The Banking Law establishes that the management and supervisory bodies of credit institutions in Portugal are responsible for defining, overseeing and implementing adequate governance to ensure the institutions' effective and prudent management, including the segregation of duties and the prevention of conflicts of interest. Further, banks must disclose information regarding the remuneration of corporate bodies and employees to the Bank of Portugal or the Single Supervisory Mechanism.
Following the 2008 banking crisis, the Banking Law was amended to protect depositors of all credit institutions and safeguard the stability of the EU banking system as a whole. Under the law, the Bank of Portugal may apply a number of resolution measures to failing institutions which do not involve obtaining prior consent from their shareholders or a third party. It can also create a resolution fund, which aims to provide financial support for the implementation of measures to help failing credit institutions.
The Portuguese supervisory system has changed following the recent establishment of a single supervisory mechanism and a single resolution mechanism, which are comprised of the European Central Bank (ECB) and national competent authorities. The ECB is responsible for the overall functioning of the single supervisory mechanism and the single resolution mechanism, as well as having direct oversight of eurozone banks in cooperation with national supervisory authorities.
