Interoperability Challenges Keep Blockchain Repo Infrastructure in Early-Stage Deployment

A new industry report reviewing nearly a decade of distributed ledger technology applications in the repo market finds that while adoption has expanded in recent years, blockchain-based repo activity remains limited in scale and largely confined to closed institutional platforms.

The study, published by ICMA and authored by senior consultant Richard Comotto, examines 34 publicly disclosed examples of DLT-based repo transactions between 2017 and 2025, the majority of which were experimental pilots, proofs-of-concept, or simulations rather than fully scaled commercial operations.

Limited but growing commercial activity

While most initiatives remained experimental, the report highlights two platforms that have seen meaningful commercial usage: Broadridge’s Distributed Ledger Repo (DLR) platform and JPMorgan’s Kinexys infrastructure.

Together, these platforms are estimated to have processed up to approximately $3.7 billion in average daily turnover by the end of 2025, with activity concentrated primarily on Broadridge’s system.

Despite this growth, the report notes that DLT-based repo activity still represents a fraction of the broader U.S. repo market, which operates at a scale measured in trillions of dollars daily.

Walled gardens and limited interoperability

A key finding of the report is that the dominant commercial platforms operate as “walled gardens,” serving only existing institutional clients within their respective ecosystems.

While both Broadridge and JPMorgan have contributed to scaling real-world usage of distributed ledger infrastructure, the report argues that these systems remain fragmented and lack meaningful interoperability across platforms.

Efforts to connect different DLT-based infrastructures are underway, but the report suggests that significant technical and institutional barriers remain before a fully integrated market can emerge.

Where blockchain fits in repo markets

The report also examines how distributed ledger technology is applied across different stages of repo transactions, including pre-trade, execution, and post-trade processes.

It concludes that certain functions—such as collateral management, margining, and settlement—are more suitable for blockchain-based systems, particularly where precise timing and automation can improve efficiency.

However, it finds that traditional central limit order book trading and central clearing functions are less compatible with distributed ledger architectures in their current form.

Definition still evolving

The report defines a DLT repo transaction as one in which some post-trade processes occur on distributed ledgers, or where over-the-counter trading activity is executed within a distributed ledger environment.

This broad definition reflects the evolving nature of the market, where blockchain infrastructure is often integrated selectively rather than replacing legacy systems entirely.

Early-stage infrastructure rather than transformation

Overall, the report concludes that while blockchain-based repo markets have moved beyond purely theoretical experimentation, they remain in an early stage of development.

It highlights that most activity is still concentrated within controlled institutional environments rather than open, competitive markets, and that the transition toward fully interoperable, blockchain-native repo infrastructure remains a work in progress.

The second part of the ICMA study, expected later this year, will focus on the conditions required for wider adoption and the potential evolution of digital collateral and settlement frameworks across global repo markets.
