(3)However, the reasons underlying Implementing Decision (EU) 2018/2030 remain, regardless of any extension of the period referred to in Article 50(3) of the Treaty on European Union. In particular, in the event of a withdrawal without an agreement after the extended period, potential risks persist in relation to certain services provided to Union operators by central securities depositories that have already been authorised in the United Kingdom and that cannot be replaced in the short-term. Therefore, Implementing Decision (EU) 2018/2030 should apply if the United Kingdom withdraws from the Union without an agreement.
