BlackRock Tokenizes $2.6B Treasury Reserves Under New Stablecoin Law

Woofun AI reports that BlackRock has introduced BSTBL and BRSRV, two tokenized money market funds engineered to function as compliant reserves for stablecoins under the GENIUS Act.

The first offering, BlackRock Select Treasury Based Liquidity Fund OnChain Shares (BSTBL), operates as a tokenized share class of an existing fund on Ethereum. Eligible investors may transfer these shares between approved wallets while the underlying assets remain invested in cash, short-term US Treasuries, and Treasury-backed overnight repurchase agreements.

Woofun AI data shows the second vehicle, BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV), targets institutional investors across multiple blockchains. This newly created fund automatically reinvests daily dividends and is specifically structured for digital asset use cases, including stablecoin reserve management.

Both products align with the federal stablecoin law enacted in July 2025, reinforcing BlackRock’s dominance in the tokenized Treasury market. This expansion complements the USD Institutional Digital Liquidity Fund (BUIDL), which holds over $2.6 billion in assets.
