May 21st, 2026 – An unexpected rise in container spot rates from Asia to the United States, combined with the launch of a new seasonal service next month, points to the early stages of a potential peak shipping season across the trans-Pacific trade lane.
The true strength of this peak season remains uncertain. Blank sailings, fuel-related surcharges, and the transition to new annual service contracts are all contributing to upward pressure on both spot and freight-all-kind (FAK) rates. Despite these factors, several industry leaders believe market momentum is building. Hapag-Lloyd recently noted that current trans-Pacific demand remains strong and expressed optimism about the upcoming peak season during the company’s first-quarter earnings discussion on May 13th.
Ocean carriers’ general rate increase (GRI) implemented on May 15th appears to have gained traction, pushing container rates to their highest levels of the year according to multiple freight indices. The Shanghai Containerized Freight Index showed that shipping a forty-foot equivalent unit (FEU) from North Asia to the U.S. West Coast surpassed $3,000 this week, although rates were only slightly higher than the same period last year.
Forecasts from the Global Port Tracker indicate that U.S. import volumes will post modest year-over-year gains this month. However, those comparisons are somewhat misleading because import activity collapsed during the same period in 2025 after widespread U.S. tariff implementation. In another sign of expected demand growth, Maersk plans to launch a seasonal trans-Pacific extra loader service on June 8th connecting Cai Mep in Vietnam and Busan, South Korea, to Long Beach.
The outlook later in the summer appears weaker. Global Port Tracker, produced by Hackett Associates for the National Retail Federation, forecasts import volumes will decline nearly 8% in July and 5% in August compared to last year.
Part of the recent increase in trans-Pacific spot rates stems from fuel-linked surcharges that add hundreds of dollars per container, along with tighter capacity management tied to the rollout of annual service contracts that largely began May 1st. Industry leaders estimated that available capacity on Asia-to-US West Coast services dropped between 17% and 20% from mid-April through early May.
Some cargo owners also appear to have accelerated shipments ahead of higher contract pricing taking effect, creating a short-term surge in demand.
According to eeSea data, container lines are reducing blank sailings and gradually adding more tonnage as the peak season approaches. Nevertheless, blank sailings continue to influence the market as demand increases.
Industry experts claimed current demand remains very strong and that the industry is preparing for sustained volume pressure rather than a temporary spike, noting that several carrier actions suggest expectations for continued strong booking levels through early summer.
Experts also expect the coming weeks to remain active on the eastbound trans-Pacific route as carriers maintain stricter discipline over capacity management, a strategy that previously helped shipping lines secure record pandemic-era profits by limiting available space.
Ocean carriers are also facing mounting operational challenges. Elevated bunker fuel costs tied to ongoing geopolitical conflicts, combined with a disappointing service contract season, have left carriers unwilling to tolerate underperforming services. Earlier this month, Maersk and Evergreen reported lower first-quarter profits, while Hapag-Lloyd described its quarterly performance as unsatisfactory.
Hapag-Lloyd also acknowledged that service contract rates, excluding higher fuel expenses, were slightly lower than the previous year. Industry sources indicate that annual contracts for mid-sized importers in the 2026–2027 shipping season settled at levels roughly equal to or slightly below last year’s agreements.
Shipping lines remain highly focused on balancing rising operating costs with uncertain demand. Maersk warned investors on May 7th that inadequate capacity management could quickly erode short-term market pricing and create difficult conditions during the second half of the year.
Since the outbreak of war-driven fuel price increases, carriers have adopted a far more cautious approach to profitability and risk management. Industry analysts noted that shipping lines are now far more likely to remove capacity quickly in order to avoid operating losses.
