Belgium’s consumer price inflation edged down in September 2026, with the month-over-month CPI rising 0.39%, a touch below the 0.40% increase recorded in August 2026. The latest data, updated on 29 September 2026, indicate a marginal cooling in price momentum compared with the previous month.
The comparison is based on month-over-month changes: September’s 0.39% increase reflects how prices evolved from August to September, while August’s 0.40% figure measured the change from July to August. Although the difference is minimal, the easing suggests a slight moderation in short-term inflation pressure within the Belgian economy. Investors and policymakers will be watching subsequent releases to see whether this softer trend consolidates or proves temporary.
