The Panama Canal Authority announced plans to further restrict maritime traffic through the strategic waterway due to worsening drought conditions linked to the El Niño climate phenomenon. The reduction, set to take effect in October, will limit daily transits to an average of 29.5 vessels, representing an 18% decrease from August levels. This follows an earlier reduction implemented in September, when daily passages were cut from 36 to 32 vessels.
The canal, which processes approximately 5% of global maritime trade and roughly 40% of US container shipments, depends on freshwater from rivers that feed into Lake Gatun to operate its lock system. The locks function as elevators, using water to raise and lower vessels approximately 26 meters between sea level and the lake. When water levels fall below safe thresholds for large vessels, authorities impose restrictions to maintain operational safety and preserve water resources.
The supply chain disruptions caused by the canal restrictions have created significant challenges for the shipping industry. In August, vessels faced delays of up to 10 days to enter the canal, the longest wait period since May. Some shipping companies reportedly paid approximately $4 million to bypass queues through the canal’s daily auction system. The situation has been compounded by geopolitical factors, as ongoing conflict in the Middle East has disrupted alternative shipping routes and increased logistics costs for maritime companies.
Conditions are expected to deteriorate further, as El Niño is forecast to reach peak intensity later this year and potentially become the strongest such event in four decades. The phenomenon has already generated extreme weather patterns across multiple continents, with 52 countries recording seasonal temperature records for the June-August period. The impacts have been particularly severe in Central Africa and parts of South America, where nine nations experienced their hottest June-August temperatures on record. Previous drought episodes caused even more dramatic restrictions; in 2023, daily transits were reduced to 22 vessels from an original 38, creating substantial shipping bottlenecks and forcing companies to pursue alternative maritime routes.
