What this rate is

  • The average interest rate that banks in Belgium agreed with households on new loans for house purchase in August 2026, weighted by loan volume across all initial rate fixation periods, from floating to fixed for over ten years.
  • It includes renegotiated loans and excludes fees and other charges.
  • The ECB publishes it on the 23rd working day after the month ends.
  • It is not a rate you can be offered today, not a 10-year fixed rate and not what existing borrowers pay.

Mortgage rates and the ECB

In August 2026 the ECB deposit facility rate was 2.25%; the average rate on new mortgages was 1.45 percentage points above it. The 10-year government bond yield for Belgium was 3.76% in the same month.

The ECB has since set the deposit facility rate at 2.50%, effective 16 September 2026; this figure does not yet reflect that change.

From its low of 1.43% (February 2021) to its peak of 3.90% (December 2023), the average rate on new mortgages in Belgium rose 2.47 percentage points. Over the same cycle the ECB raised its deposit facility rate from -0.50% to 4.00% (July 2022 to September 2023).

The ECB does not set mortgage rates: banks do. The ECB collects these statistics to track how its policy reaches borrowers.

In August 2026, 6.7% of new mortgage lending in Belgium was at a floating rate or fixed for up to one year; the rest was fixed for longer. Euro-area average: 16.6%. Most new loans lock in their rate for more than a year, so ECB decisions pass through more slowly, and existing fixed-rate borrowers are unaffected until their fixation period ends.
