The EU AML 4th Directive establishes a transnational framework aimed at harmonizing anti-money laundering measures and enhancing the assessment of financial institutions' risks. Key components include the focus on beneficial ownership, the emphasis on ongoing customer due diligence, and the integration of various risk factors in compliance measures. Financial institutions must regularly evaluate their risks and ensure that their customer due diligence processes are both effective and adequate in addressing the inherent risks associated with their clients.
