Consumer prices in the euro area rose 3.8 per cent in the year to September 2026, according to Eurostat's flash estimate published on 2 October, up from 3.2 per cent in August. The reading exceeded the 3.6 per cent consensus forecast, Option Finance reported, and leaves inflation almost two percentage points above the European Central Bank's 2 per cent target. Eurostat is due to publish the final September figures on 16 October.

Energy accounted for most of the acceleration. Energy prices were 18.8 per cent higher than a year earlier, up from 14.3 per cent in August, the highest annual rate of any main component, according to the Eurostat figures reported by To Vima and New Kerala. Services inflation edged up to 3.2 per cent from 3.0 per cent, and food, alcohol and tobacco rose 1.4 per cent against 1.1 per cent. Non-energy industrial goods, at 1.1 per cent, was the only major component to ease.

Underlying measures were considerably more subdued. Inflation excluding energy stood at 2.3 per cent and the measure excluding energy, food, alcohol and tobacco at 2.5 per cent, To Vima reported, a gap of well over a percentage point to the headline rate. That divergence is central to the debate at the ECB over how far monetary policy should respond to a supply-driven price shock.

The dispersion across member states was wide. Germany recorded 3.3 per cent, France 3.4 per cent, Italy 4.1 per cent and Spain 5.0 per cent, according to To Vima, with Greece jumping to 5.1 per cent from 3.7 per cent a month earlier. Lithuania, at 6.1 per cent, had the highest preliminary rate, with Bulgaria at 5.6 per cent and Cyprus and Luxembourg at 5.2 per cent.

The surge in energy costs follows the ECB's decision on 10 September to raise its deposit facility rate by 25 basis points to 2.50 per cent, its second increase of the year, according to Reuters reporting carried by Business Day. The main refinancing rate moved to 2.65 per cent and the marginal lending rate to 2.90 per cent, Admiral Markets noted. Reuters attributed the renewed pressure to military, shipping and energy attacks in the Middle East since late August, which pushed oil back above $100 a barrel and lifted European gas prices.

ECB president Christine Lagarde said after the September meeting that the outlook remained highly uncertain, with risks to the upside for inflation and to the downside for growth, and that inflation would be longer lasting than the bank had anticipated, according to Reuters. She said further increases were not obvious. The ECB's staff projections kept 2026 headline inflation at 3.0 per cent while raising the 2027 and 2028 forecasts, Newsquawk reported, and Reuters said some economists already regarded them as outdated because they predated the latest energy moves.

Market pricing has moved towards additional tightening. Reuters reported that investors expected more than three rate increases over the following 12 months after the September decision, up from two to three beforehand. Admiral Markets, citing ECB Watch data from 24 September, put the probability of a move to 2.75 per cent at the October meeting at about 60 per cent, with Goldman Sachs and UBS instead expecting the next increase in December. Commerzbank and Nordea also pointed to December, according to Reuters.

The next fixed points are Eurostat's final September data on 16 October and the ECB's Governing Council meeting on 28–29 October, with the decision due at 14:15 CET on 29 October followed by a press conference, according to Admiral Markets. The October flash inflation estimate at the end of the month and fresh staff projections at the December meeting will shape whether the bank treats the energy shock as transitory or as a reason to move policy into restrictive territory.
