US strikes have now hit Tehran twice in two days, Iran is threatening to close the Red Sea via the Houthis if Trump hits its power grid, and Vance has gone on the record accusing Israel of running a covert influence campaign to keep the war going. The Memorandum of Understanding (MoU) is dead in practice. The Strait of Hormuz is closed. And now Iran is signalling it can make the Red Sea equally unusable, which would mean both of the Middle East's major oil export routes are simultaneously disrupted. The energy story just got significantly worse. ## Lead story: IRAN'S HOUTHI CARD, AND WHY IT CHANGES THE ENERGY CALCULUS ENTIRELY Here is the development that deserves more attention than it is getting. Iran has quietly instructed the Houthis in Yemen to stand ready to close Bab el-Mandeb, the gateway to the Red Sea, if the US strikes Iranian power infrastructure [6]. Three sources, including two senior Iranian sources and a regional source familiar with the discussions, told Reuters this is not a hypothetical: the Houthis have been specifically informed, missiles and drones have already been deployed to highland positions overlooking Hodeidah and the Gulf of Aden, and the trigger decision will rest with Islamic Revolutionary Guard Corps (IRGC) representatives already embedded in Yemen [6]. Let that sit for a moment. The Strait of Hormuz is already closed. Around a fifth of global energy exports previously moved through it. The Red Sea and its Bab el-Mandeb chokepoint is the primary alternative export route for the region. If Iran activates the Houthis against Red Sea shipping, both routes go down simultaneously. There is no third option. The supertanker traffic that has been rerouting around the Cape of Good Hope would face further capacity constraints, and the energy markets, already elevated, would face a shock of a different order than anything seen so far in this war. The trigger condition matters: this is explicitly conditional on a US strike on Iranian power infrastructure. Trump threatened exactly that on Tuesday [9]. He has not yet acted on it, but the threat is on the record and the Houthis are in position. Iran is telling Washington, in a language designed to be understood: hit our lights and we hit your oil routes. Both of them. The timing compounds the danger. The Houthis just fired missiles at Saudi Arabia this week, breaking a four-year truce with Riyadh [6]. Saudi Arabia, whose Red Sea oil export infrastructure is now in the crosshairs, is reportedly taking these threats "very seriously" [6]. Two regional sources close to Riyadh confirmed they are aware the Houthis are now tightly coordinating with Tehran on Red Sea operations. Riyadh has spent four years trying to exit the Yemen conflict. It may be about to find itself pulled back in, from a different direction, at the worst possible moment. The thing most people have missed in today's coverage is the Syria angle. The arms shipment intercepted at the Tanf crossing on the Iraq-Syria border included, according to the Alma Research and Education Center, at least 100 drones, optical fiber-guided systems, factory-prepared RPG warheads for drone mounting, anti-tank guided missiles, and what appear to be Paveh-family cruise missiles [3]. This was a Hezbollah resupply run. The fact that Syria's new transitional government intercepted it matters, but what matters more is that Iran is simultaneously managing a multi-front war, rearming Hezbollah, and positioning the Houthis for a potential Red Sea closure. That is a coordinated escalation architecture, not a series of unconnected incidents. ## ALSO NOTABLE - **US strikes hit areas around Tehran for a second consecutive day**, along with Bandar Abbas, Greater Tunb Island, and multiple provincial sites [9] [12]. US Central Command (CENTCOM) said its evening wave targeted Iranian command centres, air defence sites, missile and drone capabilities, and coastal surveillance facilities. Iran's Health Ministry reports at least 35 killed and more than 300 wounded since fighting resumed last week [12]. A cancer hospital in southwestern Iran was evacuated due to strikes nearby, which Iran's foreign ministry called a "barbaric attack" [9]. - **Iraq suspended crude loading at all terminals after a drone struck a tanker in Basra** without causing damage [9]. This is a significant escalation of the economic stakes: Iraq is not a party to this war, but its oil infrastructure is now at risk from Iranian drone activity in its own territory. Iraqi Prime Minister Ali al-Zaidi, who is in Washington this week, pledged to disarm non-state armed groups during his visit [9], even as Iraqi resistance faction Al-Nujaba Movement warned against energy deals with Washington [14]. Zaidi's government is simultaneously signing a pipeline deal with Chevron and being targeted by Iran-aligned militias. That tension is not going away. - **The Iraq-US pipeline deal is bigger than it looks.