What is Euribor? And the spread that is added?
Euribor is the index most commonly used as a reference (i.e. to calculate the revision of variable interest rates) in mortgage loans. It comes from the average of the rates applied to euro deposit operations by the 50 most active banks in the European interbank market.
The Euribor is published for several maturity dates, but the one that is used as the official reference index (interbank reference) is one-year Euribor. If you want to find the latest published value, you can check this on the Bank of Spain website.
The spread is the margin added to Euribor when you take out your mortgage (if it is Variable or Mixed) so that Euribor + spread = the interest rate for your mortgage
