Trans-Pacific Freight Rates: Overcapacity Drives Declines, Rerouting Limits Further Fall

The trans-Pacific container shipping market is anticipating significant rate reductions through 2025, a trend driven primarily by a persistent oversupply of vessel capacity and evolving global trade dynamics. While geopolitical tensions and strategic tariff policies are actively reshaping traditional shipping routes, these very shifts are paradoxically offering a partial buffer against what might otherwise be steeper declines in freight rates.

  • Average spot rates for containers from Asia to the U.S. west and east coasts have plummeted by 58% and 46% respectively since June 1.
  • Industry experts attribute market disruption predominantly to global vessel overcapacity.
  • Unresolved U.S.-China trade talks continue to dampen demand on the historically profitable China-U.S. trade lane.
  • Carriers are increasingly resorting to blanked sailings and cancellations to manage market imbalance and support freight rates.
  • Extensive vessel rerouting, particularly from the Red Sea and around U.S. ports, is absorbing excess capacity, providing some market stability.

Market Downturn and Capacity Glut

Recent data clearly underscores this market downturn. According to shipping analytics firm Xeneta, average spot rates for containers traversing from Asia to the U.S. west and east coasts have plummeted by 58% and 46% respectively since June 1. Xeneta forecasts further declines in the near term. This steep drop follows a brief rate uptick in late May and early June, which was spurred by shippers capitalizing on a 90-day pause in U.S. President Donald Trump’s tariffs. However, this momentum quickly dissipated as a flood of new capacity entered the market.

Industry experts universally identify overcapacity as the primary market disruptor. Erik Devetak, Chief Technology and Data Officer at Xeneta, affirmed, “There is significant overcapacity globally, and this will continue to shape the market.” Compounding this pressure are unresolved trade discussions between the U.S. and China, despite officials agreeing to seek an extension of their 90-day tariff truce. The crucial China-U.S. trade lane, historically a highly profitable route, is experiencing dampened demand, significantly impacting carrier profitability. Niki Frank, CEO of DHL Global Forwarding Asia Pacific, observed that carriers, having rushed to add capacity on the transpacific route to chase earlier gains, are now grappling with apparent oversupply as market momentum wanes.

Carrier Strategies and Future Outlook

Consequently, carriers are resorting to various operational adjustments to manage this supply-demand imbalance. Devetak anticipates that “blanked sailings and cancellations will become a recurring theme as carriers desperately try to keep freight rates up,” a strategic measure aimed at reducing available capacity. Jarl Milford, a maritime analyst at Veson Nautical, corroborates this outlook, projecting a steady decline in rates during the latter half of the year as more vessels enter service. This situation is further exacerbated by “ongoing uncertainty, including tariff policy and slowing global demand.” Ocean Network Express (ONE), a major container shipping line, has also highlighted “recent trade uncertainties” as factors complicating their visibility for the fiscal year’s latter half.

Rerouting as a Mitigating Factor

Despite the prevailing headwinds, a critical dynamic is providing some stability to the market: the extensive rerouting of vessels. Carriers are increasingly diverting from the Red Sea due to ongoing attacks by Yemeni Houthis, opting instead for longer voyages around the Cape of Good Hope. Additionally, some are bypassing specific U.S. ports to circumvent tariff implications. These extended transit times consume more ships, effectively absorbing a portion of the global excess capacity and, according to analysts, helping to establish a floor for otherwise plummeting freight rates. This strategic adaptation, while increasing operational costs and transit times for carriers, plays a vital role in balancing the supply-demand equation within a challenging market environment.
