Right Now
Most fuel contracts are designed with averages baked in. They're built to absorb volatility that doesn't have duration. A spike that lasts two weeks? The averaging mechanism does its job and most shippers barely feel it. A spike that lasts two months, with no credible end date in sight? That's a different problem entirely, and a contract built for the first scenario gives you false confidence in the second.
National diesel averaged $4.92 per gallon in March, up from $3.72 in February. By the start of April it had crossed $5.65. That's a 45% increase from pre-conflict levels in roughly six weeks. Diesel hasn't been at these levels since mid-2022. And it isn't a shortage driving this. It's a movement and routing problem, a supply chain problem, which means it resolves when the underlying conditions resolve. Not sooner.
The question isn't whether this will eventually come down. It will. The question is whether you can afford to manage the next three to six months the same way you managed the last three to six years.
What the Aggregate Logistics Cost Signal Is Actually Telling You
The LMI introduced an aggregate logistics cost metric that combines Transportation Prices, Warehousing Prices, and Inventory Costs. In April, that number hit 242.4. For context, the last time it was at this level was April 2022, at the height of post-pandemic inflation that drove the highest U.S. consumer price increases in 40 years.
That's not a coincidence and it's not a comfortable comparison.
The LMI research team notes that supply-induced inflation is harder for the Federal Reserve to combat than demand-driven inflation because raising interest rates cannot increase supply. What we're watching play out in the transportation market right now has a direct and documented relationship with broader inflation. CPI came in at 3.3% year-over-year in March. Core inflation, which excludes food and energy, is running at 3.2% and hasn't fully absorbed the fuel shock yet because that tends to take longer to flow through.
If you're waiting for your transportation budget variances to show up before you start making decisions, you're already behind.
The Three Levers That Actually Exist
I've been in a lot of meetings recently where the unspoken question on the table is some version of "what do we do about this?" I want to be direct: there is no silver bullet. You cannot avoid the cost increase. But you can reduce your exposure, and the shippers who are navigating this best are the ones who are doing the math clearly and moving with some urgency.
The first lever is fuel strategy. Most shippers are operating under index-based fuel programs, which means they track the national average. That's fine in a stable market. In a volatile one, especially one where regional variation is significant (and right now, West Coast diesel is running well over $5.00 while parts of the Midwest are materially lower), there are non-index alternatives that let you get more granular. You won't eliminate the exposure, but you may be able to buffer it.
The second lever is consolidation. This isn't ship less. It's ship less often, in larger quantities, with better modal efficiency. When you calculate fuel cost as a percentage of the total shipment rather than per mile, the economics of holding slightly more inventory to run fuller loads start making sense. This is where the math gets nuanced because consolidation has inventory-carrying-cost implications, and those are real. The tradeoff is worth running, not assuming.
The third lever is modal optimization. Intermodal is gaining ground right now for a reason. Truckload spot rates are up 8.3% year-over-year. Intermodal rate increases are running in the low single digits. That gap is widening. For lanes in the 550-to-1,500-mile range especially, there's a meaningful cost advantage available if you have the data to identify which freight actually fits.
The Problem Isn't That the Levers Don't Work
Here's the thing I keep coming back to in these customer conversations. The strategies exist. The math is not complicated in theory. The problem is frequency and data.
Two years ago, looking at your freight cost metrics monthly was probably fine. In this market, you need to be looking weekly. And the reason most companies can't do that isn't a lack of willingness. It's that they don't have the charge-level data consolidated and normalized in a way that enables rapid analysis. If getting the answer to "why is my cost per unit weight up and how much of it is fuel?" requires a three-week data pull across multiple carrier invoices and regional systems, by the time you have the answer the conditions have changed.
AI can accelerate the math once you have the data. But you have to have the data first. That's not a technology pitch. It's just the prerequisite that keeps showing up in every conversation I'm having right now.
The shippers who are doing well in this market aren't necessarily the ones with the biggest budgets or the most sophisticated networks. They're the ones who, at some point before the market got this complicated, decided to treat their transportation data as an asset worth investing in. They can see what's happening in near real-time, run the consolidation scenarios, evaluate the modal alternatives, and make a call. The others are managing by lag.
This trend isn't breaking anytime soon. The question is whether you're set up to manage inside it, or just waiting for it to end.
