Understanding the Data: Spain's Mortgage Market Reaches Historical March Peak

The latest monthly data released by the National Statistics Institute (INE) shows that the number of residential mortgages constituted in Spain reached 46,661 in March. This represents a 9% year-on-year increase compared to the same month in 2025, marking the highest figure recorded for a month of March since 2010.

With this latest interannual advance, the signing of residential mortgages has now registered 21 consecutive months of growth, although the pace moderated from the 16.3% increase seen in February.

To understand the current lending landscape, we have broken down the precise metrics provided by the official INE data.

1. Key Volume and Value Metrics

The statistical data highlights significant growth in both the total volume of loans and the average capital borrowed:

• Average Loan Value: The average amount for a residential mortgage reached €174,132 in March, reflecting a 10.1% increase compared to the same period last year.
• Capital Lent: The total capital lent by banks grew by 20% year-on-year, surpassing €8,125 million.
• Quarterly Performance: Looking at the first quarter as a whole, residential mortgage originations grew by 9.7% year-on-year, totaling more than 131,500 operations. Over the first three months, total capital lent grew by 21.5%, and the average loan amount rose by 10.7%.
• Month-on-Month Evolution: Comparing March directly to February, the number of residential mortgages increased by 2.4%, the total capital lent grew by 2.9%, and the average loan amount saw a modest uptick of 0.5%.

While overall property sales across Spain have seen a slight structural slowdown, this strong surge in mortgage volume highlights that buyers are increasingly relying on financing to secure properties amidst sustained, robust property valuations.

2. Interest Rates and Loan Terms

The metrics show that borrowing rates continue to remain steady below the three percent threshold, with an average repayment term established at 25 years.

• Average Interest Rate: The average interest rate for home loans fell to 2.84% in March, dropping below the 2.88% recorded in February. This is the lowest value recorded since October (2.81%), marking 14 consecutive months where the average rate has remained below 3%.

Market Insight for Prospective Buyers: While March’s official figures remained highly competitive, early forward-looking indicators from April and May suggest that lenders are beginning to adjust rates upward due to broader macroeconomic pressures and energy costs. If you are looking to lock in a sub-3% rate, timing is everything.

3. The Choice Between Fixed and Variable Rates

The structural breakdown of how loans are being configured shows a clear preference among buyers for stability:

• Fixed-Rate Mortgages: Accounted for 63.8% of all residential mortgages signed during March, with an average initial interest rate of 2.83%.
• Variable-Rate Mortgages: Accounted for the remaining 36.2% of operations, carry an average initial interest rate of 2.86%.

4. Regional Extremes

In terms of sheer volume, Catalonia led the nation with 8,663 new mortgages signed in March, closely followed by Andalusia (8,600) and Madrid (7,727).

While the national average growth sat at 9%, the pace of mortgage signatures varied significantly across different autonomous communities. The highest year-on-year increases during the month of March were concentrated in three specific regions:

• Navarra: Registered the highest growth with an increase of 60.4%.
• Aragón: Followed with a year-on-year increase of 45.4%.
• Madrid: Documented an upward shift of 19.1%.

Conclusion

The data from the INE shows a consistent upward trend in mortgage creation that has persisted for nearly two years. With average rates remaining below 3% for over a year and fixed-rate structures remaining the choice for nearly two-thirds of operations, the underlying numbers paint a very clear picture of the current lending environment.
