Rubio warns of dangerous precedent in Iranian Strait of Hormuz demands
US Secretary of State Marco Rubio told Asian leaders that Iran’s demand to control the Strait of Hormuz and charge transit tolls would threaten global trade and freedom of navigation. He argued that allowing a state to impose such control over an international waterway could encourage similar actions elsewhere.
Speaking at an ASEAN meeting in Manila, Rubio said the US remained open to diplomacy but would not accept attacks on ships or Americans. The disruption has particular consequences for Asia: in 2025, Asian markets imported about 80% of the crude oil and nearly 90% of the liquefied natural gas passing through the strait.
In short
- Rubio rejects Iranian control and tolls in the Strait of Hormuz.
- He warns this could set a global precedent.
- Asia is highly exposed to disrupted energy flows.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The US position rests on the principle that international waterways are essential to global commerce and stability. International law, particularly the UN Convention on the Law of the Sea, protects freedom of navigation through straits used for international trade. Allowing Iran to unilaterally control the Strait of Hormuz and impose tolls would undermine this foundational principle and set a dangerous precedent whereby other nations controlling major waterways—the Malacca Strait, Panama Canal, or others—might follow suit, fragmenting global commerce and harming vulnerable economies that depend on reliable passage.
The case against
Iran could reasonably contend it has legitimate sovereignty over waters in its exclusive economic zone and the right to regulate activity affecting its security. The Suez and Panama Canals both charge tolls for passage; Iran might argue it deserves compensation for maintaining security and managing risks in its waters. Facing economic sanctions and military threats, Iran has genuine security concerns about foreign naval presence nearby. From this perspective, asserting control over the strait represents a measured assertion of sovereign rights rather than arbitrary disruption, and a reasonable response to external pressures.
Explained simply
The Strait of Hormuz is a narrow sea passage between Iran and Oman, linking the Gulf to the open ocean. It is a key route for oil and gas exports from Gulf countries to buyers around the world.
Iran lies on the strait’s northern shore, while Oman and the United Arab Emirates are on its southern side. Ships from many countries use the passage, and disruption can affect energy supplies and trade, particularly in Asia, which relies heavily on fuel transported through it.
The dispute concerns who can control access to the strait and whether ships can be charged to pass. It raises broader questions about freedom of navigation and how countries might respond if control over a major international shipping route were challenged.
