BlackRock Adds Third Onchain Fund as Asset Managers Eye Stablecoin Reserves

What happened

BlackRock added a third on‑chain fund, tokenizing an existing six‑point‑one‑billion‑dollar Treasury fund (BSTBL) and launching a new fund (BRSRV), giving it the widest tokenized cash lineup among rivals racing to bank stablecoin reserves under the GENIUS Act.

Confirmed

Global impact / market context

Tokenized cash lets investors hold Treasury assets on a blockchain, supporting the build‑up of stablecoin reserves and putting BlackRock ahead in the emerging regulated on‑chain finance space.

Analyst inference

Asset managers are racing to secure stablecoin reserves as the GENIUS Act—a law encouraging on‑chain cash holdings for financial stability—promotes tokenized Treasury products, which could shift capital toward digital cash and affect crypto‑market liquidity.

Analyst inference

What to watch

1. Implementation of the GENIUS Act – watch how regulators apply this law and whether it creates mandatory stablecoin reserve requirements for asset managers. Analyst inference
2. Rival tokenized cash offerings – monitor other firms launching similar on‑chain Treasury funds, which could erode BlackRock’s market‑share advantage. Analyst inference
3. Investor inflows into BSTBL and BRSRV – track demand for these tokenized Treasury products as a gauge of appetite for digital cash assets. Analyst inference
