As to the Straits on who relies on it:
Top 20 in order
"Top 20 Countries Reliant on Imports via the Strait of Hormuz
Ranked by share of national energy imports or total daily volume.
Pakistan: Extremely high reliance; roughly 81% of total energy imports (oil and LNG) transit the strait.
Japan: Imports approximately 70–90% of its total oil through the strait.
South Korea: Relies on the strait for ~68–75% of its crude oil imports.

India: The second-largest buyer by volume; imports ~2.1 million barrels per day (~50% of its oil imports).
Thailand: Sources approximately 56% of its energy imports through the Persian Gulf.
Bangladesh: Highly vulnerable; relies on the strait for nearly two-thirds of its total LNG supplies.
Taiwan: Relies on the route for roughly 40% of its energy imports.
Maldives: Imports 42% of its energy through the strait.
Singapore: Regional oil hub; roughly 27–40% of its oil imports transit the waterway.

The U.S. technically falls in at drum roll…… 23. 😱
But not for oil.
"As of early 2025/2026, the U.S. receives only about 2.5% to 7% of its total crude oil imports through the Strait of Hormuz. This accounts for approximately 400,000 to 500,000 barrels per day.

An amount we can easily make up elsewhere.
