How to negotiate your mortgage with falling Euribor in 2026
With Euribor at two-year lows, many mortgage holders can improve their terms. Practical guide to negotiating with your bank: novation, subrogation, and switching to fixed rate.
Source: Bank of Spain, official reference rate data.
Key takeaways
With Euribor below 2.5%, a variable mortgage of 200,000€ over 25 years can save more than 200€ per month compared to the 2023 peak.
- Novation (renegotiation with your own bank) is the fastest and most affordable way to improve the spread or switch to a fixed rate.
- Subrogation (changing banks) can achieve better terms but involves notary and agency fees that need to be calculated.
- Before negotiating, calculate the real cost of the change with the mortgage simulator: it is not always profitable even if the rate drops.
Why now is the time to review your mortgage
The 12-month Euribor — the reference index for most variable mortgages in Spain — has fallen significantly from its peak of 4.16% in October 2023. In June 2026 it trades around 2.3%, meaning downward revisions for millions of mortgage holders.
However, if your variable mortgage has a high spread (for example, Euribor + 1.2% or more), you may be able to negotiate better terms with your bank or switch to one offering more competitive spreads.
Quick tips
- Check in your mortgage deed what your current spread is and when the next annual or semi-annual review takes place.
Novation: negotiating with your bank without changing lender
Novation is the modification of your mortgage terms agreed with the same bank. You can request a reduction of the spread, switch from variable to fixed rate, extend the term, or change the amortization system. Its cost is lower than subrogation: mainly notary fees (between 300€ and 1,000€ depending on the case) and, in some banks, a novation fee.
To have negotiating power, arrive with offers from other banks in hand. Your bank will prefer to improve terms rather than lose a solvent customer. Do not accept the first proposal and always ask for the binding offer in writing.
Subrogation: switching banks for better terms
If your bank does not improve the offer, subrogation allows you to take your mortgage to another bank with better terms. Since the 2019 mortgage reform, the destination bank covers most of the switching costs (notary, registry, agency). You only pay for the appraisal (between 300€ and 500€) and the subrogation fee, if included in your contract.
Calculate the net monthly savings after deducting costs. A practical rule: if the annual saving exceeds the total cost of the switch, the operation is profitable. With mortgages over 150,000€ and more than 10 years remaining, subrogation is usually worthwhile.
Quick tips
- Use the variable mortgage calculator to compare what you would pay with the current spread vs. the new one before making any decision.
