Belgium’s consumer price inflation picked up in September 2026, with the Consumer Price Index (CPI) rising 4.69% year-over-year, compared with a 3.97% annual increase in August 2026. The data, updated on 29 September 2026, indicate a noticeable acceleration in price pressures as measured against the same month a year earlier.
On a year-over-year basis, both the current and previous readings compare each month’s price level to that of the corresponding month in the prior year. The move from 3.97% in August to 4.69% in September suggests that inflationary momentum has strengthened, potentially reinforcing concerns over the persistence of elevated prices in Belgium’s economy. Investors and policymakers will be watching upcoming releases closely to assess whether this marks the start of a renewed inflationary trend or a temporary flare-up.
