  • By SWIFT ISO 15022 messages.
  • Delivery versus Payment – DVP;
  • Free of Payment – FOP;

The matching of operations occurs on the TARGET2-Securities (T2S) platform:

  • Mandatory matching fields, are those that must be included in the two settlement instructions registered in the system in order to allow the matching to occur;
  • Additional matching fields are those fields that have to match if they are filled in, in at least one of the instructions;
  • Optional matching fields, are those fields that may match with a filed with no value, but when provided in both instructions, the values have to match;
  • Matching fields and matching tolerances: two settlement instructions match if the difference between the settlement amount indicated by the seller and the buyer is lower than the tolerance amount. In this case the instructions will settle using the settlement amount specified by the seller:

Settlement of transactions occurs on TARGET2-Securities (T2S):

  • Settlement is processed in accordance with the rules established by INTERBOLSA as well as the operating rules of the T2S platform;
  • The settlement process includes a night time settlement period and a daytime settlement period in T2S –Timetable.


Before its settlement or cancellation, the Participant can amend the following fields:

  • Partial settlement indicator;
  • Link between different settlement instructions;
  • Settlement priority indicator (is not possible for partially settled instructions).
  • The hold functionality can be used at the moment of registration of the instruction or afterwards.
  • The total release functionality can be used at any time, and in this case the instruction will be immediately submitted to settlement, unless the intended settlement date (ISD) is on future date.
  • The partial release functionality can only be used from the SoD (Start of Day) on intended settlement date (ISD), at 18:45 CET, and the instruction will try to settle for the released quantity in the next partial settlement window.

    This functionality is only available for delivery of securities (DVP, DFP e DWP) and is possible for settlement instructions:
    • Matched and not cancelled;
    • Pending with Party ‘Hold’;
    • That allows partial settlement.
  • The partial release process only have the lifecycle on a single business day. In case the partially released quantity has not been completely settled by the end of the corresponding settlement cut-off time the process is automatically cancelled by T2S, i.e., the settlement instruction is set back on party hold for the original quantity.

The settlement instructions can be cancelled:

  • Unilaterally, by the Participant who has registered the instruction, if the matching did not yet occur;
  • By mutual agreement, after matching, at any time before the settlement is processed.

A settlement instruction is automatically cancelled if the instruction remains unmatched after 20 business days after: the intended settlement date, or the date of the last amendment of the instruction, whichever is the most recent date.

Warning” sent to the counterpart of the instruction, to inform that there is a instruction registered in the system waiting for the corresponding instruction of the counterparty for its confirmation.

The instructions can be sent with different levels of priority, from the highest to the lowest:

  • Level 3 – high priority;
  • Level 4 – normal priority.
  • Information (INFO) – for information purposes only, with no impact on the settlement processing;
  • Before (BEFO) – which means that a settlement instruction or settlement restriction settles before or, at least, at the same time as the linked settlement instruction or settlement restriction;
  • After (AFTE) – in this case the settlement instruction or settlement restriction, settles after or, at least, at the same time as the linked settlement instruction or settlement restriction;
  • All-or-none (WITH) – with this link, a settlement instruction or settlement restriction settles at the same time as the linked settlement instruction or settlement restriction. This can also be achieved by creating a Pool of Linked instructions;
  • A set of instructions specifying the pool reference of each instruction (linked type WITH or not informed).


Partial settlement procedures apply to all eligible settlement instructions, when full settlement is not possible due to a lack of securities in the following periods:

  • Night-time settlement period: in the last settement cycle;
  • Day-time settlement period: during the partial settlement windows defined for this purpose – Timetable.
