BlackRock launches 2 tokenized money market funds for stablecoin reserves

BlackRock launched two tokenized money market products Aug. 3, adding BSTBL on Ethereum and BRSRV across multiple blockchains, both designed as eligible reserve assets for U.S. stablecoin issuers under the GENIUS Act.

"Cash remains a foundational building block for investors, corporations, and financial institutions," Jon Steel, Global Head of Product and Platform for BlackRock's Cash Management business, said. "As demand grows for high-quality reserve assets to support stablecoins and other tokenized financial products, these funds provide clients with additional choice in how they access and use money market fund investment solutions across traditional and digital markets."

BSTBL issues a tokenized share class on Ethereum of the existing BlackRock Select Treasury Based Liquidity Fund, with BNY serving as transfer agent and tokenization provider. BRSRV is a newly created fund featuring daily dividend reinvestment and multi-blockchain accessibility, with Securitize handling token issuance and investor recordkeeping. Both funds invest in cash, short-term U.S. Treasury securities, and overnight repurchase agreements backed by Treasuries, seeking current income consistent with liquidity and stability of principal. U.S. money market funds have grown to more than $8.4 trillion in assets, and BlackRock's Cash Management Group oversees nearly $1.073 trillion in cash strategies for corporations, banks, foundations, insurance companies, and public funds.

The launch deepens BlackRock's push into tokenized finance as the firm seeks to become the stablecoin reserve manager of choice. CFO Martin Small said during the Q2 2026 earnings call that BlackRock already manages $60 billion of reserves for Circle, representing about a quarter of the $300 billion stablecoin market.

GENIUS Act compliance shapes fund design

The investment strategy of both funds is structured to make them "eligible reserve assets" for permitted U.S. payment stablecoin issuers under the Guiding and Establishing National Innovation for U.S. Stablecoins Act, enacted in July 2025. Stablecoins are digital tokens pegged to fiat currency, and their issuers must hold high-quality liquid assets as reserves under the new federal framework — a structure that parallels but is distinct from traditional bank reserve requirements. However, aspects of the GENIUS Act remain subject to interpretation, and federal regulators including the OCC and the U.S. Department of the Treasury are still developing implementing standards, according to BlackRock's prospectus disclosures. Changes in those standards could require the funds to adjust portfolio holdings or modify operational practices.

Tokenized cash race intensifies

BlackRock's expansion follows its SEC filing in May 2026 for the new products. The asset manager joins a growing field of tokenized money market fund issuers competing for stablecoin reserve business, including firms that have already established tokenized Treasury products on public blockchains. With $8.4 trillion in U.S. money market fund assets and rising demand for compliant reserve vehicles, the tokenized cash market represents a significant growth opportunity for asset managers bridging traditional finance and digital assets.

The launch shows that major asset managers view tokenized money market funds as a bridge between traditional finance and digital assets. As stablecoin issuers face GENIUS Act reserve requirements, demand for compliant, high-quality reserve vehicles is expected to grow, potentially driving further capital into tokenized Treasury products on Ethereum and other blockchains. For BlackRock, the products extend its existing $60 billion stablecoin reserve management business into a tokenized format that can serve a broader range of digital asset use cases.
