The temporary shipping corridor led by Iran and Oman is moving from a paper concept into a difficult operational contest. Over the past 24 hours, Iran's Revolutionary Guards claimed agreement on passage shares and revenues, then accused Washington of deliberate delay and obstruction. The deputy foreign minister laid out plans to close the existing southern route. Crude came under pressure for a third consecutive day. Tehran simultaneously pursued UN complaints, nuclear-inspection disputes and Russian cooperation to counter the shock of Washington's economic-isolation campaign.

Gulf mediators were also moving faster. Qatar's foreign ministry announced that the prime minister would visit Tehran on Thursday for important mediation on de-escalation and freedom of navigation in Hormuz.

Hormuz Corridor: Implementation Details Come into Focus

Iran's proposed rerouting through its waters, closure of the southern route and mine-clearance hurdles.

A new arrow shows both directions rerouted through Iranian waters; passage shares and revenues are described as agreed. The southern route is crossed out as due to close, while a US label says obstruction continues. Bottom: mine clearance and intelligence sharing are decisive. These are attributed Iranian proposals and claims, not confirmed operating arrangements.

Iranian messaging is becoming more operational. A Revolutionary Guards spokesman told Tasnim that the two countries had agreed on their respective shares and revenues in strait waters, but then accused the US of obstructing and delaying implementation.

Deputy Foreign Minister Gharibabadi elaborated on Press TV: once an agreement was finalized, the UN-authorized southern route along Oman's coast, which handles most current traffic and which Iran has long opposed, would close. Ships in both directions would instead pass through Iranian territorial waters. Oman's earlier joint statement, however, mentioned no such change, while Washington continued to call Hormuz international waters. Whether the US would tolerate an exclusive corridor entirely through Iranian waters remained highly uncertain; Trump had even publicly threatened strikes on Oman the previous week.

The US response was equally forceful. Trump reiterated that mines in the strait had been cleared or detonated, warned that any vessels attempting to lay more would be systematically destroyed, and said the military was monitoring every square inch. On Monday, the Treasury warned global shipping firms that even complying with requests for information from Iran's strait-management authorities could very likely trigger secondary sanctions.

Beyond politics, mine clearance poses a practical technical hurdle. Chatham House researcher Laub argued that although Iran has some mine-clearing tools, its mine-warfare system was built mainly for laying mines and is poorly suited to precise, large-scale clearance in deep water. Senior UN demining expert Heslop said clearance requires sophisticated sensors and highly specialized explosive-ordnance teams, making it costly and laborious. Iran's willingness to share mine coordinates would be decisive: without that information, other countries could not operate on equal terms. Laub added that political promises such as the June memorandum were insufficient to normalize the strait; declaring it open neither removes underwater hazards nor restores shipping and insurance confidence.

Diplomacy intensified accordingly. After meeting Araghchi in Tehran, Omani Foreign Minister Badr expressed optimism that the two countries would formally announce a temporary corridor soon. Doha sent another significant signal: Qatar announced that Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman would visit Tehran on Thursday to discuss concrete ways to reduce confrontation and restart dialogue. Talks would cover free passage through Hormuz and the need to return to conditions before the February 28 war. Qatar had maintained public support for the Iran–Oman plan even after Trump's threat to attack Oman.

Oil Falls for a Third Day: Hopes for Passage Outweigh Threat Premiums

Oil-price declines, Hormuz's global role, Iranian gas losses and US gasoline costs.
Original Chinese illustration · English guideOil falls for a third day as hopes of passage outweigh threat premiums. Brent near $86 per barrel, -3%; WTI $80, -2.8%; weekly cumulative losses -9% and -8%, respectively. Hormuz normally carries about 20 million barrels per day, roughly 20% of global consumption. Bottom: petrochemical shutdowns accompany roughly 230 million cubic meters per day of lost gas capacity; US gasoline is $4.10 a gallon.

Markets quickly priced the prospect of a breakthrough in navigation. Before 06:00 US Eastern time on Wednesday, Brent futures fell 3% toward $86 a barrel and WTI 2.8% to $80. Both declined for a third day, taking weekly losses to 9% and 8%, respectively, largely reversing the geopolitical premium generated by Bessent's economic D-Day rhetoric. Deutsche Bank analysts said traders remained in a wait-and-see mode without operational details or a timetable. The Guards' claims of agreed shares and US obstruction caused little market response.

Hormuz's global importance is clear. EIA data show roughly 20 million barrels of crude normally pass daily, around one-fifth of world consumption, alongside nearly one-fifth of global LNG trade. Flows collapsed at one stage after the conflict began. Every detail of the route and who clears obstacles therefore affects energy markets.

Iran's supply and industrial systems showed strain. Extreme heat and electricity shortages forced several plants in the southwestern petrochemical hub of Mahshahr to stop. Arvand Petrochemical halted from August 22, and downstream Ghadir Petrochemical was also ordered shut by the National Petrochemical Company. Tehran acknowledged that fighting had destroyed about 230 million cubic meters per day of gas capacity. Repairs at key Asaluyeh facilities sought first to restore roughly 95 million cubic meters per day of basic supply.

US consumers also felt inflation pressure. AAA estimated that the August national gasoline average would likely set a record for that month. Wednesday's regular-gasoline average was $4.10 a gallon, far above the prewar February 28 level of $2.98.

