Spanish mortgage rates have climbed above 3% as the Euribor rises. Buyers are turning to mixed-rate loans and extending repayment to 25 years. Monthly payments remain high, but total interest costs are soaring.
Spanish homebuyers are facing a sharp change in mortgage conditions as the Euribor index, the main reference for variable-rate loans, has started September above 3%. This marks the highest level in nearly three years and is forcing both banks and clients to reconsider how they structure new home loans. The most notable shift is the growing popularity of mixed-rate mortgages, which combine a fixed interest period with a variable rate for the remaining term. This trend is a direct response to the rising cost of borrowing, as fixed-rate offers have become less attractive due to the overall increase in interest rates.
According to the latest data, new mortgages are now being signed at rates ranging from 2.85% for fixed loans to nearly 3.10% for variable ones. The average rate for all new mortgages reached 2.96% in June, the highest in a year and a half. Just four years ago, average rates hovered around 1.7%, making fixed-rate mortgages the clear favorite. Now, as the Euribor climbs, mixed-rate products are gaining ground, offering borrowers a period of stability before switching to a variable rate that tracks the market.
This shift is also reflected in the duration of new loans. Since early 2025, the average mortgage term in Spain has not dropped below 25 years. Previously, most home loans were signed for 23 to 24 years. The longer repayment period helps keep monthly payments manageable, but it comes at a cost: total interest paid over the life of the loan rises significantly. For example, a €150,000 fixed-rate mortgage at 3% TAE would generate nearly €50,000 in interest over 20 years, but more than €63,000 if stretched to 25 years.
Mixed-rate mortgages are officially classified as variable by the Spanish registry, even though they offer a fixed rate for the initial years. This nuance helps explain why variable-rate loans still account for about 40% of all new mortgages, according to the INE. However, the share of pure Euribor-linked loans is shrinking, while mixed products are increasingly favored by both banks and borrowers seeking a compromise between predictability and flexibility.
The rise in mortgage costs is not happening in isolation. It comes amid broader economic pressures and policy debates over housing affordability in Spain. As noted in a recent analysis of housing measures and political tensions, the mortgage market is just one part of a complex landscape affecting Spanish households. The current environment underscores the importance of carefully weighing loan terms, interest structures, and long-term financial commitments when purchasing property.
For context, the Euribor is the benchmark for most variable-rate mortgages in Spain and is closely tied to European Central Bank policy. When the ECB raises rates to combat inflation, the Euribor typically follows, making borrowing more expensive. The shift toward mixed-rate and longer-term mortgages reflects both the immediate impact of higher rates and the uncertainty about future market movements. Homebuyers now face a trade-off: lower monthly payments through longer terms, but a much higher total cost over the life of the loan. This dynamic is likely to remain a key issue for Spanish families and the banking sector as interest rates continue to fluctuate.
