Panama Canal Drought Cuts Shipping Capacity

24 August 2026

Executive Summary

Drought is again beginning to restrict one of the world’s most important shipping routes.

The Panama Canal Authority has announced reductions in daily transit capacity from September because rainfall and inflows into the canal watershed have been substantially below normal.

From 4 September, overall daily vessel crossings will begin to fall, reaching 32 per day from 15 September. Neopanamax slots will be limited to nine per day, while Panamax capacity will fall to 23 daily slots. 

Rainfall between May and August has been approximately 34% below average, while watershed inflows have been around 44% below normal. 

This matters because the Panama Canal is not simply a channel connecting two oceans.

Its lock system depends upon freshwater.

When reservoir levels fall, shipping capacity can fall with them.

UK Impact

UK companies can be affected even when their goods neither originate nor terminate in Panama.

The canal is an important route connecting:

• Asia and the US East Coast.
• South America and Europe.
• US Gulf ports and Asia.
• LNG exporters and Asian buyers.

Restrictions can therefore affect UK businesses indirectly through:

• Container availability.
• Freight pricing.
• Vessel schedules.
• LNG movements.
• Commodity deliveries.
• Inventory requirements.
• Global shipping capacity.

A delay on the other side of the world can remove vessels and containers from subsequent rotations, creating knock-on effects elsewhere.

Global Impact

The restrictions demonstrate two different drought risks for shipping.

The first is transit capacity: fewer vessels can pass through the canal each day.

The second is vessel draft: if water levels deteriorate sufficiently, ships may eventually be required to carry less cargo to sit higher in the water.

Previously planned additional draft reductions have currently been postponed, so businesses should not assume further draft restrictions are already in force. But the Panama Canal Authority continues to monitor conditions. 

Previous drought restrictions in 2023–24 demonstrated how rapidly reduced canal capacity can create vessel queues and force carriers to consider alternative routes.

Our View

Businesses using Panama-dependent trade routes should start planning for capacity constraint before queues become severe.

Companies should ask:

• Does our cargo normally transit Panama?
• Has the carrier secured a transit reservation?
• How much delay can the supply chain tolerate?
• Could cargo use another route?
• What additional transit time would rerouting create?
• Would rerouting alter marine-insurance requirements?
• Could future draft restrictions reduce cargo carried per vessel?
• Are freight rates fixed or variable?
• Is additional inventory needed before September?
• Are critical deliveries competing with peak-season freight?
• Which party bears additional canal or rerouting costs?
• Are suppliers monitoring canal restrictions themselves?

This is a particularly useful reminder that infrastructure does not have to be destroyed to become a major commercial problem.

The canal can remain fully operational while becoming too constrained to support the volume of trade built around it.
