The International Organization of Securities Commissions (“IOSCO”) has announced that nine further securities regulatory authorities had been invited to become full signatories of the IOSCO Multilateral Memorandum of Understanding concerning Consultation, Cooperation and the Exchange of Information ("MoU"). The MoU provides a mechanism through which securities regulators share with each other essential investigative material, such as beneficial ownership information, and securities and derivatives transaction records, including bank and brokerage records. It sets out specific requirements for the exchange of information, ensuring that no domestic banking secrecy, blocking laws or regulations prevent the provision of securities enforcement information amongst securities regulators.
