The Bank of England's 17 September decision is closer than the consensus admits

July's UK CPI at 2.9%, up from 2.6% in June, is mostly imported energy grinding its way through the index. The Bank has been explicit that monetary policy cannot touch global energy prices, which is true and also beside the point — the MPC's problem is second-round effects, and the August services PMI at 52.5, up from 52.1, tells you the economy is expanding just enough to make wage-setting behaviour a live question. Employment in services is still contracting. A committee looking at recovering activity, shrinking headcount and rising headline inflation has no comfortable option available to it.

The mortgage channel is where this becomes a market event rather than a policy debate. Before the Middle East conflict, markets were priced for Bank Rate cuts in 2026; they now carry the possibility of rises. A move to 4.00% on 17 September would reprice the front end of the sterling curve and, with it, the earnings assumptions embedded in Persimmon, Taylor Wimpey and Barratt — all three of which are valued on volume forecasts that assume a mortgage market getting cheaper rather than dearer. Housebuilders have spent a year priced for an easing cycle that has not arrived.

The ECB, having hiked to 2.25% in June for the first time in three years and held in July, left minutes that went out of their way to say the pause was not the end. Thursday is nearly fully priced for 2.50%.

In the US, the 162,000 August payroll print against a 53,000 consensus matters less than the revisions beneath it. June and July were both marked higher, turning a reported July decline into a gain and removing the single best piece of evidence the doves had. Against the anaemic monthly run of the preceding year, one month of 162,000 is an outlier and should be treated as such — the revisions, though, correct the whole picture the doves were leaning on. Unemployment held at 4.1%, and with hourly earnings growth reported below the 3.4% CPI rate, the median American worker is losing ground in real terms while the Fed contemplates making credit more expensive. Ten-year Treasuries touched 4.818% intra-week, the highest since November 2023. Friday's CPI is the last input before the FOMC; above 3.6% headline or 2.7% core and September hike odds cross 80%.

The FTSE 100 finished around 10,831, up roughly 0.36%, closing Friday at 10,828 and essentially unchanged on the session. The DAX fell nearly 2% to about 26,046 — the largest weekly move among the major European indices by a distance. The CAC 40 lost around 0.67% to 8,279 and the STOXX 600 slipped 0.19% to 649.88, which tells you the selling was German rather than European.

This gap has been the defining feature of European equity performance in 2026, and it is a straightforward function of index composition. London is energy, mining and defensives; Frankfurt is industry. Crude at $91 flatters the first and taxes the second. The mechanism runs through the income statement of every German chemicals, autos and capital goods business with an energy-intensive process — BASF being the obvious name, with a cost base directly exposed to feedstock and power pricing that Shell and BP earn on the other side of.

The uncomfortable part for London is that the FTSE's outperformance depends on a condition — elevated oil, elevated risk premium — that also raises the probability of a domestic rate rise. A hike on the 17th would support sterling and squeeze exactly those UK-facing consumer and property names that have been sheltering behind the index's international earnings. The FTSE has been trading as two different markets under one ticker, and a 4.00% Bank Rate would separate them.

Friday closed SPY at 770.19 (−0.24%), QQQ at 718.96 (−0.05%), DIA at 534.08 (−0.20%) and IWM at 296.01, up 0.79%. On the week the S&P added about 0.1% and the Nasdaq about 0.4% while the Dow shed 0.3%. The S&P's Friday close of 7,718.60 was down 0.38% on the session.

Small caps outperforming on a hawkish payroll print is the interesting anomaly. The obvious reading is that a strong domestic labour market supports domestic revenue, and that is probably right, but it sits awkwardly with the fact that Russell constituents are the most exposed part of the US market to higher borrowing costs. Friday's losses were concentrated in the long-duration megacaps — Apple down 2.55%, Alphabet 2.10%, Microsoft 2.05% — while Caterpillar, Honeywell and Home Depot held. That is the signature of a duration trade rather than a growth scare.

Quarter-to-date, energy is up 22% and industrials down 7%, a 29-point spread produced almost entirely by the Strait of Hormuz. Underneath, the consumer is visibly cracking: Nike, Wynn Resorts, Las Vegas Sands, VICI Properties and Carnival all printed 52-week lows on 1 September. Discretionary spending and jet fuel do not coexist happily.

