Euro zone inflation hits 4% for first time in three years as interest rate hike looms

Euro area inflation rose to 4% in October, according to a flash estimate, the first time the rate has hit or exceeded the 4% level since September 2023. The report says inflation moved up from 3.8% in September and that the increase was largely driven by energy prices. Energy inflation accelerated to 20.8% from 18.9% the previous month, keeping the region’s exposure to external energy shocks in focus.

While headline inflation is at a three-year high, the material also notes that underlying inflation and wages were “broadly stable”, despite the jump in the overall rate. Inflation remained above the ECB’s 2% target across all euro zone countries, with a spread from Lithuania’s 6.1% to Malta’s 2.3%. The release therefore frames the inflation surprise as primarily energy-led rather than a broad-based wage-price spiral.

The ECB last left its key interest rate at 2.5% after a 25 basis point hike in September. In the run-up to the print, markets were pricing a 71.8% chance of a hike at the ECB’s final meeting of the year in December; after the data release, pricing moved to more than 72%. However, the article highlights concerns that turmoil in the French bond market could constrain ECB policy, potentially limiting how aggressively it can tighten if financial fragmentation worsens.

For FX traders, the key next watch is whether euro-area inflation prints continue to confirm persistence beyond energy and whether any easing or worsening in French bond-market conditions alters the ECB’s room for manoeuvre into December.
