⚓ Chokepoints: Suez, Panama, Malacca, Hormuz

What you’ll learn

1. What Is a ChokepointDefine a maritime chokepoint and grasp why so few passages carry so much trade.A chokepoint is a narrow canal or strait that ships must use because detours are far longer, so a handful of them carry an outsized share of world trade and energy. Because there is no room to spare, a single accident like the Ever Given can halt an entire fleet.
2. The Suez CanalExplain what the Suez Canal connects and why a sea-level canal matters.Opened in 1869, the sea-level Suez Canal links the Mediterranean to the Red Sea, sparing ships the voyage around Africa and carrying a large share of global trade. A 2015 expansion added a parallel channel to ease its one-way convoy bottleneck.
3. Suez in CrisisRecount the crises that have shut or threatened the Suez Canal.Suez has been a flashpoint: the 1956 nationalisation and failed invasion, the 1967–1975 closure that trapped the 'Yellow Fleet', and the 2021 Ever Given grounding that blocked global trade for six days. Each showed how one waterway can move history and markets.
4. The Panama CanalDescribe how Panama's locks lift ships across the continental divide.The Panama Canal uses three sets of gravity-fed locks to raise ships about 26 metres to Gatun Lake and back down, joining the Atlantic and Pacific. A 2016 expansion added larger locks for Neopanamax vessels.
5. The Strait of MalaccaExplain why the Strait of Malacca is one of the world's busiest passages.Malacca is the shortest sea route between the Indian Ocean and East Asia, carrying much of the region's oil and trade past Singapore. Its narrow, crowded lanes create both congestion and the strategic worry known as the 'Malacca dilemma'.
6. The Strait of HormuzShow why the Strait of Hormuz dominates world oil shipping.Hormuz is the only sea exit from the Persian Gulf, carrying roughly a fifth of the world's oil through lanes only a few kilometres wide. With no pipeline able to replace it, any threat to close it moves global oil prices.
7. Other Key PassagesIdentify other key passages: Bab-el-Mandeb, the Bosphorus and the Cape route.Bab-el-Mandeb gates the Red Sea and thus the Suez route; the Montreux-governed Bosphorus is the Black Sea's only outlet; and the Cape of Good Hope is the long fallback when a chokepoint closes. Each shapes how goods and energy move.
8. When a Chokepoint ClosesAnalyse what happens to trade when a chokepoint is blocked.A closure forces ships onto far longer detours — around 3,000–3,500 extra nautical miles and ten days around Africa — burning more fuel and draining fleet capacity, so freight costs rise worldwide. Ports then face cargo arriving in disruptive waves.
9. Navies and SecurityUnderstand why navies guard chokepoints and how security is maintained.Great powers station fleets near strategic straits, while multinational and regional patrols counter piracy where slow-moving ships are vulnerable. Cooperation around Malacca and the Gulf of Aden shows security as a shared undertaking.
10. Chokepoints and YouConnect chokepoints to everyday prices and the future of trade.These few passages shape the cost of fuel, food and goods, so disruptions reach ordinary shelves. A warming Arctic may open the Northern Sea Route, hinting at how climate could redraw trade and relieve — or reshuffle — the world's chokepoints.
