Globally, BlackRock manages $10 trillion in assets. The launch of BUIDL (BlackRock USD Institutional Digital Liquidity Fund) in March 2024 saw less than $1 billion worth of tokenized US Treasury bonds; by January 2026, the market had exceeded $10 billion — a direct result of overnight institutional capital following BlackRock from their public/regulated investment in blockchain-based financial systems. Instead of merely being involved with this expansion, BUIDL serves as a primary driver for its continued growth and has allowed the entire Treasury Bond market to expand around itself. As holders of BUIDL shares continue to benefit from a consistent<a href="https://www.prnewswire.com/news-releases/blackrock-usd-institutional-digital-liquidity-fund-buidl-tokenized-by-securitize-surpasses-1b-in-aum-302401480.html" rel="noopener noreferrer" target="_blank"> </a><a href="https://www.prnewswire.com/news-releases/blackrock-usd-institutional-digital-liquidity-fund-buidl-tokenized-by-securitize-surpasses-1b-in-aum-302401480.html" rel="noopener noreferrer" target="_blank">$1.00 NAV per share</a> (total holding value of $2.24 billion), daily interest accruals are credited to their wallet automatically without need for a third party intermediary and without any delay — no waiting for closing windows, etc… as all transactions settle immediately. The operational difference between the timeframe for institutions to settle cash transactions (both of which take two business days from the date of request to the time that cash is available to the institution) and the yield differential is greater than the yield differential.<h2>What BUIDL Actually Is and How It Runs</h2>BUIDL is a regulated fund with its establishment in the British Virgin Islands; however, only US-qualified purchasers can participate. A purchaser must have $5 million or more in investable assets to invest in the fund using USDC. Therefore, limiting the ability to invest in the fund via USDC to those who qualify as US-qualified purchasers. The fund has no retail access. The fund is designed to provide institutions with a way to access institutional asset classes via a tokenized structure. Securitize's primary purpose is to enable the tokenization of assets and to provide transfer agency services.<a href="https://www.coindesk.com/business/2025/11/14/blackrock-s-usd2-5b-tokenized-fund-gets-listed-as-collateral-on-binance-expands-to-bnb-chain" rel="noopener noreferrer" target="_blank"> </a><a href="https://www.coindesk.com/business/2025/11/14/blackrock-s-usd2-5b-tokenized-fund-gets-listed-as-collateral-on-binance-expands-to-bnb-chain" rel="noopener noreferrer" target="_blank">Custody services for the assets are provided by the Bank of New York Mellon</a>. The assets in which the fund primarily invests are repurchase agreements secured by Treasuries or T-bills with short-term maturities. Every aspect of the fund's structure is audited and subject to regulation; this is one of the key reasons why BlackRock chose to adopt this structure, as it allows the institutions which invest in the fund to benefit from the efficiencies of blockchain technology without having to trust a blockchain. Instead, the structure provides institutions with an opportunity to participate in institutional asset classes through their existing relationships they have with their respective counterparties (BlackRock, BNY Mellon and Securitize). The term "BUIDL" was coined by Ethereum and initiated an entirely new marketplace, with the operating systems that all the other networks (Solana, Polygon, Optimism, Arbitrum, Avalanche, Aptos, and BNB Chain) operate on behalf of their users. As a result,<a href="https://wormhole.com/blog/blackrock-and-securitize-expand-buidl-to-bnb-chain-with-interoperability" rel="noopener noreferrer" target="_blank"> </a><a href="https://wormhole.com/blog/blackrock-and-securitize-expand-buidl-to-bnb-chain-with-interoperability" rel="noopener noreferrer" target="_blank">Wormhole enables the seamless transmission of tokens</a> from one network to another, regardless of which network a token holder utilizes. Furthermore, in addition to its BNB Chain extension, Binance has approved the BUIDL token as collateral for the trading and margin of fund targets on multiple major exchanges. <h2>Collateral Is the Real Product</h2> The yield — BUIDL is a vital provider of collateral utility that acts as a source of institutional collateral across all major cryptocurrencies. This means that platforms such as<a href="https://www.ccn.com/education/crypto/blackrock-buidl-fund-tokenized-money-markets-explained/" rel="noopener noreferrer" target="_blank"> </a><a