Common Domain Model (CDM) for repo and bonds


2 July 2021 ICMA is cooperating with ISDA, ISLA and REGnosys to extend the Common Domain Model (CDM) to include repo and, by extension, outright bond transactions.

The CDM is a standardised, machine-readable and machine-executable blueprint for how financial products are traded and managed across the transaction lifecycle. ICMA is developing the CDM to provide an unambiguous, digital representation of repo and bond transactions in the form of code. It builds on legal definitions from the Global Master Repurchase Agreement (GMRA) and the ERCC Guide to Best Practice in the European Repo Market.

The CDM for repo and bonds is designed for use by repo market participants transacting in various repo structures and currencies, using different execution venues, protocols, and vendor solutions and by market and also for market infrastructures and vendor firms in repo and collateral markets.

Member firms have actively contributed to this cross-industry initiative by providing guidance and test data through regular ICMA CDM Steering Committee (SteerCo) meetings. The initial focus of the group has been to model a standard fixed-term repo, with a single ISIN as collateral, which is the most commonly transacted repo structure. Lifecycle events in the initial phase comprise trade execution, clearing and settlement. Modelling work has also included the mapping and ingestion of FIX 4.4 messages to CDM. Additionally, a bond transaction has been modelled so that the fundamental data points required for settlement can be represented in the CDM.

Implementation of the CDM will deliver industry wide efficiency gains for many internal processes eg trade execution and confirmation, risk management, regulatory reporting, reconciliations and settlement; improve interoperability between market infrastructures, and lay the foundation for innovation using technologies such as distributed ledger and cloud services.
