The Common Domain Model (CDM) is a standardised, machine-readable and machine-executable data and process model for how financial products are traded and managed across the transaction lifecycle. The CDM is based on cross-industry collaboration between ICMA, ISDA and ISLA and facilitates trade processing of repo, securities lending, bond and derivatives transactions.
The CDM Showcase returned in 2025 for its third annual edition. The event covered themes of innovation in trading and lifecycle management, optimising collateral management, DRR and regulatory reporting, and the future of the market more broadly.
The CDM is hosted at FINOS under the FINOS Community Specification License 1.0

CDM for repo and bonds
ICMA completed phase 2 of its CDM project for repo and bonds in February 2023. The CDM now enables firms to automate trade execution, clearing, settlement and associated lifecycle events and processes of a wide array of repo transactions and features:
- Fixed-rate and floating-rate repos
- Fixed-term and open repos, repos with an extended notice period (known as “evergreens”), extendibles
- Lifecycle events and processes, including re-rate, repricing, interest payments, opening and closing of positions, collateral substitution, partial delivery, shaping, pair-offs and termination
ICMA’s CDM Steering Committee provides guidance and technical input as and when required. The SteerCo brings together banks, investors, trading venues, CCPs, ICSDs, law firms and vendor firms. The group includes front office, middle/back office, data modelling, IT and legal experts.
ICMA’s CDM Implementation Working Group is designed to assist IT teams and developers in designing and implementing CDM-based applications for repo trading and post-trade. On 23 August, the working group convened a meeting with the objective of advancing the adoption of the CDM across the repo industry.
