Euro zone inflation hits 4%, double the ECB target, keeping a December hike likely
The rise, driven by energy as core prices held steady, matched forecasts, so markets kept pricing a roughly 72% chance of a quarter-point ECB hike on 17 December.
The short version
Written with AI, checked by an editor- Euro area inflation rose to 4.0% in October from 3.8% in September, the highest since September 2023 and twice the ECB's 2% target.
- Energy, up 20.8% on the year, supplied almost half the total, while core inflation stayed at 2.5%, so the pressure has not yet spread widely.
- The ECB decides on 17 December with new forecasts; the November inflation flash on 1 December is the next test.
Prices rise for a fourth straight month
Euro area inflation rose to 4.0% in the year to October, up from 3.8% in September, Eurostat's flash estimate showed on 4 November. That is the highest reading since September 2023 and twice the European Central Bank's 2% target. It matched what economists had expected.
This is more of a climb already under way. Inflation has risen every month since July, when it was 2.9%. Energy is the driver, pushed up by the US war in Iran in a bloc that imports most of its energy, Reuters reports. Energy prices were 20.8% higher than a year earlier, adding about 1.9 percentage points to the total. Core inflation, which strips out energy, food, alcohol and tobacco, held at 2.5%.
Countries diverged: Italy's rate rose to 5.6%, while Germany's fell to 2.8%, helped by a fuel tax cut that runs until the end of the year.
Why a steady core matters for borrowing costs
The ECB's next move depends on whether costly energy spreads into wider prices and wages. On 29 October it kept its deposit rate at 2.50% after debating a hike, and said it is "not pre-committing to a particular rate path." It also said wages showed no material response so far. October's flat core reading supports that view for now.
Because the figure matched forecasts, it gave traders nothing new, and a December hike was already priced in. The priced chance of a hike edged from 71.8% before the release to just above 72% after. Germany's 2-year yield, the one most tied to ECB expectations, rose 2 basis points (hundredths of a percentage point), while Italian and French 10-year yields fell 7 basis points, a sign that worries about heavily indebted governments eased on the day. The euro's gain against the dollar and the DAX's rise were linked to the US midterm elections, not the data.
For households, the question is the cost of credit. Many loans and mortgages follow rates linked to the ECB's, so a hike passes through to borrowers and gives savers a little more. In a Reuters poll, 64 of 73 economists expected a December hike, and a large majority in a Bloomberg survey saw the deposit rate rising to 2.75%. Borrowing has already grown dearer: the ECB said average euro area 10-year government yields rose about 35 basis points after its September forecasts were finalised.
The dates that could shift the December call
Eurostat's full October data on 18 November could revise the 4.0% flash. The ECB publishes its account of the October meeting on 26 November, and the November inflation flash follows on 1 December, where Pantheon Macroeconomics expects 4.1%. The decision comes on 17 December with new staff forecasts. A rise in core inflation above 2.5% would strengthen the case for higher rates; the end of Germany's fuel tax cut could lift its inflation in the new year.

What it means for markets
Short-dated yields track expected ECB rates, and a likely December hike keeps them anchored higher.
Wrong ifA November flash below expectations or a fall in core inflation that cuts December hike odds well below 70%.
Higher expected ECB rates support the euro, but recent moves have been driven more by US politics than euro area data.
Wrong ifA clear ECB signal against a December hike would remove the rate support.
Tighter ECB policy raises borrowing costs for indebted governments and French bond turmoil weighs on the ECB, though both yields fell 7 basis points on the day.
Wrong ifInflation peaks early in 2027 as forecast and the ECB stops after one hike.
