Introduction

Recent developments in US-Iran talks on ceasefire and nuclear issues have brought the Strait of Hormuz back into global focus. Iran‘s Fars news agency reported that the MoU was amended at the final stage, explicitly stating that Iran and Oman jointly exercise management rights over the Strait. Meanwhile, Trump sent mixed signals - “agreement completed” and “strait free” - raising questions about the substance, implementation, and regional security.

As a key global energy chokepoint, the Strait’s stability affects not only the Middle East but also international crude, LNG, and shipping insurance markets. The information from this agreement reflects both a phase of US-Iran rapprochement and deep competition over nuclear issues, maritime passage rights, and regional influence.

1. Strait of Hormuz Management Dispute: From Passage to Fees

According to reports, the latest MoU text specifies that “future management of maritime shipping services in the Strait of Hormuz” will be jointly decided by Iran and Oman. Notably, the phrase “maritime shipping services” implies US recognition of Iran’s right to charge fees for services to passing vessels.

From international law and realpolitik perspectives, this change is significant. The Strait has always been one of the world’s most sensitive strategic waterways. Any arrangement involving fees, inspections, insurance, and passage security will be seen as a reconfirmation of regional power structure. If Iran can incorporate “passage safety,” “navigation support,” “environmental protection,” and “insurance services” into revenue sources, it gains not only military influence but also institutional and economic space.

According to Iran, it only agreed to a 60-day free passage for vessels; after that, it will formally charge for services to fund national economic development. If true, this shows Iran wants to convert strait control into a sustainable fiscal and policy tool, with Oman playing a coordinating role buffering regional conflict.

2. US Statements vs. Reality: “Agreement Completed” Does Not Mean Risk Gone

Trump claimed on social media on the 14th that the US-Iran agreement “is now complete,” authorizing the Strait of Hormuz to be “free and open,” and that the US Navy immediately lifted its blockade. Such statements continue his high-profile style, but follow-up indicates implementation is not smooth.

Iran later stated that over 96 hours, the Islamic Revolutionary Guard Corps Navy had not issued any passage permits, and the Strait remained closed to all vessels. Meanwhile, ship tracking showed only the LNG carrier “Disha” passed through into the Gulf of Oman, becoming the first large energy carrier after the deal.

This shows that even if political consensus is reached, actual execution is constrained by security assessments, maritime management, and shipping company risk appetite. For shipowners and operators, true stable passage depends not on political statements but on clear institutional arrangements, predictable implementation, and manageable conflict risk.

3. Nuclear Issue Loosens: Trump’s Concession Signal on “Low-Level Enrichment”

Alongside the strait issue, more contentious nuclear topics are moving. Trump told the New York Times that Iran would be allowed limited low-level uranium enrichment, with the new agreement ensuring Iran’s enrichment “can only be for non-military purposes forever.” Iranian media interpreted this as a substantial US concession on the “zero enrichment” demand.

Previously, the US demand for a full stop to enrichment was a core obstacle. Trump‘s shift to accepting limited, controlled, low-level enrichment indicates an adjustment in the US position from “absolute zero.” This reflects both realpolitik compromise and Iran’s retained bargaining leverage under prolonged pressure.

However, Trump also emphasized “strong supervision” and near-instant inspection mechanisms, not allowing months-long delays like the 2015 deal. This shows the US, while flexing on some terms, still tries to maintain constraints via strict verification. The problem is Iran’s distrust of the US, which has reneged on promises before. Even if text approaches each other, building genuine trust remains difficult.

4. Agreement Prospects Still Limited: Regional Politics and Strategic Doubts Persist

From available information, the Iran-US MoU appears more a phase de-escalation tool than a final settlement. The Strait issue involves energy security, maritime sovereignty, regional order, and great power competition; the nuclear issue touches Iran’s national security bottom line and US Middle East strategy. Their intertwining means any detail could trigger chain reactions.

Trump also mentioned possible military strikes and even a “Guardian of the Middle East” transaction rhetoric, increasing doubts about stability. Iran’s Tasnim news agency noted Trump’s remarks mean he has abandoned previous excessive demands, but for a real deal, the US needs more concessions. Given mutual distrust, final implementation remains uncertain.

Conclusion

Overall, this Iran-US MoU sends two important signals: first, the management and revenue distribution of the Strait of Hormuz are moving from pure military confrontation to institutional bargaining; second, the nuclear talks show partial relaxation, with the US stepping back from “zero enrichment.” However, signal improvement does not equal risk elimination. The ambiguity of the text, uncertainty of implementation mechanisms, and accumulated distrust determine that this process will still be fraught with reversals.

For the international community, what truly matters is not a party announcing “agreement completed” in the media, but whether the Strait of Hormuz can resume stable passage, whether regional security can form sustainable mechanisms, and whether nuclear issues can balance verification transparency with national security. In the coming period, US-Iran relations may temporarily cool, but moving from crisis management to genuine rapprochement requires greater political courage and clearer institutional commitments.
