Iran’s IRGC Warns Against New Hormuz Shipping Route Amid Fragile U.S.–Iran Deal
6/26/2026, 6:34:35 AM
Core Event: IRGC Warning and Vessel Attack Halt UN Evacuation
The Islamic Revolutionary Guard Corps (IRGC) announced that only routes “designated by the Islamic Republic of Iran” are authorized for transiting the Strait of Hormuz. Hours later, the Singapore-flagged container ship Ever Lovely was struck by an unknown projectile 7.5 nm off Oman’s coast. The incident prompted the International Maritime Organization (IMO) to suspend its evacuation program for stranded vessels, citing the need to reconfirm safety guarantees.
Background & Context: Interim MoU and Shipping Disruption
On 14 June the United States and Iran signed a memorandum of understanding (MoU) that opened the strait for “toll-free” commercial traffic for 60 days while de-mining operations proceed. The agreement follows a four-month U.S.–Israel war on Iran that saw the strait effectively closed and global oil flows disrupted. Oman, coordinating with the IMO, announced a new southern corridor on 24 June to restore navigation, a move the IRGC called “unacceptable and dangerous.”
Key Figures & Groups
- IRGC Navy – issuing the route warning and threat of action.
- Marco Rubio – U.S. Secretary of State, defending free navigation.
- Arsenio Domínguez – IMO Secretary-General, pausing the evacuation plan.
- Ali Vaez – International Crisis Group project director, monitoring compliance.
- Badr Albusaidi – Omani Foreign Minister, rejecting transit fees.
- Persian Gulf Strait Authority (PGSA) – Iran’s body overseeing strait traffic.
Timeline
- 28 Feb 2026 – U.S.–Israel strikes begin; Iran closes Hormuz.
- Apr 2026 – IRGC publishes a map pushing ships closer to Iran’s coast.
- 14 Jun 2026 – U.S.–Iran MoU signed (60-day toll-free period).
- 24 Jun 2026 – Oman announces new southern route with IMO coordination.
- 25 Jun 2026 – IRGC warning issued; Ever Lovely struck; IMO pauses evacuation.
- 26 Jun 2026 – Rubio reiterates opposition to any tolls; Domínguez confirms pause.
Data & Statistics
- Roughly 20 % of global oil and LNG transit the strait (? 20 million bbl /day in 2025).
- Pre-war traffic: 120-140 vessels/day; 25 Jun 2026: 70 vessels (Kpler).
- 131 vessels crossed between 22-25 Jun 2026 (Kpler).
- Brent crude fell to $72.24 / bbl on 25 Jun, still above the pre-war low of $66.
- Iran’s proposed service fees could generate ? $40 billion / year (Wall Street Journal).
Why It Matters / Impact
Control of Hormuz remains Iran’s most potent leverage over global energy markets and U.S. political calculations ahead of the November midterms. A shift toward Iranian-approved routes or tolls could reshape shipping costs, affect Gulf economies, and test the durability of the interim peace framework.
Official Statements & Responses
- The IRGC declared any uncoordinated route “unacceptable and poses serious safety risks.”
- Rubio warned that “no country on Earth has the right to charge for the use of international waterways.”
- Domínguez said the evacuation pause is “to reconfirm that the necessary safety guarantees continue to be in place.”
- Albusaidi emphasized that future arrangements “do not involve imposing any transit fees.”
- Vaez cautioned that imposing fees would violate the MoU and jeopardize negotiations.
Criticism & Opposition
Gulf Cooperation Council members, the U.S. Treasury, and Oman have all rejected any toll regime, labeling it a breach of international law. Analysts note that persistent IRGC rhetoric could deter shipowners despite the MoU’s guarantees.
On-the-Ground Reports
MarineTraffic recorded 31 verified crossings on 25 Jun, with several vessels performing U-turns after IRGC radio warnings. The Ever Lovely sustained bridge damage but no casualties or environmental impact.
Conflicting Reports & Gaps
Sources differ on whether the struck vessel was part of the IMO evacuation list. While U.S. officials attribute the attack to the IRGC, the IMO has not confirmed the perpetrator. The exact timeline for de-mining and the post-60-day governance model remain undefined.

- “Navigation outside these routes is highly dangerous and prohibited, and we warn all vessels to strictly avoid any movement outside the designated corridors,” — IRGC Navy, local media
- “No country on earth has the right to charge for the use of international waterways, and that will never be an acceptable condition of any deal,” — Marco Rubio, press conference in Bahrain
- “I have decided to temporarily pause [the evacuation plan’s] implementation in order to reconfirm that the necessary safety guarantees continue to be in place for the ships on our evacuation list and all those in the region,” — Arsenio Domínguez, IMO statement
- “The important thing now is that the Iranians do not start taking fees or other tolls,” — Ali Vaez, interview
What’s Next
The 60-day negotiation window ends in mid-August, when parties must decide on de-mining completion, the legal status of tolls, and a permanent governance structure for Hormuz. The IMO will reassess its evacuation plan once safety assurances are verified, while regional navies remain on alert for further incidents.
