The European Commission's consumer confidence indicator for the single-currency region dropped 4.2 percentage points to hit -20.6% as sentiment "continued its free fall since the start of the Iran war", the report said.

The wider EU consumer confidence indicator also fell 4.0pp to reach -19.4, also hitting a level not seen in 40 months.
