BNY settles a tokenised Treasury in minutes for Citadel repo
BNY said on 13 October 2026 that it completed a triparty repo workflow with Citadel Securities using a tokenised representation of a two-year US Treasury note, which it describes as the first use of tokenised assets on a major triparty repo platform. Citadel bought the note through BNY on Tradeweb, and the tokenised version settled within minutes, against the next business day (T+1) for the conventional equivalent.
What this demonstrates and tests is whether a tokenised security can do the job that matters most to a collateral desk, which is to be pledged quickly for cash. It is just one transaction though.
How the tokenised Treasury repo worked
The note was recorded on BNY's private digital ledger. Citadel then used it as collateral in an overnight triparty repo, with BNY providing the cash. In a triparty repo the custodian, here BNY, handles collateral selection, valuation and settlement between the two sides.
BNY says it plans to add digital cash and tokenised deposit capabilities, and to extend operating hours for Fed-eligible securities and US triparty settlement into European and Asian hours next year. BNY reported $62.6 trillion of assets under custody and administration at 30 June 2026.
Why minutes against T+1 matters for an overnight loan
An overnight repo lasts about one day. A purchase that takes a full business day to settle therefore waits as long as the loan itself would run. Settling in minutes means the same security can be bought and pledged within one session, which is the saving the exercise was designed to show. This comparison is a reading of the figures given, not a number BNY published.
Carolyn Weinberg, BNY's Chief Innovation and Market Transformation Officer, said the transaction "demonstrates what becomes possible when tokenized assets are used in institutional workflows." Dan Doherty of Citadel Securities said efficient movement of high-quality collateral is fundamental to well-functioning markets.
What the pilot leaves open
We don't know the name of the distributed ledger, the size or rate, or even the name of a regulator. The workflow also runs on a private ledger, so capability for interoperability with other custodians or venues is not known. A single completed trade is evidence that the workflow functions, not that repeated volume will follow.
CoinDesk headlined the event as a test, while BNY's wording is that the workflow was completed. The difference says a lot because a test can be switched off and a production workflow is harder to retire.
What it means for issuers of tokenised assets
Collateral use is one of the clearest demand-side tests for tokenised securities. Earlier coverage looked at ECB models for central bank money on-chain, the Treasury's DIGIT digital gilt and Ondo's tokenised notes. Each depends on a buyer being able to use the token as money-like collateral.
For founders and advisers building tokenised products, the question to ask any custodian is whether its tokens are accepted in its own financing workflows.
This is general information, not legal, tax or investment advice.
Key takeaways
BNY said on 13 October 2026 that it completed a triparty repo with Citadel Securities using a tokenised two-year US Treasury note, settled within minutes.
The workflow ran on BNY's private digital ledger, and BNY plans digital cash, tokenised deposits and extended triparty hours reaching European and Asian time zones next year.
An overnight repo lasts about a day, so settling in minutes instead of T+1 removes a delay as long as the loan itself.
