ISO 15022 Data Field Dictionary

Note

The use of this message type requires Message User Group (MUG) registration.

Important!

The user header of the message (block 3) is mandatory and must contain a code in the Validation Flag field 119 ( {3:{119:xxxx}} ) to identify the exposure type or collateral reason.

These codes may be used for routing purposes.

MT503 Scope

This message is sent by the collateral taker or its collateral manager to the collateral giver or its collateral manager. This message is also sent by the collateral giver or its collateral manager to the collateral taker or its collateral manager.

When sent by the taker, it is used to:

  • request new collateral at the initiation of an exposure

  • request additional collateral

When sent by the giver, it is used to:

  • request the return of collateral

  • recall the collateral upon the termination of an underlying exposure.

This message is also used by the taker or the giver to request the cancellation of a previously sent collateral claim.

This message must not be used to initiate a substitution of collateral.

The message may also be used to:

  • re-send a message previously sent (Subfunction of the message is DUPL)

  • provide a third party with a copy of the message for information (Subfunction of the message is COPY)

  • re-send to a third party a copy of the message for information (Subfunction of the message is CODU).

MT503 Format Specifications

The collateral claim consists of three sequences:

  • Sequence A General Information provides general information about the message and the collateral transaction, that is, the function of the message, the identification of the collateral transaction, the references of the linked messages, the identification of the underlying agreement(s), the identification of the parties, the reason for which collateral is needed (the exposure type), the identification of the collateral action and the contact information.

    Note

    More than one occurrence of the agreement is only authorised for cross-product collateralisation and when no overall master agreement is in place yet.

  • Sequence B Summary provides information related to the collateral position, that is, the identification of the exposed party, the total exposure amount, the total collateral amount held by the taker, the value of collateral to be added to or to be returned from the collateral held. The sequence contains an optional subsequence with the amounts taken into account to calculate the collateral position. These amounts are required for certain types of exposures. The subsequence also contains the valuation dates and the requested settlement date of the collateral.

  • Optional sequence C specifies the details of the collateral claimed. It is used by the taker only if the taker wants to receive specific collateral. It is used by the giver to specify the collateral it wants to pull out of the collateral held by the taker. The collateral can be securities, cash, documentary credits or bank guarantees.

MT503 Usage Rules

The exchange of information related to the trade itself as well as to the settlement of the collateral is done with the existing confirmation and settlement messages of the relevant categories (categories 2, 3, 5, 7, 9).
