Is the Strait of Hormuz International Waters

SEPARATE CLAIM FROM REALITY

Background and Legal Framework

The Strait of Hormuz lies between Iran and the United Arab Emirates, measuring about 21 miles at its narrowest point. Its strategic importance stems from the fact that it is the sole exit for approximately 20% of the world’s oil exports. Legally, the United Nations Convention on the Law of the Sea (UNCLOS) defines international waters as those beyond 12 nautical miles from a coastal state’s baseline. The strait’s width—about 28 nautical miles at its widest—places it partially within the territorial seas of both Iran and the UAE, yet the waterway itself remains a corridor of international passage.

While the strait is not fully outside national jurisdictions, UNCLOS guarantees the right of innocent passage for all vessels, including warships. This means that no state can unilaterally close the strait or impose arbitrary restrictions, although they can enforce security measures consistent with international law. The nuanced legal status—partly territorial, partly international—often fuels misunderstandings about sovereignty and freedom of navigation.

MYTHS WORTH RECHECKING

Common Misconceptions About the Strait’s Status

Three widespread oversimplifications circulate online. Below we debunk each one and explain the real legal picture.

01

It’s fully international waters

The strait’s narrowness means that both bordering countries control segments of the surrounding waters. While the core channel is open to international traffic, the adjacent areas fall under each country’s territorial claims.

02

It’s a national waterway of Iran

Only the portion within Iran’s 12‑mile territorial sea is subject to Iranian law. The UAE’s adjacent territorial waters also extend into the strait, and the core channel remains an international transit route.

03

Vessels can ignore all local regulations

In practice, ships must comply with navigation rules, port entry procedures, and security protocols of both bordering states. Failure to do so can lead to detention or fines, even though the passage itself is internationally recognized.

VERIFY THE PICTURE

How to Verify a Claim About International Waters

Before you accept an assertion about the Strait of Hormuz—or any maritime boundary—apply a simple four‑step check. This method helps separate fact from fiction and ensures you’re basing decisions on reliable sources.

  1. Step 1: Identify the Legal SourceLook for references to UNCLOS, national maritime laws, or United Nations resolutions. Legitimate claims cite these documents rather than anonymous blogs.
  2. Step 2: Check Geographic AccuracyConfirm the coordinates and width of the waterway. A true international passage must exceed 12 nautical miles from the nearest baseline, which is not the case for the entire strait.
  3. Step 3: Examine Historical ContextReview historical treaties or disputes, such as Iran–UAE agreements on navigation rights, to understand how the status evolved over time.
  4. Step 4: Consult Multiple Reputable SourcesCross‑reference academic journals, government releases, and international maritime organizations. Consistency across independent authorities signals credibility.
