FX.co ★ Belgium Inflation Edges Higher in August, Year-on-Year CPI Rises to 3.97%

Belgium’s consumer price inflation accelerated in August 2026, with the year-over-year Consumer Price Index (CPI) climbing to 3.97%, up from 3.56% in July 2026. The data, updated on 28 August 2026, indicate a renewed uptick in price pressures after a softer reading in the previous month.

Both the July and August figures are calculated on a year-over-year basis, comparing each month’s price level to the same month a year earlier. The move from 3.56% to 3.97% suggests inflationary dynamics in Belgium remain persistent and may reinforce expectations that underlying costs for households and businesses are staying elevated rather than easing.

The latest reading will be closely watched by policymakers and market participants, as the rise in annual CPI may influence views on the inflation trajectory for the remainder of 2026 and the potential stance of monetary policy in the wider euro area.
