Executive Summary
The Panama Canal is preparing to reduce vessel transits again as strengthening El Niño drought conditions reduce the freshwater available to operate the waterway.
The Canal normally depends upon rainfall-fed reservoirs to supply the enormous volumes of freshwater required to operate its locks.
Daily vessel transits were reduced from 36 to 34 from 4 September.
A further reduction to 32 vessels per day is scheduled from 15 September.
Panama Canal officials have now warned that additional reductions may be necessary if rainfall during September, October and November fails to restore reservoir levels.
Further cuts could follow early next year.
Draft restrictions have also been tightened.
That means vessels may have to carry less cargo in order to safely transit the Canal.
The logistics significance is substantial.
Businesses may face fewer available transit slots at the same time that individual vessels are able to carry less cargo.
UK Impact
UK companies using trade routes between the Atlantic and Pacific should consider exposure involving:
- Container shipping.
- LNG.
- LPG.
- Agricultural commodities.
- Automotive products.
- Machinery.
- Chemicals.
- Asian manufacturing.
- North American trade.
The cost consequences are already becoming visible.
Competition for Canal slots has increased sharply, with some vessels paying exceptionally high auction premiums to secure priority passage.
Where a ship cannot obtain a slot, alternatives include waiting or taking a substantially longer route.
Both increase cost.
Global Impact
The Canal handles approximately 5% of global maritime trade.
Its importance is particularly elevated at present because other major maritime routes are also under pressure.
Hormuz remains severely disrupted.
That means two entirely different global chokepoints are experiencing simultaneous constraints for completely different reasons:
- Geopolitical conflict in Hormuz.
- Freshwater shortage in Panama.
This creates an important diversification problem.
A business may believe it has reduced geopolitical risk by changing route only to encounter climate-related congestion elsewhere.
Lower draft limits create a second issue.
Ships may need to:
- Reduce cargo.
- Offload cargo.
- Use additional vessels.
- Change routes.
Each option increases cost or complexity.
Our View
Businesses using Panama Canal routes should begin contingency planning before further reductions are imposed.
Companies should ask:
- Does the voyage depend upon Panama?
- Has the carrier secured a transit slot?
- Is the slot guaranteed?
- What waiting time is currently expected?
- Does the vessel meet draft restrictions?
- Will cargo need to be reduced?
- Could cargo move by another vessel?
- Could the shipment use an alternative route?
- What would Cape routing add to voyage time?
- Could US rail provide a land bridge?
- Who pays canal-auction premiums?
- Can carriers pass those costs through?
- Are delivery dates flexible?
- Is additional inventory required?
- Does marine insurance remain adequate for longer voyages?
- Could multiple chokepoints affect the same supply chain simultaneously?
The key risk is no longer simply drought at the Panama Canal.
It is drought affecting a critical maritime alternative at precisely the moment global shipping already has fewer reliable alternatives available.
