LONDON — Inflation across the 17 countries that use the euro fell further below target in September, official figures showed Monday, news that could encourage the European Central Bank to cut interest rates again if the recovery across the eurozone stalls.

Eurostat, the EU's statistics office, said consumer prices were up 1.1 percent in the year to September, down from the 1.3 percent rate recorded the previous month. September's rate was also the lowest since February 2010 and below expectations — the consensus in the markets was for a more modest decline to 1.2 percent.

The statistics agency said energy and food prices drove the fall in September. However, the core rate — which excludes food, alcohol and tobacco — also fell, to 1 percent from 1.1 percent, further proof that underlying price pressures are benign.
