When trade flows converge through fewer ports, resilience declines not from lack of volume, but from the absence of alternatives. The Maritime Connectivity Vulnerability Index maps where concentration creates exposure—not failure, but vulnerability.
It begins with a paradox: the more open a nation is to trade, the more fragile it can become—if that openness is built on sand. In 1600, the Dutch Republic dominated global shipping, yet its colonies in the East Indies collapsed under blockade because they funneled all trade through Batavia, a single port-city. Three centuries later, during the 1973 oil crisis, Japan—despite its industrial might—faced economic paralysis not because of low connectivity, but because its supply chains depended on just two maritime corridors from the Persian Gulf. The Maritime Connectivity Vulnerability Index finally gives us a lens to see this recurring flaw: resilience is not measured by how many ships visit your ports, but by how many routes survive when one burns. From the fall of Carthage, strangled by Roman control of Sicilian straits, to the 2020 ventilator shortages in Barbados during COVID-19, the lesson echoes: he who controls the chokepoint controls the fate of the connected. And yet, we keep building economies on the assumption that the sea will always be open, the canals unblocked, the ports unstruck. The MCVI is not just an index—it is a warning written in the language of data, echoing the silent collapses of empires that optimized for speed, not survival.[^1][^2][^3]
