The world’s largest asset manager introduces two blockchain-based money market funds compliant with US stablecoin reserve rules.
BlackRock has launched two tokenized money market funds aimed at serving as reserve assets for stablecoins under the US GENIUS Act. The products expand the firm’s presence in the tokenized Treasury market, targeting institutional investors and digital asset use cases.
The first fund, BSTBL, is a tokenized share class of an existing Treasury-based liquidity fund on Ethereum, allowing transfers between approved wallets. The second, BRSRV, is a new fund supporting multiple blockchains and automatically reinvests daily dividends. Both are structured to meet regulatory requirements for stablecoin reserves.
The move follows the July 2025 enactment of the GENIUS Act, which sets federal standards for stablecoin issuers. BlackRock’s funds invest in cash, short-term Treasurys, and Treasury-backed repurchase agreements, aligning with regulatory expectations for reserve assets.
