How mortgages work in Belgium

Belgium is a long-fixed market: the great majority of new lending is fixed for 20 to 25 years, and variable products carry statutory caps on how far and how fast the rate may move. That combination makes the Belgian outstanding stock one of the least rate-sensitive in the euro area, while new-business rates track the long end of the swap curve.

The rate quoted above is the ECB's MFI new-business rate for loans for house purchase in Belgium, so it reflects what borrowers are actually signing today rather than the stock of existing loans.

Implied 12-month path for Belgium

The euro area has one policy rate and one futures curve. This table applies the euro-area composite's implied 12-month change to this member's current new-business rate; it does not model a separate national pass-through.

Frequently Asked Questions

On current market pricing, no. Futures pricing implies the typical 20-Year fixed in Belgium rises from 3.70% today to 4.45% by 2027-09, about 75 basis points higher. That path assumes the European Central Bank policy rate follows the futures curve and the mortgage spread returns to its long-run average of 1.30 percentage points. It is what the market implies, not a forecast.

The typical mortgage in Belgium is the 20-Year fixed, currently 3.70% as of 2026-10-20. The European Central Bank policy rate is 2.50%, so borrowers pay a spread of 1.20 percentage points over the policy rate, covering the lender's funding cost, credit risk and margin.

About 85% of a European Central Bank policy rate change reaches the typical mortgage rate in Belgium, and it takes roughly 4 months to get there. The rest is absorbed by the lender's spread, which moves with bond yields, funding conditions and competition rather than with the policy rate itself.
