On 9 April 2021, the European Securities and Markets Authority (ESMA) published the interim simple, transparent and standardised (STS) notification templates for synthetic securitisations following amendments to the Securitisation Regulation. The interim templates allow originators to notify ESMA of synthetic securitisations that meet the STS criteria until the date of the application of the regulatory technical standards (RTS) specifying the content and the format of STS notifications for synthetic securitisations. The interim STS notification templates may be used by originators on a voluntary basis which may be subject to possible changes following the entry into force of the RTS.
