Panama Canal lifts daily transits to 34 slots on easing drought

The Panama Canal has raised its daily transit capacity to 34 slots, its first upward move since drought-driven cuts gutted the waterway's schedule. The increase, announced in an Advisory to Shipping, adds one reservation slot for Super category vessels in the Panamax locks, taking that segment from 18 to 19 slots per day.

The arithmetic matters for anyone routing Asia–US East Coast or Americas eastbound cargo. Total capacity now stands at 24 slots in the Panamax locks and 10 in the Neo-Panamax locks — still a far cry from the canal's pre-drought peak of roughly 36-plus daily transits, but a clear signal that Gatun Lake's water balance is recovering.

The same notice raises the maximum authorised draught in the Neo-Panamax locks to 15.24 metres, or 50 feet, where it will stay until further notice. For carriers, that's the difference between sailing a fully laden neopanamax boxship and leaving boxes on the quay. For shippers, it means fewer weight penalties on cargoes moving through the bigger locks.

Why the canal loosened the tap

The Panama Canal Authority (ACP) didn't dress it up. "The adjustment takes effect immediately and reflects improved lake levels and favorable hydrological forecasts, which allow the canal to optimize water use while maintaining the sustainability of its operations," the authority said in a statement.

Translation: the rain came back, and the watershed is holding enough water to sell one more slot a day without burning through reserves. The change is effective now, no phase-in.

How shippers get their hands on the new slot

The additional slot runs through the canal's regular booking system, but the allocation schedule is staggered by transit date:

• Booking dates between 12 and 17 November 2026: the slot goes to Period 3, the auction window — expect the highest bidders to take it.
• Booking dates between 18 and 23 November 2026: it moves to Period 2, the Special Competition.
• Booking dates on or after 24 November 2026: the capacity opens during the regular Second Competition Period.

The auction-first sequencing tells you the ACP expects demand to outrun supply for early dates. Carriers and charterers wanting the fresh slot in mid-November next year will pay for the privilege.

What does this change for unbooked vessels?

Very little, and the canal said so plainly. The Transit Reservation System remains the only mechanism that guarantees a transit date. Vessels without a reservation could face significant delays — canal-speak for sitting at anchor off Balboa or Cristóbal while booked traffic passes through.

Forwarders advising clients on routings should treat the 34-slot ceiling as the operative number for planning, not the theoretical maximum the canal could handle in wet years. Every additional Panamax slot eases pressure slightly, but auction pricing will keep absorbing the urgency premium.

The direction of travel, though, is now upward. With lake levels improving, hydrological forecasts favourable and draught restrictions loosening in tandem, the canal is rebuilding capacity on a trajectory that could see further slot additions if the watershed keeps recovering.
