The big story overnight is the US-Iran escalation. American forces have now completed a third round of strikes on Iran, and Tehran has closed the Strait of Hormuz in response. The IRGC is vowing a “crushing response” to any further attacks. Missiles and drones were fired at Gulf states following the overnight strikes, with shrapnel injuring three people in Qatar and incidents reported in the UAE, Kuwait, Bahrain, Oman and Jordan. The trigger for the latest US strikes was an attack on a Cyprus-flagged vessel in the Hormuz waterway. If the closure holds, you’re looking at roughly 20% of global oil supply disrupted at the chokepoint. Energy positioning and shipping exposure will be front of mind when markets open Monday.

Lindsey Graham, the South Carolina Republican senator and one of the most hawkish voices in US foreign policy, has died aged 71 following what his office described as a brief and sudden illness. He had been in Kyiv meeting Zelensky on Friday. His death removes a significant institutional advocate for Ukraine funding and for a harder line on Iran at a moment when both issues are live. The Senate arithmetic on any authorisation or appropriations votes shifts with him gone.

China’s financial regulators are pressuring credit rating agencies to pull back on triple-A designations for higher-interest corporate borrowers. The move is a direct attempt to compress the spread between ratings and actual credit risk in the onshore bond market, which has long been criticised for ratings inflation. For anyone with exposure to Chinese corporate debt, the practical effect is a forced repricing of risk that the market has been undervaluing.

The EU is signalling it will use fines as a lever against big tech platforms on consumer protection, with Justice Commissioner Michael McGrath saying Brussels wants to strengthen social media safeguards. This follows the existing DMA and DSA enforcement architecture but suggests the Commission is willing to escalate on a separate track. Worth watching alongside the ongoing US-EU trade negotiation backdrop.

On the AI side, OpenAI is moving to build out dedicated product lines for families and older adults, with a job posting for a product manager focused on households and caregivers. It’s a small signal but consistent with a push to broaden the paying subscriber base beyond professional and enterprise users ahead of any IPO-related scrutiny of growth metrics.

The UK’s healthy life expectancy is falling, with reporting suggesting NHS structural issues are a contributing factor rather than just lifestyle trends. No immediate policy trigger, but it feeds directly into the fiscal debate around health spending ahead of the autumn spending review.

Monday brings no single scheduled data release of the first order, but European energy markets will open with the Hormuz closure as the dominant pricing input. Watch Brent at the open.
