Greece's annual EU-harmonised inflation decelerated to 11.2% in August from 11.3% in July, continuing to squeeze disposable incomes.

EU-harmonised inflation is an index of components that is used across the EU to measure inflation in a consistent way.

Natural gas prices soared 261.3% on an annual basis, while electricity prices were up 38.5% and those for heating oil up 65.1%, ELSTAT said.

The cost of housing rose 31.4% year-on-year in August while transportation prices were up 16%, with foods and non-alcoholic beverages 13.2% more expensive, the data showed.
