FX.co ★ Belgium’s Monthly Inflation More Than Doubles in October as CPI Rises 0.91%

Belgium’s consumer price momentum accelerated sharply in October 2026, with the country’s Consumer Price Index (CPI) rising 0.91% month-over-month, more than doubling the previous month’s pace. In September 2026, the monthly increase stood at 0.39%, underscoring a notable pick-up in price pressures heading into the final quarter of the year.

The data, updated on 29 October 2026, show that October’s “Actual” figure reflects the change in prices compared with September 2026, while September’s “Previous” reading measures the change versus August 2026. The jump from 0.39% to 0.91% on a month-over-month basis signals a significant short-term acceleration in inflation dynamics within Belgium’s economy, and will likely draw attention from market participants monitoring price stability and potential policy responses.

While the figures are reported on a monthly comparison basis, the clear strengthening in CPI growth between September and October points to building inflationary pressures that could influence financial markets, wage negotiations, and cost planning for businesses and households alike.
