The Fed's hawks are fighting a supply shock the rate tool cannot reach

The ONS confirmed on Thursday that the UK economy grew 0.4% in the second quarter, down from 0.6% in the first, with services output up 0.5% and the strength concentrated in computer programming (+3.7%) and advertising (+4.3%). Goods production went the other way — manufacturing output fell 0.5% month-on-month in June and industrial production 0.2%. That is a two-speed economy where the fast lane is narrow. The awkward part is June's 0.3% monthly print, which the ONS and independent economists attribute in part to World Cup-related spending and the heatwave. Those are one-off demand pulls. Anyone carrying Q3 forecasts built off June's momentum will be marking them down by October, which has direct consequences for Chancellor Healey's fiscal arithmetic ahead of his first Autumn Statement.

The labour market is where the UK story comes apart. Payrolled employees fell 85,000 over the year to May, the youth economic inactivity rate for those not in full-time education stands at 20.9% — on the ONS's monthly measure, the highest since the series began in 1992 — and yet headline unemployment has held steady rather than climbing toward the rise the Bank had pencilled in for year-end. Falling participation flatters that number. Against CPI at 2.6% in June and the Bank's own projection of a peak near 3.2% in the fourth quarter, the MPC's 6–3 split on 30 July is understandable and unenviable. The ECB, holding at a 2.25% deposit rate, has the easier hand.

In the US, July CPI at 3.4% with core at 2.5% was the good news; the rest of the week was not. Retail sales of $763.6bn fell 0.6%, with nonstore retailers down 2.2% — flattered downward by Amazon shifting Prime Day into June, admittedly — and motor vehicles down 1.8%. Labour-force participation slipped further, and that decline flatters the headline jobless rate.

The sequence is short and consequential: core PCE on 26 August against June's 3.3%, August payrolls on 4 September, August CPI on 11 September. If Hammack's camp wins the argument, the transmission into Britain is not gradual. A US hike lifts the front end, drags gilts with it, and pushes sterling lower — and UK mortgage pricing follows within weeks. Persimmon, Barratt Developments, and Taylor Wimpey are the cleanest expressions of that risk on the London market, because their volume assumptions are built on a mortgage market that has already absorbed one repricing and has thin capacity for another.

London's problem was mining and the pound. Antofagasta cut its 2026 copper guidance to 625,000–655,000 tonnes from 650,000–700,000 on Thursday, blaming pipeline repairs at Los Pelambres, and fell about 5%; Rio Tinto dropped 4.6% and Anglo American 2.9% alongside it. The underlying metals barely moved — copper off 0.21%, nickel 0.39%, aluminium 0.28%. What was repriced was delivery risk, and the second-order point is that a supply cut of that size lands in a market already tight, which is supportive for copper pricing into 2027 and therefore for Glencore's trading book even as Antofagasta's equity takes the immediate hit. Sterling at $1.3436–$1.3507 did the rest of the damage, mechanically shrinking the sterling value of overseas earnings across an index that mostly does not earn in sterling.

Frankfurt's outperformance is a software story. SAP, Nemetschek, Temenos, and Sage all ran between 3% and 8.5% at points during the week, and Siemens — record third-quarter orders of €27.9bn, up 14% on a comparable basis — remains the DAX's ballast. Momentum capital is choosing continental technology over London's commodity complex, and it has been doing so for long enough now that the FTSE's consolidation below its peak looks structural rather than technical.

Small caps outperforming the Nasdaq by roughly 90 basis points on a day when consumer sentiment collapsed is the market reading the data correctly — weaker demand means a lower hike probability, and nothing is more rate-sensitive than the Russell's leveraged balance sheets. The S&P 500 still posted a record close of 7,798.99 on Thursday, its 27th of the year, and a third consecutive weekly gain.

Beneath that, leadership has rotated hard. Energy was the best sector through Thursday, up nearly 6% on the week; healthcare and financials each added more than 1%. Semiconductors split violently — AMD up 6.5%, SanDisk up 7.4%, Micron up 2.3%, against Broadcom down 5.9% and Intel down 2% — while Salesforce fell 2.25% and Oracle 3.7% on Friday. High-multiple software is being sold to fund cyclicals. The VIX at 14.75 says nobody is worried about it yet — a calm that gets its first real test when Nvidia reports on 26 August.

