Corporate Governance cycles are related to corporate bankruptcies and the negligence of the board of directors, which are more common when a long period of economic expansion is followed by a period of crisis, which demonstrates failures in Corporate Governance. The main objective of the research is to analyze the impact of variables associated with governance, structure, and economy on the economic and financial performance of banking institutions in Portugal. In the model, a risk measure is used to determine whether Corporate Governance has an impact on a bank's risk-taking, the Impairment Ratio for Credit to Customers in relation to Assets. After performing the significance test for each of the variables (student t test), it is possible to determine that the following variables will be excluded: Bank Size (LNAT), Customer Deposits (LNDEP), Interest Rate (TXJUR) . We accept the following variables Corporate Governance (CG); Financial Autonomy (CPAT); Return on Average Assets (ROAA); GDP Rate Variation (TXPIB) and Inflation Rate (TXINF) .\u003Cbr>Keywords: Corporate Governance, e-governance, OLS, Banks, Impairments. |  |\n| INTRODUCTION |  |  |\n| Effective corporate governance practices are essential to achieving and maintaining societal trust in the banking system, which is essential for the smooth functioning of the financial sector and the economy as a whole. Bad Corporate Governance can contribute to bank failures, which in turn can represent significant costs due to their potential impact on the macroeconomic system. Added to this is the risk of contagion to the entire sector, which may, at the limit, jeopardize the financial system, as was evident in the international financial crisis that began in mid-2007 . In fact, in addition to their responsibilities towards shareholders, banks also have an obligation to answer to their depositors and other recognized stakeholders, |  | In Portugal, the IPCG – Instituto Português de Corporate Governance, a private law association, established in 2003, has the mission of “to establish itself as a center of excellence for reflection on matters related to corporate governance, disseminating and debating ideas and concepts on good corporate governance practices and contributing to the strengthening of ethics, accountability and transparency in their application.”(IPCG 2020).\u003Cbr>As for the objectives of the study, these allow indicating the main intention of the investigation, corresponding to the final product that is intended to be achieved.