Sanctions Fallout: UN Letter, Siege Characterization and Enforcement Test

Iran's UN complaint, Israel's siege framing and doubts about sanctions enforcement against China's purchases.
Original Chinese illustration · English guideSanctions fallout in three panels. UN letter: Araghchi writes to the secretary-general and calls sanctions economic terrorism. Siege characterization: Netanyahu says pressure is tightening on those helping Iran. Enforcement test: China buys up to about 90% of Iran's oil exports, while no country is named and settlement banks are not targeted. The bottom relays the criticism that this mainly announces more future announcements. These judgments and accusations remain attributed.

Tehran sought to move the sanctions dispute onto the multilateral stage. Araghchi formally wrote to UN Secretary-General Guterres requesting systematic assessment and reporting of US sanctions' human-rights and livelihood effects. He called the measures economic terrorism, citing damage from unilateral sanctions and extraterritorial jurisdiction to food, medicine, health care, energy and transport, and urged an immediate end to US pressure on third countries and businesses. Speaker Ghalibaf remained defiant, asserting that Washington had lost the military and political war and would also fail at economic blockade.

Israel offered its characterization of Washington's strategy. Speaking in the West Bank, Netanyahu said Trump's measures tightened the siege around Iran, focusing on external channels supporting Tehran rather than directly closing it off. He said that during his late-July US visit he had offered three choices: a comprehensive agreement, renewed strikes or maximum economic pressure. Trump chose to pursue economic pressure very firmly. Netanyahu also warned that the Iranian threat was far from over.

The US sanctions package, presented as the toughest ever, nevertheless faced domestic scrutiny and doubt. Effective economic D-Day enforcement could not avoid China, which currently bought as much as 90% of Iranian crude exports. Yet Bessent's Monday announcement named no country and did not put major financial institutions helping settle China–Iran trade on the secondary-sanctions list. University of Michigan economist Wolfers was blunter: the major economic-isolation initiative amounted largely to announcing that more announcements would follow.

Nuclear and Russian Channels: Inspection Deadlock and a Nuclear-Power Memorandum

Iran rejects damaged-site inspections while signing a separate $25 billion Russian nuclear-power memorandum.
Original Chinese illustration · English guideNuclear and Russian channels. Inspection deadlock: Eslami accuses the US and Israel of pushing IAEA inspections of damaged sites, invokes wartime conditions and refuses access. Russian nuclear-power memorandum: $25 billion, with a new Persian Gulf site allocated and a leader meeting at the Bishkek summit the following week. The bottom distinguishes this from the June US–Iran memorandum: two separate documents.

On Wednesday, Atomic Energy Organization chief Eslami accused the US and Israel through state media of pressuring the IAEA to inspect damaged nuclear sites to assess military-strike damage. He said the agency had neither an existing agreement nor an official position and was being pushed by Washington and Israel to investigate on site. He rejected inspections, saying Iran was in wartime, damaged sites lacked safe conditions, sensitive inspections were governed by parliamentary legislation, and the IAEA had no statutory inspection procedure for attacked facilities. The agency had not publicly responded. Access to war-damaged nuclear sites was becoming another arena of confrontation.

Iran accelerated Russian cooperation in energy infrastructure and leader-level diplomacy. Mehr cited Iran's ambassador to Russia as saying the countries signed a $25 billion memorandum for new nuclear plants and allocated a dedicated Persian Gulf coastal site. President Pezeshkian was due to meet Putin at the following week's Shanghai Cooperation Organization summit in Bishkek. This project and the US–Iran framework memorandum signed in June are separate, unrelated documents.

Trump's Assessment and Tehran's Domestic Politics

Attributed claims about the supreme leader's health alongside Iranian media restrictions and military production.
Original Chinese illustration · English guideTrump's assessment and Tehran's domestic politics. Trump says he does not believe the supreme leader is dead, claims severe left-side, arm and leg injuries, and suggests officials may maintain the appearance of life. Domestic panel: legislation criminalizing foreign-media contact; a journalist sentenced to 15 years; air-defense production and drone lines restarting. Bottom: the supreme leader has not appeared for nearly six months and his whereabouts remain uncertain. The health claims are Trump's allegations.

In a Wednesday interview with conservative radio host Beck, Trump offered a vivid assessment of Iran's supreme leader's health. He said he did not believe the leader was dead but thought the left side, arm and leg had suffered devastating injuries. Trump further claimed that even if he had died, Iranian leaders would maintain the appearance that he was alive and invoke his purported supreme approval for major decisions. He also disparaged the negotiating team as unworthy of respect. Outsiders had followed the leader's condition for nearly six months, while Tehran remained silent. Trump cast US financial strength as the decisive advantage, claiming it could overwhelm any opponent.

Trump was pessimistic about regime change through street protests. He argued that protest could not persist against forces prepared to fire on crowds, and that rooftop snipers shooting a few leaders could disperse tens of thousands of demonstrators.

Tehran was tightening domestic social control. Parliament was advancing legislation to criminalize contact with hostile foreign media, prompting human-rights lawyers to warn of a new legal disaster. Some reformists argued that suppressing interviews could not hide governance failures. Photojournalist Yalda Moayeri, who had spoken out repeatedly, was sentenced this month to 15 years. Militarily, the army air-defense commander said lessons from the third imposed war were being converted into equipment capacity, with domestic technology expanding new defenses. Reports indicated that some drone production lines had already restarted during May's six-week ceasefire window.
