Spanish Mortgage Rate Types Explained: Fixed, Variable and Mixed Mortgages, the Euribor and How to Choose (2026)

Spanish mortgages come in three rate types: fixed, variable and mixed. The fixed rate locks the interest for the full term, the variable rate tracks the 12-month Euribor plus a bank spread, and the mixed rate fixes for an initial period then switches to variable. The 12-month Euribor stood at 2.804% in May 2026 per the Banco de Espana official reference table, so a variable mortgage at Euribor plus 1.5% would charge roughly 4.3% at review. Choosing between the three depends on how much rate certainty you need, how long you plan to hold the property, and where you expect the Euribor to go.

What are the three Spanish mortgage rate types?

Spanish law and banking practice recognise three mortgage rate structures, each with a distinct risk profile. The Banco de Espana’s client guide defines them as follows: a fixed-rate mortgage sets one interest rate and one monthly instalment for the entire loan term; a variable-rate mortgage sets the rate as a benchmark plus a spread, reviewed every six months or annually; and a mixed-rate mortgage fixes the rate for an initial period then applies a variable rate for the remainder.

The legal framework for all three is Ley 5/2019, de 15 de marzo, reguladora de los contratos de credito inmobiliario (BOE-A-2019-3814), which took effect on 16 June 2019. The law governs transparency, early repayment fees, cost allocation and the prohibition of floor clauses on new variable mortgages. The deeper provisions of that law, including the notary transparency appointment and the cost allocation split, are covered in the Spanish mortgage law guide. This page focuses on the rate types themselves and how to choose between them.

How does a fixed-rate mortgage work in Spain?

A fixed-rate mortgage (hipoteca fija) locks the interest rate and the monthly instalment for the entire loan term, so the borrower knows the total cost of the loan from day one. The Banco de Espana notes that fixed rates are usually set higher than variable starting rates, and the repayment period is typically shorter, around 20 years rather than the 20 to 30 years common on variable loans.

The advantage is certainty. The borrower is insulated from Euribor movements, and the instalment never changes. The disadvantage is the price: because the bank takes the interest rate risk for the full term, it charges a premium. If rates fall, the borrower is locked in and must pay the early repayment fee to refinance. The maximum early repayment fee on a fixed mortgage under Ley 5/2019 is 2% of the repaid capital in the first 10 years and 1.5% thereafter, a cap that did not exist before the 2019 reform.

How does a variable-rate mortgage work in Spain?

A variable-rate mortgage (hipoteca variable) sets the interest rate as a reference benchmark plus a constant spread. The Banco de Espana confirms the standard structure: the rate is expressed as the sum of a benchmark, typically the 12-month Euribor, and a fixed percentage, such as Euribor plus 2.1%. The rate is reviewed every six months or annually, and the instalment is recalculated at each review based on the outstanding capital, the remaining term and the prevailing Euribor value.

The 12-month Euribor is the dominant reference for Spanish variable mortgages. The Banco de Espana publishes the official monthly value in the BOE, and the table of official mortgage market reference rates is the authoritative source. In May 2026 the 12-month Euribor stood at 2.804%, up from 2.747% in April and 2.565% in March. A variable mortgage at Euribor plus 1.5% would therefore charge 4.304% at a review using the May 2026 value.

Since Ley 5/2019 took effect on 16 June 2019, new variable mortgages cannot include a floor clause (clausula suelo) that sets a minimum rate. The Banco de Espana confirms that the law prohibits downward limits on variable rates, so the rate can fall without restriction when the Euribor drops. The interest cannot go negative. For more on the floor clause history and the Supreme Court and CJEU rulings that led to the ban, see the mortgage law guide.

What is a mixed mortgage and who is it for?

A mixed mortgage (hipoteca mixta) applies a fixed interest rate for an initial period, typically 3 to 10 years, then switches to a variable rate referenced to the Euribor for the remainder of the term. The Banco de Espana describes it as a hybrid: the borrower gets instalment certainty during the fixed phase, then assumes rate risk in the variable phase.

The mixed structure suits borrowers who want stability in the early years but expect to sell, refinance or benefit from lower rates later. The fixed period is usually priced between the full-term fixed rate and the variable starting rate, so the borrower pays a smaller premium for certainty over a shorter window. When the fixed period ends, the rate converts to the 12-month Euribor plus the contractually agreed spread, reviewed on the same six-monthly or annual cycle as a standard variable mortgage.

The early repayment rules for the fixed phase follow the fixed-rate caps (2% in the first 10 years, 1.5% thereafter), while the variable phase follows the variable caps (0.25% or 0.15% in the first three years). A borrower who plans to repay early during the fixed phase should factor the 2% cap into the decision.

