Panama Canal Cuts Daily Transits as El Niño Drought Deepens
8/22/2026, 8:02:48 PM
Core Event
The Panama Canal Authority (ACP) announced that, beginning September 3 the daily transit cap will fall from 36 to 34 vessels, and on September 15 it will be reduced further to 32 vessels. The limits apply to both the Neopanamax and Panamax lock systems. The authority warned that the measures are needed to preserve water for canal operations and local consumption.
Background & Context
An unusually strong El Niño has driven Central America into a severe drought. Rainfall across the canal watershed from May to August was 34 % below the historical average, while watershed inflows were 44 % below normal. Similar conditions in 2023-2024 forced the canal to cut daily transits to as low as 22 ships and to impose strict draft limits. The current restrictions are the first reduction of daily slots since the authority pledged in May to maintain normal capacity.
Timeline
- September 3 – Transit cap set at 34 vessels per day.
- September 4 – First day the new cap is in effect.
- September 2 – Maximum Neopanamax draft lowered to 48 ft (14.63 m).
- September 15 – Transit cap lowered to 32 vessels per day.
- October 1 – Neopanamax draft further reduced to 47.5 ft (14.48 m).
- August 26 – Planned draft reduction to 48 ft postponed to September 2.
Data & Statistics
- The canal handles about 5 % of global maritime trade and roughly 40 % of U.S. container traffic.
- Average daily transits in June were 32.5; in July the average rose to about 35, still below the design capacity of ~40.
- Auction prices for non-reserved slots have surged: the average winning bid in March-April was $385,000, and a single container ship paid $4 million on August 10 to jump the line. Bloomberg later reported a record $4.6 million bid for a Neopanamax slot.
- As of August 20, 124 vessels were waiting, with 88 already holding reservations; average wait times for non-booked ships were about 8 days northbound and 7.7 days southbound.
Why It Matters / Impact
Reduced capacity forces carriers to either carry lighter loads (due to draft limits) or pay higher auction fees, both of which raise freight costs. Mediterranean Shipping Company (MSC) announced a surcharge increase effective September 12 for shipments from East Asia to the U.S. East and Gulf coasts. Higher transport costs are expected to affect a range of goods, from electronics to agricultural products and pharmaceuticals.
Official Statements & Responses
- Flexport reported that the backlog at the Pacific end was the worst in three months, attributing the congestion to both the El Niño drought and displaced traffic from the Strait of Hormuz.
On-the-Ground Reports
Ships without reservations face long queues. A container ship that paid $4 million on August 10 was reported to have 30 of its containers owned by Flexport.
Conflicting Reports & Gaps
Auction-slot prices are reported at $4 million and $4.6 million (Bloomberg via gcaptain). Both figures are attributed to different carriers, indicating a lack of a single verified price ceiling. While the ACP postponed the August 26 draft reduction, the exact timing of any further restrictions remains unspecified.
What’s Next
Draft limits will take effect on September 2 (48 ft) and October 1 (47.5 ft). The authority also announced a restructuring of its daily auction system into four cargo-type groups beginning September 3, aiming for a more equitable allocation of the reduced slots. Further operational adjustments will be announced if water conditions deteriorate.
