The Fed hikes, oil jumps, and the cost of money rises everywhere

The week in one paragraph

Two things collided this week. A drone attack knocked out Saudi Arabia's East-West pipeline, the route that lets the kingdom ship crude without passing the Strait of Hormuz, pushing WTI to $101.98 and Brent to $105.62 by Wednesday's close — up 6.2% and 4.4% on the week. And the world's biggest central bank responded to stubborn inflation by doing something it has not done since 2023: raising interest rates. The Federal Reserve lifted its policy rate by a quarter point and signalled one more increase this year. Equities slipped worldwide — the S&P 500 fell 1.1% on the week, the KOSPI 4.7% — the dollar rose 1.6%, and the US 10-year Treasury yield closed at 5.01%. For households and firms, the message is blunt: energy is dearer and borrowing is not getting cheaper.

United States

The Fed's move was well flagged — economists had been predicting it — but the framing still jolted markets. Chair Kevin Warsh said plainly that "inflation is too high", and the Dow fell around 700 points as he spoke. CNBC's read was that the hike reinforced the Fed's independence after political pressure.

The data gave him cover. August CPI inflation was 3.71% year on year, up from 3.54% in July, though core inflation — which strips out food and energy — eased slightly to 2.76%. Unemployment held at 4.1%. And consumers kept spending: retail sales rose 1.2% in August, which Reuters described as underscoring the economy's resilience while inflation pressures build. Separately, Axios reported that Americans' incomes hit a record while lower earners lost ground — a reminder that averages hide a lot.

The cost of this is visible in borrowing. The 30-year mortgage rate averaged 6.76% in the week to 10 September, up from 6.71%. The gap between 10-year and 2-year Treasury yields — the "yield curve", a rough gauge of how the market sees growth and rates ahead — narrowed to 0.27 percentage points from 0.33 the day before, meaning long rates and short rates are converging again. Diesel is the other squeeze: Bloomberg reported record diesel prices, which feed straight into freight, food and construction costs.

Euro area

The ECB got there first. On 10 September it raised its deposit rate by a quarter point to 2.50%, its second hike of 2026, with coverage attributing the move to persistent energy-driven inflation and the ECB simultaneously raising both its inflation and growth forecasts. Euro area HICP inflation was 2.93% in July on the latest Eurostat reading; one report of the ECB decision put the more recent figure at 3.3%. Growth has picked up — euro area GDP was 1.16% higher than a year earlier in the second quarter, against 0.54% in the first — and unemployment is steady at 6.4%.

The euro fell 1.5% against the dollar to $1.15. European equities were softer but calmer than Asia: the Euro Stoxx 50 lost 0.7%, the DAX 0.15%, the FTSE 100 edged up 0.2%. In Britain, inflation climbed to 3.1% just before a Bank of England meeting at which it was expected to hold rates and slow the pace of its bond sales, even as some banks now expect UK hikes.

Asia

The Bank of Japan was set to raise rates to a 31-year high, with the Japan Times calling it the hardest test in a generation. The yen nonetheless weakened 1.7% to 156.19 per dollar, and Japan's 10-year government bond yield was 2.94% in August, up from 2.79% in July — a big deal for a country whose government debt was close to 240% of GDP in the IMF's 2023 estimate. The Nikkei fell 2.7% on the week and is down 8.3% over a month.

China's August figures were lopsided. Retail sales rose just 0.4% and industrial production 5.2%, with investment slumping further and the tech boom powering factories while consumption slows. That imbalance — strong supply, weak domestic demand — keeps Chinese exports cheap for the rest of the world and keeps pressure on Beijing for stimulus. India's inflation rose to 4.82% in August from 4.45%, which economists said raises the odds of a rate rise in October. The Sensex fell 2.8% and Hang Seng 2.6% on the week.

Debt and politics

Higher long-term yields are a fiscal problem as much as a market one. US federal debt was 122.6% of GDP at the start of 2026 and the deficit was 5.77% of GDP in 2025. In Europe, government debt reached 88.9% of euro area GDP in the first quarter, up from 87.7%. France's prime minister said bluntly that "we can no longer finance everything" as the government hunts for spending cuts, with debt interest costs rising as yields approach 2008 highs; French 10-year yields averaged 4.00% in August, a full 0.8 points above Germany's 3.18%. In Sweden, the centre-left opposition won the election. Brussels was busy too: Commission President von der Leyen floated Canada becoming the bloc's first associate member and proposed an EU-wide social media ban for under-13s. In Washington, the Senate blocked a crypto bill, knocking bitcoin lower, while the Ways and Means committee approved a crypto tax bill on a bipartisan vote.

