Introduction

Banking law and governance design in Spain refers to the legal and institutional framework that determines how banks are structured, supervised, managed, and held accountable. Spain’s banking governance model combines national banking regulations, European Union banking rules, prudential supervision standards, consumer protection requirements, and corporate governance principles.

Spanish banks operate within the framework of the European Banking Union, where supervision, resolution mechanisms, and capital requirements are coordinated at the European level. The design of banking governance focuses on maintaining financial stability, protecting depositors, ensuring responsible management, preventing misconduct, and promoting transparency.

The main institutions involved include the Bank of Spain (Banco de España), the European Central Bank (ECB) for significant institutions, the Single Resolution Board (SRB), and the Spanish National Securities Market Commission (CNMV) for listed banking entities.
