BlackRock, DTCC Push Tokenized Treasury Yield Onchain

Tokenized Treasury funds have grown from an experiment into a $17 billion market, CoinDesk Research reported in June 2026. The question for traders and treasurers is how the yield actually moves from T-bills to a wallet, and what gets lost along the way.

The rate starts in short-dated U.S. bills and overnight repo. When the Fed adjusts rates, those instruments reprice within days. The gross yield then passes through management fees, custody costs, and the token's distribution mechanism before it reaches the holder. Two wrappers holding similar paper can pay out very differently onchain.

BlackRock's BUIDL fund now offers a $100 million liquidity facility that lets eligible holders exchange into USDC and other tokenized instruments outside traditional market hours, CoinDesk reported in late June. The facility also plans to connect a third-party yield token into BlackRock's Aladdin risk stack.

Tradeweb facilitated a live onchain Treasury transaction on the Canton Network at the start of July, where Franklin Templeton delivered a tokenized U.S. Treasury security to Virtu in exchange for tokenized cash called USDCx, the company said in a press release.

Two weeks later, DTCC said it had converted DTC-held securities into tokenized representations and ran genuine production trades including delivery-versus-payment for Treasuries and repo, with more than 30 firms participating.

These experiments matter because they compress settlement time and lower counterparty slippage. When the cash leg and securities leg settle on the same ledger, funds stop sitting idle waiting for wires.

The mechanics of yield distribution vary by product. Some tokenized fund shares accrue yield into net asset value, so a single token becomes redeemable for more dollars over time. Others use rebasing, which adds units to a holder's balance. A rebase token works smoothly in lending protocols, while a pure NAV-drifting share may be simpler from a tax perspective in some jurisdictions but not every onchain protocol handles it cleanly.

BNY Mellon has told clients it plans to issue tokenized Treasuries and run pilot trades on its private chain by year end, and aims to support 24-7 settlement for both conventional and tokenized Treasuries in 2027, Bloomberg News reported.

CoinDesk Research's June 2026 Stablecoins & Tokenized Assets report estimated total tokenized real-world assets at roughly $30.1 billion, with tokenized Treasuries leading at about $17 billion. That number remains small next to the overall Treasury market, but the infrastructure is catching up.

DTCC's production session with Treasury DvP and repo involving over 30 firms signals where the pipes are going, the company said. Tradeweb's Canton transaction and BlackRock's after-hours swap line show that liquidity bridges between tokenized funds and stablecoins are taking shape.

For a trader weighing one wrapper over another, the checklist includes how yield is computed, how often the token updates NAV onchain, and whether the product has explicit after-hours swap arrangements or multiple primary dealers making two-way markets. Those operational details determine whether the headline APY holds up when the market moves on a Sunday evening.
