Operating Models

An operating model describes the way a Participating Institution interacts with the DDM Program to route deposits, process activity, and manage its participation in the network. Each model outlines the Participating Institution's flow of funds, data, and operational responsibilities based on its internal systems and business structure. The DDM Program uses operating models to accommodate the different ways Participating Institutions originate deposits, connect to the network, and process daily activity. These models provide a consistent framework so each Participating Institution can participate according to its configuration while the DDM Program maintains standardized processing and settlement behavior.

Primary Operating Models

The DDM Program supports two primary operating models that define how a Participating Institution participates in the daily movement of deposits.

Direct-Source

In a Direct-Source model, the Sending Institution acts as agent of its Customers and sends customer deposits directly into the DDM Program. R&T serves as the Administrator, while the DDM Program's designated institution serves as the Custodian and Settlement Bank.

Indirect-Source

In an Indirect-Source model, the Source Institution acts as agent of its Customers and sends Customer Deposits to a Sending Institution, which then sends those deposits into the DDM Program on the Source Institution's behalf. R&T serves as the Administrator, while the DDM Program's designated institution serves as the Custodian and Settlement Bank.

For both the Direct-Source and Indirect-Source models, an affiliate of R&T, Stable Custody Group II LLC, serves as Sub-Custodian for the DDM Program.
