BNY tests tokenized Treasury in repo

BNY, one of the world's largest custody banks, has completed a repurchase agreement with Citadel Securities in which a tokenized US Treasury note was used as collateral. The bank says it is the first use of tokenized assets on a major triparty repo platform.

What happened

Citadel Securities bought a two-year US Treasury note through BNY on the Tradeweb trading platform. The note was then converted into a tokenized form on BNY's private digital ledger and settled within minutes, rather than on the usual next-day (T+1) cycle. Citadel Securities then pledged the tokenized note as overnight collateral, and BNY provided cash in return. The size of the trade was not disclosed.

A quick guide to repo

A repurchase agreement, or repo, is a short-term loan backed by securities. One party hands over bonds and receives cash, agreeing to buy the bonds back later, often the next day, at a slightly higher price. In a triparty repo, a bank such as BNY sits in the middle and handles settlement, valuation and collateral management for both sides. Repo is one of the main ways dealers fund their positions, and US government bonds are the most common collateral.

Why speed matters

When a dealer buys a bond, it normally has to wait for settlement before it can reuse that bond to raise cash. That gap ties up balance sheet. By settling the tokenized note within minutes, the test showed how a newly bought bond could be put to work as collateral almost immediately. This idea, often called collateral mobility, is one of the most practical arguments for tokenizing traditional assets.

Notably, the trade ran through BNY's existing triparty platform rather than a separate blockchain venue. That suggests large incumbents want to bring tokenization into the infrastructure markets already use, instead of building parallel systems.

The wider tokenization trend

Tokenized versions of US government debt have become one of the fastest-growing corners of digital finance. Asset managers have launched tokenized Treasury and money market funds, and exchanges and brokers have started to accept some of them as collateral. What has been missing is proof that these instruments can work inside the core funding markets that large dealers use every day. A tokenized Treasury moving through a major bank's existing repo platform is a step in that direction.

It is also a test of whether a token can carry the same legal and operational certainty as the bond it represents. For repo to work, the cash lender must be confident it can take and sell the collateral if the borrower fails. Running the trade on an established triparty platform, with familiar legal agreements, helps answer that question.

Why it matters for payments

Fast, always-available settlement is the common thread between tokenized securities and digital payments. As banks connect tokenized assets with digital cash, the same rails could eventually let money and securities move together in real time, which would lower costs and settlement risk across the financial system.

What to watch next

BNY says it plans to add digital cash and tokenized deposit capabilities for on-chain settlement, and to extend operating hours into European and Asian trading windows next year to support markets that run around the clock. It has not given a timeline for opening the workflow to a wider group of clients.
