In February 2011, the International Organisation of Securities Commissions (“IOSCO”) published a report entitled Report on Trading of OTC Derivatives (“Trading Report”). The Trading Report set out a framework for international regulators to consider when implementing the G-20 commitment to trade all standardised over-the-counter (“OTC”) derivatives on exchanges or electronic trading platforms, where appropriate, by end 2012 at the latest. This follow-on report describes the different types of trading platforms currently available for the execution of OTC derivatives transactions in IOSCO member jurisdictions. Where possible, it also notes the differences relating to participant, product and geographic coverage. The intention of this follow-on analysis is not to revisit the conclusions contained within the Trading Report but instead give a factual presentation of the different trading models currently available so as to assist regulators and policy makers when developing or implementing derivatives trading policy proposals.
