What is the IRPH in mortgages?

The acronym IRPH in mortgages stands for: Mortgage Loan Reference Index. It is an official indicator that some banks use to reference variable-rate mortgages in Spain. 

This benchmark is calculated based on the average interest rates on mortgages offered by the banks themselves. This particular feature has been the main source of criticism and controversy. 

You may also be interested in: fixed, variable, or mixed mortgages.

Types

In the past, the IRPH in mortgages was presented in several modalities. Over time, the regulation evolved and the number of active indices was reduced. We will break down the three types of IRPH for you; it should be noted that today only one of them remains active.

IRPH for savings banks

The IRPH for savings banks was a mortgage index calculated using the average interest rates on mortgages granted by savings banks. Published monthly by the Bank of Spain, it ceased to be used in 2013 as part of an evolution of the banking system.

IRPH of banks

It operated similarly to the previous one, but was based on the average interest rates on mortgages granted by banks. The Bank of Spain also published its value on a monthly basis. 

Like the previous one, it ceased publication in 2013 as part of a reform of benchmark indices. 

IRPH for all institutions

It is the only IRPH index that remains fully in force and continues to be officially published. It remains in force because the Bank of Spain considered it valid to replace the two previous indices in contracts that used them as a reference. 

Order EHA/2899/2011 forced many entities to replace discontinued indices with the current one. However, in some cases, they were replaced by other indices unilaterally and without due transparency.

How do they work?

The IRPH mechanism in mortgages works like any other variable-rate mortgage: the payment is recalculated periodically by adding the value of the index and a spread. 

Unlike the volatile Euribor mortgage rate, the IRPH is a more stable index but historically higher. This stability translates into higher payments for the consumer throughout the entire loan.

What is the difference between Euribor and IRPH?

Although both are reference indices for variable-rate mortgages, their characteristics and behavior are very different. In the following comparison table, we summarize the differences.

Understanding the above differences is a starting point for understanding why the IRPH has been so controversial. 

How can I find out if my mortgage has IRPH?

The first thing you should do is gather and organize your loan documentation. Then, to find out if your mortgage is linked to the IRPH, you can follow these recommendations.

Review of documentation.

Carefully review your mortgage deed. Look for the clause that refers to the variable interest rate. If you find any mention of IRPH, you will know that your mortgage is linked to this index.

Go to your bank.

If for any reason you do not have your mortgage documentation, contact your bank and request a detailed statement. It should include the index used to calculate your payments.

Seek Professional Advice

Consult a mortgage law professional. These specialists are familiar with legal jargon and banking documents. Therefore, they are the right people to analyze your mortgage deed and confirm whether your loan has IRPH or another index.

How to calculate it?

The IRPH value for mortgages is published monthly by the Bank of Spain in the Official State Gazette (BOE). To calculate your payment, you must add the IRPH value plus the spread agreed in your contract. 

Then, you must apply that percentage to the outstanding principal of your mortgage. For example, if the IRPH is 1.986% and your spread is 0.25%, the applicable interest rate will be 2.236% (1.986% + 0.25%).

Can you claim the IRPH on a canceled mortgage?

Yes, it is possible to claim that the IRPH is unfair in mortgages, even if your loan has already been paid off. The period for taking legal action does not begin when the mortgage is signed or paid, but when the consumer realizes that the clause is unfair.

How can I tell if the IRPH is unfair?

The Spanish courts, following the guidelines of the Court of Justice of the European Union (CJEU), will analyze whether the bank complied with the “double transparency control.”

  1. Formal transparency: The IRPH clause in the mortgage deed is reviewed to ensure it is clear, legible, and understandable to anyone.
  2. Material transparency: Did the bank inform the customer of the risks of the IRPH? This includes clearly explaining how the index was calculated and warning that its value was historically higher and less volatile than others. 

It is essential that the bank provide you with the information in a clear and precise manner. If this was not the case and you were not informed about the nature of the IRPH, the clause is likely to be considered unfair.

Advantages and Disadvantages for Consumers

Like any benchmark index, the IRPH has two sides to it. Although it has a good reputation, it offers some features that could be considered an advantage, but these are overshadowed by the economic disadvantages it entails. 

Advantages

  • Stability: The IRPH in mortgages is stable. This eliminates the risk of sudden increases in payments during times of economic uncertainty.
  • Predictability: Its low fluctuation allows consumers to have greater predictability in their monthly payments.

Disadvantages

  • Higher Cost: The IRPH value has always been higher than Euribor.
  • Lack of Transparency: The value is calculated using data from the banks themselves, which has raised doubts about whether it is an objective index.
  • Difficulty of Comparison: The complexity of calculating the IRPH makes it difficult to compare with other indices, such as Euribor. 

The main advantage of the IRPH, its stability, is outweighed by the disadvantage of its high cost. It is essential to understand both sides in order to comprehend how this index affects your finances.

Legal Status of the IRPH Mortgage Rate in Spain in 2026

The legal situation regarding IRPH remains complex. The Court of Justice of the European Union (CJEU) requires Spanish judges to analyze the transparency of the clause, but it has not declared it abusive by default. Therefore, each case must be evaluated individually.
