Escalation in the Strait of Hormuz Tests the U.S.–Iran Ceasefire

Recent Hostilities and Claims
On June 25 2026 a Singapore-flagged container ship, M/V Ever Lovely, was struck by an unidentified projectile while transiting the Strait of Hormuz along the Omani coast. The United States attributed the attack to Iran’s Islamic Revolutionary Guard Corps (IRGC) and responded with airstrikes on Iranian missile-storage sites, radar installations and drone depots. The following day a Panama-flagged tanker, MV Kiku, was hit by a one-way attack drone; U.S. Central Command (CENTCOM) again cited Iranian aggression and launched a second wave of strikes. Both sides exchanged accusations of cease-fire violations within hours of each other.
MOU Background and Shipping Arrangements
The June 17 memorandum of understanding (MOU) between President Donald Trump and Iranian President Masoud Pezeshkian halted the four-month war and required Iran to use “its best efforts” to ensure toll-free safe passage of commercial vessels for 60 days. Paragraph 5 of the MOU also called for joint discussions between Iran, Oman and other littoral states on future administration of the waterway. The agreement did not specify a direct military-to-military hotline; U.S. officials later claimed a channel had been established, a claim the IRGC rejected.
Shipping Routes and Traffic Data
Three corridors now operate in the 21-mile-wide strait: a northern route under Iranian control, a traditional central traffic separation scheme (currently unsafe due to mines), and a southern route hugging Oman’s coastline coordinated by the International Maritime Organization (IMO). Kpler data recorded 70 vessel crossings on June 24, 62 on June 25, and a peak of 125 crossings between June 15-21, roughly 53 % of pre-war daily traffic (? 120-140 vessels). The strait carries about 20 % of global oil and liquefied natural gas shipments.
Official Statements & Responses
- United States: CENTCOM described Iran’s actions as “unwarranted aggression against commercial shipping” and affirmed continued “safe passage coordination and support” for vessels. Vice President JD Vance warned that any disagreement over the MOU should be resolved by phone, adding that “violence will be met with violence.” Secretary of State Marco Rubio reiterated that no tolls or fees may be imposed on an international waterway.
- Iran: IRGC spokesman Hossein Mohebi denied any U.S.-Iran hotline and asserted Iranian sovereignty over the strait. Deputy Foreign Minister Kazem Gharibabadi warned that safe passage cannot be guaranteed without Iranian coordination. The newly created Persian Gulf Strait Authority (PGSA) stated that vessels using routes outside its framework would forfeit safe-passage guarantees and insurance coverage.
- Oman: Foreign Minister Badr Albusaidi affirmed Oman’s commitment to “toll-free safe passage” and to cooperate with Iran and the IMO on navigation management.
- IMO: Secretary-General Arsenio Domínguez paused the evacuation of stranded ships pending safety guarantees after the Ever Lovely incident.
Criticism & Opposition
Shipping-risk analysts, including Dimitris Maniatis, CEO of Marisks, described the situation as “very confusing for safely navigating those waters” and warned that the “current environment is extremely dangerous.” U.S. officials and Gulf Cooperation Council members have condemned Iran’s attempts to impose fees, labeling them a breach of international maritime law.
Conflicting Reports & Gaps
U.S. officials identified Iranian drones as the source of both attacks, while Iranian state media offered no confirmation and later issued a generic “defensive” response. Press TV reported a communication line had been set up after the Swiss talks, a claim the IRGC later called “a complete lie.” The exact status of mine clearance in the central lane and the legal standing of the three parallel routes remain unresolved.
Verbatim Quotes
- “Claims by American officials regarding the establishment of a direct line between Iran and the United States concerning the Strait of Hormuz” are completely false, Mohebi wrote on X.” — Hossein Mohebi, IRGC spokesman
- “One of the drones solidly hit the upper deck of a large and very expensive cargo carrying ship. Damage was done, but the ship was able to proceed on its way. We knocked down three other drones. Obviously, this is a foolish violation of our ceasefire agreement.” — Donald Trump, President of the United States
- “If they have disagreements about how the MoU is being applied, they can pick up the phone. But violence will be met with violence,” — JD Vance, U.S. Vice President
- “safe passage through the Strait of Hormuz cannot be guaranteed under ambiguous arrangements, parallel routes or decision-making that does not take Iran’s role as a coastal state into account.” — Kazem Gharibabadi, Deputy Foreign Minister of Iran
- “All this is very confusing for safely navigating those waters,” — Dimitris Maniatis, CEO of Marisks
Outlook
The 60-day cease-fire window expires in mid-August, and negotiators in Switzerland are slated to discuss the final status of navigation, fee structures and mine clearance. Both sides have signaled willingness to maintain the hotline-like diplomatic channel, yet recent exchanges underscore the fragility of the arrangement and the risk of further escalation.
