State Street launches GENIUS Act-aligned SSCXX money market fund

State Street Investment Management launched the State Street Stablecoin Reserves Money Market Fund, ticker SSCXX, on June 17, 2026. The fund is registered under Rule 2a-7 and is designed for stablecoin issuers. State Street Bank and Trust Company and Anchorage Digital are listed as initial investors.

SSCXX holds U.S. Treasury securities and other short-term government assets. The portfolio composition is structured to meet the GENIUS Act’s reserve requirements for permitted payment stablecoins, which specify eligible high-quality liquid assets.

Rule 2a-7 funds operate under the Investment Company Act of 1940 and are commonly used in institutional cash management. The GENIUS Act permits money market funds registered under that framework to qualify as reserve assets for stablecoin issuance.

Federal regulators have proposed a liquidity schedule for permitted payment stablecoins that would require at least 10% of outstanding coins to be redeemable the same business day and 30% within five business days. SSCXX provides a Treasury-backed, instantly redeemable vehicle that stablecoin issuers can hold as backing assets.

State Street Investment Management manages about $4.7 trillion in assets. Anchorage Digital is the only OCC-chartered federally regulated crypto bank in the United States. Both institutions are listed as initial investors, and State Street Bank and Trust Company is also named.

SSCXX is intended for the issuer side of the stablecoin market rather than for retail holders or tokenized on-chain yield products. The fund is available to licensed stablecoin issuers preparing to meet GENIUS Act requirements ahead of the July 18, 2026 federal rulemaking deadline.
