France, Spain inflation surge fully prices ECB September 25bp hike

Soaring energy costs pushed France's August inflation to 2.7 percent and Spain's to 4.5 percent, fully pricing a 25-basis-point rate hike at the European Central Bank's September meeting.

"The September hike is almost a done deal, but the path beyond September is broadly uncertain," said Paul Hollingsworth, head of developed-market economics research at BNP Paribas.

Money markets now price the deposit facility rate climbing to 2.5 percent from 2.25 percent, with another increase expected before spring 2027. The euro firmed against the dollar while eurozone bonds and equities came under pressure as traders positioned for tighter policy.

The stakes are high: a more restrictive stance beyond 2.5 percent — the level Chief Economist Philip Lane has called the upper end of neutral — would lift borrowing costs across the 20-nation bloc just as France's first-half 2026 growth data was sharply revised lower.

Energy Shock Rekindles Price Pressures

Spain's August consumer price index rose 4.5 percent from a year earlier, the fastest since 2023, while France's accelerated to 2.7 percent, the highest since May and above market forecasts. Energy was the common driver, with the source traced to the prolonged military conflict in the Middle East.

To cushion the impact of the Iran war, Spain's government approved a 5 billion euro ($5.8 billion) aid package in March that included energy tax cuts. Those measures remain in effect but have weakened since their introduction. The eurozone's 21-country inflation reading, due next week, is expected to exceed 3 percent, according to analysts.

European Commission data published Friday showed consumers' 12-month price expectations rose in August, while businesses' selling-price expectations ran above long-term averages across all sectors. That combination points to second-round effects policymakers have long feared, where higher energy costs feed into wages and broader prices.

Debate Shifts to a Restrictive Stance

Minutes from the July meeting, released Thursday, showed officials discussed whether a "moderately restrictive" policy was needed to ensure inflation returns to target — language that implies rates may need to rise above 2.5 percent. The last time the ECB signaled such a stance, it followed through with consecutive hikes within months, a pattern markets are now pricing again.

Governing Council member Martins Kazaks told Latvia's TV3 on Friday that the bank "must not let inflation take root," adding that raising rates is one way to reduce that risk. Executive Board member Isabel Schnabel told Bloomberg this week that officials must push borrowing costs higher to contain price pressures from the Iran war and from an economy growing solidly despite headwinds.

Bloomberg Economics' Ana Andrade said Spain's headline jump was driven mainly by fuel prices, with tax cuts now far weaker than at the start of the year. Core inflation eased only slightly, she noted, with sticky underlying price pressure from strong wage growth and an economy running above capacity keeping harmonized core inflation above 3 percent for the rest of the year.

The eurozone-wide inflation print next week will provide the final input for the September decision, where the debate over whether 2.5 percent is enough — or whether a restrictive stance is required — is set to dominate. If core inflation proves sticky, markets could price a second hike sooner than the spring 2027 timeline currently implied, keeping the euro bid and weighing further on the region's bonds and equities.
