Panama Canal Scraps Its October Draft Cut, Handing Neopanamax Ships Back Roughly 400 TEU

The Panama Canal Authority has indefinitely postponed a planned reduction in the maximum authorized draft for vessels transiting the Neopanamax locks, canceling a drop from 14.63 meters (48.0 feet) to 14.48 meters (47.5 feet) Tropical Fresh Water that had been scheduled to take effect October 1. The announcement, published September 4, is the first pause in a string of tightening moves the Authority has made through 2026 as it manages Gatun Lake water levels through the dry season and prepares for a forecast El Niño event.

The Authority attributed the reversal to "the latest review of Gatun Lake levels and weather projections," saying the current draft "provides greater continuity for voyage planning and vessel deployment" while preserving "safe and efficient operations." It did not commit to holding the 48-foot limit through any specific date, saying instead that it will "continue evaluating water conditions and will provide advance notice of any future changes."

A year of tightening, one pause

The move breaks a pattern that has run since summer. Neopanamax draft started the year at 49.5 feet and has been cut in stages to 49, then 48.5, then 48 feet — that last reduction itself delayed once already, from an original August 26 date to September 2, according to Panama Canal Authority Advisory A-29-2026, which cited rainfall running 34% below average and watershed inflows down 44% for the hydrological year. The same advisory laid out the now-postponed September 3-to-October 1 timeline for the 47.5-foot cut, alongside daily transit-slot limits: nine Neopanamax slots per day, with only one available during the system's Booking Period 2, and a Panamax-locks limit that was tightened further, to 23 daily slots, on September 1.

None of the slot restrictions are affected by this week's announcement — only the draft limit itself. Canal Administrator Ricaurte Vásquez has flagged the coming El Niño pattern as the bigger risk, warning in remarks reported by trade press that the outlook points to "a very, very low level" of precipitation heading into 2027's dry season, which suggests this reprieve is a pause in the cycle rather than an end to it.

What half a foot is worth

Draft restrictions convert into lost cargo capacity at a rate that industry analysis puts at roughly 800 TEU per foot of draft for New Panamax-class ships operating at the top of the size range — a relationship documented during the Canal's more severe 2023 drought restrictions, when a six-foot cut from 50 feet to 44 feet stripped out about 40% of a vessel's rated capacity, or roughly 5,000 TEU. Applied to the half-foot cut the Authority just canceled, that works out to somewhere in the neighborhood of 400 TEU per transit restored to the largest ships using the locks — cargo that would otherwise have had to move by an alternate routing or wait for a lighter load.

What this means for ocean capacity planners

Three things forwarders and NVOCCs booking Asia-to-U.S. East Coast and Gulf capacity should take from this:

• Existing canal surcharges don't disappear with the postponement. CMA CGM, Hapag-Lloyd and MSC have all layered on separate per-TEU canal charges this year — $320, $130 and $100 respectively on East and Gulf Coast cargo — tied to the broader restriction regime, not to the specific 47.5-foot threshold. Don't expect those to roll back just because the October cut was shelved; carriers set them independently and "are not working from a common formula," meaning identical cargo can carry different canal costs depending on carrier.
• The reprieve is conditional, not structural. The Authority's own language — "advance notice of any future changes" — is a hedge, not a commitment. Booking desks planning Q4 and Q1 capacity around a stable 48-foot draft should build in a contingency for the 47.5-foot cut resurfacing on short notice if El Niño verifies as forecast.
• Slot scarcity, not draft, is now the tighter constraint. With Panamax daily slots down to 23 and Neopanamax Booking Period 2 access effectively down to a single confirmed slot, the marginal ship is more likely to be turned away by lack of a reservation than by draft alone — a distinction that matters for whether a shipper's mitigation strategy should be a lighter load or an earlier booking.
