Iran-Oman MOU Framework Set, US Vows to Lift Port Blockade Once Deal Announced; Saudi-Pakistan-Turkey Defense Pact Signed; Adnoc Says 15 Vessels Hit Since War Start; Iran Threatens Gulf Energy/Water Strikes if Mediation Fails; Brent ~$82

0. Weekly Arc

The week ran from Trump’s Aug 1 conditional cancellation of a strike wave and repeated “deal imminent” signals, to Iran’s publication of a draft plan banning US and Israeli ships with fines up to 20% of cargo value, Tehran’s claimed strike on “enemy targets” near the strait, and a US official now saying a deal is expected soon with the port blockade to be lifted. Today the Iran-Oman MOU framework is clarified, Saudi Arabia, Pakistan and Turkey signed a joint defense pact, Adnoc disclosed 15 vessels hit since the war began, and Houthi attacks escalated in Yemen. Brent swung from the high-$70s to $83.5 and back to ~$82. Net: converging deal architecture, contested and hardening terms, no sealed agreement.

1. Situation Overview

The past 24 hours pushed the diplomatic mechanism forward while the military and internal-political layers hardened. Iran’s parliament national-security committee spokesman Hassan Kashkavi said Iran and Oman have clarified the general framework of a Hormuz-shipping MOU, with final text and details to be announced soon (8/7) ^[1]; a US official told Reuters “there is progress between Oman and Iran on the strait, and we expect a deal soon,” adding that once an agreement restoring unhindered commercial shipping is announced, “the United States will lift the blockade of Iranian ports,” with US actions remaining performance-based ^[2][1]. Yet no deal is sealed: an independent oil-flow track concludes “there’s no Hormuz deal, latest proposal untenable” (single source / unverified) ^[3]; Iran’s hardliners are pushing clauses banning US and Israeli vessels and moving to impeach Foreign Minister Araghchi ^[1][4]; and an unnamed senior Iranian official warned Gulf states that if they cannot persuade Trump to stop military action and shift to negotiations, Iran will strike their oil, electricity and water infrastructure ^[1]. Physically, Adnoc disclosed three vessels attacked this week — its war tally now 15 ^[5]; Houthi attacks claimed this week killed dozens in Yemen and targeted Saudi tankers ^[6][7]; and Brent holds near $82 after a ~4% prior-session gain ^[1][4], with Citi characterizing it as back around $80 ^[8]. Net change: escalating terms and military pressure alongside unsealed diplomatic progress.

