Derivative markets are global by nature. It is important that national and regional rules recognise this, and are compatible across jurisdictional lines. Inconsistencies between jurisdictions’ regulation or implementation timeframes can lead to market fragmentation. Mandatory Clearing, Margin, Recognition of CCPs, Benchmarks and Trade Execution are at the heart of the Cross-Border debate. As the US and EU reflect on their rules, work continues in Asia with regulators considering trade execution mandates, and Risk-Free Rates are being reviewed around the globe. This symposium, bringing together experts on Cross-Border issues, will assess the consequences and challenges arising from the implementation of the rules, and the obstacles moving forward.
