DEX VERSION 27.1 available to test

The November 2021 software release includes changes required for the enhancements to the CREST Term DBV service. This functionality is now available to test in the simulator ahead of its go LIVE launch in Euroclear on Monday November 22nd 2021.

This new release is mainly centered around DBV and Term DBV’s. Key changes include :

  • Settlement timetable and Diary Events
  • Removal of the 2 Year maximum Return Date on a Term DBV – NDDN
  • Open End Term DBV (Gilt/Fixed Income only)
  • Term DBV Amendment Message – ARPA

Additional validation has been added to the simulator inline with Euroclear guidance relating to the Return Date :

  • A TDO for an Equity cannot have a Return Date greater than T+1

If any the above additional validation will impact on your current testing before the go LIVE date in November then please contact the support desk via email at support@sfl.co.uk to discuss your requirements.

Message Version Changes

There are no version changes to the NDDN message. However there are changes relating to how the Return Date is populated and used. This change will determine whether your message will create an Overnight DBV (DBV) or a Term DBV (TDO) transaction going forward.

There are no version changes to the ARPA message. However there are changes relating to existing fields on the current message version and how they are used i.e. Effective Date & Return Date.

Full details on the updated functionality and validation are in the new edition of the FT DEX Version 27.1.

Please visit the Euroclear website for all the latest up to date documentation relating to this release including the new whitebook Term DBV Enhancements July 2021.
