Modifications and cancellations of market/reverse claims and transformations in Xact via SWIFT

With the change of referencing in messages related to settlement instructions generated from market claims and transformations, customers will be able to modify or cancel market/reverse claim instructions or transformation settlement instructions.

At present, these functionalities are only possible via Xact Web Portal and now they will be extended to Xact via SWIFT.

Customers will be required to use the reference populated in field :20C::PCTI of MT548 and include it in field :20C::PREV of their MT530 or MT540-MT543(CANC) messages.

This enables:

  • Modification via MT530: Change of the hold/release status;
  • Cancellation via MT540-MT543 (23G:CANC).

Instructions to be modified or to be cancelled must contain:

  • :22F::SETR//CLAI for market/reverse claims;
  • :22F::SETR//TRAD and 22F::STCO//TRAN for transformations.

Extension of transformation period

At present, LuxCSD performs transformations for pending matched trades only at the end of the day at 20:30 CET (on record date/entitlement date). If instructions are generated after the transformation process has taken place, those instructions will be rejected.

New processing cycles to transform pending matched trades will be introduced at 03:00 CET, 10:00 CET, 14:00 CET and 17:00 CET on maturity date (extension of the transformation period by one business day).

Customers instructing on an old or matured ISIN must respect the final deadline on maturity date at 16:45 CET.

Instructions on maturity date after 16:45 CET, will not be transformed but remain pending until they get rejected at 20:30 CET.
