Preparing for Air Cargo Peak Season Amid Tariff Uncertainty

Air freight markets are entering the second half of 2025 in a state of volatility, as early signs of peak season demand clash with consumer caution and a shifting tariff landscape.

Despite President Trump suggesting that the next round of US tariffs may not take effect until August, the legal reality is firmer: the executive order issued on 9 April mandates that reciprocal tariffs will be enforced from 12:01 am EDT on 9 July, unless a further Executive Order is made. This deadline is already influencing behaviour across key trade routes and sectors, with shippers attempting to front-load freight and adjust their sourcing strategies.

As expected, June saw a seasonal lull across many air freight corridors. Rates out of Hong Kong to both Europe and North America softened slightly month-on-month, falling by low single digits, while year-on-year declines were sharper to North America, reflecting weaker consumer demand and reduced eCommerce.

The removal of de minimis exemptions combined with the imposition of tariffs on many goods, has triggered a pronounced shift in flows: air cargo volumes from China to the US have fallen around 15% since March, while rates have dropped by more than 15% over the same period. In contrast, tonnage from China to Europe is up 15% year-on-year, supported by stable rates and reallocated capacity.

Transatlantic lanes also reflect the summer dynamic. With increased belly-hold capacity from passenger flights, rates between Europe and North America dipped slightly in June. However, spot freight prices on both directions of the transatlantic remain higher than a year ago, suggesting underlying resilience.

Spot Market Dominance and Capacity Volatility
One of the most significant developments this quarter has been the dramatic shift toward the spot market on Asia Pacific–US lanes. By June, more than 70% of general cargo bookings on these routes were made on spot terms, up from around 50% in the same period last year. This trend reflects carrier uncertainty, volatile demand, and diverging expectations around tariff timing and impact.

For comparison, spot market activity on Asia-Europe lanes has remained relatively stable, with roughly 47% of cargo moving under short-term rates. The growing disparity between contract and spot pricing points to the challenges of forecasting capacity needs in politically sensitive markets.

Peak Season Prospects: Uncertainty Over Tradition
Traditionally, air freight demand accelerates from mid-August as retailers ramp up inventory for back-to-school, autumn sales, and the holiday period. However, the current market is anything but traditional. Consumer confidence remains fragile due to rising living costs and trade friction, with the largest shippers increasingly hesitant to commit to long-term air freight contracts.

Global air cargo volumes rose by just 1% year-on-year in June, with capacity growth outpacing demand for the first time in over 18 months. This imbalance is likely to pressure rates across many lanes, even as jet fuel prices spike and geopolitical risks persist.

While some Southeast Asia–US routes saw modest rate gains in June, buoyed by pre-tariff demand and capacity rebalancing, overall expectations for Q3 remain muted. Analysts warn that weaker consumer spending and ongoing tariff complications could limit any meaningful peak season surge, especially on transpacific routes.

Outlook 
Despite the structural pressures, there are opportunities for shippers in the current environment. Short-term rates are more flexible, capacity is more available than in past peak seasons, and carriers are actively repositioning services to match evolving demand patterns.

The real wildcard remains US trade policy. Without a new executive order, 9 July marks the start of a new tariff chapter that will ripple across global supply chains, just as the air freight industry typically gears up for its busiest season.

Now is the time to plan ahead.
With more flexible short-term rates, improved capacity availability, and carriers adapting to demand shifts, shippers have a unique window to secure cost-effective and reliable air freight solutions before peak season pressure builds.
