Recital 73

Interoperability arrangements are important for greater integration of the post-trading market within the Union and regulation should be provided for. However, as interoperability arrangements may expose CCPs to additional risks, CCPs should have been, for three years, authorised to clear or recognised in accordance with this Regulation, or authorised under a pre-existing national authorisation regime, before competent authorities grant approval of such interoperability arrangements. In addition, given the additional complexities involved in an interoperability arrangement between CCPs clearing OTC derivative contracts, it is appropriate at this stage to restrict the scope of interoperability arrangements to transferable securities and money-market instruments. However, by 30 September 2014, ESMA should submit a report to the Commission on whether an extension of that scope to other financial instruments would be appropriate.
