Netherlands mortgage rates rise amid market volatility

Mortgage rates in the Netherlands have experienced significant fluctuations and upward pressure in September 2026. One report indicates that the mortgage rate for a ten-year fixed contract with National Mortgage Guarantee (NHG) reached 4.21%, marking its highest level since late 2023. This rise is linked to capital market developments, where investors are demanding higher returns on Dutch government bonds due to inflation concerns and rising government debt.

Comparisons between lenders show substantial cost differences for consumers. According to the ACM, the gap between the cheapest and most expensive providers can amount to approximately €550 per year, potentially totaling €16,500 over a thirty-year term. While some providers offered rates as low as 3.54% for ten-year fixed NHG mortgages in mid-September, the market remains volatile, with rates shifting within days.

The rising interest rates are cooling the housing market, leading to fewer viewings, longer selling times, and a decrease in extreme overbidding. The availability of NHG typically lowers rates by 0.2 to 0.5 percentage points compared to loans without such guarantees, providing a significant cost advantage for eligible borrowers.
