The week of September 14-21, 2025 will be remembered as the coordinated yet divergent monetary pivot of Western central banks. The Federal Reserve initiated its rate-cutting cycle with a 25 basis point reduction, bringing the federal funds rate to a 4.00%-4.25% range, while the European Central Bank chose to keep its policy rates unchanged at 2.15%. This decision propelled US equity markets to new historic highs, with the S&P 500 and Nasdaq setting consecutive records, driven by sustained optimism in the artificial intelligence sector. Simultaneously, gold continued its march forward, crossing the psychological threshold of $3,700 per ounce and affirming its status as the ultimate safe haven amid persistent uncertainties.
Key News
1. Fed Launches Rate-Cut Cycle with Calculated Prudence¹
On September 17, the Federal Reserve announced a 25 basis point cut to its benchmark rate, the first since December 2024, setting the new range between 4.00% and 4.25%. This decision, accompanied by upwardly revised economic projections, signals anticipation of two more cuts by year-end. Committee member Stephen Miran dissented in favor of a larger 50 basis point reduction.
Analysis — The Fed’s moderation reflects a « risk management » strategy rather than an emergency response. The central bank navigates a tightrope, seeking to support a slowing economy without reigniting inflation. Internal dissent signals growing debate over the optimal pace of monetary easing.
Key Takeaway — The Fed begins prudent monetary easing, signaling confidence in economic resilience while preserving policy flexibility.
2. Wall Street Euphoria: US Indices Shatter Records²
On September 19, the S&P 500 and Nasdaq Composite closed at new historic highs for the second consecutive day, posting weekly gains of 1.1% and 1.2% respectively. The Nasdaq recorded its 26th record close of the year, driven by tech giants like Tesla (+8%) and Alphabet (+6%). Trading volumes reached their highest levels since April.
Analysis — This bullish wave demonstrates strong investor conviction in AI monetization potential. Rising volumes indicate broadened rally participation, but heavy concentration of gains among a few mega-caps maintains structural vulnerability to any sectoral disappointment.
Key Takeaway — Tech optimism and expectations of prolonged monetary accommodation propel US markets into uncharted territory.
3. ECB Opts for Strategic Pause, Maintains Rates³
At its September 11 meeting, the European Central Bank maintained its policy rates unchanged, with the deposit rate at 2.00% and refinancing rate at 2.15%. This decision comes as eurozone inflation stabilizes at 2.1% in August, and growth projections for 2025 have been revised upward to 1.2%.
Analysis — The ECB adopts a wait-and-see posture, justified by near-target inflation and a resilient economy. This caution contrasts with the Fed’s approach and could strengthen the euro against the dollar medium-term, creating a favorable rate differential.
Key Takeaway — The ECB bides its time, betting on European economic solidity while reserving the option to adjust policy based on incoming data.
4. Gold Surpasses $3,700, Confirming Ultimate Safe Haven Status⁴
Gold reached a historic peak of $3,694 per ounce on September 17 before consolidating, displaying spectacular gains of 40.5% since the beginning of the year and over 10% in September alone. This performance is fueled by falling US rates and institutional demand as a hedge against structural inflation.
Analysis — Gold’s trajectory illustrates portfolio reconfiguration in a negative real-rate environment. It’s no longer just a risk refuge, but a performance asset in a context of anticipated monetary depreciation.
Key Takeaway — Gold establishes itself as a benchmark asset in 2025, capitalizing on accommodative monetary conditions and persistent uncertainties.
5. Oil Remains Stable, Caught Between Abundant Supply and Geopolitical Risks⁵
Brent crude oil fluctuated within a narrow range between $66.63 and $68.75 per barrel. The market is torn between abundant global supply and Chinese demand concerns on one side, and supply disruptions linked to geopolitical tensions in Eastern Europe on the other. The EIA anticipates an average WTI price of $64.16 for 2025.
Analysis — The oil market exists in precarious balance. OPEC+ excess capacity limits upside potential, while geopolitical risk premiums prevent price collapse, suggesting continued volatility within a defined price range.
Key Takeaway — Oil evolves in a context of abundant supply tempered by geopolitical risks, with a neutral to slightly bearish trend.
6. Yuan Stabilizes Against Dollar Despite Weak Economic Signals⁶
The USD/CNY exchange rate remained stable around 7.11-7.14. This stability, orchestrated by Chinese authorities, masks persistent industrial activity contraction, as evidenced by the manufacturing PMI (49.4 in August). Signs of trade easing emerged with a preliminary TikTok accord.
Analysis — Yuan stability reflects policy control more than economic strength. Chinese fundamentals remain fragile, and the currency remains vulnerable to any policy changes or renewed escalation of trade tensions.
Key Takeaway — The yuan holds thanks to Beijing’s support, but economic indicators continue to raise concerns about China’s growth trajectory.
