Iran Says Hormuz Stays Closed Until U.S. Attacks End: Who Actually Controls the World’s Most Important Oil Strait?

Iran says normal passage through the Strait of Hormuz will not resume while American attacks continue, while CENTCOM insists the waterway remains open. The competing claims reveal a reality between closure and freedom: ships can move, but only through militarized and politically contested routes.

Iran Says Hormuz Stays Closed Until U.S. Attacks End: Who Actually Controls the World’s Most Important Oil Strait?

Iran says the Strait of Hormuz will remain closed or heavily restricted for as long as U.S. attacks continue, rejecting American demands for normal commercial passage through the waterway.

The Islamic Revolutionary Guard Corps and other Iranian authorities have said vessels must follow Iranian-designated routes, obtain approval or accept the consequences. American officials insist that Iran does not control an international strait and that U.S. forces are keeping navigation open.

Both sides use the word “open” in ways that support their political objectives.

Commercial vessels continue to move through or near the strait. That allows Washington to argue that Iran has failed to close it. However, traffic has fallen, routes have changed and ships face military instructions, mines, missiles, drones and elevated insurance costs. That allows Tehran to argue that normal passage no longer exists without Iranian consent.

The strait can therefore be physically passable and commercially restricted at the same time.

Iran’s position is that U.S. military operations and the blockade of Iranian ports have created an armed conflict in which Tehran has the right to defend its territory and regulate security in adjacent waters. Iranian officials also say the United States violated earlier understandings intended to reopen the strait and reduce hostilities.

Washington argues that the strait is used for international navigation and cannot be converted into an Iranian toll road or political checkpoint. Secretary of State Marco Rubio has warned that accepting Iran’s claim would create a precedent for other states to control global trade chokepoints.

The legal geography is complicated. Iran and Oman border the strait. International law recognizes transit passage through straits used for international navigation, limiting the ability of coastal states to suspend movement. Iran has its own legal interpretations and has not accepted every provision in the same way as the United States.

The practical struggle is being decided by weapons rather than legal briefs.

Iran can deploy coastal missiles, drones, mines, small boats and surveillance systems. It does not need to permanently occupy every shipping lane. A small number of attacks can make shipowners hesitate and insurers raise prices.

The United States can escort vessels, strike Iranian launch sites and enforce its own routes. It can demonstrate that ships still pass, but it cannot guarantee that every transit will be safe.

This creates competing systems of authority. Iran tells vessels to follow one route. The U.S. Navy may direct them differently. A captain who obeys one side risks being treated as hostile or noncompliant by the other.

CENTCOM has also resumed a blockade against Iranian ports, redirecting commercial vessels and disabling at least one ship during the current enforcement phase. That gives Iran a powerful rhetorical argument: Washington demands freedom through Hormuz while denying freedom of access to Iranian trade.

American officials would answer that the two situations are legally different. International transit through a strait is not the same as entering an enemy port during an armed conflict. Whether that distinction persuades neutral states and shipping companies is another question.

The economic impact extends beyond Gulf exporters. Asian economies depend heavily on oil and liquefied natural gas moving through Hormuz. Higher transport and insurance costs affect fuel prices, inflation, electricity generation and manufacturing.

Oil markets have reacted to each escalation, but prices also reflect adaptation. Some states draw from storage, reroute cargo or increase production elsewhere. A partial closure can therefore persist longer than expected without creating an immediate global collapse.

Iran may see this resilience as a reason to intensify pressure. The United States may see it as evidence that its strategy is working. Both interpretations can encourage further escalation.

The Houthi blockade threat against Saudi Red Sea ports increases the danger. If Hormuz and Bab el-Mandeb are simultaneously disrupted, alternative export routes become less reliable. Saudi Arabia’s Red Sea strategy, designed to reduce dependence on Hormuz, is then exposed to pressure from Yemen.

Diplomatic proposals have reportedly focused on temporary ceasefires, agreed shipping routes and a return to earlier understandings. The problem is sequencing.

Iran wants attacks and the blockade to stop before reopening the strait. Washington wants secure navigation before reducing military pressure. Each side fears that acting first will surrender its strongest leverage.

There is no simple answer to who controls Hormuz. Iran can deny normality. The United States can force selected passage. Oman remains geographically essential. Commercial operators ultimately decide whether the risk is acceptable.

A strait is not truly open merely because one escorted tanker crosses it. It is not completely closed if hundreds of vessels continue moving under restrictions.

The most accurate description is that Hormuz has become a militarized passage governed by competing claims and conditional access.

The open question is whether either side can convert temporary coercion into a stable political arrangement—or whether the world’s most important oil route will remain “open” only under the constant threat of war.
