The Panama Canal is set to reduce the number of ships allowed to pass through the waterway each day as worsening drought conditions, linked to the strengthening El Niño weather pattern, threaten water supplies needed to operate its locks.
From October, an average of 29.5 vessels will be permitted to transit the canal each day, down from 36 in August and 32 in September. The latest reduction represents an 18 per cent fall from August levels.
The canal depends heavily on freshwater from rivers feeding Lake Gatun, which provides the water required to operate its lock system. Each transit consumes a significant amount of freshwater as ships are raised and lowered between the Atlantic and Pacific sides of the waterway.
Falling rainfall has left authorities increasingly concerned about the level of water available for shipping as well as for local communities. Officials have said the canal’s watershed received less rainfall than expected during September.
The restrictions come as El Niño is forecast to reach its strongest point later this year. The weather phenomenon can significantly alter rainfall patterns and intensify heat and drought across parts of Central and South America.
The Panama Canal is one of the world’s most important trade routes, handling about 5 per cent of global maritime trade and roughly 40 per cent of US container traffic. Its importance means restrictions can quickly affect shipping schedules, freight costs and supply chains far beyond Panama.
The latest measures are already creating pressure on shipping companies. Waiting times for vessels seeking to enter the canal have stretched to around 10 days, with some operators paying substantial sums through the canal’s auction system to secure priority passage.
One container ship reportedly paid about $4 million to move ahead of the queue, highlighting the financial consequences of congestion at the strategic waterway.
The situation has revived memories of the severe drought of 2023, when authorities were forced to reduce daily transits from 38 to just 22 vessels. The restrictions created a major backlog and pushed shipping companies to consider longer and more expensive alternative routes.
The latest disruption comes at a particularly difficult time for global shipping. Other major maritime routes are already facing disruption from geopolitical tensions, increasing the pressure on companies trying to move goods between Asia, Europe and North America.
For businesses dependent on the canal, fewer available transit slots could mean higher transportation costs, longer delivery times and greater uncertainty across international supply chains.
The impact could extend to consumers if shipping companies pass additional costs on through higher freight rates. Companies importing manufactured goods, energy products and raw materials could also face increased logistics expenses.
The situation illustrates the growing economic consequences of extreme weather. A waterway built to shorten global shipping routes is increasingly being affected by the availability of freshwater, turning climate conditions into a direct factor in international trade.
Panama’s authorities are expected to continue monitoring Lake Gatun and the wider watershed as they assess whether further restrictions will be necessary.
If drought conditions worsen as El Niño strengthens, shipping companies could face additional limits on vessel numbers or cargo capacity, potentially adding further pressure to already strained global logistics networks.
The latest restrictions therefore represent not only an environmental challenge for Panama but also a significant economic risk for international trade, with the potential to increase costs and disrupt supply chains across multiple markets
