Fidelity launches money market fund for stablecoin reserve assets
In brief
- Fidelity launched a money market fund for stablecoin issuers to hold required reserves
- State Street unveiled a similar product days earlier, signaling Wall Street's pivot to reserve management
- Stablecoins have grown to $320 billion, with forecasts projecting $1.9–4 trillion by 2030
- GENIUS Act requires stablecoin issuers to hold reserves in Treasury securities, cash, and money market funds
The reserve-management opportunity
Stablecoins have grown into a roughly $320 billion market, with industry forecasts projecting the sector could expand to between $1.9 trillion and $4 trillion by 2030. That growth has created a structural need: stablecoin issuers must hold reserves that back the tokens in circulation. The GENIUS Act, signed into law last year, established the first federal framework for payment stablecoins and set the rules for what those reserves can contain.
Under the GENIUS Act, stablecoin issuers must hold reserves in cash, short-term Treasury securities and certain government money market funds. Fidelity's new fund fits squarely into that mandate. The fund will invest in U.S. Treasury bills, notes and bonds with maturities of 93 days or less, cash, overnight repurchase agreements backed by Treasuries and other government money market funds.
State Street's parallel push
State Street unveiled the State Street Stablecoin Reserves Money Market Fund, a similar product to Fidelity's offering. The timing—Fidelity's launch coming just days after State Street's—underscores how Wall Street's largest custodians are positioning themselves in tokenized finance. State Street framed its stablecoin reserves product launch as part of a broader push into tokenized finance through partnerships with crypto firms such as Anchorage Digital.
For issuers, these institutional-grade products offer regulatory clarity and operational simplicity. Instead of managing reserve assets separately, they can deposit them into a single fund that meets federal requirements. Fidelity's move signals the firm sees stablecoin reserves as a durable business line, not a temporary experiment.
