(20)The duration of this Decision should therefore give enough time for the development of the clearing capacity of Union CCPs, exploring ways to enhance liquidity in those CCPs and to expand the range of clearing solutions on offer from Union infrastructures, including via the adoption of regulatory measures facilitating that process, in order to allow for a significant reduction of Union clearing members’ exposures to UK CCPs. This Decision should also give sufficient time for the review of the Union’s supervisory framework for CCPs. Accordingly, it is appropriate that this Decision expires 3 years after its date of application.
