State Street Investment Management has launched the State Street Stablecoin Reserves Money Market Fund, a government money market fund aimed at payment stablecoin issuers and other institutional cash-reserve managers.

The product is positioned around the reserve-asset rules created by the GENIUS Act framework. In its SEC filing, State Street says the fund invests in assets that payment stablecoin issuers are permitted to hold, including short-dated U.S. Treasury bills, notes and bonds, repurchase agreements secured by Treasury obligations, and other eligible investments. The filing also says the fund seeks to maintain a stable $1.00 share value.

State Street's public fund page lists the Capital Class ticker as SSCXX and shows an inception date of June 8, 2026. The launch gives stablecoin issuers another large asset-manager option for keeping reserve portfolios in instruments designed for liquidity, principal preservation, and regulatory alignment.

Anchorage Digital said it is participating as a seed investor and framed the product as part of a more institutional reserve-management stack for stablecoin issuers. That matters because reserve management is becoming a competitive layer of stablecoin infrastructure, not just a back-office function.

The cautious read is that this is not a new stablecoin from State Street. It is a fund built for the companies that issue or manage stablecoin reserves. The signal is still important: major asset managers are turning stablecoin legislation into concrete money-market products, adding another bridge between conventional cash management and digital-dollar systems.
