What reda.049 is for

The AccountLinkCreationRequest message is sent by the instructing party to the executing/servicing party to request the creation of an account link between a securities account and a cash account in their system.

The instructing party - executing/servicing party relationship may be:

- Central Securities Depositories (CSD) who would like to publish account link static data, or

- a Corporate, or

- a Bank, or

- a Market Infrastructure, or

- a Market Data Provider.

The request is sent when the instructing party identified a gap in the account link coverage of the executing/servicing party. The instructing party needs this account link to be set-up at the executing /servicing party to perform its activities.

Initiator: instructing party.
