Euro-Zone August Inflation Accelerates to 3.3%, Reinforcing ECB Rate-Hike Case

Euro-zone consumer inflation accelerated in August to its highest level in three years, strengthening the case for another European Central Bank interest-rate increase.

Data released by the European Union’s statistics office on September 1 showed the euro zone’s consumer price index rose 3.3% from a year earlier in August. That was up from 2.9% in July and marked the highest level since September 2023. The reading matched market expectations.

Core inflation, which strips out volatile items such as food and energy, slowed to 2.4%. Services inflation also eased to 3%.

Rising energy costs amid recent tensions with Iran, combined with a more resilient-than-expected euro-zone economy, have led markets to assign a higher probability to a 25-basis-point increase in the ECB’s key rate on September 10. Financial markets have already largely priced in that move.

Among member states, Italy’s inflation rate rose to 3.2% from 2.9%, while Spain’s climbed to 4.5%. Germany and France also recorded faster price growth in August.

Some ECB officials have also signaled the need for further tightening. The ECB’s deposit rate stands at 2.25%, and Chief Economist Philip Lane has previously put the upper end of the neutral-rate range at about 2.5%.

Still, the slowdown in core inflation has also fueled expectations that tightening may not proceed as quickly as markets anticipate. Analysts also say that if the energy-price shock persists, the prospect of another rate increase later this year could return to the agenda.
