FX.co ★ Belgium’s June Inflation Eases to 3.40% Year-on-Year, Down from 4.08% in May

Belgium’s consumer price inflation slowed in June 2026, with the Consumer Price Index (CPI) rising 3.40% year-on-year, down from 4.08% in May 2026. The latest data, updated on 29 June 2026, signal a further easing in price pressures compared with the same month a year earlier.

Both the May and June readings are calculated on a year-over-year basis, comparing each month’s price level to that of the corresponding month in the previous year. The moderation from May’s 4.08% to June’s 3.40% suggests inflation is decelerating, which could influence expectations around household purchasing power, wage negotiations, and the policy outlook.

While still positive and indicating ongoing price increases, the drop in the annual inflation rate points to a gradual cooling in Belgium’s cost-of-living pressures as mid-2026 progresses.
