How the World Depends on the Strait of Hormuz for Energy

The Strait of Hormuz remains one of the most critical chokepoints in the global energy system, and the dependence rates shown here reveal just how unevenly the world relies on this narrow waterway. While only 2% of U.S. energy imports depend on Hormuz, the picture is dramatically different across Asia and parts of Europe.

Japan sits at the top with a striking 72% dependence, followed closely by South Korea at 65%, and both China and India at 50%. These numbers underscore how deeply Asian economies rely on uninterrupted flows of crude oil and LNG from the Persian Gulf. Europe, by contrast, shows a more moderate 18% dependence, reflecting diversified supply lines and post‑Ukraine shifts in sourcing.

Its inconceivable the White House would not have even thought about the condquences of a closed strait which had never been technically closed until now.  To see their reactions to this only underlines an incompetence regarding military operations and an absence of developing a plan of action for the closure. 

This imbalance explains why disruptions in the Strait—whether from conflict, insurance withdrawal, or shipping risk—send shockwaves through Asian energy markets first and hardest. It also highlights why regional powers invest heavily in strategic reserves, naval security, and long‑term diversification strategies.

In short, the Strait of Hormuz is not just a geographic bottleneck—it is a global economic pressure point, and its closure or instability affects nations very differently depending on how much of their energy lifeline flows through it.
