Hormuz Control Fight Shadows US-Iran MoU Revival Push

Mediators from Pakistan, Egypt and Qatar have advanced a proposal that Iran and Oman have already accepted to revive the June Islamabad Memorandum of Understanding between the United States and Iran, according to sources familiar with the talks. The plan targets disagreements over the Strait of Hormuz so both sides can restart negotiations before the original 60-day window expires next month. President Donald Trump is expected to decide after his Tuesday meeting with Israeli Prime Minister Benjamin Netanyahu. Tehran has publicly denied seeking any new talks.

The second-order stakes sit in the fine print on coastal control and future fees. A short-term reopening would calm shipping. The lasting fight is over who sets the rules for the world’s most important oil chokepoint once the temporary no-charge period ends.

The Fragile Framework That Collapsed Mid-Summer

The Islamabad Memorandum was signed remotely on 17 June 2026 by Trump at Versailles and Iranian President Masoud Pezeshkian in Tehran, after Pakistan-led mediation. It was a 14-point framework, not a final treaty.

1. 17 June 2026: Remote signatures end the immediate fighting phase and reopen commercial traffic through Hormuz with no charge for 60 days only.
2. Late June: US waives oil-export sanctions for 60 days; some tanker traffic resumes.
3. Early July: Iranian attacks on ships and US strikes follow; Trump signals the MoU is over.
4. 18 July: Deputy Foreign Minister Kazem Gharibabadi announces Iran has suspended its commitments, citing US violations.
5. Late July: Mediators return with a clarification proposal as the original clock winds down.

Point 5 of the full 14-point Islamabad MoU text required Iran to arrange safe passage with no charge for 60 days only and to hold dialogue with Oman on future administration and maritime services “in line with the applicable international law and the sovereign rights of coastal states.” That language is the core of the current dispute. Point 6 floated a $300 billion reconstruction fund. Point 11 promised access to frozen Iranian assets once implementation began.

Implementation never stuck. Shipping recovered partially then stalled again amid renewed strikes.

The sequence shows how quickly a framework without enforcement can unravel. Remote signatures bought a pause. The sanctions waiver and partial tanker rebound followed. Then attacks and counter-strikes erased the gains, and the suspension announcement locked the breakdown into public view. Mediators now treat the late-July clarification push as the last practical chance to restart inside the same arithmetic the original text created.

Mediators Advance a Clarification Formula

According to an Arab official and a second source speaking to The Times of Israel, the current proposal aims to bridge the exact gaps that stopped talks. Iran has argued the MoU already gave it a level of control over the strait. The United States has rejected that reading.

• Pakistan, Egypt and Qatar have driven the shuttle diplomacy.
• Iran and Oman, both littoral states, have given the green light.
• The White House held its decision until after the Netanyahu meeting.
• If approved, technical talks could restart inside the remaining window of the original MoU.

Oman has floated formulas for joint management, including voluntary fees and shared corridors. Iran has rejected equal splits and any southern route outside its preferred control.

The diplomacy works because the three mediators carry different leverage. Pakistan led the original Islamabad process. Egypt and Qatar add regional weight and quiet channels. Oman’s dual role as littoral state and facilitator gives its formulas practical force even when Tehran rejects the equal-split versions. The green light from Iran and Oman therefore matters more than a simple procedural nod. It signals both coastal parties will at least sit with a clarification text before the original free-passage period expires.

What Trump and Netanyahu Said

The closed-door Oval Office session on 28 July lasted roughly 90 minutes. Both sides called it positive and productive. Netanyahu told Israeli media afterward that the leaders shared “an understanding of a shared goal, to ensure that Iran does not have nuclear weapons, and other goals as well.” White House statements echoed the language of partnership and coordination.

Neither side announced a decision on the mediators’ Hormuz proposal. Earlier reporting had indicated Trump wanted Netanyahu’s input before moving. Public comments stayed on the nuclear red line and the broader relationship rather than the MoU’s revival mechanics.

The silence on Hormuz itself is deliberate. Nuclear language is the public frame both leaders can own without conceding ground on coastal fees or corridor control. The input Trump sought still covers the MoU track even if the readout never named it. Markets and mediators will read the next White House move against that 90-minute session whether or not any joint statement mentions the strait.

Iran’s Public Line Stays Firm

Deputy Foreign Minister Kazem Gharibabadi has repeatedly denied that Tehran initiated contact. “Iran has not made any requests for negotiations or ceasefire with the US in the past 17 days,” he said. He added that the United States had “desperately requested dialogue” via Oman and offered assurances against military measures. Gharibabadi also rejected an Omani invitation for a third country to clear mines in the southern strait.

Iran will consider any action to maintain control over the Strait of Hormuz, including the resumption of war.

Gharibabadi delivered that warning as the Trump-Netanyahu talks unfolded. On X and in Iranian media, he restated that vessels must pass under Iranian-preferred arrangements and that the strait would stay closed if those terms were refused. Crowds online noted the consistency: Tehran treats Hormuz control as non-negotiable while denying it is the party chasing a deal, preserving domestic and regional face.

