Panama Canal cuts daily transits again as drought narrows a second chokepoint

The Panama Canal Authority’s Advisory A-29-2026 caps daily transits at 34 vessels from 4 September, falling to 32 from 15 September¹. The reduction was attributed to El Nino-driven water shortages at the canal, on a route reported to handle 444 billion dollars of trade³. The step down from 34 vessels to 32 is written into the same advisory, so the tightening was scheduled rather than improvised¹.

The authority has also changed how the remaining capacity is allocated. It made temporary modifications to its transit reservation system for Neopanamax vessels, effective 30 August 2026⁴, and postponed a planned reduction in draft, keeping it at 48 feet, or 14.6 metres⁵. Scarcity is showing up in price: a shipowner reportedly paid more than 5 million US dollars for a single transit slot².

Why it matters to investors

Two of the world’s chokepoints are constrained at the same time. One analysis of oil-price risk named the Panama Canal alongside historically low water levels on the Rhine, which have affected refined-product shipments into Europe⁷. Canal pressure was also cited as weighing specifically on East Coast United States markets in commentary on freight forwarder Kuehne+Nagel⁶.

The cost shows up first in goods that cross water and have thin margins. Analysts in Trinidad and Tobago warned of higher imported food prices as a direct consequence of the transit caps¹. A slot auctioned above 5 million dollars is not a freight rate; it is a scarcity rent, and it is paid by whoever cannot wait². For freight forwarders the exposure is routing rather than fuel, with the canal named among the pressures on East Coast United States markets⁶.

What to watch

The draft decision is the one to follow. Keeping Neopanamax draft at 48 feet rather than cutting it preserves cargo capacity per ship, so a later reversal would tighten effective throughput even if the vessel count holds⁵. The reservation-system changes determine who gets the remaining slots and at what price^2,4.

The second variable is water. The current caps are tied to shortages driven by El Nino³, which means the transit number is a weather-dependent figure rather than a policy one, and the step down from 34 to 32 vessels already scheduled for mid-September is the published floor rather than a forecast¹. Refined-product routing through Europe is the parallel stress to watch, with low water on the Rhine compounding the canal constraint on the same product flows⁷. The transit reservation changes took effect at the end of August and remain temporary, which means the allocation rules can move again without a change in the vessel cap⁴.
