Panama Canal Reduces Daily Transit Slots and Draft Limits as El Nino Drives 34 Percent Rainfall Deficit

BLUFEl Nino-driven inflows running 44 percent below normal make further Panama Canal transit cuts beyond mid-September levels likely before December 1, compressing carrier routing options into the dry season.

The Panama Canal Authority (ACP) issued a shipping advisory Thursday announcing daily transit slot cuts effective September 3: Neopanamax locks to nine slots, Panamax locks to 25, falling further to 23 by September 15 1. Reuters reported the changes cap total daily transits at 34 vessels, dropping to 32 by September 15, down from a June average of 35 2. The ACP attributed the cuts to basin hydrology, reporting rainfall from May through August 34 percent below the historical average and watershed inflows 44 percent below normal 23. The authority also postponed planned draft restrictions, delaying a 48-foot Neopanamax limit from August 26 to September 2 and a 47.5-foot limit from September 3 to October 1 124.

Analysis
Further cuts beyond the September 15 thresholds are likely before December 1, as the ACP's own advisory frames the current schedule as a floor pending El Nino's peak rather than a final settlement. Watershed inflows running 44 percent below normal give the authority little cushion heading into the dry season, and the 2023-2024 precedent shows restrictions escalating in stages once a drought cycle takes hold. Continued shortfalls would force carriers to book earlier, accept longer non-reserved wait times, or divert tonnage to Suez and Cape routes. Moderate confidence reflects the ACP's own explicit warning that El Nino severity could deepen further, though the exact pace and depth of any additional cuts remain unannounced.
