ISO 15022 Data Field Dictionary

MT538 Scope

This message is sent by an account servicer (account servicing institution) to an account owner or its designated agent. The account servicer may be a local agent (sub custodian) acting on behalf of their global custodian customer, or a custodian acting on behalf of an investment management institution or a broker/dealer.

This message is used to provide the details of increases and decreases in securities with a given status within a holding, that is, inter-position transfers, which occurred during a specified period, for all or selected securities in a specified safekeeping account which the account servicer holds for the account owner.

This message may also be used to respond to a request for statement/status advice, that is, the MT 549 Request for Statement/Status Advice and to report that there are no increases and decreases within a holding.

MT538 Network Validated Rules

  • C1 If the Activity Flag (field :17B:ACTI) in sequence A General Information is N, then sequence B must not be present. Otherwise, sequence B is mandatory.

    Sequence A

    if field :17B::ACTI is ...

    Sequence B is ...

    N

    Not allowed

    Y

    Mandatory

  • C2 The 'Balance From' must be different from the 'Balance To': within each occurrence of subsequence B2 Sub-balance, the Sub-balance Type of field :93A::FROM must be different from the Sub-balance Type of all occurrences of field :93A::TOBA in subsequence B2a Intra-Position Movement.

  • C3 If the message is a cancellation, that is, Function of the Message (field 23G) is CANC, then subsequence A1 (Linkages) must be present at least once in the message, and in one and only one occurrence of A1, field :20C::PREV must be present; consequently, in all other occurrences of A1, field :20C::PREV is not allowed.

    Sequence A

    if field :23G: is ...

    Then subsequence A1 is ...

    And field :20C::PREV is ...

    CANC

    Mandatory (minimum one occurrence of A1 must be present)

    Mandatory in one occurrence of subsequence A1, and not allowed in all other occurrences of subsequence A1

MT538 Usage Rules

  • This statement is used by the account servicer to report increases or decreases within the holding (movements from one sub-balance, or availability status, to another) to the account owner.

  • The frequency of the statement must be bilaterally agreed between the account servicer and the account owner.

  • Since a SWIFT message as sent, is restricted to the maximum input message length, several messages may be needed to accommodate all the information.
