The Forty Miles That Run the World
The Strait of Hormuz is 21 miles wide at its narrowest. Twenty percent of the world's oil passes through it every day. The Taiwan Strait is 110 miles wide — a gap whose closure would collapse the global semiconductor industry within months. The GIUK Gap is where Russian submarines disappear into the Atlantic. The Cape of Good Hope is irrelevant, until it isn't, and then suddenly 15,000 container ships are adding two weeks to their journeys. Geography has never stopped mattering. It doesn't matter most of the time; it matters catastrophically some of the time. This track maps the physical pinch-points where every assumption about global trade, energy security, and naval power gets tested against the reality of water and land.
Memorise these eight places. When one of them makes the news — and one of them will — you’ll already understand why it matters and what happens next.

Chokepoints 15 minStrait of HormuzOne-fifth of global oil—$1.2 billion per day—transits a 39-km gap where Iran's coastal missiles can hold the world economy at ransom.
-
Chokepoints 19 minStrait of MalaccaA ship transits every five minutes through the 2.7-km bottleneck near Singapore carrying one-third of global trade. Closure would cripple East Asia.
-
Chokepoints 18 minBab el-MandebHouthi attacks proved this 26-km gap between Yemen and Djibouti can reroute global shipping—disrupting 10% of seaborne trade overnight.
-
Chokepoints 19 minSuez CanalEgypt's 193-km shortcut carries 12-15% of global trade. When blockages or wars shut it—as history repeatedly shows—the world economy convulses.
-
Chokepoints 18 minBosphorus StraitAt 700 meters wide, this Istanbul waterway decides if Russia's Black Sea fleet reaches open ocean or stays trapped—giving Turkey outsized leverage.
-
Chokepoints 13 minTaiwan Strait90% of advanced semiconductors are made on one side of this 130-km passage. A Chinese assault here would trigger the gravest global crisis since 1945.
-
Chokepoints 13 minGIUK GapThe Greenland-Iceland-UK Gap is the oceanic gateway between the Arctic and the open Atlantic — the passage through which Russian submarines must transit to threaten Western shipping lanes. During the Cold War it was NATO's most critical anti-submarine warfare battleground; today it is again.

Chokepoints 12 minCape of Good HopeThe Cape of Good Hope has connected the Atlantic and Indian Oceans for five centuries of maritime trade. Written off after the Suez Canal opened, the Cape Route has repeatedly reasserted its strategic necessity whenever the shorter path north is blocked or unsafe.
