ISO 15022 Data Field Dictionary

MT518 Scope

This message is sent by an executing party to its trade counterparty.

It is used to confirm the details of a trade.

It may also be used to:

  • request the cancellation of a previously sent confirmation

  • re-send a confirmation previously sent

  • provide a third party with a copy of the message (be it the confirmation or request for cancellation) being sent.

This message may include, where necessary, the settlement details of the trade.

The market confirmation may be:

  • exchanged directly or via an ETC service provider between two trade counterparties for mutual comparison of the trade details

  • sent by one trade party to allege the trade against its counterparty, either directly or via an ETC service provider.

MT518 Usage Rules

  • When an instruction is sent to a party other than the original Receiver, this original Receiver is identified in the other parties sequence as :95a::MERE (Recipient of the Message).

  • The receiver of financial instruments must be specified in the settlement parties subsequence.

  • When a broker is identified as a confirming party, the party capacity (:22F::TRCA) must be specified.

  • When an ETC service provider transfers a message from one institution to another, and when the originator of the message is not already identified in the confirmation parties sequence or the settlement parties sequence, then the originating party is identified in the other parties sequence as :95a::MEOR (Originator of Message).

  • The Receiver of a request to cancel must advise the requesting party that the request has been accepted or denied in an MT 509 Trade Status Message.
