Inflation across the 20 countries that use the euro rose to 3.3% in August, up from 2.9% in July, according to Eurostat, the European Union's statistics office.
The main driver was energy. Prices in that category accelerated sharply, with the annual energy inflation rate climbing to 14.3% from 10.3% the month before. Energy costs feed into nearly everything else in an economy, from the price of manufacturing goods to heating homes and running transport, so a jump this size tends to show up broadly across the euro area's cost of living within a few months.
The release matters because the European Central Bank has an inflation target of 2%, and this reading is well above that. Traders responded by pricing in a rate increase almost as a certainty. According to data from LSEG, markets see a quarter point move higher, to 2.5%, as almost fully priced in for the ECB's upcoming September meeting. Raising rates is the traditional tool a central bank uses to cool inflation: higher borrowing costs are meant to slow spending and investment enough to bring price growth back toward target, though the tradeoff is that it also makes mortgages, business loans, and other borrowing more expensive across the euro area.
This eurozone inflation surge is not happening in isolation. It follows a similar pattern seen in the United States, where officials have also flagged sticky, energy-linked inflation this year. In both cases, higher and more volatile oil prices tied to tensions in the Middle East have been cited as a meaningful contributor, making energy costs a common thread running through central bank decisions on both sides of the Atlantic this month.
The European Central Bank's September policy decision will be closely watched, both for the size of any rate move and for what officials say about the outlook for energy prices.
Why would the ECB raise rates instead of cutting them?
Inflation is running well above the bank's 2% target, and raising rates is the standard tool central banks use to try to slow price growth.
