Iran-Oman Strait of Hormuz Deal: What's Agreed, What's Not, and Why It's Still Blocked

The proposed Iran-Oman agreement to reopen the Strait of Hormuz is the most advanced diplomatic track to restore shipping through the world's most important oil chokepoint — but it has not been signed or implemented. As of early August 2026, negotiators have agreed on geographic coordinates for a new shipping route and are finalizing a joint announcement. However, the deal remains blocked by three fundamental disputes: transit fees, the exclusion of U.S. and Israeli vessels, and the U.S. naval blockade. Meanwhile, the Islamic Revolutionary Guard Corps (IRGC) has continued attacking commercial ships even as talks progress.

Background: How the Strait of Hormuz Closed

The Strait of Hormuz was effectively closed starting in late February 2026, triggered by U.S. and Israeli military operations against Iran. Iran retaliated by asserting control over the waterway via threatened and actual attacks on commercial shipping . An April 7, 2026, ceasefire halted major combat , but the strait remained closed or heavily contested. Iran has repeatedly declared it closed, most recently on July 11, 2026, after firing a warning shot and saying any unauthorized vessel would be hit .

Current Status of the Iran-Oman Agreement

No final deal has been signed, but several milestones have been reached:

• Route coordinates agreed: On August 5, Iran's Foreign Ministry said it had reached an "understanding" with Oman on geographic coordinates for a new shipping route through the strait, with a joint announcement in the final drafting stage .
• "Very close" but conditional: On August 8, Iranian Foreign Minister Abbas Araqchi said Iran and Oman were "very close" to agreement but that reopening the strait depends on other conditions, including U.S. compensation to Iran S.
• Iran says a joint deal alone is not enough: Broader U.S.-Iran issues remain unresolved, and Tehran has made clear that a bilateral agreement with Oman will not by itself reopen the waterway S.

Proposed Shipping Control Structure

The emerging plan creates a dual-lane system that gives Iran significant authority over inbound traffic:

• Dual-lane, Iranian-controlled inbound: Under the emerging plan, vessels entering the Gulf (inbound) would use a route in Iranian waters under Iranian control. Vessels exiting the Gulf would use a route in Omani waters under Omani oversight S.
• Iran demands "inbound control, outbound oversight": Iran wants control over all inbound shipping and the ability to intervene on outbound traffic if necessary S.
• Oman's alternative proposal: Oman originally proposed a joint regional management mechanism with voluntary fees, backed by Gulf states , but the current talks lean toward Iran's more assertive control model.

Disputed Fees: The Central Sticking Point

Fees are arguably the most contentious issue. The three parties are far apart:

Party	Proposed Fee Structure
Iran	5–7% of cargo value
Oman	Around 3% of cargo value
United States	Zero — insists on no fees or impediments

• Iran's parliament is also reviewing a draft bill that would fine violators up to 20% of cargo value for unauthorized passage .
• Oman's position called for "voluntary fees" to fund navigation, environmental, and rescue services — not a mandatory toll .

Conditions: Ban on U.S. and Israeli Vessels

Iran has made the exclusion of American and Israeli ships a non-negotiable demand:

• Iran insists on banning U.S. and Israeli ships from transiting the strait. According to Iranian state media, the deal "prohibits any American or Israeli vessels" from passing through S.
• An Iranian parliamentary committee is reviewing a draft bill that would bar U.S., Israeli, and other "hostile" vessels, and impose fines of up to 20% of cargo value on violators .
• Iran also demands that the U.S. end its naval blockade of Iranian ports as a condition for reopening S.

IRGC Attacks Despite Talks

Attacks on commercial shipping have continued throughout negotiations, severely undermining trust:

• April 22, 2026: Iran attacked at least three commercial ships hours after President Trump extended a ceasefire .
• July 7, 2026: A Qatari LNG tanker was at risk of exploding and a Saudi crude tanker was damaged near the strait; the maritime threat level was raised to "severe" .
• July 11, 2026: The IRGC again declared the strait closed after firing missiles and drones at vessels .
• Top IRGC officers close to the Supreme Leader have reportedly approved using force to secure Iranian control over the strait, complicating the negotiating track .

U.S. President Trump's Involvement and Claims

• Trump publicly described U.S.-Iran discussions as "very good" on August 5 S.
• The U.S. has been indirectly involved in the Iran-Oman talks, with the firm position that temporary routes must operate without any tolls or impediments .
• The U.S. insists Iran must publicly commit to stopping attacks on ships and opening all lanes with no fees .
• There is no independent evidence that a breakthrough has occurred — Trump's positive statements contrast with Iran's continued demands for compensation, bans on U.S./Israeli vessels, and ongoing IRGC attacks.

Bottom Line

The Iran-Oman agreement is close on paper — route coordinates are agreed and a joint statement is being drafted — but it has not been signed or implemented. The deal remains blocked by three fundamental disputes: Iran's demand for 5–7% cargo fees (vs. Oman's ~3% and the U.S. insisting on zero), Iran's demand to ban U.S. and Israeli vessels entirely, and the lack of a U.S. commitment to end its naval blockade. Meanwhile, the IRGC has continued attacking commercial ships even during talks, and the strait remains effectively closed to normal commercial traffic.
