ISO 15022 Data Field Dictionary

MT530 Scope

This message is sent by an account owner to an account servicer (account servicing institution). The account owner will generally be a financial institution that has an account with a local Central Securities Depository (CSD) or with an International Central Securities Depository (ICSD).

It is used to request the modification of a processing indicator or other non-matching information. In markets where this applies (for example, securities market infrastructures with no pre-settlement matching process), it is used by a party to approve, cancel or reject a transaction instructed by the counterparty.
