Iran has declared that the Strait of Hormuz will remain closed as long as the U.S.-led maritime blockade of Iranian ports continues, according to statements from Iranian officials and confirmed by multiple regional and international sources. The declaration comes amid an ongoing crisis in the strategic waterway that began in late February 2026 following joint U.S.-Israeli military strikes on Iran, which triggered retaliatory actions by Tehran and disrupted global energy shipping lanes.
The Strait of Hormuz, located between Oman and Iran, is one of the world’s most critical chokepoints for oil and liquefied natural gas transport, with approximately one-fifth of global petroleum consumption passing through it daily. Since the escalation began, Iranian authorities have issued warnings through the Islamic Revolutionary Guard Corps (IRGC) prohibiting vessel transit, while deploying naval forces, sea mines and electronic warfare systems to enforce restrictions. These measures have led to a near-total halt in commercial shipping, with vessel transits dropping from an average of 135 per day to fewer than 10 in the immediate aftermath of the strikes, according to maritime tracking data.
Iran’s foreign minister has stated that the current situation in the Strait is a direct consequence of U.S. Actions, emphasizing that Tehran will not allow freedom of navigation while its ports remain under effective blockade. The Iranian government maintains that the closure is a legitimate defensive measure in response to what it describes as an illegal and aggressive campaign by the United States and its allies to strangle its economy through sanctions and naval interdiction.
The U.S. Has maintained a sustained naval presence in the region, including aircraft carrier strike groups and guided-missile destroyers, to enforce what it describes as efforts to ensure freedom of navigation and counter Iranian aggression. However, Iranian officials argue that the U.S. Fleet’s positioning and interdiction efforts constitute a de facto blockade that violates international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS), which guarantees transit passage through international straits.
European nations have responded by expanding sanctions on Iranian entities involved in maritime security operations while simultaneously issuing statements affirming the importance of protecting commercial shipping in the Gulf. The European Union’s latest measures, announced in April 2026, target individuals and companies linked to the IRGC’s naval command and aim to pressure Iran into de-escalating, though Tehran has dismissed such actions as illegitimate interference.
Shipping industry analysts and energy market observers have warned that prolonged closure of the Strait would trigger significant increases in global oil and gas prices, disrupt supply chains for energy-dependent economies, and increase insurance premiums for vessels willing to risk transit. Alternative routes around the Cape of Excellent Hope add substantial time and cost to shipments, further straining already volatile markets.
As of mid-April 2026, diplomatic channels between Washington and Tehran remain largely stalled, with no active negotiations underway to resolve the standoff. Both sides have conditioned any de-escalation on reciprocal steps: the U.S. Demands Iran cease missile and drone attacks and halt interference with shipping, while Iran insists on the lifting of the naval blockade and removal of sanctions as prerequisites for renewed dialogue.
The United Nations Security Council has held informal consultations on the situation, but no binding resolutions have been adopted due to disagreements among permanent members. The International Maritime Organization has issued advisories urging caution for vessels considering transit, while regional actors such as Oman and the United Arab Emirates have called for restraint and offered to facilitate talks, though their mediation efforts have not yet yielded results.