href="https://www.ccn.com/education/crypto/blackrock-buidl-fund-tokenized-money-markets-explained/" rel="noopener noreferrer" target="_blank">Deribit, Crypto.com, and Binance allow customers to use BUIDL as collateral</a> for trades. We have already seen an example of the largest financial institution in the world using today's tokenized US Treasuries for collateralizing a derivatives transaction. Thus, the largest banks have determined that on-chain collateral rails serving as a source of collateral for derivative contracts are compliant with the bank's regulatory framework. According to Robbie Mitchnick (Global Head of Digital Assets at BlackRock), "The use of BUIDL as a form of collateral across the entire digital landscape will introduce core elements of traditional finance into the on-chain financial ecosystem." This is not speculation. This is a fact. The inception of DeFi took place the minute that<a href="https://www.coindesk.com/markets/2026/02/11/blackrock-takes-first-defi-step-lists-buidl-on-uniswap-as-uni-jumps-25" rel="noopener noreferrer" target="_blank"> </a><a href="https://www.coindesk.com/markets/2026/02/11/blackrock-takes-first-defi-step-lists-buidl-on-uniswap-as-uni-jumps-25" rel="noopener noreferrer" target="_blank">BUIDL began to integrate with Uniswap</a>, the first decentralized exchange, which had no institutional compliance officers who would have approved that integration as being compliant two years earlier. Circle's smart contracts facilitate real-time conversions of BUIDL to USDC at any time without regard to business hours (or a redemption window) and allow users to rely on the stable nature of the yield on US Treasuries for three-to-six months after converting to USD. <h2>The Market Position Shift Nobody Expected</h2> BUIDL was the largest participant in the tokenized Treasury market at the end of 2025, with a market share of over 40%. Value-wise, the<a href="https://onchaintreasury.org/2026/01/23/tokenized-us-treasuries-for-dao-treasuries-usyc-vs-buidl-tvl-yields-and-integration-2026/" rel="noopener noreferrer" target="_blank"> </a><a href="https://onchaintreasury.org/2026/01/23/tokenized-us-treasuries-for-dao-treasuries-usyc-vs-buidl-tvl-yields-and-integration-2026/" rel="noopener noreferrer" target="_blank">USYC token, on a gross basis, just passed BUIDL</a> (by about $5 million) when comparing their total AUM in January 2026. The structural differences between the two (USYC accumulating yield vs. BUIDL distributing yield) are much more important than the actual size of the gap in their AUM.USYC typically has an accumulated yield structure, which is much easier to use in automation systems (e.g., margin, derivative clearing, and DeFi lending) without having to maintain a separate yield payment and without a separate payout event to reconcile its collateral value. As a result, the value of the collateral increases, leading to a rapid growth of USYC,<a href="https://uk.finance.yahoo.com/news/defi-protocol-usuals-surge-catapults-201630335.html" rel="noopener noreferrer" target="_blank"> </a>from less than $500 million in mid-2025 to briefly exceeding BUIDL's AUM in January 2026, due to this mechanical advantage rather than brand recognition. <h2>What the BNB Chain Move Signals</h2> BUIDL's expansion onto BNB Chain is a clear indication of the fund's future direction. Other Layer 2 networks, along with Ethereum, are not positioned to monetize the high volume of retail and semi-institutional demand for DeFi on the BNB chain. The intention in bringing BUIDL to this network is not for yield seekers, but to create more venues, counterparties, and capital that can all utilize BUIDL as a cash equivalent to one another, without needing to change networks. We want to create a wider aggregate surface area of collateral. In 2026,<a href="https://fortune.com/2025/11/14/blackrocks-2-5-billion-tokenized-money-market-fund-gets-boost-with-binance-tie-up/" rel="noopener noreferrer" target="_blank"> </a>Morgan Stanley plans to roll out a tokenized asset wallet. In real time, Goldman Sachs will actually be utilizing tokenized Treasuries in their derivative trading. Based on their analysis, McKinsey estimates $2 trillion in tokenization will occur by 2030. BlackRock established the benchmark RWA product, and the surrounding market is now rapidly growing.BUIDL is no longer simply a test; it is now a working model for successfully implementing institutional RWA tokenization.

BlackRock’s BUIDL drives $10B+ in tokenized Treasuries, enabling instant settlement, institutional collateral use, and cross-chain integration across major blockchains.
