GDF -UKEU TMMF-report-1
The Global Digital Finance (GDF) Working Group’s 2025 TMMF Report presents a comprehensive examination of tokenized money market funds (TMMFs) as eligible collateral in European and UK markets. The document details six sandbox simulations that demonstrate end‑to‑end workflows—from bilateral variation‑margin posting to tri‑party repo funding and real‑time settlement via both DLT and legacy SWIFT/FIX channels. It analyses operational feasibility, risk‑management enhancements, and legal‑regulatory alignment, concluding that tokenized MMFs can be used as title‑transfer collateral under English law without introducing new legal risks. The report outlines a decision‑tree for tokenization structures (digitally native, digital twin, asset‑backed), evaluates the impact of legal form on collateral eligibility, and applies the Particula Digital Asset Risk Framework (PDARF) to rate a BlackRock token issuance. Policy recommendations call for clarified legal guidance, interoperability standards, eligibility recognition under EMIR/CRR, and measures to drive market adoption. Appendices provide detailed legal analysis, lex situs considerations, and a summary of benefits for buy‑side and sell‑side participants, reinforcing the case for immediate industry and regulator action.
Topics
Simulation 5 – Triparty Repo Funding of Tokenized MMFs
Demonstrates a workflow where Commerzbank posts variation margin to UBS, which then funds a digit‑ally native UBS MMF via a ten‑minute intraday repo with State Street, using Fireblocks custody, Ownera routers, and the USD FnPS testnet for cash settlement.
Tokenization Structures Decision Tree – Digitally Native, Digital Twin, Asset‑Backed
Presents a three‑branch decision framework that classifies tokenized MMFs based on the role of the transfer agent’s register, guiding legal and operational design choices.
Legal Form Impact on Collateral Use
Analyzes how different tokenization structures affect title transfer, custodian acceptance, regulatory eligibility, and enforceability in insolvency scenarios.
PDARF Digital Asset Rating Framework Applied to Tokenized MMFs
Describes the Particula Digital Asset Risk Framework (PDARF) assessment that assigned an AAA rating to a BlackRock token issuance, highlighting structural, counterparty, and underlying risk dimensions.
