The annual rate of inflation as measured by the retail price index was 2.08% in August, up from 1.81% in July, the National Statistics Office said.
The office said the 12-month moving average rate for August stood at 0.78%.
The largest upward impact on annual inflation was measured in the food index (+0.66 percentage points).
The RPI measures monthly price changes in the cost of purchasing a representative basket of consumer goods and services, and is closely linked with the cost-of-living adjustment (COLA) increases and periodic rent payment adjustments.
A closely related measure of price movements is the Harmonised Index of Consumer Prices.
