Paris risk and the ECB's real rate, not spreads, squeeze the euro

What the currency did, and what the spread did

Trading Economics data show the euro falling 0.67% against the dollar on 11 November to close at 1.1089. That is its weakest level since March 2025; the currency has lost 4.35% over a year and 0.60% over the past month. The same day the dollar index rose 0.67% to 102.92, according to the Capp Notes close.

The market's ready explanation is the Fed. After hot October inflation data on 10 November, fed funds futures fully priced a December hike, and Fed Governor Waller said he would back 50 basis points if the data ran hot. The yield spread does not carry this story. The US 10-year yield was 4.99% on 10 November and Germany's 3.31% on 11 November, a gap of about 168 basis points.

Using Trading Economics' monthly change data, the US yield stood at about 5.24% a month earlier and the German yield at about 3.48%. The gap therefore narrowed from about 176 to 168 basis points, a move of 8 basis points. The spread turned in the euro's favour while the euro fell 0.60%, which shows another constraint is holding the currency back. The US bond market was closed on 11 November for a holiday, so the two readings come from different days.

First constraint: the Paris risk premium

France's 10-year yield reached 4.80% on 11 November, up 1.42 points over a year. Against Germany's 3.31%, the gap is about 149 basis points. In Talay's 1 October report it was in a 111–120 basis-point range; in six weeks it has widened by roughly 30–38 basis points.

This widening of more than 30 basis points came while yields were falling, so it went largely unnoticed. The French yield fell 0.11 points over the month and the German yield 0.17 points. Both fell, but Bunds fell 6 basis points faster; readers saw relief in the headlines while the spread quietly grew. In its 11 November note, Trading Economics listed France's political and fiscal troubles among the pressures on the euro.

French inflation was 3.4% in October and unemployment 8.2% in September. The National Assembly's rejection of the revenue side of the 2027 budget, noted in an earlier Talay entry, shows that a fiscal anchor is not yet in place. As the spread on the euro area's second-largest economy widens to 149 basis points, foreign investors are pricing in currency risk as well.

Second constraint: the ECB behind inflation

According to Eurostat's flash estimate, euro area inflation rose from 3.8% to 4.0% in October. Energy inflation is 20.8%, services 3.3% and the core rate 2.5%. The ECB's deposit rate is 2.50% and its main refinancing rate 2.65%. The last hike came on 10 September, and rates were held on 29 October.

The real rate, the policy rate minus inflation, is about −1.5 points against the headline figure and zero against the 2.5% core. The ECB believes it can be patient by looking at 2.5% core inflation; the currency looks at 4.0% headline and the energy bill. Because the euro area imports most of its energy in dollars, every fall in the currency opens a separate channel feeding 20.8% energy inflation.

ECB chief economist Lane said on 11 November that another hike might be needed in December. On 9 November LSEG data showed the market assigning a 66% probability to a December hike, with one move fully priced by February. A 25-basis-point rise in the deposit rate only lifts the headline real rate to −1.25 points, while the Fed is moving up from 4.00% over the same period.

Third constraint: guidance weakens as the chair empties

Lagarde will step down by 7 February 2027, and two candidates, Klaas Knot and Pablo Hernández de Cos, applied to the Eurogroup on 6 November. With the presidency in transition mode until 7 February, forward guidance carries less weight. On 11 November Trading Economics listed this uncertainty among the pressures on the euro.

On the German curve, the 2-year Bund yields 3.12%, the 10-year 3.31% and the 30-year 3.67%; the 30-year has fallen 0.17 points in a month. The 10s-2s spread is only 19 basis points: the front end prices hikes while the back end carries growth worries. What would lift the euro back above 1.11 is not higher policy rates but a fiscal anchor in Paris and an ECB path that catches up with 4.0% inflation.
