Panama
Panama exhibits chokepoint vulnerability: 2023-24 drought cut Canal transits by 50%, but recovery delivered $5.7B revenue in FY2025—6% of global maritime trade through 50 miles.
Panama's economy is the Canal, and the Canal is climate-dependent—a vulnerability exposed catastrophically in 2023-2024. The worst drought in 100 years dropped Lake Gatun levels so low that daily vessel transits fell from 36-38 in July 2023 to just 18 by February 2024, with LNG transits down 66% and dry bulk down 107%. The canal handles 6% of global maritime trade and 40% of all US container traffic; disruption rippled through supply chains worldwide.
Recovery was equally dramatic. Full operations resumed by August 2024, and FY2025 revenues reached $5.7 billion (up 14.4%) with 13,404 transits (up 19.3%). The Canal Administration transferred $2.965 billion to Panama's National Treasury—surplus funds that underscore how completely this single chokepoint dominates national economics. The 50-mile passage handles roughly $270 billion in cargo annually; Panama's entire GDP is approximately $80 billion. The biological analogy is a keystone species whose presence or absence determines ecosystem function.
The solution pipeline reveals long-term adaptation. A $1.6 billion dam to feed Lake Gatun will break ground in 2027 and complete by 2032—after the next El Niño expected in 2027. A land bridge for natural gas liquids would free capacity for more LNG vessels. But as Northeastern University research warns, 'vulnerability increases with climate change.' Panama discovered in 2024 what happens when a country bets everything on controlling a metabolic chokepoint, then environmental conditions change faster than infrastructure can adapt. The Canal will remain central, but its reliability is no longer guaranteed.
