BlackRock acelera la tokenización con nuevos fondos onchain ligados al Tesoro de EEUU

BlackRock has expanded its integration of traditional financial instruments into blockchain infrastructure by accelerating the deployment of on-chain funds linked to U.S. Treasury securities. This development focuses on the tokenization of real-world assets (RWA), a process that converts the ownership rights of a financial asset into a digital token on a distributed ledger.

The initiative is centered on the BlackRock USD Institutional Digital Liquidity Fund, known as BUIDL. This fund is hosted on the Ethereum blockchain and allows institutional investors to maintain liquidity while earning yields from U.S. Treasury bills. By moving these assets on-chain, the firm aims to reduce the friction associated with traditional settlement processes and provide a more transparent method of asset tracking.

The shift toward tokenized Treasuries addresses a long-standing inefficiency in the traditional finance sector. Standard U.S. Treasury transactions typically rely on legacy banking systems that require multiple intermediaries and can take several days to settle. In contrast, blockchain-based tokens allow for near-instantaneous settlement and 24/7 availability, removing the dependence on traditional banking hours and manual reconciliation.

The Growth of the Tokenized Asset Market

The segment for tokenized real-world assets has grown significantly, with the total value of the sector now exceeding $30 billion. This growth is driven by a broader trend where traditional financial institutions seek to combine the stability of government-backed securities with the operational efficiency of blockchain technology.

Tokenization enables fractional ownership, allowing investors to hold smaller portions of an asset than would be possible in traditional markets. For institutional players, this increases the granularity of portfolio management and allows for the programmable movement of capital via smart contracts, which are self-executing contracts with the terms of the agreement directly written into code.

BlackRock partnered with Securitize, a digital assets securities platform, to manage the issuance and transfer of the BUIDL tokens. Securitize acts as the transfer agent, ensuring that the digital tokens are issued in compliance with regulatory requirements while maintaining the technical bridge between the fund’s underlying assets and the Ethereum network.

Technical Implications for Institutional Liquidity

The transition to on-chain funds changes how institutional liquidity is managed. In traditional systems, moving funds between different asset classes often requires liquidating positions and waiting for settlement before reinvesting. With tokenized Treasuries, these assets can be used as collateral in other decentralized finance (DeFi) protocols or transferred instantly between institutional wallets.

This interoperability allows for a more dynamic use of capital. For example, an institution can hold its reserves in tokenized U.S. Treasuries to earn a stable yield while simultaneously using those tokens to secure loans or execute trades on a blockchain, without needing to exit the position back into a traditional bank account.

the use of a public blockchain like Ethereum provides a shared, immutable ledger. This reduces the need for third-party audits to verify holdings, as the balance and movement of tokens are visible and verifiable on the network in real time, provided the identities of the holders are managed through permissioned layers.

Competitive and Regulatory Context

BlackRock is not the only major financial entity exploring this space. Other firms, including Franklin Templeton, have previously launched tokenized money market funds. However, the scale of BlackRock’s assets under management provides a significant catalyst for the broader adoption of RWA tokenization across the industry.

The move toward blockchain infrastructure is also a response to evolving regulatory frameworks. By utilizing a permissioned approach—where only verified and KYC-compliant (Know Your Customer) investors can hold tokens—BlackRock maintains the compliance standards required for institutional finance while leveraging the speed of decentralized technology.

The integration of U.S. Treasuries on-chain serves as a primary entry point for other asset classes. If the infrastructure for government bonds proves successful and scalable, the industry is likely to apply the same tokenization models to corporate bonds, real estate, and private equity.

As of May 9, 2026, the focus remains on scaling the capacity of these on-chain funds to handle higher volumes of institutional capital. The goal is to transition the core plumbing of the global financial system from siloed databases to a unified, blockchain-based layer that supports both traditional security and modern efficiency.
