A few weeks ago I was looking at a map of the world and realized how misleading maps can be.
The oceans look enormous. The routes look endless. The ships seem free to go almost anywhere. Yet more than 70% of the world’s trade by value, and over 80% by volume, depends on a handful of surprisingly narrow places.
A canal cut through a strip of desert. A strait between two coastlines. A passage so narrow that on a map it is almost invisible.
For all our talk about globalization, supply chains, artificial intelligence, and digital economies, the physical world still matters. Perhaps more than we like to admit.
Different places and different histories. But they share one characteristic: if something goes wrong there, people thousands of kilometers away eventually notice.
This communicates something important that the map alone cannot:
- Hormuz is primarily an energy chokepoint.
- The Taiwan Strait is primarily a technology and container chokepoint.
- Malacca is the most diversified chokepoint.
- Suez + Bab-el-Mandeb form a single strategic system.
- Panama is less critical globally but highly important for specific North American and Latin American trade flows.
The Network behind the Numbers
These chokepoints are not independent. Think of them as a network.
When we think about the global economy, we tend to think about factories. Taiwanese semiconductors. German machinery. Chinese manufacturing. American technology.
But factories are only part of the story. What connects them matters just as much. One of the lessons of recent years is that a route does not need to be physically blocked to become unusable. Often the closure begins somewhere less visible: insurers raise premiums, shipping companies reroute vessels, and risk managers decide a passage is no longer worth the gamble.
The ships may still be moving and the waterway may technically remain open. Yet commerce has already started looking for another path. What struck me while researching these chokepoints is that they are not separate problems. They form a network.
Hormuz connects to Bab-el-Mandeb and Suez. Together they form a continuous energy and trade corridor. Taiwan feeds Malacca, a continuous manufacturing and semiconductor corridor. Panama increasingly serves as an overflow valve when Eurasian routes become stressed or disrupted.
Pressure in one part of the system does not disappear, it moves elsewhere. A disruption at one point does not merely reduce traffic there. It pushes pressure into the rest of the system. The result is often
- longer shipping routes,
- higher insurance premiums,
- increased fuel consumption,
- vessel shortages,
- inventory delays,
- and ultimately higher prices for consumers.
The longer I look at these maritime chokepoints, the more I find myself questioning the common assumption that globalization made geography less important.
The opposite may be true.
The world economy is not floating freely across the oceans. It is balanced on a surprisingly small number of narrow passages. Some of those passages are becoming increasingly fragile.
The next time a product arrives late, a fuel price jumps unexpectedly, or a factory slows production, the cause may not be found in a boardroom or a warehouse. It may begin in one of these narrow waterways, far beyond the horizon, where the global economy still passes single file.
