Eurostat's September flash estimate put euro-area annual inflation at 3.8%, up from 3.2% in August. The energy component reached an estimated 18.8% annual rate.
What is known.
Eurostat scheduled its next flash estimate, covering October, for 4 November. That release is the specified test of whether headline inflation remains above 3.5%.
Why it is a possibility.
The latest reading is 0.3 percentage points above the threshold, and energy was accelerating into September. That gives persistence into October a modest edge over a drop below 3.5%.
Energy prices can change quickly, and the September number was a flash estimate. Easing energy or other prices could pull the October headline below the line.
What could prevent it.
One month's energy move can reverse quickly. October's flash estimate could fall below the threshold if energy prices ease or other components soften.
How it will be assessed.
Resolves yes if Eurostat's October 2026 euro-area annual HICP flash estimate is greater than 3.5%, using the release scheduled for 4 November 2026.
