This report is the sixth progress report by the FSB on implementation of OTC derivatives reforms, and comes four years after the G20 agreed to undertake reforms to global OTC derivatives markets. The report includes an update on international, national and regional progress in finalising standards and implementing reforms to fulfil these commitments. As a special focus, this report draws on a number of information sources to review market participants' practical readiness to meet the requirements of reforms as they are implemented.
