The Spanish Banking association (AEB in its Spanish acronym) is a professional association open to all Spanish and foreign banks operating in Spain. Even though the membership of the AEB is voluntary, the vast majority of banks operating in Spain are members of the association.
The AEB was established in 1977 under the law governing professional and trade associations. It is a legal entity with its own assets. In order to cover the administrative and operating costs of the association, its members pay annual fees proportional to their dimensions and activities.
