The global standard-setter for securities regulation, with principles and MMoUs that shape cross-border market-abuse cooperation.
IOSCO is the international body that brings together national securities regulators — the SEC, the FCA, BaFin, ESMA's member NCAs and roughly 130 others. Founded in 1983 and headquartered in Madrid, it sets the global principles for securities regulation and coordinates cross-border enforcement.
Two IOSCO outputs are particularly relevant to the financial-defence space: the IOSCO Objectives and Principles of Securities Regulation, which national regimes (including the EU's MAR/MiFIR) are measured against; and the IOSCO MMoU — the multilateral memorandum of understanding under which securities regulators share investigative information across borders. For market-abuse cases that span venues and jurisdictions, the IOSCO MMoU is often the operating channel.
Marengo's MAR-supervision capability operates in a world where cross-venue cases are routinely escalated through IOSCO MMoU channels. The platform's evidence-chain output is structured so that a national securities regulator can include it in MMoU information requests without re-derivation.
