After failed peace talks with Iran, U.S. President Donald Trump announced on April 13 that the U.S. military had begun a blockade of ships leaving Iran’s ports, further disrupting a key global oil route—the Strait of Hormuz.

The Strait of Hormuz is known as one of the world’s major “chokepoints,” or key maritime passageways that are vital to the global economy.

Across the world’s vast bodies of water, where are these chokepoints located—and why do they matter to us? Watch this video.

00:00What are the world's major shipping choke points?
00:03Choke points are narrow maritime passageways or shortcuts
00:06that are critical to global trade and energy supply.
00:10Massive volumes of oil, gas, and other goods
00:13pass through these routes every single day.
00:16But because they're so narrow, they're also vulnerable.
00:19Disrupting these routes, especially oil shipments,
00:22can trigger global price spikes and even international conflict.
00:26We've seen this play out in the 2026 Middle East tension,
00:30particularly around the Strait of Hormuz.
00:34Of over 200 straits and canals worldwide,
00:37only 10 are major choke points.
00:40Where are they located?
00:43The Strait of Hormuz serves as the only sea route
00:46for about 25% of the world's seaborne oil trade.
00:50At its narrowest, the strait is just 54 kilometers wide,
00:53but ships pass through even tighter lanes
00:56with 3.7-kilometer channels for inbound and outbound traffic
01:00separated by a buffer zone.
01:04It lies between Iran and Oman,
01:06connecting the Persian Gulf to the Arabian Sea.
01:08Around 20 to 21 million barrels of oil pass through here daily,
01:12or about 30% of global trade,
01:15making it vital for countries like the Philippines,
01:17which relies on the Middle East for 96.8% of its crude oil.
01:22In early March 2026,
01:25Iran effectively closed the Strait of Hormuz
01:27following U.S. and Israeli strikes,
01:30followed by negotiations to reopen the strait
01:33and restore global shipping.
01:37Bab el-Mandeb is essential for trade between Asia and Europe.
01:41At its narrowest, it's just 32 kilometers wide,
01:45sitting between Yemen and Djibouti.
01:47It connects the Red Sea to the Gulf of Aden,
01:50making it the only gateway from the Indian Ocean to the Suez Canal.
01:534.2 million barrels of oil pass through this corridor.
01:58The Suez Canal is a key choke point,
02:01cutting nearly 8,900 kilometers off Asia-Europe travel
02:05by avoiding the trip around Africa.
02:08It runs through Egypt,
02:09separating the Sinai Peninsula from the rest of the country,
02:12and connects the Mediterranean Sea to the Red Sea.
02:15At its narrowest, it's only about 225 meters wide
02:19with around 4.9 million barrels of oil passing through every day.
02:24In 2021, a massive container ship operated by Evergreen Marine
02:28got stuck, blocking the canal and halting global trade for six days.
02:35Turkish Straits are made up of the Bosphorus and the Dardanelles,
02:39which form the only sea link between the Black Sea and the Mediterranean.
02:44This route connects much of Eastern Europe to global market,
02:47with 3.7 million barrels of oil passing through daily,
02:51including major exports from Russia to the Mediterranean.
02:555.4 million barrels of oil
02:58The Strait of Gibraltar is located between Spain and Morocco.
03:01It is the only natural sea link between the Atlantic Ocean and the Mediterranean,
03:06and the main western entry point for ships heading to the Suez Canal.
03:11The Mediterranean Sea spans about 3,700 kilometers
03:15and covers roughly 2.5 million square kilometers,
03:19but the Strait of Gibraltar is only about 13 kilometers wide.
03:25The Danish Straits are one of the busiest shipping routes,
03:29especially for Russian oil exports to Europe.
03:32They separate Denmark from Sweden, connecting the Baltic Sea to the North Sea.
03:38At their narrowest, they are just 3.7 kilometers wide,
03:42yet around 4.9 million barrels of oil pass through these waters every day.
03:49The Strait of Malacca remains the busiest oil transit choke point in the world,
03:54handling even higher volumes than the Strait of Hormuz.
03:5740% of global trade and 80% of China's oil imports sail in its waters.
04:03It sits between Malaysia, Singapore, and Indonesia.
04:08At its narrowest, it's just 2.8 kilometers wide.
04:1223.2 million barrels of oil pass through the Strait daily,
04:16a key route for oil moving from the Persian Gulf to major Asian economies like China, Japan, and South Korea.
04:26Cape of Good Hope is off the southwestern tip of the Cape Peninsula in South Africa.
04:31The route adds 10 days or more on average to journeys between Asia and Europe compared with the Suez route
04:37while also avoiding the Bob Elman-Debs trade.
04:41Since it is an open ocean, this route has been used by ships too large for the Suez Canal.
04:479.1 million barrels of oil pass through here.
04:53Taiwan's trade separates mainland China from Taiwan,
04:56connecting the East China Sea to the North and the South China Sea to the South.
05:01It's about 130 kilometers wide at its narrowest but handles more than 20% of global maritime trade by value
05:09each year.
05:10Nearly half of the world's container ships pass through these waters,
05:14along with cargo linked to the global semiconductor supply chain.
05:17All these routes transport not only oil but also essential food commodities such as rice, wheat, and maize,
05:25along with fertilizers including potassium chloride, ammonium nitrate, NPK, MAP, and urea.
05:32But what happens if these vital choke points are disrupted?
05:37When they're disrupted, prices rise fast.
05:41Supply chains slow down or even break, affecting everything from production to delivery.
05:46This can lead to energy shortages and in some cases, even food crisis.
05:52Shipping also becomes more expensive as vessels are forced to take longer routes.
05:57And while the impact is global, developing countries like the Philippines are often hit the hardest.
06:03Even the narrowest stretches of water can shape the global economy,
06:07which is why keeping them open and secure remains critical.
06:26We'll see you next time.
