Regional Security

What we are tracking

Houthi forces fired dozens of ballistic missiles at southern Saudi Arabia on September 7 and 8, ending a four-year truce that held since 2022, according to CNN. The strikes led to the wounding of at least 73 people, including women and children, and ignited fires at energy facilities among them the Jazan City for Primary and Downstream Industries, Aramco facilities in Najran and Abha, and King Khalid Air Base in Khamis Mushait. Major General Turki al-Malki, spokesperson for the Saudi-led Brigadier General Yahya Saree said, “every aggression against our country will be met with firm response.” The escalation followed a Saudi-led coalition airstrike on a prison in Jawf that reportedly killed at least seven people, after coalition forces intercepted a flight from Tehran to Sanaa; Houthi politburo member Nasr al-Din Amer said the group would “uphold the equation of siege with siege until the aggression stops.” Brent crude rose roughly 1 percent to trade near $99 a barrel.

Why it matters

The truce that has held since 2022 was one of the few stable outcomes of the region’s prior conflict cycle, and its collapse opens a second active front for Saudi Arabia at the same time it is absorbing pressure from the Iran war. Striking a refinery of this scale inside Saudi territory, rather than harassing shipping in the Red Sea, marks a shift from maritime pressure to direct attacks on domestic energy infrastructure, and it lands as Riyadh is simultaneously negotiating the nuclear cooperation agreement below and managing its own exposure in Hormuz. The Houthis’ explicit linkage of the strikes to the Jawf prison strike and to their broader “siege with siege” framing suggests this escalation is bound to the Yemen conflict’s own logic as much as to the wider Iran war, complicating any effort to negotiate the two separately.

What to watch

Whether Aramco confirms any output impact at Jazan or nearby facilities; whether the coalition responds with further strikes inside Yemen; whether the Houthis expand targeting to Red Sea shipping or additional Saudi cities; and whether the truce’s collapse draws in renewed US or regional mediation.

Geopolitics and Security

What we are tracking

US intelligence assessments delivered to Congress describe an Iran that has grown more confident after six months of war with the United States, according to the New York Times. Briefers say Tehran believes it holds “maximum leverage” and can absorb further sanctions and military pressure. Representative Jason Crow said Iranian officials are “feeling pretty bullish about their position” and are “playing a much longer game,” while Representative Josh Gottheimer said Tehran’s government can “withstand both punishing economic sanctions and military bombardments.” Officials assess Iran’s leadership has consolidated internally, with domestic opposition largely silenced, and that Tehran retains significant missile and drone stocks despite sustained strikes. The war, which began in late February, has also seen Iranian-linked hackers target more than 100 US water systems in late July, and Meta has removed Iranian-linked social accounts running Persian-language content aimed at the US midterm electorate.

Why it matters

The assessment matters because it suggests Tehran’s calculus has shifted from enduring the war to managing it. Officials increasingly believe Iran intends to sustain the conflict through the November midterms, calculating that domestic political pressure in Washington will build faster than Iran’s own capacity to absorb strikes. Tehran’s leverage over the Strait of Hormuz, which carried roughly a fifth of global oil before the war, gives it a lever officials believe it has learned it can pull without immediately breaking. For the Gulf, this reading argues against expecting a rapid resolution and toward pricing the war as a structural condition through at least the next two months.

What to watch

Whether Iran escalates around US bases or Hormuz shipping to test its “maximum leverage” thesis ahead of the midterms; whether assessments of thinning US ammunition stocks constrain the scale of any American response; further Iranian cyber activity targeting US infrastructure; and whether growing confidence in Tehran hardens its position if negotiations resume.

Maritime Security

What we are tracking

The US Navy spent four months covertly clearing mines from the Strait of Hormuz, using SEAL divers, unmanned surface vessels and underwater robotic craft, mostly operating at night, the Financial Times reported. The International Maritime Organization estimated in June that Iran had placed roughly 80 mines across key shipping lanes. US forces have also moved to prevent new mines being laid, striking Iranian rocket launchers on Larak Island on August 30 that were reportedly preparing to deploy mines, and hitting three Iranian oil tankers on September 5, permanently disabling two and destroying one. Shipping executives believe the southern strait near Oman has now been cleared, though confidence in the wider waterway remains lower; only one mine has been sighted since, by a Pakistani survey vessel in May, and no confirmed mine strikes have occurred during the war.

Why it matters

The strait carried close to a fifth of global oil and gas before the war, and the mission is the clearest sign yet that Washington is treating a reopened strait as achievable rather than aspirational. But the operation’s secrecy points to a gap between clearance and confidence: Iranian crude loadings, which peaked near two million barrels a day before the war, recovered only to roughly 220,000 to 255,000 barrels a day in August, down from about 740,000 in July, and war-risk insurance for a typical supertanker has climbed to nearly $10 million, around ten times prewar levels. Physical clearance has not yet reset commercial risk pricing, and the mission’s own framing, that fear can be as effective as a mine, captures why.

What to watch

Whether shipowners begin routing tankers back through the cleared southern strait rather than the longer Omani corridor; whether war-risk insurance premiums begin to fall as clearance becomes public knowledge; whether Iran attempts to re-mine any cleared sections; and whether the July-to-August drop in Iranian loadings reverses or extends into September.

