Spanish homebuyers face a sharp shift in mortgage conditions as the Euribor, the basic reference for variable-rate loans, started September above 3%. That is its highest level in nearly three years, prompting banks and borrowers to reconsider how they structure new home loans. Mixed-rate mortgages, which combine an initial fixed-rate period with a variable rate for the remaining term, are gaining popularity as borrowing costs rise and fixed-rate offers become less attractive.
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, its highest level in a year and a half. 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 by giving borrowers a period of stability before they switch to a variable rate that tracks the market.
The shift is also evident in the duration of new loans. Since early 2025, the average mortgage term in Spain has not fallen below 25 years; previously, most home loans were signed for 23 to 24 years. Longer repayment periods help keep monthly payments manageable, but they increase the total interest paid over the life of the loan. 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 extended 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 helps explain why variable-rate loans still account for about 40% of all new mortgages, information from the INE. But, the share of pure Euribor-linked loans is shrinking as mixed products gain favor among banks and borrowers seeking a compromise between predictability and flexibility.
Mortgage costs are rising amid broader economic pressures and policy debates over housing affordability in Spain. A recent analysis of housing measures and political tensions noted that the mortgage market is one part of a complex field affecting Spanish households. For buyers, loan terms and interest structures shape the long-term financial commitment involved in purchasing property.
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 move toward mixed-rate and longer-term mortgages reflects the immediate impact of higher rates, along with uncertainty about future market movements. Homebuyers face a trade-off: longer terms mean lower monthly payments but a much higher total cost over the life of the loan. This is likely to remain a basic issue for Spanish families and the banking sector as interest rates continue to fluctuate.
