In a bold move signaling the growing convergence of traditional finance and blockchain technology, BlackRock, the world’s largest asset manager, has filed with the U.S. Securities and Exchange Commission (SEC) to introduce a blockchain-enabled digital share class, termed “DLT Shares,” for its $150 billion Treasury Trust Fund. This filing, announced on April 30, 2025, underscores BlackRock’s commitment to leveraging distributed ledger technology (DLT) to revolutionize financial infrastructure, aligning with CEO Larry Fink’s vision of tokenization as the future of investing.A Strategic Step Toward TokenizationThe proposed DLT Shares will utilize blockchain technology solely for recordkeeping, not for holding cryptocurrencies within the fund’s portfolio. Partnering with BNY Mellon, BlackRock aims to streamline ownership tracking for its Treasury Trust Fund, a money market fund designed to maintain a stable $1 per share value by investing in highly liquid assets like cash and short-term government securities. The initiative targets institutional investors, requiring a minimum investment of $3 million, with no minimums on subsequent purchases.This move builds on BlackRock’s prior forays into blockchain. The firm’s USD Institutional Digital Liquidity Fund (BUIDL), launched in March 2024 with Securitize, has already amassed over $1.7 billion in assets, demonstrating BlackRock’s growing expertise in tokenizing real-world assets (RWAs). The BUIDL fund, seeded with $100 million in USDC stablecoin on the Ethereum network, marked a significant milestone in bringing traditional assets onto blockchain rails. The expansion of BUIDL to the Solana blockchain further highlights BlackRock’s platform-agnostic approach to tokenization.Why Blockchain?BlackRock’s embrace of blockchain for the DLT Shares reflects broader industry trends toward tokenization, which promises faster settlements, enhanced transparency, and reduced operational costs. By recording share ownership on a blockchain, BlackRock aims to eliminate delays associated with traditional financial systems, enabling near-instantaneous transactions and reinvestment of capital. As Larry Fink noted in his 2025 annual letter to investors, tokenization could “revolutionize” investing by enabling 24-hour markets and compressing settlement times from days to seconds.The Treasury Trust Fund’s DLT Shares could serve as a testing ground for broader applications, potentially laying the foundation for digital currencies or cash transactions in the future. However, Fink has emphasized a critical challenge: the lack of a coordinated digital identity verification system. Without robust identity checks, tokenized assets risk fraud and regulatory hurdles, a concern BlackRock is likely addressing in its SEC filing.Regulatory and Market ImplicationsThe SEC filing is preliminary and awaits approval, a process that could shape the regulatory landscape for tokenized assets. BlackRock’s influence as a $9 trillion asset manager lends weight to its proposal, potentially pressuring regulators to clarify rules around blockchain-based financial products. The involvement of BNY Mellon, a major custodian bank, further signals institutional confidence in blockchain’s reliability for high-stakes financial operations.BlackRock’s push aligns with a broader wave of tokenization efforts. Competitors like JP Morgan, State Street, and Franklin Templeton are also exploring blockchain for tokenized funds, while Libre recently tokenized $500 million of Telegram’s debt on the TON blockchain. The SEC’s response to BlackRock’s filing could set a precedent, either accelerating or tempering the adoption of blockchain in traditional finance.