7. Bank of Japan Surprises by Beginning Balance Sheet Reduction⁷
While maintaining its policy rate at 0.5%, the Bank of Japan surprised markets on September 19 by announcing the beginning of ETF sales worth 330 billion yen annually. This decision, though modest, marks a first step toward balance sheet normalization. Two board members voted for more aggressive rate increases.
Analysis — Governor Ueda sends a very gradual normalization signal. He seeks to test market reaction without causing shock. Board division indicates intensifying pressure for faster tightening.
Key Takeaway — The BoJ discreetly begins balance sheet normalization, a historic turning point for its ultra-accommodative monetary policy.
8. Persistent UK Inflation Maintains Pressure on Bank of England⁸
UK inflation remained at 3.8% in August, well above the 2% target. Services inflation, particularly rigid, stays at 4.7%, forcing the Bank of England to maintain its policy rate at 4% at its latest meeting.
Analysis — The British situation highlights the structural nature of post-pandemic and post-Brexit inflationary pressures. The BoE is constrained to a more restrictive policy than its peers, which could support sterling medium-term.
Key Takeaway — Persistent UK inflation forces BoE caution, creating notable monetary policy divergence with the United States.
Retrospective Analysis: What Has Changed Since Our Last Report?
Our previous analysis correctly identified the imminence of Fed rate cuts and ECB’s wait-and-see posture. The euphoric market reaction validated our « end-of-cycle rally » scenario. However, we underestimated gold’s surge magnitude, which exceeded our most optimistic forecasts. Tech sector resilience, continuing to drive indices despite elevated valuations, remains the standout development, suggesting investors are projecting beyond traditional economic cycles thanks to AI promises.
Strategic Outlook & New Scenarios
Scenario Interactions
Our scenarios revolve around central banks’ ability to orchestrate a soft landing. The central scenario (45% probability) is « Controlled Monetary Divergence, » where Fed and ECB ease at different paces, creating rotation opportunities. It’s framed by two risks: « Inflation Resurgence » (30%), where easing reawakens price pressures, and « Sustained Tech Euphoria » (25%), where the AI revolution justifies current valuations and supports durable growth.
Scenario A: Controlled Monetary Divergence
The Fed pursues gradual rate cuts while the ECB waits until early 2026, creating a rate differential favorable to European assets and the euro.
- Detailed Triggers:
- Primary Threshold (Rate Spread): Fed-ECB policy rate gap exceeds 200 basis points and persists for two consecutive meetings. (Signals structural policy divergence.)
- Secondary Condition (Inflation): European inflation remains stable below 2.2% while US inflation accelerates above 3%. (Indicates divergent national inflation dynamics.)
- Macro Confirmation (Growth): Eurozone GDP growth outperforms the United States for two consecutive quarters. (Confirms benefits of European strategy.)
- Estimated Probability: 45%
- Potential Strategies: Overweight European equities (DAX, CAC 40), long EUR/USD positions targeting 1.15, gold allocation (5-8%) as residual inflation hedge.
Scenario B: Inflation Resurgence
Premature monetary easing, coupled with energy shocks, triggers inflation return above 4% in the United States, forcing the Fed to abruptly halt its cutting cycle.
- Detailed Triggers:
- Primary Threshold (Core Inflation): US core inflation crosses 3.5% for three consecutive months with sequential acceleration. (Signals return of underlying inflationary pressures.)
- Secondary Condition (Wages): Hourly wage growth exceeds 5% annualized with unemployment below 4%. (Indicates wage-price spiral.)
- Energy Confirmation (Oil): Brent price durably crosses $85 per barrel. (Confirms energy supply shock.)
- Estimated Probability: 30%
- Potential Strategies: Aggressive rotation toward commodities and real estate, gold overweighting (up to 15%), short positions on long-term bonds, focus on companies with strong « pricing power. »
Scenario C: Sustained Tech Euphoria
The AI revolution generates massive productivity gains, justifying current stock valuations and fueling a new phase of economic expansion.
- Detailed Triggers:
- Primary Threshold (AI Revenues): Tech giants’ AI-related revenues grow over 100% annualized and exceed 25% of their total revenues. (Signals massive and successful AI monetization.)
- Secondary Condition (Productivity): US non-farm productivity accelerates above 3% for two quarters. (Indicates macroeconomic productivity gains.)
- Market Confirmation (Indices): Nasdaq crosses 25,000 points with broadened market participation (over 60% of stocks rising). (Confirms healthy, no longer concentrated rally.)
- Estimated Probability: 25%
- Potential Strategies: Concentrate on tech leaders (semiconductors, cloud), exposure to promising AI startups, partial hedging via index puts to guard against rapid corrections.
Key Indicators of the Week
Indicator Summary
The week reveals a market in full transition, characterized by growing asynchrony between American and European monetary cycles. US equity indices evolve in a euphoric phase of price discovery, supported by falling long rates. This configuration favors risk assets, but complacency (low VIX) and fundamental divergences (stable oil, rising gold) suggest fragile equilibrium.
