ICMA examines smart contracts in DLT bond markets

The International Capital Market Association has published a discussion paper titled “Smart contracts and DLT-based fixed income markets: What’s next?” The paper was written by Francisco Parente and draws on input from ICMA members, including participants in the DLT Bonds Working Group and the Bond Data Taxonomy Working Group. It maps how smart contracts are being applied across the securities lifecycle, from issuance and settlement to servicing, repo transactions and collateral management.

The paper reports that smart contracts are already in live use on several institutional DLT networks and in market applications. It identifies platform fragmentation and differing data models as barriers to wider adoption and describes where common smart contract templates and a shared data taxonomy could reduce duplication and help create interoperable systems.

Settlement is a central focus. The paper outlines legal and technical questions about digital settlement assets and what constitutes settlement finality when transfers occur across different ledger systems. It states that clarity on those topics is necessary to limit settlement risk and to allow DLT-based settlement to work with existing market infrastructure such as central securities depositories and payment systems.

Interoperability is treated as both a technical and a market governance issue. The discussion examines options for connecting different DLT platforms with one another and with legacy systems, and considers how industry-led standards might complement regulatory or official-sector frameworks. The paper highlights the need for collaboration among market participants, infrastructure providers and regulators to avoid isolated networks that cannot transact with each other.

Repo and collateral management are cited as practical areas for smart contract automation. The paper notes potential operational benefits from automating repo lifecycle events and collateral reuse while also raising questions about legal enforceability and cross-system settlement that would need resolution before broader uptake.

ICMA says it gathered feedback from members through workshops and working groups and thanks participants for their input. The paper invites comments from the wider industry on a series of questions that will inform ICMA’s future work on DLT bonds and the bond data taxonomy.
