Banking law has always played a crucial role in the economy of businesses and retail customers. The complex national and international regulatory framework has seen banks, over the last decades, face financial crises, mergers and acquisitions, and the establishment by the EU of safeguard mechanisms to protect businesses and consumers. The wide range of services developed by the banking system, from current account management to credit operations, to more complex investment services and the advent of so-called digital banking, offers opportunities but also risks, especially for saver clients. It is fundamental for banks to comply with the regulations in force, a pillar for financial stability and trust in the banking system. Understanding these dynamics is essential for safely navigating the banking and financial sector, ensuring transparency and reliability in transactions.