Hormuz is the whole story, and it did not improve. Brent closed at $88.52 on Friday, up over 5% on the week, as Treasury Secretary Bessent trailed extraordinary economic measures against Iran and the naval blockade of Iranian ports held. Iran and Oman have not reached an accommodation on reopening the Strait despite earlier optimism. Washington claims some 9 million barrels a day is still transiting; tankers are doing it with transponders switched off, which tells you what the insurance market thinks. The IEA warned this week of the widest global supply deficit in five years. Houthi forces struck Saudi Arabia's Jazan refinery.

The direct beneficiaries are the obvious ones — Shell, BP, TotalEnergies, Equinor — and in London Shell and BP are the reason the index did not fall further while the miners were being sold. The more interesting exposure is on the cost side. US airline fares rose 25.5% year-on-year in the July CPI and 2.2% on the month, which is jet fuel being passed to passengers in real time. European carriers are running the same input shock through differently hedged books, so for IAG, Ryanair, Lufthansa, and Air France-KLM the live question is how much of that cost increase survives contact with short-haul price elasticity across a weakening European consumer. Maersk and Hapag-Lloyd continue to eat rerouting costs that have not yet fully appeared in European goods inflation.

There is a subtler exposure that markets are treating as free. SAP's 2026 outlook is explicitly built on the assumption of near-term de-escalation in the Middle East. SAP is also the single largest reason the DAX outperformed the FTSE 100 this week. Anyone long Frankfurt on the software rotation is therefore running an unhedged position on Hormuz reopening, whether they have framed it that way or not. On the defence side, the 5%-of-GDP commitment agreed at the 2025 Hague summit keeps BAE Systems, Rheinmetall, Leonardo, Thales, and QinetiQ underpinned regardless of how the Strait resolves — though if Healey's spending review has to absorb a 2027 growth rate of 0.3%, the UK infrastructure contractors will find out before the defence primes do.

1. The Momentum Unwind Is Further Along Than the Index Suggests

With the S&P 500 near a record, almost nobody is discussing that US momentum names have been giving back gains steadily. The rotation into energy, cyclicals, and value-tilted small caps favours Chevron and ConocoPhillips, and in London Barclays and NatWest on the value side. It hurts anything trading on an AI revenue acceleration that has not yet arrived in the numbers — Oracle and Salesforce being the week's evidence.

2. Cloudflare Has Given the Agentic AI Thesis Its First Clean Data Point

Q2 revenue of $696.1m, up 36% and more than 4.5% ahead of consensus, with large customers at 4,698 and record net additions. Machine-to-machine traffic generated by autonomous agents is a demand stream that does not correlate with consumer confidence, which is precisely what makes it valuable in a week when Michigan sentiment printed 51.0. The second-order beneficiaries are the plumbing: Arista Networks on switching, and in the UK, BT Group's infrastructure and Spirent Communications on network testing — neither of which is priced for a traffic step-change.

3. British Household Income Is Weaker Than British GDP

Youth inactivity at 20.9% — a record on the ONS's monthly measure — payroll jobs for under-25s down around 150,000 since January 2023 after minimum wage and National Insurance increases, and 85,000 fewer payrolled employees over the year. A 0.4% GDP print flattered by football and weather does not fix that. Marks & Spencer, Next, Tesco, and Whitbread are trading against a domestic income backdrop that is deteriorating beneath the aggregate data, and Hays and PageGroup — whose net fee income tracks placement volumes directly — are the purest read on whether hiring intentions recover.

4. Oxford BioMedica's 20% Fall Is a Sector Signal

Guidance cut to £180–200m on client programme deferrals, delayed timelines, and a change in one major customer's procurement strategy, with the Durham, North Carolina facility ramping slowly. After years of capacity buildout, the cell and gene therapy CDMOs are discovering that customer concentration cuts both ways. The Durham commentary reads straight across to Lonza's contract book.
