September 2026 Transport Intel Report: Navigating Capacity, Congestion and Continued Disruption

Diverging Trade Lanes Shape the Global Freight Outlook

This month, no two trade lanes are telling the same story. Capacity, demand, and rates are moving differently across markets while congestion and geopolitical developments continue to affect transportation planning in certain regions.

PSA BDP's September 2026 Air and Ocean Intel Reports examine the latest developments across global freight markets, highlighting the conditions and emerging risks shippers should be watching as they plan for the months ahead.

In our September 2026 Air and Ocean Intel Reports, our transportation teams break down the latest developments across key markets and what they could mean for the weeks ahead.

Air freight: Capacity remains uneven across global markets

The balance between air freight demand and capacity looks very different depending on the market.

While conditions vary significantly by region and trade lane, capacity remains constrained across several important corridors. Asia-Pacific continues to experience particularly tight conditions on key outbound routes, while Middle East air networks remain affected by geopolitical uncertainty and have yet to fully return to previous operating levels.

Seasonal changes could add another layer of complexity in the months ahead. As airlines transition away from summer schedules, available cargo capacity may shift on routes that are already experiencing pressure. At the same time, fuel costs and changing cargo flows continue to influence freight rates and market conditions.

For shippers, the picture remains highly dependent on origin and destination, reinforcing the importance of monitoring conditions at the individual trade-lane level.

Ocean freight: Congestion challenges effective capacity

The ocean freight market is facing a similar challenge: headline capacity does not necessarily reflect the space effectively available to shippers.

Port congestion, carrier capacity management, blank sailings and changing vessel routings continue to influence the market. Disruption across major Asian ports has become a particularly important factor, affecting vessel schedules, reliability and the availability of effective capacity across the broader network.

Elsewhere, low water levels along the Rhine continue to create challenges for European inland transportation, while strong demand for Panama Canal transits is placing additional focus on another critical global trade route.

Concurrently, selected services are gradually returning to the Suez Canal, potentially improving transit times and vessel utilization. However, continued geopolitical uncertainty in the Red Sea and Gulf region means routing, capacity and reliability remain vulnerable to further change.

Planning for a market shaped by disruption

Across both air and ocean freight, September's market reinforces a familiar theme: global transportation conditions are increasingly defined by where and how disruption occurs, not simply by how much capacity exists.

Congestion, geopolitical developments, carrier and airline network decisions, seasonal schedules and changing trade flows can quickly alter conditions across individual corridors.

For supply chain teams, maintaining visibility into these developments can help support more informed decisions around routing, lead times, capacity planning and contingency strategies.
