Panama Canal Limits Ships as Drought Threatens Global Trade
The Panama Canal will cut daily ship transits starting in September because of low water in its reservoirs. The drought is linked to El Niño, and climate change may worsen such dry spells. The canal handles 5% of global trade, so restrictions could raise shipping costs.
The canal's lock system depends on freshwater from Gatún Lake and a second artificial reservoir, with each transit releasing water into the ocean. These same reserves also generate hydropower and supply drinking water to roughly two million people, nearly half of Panama's population, forcing authorities to balance shipping needs against essential civilian uses.
Restrictions begin September 3, cutting daily transits from 36 to 34 vessels, with a further drop to 32 by mid-September, alongside weight limits on cargo. Demand has already spiked due to conflict in the Strait of Hormuz, driving auction prices for unbooked passage from about $100,000 to roughly $380,000.
This disruption could ripple through global supply chains, potentially raising costs for goods transported by sea, which may ultimately reach consumers as higher prices. U.S. container traffic is especially exposed, given the canal carries about 40 percent of it. Shipping companies may face longer waits or lighter loads, and smaller operators could struggle with steep auction fees. The recurrence of such droughts suggests these pressures may become more frequent, affecting trade reliability and economic planning worldwide.