The dual message serves a single purpose. Denial of initiation protects the narrative that Washington is the side seeking relief. The control warning keeps pressure on shippers and on any clarification text that might dilute Iranian lead over preferred corridors. Rejecting third-country demining in the south fits the same pattern. It blocks an alternative route that would weaken the northern arrangements Iran wants to keep under its hand.

The Fee and Control Fight Underneath

The surface issue is whether the 60-day no-charge window can be restarted so formal talks resume. The second-order issue is the precedent for permanent rules.

The official MoU paragraphs on Hormuz explicitly limited the free period to 60 days and pointed future administration to Oman and other Persian Gulf littoral states. That drafting left both sides room to claim victory and then clash. Any clarification that freezes a joint or Iranian-led fee structure would give Tehran recurring revenue and leverage. A clarification that locks free passage would strip that tool.

This is why Oman’s rejected 50-50 corridor and southern-route ideas matter. They were attempts to split the difference. Iran’s answer was that one route must sit fully under its control and part of the second as well.

Every row in the dispute table traces back to the same drafting choice. Point 5 mixed a temporary free window with open-ended language on sovereign rights and littoral administration. Iran reads the sovereign-rights clause as already delivering coastal lead. The United States reads the free-passage tradition as still binding once the 60 days end. Clarification cannot please both readings at once. It can only freeze one of them into the next phase of talks.

Oil Flows and Who Pays if It Fails

Before the war, roughly 20 million barrels of oil and products moved through Hormuz daily, about one-fifth of global consumption, with around 100 ships a day. After the MoU, tanker crossings rose more than 200 percent in the first week, from just over six per day to more than 20, with peaks near 36. Volumes approached 20 million barrels on the busiest days before the collapse returned.

• Pre-war baseline: ~20 mbd and ~100 ships daily.
• Immediate post-MoU: sharp rebound then stalled recovery.
• Current risk: renewed closure or selective fees would spike insurance, freights and crude prices again.
• Secondary markets: crypto markets watching the Iran deal catalyst have already priced partial relief and fresh risk in recent weeks.

Gulf producers and importers in Asia feel the first shock. European refiners and global fertilizer and LNG trades follow. A durable fee regime would transfer wealth from shippers and consumers toward the coastal states that collect. A durable free regime would protect volume but leave Iran without the economic payoff it expected from the original text.

Earlier reporting on earlier odds on Islamabad peace talks already showed markets treating every mediation headline as a volatility event. The same pattern is repeating.

Gulf States and the Permanent Precedent

Oman sits on the southern shore and has spent years positioning itself as the indispensable facilitator. Pakistan, Egypt and Qatar have invested diplomatic capital in the Islamabad process. Saudi Arabia and the UAE have watched oil prices and missile risks while absorbing spillover strikes. The Gulf states absorbing strikes as oil climbed already demonstrated how quickly local infrastructure and global benchmarks move together.

If the mediators’ proposal succeeds, the clarification language will be studied for years as the new baseline for coastal-state rights versus transit freedoms. If it fails, the original MoU’s ambiguity becomes a cautionary tale about framework deals that promise both opening and sovereignty without choosing between them. Either outcome outlives the current 60-day arithmetic.

Reconstruction Money Hinges on Implementation

Point 6 of the Islamabad text floated a $300 billion reconstruction fund. Point 11 tied access to frozen Iranian assets to the start of implementation. Neither clause has moved because the Hormuz track never stabilized long enough for the money side to open.

That linkage still shapes incentives on both sides.

• Iran gains a path to large-scale reconstruction cash and unfrozen assets only if implementation is judged to have begun.
• The United States retains leverage over both the fund and the assets for as long as the control and fee fight blocks that judgment.
• Mediators know a pure security fix without an economic off-ramp leaves Tehran with less reason to accept lasting free-passage language.

A revived 60-day window would not automatically release the fund or the assets. It would only restart the clock on which those later clauses depend. Clarification language that settles coastal administration therefore carries a second payload. It decides whether the economic chapters of the original 14-point framework ever leave the page.

The Clock Forces a Binary Choice

The original free-passage period was always temporary. Sixty days of no charge bought time for Oman dialogue on future administration. That dialogue never produced an agreed fee or corridor model. The suspension in mid-July then froze the unfinished business inside a shrinking window.

Restarting the window does not erase the underlying choice. It only resets the deadline for making it.

1. Approve the clarification: technical talks resume, shipping gets another temporary calm, and the fee-control precedent gets written in clearer terms.
2. Reject or delay past expiry: the MoU’s free-passage chapter lapses, selective control and insurance spikes return, and the reconstruction and asset clauses stay dormant.

Trump’s decision after the Netanyahu meeting is the immediate gate. Iran’s public denials and control warnings set the floor Tehran will defend in any technical round. The mediators’ paper is ready either way. What the paper cannot do is keep both the temporary calm and the permanent ambiguity alive past the next expiry.

Trump still holds the final US card. Netanyahu has restated the nuclear red line. Iran has restated control of the waterway. The mediators have a paper ready. The deeper contest over who writes the long-term rules for Hormuz continues whether or not the signatures resume this week.
