Panama Canal Authority to Cut Daily Transits as El Niño Drought Bites

21 August 2026

From 3 September, the Panama Canal Authority will reduce daily vessel transits from 36 to 34, falling further to 32 from 15 September, as a severe El Niño-driven drought depletes the freshwater lakes that feed the canal’s locks. The move reverses a period of relative ease earlier this year and lands at a moment when traffic through the waterway has already been elevated, boosted by US Gulf energy exports rerouted through the canal following disruption to the Strait of Hormuz.

The numbers underline why this matters well beyond Panama. The canal carries around five per cent of global maritime trade and some 40 per cent of US container traffic, with no viable substitute on the US East Coast to Asia corridor, only a costly detour of roughly 8,000 nautical miles around Cape Horn. Vessel operators are already paying a premium to avoid delay: one auction slot changed hands for close to 4 million US dollars in early August, a figure surpassed days later by a 4.6 million dollar bid.

For trading and logistics businesses, this is now a familiar pattern rather than an isolated shock. The 2023 to 2024 drought cut canal traffic by roughly a third and rippled through global supply chains for months. This second major restriction inside three years suggests freshwater scarcity, not lock capacity, has become the canal’s binding constraint, a structural risk rather than a seasonal one.

At Gapuma, where our business depends on the reliable movement of commodities and speciality chemicals across borders, developments like this reinforce the value of diversified sourcing, flexible logistics planning and close attention to the routes our supply chains depend upon.
