(17)The United Kingdom authorities are expected to inform the Union about all changes to the United Kingdom’s regulatory or supervisory framework affecting the provision of clearing services in the United Kingdom. The Commission, in cooperation with ESMA, will monitor any changes introduced in the legal and supervisory arrangements affecting the provision of clearing services in the United Kingdom, market developments and the effectiveness of supervisory cooperation, including prompt information exchange between ESMA and the Bank of England. The Commission may undertake a review at any time where relevant developments make it necessary to re-assess the equivalence granted by this Decision, including where the United Kingdom authorities do not effectively cooperate, do not allow for an effective assessment of the risk that UK CCPs pose to the Union or its Member States or the actions taken by UK CCPs or the Bank of England promote undue and unfair competition.