The EIA's number is the one that should be pinned above every desk: 4.9 million barrels a day through Hormuz in Q2 2026, against 21.6 million before the conflict. That is not a shipping delay. Iran and the US exchanged missile strikes this week for the first time in roughly a month, Israel's defence minister threatened Iranian energy infrastructure directly, and Vice President Vance removed the diplomatic off-ramp by conditioning any talks on Tehran ceasing attacks on commercial shipping. Crude responded with its best week since mid-July.

South Korea's signalled deployment is the development most likely to be underweighted. Seoul is reviewing a logistics support vessel, maritime patrol aircraft and an EOD contribution, subject to National Assembly approval that could come this month. Korea takes 61% of its crude and 54% of its naphtha through the Strait. The naphtha figure is the one with second-order teeth: Korean crackers are a structural supplier of petrochemical feedstock into Asian and European chains, and a sustained squeeze there raises input costs for BASF, for Shell's and BP's chemicals divisions, and for every European converter buying polymer at the margin. A parliamentary vote to deploy would also tell markets that the coalition maintaining the blockade is widening — which prices the disruption as multi-year rather than multi-quarter.

The EU formally joined the US sanctions campaign this week, with Treasury Secretary Bessent signalling weekly secondary designations beginning with banks and an explicit threat to cut offending institutions out of the dollar system. Iran exposure among major European banks is thin. The mechanism is what matters — an enforcement precedent that puts correspondent banking relationships across the Gulf under a compliance regime with a capital-destroying tail. HSBC and Standard Chartered run the largest Middle Eastern networks in UK-listed banking, and their exposure is to the cost and legal risk of clearing, not to Tehran.

Defence pulled back hard over the summer on ceasefire optimism — Rheinmetall was down around 30% from its January peak by June. That correction now looks like a misread of the diplomacy. Rheinmetall is guiding 40–45% revenue growth this year to €14–14.5bn on a €80.4bn backlog, and BAE Systems sits across nuclear submarines, Typhoon and surface vessels, which is the exact procurement mix a prolonged maritime security operation generates. Hensoldt, Leonardo, Thales, RTX and L3Harris are all in the munitions-replenishment path.

Cybersecurity has stopped being discretionary.

Palo Alto's next-generation security ARR reached $9.1bn, up 63%, with remaining performance obligations of $21.2bn, up 34%, and Nikesh Arora naming agentic AI attacks as the driver. Contracted backlog of that shape means the spending survives a recession. The consequence for UK portfolios is a hole: Darktrace and Sophos are the closest domestic analogues and neither is available to public equity investors at anything approaching the scale of the US platforms. Exposure to the theme requires leaving the FTSE.

The information sector shed 23,000 jobs in August.

Computing infrastructure, data processing, hosting, broadcasting. Services account for 81% of UK gross value added, which makes Britain more exposed to AI displacement of white-collar process work than the US manufacturing base is. The names carrying that risk on the London market are the outsourcers and staffers — Capita, Serco, Hays, PageGroup — plus the content and data businesses at Pearson, RELX and Informa. Their recent underperformance has been read as cyclical. It may be the beginning of something that does not mean-revert.

BYD's export surge is a European supply chain problem.

Exports up 67.8% to 792,000 vehicles in the first half, against domestic Chinese sales down nearly 16%, with Chinese brands approaching 10% of the European market and BYD holding around 7%. The volume Volkswagen, Stellantis and Renault lose flows straight into the order books of their suppliers. Valeo and Forvia are the direct casualties; Melrose Industries and GKN carry the UK-listed version of the same demand risk through European automotive and aero programmes.

Real wages are under pressure in the United States.

Hourly earnings growth is reported below the 3.4% CPI rate — a squeeze that shows up in the 52-week low list: Nike, Carnival, the Las Vegas names. Kroger reports Friday and is the cleanest available read on trading-down behaviour, which has direct implications for Tesco, Sainsbury's and the M&S food business if the pattern crosses the Atlantic.
