State Street Investment Management has officially joined the stablecoin reserve race with a new fund designed to manage stablecoin assets today. The top investment financing firmβs new money market fund will be purely for issuers operating under the GENIUS Actβs reserve requirements.
The State Street Stablecoin Reserves Money Market Fund (ticker: SSCXX) has been launched as a registered investment vehicle for direct cash holdings and short-term U.S. Treasuries maturing within 93 days. The fund will also hold overnight repurchase agreements collateralized by those Treasuries, according to the firmβs press release.
Anchorage Digital is the fundβs first external backer, operating the only federally chartered crypto bank in the United States. State Street Bank and Trust Company are also financial facilitators, according to the firmβs investor relations page.
State Street SSCXX holdings
State Streetβs new money market fund has launched with about $121 million in assets under management, a 3.51% yield, and a 0.18% net expense ratio on its Capital Class, carrying a $15 million minimum investment.
The fund targets a stable $1.00 net asset value and currently carries a three-day weighted average maturity, well inside the 60-day regulatory cap, with investment access available to only issuers under the GENIUS Actβs oversight.
This comes with tradeoffs, as the fund carries no FDIC insurance and no principal guarantee from State Street, per the firmβs own risk disclosures. The restricted asset mix could also compress yields when compared to other government or prime money market alternatives.
The launch follows State Streetβs recent introduction of SWEEP, a tokenized liquidity product built with Galaxy Digital that enables around-the-clock cash management on the blockchain. Together, the two products form the core of State Streetβs recent push into tokenized money infrastructure.
Why does a dedicated stablecoin fund matter?
The GENIUS Act, signed into law in July 2025, gave stablecoin issuers their first federal framework in the United States. The act requires one-to-one backing for stablecoins with high-quality liquid assets and explicitly allows registered 1940 Act money market funds to qualify as reserve vehicles.
The lucid understanding granted by the act has helped to create a product in stablecoin reserve management. BlackRock already manages a large share of the Treasury portfolio behind Circleβs almost $75 billion USDC. Franklin Templeton, Fidelity, JPMorgan, Goldman Sachs, and BNY have all rolled out competing products targeting the same pool of assets over the past year.
βFor more than 40 years, the cash management business of State Street Investment Management has delivered liquidity solutions to the worldβs largest and most sophisticated institutional investors,β said Yie-Hsin Hung, president and CEO of State Street Investment Management, in the companyβs announcement. βWeβre excited to partner with Anchorage Digital to bring these capabilities to the digital assets space.β
Nathan McCauley, co-founder and CEO of Anchorage Digital, framed the partnership around infrastructure credibility. βStablecoins are quickly becoming core financial infrastructure, making the quality and management of their reserves critically important,β McCauley said in the same release.
State Street pointed to Citi Institute research from September 2025 projecting that global stablecoin issuance could reach $1.9 trillion to $4 trillion by 2030, according to the firmβs press release. These projections, if realized, would lead to the growth of reserve assets generating management fees by multiples from todayβs current levels.