AI and technology

The money kept getting bigger even as the mood got twitchier. OpenAI is reportedly weighing a funding round at a valuation above $1.2 trillion, with Fortune reporting that an IPO looks unlikely and venture funding is the route instead; it also agreed to buy a startup developing a smartphone camera. Dealroom counted Nvidia's $13bn deal anchoring a $78bn week of M&A. Infrastructure politics is arriving with the capital: New York proposed $1m per megawatt in community investment from data centres, a sign that the electricity and land costs of AI are becoming a local bargaining chip. Meanwhile Mark Zuckerberg and Jensen Huang pushed back on talk of an AI slowdown, the FT reported that safety pushes by AI bosses have opened rifts inside OpenAI and Anthropic, Sam Altman said people are right to fear advancing AI but should trust its leaders, and a major Democratic donor warned that time is running out to stop Americans hating AI. Why it matters: AI capital spending is now a visible chunk of growth, energy demand and corporate borrowing, so the politics of power bills and public consent could shape the macro path as much as the technology does.

Company news and results

Oracle reported first-quarter fiscal 2027 results on 10 September: company-reported total revenues of $19.3bn, up 30%, cloud revenue up 62% to $11.6bn, and remaining performance obligations — contracted work not yet delivered — of $664bn, up $209bn from a year earlier. It also disclosed negative free cash flow of $5bn for the quarter as it builds data centres, and the sale of $20bn of stock through an at-the-market programme. That is the AI build-out in one filing: enormous booked demand, funded up front. Lennar's third quarter, reported Wednesday, shows the other side of higher rates: company-reported new orders down 9%, deliveries down 3%, revenues of $8.0bn and earnings of $1.19 a share against $2.29 a year earlier, with management noting the 30-year mortgage rate at about 6.8% at quarter end and trimming full-year deliveries to 80,000–81,000 homes from 82,000–83,000.

Consumer and freight results told a consistent story. Kroger's second quarter showed company-reported identical sales excluding fuel up 0.2% against 3.4% a year earlier, adjusted EPS of $1.09, and full-year identical-sales guidance cut to 0.2%–0.8% from 1.0%–2.0%, while profit guidance was reaffirmed. In transport, J.B. Hunt warned third-quarter earnings would fall; in aviation, Boeing's chief executive said 737 Max production is taking longer than expected to stabilise and American Airlines said 30% of seats now drive half its revenue — premium demand holding up while the middle thins out. On deals, state attorneys general sued to block the Warner Bros.–Paramount merger and the Justice Department sought more information on a $22bn Roku deal.

Market mood

Fear is creeping back. The VIX closed at 17.71, up roughly 7.6% on the week; CNN's Fear & Greed index sits at 26 ("fear") against 38 a week ago and 64 a month ago. Credit markets are only mildly worried: the high-yield spread — the extra interest riskier companies pay over the government — was 2.76 percentage points on 15 September, up from 2.71 the day before, which is a nudge, not a rupture. Small caps took the brunt, with the Russell 2000 down 2.1% on the week and 6.5% on the month. Gold fell 3.5% and copper 5.3%. Retail investors on Reddit were focused on the Saudi pipeline, record diesel prices, the 10-year hitting 5% and the Fed meeting itself; attention in the most-mentioned tickers was split between broad index funds and memory-chip and AI names, which suggests the AI trade is still where the risk appetite lives.

What to watch next week

Central banks again: the Bank of England and the Bank of Japan both decide, and Japan's August national CPI lands. Euro area flash PMIs will show whether the energy shock is denting activity, and US jobless claims and housing data will test how much the rate rise bites. Above all, watch the repair timetable for the Saudi pipeline: Riyadh has already cancelled some cargoes, and how long the outage lasts will do more to set petrol, diesel and airfare prices this autumn than anything a central bank says.

On the calendar next week

• →Bank of England rate decision and guidance on the pace of bond sales (quantitative tightening)
• →Bank of Japan policy decision and Governor's press conference
• →Japan's August national CPI
• →Euro area flash September purchasing managers' surveys
