BlackRock has expanded its tokenized asset portfolio by launching two new money market funds, BSTBL and BRSRV, specifically designed to serve as reserve assets for U.S. stablecoin issuers. These products are structured to comply with the U.S. federal stablecoin law, known as the GENIUS Act, which was enacted in July 2025. BSTBL functions as a tokenized share class of the existing Select Treasury Based Liquidity Fund and operates on the Ethereum blockchain, allowing for peer-to-peer transfers between approved wallets. BRSRV is a newly established fund for institutional investors that supports multi-chain functionality and features automated daily dividend reinvestment. This strategic move follows the success of BlackRock's BUIDL fund, which currently manages over $2.6 billion in assets and remains the largest tokenized Treasury fund in the market. By providing compliant reserve solutions, BlackRock is positioning itself to capture the growing demand for institutional-grade collateral in the stablecoin sector. This development underscores the increasing integration of traditional financial instruments with blockchain infrastructure to meet evolving regulatory standards.
BlackRock is the world's largest asset manager, overseeing trillions of dollars in traditional financial products. The firm has recently pivoted toward blockchain technology by tokenizing money market funds, which allow investors to hold shares on-chain while maintaining exposure to high-quality, liquid assets like U.S. Treasuries.
