Eurozone Inflation Hits 4% as ECB Faces Renewed Rate Pressure

Annual inflation in the eurozone accelerated to 4.0% in October from 3.8% in September, according to preliminary data released by Eurostat on Wednesday, November 4. The increase was driven primarily by energy prices, which rose 20.8% year over year, compared with 18.9% in September.

Core inflation, excluding energy, food, alcohol and tobacco, remained unchanged at 2.5%. The ECB had kept its deposit rate at 2.50% on October 29, but the latest inflation figures have strengthened expectations of another increase in December.

Why Higher Inflation Does Not Tell the Whole Story

Energy accounts for less than one-tenth of the eurozone's consumer price index, yet its sharp increase has become a major driver of overall inflation. Excluding energy, annual price growth remained at 2.3%, unchanged from September.

This distinction matters for monetary policy. Higher interest rates can reduce borrowing and consumer spending, but they cannot directly resolve energy supply disruptions. Raising rates too aggressively could therefore weaken economic activity without immediately addressing the main source of inflation.

The economic backdrop adds to this concern. Eurozone GDP expanded by 0.4% in the third quarter, slowing from 0.6% in the previous quarter. Further increases in borrowing costs could place additional pressure on households and businesses already facing higher energy expenses.

Could Energy Costs Trigger Broader Inflation?

The main risk is that elevated energy prices gradually spread into other parts of the economy. Businesses facing higher electricity, transport and production costs may eventually pass those expenses on to customers.

Early indications remain mixed. Services inflation edged up to 3.3% from 3.2%, while unprocessed food inflation accelerated to 4.6%. However, the stability of core inflation suggests that broader price pressures have not yet intensified substantially.

Wage developments provide another important signal. The ECB's latest tracker indicates negotiated wage growth of 2.8% in the first half of 2027, compared with 2.7% in the second half of 2026. Although the figures do not establish a wage-price spiral, persistent increases could make inflation more difficult to control.

What Could Determine the ECB's Next Move?

The ECB's next monetary policy decision is scheduled for December 17, when updated economic projections should provide further insight into inflation and growth expectations.

If energy prices remain elevated and begin affecting wages and services more broadly, the case for another rate increase would strengthen. Conversely, stable underlying inflation combined with weaker economic activity could support a more cautious approach.

For investors, this distinction matters beyond the immediate interest-rate decision. Expectations of tighter policy can influence the euro, government bond yields and financing costs across the region. Higher borrowing costs could also weigh on equity valuations, particularly among companies dependent on external financing.

The central question is therefore whether the current inflation increase remains concentrated in energy or develops into more persistent price pressure. The answer will help determine how much additional tightening the European economy may need to absorb.
