A $2.5trn AI shakeout, a US jobs surprise and central banks turning hawkish

Opening

Two things broke at once this week. The trade that has carried global equities for two years — anything connected to artificial intelligence — went into reverse, with a reported $2.5 trillion wiped from market values before a partial bounce. And the direction of central bank travel flipped: the Bank of England raised rates for the first time since 2023, euro area inflation hit 4%, and after a punchy US jobs report some Fed policymakers began talking about a hike. Add a Democratic sweep of Congress in the US midterms and the biggest weekly slide in oil since 2020, and you have a week in which almost every assumption got re-tested.

United States

October payrolls came in at 165,000 jobs, well above expectations, with unemployment slipping to 4.1% from 4.2% in September. That is good news for households in work, but it lands awkwardly: September CPI inflation was 4.02% year on year, up from 3.71% in August, even as core inflation (which strips out food and energy) was steadier at 2.79%. With the fed funds rate at 3.88% in October, Reuters reported policymakers weighing a rate rise, and commentary pointed the same way — Yahoo Finance called the report a new reason to hike.

Markets took it badly where it hurt most. The S&P 500 closed Friday at 7,376.86, down 2.68% on the week and 5.51% over the month; the Nasdaq Composite fell 3.37% and is down 9.79% in a month. Bonds were the odd one out: the 10-year Treasury yield was 4.85% on Monday, a little lower than a week earlier, and the gap between 10-year and 2-year yields — the "yield curve", a rough market signal on growth and rate expectations — narrowed to 0.35 percentage points on 6 November. For households, the 30-year mortgage averaged 7.18% on 5 November, barely moved from 7.24% the week before. Borrowing costs are not coming down.

Euro area

Euro area inflation reached 4% in October, the first time in three years, with a December ECB hike now widely expected from a deposit rate that has sat at 2.5%. The ECB's own wage tracker pointed to slightly higher wage growth in the first three quarters of 2027 than this year, which will not soothe hawks. For euro area employers, the message is that the cheap-money phase is over: the deposit rate is the floor under corporate borrowing costs, and government bond yields have been drifting up, with France's 10-year at 4.48% in September against Germany's 3.47%.

Britain moved first. The Bank of England lifted Bank Rate to 4%, unanimously, and said more may come, while warning inflation will near 5%. Mortgage holders rolling off fixed deals and firms with floating-rate debt will feel that directly. Oddly, European equities had a decent week — the IBEX 35 rose 3.75%, the CAC 40 1.96%, the Euro Stoxx 50 1.23% — largely because they carry far less AI exposure than Wall Street or Seoul. The FTSE 100 was flat, down 0.08%. The euro ended at $1.12.

Asia

Asia bore the brunt of the tech unwind. South Korea's KOSPI fell 14.34% over the week, with an 8% plunge that triggered a circuit breaker as chip shares tumbled; Reuters linked the slide to US midterm results feeding an AI selloff. Japan's Nikkei 225 lost 7.13%, and Taiwan, Korea and Japan were all hit hard. The contrast elsewhere was stark: Hong Kong's Hang Seng rose 4.51% and India's Sensex 7.15%, with the rupee rallying on cheaper oil and the midterm outcome.

China's price data told two stories. Consumer inflation eased to 0.7% year on year in October, below the 0.8% expected, while factory-gate prices rose 5.7%, the fastest in more than four years. Weak consumer prices with rising producer prices squeezes Chinese manufacturers' margins and, eventually, nudges up the cost of imported goods elsewhere. In Japan, the finance ministry disclosed that it spent a record ¥7.9 trillion in a single day on 30 July to support the yen — and yet the yen still sits at 157.9 to the dollar, which underscores how hard reversing a weak currency is.

Debt and politics

Democrats flipped control of Congress, and markets initially cheered — the Dow had its best post-midterm day in 44 years — before the mood soured as investors reassessed policy exposure, from AI and crypto trades to data-centre stocks, with renewables rallying. Notably, voters rejected data-centre ballot measures almost everywhere they appeared, a local-politics constraint on the AI buildout that businesses planning power-hungry projects should note. US federal debt stood at 121.19% of GDP in Q2 2026; euro area government debt was 88.8% of GDP in the same quarter.

Geopolitics was busy. Oil fell hard — Brent down 9.86% on the week to $94.44, WTI down 9.24% — as Trump signalled restraint on Iran despite fresh shipping attacks and attention turned to Iran talks, though Washington's top diplomat saw little hope of a breakthrough. A Saudi Aramco tower in Riyadh's finance district was targeted in a rare strike. Ukraine peace talks resume in Abu Dhabi, with Europe pressing the US on Ukraine and Iran at G7 talks in Paris. Elections produced no clear winner in New Zealand and a setback for the ANC in South Africa.

AI and technology

The AI complex is now the market's main macro variable. The Guardian asked openly whether the bubble is bursting after the selloff, while the big four hyperscalers are raising more than $131 billion in debt and equity for the buildout and BofA flagged the boom as a major risk to the global economy. Chip shares bounced back late in the week, and on Monday chip stocks gained even as Nvidia said it was investigating a matter involving its chief executive, which the company's CEO addressed publicly (WSJ). Reuters described the tone as a fragile calm after AI whiplash.

Company news and results

Earnings season rolled on away from the headlines. Kimberly-Clark reported third-quarter net sales of $4.1 billion in its SEC filing, down 0.4% on the prior year, with organic sales down 1.3%; adjusted gross margin of 35.5% was 130 basis points lower than a year earlier, and adjusted operating profit of $677 million was down 0.9%. Reported diluted EPS attributable to the company was $5.37 against $1.34 a year earlier, inflated by a roughly $1.4 billion pre-tax gain on a completed disposal; adjusted EPS on the same basis was $1.70, down 6.6%. The company said it completed its Kenvue transaction earlier in the week and reaffirmed its 2026 standalone outlook (filing). The detail that matters for the wider economy is in the margin commentary: unfavourable pricing net of cost inflation, offset by productivity savings — the same squeeze many consumer-facing firms describe. Elsewhere, restaurant chains are refocusing on food quality to win diners back, another sign that price rises have reached their limit with consumers.

Market mood

Nervous. The VIX at 23.42 on 9 November is up roughly 54% in a month, and CNN's Fear & Greed index reads 25 — "extreme fear" — against 44 a month ago, though slightly better than last week's 19. High-yield credit spreads, the extra yield investors demand to lend to riskier companies, widened to 3.48 percentage points on 5 November from 3.32 the previous day: a wobble, not a dislocation. Gold rose 4.17% on the week to $4,135 while bitcoin fell 7.29% and copper 3.38% — a classic defensive mix. Reddit's investing boards were dominated by chip and AI-linked tickers rather than broad index funds, which is unverified opinion but a useful gauge of where retail attention, and anxiety, is pointed. Futures pointed higher on Monday as oil fell.
