- —Why now With El Niño back, the canal trimmed daily slots in September after rainfall in its watershed fell short.
- —What happened On Monday, 5 October, the canal authority said it will auction 558 long-term slots for January to April 2027.
- —The numbers The older Panamax locks join for the first time with 288 slots; the larger Neopanamax locks offer 270.

Panama will auction 558 canal slots for the 2027 dry season in advance, adding its older locks for the first time.
Panama Canal slots for the 2027 dry season will go to auction in November, the canal authority said on Monday, 5 October. For the first time, the older Panamax locks will join the scheme, alongside the larger Neopanamax locks opened in 2016.
The United States is the canal’s biggest user, so its dry-season capacity matters for US shipping costs. Booking early lets carriers avoid the kind of queues that built up during the 2023 drought.
How the Panama Canal Slots Auction Works
The scheme, called the Long-Term Slot Allocation programme or LoTSA, sells a package of transits in a single deal. It targets lines with fixed schedules and customers who struggle to win slots through normal booking, the Panama daily La Prensa reported.
For the Neopanamax locks, the Panama Canal Authority offers 36 packages with 270 slots, 165 northbound and 105 southbound. That auction takes place on Tuesday, 17 November.
The Panamax pilot offers 51 packages with 288 slots, 147 northbound and 141 southbound, auctioned on Tuesday, 24 November. Each lock system averages three LoTSA slots a day between 3 January and 3 April 2027.
Winners pay an extra reservation fee that varies by vessel type and size, La Prensa reported. The first booking window opens on Wednesday, 16 December.
“LoTSA is designed to give customers greater predictability in planning their operations,” the authority said. It added that the scheme lets them secure transit space in advance during the dry season.
Why the Dry Season Matters
The locks run on fresh water from Gatun Lake, a rain-fed reservoir. Every ship that passes releases a large volume of that water into the sea.
In the 2023–24 El Niño, low water forced deep transit cuts and cargo fell about 40 percent, La Prensa reported. Some ships waited 21 days when the lake dropped to 79.6 feet in August 2023.
Rain fell short again this year. On Thursday, 20 August, the authority cut daily slots from 3 September, citing below-expected rainfall and El Niño effects.
Conditions have since eased slightly, with a 49-foot draft limit now in force at the Neopanamax locks. From Thursday, 15 October, those locks return to 10 daily transits, for 33 daily slots in all.
Demand has stayed firm. From October 2025 to June 2026, the canal reported 10,726 transits, up 5.2 percent, and transit revenue of US$4.8 billion.
Stricter Rules on Late Cancellations
The authority also tightened penalties for cancelling bookings, La Prensa reported. From 15 October, cancelling with four days’ notice or less will carry a surcharge of 250 percent of the reservation fee.
Late cancellations leave scarce slots unused. That matters more when water, not demand, sets the limit on how many ships can pass.
What It Means for You
The United States accounts for about two thirds of canal cargo, according to the authority’s route guide. Its busiest corridor links the US East Coast with Asia.
For US consumers and importers, dry-season capacity feeds into freight rates on that route. Fitch Ratings has said logistics costs could rise up to 15 percent in some scenarios, La Prensa reported.
For investors in shipping lines and gas exporters, Panama Canal slots won in November reduce the risk of costly delays next spring. Gas carriers are the second-largest user of the larger locks after container ships, La Estrella de Panamá reported.
What Is Not Known
The authority has not published reserve prices or the size of the extra fees. Nor is it known how much rain will fall before the dry season sets in around December.
Full results for fiscal year 2026, which ended on Wednesday, 30 September, have not yet been released.
What Comes Next
The authority released last year’s full-year results on 8 October 2025 and has not set a date this year. The two auctions follow on 17 and 24 November.
The auction is not a forecast of severe cuts or a shutdown. It is a booking tool that lets the canal share out limited dry-season capacity early.
Frequently Asked Questions
What is the Panama Canal’s LoTSA programme?
It is an auction of transit packages that lets shipping lines book dry-season passages months ahead. The 2027 round covers 3 January to 3 April.
What is the difference between Panamax and Neopanamax locks?
The Panamax locks are the original locks, opened in 1914. The Neopanamax locks, opened in 2016, take much larger ships.
Why does rainfall affect the Panama Canal?
Its locks use fresh water from Gatun Lake, which is fed by rain. When the lake runs low, the canal must cut draft limits or daily transits.
Does this affect prices in the United States?
Indirectly. The United States is the canal’s biggest user, so tighter dry-season capacity can raise freight costs on routes to US ports.
