BlackRock's BSTBL fund redefines stablecoin reserves, aligning with the GENIUS Act to drive $4T crypto growth by 2030, blending TradFi with DeFi.
In a bold move signaling the deepening integration of traditional finance and cryptocurrency, BlackRock has unveiled a new money market fund tailored as a reserve vehicle for stablecoin issuers.
As the world's largest asset manager overseeing more than $13.5 trillion in assets, BlackRock's BlackRock Select Treasury Based Liquidity Fund (BSTBL) arrives at a pivotal moment for the $313 billion stablecoin market.
This fund offers a regulatory-compliant solution for parking reserves in high-quality U.S. Treasuries, directly addressing the requirements of the recently enacted GENIUS Act.
With stablecoin issuers already holding over $120 billion in U.S. Treasuries, BSTBL positions BlackRock to enhance liquidity, transparency, and efficiency in the crypto ecosystem.

BlackRock has been steadily expanding its footprint in the digital asset space, recognizing the transformative potential of blockchain and cryptocurrencies. The firm already manages reserves for Circle's USDC stablecoin, one of the leading dollar-pegged tokens.
Earlier initiatives include the launch of the iShares Bitcoin Trust (IBIT) and an Ethereum ETF, which have attracted billions in inflows. BlackRock has also pioneered tokenized funds on the Ethereum blockchain, allowing for real-time asset representation and trading.
The BSTBL fund builds on this foundation, evolving from the existing BlackRock Liquid Federal Trust Fund to specifically cater to stablecoin needs, underscoring BlackRock's ambition to become a dominant player in bridging traditional finance (TradFi) with decentralized finance (DeFi).
The BlackRock Select Treasury Based Liquidity Fund (BSTBL) is structured as a 2a-7 money market fund under the Investment Company Act of 1940, ensuring stability and liquidity.
Its portfolio is 100% allocated to short-term U.S. Treasury securities, such as bills and notes, alongside overnight repurchase agreements (repos) backed by Treasuries.
To optimize for stablecoin issuers, BlackRock has shortened asset maturities, extended trading hours to 5:00 PM Eastern Time, and incorporated later valuation times for global accessibility.
As of October 10, 2025, the fund maintains a net asset value (NAV) of $1.00, with a 7-day SEC yield of 4.06%. Fees include a 0.21% management fee, a 0.10% shareholder servicing fee, and total annual expenses of 0.27% after waivers through June 30, 2026.
A standout feature is its support for tokenization, enabling on-chain representations that facilitate 24/7 real-time settlements. This makes BSTBL particularly attractive for institutional users, including stablecoin giants like Circle and potentially Tether, who require compliant, low-risk reserve management.
The GENIUS Act, signed into law by President Donald Trump in July 2025, marks the first comprehensive U.S. federal framework for stablecoins. It mandates 1:1 backing with cash or short-term U.S. Treasuries, requires monthly third-party audits for reserve verification, and enforces enhanced transparency standards.
Designed to mitigate risks like those seen in past stablecoin depegging events, the Act aims to foster trust and stability in the digital asset market.
BlackRock's BSTBL fund is explicitly crafted to comply with these rules, serving as an approved reserve asset. This regulatory clarity has created a surge in demand for institutional-grade solutions, reducing dependence on unregulated custodians and paving the way for broader adoption by traditional financial players.
BlackRock's entry into stablecoin reserves could catalyze significant growth in the sector, with Citi analysts forecasting stablecoin issuance to balloon from $280 billion to $4 trillion by 2030.
The fund enhances credibility by offering a "safe, liquid, and compliant" option, potentially drawing more institutional capital into crypto. It also boosts liquidity through tokenized settlements, reducing friction in cross-border payments, remittances, and DeFi applications.
However, challenges include adapting to ongoing regulatory shifts and securing widespread adoption beyond partners like Circle.
On X, reactions have been enthusiastic:
- @WhaleInsider highlighted the fund's Genius Act compliance for simplifying custody.
- @StablesLabsHelp praised its role in validating synthetic stablecoins.
- @ThuanGlobal noted BlackRock's focus on proper reserve management.
- Other voices like @Crypto_Potato and @MetaEraHK emphasized the bridge between TradFi and crypto.

This fund exemplifies the convergence of crypto and TradFi, enabling faster innovation in areas like synthetic stablecoins and hybrid models. For investors, it signals maturing infrastructure that could attract trillions in capital, while mitigating risks through regulation.
Opportunities abound in payments and DeFi, but stakeholders must navigate potential hurdles like market volatility and evolving compliance. Overall, BSTBL could accelerate mainstream crypto adoption, fostering a more interconnected financial landscape.
BlackRock's launch of the BSTBL fund under the GENIUS Act framework solidifies its leadership in regulated digital assets, offering stablecoin issuers a robust tool for reserve management.
As the sector eyes explosive growth, this initiative not only enhances stability and liquidity but also invites greater institutional participation.
Looking ahead, widespread adoption could transform stablecoins into a cornerstone of global finance, driving efficiency and innovation across borders.