** A deal set to be signed Friday involves Iraq, Chevron, TI Capital, and Qatar's UCC to build a pipeline connecting Basra's oil fields to Turkey's Ceyhan port and Syria's Baniyas port [14]. This is Washington attempting to construct an alternative export infrastructure for Iraqi oil that bypasses the Strait of Hormuz entirely. If it ever gets built, it changes the strategic geography of the region permanently. The Houthi intercepted arms shipment passed through the exact same Iraq-Syria corridor this pipeline would use [3]. That is not a coincidence worth ignoring. - **Vance publicly called out Israel's influence campaign, in detail, on the Joe Rogan Experience.** He cited a Time Magazine investigation reporting that Brad Parscale, Trump's former campaign manager, was paid to run a digital influence operation targeting US conservatives to oppose the Iran deal [4] [10]. Vance's precise words: "When I see there's a literal foreign influence campaign being funded to tank the very deal I was pursuing, my response is 'go to hell'" [10]. He also ruled out 150,000 ground troops for regime change, and said the Hormuz problem can only be resolved diplomatically [10]. This is the Vice President publicly splitting from the Prime Minister of the US's closest ally while a war is ongoing. Arab leaders are meanwhile privately telling Trump that Netanyahu is "an obstacle to realizing his vision" [1]. The US-Israel relationship is under visible, sustained pressure from inside the White House. - **Iran formally warned Gulf neighbours to stop hosting US forces**, citing its legal right to self-defence under Article 51 of the UN Charter [5]. Tehran's message to Bahrain, Kuwait, Jordan, and others: you are legitimate targets as long as US forces operate from your soil. Iran already filed a 42-breach UN complaint against the US covering June 18 to July 13 [13]. The Security Council will not act on it. But Iran is building an international legal record with every document it files, which tells you Tehran is thinking past the current fighting. ## MARKETS & MONEY Brent is holding at $84.31, essentially flat from yesterday, which is the interesting signal. The market knows about the Tehran strikes, the Hormuz closure, the Houthi threat, and the Iraq terminal suspension, and it is not panicking. The Oil Volatility Index (OVX) has actually eased from 58.96 to 55.94, which suggests traders are treating the current situation as priced-in rather than accelerating. That complacency looks fragile given the Houthi Red Sea trigger that most market participants do not appear to have fully digested yet. RBOB Gasoline dropped slightly from $3.30 to $3.10 today, but it is still 9% above its level a week ago and heading for US pumps shortly. Gold is off its peak at $3,987, continuing a gradual retreat from $4,353 a month ago, which is unusual: falling gold during an intensifying war typically signals either dollar strength or forced selling elsewhere. The VIX at 16.58 is still historically calm. If the Houthi trigger gets pulled, these numbers will look very different by Monday. ## WESTERN IMPACTS US diesel is back above $5 a gallon according to the AAA, returning to its pre-MoU highs, and average gasoline is approaching $4, driven by the renewed fighting and a White House that, in the AAA's own description, moves markets "on whim" [8]. A year ago, diesel averaged $3.72. That dollar-and-a-quarter difference lands on every trucked consumer good in America. Brent at $84.31 is still below the war's peak, and the Guardian reports oil at around $81 at the pump-relevant wholesale level [8], but the trajectory is upward and the Houthi risk, if it materialises, would push it sharply higher. Heating oil at $3.92 versus $3.16 in mid-June is the number European households should be watching as summer ends. The Iraq-US pipeline deal, if it proceeds, is a long-term answer to Hormuz dependency, but it will take years to build. Nothing about that helps anyone this autumn. ## WHAT TO WATCH 1. **Whether Trump orders strikes on Iranian power infrastructure in the next 48 hours.** That is the explicit Houthi trigger. Iran has drawn a direct conditional line: hit our grid, and the Red Sea closes. Trump has publicly threatened exactly that. If he acts on it, watch for IRGC activation signals from Yemen within hours. The gap between the threat and the response, if it comes, will be very short. 2. **Friday's Iraq pipeline signing ceremony.** The deal between Iraq, Chevron, TI Capital, and Qatar's UCC is scheduled to be signed on Friday [14]. If it goes ahead as planned, it signals Washington has a coherent long-game strategy for regional energy rerouting. If it is delayed or quietly dropped, that tells you the security situation around the Iraq-Syria corridor, already demonstrated by the intercepted Hezbollah arms shipment, is too unstable to commit capital to. Watch who shows up and whether Zaidi signs in person. 3. **Houthi-Saudi Arabia escalation trajectory.** The Houthis broke a four-year truce with Riyadh this week [6]. Saudi Arabia knows the Houthis are coordinating with Tehran on Red Sea operations. If Riyadh responds militarily to further Houthi provocations, it reopens the Yemen war at exactly the moment Iran needs a second front to be credible. A Saudi military response, or a conspicuous absence of one, will tell you a great deal about how much risk Riyadh is actually willing to absorb to stay out of this conflict. ## References 1.
