Citadel Securities and BNY Complete Tokenized U.S. Treasury Repo Transaction

Citadel Securities uses a tokenized two-year U.S. Treasury note as overnight collateral in a repo transaction with BNY.

Citadel Securities and BNY have completed a tokenized U.S. Treasury repurchase agreement (repo), marking a reported milestone in the use of tokenized financial assets within traditional financial market infrastructure. The transaction involved Citadel Securities using a tokenized Treasury note as overnight collateral in exchange for cash provided by BNY.

According to information shared by Coin Bureau, BNY described the transaction as the first use of tokenized assets on a major triparty repo platform. The development demonstrates how tokenized versions of traditional securities can be incorporated into established collateral and financing arrangements.

How the Tokenized Treasury Transaction Worked

The transaction centered on a two-year U.S. Treasury note purchased through BNY on Tradeweb. Its tokenized version was then settled within minutes, compared with the standard T+1 settlement cycle, which generally refers to settlement one business day after a transaction date.

Following settlement, Citadel Securities used the tokenized note as collateral overnight, while BNY supplied cash in return. The arrangement followed the basic structure of a repo transaction, in which securities are exchanged for cash under an agreement to reverse the transaction at a later date.

The reported settlement speed is a key distinction from the conventional process. Instead of following the standard T+1 cycle, the tokenized note settled within minutes. The transaction therefore illustrates how tokenization can change the settlement process for a traditional financial instrument while retaining its role as collateral in a financing arrangement.

BNY's Role in Tokenized Financial Markets

BNY provided the cash for the overnight transaction and was also involved in the purchase of the underlying two-year Treasury note through Tradeweb. Its reported characterization of the transaction as the first use of tokenized assets on a major triparty repo platform places the deal within the broader effort to integrate digital representations of traditional securities into established financial infrastructure.

In a triparty repo arrangement, a third-party agent helps administer elements of the transaction, including collateral management. The use of a tokenized asset in this setting is significant because it brings tokenization into a core institutional financing process rather than limiting its application to the transfer or trading of digital assets.

The transaction also highlights the distinction between purchasing a traditional security and settling its tokenized representation. The two-year Treasury note was purchased through BNY on Tradeweb, while the tokenized version settled within minutes, according to the information shared by Coin Bureau.

Although the reported transaction establishes a concrete example markets of tokenized collateral being used in an overnight repo, the available information does not specify the transaction's monetary value, the blockchain network involved, or whether the approach will be expanded to additional securities or counterparties.