2. Key Parties’ Positions

• [ESCALATED] Negotiation progress: Iran’s parliament security committee spokesman Hassan Kashkavi said on 8/7 that Iran and Oman have clarified the general framework of the Hormuz-shipping MOU, with the final text and details to be announced soon ^[1]; per Citi, the latest Iran-Oman draft includes a 60-day transition period ^[8]; an anonymous Iranian government official told US media the agreement is designed to return US-Iran talks to the mid-June memorandum, launching a new 60-day round during which transiting vessels would pay “no fees or tolls” ^[4]. Per mediator officials cited by Reuters, Foreign Minister Araghchi and Speaker Ghalibaf had earlier accepted Oman’s proposal over the weekend, but the IRGC insists on “a clearer and more explicit mention of Iran’s role and interests” — including retaining Iran’s right to collect tolls and seeking clearer US guarantees to lift the blockade and oil-sales sanctions ^[4]. The core disagreement is unchanged: Iran remains firm on a toll of up to 7% of cargo value, Oman has asked for about 3%, and Washington wants zero ^[9][4]; India and China are seeking further discounts ^[9]. Arab mediators worry Iranian diplomats may be unable to ensure effective implementation, with Tehran’s negotiators under hardliner pressure for more explicit terms ^[1]. Reuters assesses the Iran-Oman deal as crucial to a wider peace agreement, but notes it is unclear whether the latest flurry of negotiations will yield a more lasting arrangement ^[2].
• [EASED] US / main pressuring party: An anonymous US official said: “There is progress between Oman and Iran on the strait, and we expect a deal soon,” and made the most concrete US concession yet — “Once the deal is announced to restore commercial shipping without impediments, the United States will lift the blockade of Iranian ports,” with US actions staying “performance-based and tied to Iran’s implementation of its commitments” (per Reuters) ^[2][1]. The official reiterated that any temporary routes must involve “no approvals or permissions and no tolls or charges” ^[1][10][11]. Trump said on 8/6 the agreement “cannot yet be said to have been formally reached” but the strait is “to some extent open,” adding “We control there, but they could launch an attack at any time” ^[1]; he posted that the US military still has “massive amounts” of weapons being manufactured ^[11]. Treasury Secretary Bessent argued, per The Paper (澎湃新闻), that the strait will gradually lose strategic importance — that more than 50–70% of energy shipped via Hormuz will shift to underground pipelines and that within about two years the strait will become an ordinary waterway — while noting the strait will not return to its previous state given Iran’s attempt to control it ^[12]. The administration has ruled out any arrangement cementing Iran’s grip over the waterway, including fees ^[11]; U.S. officials have told mediators they will not accept Iranian restrictions or tolls ^[13].
• [ESCALATED] Iran / counterparty: Iranian leaders are betting that military pressure will ultimately force the US to accept their control of the strait, and that time is on their side, despite a battered economy, triple-digit food inflation and the December mass protests ^[14][15]; an adviser to Iran’s chief negotiator said “Iran is going after the enemy’s defeat — not an agreement” ^[14][15], Iran’s joint military command calls the strait an “unbreakable red line” ^[14][15], and Zarif wrote that Iran’s war achievements opened “an exceptional window for diplomacy” ^[14][15]. Iran is vowing to bar US Navy warships from transiting as part of any reopening agreement ^[13]. An unnamed senior Iranian official warned that if Gulf states cannot persuade Trump to stop military action and shift to negotiations, Iran will strike their oil, electricity and water infrastructure ^[1]. Hardliners are publicly attacking the negotiators: lawmaker Hossein-Ali Haji Deligani says he is collecting documents to impeach FM Araghchi ^[4]; Kayhan editor Hossein Shariatmadari called a reopening agreement “opening an escape route for the enemy” ^[4]; Speaker Ghalibaf mocked the White House’s “repeated threats and retreats” as “cyclical theater diplomacy” ^[1][10]. President Pezeshkian defended the talks on state TV, insisting most senior military commanders support them, and cited China as an example of securing rights through dialogue rather than conflict ^[2]; he told IRIB that communicating with the Supreme Leader is “very difficult” ^[4], and Iranian officials say communication with the Supreme Leader takes time ^[1]. Deputy FM Gharibabadi says the Oman talks are “in the final stages,” with unresolved demands including the US ending its blockade, lifting post-MOU sanctions, unfreezing Iranian assets and ending Israel’s invasion of Lebanon — and that the consensus “does not mean the Strait of Hormuz will be completely open,” with a “considerable portion” of traffic passing through Iranian waters ^[4]. Iran’s ambassador to China, Abdolreza Rahmani Fazli, said Iran “will definitely consider special treatment for the countries that were friendly to us and specially stood by us during the hard times” ^[9].
• [NEW] Israel: A Lebanese official said Lebanon and Israel have agreed on a shortlist of countries that could send troops to verify Hezbollah’s disarmament under a US-brokered agreement, with the United States to pick the countries from the list (8/7) ^[2]. Iran’s demand list for any broader deal includes ending Israel’s invasion of Lebanon ^[4]. No new Israeli military action is reported in this batch; the US continues trying to broker an end to the Israel-Hezbollah front ^[2].

