According to FreightWaves, the Panama Canal Authority will cut the maximum draft for cargo vessels from 49.5 feet to 47.5 feet through a series of reductions that runs into early September, forcing neo-panamax ships to carry less cargo and threatening volumes that move through East Coast ports. The move comes as drought conditions tighten water levels in Gatun Lake, the reservoir that feeds the locks of the Panama Canal, and while low water on Europe's Rhine River is squeezing inland barge operations.
Draft Reductions at the Panama Canal
FreightWaves reported that the reductions are the fourth and fifth draft adjustments this year, and they come as forecasters brace for the effects of El Niño, the climate phenomenon that brought similar dry conditions to the region in 2023. During the 2023–24 El Niño, vessel traffic was sharply curtailed, resulting in a capacity-driven bottleneck.
Under the new schedule, the maximum authorized draft for vessels transiting the Canal's neopanamax locks will be 48 feet effective August 26, 2026, and 47.5 feet by September 3. The Panama Canal Authority said the measure is based on current water levels and projected conditions for the upcoming weeks in Gatun Lake, and is part of its ongoing water management and operational strategy aimed at ensuring the long-term sustainability of its operations. The authority said it will not reduce the number of daily vessel transits.
A neo-panamax ship hauls 13,000–14,000 twenty-foot equivalent units (TEUs) and typically requires water 50 feet deep for full capacity operations, FreightWaves noted. The lower levels will force liners to carry less cargo per vessel, impacting volumes headed for East Coast ports.
| Effective date | Maximum draft (feet) | Change from 49.5 ft |
|---|---|---|
| Current | 49.5 | — |
| August 26, 2026 | 48 | -1.5 ft |
| September 3, 2026 | 47.5 | -2.0 ft |
Carriers Add Canal-Related Surcharges
FreightWaves reported that carriers have already imposed Canal-related charges. Mediterranean Shipping Co. (MSC) assessed a $100 per TEU charge on Asia-U.S. East and Gulf Coast cargo, and CMA CGM charges have been reported at up to $320 per TEU for this trade.
| Carrier | Charge | Trade lane |
|---|---|---|
| MSC | $100 per TEU | Asia-U.S. East and Gulf Coast |
| CMA CGM | up to $320 per TEU | Asia-U.S. East and Gulf Coast |
West Coast and Canada Routings Gain Ground
In a competitive benefit for West Coast–intermodal routings, some discretionary Asia cargo bound for inland markets may shift through Los Angeles-Long Beach, Oakland, and Seattle-Tacoma on the U.S. West Coast, or Prince Rupert and Vancouver in Canada, and then move by rail, according to FreightWaves. That trades a longer and possibly costlier domestic rail leg for more dependable vessel payload availability through the all-water Panama route.
Rhine River Drought Adds European Pressure
FreightWaves also reported that drought is affecting traffic on the Rhine River, which connects the ports of Rotterdam and Antwerp-Bruges with major industrial hubs across the Netherlands, Germany, Switzerland and Central Europe. DHL said current low water levels are creating significant challenges for inland transportation. Reduced barge capacity is leading to longer transit times, rising transportation costs, and increasing pressure on alternative rail and road networks.
What Shippers and Operators Should Do
For shippers moving Asian cargo to the U.S. East and Gulf Coasts, the draft cuts mean higher unit costs through Canal-related surcharges from MSC and CMA CGM, plus the risk of capacity reductions as vessels load fewer boxes. FreightWaves noted the lower levels will force liners to carry less cargo per vessel, impacting volumes headed for East Coast ports. Operators should evaluate West Coast and Canadian intermodal alternatives now, since those routings offer more dependable vessel payload availability. In Europe, shippers using Rhine barge services should model longer transit times and rising costs, with pressure shifting to rail and road networks.
