The Guardian’s weekend overview of financial markets captures something worth sitting with: the combination of AI debt concerns, Middle East conflict, and government bond market stress has markets in a notably anxious place. The piece doesn’t add much that’s new in terms of data, but the framing reflects a shift in consensus mood from the optimism of early summer. Worth bearing in mind as positioning conversations start this week.

On the AI governance front, Trump announced what he’s calling an “AI Force” — a new institutional structure sitting alongside existing military branches — and said he would appoint a tsar to monitor for “bad” behaviour. He’s simultaneously resisted any regulatory framework, posting that the only guardrail AI needs is “a STRONG AND SMART President.” The FT separately reports that his sons have collected $620m in Pentagon loans and defence contracts tied to AI and robotics ventures over the past year, alongside a near $9bn Pentagon contract for Michael Dell. The policy and the financial interests are running in close parallel, and that’s now documented enough to be a material consideration for anyone thinking about US AI regulation risk.

The FT has a useful piece on how Big Tech is using guarantees to keep roughly $300bn of AI-related exposure off balance sheets. The structure lets tech giants’ credit strength back cheaper funding for the AI build-out without the debt appearing on their books. If you’re modelling leverage in that sector, the headline numbers are understating it.

Saudi Arabia has quietly withdrawn from the mBridge platform, the China-led cross-border payments system that Beijing has been developing as a dollar alternative. The timing matters: it comes as Riyadh is also signalling closer defence alignment with Turkey amid Houthi escalation. The Saudis are clearly keeping their options open, but pulling back from mBridge is a meaningful signal about where they think the dollar’s dominance is heading — and about their relationship with Beijing.

Ukraine launched what Russia is calling an unprecedented drone attack on the Moscow region — 450 drones downed according to Moscow’s mayor, with a major oil refinery hit. The scale is a step up and will sharpen European energy security conversations, particularly heading into the autumn heating season.

The Economist has a piece on UK house prices worth flagging: the supports that cushioned the market during the last rate cycle — fixed-rate mortgage buffers, pandemic savings — are largely exhausted. If rates stay higher for longer, the downside scenario looks more exposed than it did in 2022-23.

The ONS releases UK public sector net borrowing data for August on Tuesday morning, the first significant fiscal read since the summer recess.
