The Source Market Update: April 2026

March didn’t resolve cleanly, and Q2 isn’t picking up where a recovery should.

What the data is actually showing is something harder to plan around than either a downturn or a rebound: a market where demand is holding, costs are rising, and the structure of how inventory needs to move is getting more complicated – all at the same time.

That combination doesn’t reward scale alone. It rewards the ability to flex.

Demand is Holding – And in Some Places, Outrunning Assumptions

The ISM Manufacturing PMI came in at 52.7 for March – the third straight month of expansion and, up from 52.4% in February. The subindex data tells the more interesting story:

• New orders and production both growing
• Customers’ Inventories at 40.1% -- among the lowest readings since August 2022, signaling shelves are still understocked
• Supplier Deliveries slowing for the fourth straight month – a sign that demand is beginning to strain supply chains again
• The Prices Index at 78.3% -- its highest level since June 2022, up nearly 20 points in two months

That inventory signal matters more than it gets credit for. When customers believe their own shelves are understocked, restocking decisions accelerate faster than most supply chains anticipate. We saw a version of this dynamic post-COVID. The setup isn’t identical, but the inventory psychology is similar.

On the freight side, DAT Freight & Analytics reports that early 2026 is showing the strongest truckload demand since late 2024, with dry van and temperature-control spot rates posting their largest three-month increase since spring 2020 – up 21% and 13%, respectively. The spot premium ratio has turned positive across most modes for the first time in years. Not a surge, but the floor has definitely moved.

Freight is Tightening – But Not Everywhere, and Not at the Same Time

Here’s what makes this environment operationally difficult: the market isn’t moving as a whole.

The issue isn’t capacity, it’s where capacity is tightening. The latest Cass Freight Index shows shipments still running below prior-year levels even as expenditures turn higher – volumes soft, rates firming. Logistics Viewpoints is tracking the same split: some lanes tightening, others with capacity to spare.

Worth noting: DAT points out that the current tightening is primarily supply-driven – carrier attrition and capacity exiting the market – rather than a broad demand surge. That distinction matters for planning. It means rates can firm even when volumes stay soft, and that the tightening can reverse faster than it appeared if demand softens further.

That divergence creates a planning problem worse than a clean downturn. In a downturn, you cut. In a recovery, you expand. In a split market, you need lane-level visibility and the ability to route around the spots that are binding – without stranding inventory in the ones that aren’t.

The Cost Story: It’s Not Just That Costs are Rising, It’s How

The ISM Prices Index at 78.3% was notable on its own – 17 of 18 manufacturing industries reported higher costs. But the drivers are what makes this cycle different:

• Energy volatility tied to geopolitical escalation around the Strait of Hormuz – which the World Food Programme has called the most significant supply disruption since COVID-19. In early March, the national average for on-highway diesel jumped from roughly $3.90 to $4.86 per gallon in a single week, the largest weekly increase since the federal government began tracking the data in 1994.
• Tariff uncertainty still working through cost structures following the IEEPA ruling we discussed last month.
• Cascading freight costs – energy volatility doesn’t stay contained to ocean lanes; it shows up in fuel programs, accessorials, and carrier behavior across every domestic mode.

What’s different from prior cost cycles is that there’s no synchronized demand surge absorbing the increases. Costs are rising in a market that isn’t uniformly strong enough to absorb them, which means margins compress before pricing adjustments catch up. That dynamic is showing up acutely in temperature-sensitive categories – where the penalty for cost mismanagement or service failure is higher than in ambient freight, and where refrigerated capacity is tightening faster than the broader market.

The Real Complexity: Same Inventory, Multiple Destinations

Beyond volumes and costs, the structure of fulfillment is shifting in ways that don’t show up in headline data.

The same product is increasingly expected to serve retail distribution, ecommerce fulfillment, and wholesale – simultaneously, with different operational requirements for each. This isn’t a future-state problem. It’s already showing up in live operations, in brands managing multiple channel formats against the same inventory pool.

The operational issues collide fast:

• Retail compliance and labeling
• Kitting, bundling, and packaging variation
• Direct-to-consumer and pallet shipments from the same facility
• Returns handling across channels

Flexibility isn’t a feature in this environment. It’s the baseline. Networks that can absorb this kind of channel complexity – without rebuilding operations around each new requirement – are the ones gaining ground right now.
