BlackRock's tokenized treasury bond fund BUIDL attracted US$52 million in a single day
BlackRock's tokenized treasury bond fund BUIDL (BlackRock Dollar Institutional Digital Liquidity Fund) recorded a new capital inflow of US$52 million within 24 hours, further consolidating its position as one of the leading forces in the chain's fixed income sector.
Fund specifically built for institutional scale
BUIDL is a tokenized money market fund launched in March 2024, with Securitize acting as the transfer agent. Its earnings come from U.S. Treasury bonds, repurchase agreements and cash held by Bank of New York Mellon. Each BUIDL token has a target net value of US$1 and gains are accumulated daily through a compound interest mechanism. The fund is limited to qualified investors only, with a minimum subscription amount of US$5 million.
In mid-July 2026, BlackRock's BUIDL Fund added US$436 million in assets to the Avalanche blockchain in the previous week, a weekly increase of 105%, bringing its holdings on Avalanche to more than US$900 million, pushing BUIDL's total asset management across all networks to approximately US$2.87 billion.
Securitize, which manages the fund as a transfer agent, was listed on the New York Stock Exchange in July 2026 under the ticker symbol "SECZ" and manages a total locked value of more than US$3 billion through BUIDL. Since its inception, the fund has distributed more than $100 million in dividends, fully demonstrating the actual benefits this model can generate. Unlike speculative crypto tokens, BUIDL is a regulated investment product that provides treasury bonds with current annualized yields of approximately 4.5% to 5.0%, and has on-chain accessibility.
Institutional momentum in fast-growing markets
BUIDL leads the broader category of tokenized U.S. Treasuries, which has grown from approximately US$1 billion in early 2024 to more than US$15 billion in the second quarter of 2026. This success demonstrates that institutional demand for on-chain income-based dollar instruments is not theoretical, but substantial and growing.
In November 2025, the integration with BNB Chain and Binance's approval of BUIDL as over-the-counter collateral further enhanced its effectiveness and liquidity, allowing institutional traders to use tokenized treasury bonds for margin trading, thereby connecting traditional fixed income to the active crypto market.
BlackRock has also submitted two new tokenized fund applications with the Securities and Exchange Commission to supplement BUIDL, including a tokenized version of BlackRock Selected Treasury Liquidity Fund (BSTBL) and BlackRock's Daily Reinvestment Stabilizer Reserve Facility (BRSRV), a blockchain-native tokenized money market fund. The moves suggest BlackRock views tokenized fixed income as a permanent part of its product line rather than an experiment.
