UK inflation rose to 3.1% in August, up from 2.9% in July, driven almost entirely by motor fuel prices jumping close to 24% — a direct consequence of Middle East conflict disrupting global oil supply. The number matched City forecasts, but the direction matters. The Bank of England decides on rates tomorrow, and markets are now pricing roughly a one-in-five chance of a quarter-point rise. That’s a meaningful shift from where expectations sat a fortnight ago. Services inflation will be the number to watch in the MPC’s commentary — if Bailey sounds anything like he did after the last hold, sterling could firm again.

On the AI regulatory split, the fault lines are now very clearly drawn. Jensen Huang and Mark Zuckerberg have explicitly distanced themselves from the safety-first coalition — which includes Sam Altman at OpenAI, Anthropic, and Elon Musk’s SpaceX — that has been calling for co-ordinated slowdown measures. Huang’s position is that safety is an engineering problem for individual product makers, not a regulatory one. Trump is aligned with Huang and Zuckerberg on this. The practical consequence is that any internationally co-ordinated AI governance framework looks further away than it did six months ago, which has direct implications for how UK financial firms think about AI compliance obligations and what Brussels is likely to do unilaterally.

OpenAI is separately reported to be weighing a new funding round at a $1.2 trillion valuation ahead of its IPO. That number is striking — it would make OpenAI larger by market cap than all but a handful of listed companies globally. No terms or timeline confirmed, but if the round closes near that figure it resets the benchmark for private AI valuations across the board.

The EU is backing a proposal for Canada to become an associate member, a significant step that reflects how badly the transatlantic relationship has deteriorated under Trump. For European and UK investors, the more interesting signal is what this says about the EU’s appetite to build alternative trade architecture — and whether London sees an opening or a complication in its own reset with Brussels.

Hashim Thaçi, former Kosovo president, has been convicted of war crimes and sentenced to 25 years. The verdict from the Hague-based Kosovo Specialist Chambers closes a long-running case and has some bearing on Western Balkans stability assessments, though the immediate market read-through is limited.

The Bank of England rate decision is tomorrow, Thursday 17th September.
