STS Digital to Accept and Pledge USDM1 Across Derivatives and Structured Products Books

Bermuda-regulated principal dealer adopts the world's first natively issued, USD-denominated sovereign bond as collateral under industry-standard derivatives and financing documentation

STS Digital Ltd., a Bermuda-regulated principal trading firm specializing in digital asset derivatives, structured products, and institutional liquidity solutions, today announced that it will accept USDM1 from eligible counterparties and pledge the instrument as collateral across its over-the-counter derivatives, structured products, and financing relationships. Through its institutional-grade trading infrastructure and principal market-making model, STS Digital provides institutional counterparties with access to deep liquidity, advanced derivatives capabilities, and bespoke solutions across digital asset markets. The adoption of USDM1 further expands STS Digital's commitment to bridging traditional financial infrastructure with the next generation of digital asset markets.

USDM1 brings onchain collateral with 24/7 transferability into established institutional derivatives frameworks. Although corporate digital dollar instruments are transferable onchain, for institutions, perfecting security interests in them can present challenges. As instruments, they are often not covered in industry netting opinions. As a result, their ability to provide collateral and capital efficiencies is often limited.

USDM1 can be used as initial or variation margin under standard derivatives documentation supporting legally enforceable netting sets, and may reduce unsecured counterparty exposure and the amount of other collateral required to support a portfolio.

The economic significance of close-out netting is well established in traditional derivatives markets. Bank for International Settlements data show that, at year-end 2025, legally enforceable netting reduced the gross market value of outstanding OTC derivatives by approximately 85.3%, or $19.4 trillion. USDM1 brings onchain collateral into the frameworks supporting these efficiencies.

USDM1 is compatible with repo and secured-financing arrangements under standard GMRA and GMSLA documentation and accrues a sovereign coupon. It enables title-transfer repo, collateral substitution and reuse within established institutional frameworks. When held unencumbered, USDM1 maintains look-through to the credit of pledged US Treasury instruments and supports treatment as Level 1 HQLA under Basel standards.1

Maxime Seiler, CEO of STS Digital, said: "As a principal derivatives dealer, collateral efficiency directly affects how we price, fund and scale our book. Accepting USDM1 from eligible counterparties, pledging it across our own trading and financing relationships and utilizing it in structured products supports more efficient inventory financing, tighter client pricing and greater trading capacity per dollar of balance sheet."

Jordan Goldman, President and Chief Operating Officer of M1X Global, said: "STS Digital is one of the most active and sophisticated crypto derivatives dealers. As digital assets enter a new phase of institutional adoption, USDM1 connects onchain markets with the legal, collateral and risk-management frameworks regulated institutional counterparties require while preserving the benefits of 24/7 settlement."
