The week in six points
Red beneath the surface, green only in pockets
Final weekly returns from the adjusted 4 September close through the Friday 11 September 2026 close. Every figure includes the full Friday session.
Four transmission chains behind the week
Observation is not causation. The key was how each event travelled through inflation, discount rates, margins and funding.
Macro & rates: markets repriced “higher for longer”
US consumer prices
August CPI rose 0.4% month on month and 3.4% year on year. Core rose 0.3% monthly and 2.4% annually.
The monthly pace was too firm for a relaxed Fed. Energy lifted the headline while services kept core pressure alive.
A sharp oil reversal or softer September data could limit the impulse.
US producer prices
Final-demand PPI rose 0.4% monthly and 5.4% annually; goods +1.1%, services +0.1%.
Cost pressure sits upstream. Companies must raise prices, sacrifice margin or deliver productivity.
Not every producer-price increase passes fully to consumers.
ECB
The ECB raised the deposit, main refinancing and marginal lending rates 25bp to 2.50%, 2.65% and 2.90%.
Energy uncertainty became monetary-policy reality. Credibility improves, but the growth risk rises.
De-escalation and falling energy costs would reduce pressure for further tightening.
US yield curve
The 10-year yield rose from 4.784% to 4.975% in the snapshot; the dollar index was nearly unchanged.
This was mainly a rates and inflation shock, not classic dollar flight. Higher real capital costs compress multiples.
The 16 September FOMC communication can reset both the level and shape of the curve.
AI & companies: strong numbers, weak shares—and vice versa
Oracle reported 30% revenue growth to $19.3bn, cloud revenue of $11.6bn (+62%), OCI of $7.4bn (+121%) and $664bn of remaining performance obligations. Yet the shares fell 1.74% Friday and 5.35% over the week: the pre-market gain gave way to concerns over gross margin, capex, financing and dilution. Qualcomm offered the mirror image. Its multi-generation work with Amazon on customised silicon and optical data-centre connectivity broadened the addressable AI market and helped the shares gain 7.84%.
| Company | Week | Assessment |
|---|---|---|
| Qualcomm | +7.84% | The Amazon collaboration opens a credible data-centre path; execution and volume still need proof. |
| Meta | +5.07% | Product catalysts and AI monetisation hopes outweighed rate pressure; capex is the counterweight. |
| Apple | +3.84% | The product cycle and pricing helped; rate sensitivity stayed below unprofitable duration names. |
| NVIDIA | −5.13% | Investors rotated toward alternative silicon paths and demanded more valuation tolerance. |
| Oracle | −5.35% | Cloud strength was not enough: margin, investment and capital needs dominated the reaction. |
| Vertiv | −8.37% | High AI-infrastructure beta works both ways; higher yields and profit-taking amplified the decline. |

Oil & geopolitics: prices reacted to physical risk, not just headlines
The weekly impulse
Brent crossed $100 on Wednesday as attacks on tankers and energy facilities intensified supply concerns. Both benchmarks rose more than 6% again on Thursday.
Friday relief
Reports of diplomatic efforts toward a temporary shipping arrangement triggered profit-taking. WTI fell 2.37%, but at $100.05 still closed 9.37% above the prior week.
The fundamental buffer
The EIA estimated that global oil inventories had fallen by roughly 400m barrels so far in 2026. Thin buffers make geopolitical outages more price-sensitive.
Equity logic
XLE +1.69% and Exxon +4.09% lagged WTI. Equities discount duration, costs, policy and demand damage—not only spot prices.
Global rotation: Korea resisted; import regions did not
United States
S&P −0.80%, Nasdaq −0.66%, Dow −1.57%, Russell −2.41%. Friday’s rebound was real relief, not a weekly breadth reversal.
Europe
DAX −1.83%, Euro Stoxx 50 −1.06%, STOXX 600 −1.66%. Dearer oil and actual ECB tightening created a double headwind.
Asia
KOSPI +3.33% benefited from chip/AI exposure; Nikkei −1.55% faced import-energy costs and BOJ tightening expectations, while Hang Seng −3.30% reflected China and global risk pressure.
Next week: three central banks, little room for error
Relief
The Fed proves less hawkish than priced, oil falls further and yields stabilise. Small caps, duration and Europe recover.
Selective base case
The Fed, BOE and BOJ deliver no major surprise. Energy stays high, AI shares trade on cash flow and funding, and indices remain volatile.
Second tightening shock
The Fed and/or BOJ turns more hawkish, oil rises again and the curve lifts discount rates. Small caps, property and richly valued infrastructure suffer.
Seven signals that matter now
- FOMC decision and projections on 16 September
- Bank of England on 17 September and Bank of Japan on 18 September
- WTI/Brent and actual tanker traffic around Hormuz and the Red Sea
- US 2Y/10Y reaction: front-end hike or long-end inflation premium?
- Russell 2000 versus S&P 500 as a funding-stress gauge
- Oracle: gross margin, capex, debt and dilution—not only RPO
- Qualcomm/NVIDIA: does rotation toward custom AI silicon persist?