3. Military Actions

• [NEW] US: CENTCOM has not reported any strikes on Iran since July 29 ^[2]; the US has reimposed its naval blockade of Iranian ports ^[10]; the US has resumed daily airstrikes, per AP and Crisis Group analyst Ahmed Nagi ^[6][7]; Sen. Mark Kelly cites the war as involving strikes on more than 14,000 targets ^[11].
• [ESCALATED] Iran: Adnoc reported three of its vessels were attacked by missiles and drones while transiting the Strait of Hormuz this week — bringing its total to 15 vessels hit since the start of the war; Adnoc says it is taking all necessary steps (8/7) ^[5]. Iran continues to fire on ships attempting to cross the strait without permission and its strikes have targeted Hormuz shipping; the regional conflict has brought Iranian missile fire onto Gulf oil exporters ^[2]. Per Newsweek, US bases in the Middle East are suffering frequent attacks from Iran’s asymmetric warfare, depleting US precision munitions while Iran rebuilds cheaper weapons faster than expected ^[4].
• [ESCALATED] Proxies (Houthis): The Houthis claimed a series of deadly attacks this week that have killed dozens of civilians and troops and targeted Saudi tankers transiting from Red Sea ports through the Bab el-Mandeb Strait to the Gulf of Aden ^[6][7]; SABA reports attacks on Saudi-backed military camps in eastern Yemen killed at least 17 soldiers ^[6][7]; the Saudi military says a Thursday attack injured 11 civilians, including a 4-year-old child ^[6][7]; one attack occurred in northeastern Yemen on Friday morning ^[6][7]. Spokesman Nasruddin Amer said the group will continue to target “any Saudi buildups” to lift the kingdom’s blockade on Yemen ^[6][7]; three Houthi officials told AP in July the group has planned for months how to disrupt shipping in the strait ^[6][7].

4. Strait of Hormuz Transit Status

• [ESCALATED] Control-status change: The emerging regime is now explicit. Per Fars citing a Foreign Ministry source, the draft envisages Iran taking the lead in controlling vessels entering the strait, with exports jointly supervised by Iran and Oman ^[1]; a “central corridor” would be opened, with the two currently limited-use routes discontinued within a “specific time” ^[1]; inbound vessels would pass through Iranian territorial waters and outbound through Omani waters ^[4], with outbound vessels needing to coordinate with Iran per US media ^[4]; Iran and Oman also discussed establishing a joint coordination center to guide maritime traffic ^[4]. Iran is vowing to bar US Navy warships ^[13]. The US counters that “no party controls the lanes or the ability to transit through them” in this international waterway ^[10], and the US military says the strait remains “free and open” for commercial vessels via a route it helps oversee near Oman’s coast ^[11]. Gharibabadi cautions the consensus “does not mean the Strait of Hormuz will be completely open” ^[4].
• [NEW] Transit data: Rory Johnston (single source / unverified) says Hormuz-exit oil flow is drifting higher, now trending above 5 MMbpd, as pre-MOU “dark trade patterns” reemerge (8/7 14:43 UTC) ^[3]; visible transit remains “extremely limited,” with only a small number of Middle East cargoes passing with US assistance and transponders off ^[1]. Lloyd’s List counts 84 transits last week (week of July 27) versus 45 the prior week — still far below the more than 700 transits of a typical pre-crisis week — with at least two ships hit in the strait in the past week and several other vessels reporting near misses or warnings from entities claiming to represent Iran’s Revolutionary Guard ^[11]. Vessel traffic remains far below pre-war averages, when 20% of the world’s oil passed through ^[10]; more than 1,500 commercial vessels have been laid up in the Persian/Arabian Gulf since February ^[16].
• [ESCALATED] Shipping / insurance signals: Iran is firm on a toll of up to 7% of cargo value, Oman has asked for about 3%, and India and China are seeking further discounts ^[9][4]. Eight major global shipping associations wrote to the UN Secretary-General and the IMO Secretary-General opposing tolls, calling mandatory transit or service fees a disguised toll; the Lloyd’s Market Association’s end-July clause auto-terminates war-risk cover for any vessel paying a transit fee; US sanctions on Iran’s Persian Gulf Strait Authority and Treasury prohibitions on accepting Iranian “security passage guarantee” services mean any related payment could lead to asset freezes — industry insiders call the toll mechanism operationally unworkable under sanctions and insurance terms ^[4]. Eurasia Group’s Gregory Brew estimates the plan could generate about $52 million per day (roughly $19 billion per year) if Hormuz traffic returns to pre-war levels ^[4]. Bypass activity is accelerating: the UAE has decided to cut its use of the strait to zero and announced a major expansion of its eastern ports on the Gulf of Oman, enhancing reliance on Fujairah ^[9]; Saudi Arabia is operating its East-West pipeline at full capacity and diverting crude to the Red Sea coast ^[9]; Iraq has started moving some crude overland to the Syrian town of Baniyas on the Mediterranean ^[9]; India is hoping the IMEC corridor will secure its energy needs ^[9]. Per The Paper (澎湃新闻), pre-war flow through the strait exceeded 20 million bpd versus current Saudi/UAE pipeline capacity of about 4.7 million bpd ^[12]. Fitch says Kuwait’s oil exports face sustained pressure because of their dependence on the strait ^[17].

