Freight capacity is tightening despite mixed demand signals

Signal Radar Weekly | 25-31 May 2026

What happened this week

Freight pressure moved back to the centre of the supply chain picture this week.

Ocean rates increased. Blank sailings rose. Allocation pressure returned. Air cargo conditions also tightened.

None of those developments would be unusual in a strong demand environment.

The interesting part is that demand recovery still looks uneven.

Manufacturing activity has improved in some markets, but consumer demand remains mixed and business confidence remains fragile in others. Yet freight markets are tightening anyway.

For supply chain leaders, that matters because many planning assumptions still rest on a simple idea: if demand conditions remain uncertain, capacity should remain relatively easy to secure.

This week’s signals suggest that assumption deserves a second look.

The bigger pattern

This is not a new story.

Over the past three months, Signal Radar has repeatedly highlighted a disconnect between demand conditions and operating conditions.

Demand signals have has remained uneven. Some sectors have expanded. Others have stalled. Recovery has appeared in one region while fading in another.

At the same time, supply chains have become progressively harder to manage.

Freight networks have adapted rather than normalised. Trade friction has persisted even when policymakers have sought selective relief. Input-cost pressures have remained present despite softer growth expectations. Companies have increasingly focused on securing capacity and protecting service levels rather than assuming markets will loosen.

In short, mixed demand growth has not translated into easier execution.

This week's freight signals provide another piece of evidence supporting that broader pattern.

What changed

The clearest development was in freight.

In ocean freight, Drewry's World Container Index rose for a fourth consecutive week, with spot rates increasing 3% to $2,800 per FEU. Blank sailings across East-West trades increased to 47 over the next five weeks, while forwarders reported a return of "pay-to-play" conditions as carriers regained pricing and allocation leverage.

Taken together, those signals point towards tightening freight market conditions despite the absence of a clear demand acceleration.

Air cargo added a second freight stress point.

IATA reported global air cargo demand growth of 4.0% while available capacity fell by 0.4%. The association also highlighted disruption in Middle East cargo networks alongside higher yields.

The significance is not that air freight has suddenly become unavailable. It is that the alternative many companies rely upon when ocean markets tighten is becoming more constrained at the same time.

Outside freight, pressure continued to build across input and production systems.

The US Federal Trade Commission launched an investigation into fertiliser-price increases. Australia extended measures allowing fuel to be released from strategic reserves, while Sudan reported reduced planting activity as fuel and fertiliser costs constrained agricultural production.

Taken together, these signals suggest cost pressures are continuing to move through physical production systems rather than remaining confined to commodity markets.

Trade policy delivered both relief and friction.

EU governments advanced legislation designed to remove duties on many US goods. At the same time, EU officials discussed stronger trade-defence measures against Chinese imports, while major parcel operators warned that planned EU parcel-tax changes could create new customs and border disruption.

The result is a familiar pattern. Some trade barriers may ease, but operational complexity remains.

Technology supply chains also remained under pressure.

The US expanded restrictions on advanced Nvidia AI-chip shipments to Chinese firms operating outside China, extending the reach of existing controls. Separately, TSMC stated that energy consumption is becoming a primary design constraint for advanced AI chips.

The message is that technology supply chains are increasingly shaped by policy restrictions and infrastructure constraints, not just manufacturing capacity.

Why it matters

Higher rates are rarely welcomed, but the larger issue is shrinking optionality. It gets harder to work around supply chain disruptions and implement 'Plan B' when things become messy.

Many organisations continue to assume that uncertain demand conditions provide time. Time to commit inventory. Time to secure freight capacity. Time to make sourcing decisions.

That logic has worked reasonably well in recent years.

But if carriers continue 'managing' capacity while maintaining pricing discipline, and if alternative logistics options also become more constrained, that flexibility may disappear faster than expected.

Companies could find themselves facing higher transport costs and fewer operating choices before demand conditions become materially clearer.

The challenge is understanding whether demand uncertainty is still providing the operational breathing room many businesses assume exists.

Signal strength

Our confidence in this pattern increased again this week with multiple systemic indicators pointing in the same direction.

• Freight rates increased.
• Carrier capacity was withdrawn.
• Allocation pressure returned.
• Air cargo flexibility weakened.
• Input-cost pressure remained active.
• Trade friction persisted despite selective relief.

When separate drivers reinforce the same conclusion, the signal becomes harder to dismiss.

What to ask this week

Logistics

• If allocation tightened further in June, which lanes would be affected first?
• Where are we relying on spot-market access for critical customer flows?
• Which shipments justify earlier capacity commitments?

Procurement

• Which suppliers could move from price increases to allocation?
• Where are energy, fertiliser or weather pressures already changing supplier behaviour?
• Which sourcing decisions assume availability remains unchanged?

Planning and inventory

• Are we using weak demand growth as a substitute for capacity planning?
• Which products would require earlier positioning if transit reliability deteriorated?
• What would we prioritise if freight costs and input costs increased simultaneously?

Commercial and finance

• Which customer commitments depend on stable freight costs or lead times?
• What is the margin impact if freight markets tighten for another month?
• Where would earlier commitments reduce larger downstream costs?

What we are watching next

The key question is whether freight continues tightening without a corresponding strengthening of demand indicators.

If it does, the relationship between demand conditions and logistics availability may be changing.

That would be more significant than any individual freight-rate increase.

For much of the past decade, supply chain teams have assumed that uncertain or softer demand conditions create spare capacity and greater flexibility.

The evidence is becoming less clear. And that is why this week's signals matter.