Nuclear and Nonproliferation

What we are tracking

The civil nuclear cooperation agreement the Trump administration transmitted to Congress on August 24 contains a pathway that could eventually let Saudi Arabia enrich uranium to 20 percent, the Wall Street Journal reported. The agreement proceeds in two stages: a two-year joint US-Saudi enrichment and conversion study, after which enrichment could begin at 5 percent, followed by a separate study on high-assay low-enriched uranium that could raise the ceiling to 20 percent. The administration also dropped the longstanding US demand that Saudi Arabia adopt the IAEA’s Additional Protocol, applying instead a narrower bilateral safeguards regime limited to “covered sites.” Two side letters detailing implementation remain classified. Crown Prince Mohammed bin Salman has allegedly said Saudi Arabia would pursue a weapon “as soon as possible” if Iran obtained one.

Why it matters 

Twenty percent enrichment sits well above what civilian power reactors require and represents, by some estimates, the majority of the technical work needed to reach weapons-grade material. Dropping the Additional Protocol narrows the IAEA’s visibility into undeclared Saudi sites at precisely the moment the kingdom is gaining a technical foundation it did not have before. The agreement sets a precedent that other US nuclear cooperation partners in the region will look to test, particularly given Riyadh’s own stated conditional posture on matching Iran.

What to watch 

Whether Congress moves to block or amend the agreement within its remaining review window; whether the two confidential side letters on implementation are made public; how the IAEA responds to the narrower bilateral safeguards regime; and whether other Gulf states seek comparable enrichment arrangements.

Capital and Technology

What we are tracking

Saudi Arabia and the UAE are pressing ahead with tens of billions of dollars in AI data centre construction despite direct attacks on the sector, Bloomberg reported. Abu Dhabi’s Khazna, backed by G42, is targeting 5 gigawatts of capacity with a first 200-megawatt phase due in the fourth quarter; Saudi Arabia’s PIF-backed Humain is targeting more than 6 gigawatts and is seeking an initial $2.5 billion raise. Amazon is expanding capacity of up to 50 megawatts in a Saudi AI zone by 2028, and Microsoft’s Saudi Arabia East cloud region is set to open in November. The build-out follows March drone strikes on three AWS facilities in the UAE and Bahrain and July satellite imagery showing damage to two further Amazon facilities in Bahrain from Iranian missile strikes. Security consultancy Integrated Security Systems estimates hardened physical security, including ballistic and blast-proof panels, is adding 5 to 7 percent to project costs. Abu Dhabi’s MGX closed a $49 billion AI-focused fund in July, and the Trump administration has loosened chip export restrictions, allowing G42 to buy advanced chips without per-transaction approval.

Why it matters 

The sector’s continuation through direct strikes signals that Gulf sovereign capital is treating AI infrastructure as a strategic commitment insulated from the war, a rare category, alongside energy exports, that neither side appears willing to interrupt further. But the binding constraint has shifted from security to regulation: analysts warn that without firm long-term commitments from Western hyperscalers and continued US regulatory alignment on chip exports, the build-out risks producing capacity without matching demand.

What to watch 

Whether further strikes target data centre infrastructure directly; how quickly Khazna and Humain reach their first-phase capacity targets; whether the Trump administration’s chip export loosening extends to Gulf operators beyond G42; and whether hyperscaler commitments keep pace with the capacity being built.

Economy and Tourism

What we are tracking

The Bahrain Grand Prix has been relocated to Malaysia for October, one of several marquee events pulled from the Gulf as the war stretches into its seventh month, the Wall Street Journal reported. Saudi Arabia’s E-Sports World Cup moved from Riyadh to Paris, April’s Saudi Formula One race was cancelled outright, and a planned Shakira concert in the UAE was dropped from the 2026 calendar. The Abu Dhabi Grand Prix remains scheduled for December, though organisers say that could change. Dubai International Airport passenger traffic fell 31 percent year-on-year in the first half of 2026 and cargo fell 29 percent. Hotel occupancy has dropped to 56 percent from roughly 80 percent in 2025, and sales of homes above $4 million fell 59 percent this spring. Wynn Resorts’ more than $5 billion casino project in the UAE has faced months-long delays and cost increases running into the hundreds of millions of dollars, though chief executive Craig Billings said the company “underwrote a country with a demonstrated ability to manage through it.” Dubai has responded with $680 million in stimulus, including fee deferrals, hotel support and discounted tourist vouchers.

Why it matters 

The reshuffled events calendar is a visible marker of a deeper shift: Gulf leaders who expected the war to wind down by summer have abandoned hope of a rebound this year and are instead planning around extended low-level conflict. The luxury segment, which depends on confidence and long lead times, is proving harder to protect than the mainstream tourism sector Dubai has propped up with stimulus, because marquee events like the Grand Prix are already committed elsewhere for the remainder of 2026.

What to watch 

Whether the Abu Dhabi Grand Prix in December proceeds as scheduled; how far hotel occupancy and luxury property sales fall before stabilising; whether further events are pulled from the calendar; and how quickly confidence in the ultra-high-net-worth segment recovers, given estimates that normalisation will take roughly six months after any resolution.
