Core prices matched expectations, pointing to energy as the main source of the surprise. At the same time, the gap between French and German yields widened to about 1.5 percentage points.

The European Central Bank received two signals on Friday that point in different directions.
Consumer prices in the euro area rose 3.8% from a year earlier in September, according to the flash estimate, above the 3.6% economists expected. Prices rose 0.6% from August. Core inflation, which strips out energy, food, alcohol and tobacco, rose to 2.5% from 2.4%, in line with forecasts.
A headline beat with core on target places the surprise in energy, the same driver lifting inflation on the other side of the Atlantic. Core still edged up a tenth of a point, so the reading does not rule out broader price pressure, but the bulk of the overshoot sits outside it.
The bond market's message
In the bond market, French debt sold off again. The spread between French and German 10-year yields widened to about 1.5 percentage points, its widest since the euro-area debt crisis, according to Trading Economics data. France's 10-year yield briefly rose above 5%, its highest since July 2002.
The supply behind it
France's debt agency, Agence France Trésor, plans a record €340 billion of medium- and long-term bond issuance in 2027, up from €310 billion this year. It projects the state's debt charge at €72.9 billion next year, on an assumed 10-year rate of 4.3%. The government targets a deficit of 5.0% of output in 2027, after a forecast 5.4% this year. France's public-finance watchdog has described the government's growth forecast as optimistic.
The rate assumption is now well below the market. If the 10-year stays near 5%, new 10-year debt will be priced about 0.7 percentage point above the level the debt agency built into its interest bill.
The ECB's position
The two signals collide at the central bank. Headline inflation of 3.8% is the sort of reading that has kept the ECB raising rates. Widening spreads in a member state tighten financial conditions on their own, doing some of the central bank's work in the economies under pressure.
Bundesbank President Joachim Nagel said this week that the ECB focuses on inflation, not spreads. The euro was little changed against the dollar on Friday, near $1.1257.
Competing views
One reading is that a fiscal and political premium is repricing France toward the euro area's periphery. A 2027 budget, record issuance and a presidential election that year all sit behind the widening, and Italy and Belgium are exposed to contagion.
A second reading is that the move is orderly and tied to a global sell-off in long-dated debt. Auctions are still clearing, U.S. and British long yields are near multi-decade highs as well, and a core reading in line with forecasts gives the ECB room to wait.
Dates ahead
The final September inflation reading is due Oct. 16. Britain presents its budget on Oct. 28, and the ECB's next decisions follow. The French-German spread is the observable that separates the two readings: a move back toward 1.3 points while German yields stay high would point to a global move, and a hold above 1.5 would point to a premium specific to France.
