Part 2: The World’s Most Important Oil Chokepoints
Producing oil is only half the story. Once crude oil is extracted from the ground, it must travel thousands of miles to reach refineries and consumers around the world.
That journey relies on pipelines, tankers, and a handful of strategic maritime chokepoints. Among them, none is more important than the Strait of Hormuz.
The Strait of Hormuz: A Global Energy Bottleneck
The Strait of Hormuz sits between Iran and Oman at the entrance to the Persian Gulf. At its narrowest point, it is only about 21 miles wide, yet it carries an enormous share of global energy supply.
Roughly 20% of global petroleum trade passes through the Strait of Hormuz each day.
That equates to around 20 million barrels of oil per day moving through the strait.
Major exporters that rely on this route include:
- Saudi Arabia
- Iraq
- Kuwait
- United Arab Emirates
- Qatar
- Iran
Why the Strait Matters
The Persian Gulf contains some of the largest oil reserves on earth, but there are limited routes for exporting that oil to global markets.
Most shipments must pass through the Strait of Hormuz before reaching customers in:
- China
- India
- Japan
- South Korea
- Europe
Asian economies are especially dependent—nearly 90% of oil shipments through the strait head toward Asia.
A Geopolitical Flashpoint
Because so much oil flows through this narrow channel, disruptions can quickly ripple across the global economy.
Conflict, piracy, sanctions, or military tensions can threaten shipping and drive oil prices sharply higher. Recent geopolitical tensions in the region have repeatedly highlighted just how vulnerable this chokepoint can be.
Even when alternative pipelines exist, they can only carry a fraction of the region’s export capacity.
Other Major Oil Chokepoints
While Hormuz is the most important, several other routes are also critical:
- Strait of Malacca (between Malaysia and Indonesia)
- Suez Canal (Egypt)
- Bab el-Mandeb (Red Sea)
- Turkish Straits (Bosporus and Dardanelles)
Together, these routes form the arteries of the global oil system.
But geography isn’t the only force shaping oil markets. The financial system behind oil trading plays an equally powerful role.
That brings us to one of the most important concepts in global finance: the petrodollar.