How do the three rate types compare?

The table below compares fixed, variable and mixed mortgages across six dimensions that matter for a Spanish property buyer in 2026.

Dimension	Fixed	Variable	Mixed
Reference rate	None (rate is set)	12-month Euribor plus spread	Fixed rate initially, then Euribor plus spread
Typical 2026 rate	Higher than variable starting rate	Euribor plus spread (Euribor 2.804% in May 2026)	Between fixed and variable for the initial period
Rate-change frequency	Never	Every 6 or 12 months	Fixed for 3 to 10 years, then every 6 or 12 months
Instalment certainty	Full term	None (rises or falls with Euribor)	Initial period only
Early repayment cap (Ley 5/2019)	2% first 10 years, 1.5% after	0.25% or 0.15% first 3 years	Fixed phase: 2% / 1.5%. Variable phase: 0.25% or 0.15%
Best for	Hold-to-maturity borrowers who want total certainty	Borrowers who expect rates to fall or stay low	Borrowers who want early stability but plan to reassess

What is the Euribor and how does it drive variable rates?

The Euribor (Euro Interbank Offered Rate) is the rate at which European banks lend to each other in the interbank market, published daily by the European Money Markets Institute. The 12-month Euribor is the standard reference for Spanish variable mortgages because it reflects the cost of one-year bank funding, which is the closest match to a mortgage rate reviewed annually.

The Banco de Espana publishes the official 12-month Euribor value each month in the BOE via a resolution, and the value is recorded in the table of official mortgage market reference rates. The May 2026 value of 2.804% was published in BOE-A-2026-11844. The series shows a clear upward trend in early 2026: 2.245% in January, 2.221% in February, 2.565% in March, 2.747% in April and 2.804% in May. The average rate on mortgage loans for over three years for house purchase across all credit institutions, also published by the Banco de Espana, was 2.986% in May 2026.

A variable mortgage rate is always expressed as Euribor plus a spread. If the contract specifies Euribor plus 1.5% and the review month’s Euribor is 2.804%, the rate for the next period is 4.304%. If the Euribor falls to 2.0% at the next review, the rate drops to 3.5%. The spread is fixed for the life of the loan; only the Euribor component moves.

How do you choose between fixed, variable and mixed in 2026?

The choice depends on three factors: your risk tolerance, your time horizon and your view on the Euribor trajectory.

If you plan to hold the property for the full mortgage term and want to know the total cost to the cent, a fixed rate is the clean answer. You pay a premium for that certainty, and refinancing if rates fall costs up to 2% of the repaid capital in the first decade. The non-resident mortgage guide covers the borrowing capacity and LTV bands that determine whether a fixed rate is affordable.

If you expect the Euribor to stabilise or fall from its current level, a variable rate lets you start lower and benefit from any decline. The risk is that the Euribor continues to rise, as it did through the first five months of 2026, and the instalment increases at each review. The early repayment fee is much lower (0.25% or 0.15% in the first three years), so you can exit cheaply if the rate path turns against you.

If you want certainty for a defined early period but expect to sell or refinance before the end of the term, a mixed mortgage splits the difference. The fixed phase gives you a predictable instalment while you settle in, and the variable phase lets you benefit if rates ease. The mortgage subrogation guide explains how to switch lenders or rate type if the variable phase becomes uncompetitive. The early repayment fee rules for both phases are detailed in the early repayment guide.

What should you check before signing?

Five checks matter regardless of which rate type you choose.

First, read the FEIN (Standardised European Information Sheet). The bank must deliver it at least 10 natural days before you are bound. It states the rate type, the spread, the reference rate, the instalment, the total cost and the early repayment conditions.

Second, confirm there is no floor clause. On any new variable mortgage signed after 16 June 2019, floor clauses are banned. On a mixed mortgage, check the variable phase terms for any floor or cap language.

Third, check the early repayment fee structure. For variable loans, confirm whether the bank applies the 0.25% option or the 0.15% option in the first three years. For fixed loans, confirm the 2% / 1.5% cap. For mixed loans, confirm which cap applies in each phase.

Fourth, check the rate review frequency. A six-monthly review means the instalment adjusts twice a year; an annual review means once. More frequent reviews mean faster exposure to Euribor movements but also faster benefit if rates fall.

Fifth, check the spread. The spread is the one number that stays with you for the life of a variable or mixed mortgage. A 0.5% difference in the spread on a EUR 400,000 mortgage over 25 years is roughly EUR 30,000 in total interest. Negotiate it before signing, not after.
