Global air cargo yields rose month-on-month in August for the first time since April, as demand climbed 4.4% year-on-year while capacity slipped 0.1%, according to IATA's latest market assessment.

Total demand, measured in cargo tonne-kilometers (CTK), increased 4.4% against August 2025, with every region reporting growth. Available cargo tonne-kilometers (ACTK) fell 0.1% over the same period — a marginal contraction, but one that tightened the demand-capacity balance enough to support pricing.

"Air cargo demand rose 4.4% year-on-year in August with all regions reporting growth even as capacity was trimmed by 0.1%," said Marie Owens Thomsen, IATA's senior vice president sustainability and chief economist.

"Strong demand and higher load factors helped airlines to recoup some of the exceptionally high fuel costs. Yields rose month-on-month for the first time since April, while global goods trade growth continues. Both are positive signs as the year-end peak season comes into view."

The yield recovery lands at a critical moment for carriers and forwarders. Four consecutive months of declining yields had squeezed revenue per kilo even as volumes held up. August's reversal, driven by fuller aircraft rather than aggressive capacity additions, gives airlines renewed leverage heading into fourth-quarter peak season contracting conversations — and shippers who delayed block space agreements may now face firmer pricing.

Trade backdrop stays supportive

The macro environment underpinning volumes remained firm. Global trade expanded 6.0% year-on-year in July, extending a run of 33 consecutive months of year-on-year growth.

Manufacturing indicators also improved in August. The Global Manufacturing Output Purchasing Managers' Index rose 0.3 points to 53.0, while the New Export Orders Index gained 1.4 points to reach 51.4 — both above the 50-point threshold that signals expansion and both pointing to continued cargo demand in the months ahead.

The one significant cost pressure sits in the fuel line. Jet fuel prices jumped 8.3% month-on-month in August and stood 79.2% higher than a year earlier. Airlines absorbed much of that increase, which explains why the yield uptick matters commercially: load factor gains, not surcharges alone, closed part of the fuel-cost gap.

North America leads, Gulf corridors lag

Regional performance diverged sharply. North American carriers posted the strongest result of any region, with demand up 6.6% year-on-year even as they cut capacity by 2.5% — a combination that virtually guarantees tighter load factors on transatlantic and transpacific freighter and belly networks.

Latin American and Caribbean carriers followed with 5.1% demand growth on a 3.3% capacity increase. Asia-Pacific airlines recorded 4.3% demand growth against a modest 1.2% capacity rise, keeping the world's largest air freight market in balance.

European carriers grew demand 4.1% while reducing capacity 3.5% — another region where shippers should expect equipment and space constraints if peak-season volumes materialize as the trade data suggests.

African airlines expanded demand 3% and capacity 14%, the region's growth remaining capacity-led rather than yield-led. Middle Eastern carriers posted the weakest performance globally: demand up just 1% against a 3.3% capacity increase, a spread that pressures loads and yields across Gulf hubs.

Trade lane data tells a similar story of divergence. Asia–North America recorded the strongest growth of the major corridors in August, followed by intra-Asia, Europe–North America and Europe–Asia. Gulf-linked lanes remained disrupted by the conflict in the Middle East, continuing to depress traffic through hubs that normally route substantial Europe–Asia and Africa–Asia flows.

What it means for the market

For forwarders, the August numbers signal that peak-season capacity on the strongest lanes — Asia–North America in particular — will be contested, and that waiting for pre-peak rate softness carries increasing risk. For carriers, the yield inflection validates capacity discipline; those that trimmed belly exposure or freighter programs, as European and North American operators did, enter the fourth quarter with stronger unit economics despite fuel costs running nearly 80% above last year's levels.

With manufacturing PMIs in expansion, export orders improving and 33 months of unbroken trade growth behind it, the demand side of the equation looks set to hold into the year-end peak — and if fuel stays elevated while capacity remains flat, the August yield recovery looks less like a one-month blip and more like the start of a firmer pricing cycle into 2027.