5. Asset Implications

Asset	Direction	Horizon	Driver	Anchoring fact
Brent crude	range-firm (~$82; headline-driven ±4% swings)	intraday / days	Deal-hope headlines (US “deal soon,” blockade-lift pledge) cap the premium; hardline draft bill, Adnoc hits, Houthi attacks and Iran’s infrastructure-strike warning re-inflate it; no physical flow recovery	§4 — Brent ~$82 after +~4% session; Citi base case $80 Q3-2026 / $70 Q4-2026 / $65 2027
Gold / precious metals	↑ (haven bid)	days	Regional escalation (Adnoc attacks, infrastructure-strike threats) and fading “time-machine” deal hopes support hedging; no fresh gold print in this batch	§6 — optimism-bias warnings vs. record equity streak
Global equities / risk sentiment	↑ (records) / fragile	days	Bessent/Trump deal signals drove oil down and stocks to records; each failed close re-snaps risk sentiment	§2 — Dow record closes Monday and Wednesday; stocks “blasted higher” on Bessent remarks before no deal emerged
USD / haven currencies	→ (mixed)	days	Deal optimism trims haven demand; gasoline above $4/gal and inflation pass-through keep partial hedge flows	§2/§4 — US gasoline surged above $4/gal; energy-price inflation persists
Energy / shipping value chain	↑ (structurally elevated)	weeks / months	Hormuz traffic far below pre-war; contested toll regime; octane/gasoline crack elevation and tight middle distillates; Kuwait’s exposed exports	§4 — Lloyd’s 84/week vs >700 pre-crisis; US ULSD ~27m bbl below seasonal; gasoline cracks elevated

Mechanism read: This is a premium contest between a paper deal and physical reality. Citi’s Aug 7 Oil Monitor notes the market’s worries about supply disruption are fading faster than physical supply concerns are rising, with Brent around $80 and a base case of $80 in Q3 2026, $70 in Q4 2026 and $65 in 2027 — a deal-plus-demand-easing path. But the physical layer is not recovering: visible transits remain extremely limited, Hormuz-exit oil flow is only drifting higher as “dark” (transponder-off) trade reemerges above 5 MMbpd (single source, unverified), the UAE has moved its own strait usage to zero, and full reopening is gated on Supreme Leader approval and a US blockade lift. The two-sided $80–85 tape embeds a high deal probability that can re-snap on a hardline veto, a failed announcement or a confirmed tanker strike — the pattern CNBC documents of repeated “deal imminent” claims followed by no deal.

The product layer is a physical supply story independent of the crude tape. Global octane supply has deteriorated — Middle East refinery runs fell from 10.4 mb/d in February to 7.3 mb/d in March–April before recovering to ~9.0 mb/d in August, Russian naphtha exports hit a 270,000 b/d low, and Indian alkylate exports collapsed — keeping gasoline cracks elevated while US retail gasoline sits above $4/gal. Middle-distillate inventories are tight: global middle distillates fell 8 million bbl to 309 million, with US ULSD about 27 million bbl below its seasonal average. Even a signed Hormuz deal would leave refining/product tightness and consumer-inflation pressure in place — which is why the “deal premium” and the “inflation premium” can coexist, and why Bessent’s pipeline-bypass thesis (more than 50–70% of flows to pipelines within two years) runs into capacity arithmetic: pre-war Hormuz flows exceeded 20 mb/d versus only ~4.7 mb/d of Saudi/UAE pipeline capacity today, and LNG, fertilizer and petrochemical flows cannot be pipelined. Rerouting also does not remove geopolitical risk.

