Maritime Chokepoint
What Is Maritime Chokepoint?
A maritime chokepoint is a narrow strait or canal through which a large share of world trade must pass, so any disruption there has outsized effects on global commerce. Because ships have few alternatives, these passages concentrate risk: blockages, conflict, or accidents can ripple through supply chains far beyond the region. Prominent examples include the Strait of Hormuz, between Iran and Oman, widely described as the world's most important oil transit chokepoint; the Strait of Malacca, between the Malay Peninsula and Sumatra, a major passage linking the Indian and Pacific Oceans; and the Suez and Panama Canals. Chokepoints are a central concept in trade geography and energy security.
Why It Matters
Chokepoints show how physical geography shapes the economics of trade. The Suez Canal, opened in 1869, connects the Mediterranean Sea and the Red Sea, dramatically shortening the route between Europe and Asia; the Panama Canal, opened in 1914, links the Atlantic and Pacific Oceans. When such a passage is obstructed, ships must take far longer detours, raising costs and delaying goods, effects felt in prices worldwide. High transport costs act like a trade barrier, raising the delivered price of imports much as a tariff does, so anything that lengthens a route dampens trade. Because a handful of narrow waterways carry so much of the world's oil and manufactured goods, governments treat chokepoint security as a strategic priority.
