Which regulatory bodies cooperate when dealing with cross-border suspicious or unusual financial activity investigations?

The European Commission is the executive branch of the European Union responsible for proposing legislation and enforcing laws but does not directly engage in financial investigations. Its primary role is to ensure that EU regulations are implemented across member states rather than acting as a regulatory body for financial crime investigations.

The Wolfsberg Group is an association of major banks that aims to develop frameworks and guidance for the management of financial crime risks, particularly regarding anti-money laundering (AML) practices. However, it does not function as a regulatory body with enforcement powers or direct involvement in investigations, focusing instead on best practices and industry standards.

The Financial Action Task Force (FATF) is an intergovernmental body that sets standards and promotes measures to combat money laundering and terrorist financing. While FATF influences global policies and frameworks, it does not directly conduct investigations; rather, it provides guidance and assesses countries' compliance with its recommendations.
