Eurozone inflation accelerates to 3.8% in September as energy prices rise

Energy costs drive headline rate higher

Eurozone annual inflation accelerated to 3.8% in September 2026, up from 3.2% in August, according to preliminary estimates published by Eurostat on Friday. The reading is the highest inflation level in the euro area in three years and stands at nearly double the European Central Bank target of 2.0%. The print surpassed market expectations, which had projected a rate of 3.6% in a Reuters poll and 3.7% among other forecasters.

Surging energy prices formed the primary driver of the acceleration. Energy costs increased by 18.8% year on year in September, climbing from 14.3% in August in an environment of heightened geopolitical pressures tied to conflict in the Middle East and the outbreak of war in Iran. In other categories, services inflation rose to 3.2% from 3.0% in August, food, alcohol, and tobacco rose to 1.4% from 1.1%, while non-energy industrial goods eased to 1.1% from 1.2%. Core inflation, which excludes volatile food and fuel prices, edged up to 2.5% from 2.4% in August.

Disparities across member states

Price pressures varied substantially among individual eurozone members in September. Lithuania registered the highest annual inflation rate in the bloc at 6.1%, followed by Bulgaria at 5.6%, Cyprus at 5.2%, and Luxembourg at 5.2%. In Greece, inflation accelerated to 5.1% in September from 3.7% in August, driven by fuel, natural gas, and food costs. Spain recorded an annual rate of 5.0%, up from 4.6% in August and its highest figure since 2023. Belgium followed with 4.6%.

Larger economies also recorded increases in consumer prices. In Italy, inflation rose to 4.1% in September from 3.2% in August. France posted a harmonized inflation rate of 3.4%, up from 2.6% the prior month. In Germany, consumer prices rose by 3.3% year on year, reaching their highest level in nearly three years. By contrast, the lowest inflation rates across the eurozone were recorded in Malta at 2.2%, Finland at 2.6%, Latvia at 2.9%, and both Estonia and the Netherlands at 3.0%.

Policy considerations and market reaction

The September inflation data adds pressure on the European Central Bank regarding its monetary policy path. The ECB Governing Council is scheduled to meet on 28-29 October, with subsequent deliberations set for December when updated macroeconomic projections will be available. Policymakers Yannis Stournaras of Greece and Alexander Demarco of Malta, both traditionally seen as favoring looser monetary policy, stated that they do not rule out an interest rate increase at the October meeting. Economists and financial market participants predominantly expect any potential rate adjustment to occur in December.

ECB President Christine Lagarde advocated on Monday for a "measured response, as appropriate, to keep inflation under control". Lagarde noted that secondary inflationary effects remain absent and stated that the global bond market selloff would help dampen economic growth and restrain price pressures. In sovereign debt markets, the German two-year government bond yield dropped by eight basis points on Wednesday to 3.22%, while the ten-year German yield declined six basis points to 3.57%.
