BNY and Citadel Securities have completed the first use of a tokenized asset on a major triparty repo platform, using a tokenized 2-year U.S. Treasury note as overnight collateral. The security settled within minutes on BNY's private digital ledger instead of the standard T+1 cycle. It then moved straight into an overnight triparty repo, with BNY providing cash against the tokenized collateral.

The workflow started conventionally. Citadel Securities bought the 2-year Treasury note through BNY on Tradeweb. After execution, a tokenized representation of the security was recorded on BNY's ledger and settled near-instantly. The token then served as collateral in the repo leg.

That chain matters for desks. It shows tokenized Treasuries moving through the full institutional lifecycle — execution, settlement, financing — in one connected digital workflow, rather than stopping at issuance.

What changes for collateral desks?

The core change is settlement speed turning into funding speed. A Treasury that settles in minutes becomes available as collateral in minutes, and BNY frames this as a step toward greater mobility and faster liquidity access in the world's deepest government bond market. For collateral managers, that compresses the gap between buying an asset and financing it.

Carolyn Weinberg, Chief Innovation & Market Transformation Officer at BNY, said: "This transaction demonstrates what becomes possible when tokenized assets are used in institutional workflows. By using a tokenized representation of a U.S. Treasury across both settlement and financing, we are enabling more connected, efficient and always-on financial system."

Brian Ruane, Global Head of Clearance and Collateral Management, Credit Services and Corporate Trust at BNY, framed the pressure on infrastructure directly: "As Treasury market activity becomes more continuous, the infrastructure supporting liquidity, funding and collateral has to keep pace. This transaction shows how tokenized collateral can help reduce friction while still using the trusted market structure participants rely on."

That last point is the sell-side takeaway. The trade ran on existing triparty market structure, with tokens replacing the settlement layer rather than the legal and collateral framework around it.

What are the participants claiming?

Separate the measured from the asserted here. What is demonstrated: one transaction, one tenor, one counterparty pair, settled on a private ledger with near-instant finality. What is asserted: broader operational efficiency, transparency and reduced friction across the trade lifecycle.

Dan Doherty, Digital Assets Operations Lead at Citadel Securities, said: "Efficient movement of high-quality collateral is fundamental to well-functioning markets. We're pleased to work with BNY on a practical use case that shows how tokenized U.S. Treasuries can move from settlement into financing more efficiently."

Laide Majiyagbe, Global Head of Markets at BNY, called the trade "a real example of how tokenization solves for client needs, leveraging both digital rails and traditional infrastructure."

Note the scope. This is BNY's private ledger, not a public chain, and it is a single pilot transaction rather than a production volume figure. BNY has not published throughput or cost data for the workflow.

What comes next?

BNY's roadmap has two tracks:

• Digital cash and tokenized deposits. BNY plans additional capabilities to support on-chain settlement and financing for institutional clients.
• Extended operating hours. BNY expects to lengthen hours on its traditional settlement platforms for Fed-eligible securities and U.S. triparty transactions, extending into European and Asian trading hours next year.

The bank argues tokenization and longer operating hours evolve together, supporting programmability, transparency and more predictable settlement outcomes toward 24/7 markets. It laid out the argument in a BNY Institute paper on the next evolution of the U.S. Treasury market.

For now, the transaction is a proof point, not a volume story. Whether tokenized Treasuries move from pilot to routine collateral depends on what BNY ships next year in deposits, operating hours and platform reach.
