BNY lends cash to Citadel Securities against a tokenized Treasury, and names no sum

BNY has used a tokenized US government bond in the market where Wall Street borrows overnight against bonds, and lent the cash itself. Citadel Securities, the market-making firm, bought a two-year Treasury note through BNY on Tradeweb, an electronic bond marketplace. BNY recorded a token representing the note on its own private digital ledger. It says the purchase settled within minutes, rather than the next business day that is usual for Treasuries. Citadel Securities then pledged the note in an overnight triparty repo, and BNY provided the cash. A repo is a short loan secured on a bond; in a triparty repo, a third party holds and values the bond while the loan runs.

BNY, which announced the trade on 13 October, calls it the first use of tokenized assets on a major triparty repo platform. Its position is what gives the claim weight. Ledger Insights, a trade publication, notes that BNY has been the only major US triparty agent since JPMorgan left the business in 2019, and that it clears around $24trn a day. This is where dealers fund their holdings of government bonds overnight, so a bond that settles in minutes can be turned into cash sooner. "Efficient movement of high-quality collateral is fundamental to well-functioning markets," said Dan Doherty, who leads digital-asset operations at Citadel Securities.

Much of the trade is undisclosed. The release names no ledger, no value for the note, no repo rate, no loan amount and no trade date, and nothing in it says the cash moved as a token. Both sides of the trade also stayed inside one bank. BNY was the triparty agent, the keeper of the ledger and the lender, which Ledger Insights calls unusual: normally the agent sits between a dealer and an outside lender such as a money market fund. If buyer and seller are both BNY clients, it argues, the trade could settle in real time across BNY's own books with or without a blockchain. BNY already runs repos lasting part of a day and has settled Treasuries after hours by conventional means. "So the interesting question is not what the trade did but why BNY is bothering with tokens at all," Ledger Insights wrote.

BNY's own answer is that tokens and longer hours go together. It plans to add digital cash and tokenized deposits for settling trades on a ledger. It also expects to keep its conventional settlement systems open longer, reaching into European and Asian trading hours next year. In July the bank said it would test tokenized Treasuries on its own blockchain by the end of 2026, as a step towards settling them around the clock. This is the first such trade it has announced. "This transaction shows how tokenized collateral can help reduce friction while still using the trusted market structure participants rely on," said Brian Ruane, who runs clearance and collateral management at BNY. Until BNY says the cash moved on a ledger too, only the bond side of the trade is known to have been tokenized.