6. Contrarian & Watch Signals

• Contrarian & tail risks: RBC’s Helima Croft warns of “tremendous optimism bias” — some investors see a deal as “a time machine” that resets the Middle East to its pre-war status quo, which she calls unlikely; Rapidan’s Bob McNally sees no broader durable US-Iran settlement (only possibly a narrow Iran-Oman management plan) and warns oil could shoot back to peak levels if escalation isn’t contained or inventory de-stocking dissipates optimism; Rystad’s Galimberti notes the fundamental difference is unresolved — Iran wants a service fee, the US wants pre-war free waters — and that avoiding a costly stalemate with prices back at April levels requires both sides to move red lines toward the center. The “no deal” read: one independent oil-flow track calls the latest proposal untenable — “it’s a mess” (single source) — and notes Iran does enough to keep ships wary without a full clampdown; multiple prior “imminent deal” claims have not materialized, and Supreme Leader Khamenei’s approval — a necessary prerequisite — remains unconfirmed. Hardline blowback could hollow out any agreement: the impeachment drive against Araghchi, the IRGC’s insistence on retaining toll rights and clearer US guarantees, Kayhan’s “escape route for the enemy” framing, and negotiators’ own admission that the IRGC may escalate attacks on vessels again if a deal isn’t profitable enough. Dual-chokepoint tail: if ships fear Bab el-Mandeb enough to avoid it, two of the world’s most important routes are effectively disrupted at once, and if Iran forces payment for safe passage, the precedent could embolden the Houthis to block Bab al-Mandab. US leverage erosion: experts say advanced-missile-interceptor inventories are running short, US regional bases face frequent asymmetric attack, and Iran’s leaders calculate that time is on their side — while the counterweight is Iran’s own economics (triple-digit food inflation, embargoed oil exports) and Zarif’s warning that without an early deal, internal unrest or renewed aggression after the US elections cannot be ruled out. Second-order: the 1,500+ biofouled vessels laid up in the Gulf could become a biosecurity “super-spreader” when the strait reopens; bypassing the strait also does not bypass geopolitical risk.
• Key watch signals: Whether Khamenei approves the plan — the necessary prerequisite for the MOU to advance — and whether the Iran-Oman final text/joint statement is actually released; whether the US follows through on lifting its port blockade (the stated Iranian condition for full reopening). Whether Iran’s parliament advances the draft bill banning US/Israeli vessels with fines up to 20% of cargo value, and whether the impeachment effort against Araghchi proceeds. Visible Hormuz transits versus the >5 MMbpd dark-flow estimate (single source): a sustained rise in visible traffic toward tens of vessels per day confirms reopening mechanics; continued dominance of dark flows confirms the market is pricing a paper agreement (Lloyd’s 84/week vs >700 pre-crisis is the baseline). Brent: a sustained hold above ~$85 on a failed deal or confirmed tanker strike confirms premium re-inflation; a break below ~$80 on a signed, workable deal confirms the unwind — Citi’s $80/$70/$65 path is the bear anchor, an April-level spike the bull tail. Bab el-Mandeb tanker transits (Kpler shows fewer since this week’s attacks) and whether US daily airstrikes deter or provoke the Houthis. Whether Gulf states’ mediation secures a Trump commitment to halt military action — the trigger condition of Iran’s infrastructure-strike warning.
• Source quality control: Rory Johnston’s “no deal” and >5 MMbpd dark-flow figures are a single-source social post (single source / unverified) — directional intelligence, not a measured flow. The key US statements (“we expect a deal soon”; the blockade-lift pledge) come from an unnamed US official via Reuters; the Iranian infrastructure-strike warning is from an unnamed senior official; the claim that Araghchi and Ghalibaf accepted Oman’s proposal rests on unnamed mediator officials (via WSJ, as relayed by The Paper). Houthi attack claims are unverified; only SABA (Yemen government-affiliated) and Saudi military casualty figures corroborate them; Adnoc’s 15-vessel tally is a primary company statement. Draft-bill details (US/Israeli-vessel ban, 20% fines) come from Iranian state media (Fars) and are unconfirmed by any party. There is a direct conflict in the batch: the anonymous US official “expects a deal soon,” while the oil-flow track says “there’s no Hormuz deal” — the market is effectively choosing one; Citi’s price path is an explicit projection.
