On 21 January 2021, the European Securities and Markets Authority (ESMA) published a final report on revised guidelines regarding written agreements between members of central counterparty (CCP) colleges. The objectives of the guidelines are to establish consistent, efficient and effective supervisory practices within the European System of Financial Supervision and to ensure the common, uniform and consistent application of Articles 18 and 19 of EMIR and of the Delegated Regulation on colleges. In particular, they aim to propose a standard written agreement to ensure the timely establishment and smooth functioning of a CCP college. The guidelines replace those adopted by ESMA on 4 June 2013. The guidelines will be translated into the official EU languages and published on ESMA’s website. The publication of the translations in all official languages of the EU will trigger a two month period during which Member State competent authorities must notify ESMA whether they already comply or intend to comply with the guidelines.
