The Panama Canal, the primary maritime route linking the Atlantic and Pacific oceans, will once again reduce daily vessel crossings starting in September. The measure is a response to falling water levels in the artificial lakes that feed the canal's lock system, severely impacted by drought associated with El Niño. At the same time, the government of Panama declared a national state of emergency through June 2027 to deal with dry conditions and severe storms, according to reports by MetSul Meteorologia and Panamanian outlet Telemetro.
The Panama Canal Authority announced that the daily transit limit will drop from 36 to 34 vessels on September 3, and then to 32 vessels on September 15. Canal administrators have not ruled out further restrictions if rainfall in the coming weeks remains below expectations. Between May and August, rainfall across the canal's watershed reached 34% below the historical average, driven by the ongoing climate anomaly.
The water shortage exposes a dual vulnerability for the Central American nation: the same reservoir system that operates the locks supplies drinking water to roughly half of Panama's 4.2 million residents. In response to agricultural pressures, Panama's Ministry of Agricultural Development submitted a 2027 budget proposal to the National Assembly allocating dedicated funds to mitigate drought impacts on farms, reported local newspaper La Estrella de Panamá.
Auction bids surge as global shipping faces new delays
The waterway handles approximately 5% of global maritime trade and roughly 40% of all container traffic moving to and from the United States. Main users include the US, China, Japan, Chile, and South Korea. With daily transits restricted, waiting times are set to increase for ships without advance bookings. About nine out of ten vessels use the canal's reservation system, leaving a small remaining pool of daily slots sold through competitive auctions.
Auction prices for those unreserved slots have risen sharply. The average winning bid was around $135,000 before recent geopolitical conflicts in the Middle East, but reached $4 million in April when one shipping line paid the amount to secure passage. This week, Panamanian newspaper La Prensa reported that a South Korean carrier won a single crossing slot for $5.3 million, highlighting the financial burden placed on global supply chains.
The current El Niño, characterized by abnormal warming in the equatorial Pacific Ocean, is shaping up to be one of the strongest on record. Elsewhere in Central America, Honduras has placed 80% of its national territory under drought alerts. Globally, ocean surface temperatures reached an all-time record high of 21.10°C on August 22, according to data from the European Union's Copernicus Climate Change Service cited by MetSul. "The record is another clear signal of an ocean under increasing stress," stated Samantha Burgess, strategic climate lead at ECMWF.
The upcoming restrictions build upon prior draft reductions imposed on larger vessels. During the severe drought of 2023, daily transits were cut from 38 to 22, triggering weeks of vessel backups at both ocean entries. The Panama Canal Authority is monitoring rainfall through the end of the wet season before deciding whether additional water conservation steps will be needed.
