State Street Enters Stablecoin Reserve Race, Joins Blackrock and Goldman With New Genius Act Fund

State Street Investment Management launched a dedicated money market fund for stablecoin issuers on June 8, 2026, becoming the fourth major financial institution to target one of Wall Street’s fastest-growing reserve management niches.

• Key Takeaways:
• • State Street launched the SSCXX money market fund on June 8, 2026, with $121M in early AUM and a 3.51% yield.
• • The GENIUS Act, signed July 2025, created the federal reserve framework that made this product category possible for stablecoin issuers.
• • Anchorage Digital joined as a seed investor, pairing its federally chartered crypto bank infrastructure with State Street’s cash management platform.

Fund Basics

The State Street Stablecoin Reserves Money Market Fund operates under SEC Rule 2a-7 and holds only assets eligible under the GENIUS Act: short-term U.S. Treasuries maturing in 93 days or less, overnight repurchase agreements collateralized by those Treasuries, and cash. It targets a stable $1.00 net asset value and currently carries a 3-day weighted average maturity, well below the 60-day regulatory maximum.

According to the financial giant’s release, the fund launched with approximately $121 million in assets under management. It yields roughly 3.51% and charges a 0.18% net expense ratio on the Capital Class (ticker: SSCXX). The minimum investment for that share class is $15 million.

Why It Exists

The GENIUS Act, signed into law in July 2025, established the first comprehensive federal framework for payment stablecoins in the United States. It requires issuers to back outstanding stablecoins one-to-one with high-quality liquid assets and explicitly permits registered 1940 Act money market funds to serve as qualifying reserve vehicles.

That regulatory clarity opened the door for firms like State Street to design products purpose-built for stablecoin issuers, which need reserve assets that are safe, liquid, and compliant.

Market Context

The stablecoin market sits at approximately $300 to $315 billion in total market capitalization as of mid-June 2026. Tether holds roughly $186 to $188 billion of that figure, while USDC accounts for about $75 billion. Together, the two dominate roughly 85 to 90% of the market.

Projections from the Citi Institute put global stablecoin issuance between $1.9 trillion and $4 trillion by 2030, a figure State Street cited in its launch announcement.

Key Partnerships

State Street Bank and Trust Company and Anchorage Digital serve as seed investors. Anchorage Digital holds the first federally chartered crypto bank license in the United States and offers stablecoin issuance, custody, and settlement infrastructure to institutions.

“ Stablecoins are quickly becoming core financial infrastructure, making the quality and management of their reserves critically important,” said Nathan McCauley, co-founder and CEO of Anchorage Digital.

Yie-Hsin Hung, president and CEO of State Street Investment Management, pointed to the firm’s four decades of cash management experience as the foundation for the product. “We’re excited to partner with Anchorage Digital to bring these capabilities to the digital assets space,” Hung added.

Competitive Position

State Street enters behind Blackrock, which launched the Circle Treasury Reserves fund in partnership with Circle, and Goldman Sachs and BNY, which also launched GENIUS Act-aligned reserve vehicles earlier in 2026. BNY’s fund, the Dreyfus Stablecoin Reserves Fund, has positioned itself on operational simplicity and institutional familiarity.

The fund connects to State Street’s broader digital asset strategy, which also includes the State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP), a tokenized cash management product that runs around the clock via stablecoin rails.

Risks to Watch

Assets in the fund are expected to move with stablecoin minting and redemption cycles. A depeg event or period of rapid stablecoin redemptions could trigger sharp outflows and force the fund to sell assets at unfavorable prices. The fund carries no FDIC insurance and no guarantee from State Street against loss of principal.

The restricted investment universe, limited to GENIUS-eligible short Treasuries and repos, may also compress yields relative to broader government or prime money market funds.
