(83)In order to ensure the proper implementation of the interest rate benchmark reform of the FSB it is necessary to provide clarity to market participants that transactions entered into or novated before the entry into application of the clearing or margin requirements to OTC derivative transactions referencing an interest rate benchmark (legacy trades) will not be subject to the requirements as provided for in Regulation (EU) No 648/2012 when they are novated for the sole purpose of implementing or preparing for the implementation of the interest rate benchmark reform. Doing so should also prevent any risk that Union counterparties to those legacy trades find themselves unprepared when a specific benchmark is materially changed or discontinued, therefore alleviating related financial stability concerns. Such approach is in line with the international guidance from the Basel Committee on Banking Supervision (BCBS) and the International Organization of Securities Commissions (IOSCO).
