Freight demand is growing faster than capacity.
In June 2026, global air cargo demand grew 8.5% year-on-year against capacity growth of 4.4% — while world export orders contracted for a fourth month. The gap is explained by a narrow segment of technology cargo, and it changes how exporters should read their freight costs.
On 29 July 2026, the International Air Transport Association (IATA) published its air cargo statistics for June. Global demand, measured in cargo tonne-kilometres, rose 8.5 per cent year on year. Capacity, measured in available cargo tonne-kilometres, grew 4.4 per cent. That gap lifted the industry-wide cargo load factor 1.7 percentage points to 46.9 per cent. European carriers recorded demand growth of 6.9 per cent against capacity growth of 3.7 per cent.
The same month’s manufacturing surveys point the other way. The global New Export Orders PMI stood at 49.4 in June — a fourth consecutive month below the 50 mark that separates expansion from contraction — while the Global Manufacturing Output PMI eased to 53.0. World export orders are shrinking; air cargo is growing at 8.5 per cent. The two figures together describe what the air freight market has become — and why general trade indicators have stopped being a reliable guide to freight costs.
The growth is concentrated in two regions and one product family
The June increase was not evenly distributed. According to IATA’s monthly analysis, North American carriers grew 13.1 per cent year on year and added more than 700 million cargo tonne-kilometres — almost 38 per cent of the industry-wide increase. Asia-Pacific carriers grew 7.9 per cent and contributed a further 34 per cent. Two regions produced nearly three-quarters of the additional traffic.
The corridor data shows where it came from. Asia–North America, the largest single trade lane with 23.5 per cent of industry-wide traffic in 2025, grew 14.7 per cent — its fifth consecutive positive month, “propelled by AI and semiconductor demand” in IATA’s words. Traffic within Asia rose 7.2 per cent on the same drivers. Europe–Asia advanced 7.1 per cent, its fortieth consecutive month of growth. Europe–North America was flat at 0.0 per cent, ending three months of contraction, and Europe–Middle East contracted 41.1 per cent as hub networks in the region were only partially restored.
IATA’s reading is explicit: with export orders subdued, the strength reflects urgent inventory movements of technology cargo rather than a general rise in exports, concentrated in consignments whose speed, reliability or value justifies premium transport.
The wider goods economy tells a different story
The World Trade Organization’s Goods Trade Barometer, published on 5 June 2026, shows the composition beneath the headline. The overall index stood at 101.7, slightly above trend but down from 102.3 in January. The spread between components is the more informative figure: electronic components at 105.5, lifted by investment in artificial-intelligence infrastructure, against automotive products at 99.8 and agricultural raw materials at 98.9.
The WTO’s Global Trade Outlook, published in March 2026, explains the mechanics. World merchandise trade volume grew 4.6 per cent in 2025 — but trade in AI-enabling goods rose 21.9 per cent and accounted for 42 per cent of total trade growth, while representing roughly one-sixth of global trade. For 2026 the WTO forecasts growth of 1.9 per cent, in a band from 1.4 per cent if energy prices remain elevated to 2.4 per cent if disruption eases and AI-related spending continues.
The implication for freight planning follows directly. Air cargo demand is no longer tracking the general goods economy; it is tracking one product cycle. A company shipping instruments, components or spare parts by air buys space in a market whose marginal price is set by a segment it does not compete in.
Capacity is tight and costs have not normalised
Airlines are not closing the gap. Industry capacity grew 4.4 per cent against demand of 8.5 per cent, and the imbalance is sharpest where European exporters buy: on international routes, European carriers added 1.8 per cent capacity against demand growth of 7.2 per cent, taking their international load factor to 54.0 per cent — up 2.7 percentage points and among the highest of any region.
Prices reflect it. Dollar-denominated air cargo yields fell 1.2 per cent from May — the first monthly decline after a run of increases — but remained 34.0 per cent above June 2025, a fourth consecutive month of double-digit annual gains. Fuel tells a similar story: jet fuel averaged US$129.5 per barrel in June, down US$28.5 from May as oil flows through the Persian Gulf partially recovered, yet still 45.8 per cent above its level a year earlier, with refining margins for aviation fuel unusually wide.
Two conclusions follow. Softer conditions in the wider economy will not automatically loosen this market, because the demand that sets its price does not move with general trade. And a falling oil headline is not yet a falling freight bill: the cost base beneath rates remains well above last year.
Swiss and European exposure runs through value, not volume
Eurostat makes the European stake precise. In 2024, 27.1 per cent of extra-EU exports by value left the European Union by air — against 2.8 per cent by weight. On the import side, air carried 18.3 per cent of value. Air freight is marginal in tonnes and central in value.
For Switzerland the concentration is stronger still. A University of St. Gallen study for IG Air Cargo Switzerland found that in 2019, goods worth CHF 157 billion — half of all Swiss export value, or 40 per cent excluding precious metals — left the country as air freight, while accounting for just 0.56 per cent of export tonnage. In intercontinental trade the value share reached 82 per cent. The average consignment was worth CHF 1,413 per kilo, chemical and pharmaceutical products alone made up 47 per cent of air freight export value excluding precious metals, and around 70 per cent of the freight travelled as belly cargo, in the holds of passenger aircraft. The figures have moved since; the structure has not: Swiss overseas competitiveness rests on a mode of transport invisible in tonnage statistics and dominant in value.
That structure defines the exposure. Belly capacity follows passenger schedules, not cargo demand, so supply on European routes cannot be assumed to respond quickly. And because corridors diverge — Europe–Asia growing at 7.1 per cent while the transatlantic lane is flat — the number that shapes a company’s freight costs is not global trade growth, nor even global air cargo growth, but conditions on the specific corridor it ships.
What a company can decide
Little of this is within a single firm’s control. Four things are.
- Budget freight by corridor, not by headline. IATA publishes demand, capacity and load factors monthly, by region and trade lane. A budget built on global trade growing 1.9 per cent and a budget built on Europe–Asia recording its fortieth consecutive month of growth produce different numbers.
- Separate genuine urgency from habit. With yields 34 per cent above last year, every shipment that flies by default rather than by necessity pays a premium set by other companies’ product cycles. The share of volume that could move by sea, road or rail with earlier planning is a controllable cost.
- Structure contracts for a market that can turn. The balance between committed capacity and spot exposure, and the way fuel and capacity surcharges are indexed, deserve review while the market is tight — not after it turns.
- Watch the electronics cycle even from outside it. The WTO’s electronic-components index and IATA’s corridor data are currently better leading indicators of air freight pricing than any general trade statistic.
The next readings have dates
IATA’s July figures, due at the end of August, will show whether the transatlantic lane returns to growth and whether Middle Eastern capacity — up only 2.5 per cent in June — continues to be restored; both would loosen conditions for European shippers. The WTO’s next barometer reading will show whether the gap between electronic components and the rest of goods trade widens or closes. The WTO’s own scenario band for 2026, from 1.4 to 2.4 per cent, is wide enough that freight assumptions deserve a review date rather than an annual setting.
The headline finding stands on its own: demand is growing faster than capacity. What matters for a European or Swiss exporter is why. Because the growth belongs to a narrow, fast-moving segment — a reliance IATA itself flags as an exposure — the market can tighten while a company’s own order book softens, and loosen just as suddenly. Either way, the firms best prepared are those that know which corridors, which contracts and which shipments their freight budget actually depends on.
