The Panama Canal Authority has announced new restrictions on vessel traffic and cargo capacity as a record-strength El Niño weather pattern causes drought in the region. One large container ship recently paid a $4 million auction fee on August 10 to bypass a backlog of vessels waiting to transit the waterway. The Panama Canal, a 50-mile artificial passage connecting the Atlantic and Pacific oceans, handles approximately 5% of global maritime trade and 70% of goods moving to or from the United States.
Low water levels in Lake Gatun, which feeds the canal's lock system, have forced officials to implement conservation measures. Since May 1, rainfall in Panama City has reached only 75% of its historical average, while the canal watershed's cumulative rainfall is 34% below average. These conditions follow previous extreme droughts in 2023 and 2024 that reduced daily transits from 36 to 24 ships.
To manage the water shortage, the Panama Canal Authority will reduce the maximum vessel draft—the depth a ship sits in the water—from 50 feet to 48 feet starting in September. Daily ship transits will also be restricted to 34 per day beginning September 4, dropping further to 32 transits per day by September 15. Shipping companies, including Mediterranean Shipping Company (MSC), have responded by announcing surcharges for shipments from Southeast Asia and East Asia to the U.S. East and Gulf Coasts, effective September 12.
The scale of the disruption extends beyond the maritime route, as importers begin rerouting shipments to U.S. West Coast ports in Los Angeles and Long Beach to avoid canal delays. This shift places increased demand on domestic rail and trucking networks, which logistics company Polo 4PL reports are already experiencing tight capacity. As of August 11, at least 49 of 215 foreign-flagged voyages operating under a 90-day Jones Act waiver—issued by President Donald Trump to transport energy products between U.S. ports—have relied on the Panama Canal. Reduced efficiency at this chokepoint could lead to higher domestic energy and fuel costs if these shipments are delayed.
For the average household, these logistical shifts may manifest as higher prices for electronics, produce, and fuel starting in September. While the Panama Canal Authority is exploring long-term solutions, such as a liquefied petroleum gas pipeline and the Rio Indio reservoir project to increase water storage, these projects have not yet begun construction. In the immediate term, the El Niño pattern is expected to peak between October and December, meaning the current transit restrictions and associated surcharges will likely remain in place through the end of the year. Domestic shipments by rail and truck are expected to face ongoing bottlenecks as long as the canal backlog persists.
