This lesson provides a comprehensive overview of the key legal and regulatory frameworks governing ethical conduct in banking, highlighting both U.S. and European approaches.

6.1 Understanding the Role of the Regulator
The regulator’s function is to identify, evaluate, and manage risk to protect depositors, ensure financial stability, and maintain public trust . Regulators operate on a spectrum from rules-based regulation (prescribing specific actions) to principles-based regulation (setting out broad principles and expecting firms to interpret and apply them) . In the U.S., the system is characterized by multiple agencies (Federal Reserve, OCC, FDIC, SEC, CFPB), while Europe features a layered system combining national authorities with EU-level bodies like the European Central Bank (ECB) and the European Banking Authority (EBA).

6.2 Key U.S. Regulatory Frameworks
U.S. banking regulation is shaped by a series of landmark statutes:

  • Bank Secrecy Act (BSA) and USA PATRIOT Act: The cornerstone of U.S. AML/CFT efforts, requiring customer identification programs (CIP), transaction monitoring, and Suspicious Activity Reporting (SAR) .

  • Sarbanes-Oxley Act (SOX): Enacted in response to corporate scandals, SOX establishes strict requirements for corporate governance, financial reporting, and internal controls, with significant penalties for non-compliance.

  • Dodd-Frank Wall Street Reform and Consumer Protection Act: A comprehensive reform act passed after the 2008 financial crisis, which established the Consumer Financial Protection Bureau (CFPB), introduced the Volcker Rule, and strengthened oversight of systemic risk .

  • Equal Credit Opportunity Act (Regulation B): Prohibits discrimination in any aspect of a credit transaction .

  • Truth in Lending Act (Regulation Z): Requires clear disclosure of loan terms .

6.3 Key European Regulatory Frameworks
European banking regulation is increasingly harmonized through EU directives and regulations:

  • Capital Requirements Regulation (CRR) and Directive (CRD IV/CRD V): Implement the Basel III standards in Europe, setting capital, liquidity, and leverage requirements for banks .

  • Anti-Money Laundering Directives (AMLD): The EU’s AML/CFT framework, currently on its 5th and 6th iterations, which are transposed into national law by member states .

  • Payment Services Directive 2 (PSD2): Opened up the payments market to new entrants, introduced Strong Customer Authentication (SCA), and mandated open banking .

  • General Data Protection Regulation (GDPR): Establishes comprehensive rules for the collection, processing, and storage of personal data, with significant penalties for non-compliance .

  • Sustainable Finance Disclosure Regulation (SFDR): Requires financial institutions to disclose how they integrate ESG risks and impacts into their investment decisions.
