BNY has completed its first triparty repurchase agreement trade on a major platform using tokenized U.S. Treasury collateral, executing the transaction with Citadel Securities. The deal underscores the potential of digital securities to speed up the funding process, although extending the same benefit to other markets remains more difficult.

According to BNY's press release, a two-year Treasury note was purchased by Citadel Securities through BNY on the Tradeweb platform. A tokenized version of the note—a digital representation of the security—was recorded on BNY's private ledger, allowing settlement within minutes instead of the customary T+1 timeline. Citadel then used the token as collateral in an overnight triparty repo, obtaining cash from BNY. In a repurchase agreement, one party sells securities while agreeing to buy them back later, effectively borrowing cash against them; in the triparty version, a third-party agent holds and manages that collateral between the two trading sides. Because overnight trades like this one must be renewed each business day, the speed at which collateral can move between counterparties directly affects how quickly funding can be obtained.

Citadel's Dan Doherty called the deal “a practical use case that shows how tokenized U.S. Treasuries can move from settlement into financing more efficiently.” BNY's Carolyn Weinberg, for her part, pointed to its application “across both settlement and financing.” What made the transaction noteworthy was its implementation on a major triparty platform, rather than the concept of tokenized repo itself.

A milestone, not a first

Tokenized repo was already functioning at a large scale. Broadridge disclosed that it processed $7.5 trillion in September 2026, with an average of $359 billion worth of trades daily. Unlike BNY, Broadridge operates its own distributed ledger repo platform.

The global repo market handles a volume of over $10 trillion every day, which makes settlement delays a costly issue. In traditional transactions, T+1 and T+2 periods are common, while margin adjustments usually occur in batches. “Timing is the root issue,” Callan wrote. Tokenization can help solve these delays by allowing collateral to travel faster, although a single BNY transaction is not enough to prove the case.

Collateral that moves across time zones

In 2027, BNY hopes to expand its Fed-eligible payment settlement methods and triparty operations to Europe and Asia, with digital cash features also in development. Extended operating hours could enable seamless international funding if cash and collateral are able to move together. Because overnight funding has to be renewed within each market's settlement window, the hours during which settlement can occur shape where and when institutions can roll that financing.

The potential scope of tokenized repo is considerable given the size of the underlying markets. According to ICMA, there were around €14.9 trillion in outstanding European repo agreements in the first half of 2026, a figure that indicates market size rather than trading volume. Financial players are already stepping up to provide tokenized financing; Broadridge, for example, has expanded its repo network to operate with G7 securities.

However, the need for quick access to securities is only one of the requirements. Tokenized financing also requires access to digital cash as a means of settlement. BNY has made a notable advance in meeting that condition with the launch of its tokenized deposits in January 2026.

Interoperability, settlement money and systemic questions

BNY's private ledger is only one system. In July 2026, DTCC tokenized DTC-held securities on Besu and Canton, with more than 30 firms participating. Tests included a Treasury repo delivery-versus-payment transaction—in cash and securities exchange simultaneously—and its tokenization service was scheduled for October.

The BIS warns that digital settlement must preserve trust in money and legal finality. Institutions also face fragmented liquidity and cross-ledger risks. The real question is whether these networks can exchange collateral safely at scale.
