Virtu Financial, M1X Global and Tradeweb have executed what they claim is the first fully on‑chain repo transaction using a natively issued sovereign digital bond as collateral, completing the full cycle – execution, settlement and repurchase – in less than ten minutes.
The bilateral trade, conducted between regulated institutional counterparties on Tradeweb, mirrored the structure of a conventional sovereign‑collateralised repo but replaced traditional settlement rails with atomic, on‑chain delivery across both legs. The firms said the workflow eliminated intraday balance sheet inflation and settlement exposure associated with T+1 infrastructure, enabling same‑day collateral reuse.
The securities leg of the transaction used USDM1, a sovereign digital bond issued natively on chain by the Republic of the Marshall Islands. Structured under New York law in the style of a fully collateralised Brady bond, USDM1 is backed 1:1 by short‑dated US Treasuries held in bankruptcy‑remote custody and classified as a UCC Article 8 investment security. It is eligible for inclusion in ISDA and GMRA close‑out netting sets and delivers materially lower RWA consumption than corporate payment stablecoins or tokenised MMF shares.
Jordan Goldman, president and COO at M1X Global, said: “Derivatives and secured financing markets have been waiting for collateral that works across institutional and digital rails simultaneously. USDM1 is a secured sovereign digital bond – not a stablecoin, not a tokenized fund, not a CBDC.”
Virtu’s head of rates sales, Dan Eckstein, added that capital efficiency “shows up directly in our ability to deploy working capital and serve clients”, noting that USDM1 addresses collateral constraints that have limited the scale of on‑chain markets.
Liz Kirby, head of market structure at Tradeweb, said tokenisation represents an important next step in electronic trading. “Digitally native sovereign collateral and atomic settlement can enhance collateral capital efficiency and modernise repo workflows, all while maintaining the institutional standards market participants have come to expect.”
USDM1 is available through Tradeweb with institutional custody provided by Anchorage, BitGo and tZERO, and is supported by FDIC‑insured Bank of Guam. The instrument was structured with counsel from Cleary Gottlieb to support title‑transfer repo, collateral substitution and reuse under standard ISDA and GMRA documentation.
The Republic of the Marshall Islands issues USDM1 under a New York law indenture with an explicit waiver of sovereign immunity. As a dollar‑denominated sovereign obligation backed by US Treasuries, it carries no FX or convertibility risk and provides holders with enforceable rights to par redemption and a perfected first‑priority security interest in collateral under UCC Articles 8 and 9.
