As the Strait of Hormuz shipping disruption situation evolves and vessels reroute to avoid the uncertainty, the effects are showing up at ports across Asia in the form of longer queues, slower berth access, and rising delays. Portcast has been monitoring major ports across the region, and the data from the past few weeks shows that congestion is building, and shippers need to pay attention.

Strait of Hormuz Current Status and Its Impact on Port Congestion

The Strait of Hormuz is not fully closed, but the Hormuz shipping disruption has been significant enough to alter vessel behaviour at scale. Ships are holding, rerouting, or bunching at alternative ports while operators wait for clarity. The result is a spike in traffic at transhipment hubs and gateway ports that were not designed to absorb this kind of sudden demand shift.

Across the ports Portcast monitors, a clear pattern has emerged since late February 2026. Anchorage queues that were stable through January have surged into March. More vessels are waiting. Berth access is taking longer. And the ports feeling it most are the ones that sit at key transhipment and relay points along the affected trade lanes.

Where Strait of Hormuz Shipping Traffic Is Piling Up

This port congestion is not limited to a single country or port. It is happening at the same time across Southeast Asia and South Asia, suggesting a shared cause instead of local port problems.

As of March 13th, here is the port congestion trend based on data from our platform:
