Parisian stocks just had their roughest week since November 2025, with the CAC 40 bleeding red for five straight sessions - a streak not seen in over a year. Despite hitting record highs earlier in the week, France's benchmark index closed down 1.23%, underperforming other European markets. We break down the economic catalysts, geopolitical tensions, and corporate earnings shaping this unusual market behavior.
How Bad Was the CAC 40's Performance Really?
The numbers tell a sobering story: five consecutive daily losses from January 8-12, 2026, culminating in a 0.65% Friday drop to 8,258.94 points. This came after Monday and Wednesday's record-breaking highs above 8,396.72 points. Compared to London's FTSE 100 (-0.12%) and Frankfurt's DAX (-0.3%), Paris clearly wore the dunce cap this week.
Stateside markets fared slightly better. The Dow Jones dipped just 0.14% to 49,375, while the Nasdaq Composite held steady at 23,530. The S&P 500's microscopic 0.04% slip to 6,941 barely registered as movement.
What Economic Indicators Moved Markets?
With few major catalysts, traders fixated on two key reports:
1.December's CPI held flat month-over-month, with annual inflation cooling to 1.8% from November's 2.3%. The harmonized EU measure showed 0.2% monthly growth (2% annually) - exactly matching analyst forecasts.
2.December saw 0.4% growth, mirroring November's revised figure. Manufacturing edged up 0.2%, while mining dropped 0.7% and utilities surged 2.6%.
"These lukewarm numbers created a 'wait-and-see' atmosphere," noted BTCC market analyst Claire Dubois. "Without clear directional signals, profit-taking after record highs became the path of least resistance."
Geopolitical Tensions: More Than Just Background Noise
Several flashpoints kept traders on edge:
- Venezuela Talks: Former President Trump reported "positive discussions" with Venezuela's interim leader, including oil market implications
- Iran Warnings: Trump threatened "very strong action" if protest executions occurred, though Tehran denied hanging plans
- Greenland Gambit: Trump's renewed interest in purchasing Greenland met with Danish "fundamental disagreement"
- Military Movements: France and allies deployed troops for reconnaissance missions and joint exercises
Oil markets reacted sharply, with Brent crude initially dropping Thursday before rebounding 0.94% to $64.47 by Friday's European close.
Corporate Earnings Season Kicks Off
Major US banks reported strong Q4 2025 results despite political uncertainty:
| Bank | Performance |
|---|---|
| JP Morgan | Beat expectations |
| Bank of America | Beat expectations |
| Wells Fargo | Beat expectations |
| Citigroup | Beat expectations |
Next week brings earnings from Netflix, Intel, and France's LVMH - likely setting the tone for January's second half.
Currency and Commodity Movements
The euro held steady at $1.604 (-0.04%) against the dollar during European trading hours. Gold prices saw modest gains as investors sought safe havens, while bitcoin traded sideways around $42,000 according to CoinMarketCap data.
Looking Ahead: Key Events to Watch
With central bank independence questions emerging after Fed Chair Powell dismissed DOJ subpoenas as "pretext," monetary policy uncertainty joins these looming factors:
- Accelerating corporate earnings releases
- Ongoing geopolitical tensions
- ECB policy meeting minutes (January 18)
- US retail sales data (January 19)

Frequently Asked Questions
Why did the CAC 40 underperform other European indices?
The CAC 40's 1.23% weekly drop reflected profit-taking after record highs, combined with France's greater exposure to global trade tensions compared to more domestically-focused UK and German markets.
How significant was the five-day losing streak?
This marked the CAC 40's longest daily losing streak since mid-November 2025 - unusual during typically bullish January markets, suggesting potential trend change.
What's the outlook for euro-dollar exchange rates?
With the euro stable at $1.604 and both central banks in holding patterns, analysts expect range-bound trading unless next week's ECB minutes or US data provide fresh catalysts.
