Global trade lifelines exposed to risks: 27 key maritime chokepoints carry most trade volumes, with the Hormuz crisis sounding an alarm.

A new report from Oxford Economics reveals that global trade is heavily reliant on 27 critical maritime "chokepoints" — a severe disruption to any of these nodes could impact energy and goods transport, as well as the global economy. The report notes that nearly six months of U.S.-Iran tensions have disrupted shipping through the Strait of Hormuz, a core global energy transport route that carries roughly one-fifth of the world’s oil supply. Rising risks of attacks on commercial vessels have slowed shipping, driving up international oil prices, pushing U.S. gasoline costs above $4 per gallon, and further exacerbating inflationary pressures. Beyond the Strait of Hormuz, global trade is also heavily concentrated at key nodes including the Strait of Malacca, Taiwan Strait, Suez Canal, Strait of Gibraltar, and Panama Canal. Asia hosts the world’s densest network of trade routes: the Strait of Malacca, which connects the Indian and Pacific Oceans, is a key global energy and goods transport corridor, while the Taiwan Strait handles roughly one-quarter of global trade volumes. The report warns that geopolitical conflicts are among the biggest risks to global trade. Some nations may weaponize key shipping lanes for political leverage, while climate change is also raising shipping risks. For instance, drought and El Niño-driven water level drops at the Panama Canal have limited vessel cargo capacity and pushed up transport costs. Oxford Economics says the risk level of individual chokepoints depends on the availability of alternative routes. The Strait of Hormuz is particularly high-risk due to the lack of viable alternatives, while some routes can be bypassed, though longer travel distances increase fuel, labor, and operational costs, driving up global freight rates. As geopolitical tensions, extreme weather, and supply chain vulnerabilities rise, the global trade system’s reliance on critical shipping nodes is emerging as a new source of economic risk.
