BNY and Citadel Securities Complete First Tokenized Treasury Triparty Repo

The significance is less the tokenization itself than where it happened: triparty repo is core plumbing, not a sandbox, and using a tokenized Treasury as collateral there tests whether distributed ledgers can compress settlement from a full day to minutes inside existing custody and financing rails. If it holds up, the pressure point shifts to digital cash and tokenized deposits, which BNY flags as next — collateral can move fast only if the cash leg can too. Whether this stays a single flagship trade or becomes routine triparty practice is the open question.
