ESMA has published its final report in response to its consultation paper on the proposed amendment introducing the possibility for EU CCPs to margin on a one day gross basis for clients' accounts (also referred to as the margin period of risk (MPOR)). As a result of strong support from the respondents, EMIR has made some clarifications or slight amendments, in particular on intraday margin calls and on entities belonging to the same group as clearing members. Following the US equivalence decision by the European Commission, the amended RTS would provide a level playing field between European and US CCPs of one-day MPOR.
