Fidelity Launches Stablecoin Reserve Fund as Wall Street Race Heats Up

Fidelity Investments is launching a money market fund for stablecoin reserves on Thursday, joining State Street and other Wall Street firms in a push to manage the cash and Treasury bills that back digital dollars. The Fidelity Reserves Digital Fund, debuting June 18, is built around the reserve rules in the GENIUS Act, the federal law that created the first U.S. framework for payment stablecoins.

The Fund and What Goes Into It

Fidelity’s new fund opens on Thursday as a money market vehicle aimed at stablecoin issuers and institutional investors that need to comply with the law’s reserve rules. CoinDesk reported the launch on June 17, noting that Fidelity designed the product to manage the Treasury bills, cash and other short-term instruments issuers must hold against outstanding stablecoin tokens. The fund is the latest in a string of Wall Street moves into the stablecoin reserve business that picked up speed after the federal stablecoin framework became law. Fidelity, one of the largest U.S. asset managers, brings a fixed-income platform to the table that few competitors can match at the same scale.

The fund will invest in U.S. Treasury bills, notes and bonds with maturities of 93 days or less, plus cash, overnight repurchase agreements backed by Treasuries, and other government money market funds that comply with the law. The structure mirrors the kind of conservative, ultra-short-duration portfolio that traditional corporate cash managers have used for decades, repackaged for a new class of buyers. The 93-day maturity cap tracks the law’s preference for short-dated, low-risk assets.

Fidelity has a longstanding history in fixed income and money markets, making us uniquely positioned to offer a money market fund for stablecoin issuers that is compliant with the new GENIUS-Act legislation.

That statement came from Robin Foley, Fidelity’s head of fixed income, on the day the firm announced the fund. Foley runs the same fixed-income platform that handles Fidelity’s other short-duration products. The fund gives stablecoin issuers a vehicle to park reserves in line with the law without building the treasury and repo operations in-house. Both functions are already in place at Fidelity, and the fund packages them for the new class of buyers.

A Two-Day Head Start for State Street

Fidelity’s fund is not the first of its kind. State Street Investment Management rolled out the State Street Stablecoin Reserves Money Market Fund two days ahead of Fidelity’s debut, CoinDesk reported. State Street framed its product as the first piece of a larger tokenized-finance push and seeded it with capital from State Street Bank and Trust Company and Anchorage Digital, the crypto-focused bank that holds a federal charter in the United States.

The two funds share a structure. Both are government money market funds that invest in the short-dated Treasuries and repurchase agreements the law counts as permissible reserves. The differentiator is positioning. State Street is bundling its offering with SWEEP, a tokenized liquidity fund it developed with Galaxy Digital, and pitching the combined package to issuers that want native onchain integration. The pitch to issuers is that State Street can deliver the reserve account and the onchain cash management layer in a single relationship.

For Fidelity, the head start is a problem it cannot buy back with marketing. State Street already has a live fund and a federally chartered crypto partner on its cap table, and Fidelity is now selling into the same narrow buyer base. Both firms are pitching the handful of stablecoin issuers and institutional treasury teams that will pick the first GENIUS Act-compliant reserve accounts.

BlackRock’s Circle Connection and the Wider Field

The race does not start from a clean line. BlackRock already oversees much of the Treasury portfolio backing Circle’s $75 billion USDC stablecoin, a multi-year head start in the most lucrative corner of the market. The arrangement gives BlackRock a built-in client relationship for the new fund era.

Franklin Templeton and JPMorgan have each expanded tokenized cash and digital asset offerings over the past year. The competitive set now reads like a who’s who of the largest U.S. asset managers, with five players already in or entering the space. The BlackRock-managed Circle Reserve Fund is the incumbent on the list.

• BlackRock: Circle Reserve Fund
• State Street: State Street Stablecoin Reserves Money Market Fund
• Franklin Templeton: tokenized cash offerings
• JPMorgan: tokenized cash offerings

The $320 Billion Market That Could Hit $4 Trillion

The size of the prize is what brought all four of the other managers to the table alongside Fidelity. Stablecoins are widely used for trading, payments and cross-border transfers, and the market is large enough that reserve management has become a new fee pool for asset managers. Industry participants project significant growth as institutional adoption expands, creating a corresponding pool of reserve assets that must be invested in highly liquid instruments.

The asset manager that lands the largest mandates gets the fee revenue, and the early launches by BlackRock, State Street, and now Fidelity are all positioning for that race. Tether and Circle, the two largest stablecoin issuers, collectively hold tens of billions of dollars in Treasury-related assets today. Every basis point of yield on those balances is a fee opportunity for whichever manager wins the mandate. The fee economics are why a fund that looks like a routine money market product is being treated as a strategic priority across the industry.

Those projections come with caveats. The high end of the range assumes institutional adoption keeps accelerating, that the U.S. regulatory framework stays friendly, and that no major stablecoin issuer defaults or faces a run. None of those is guaranteed. The fund launches will show whether the projected scale is real, with each new product giving the market a fresh data point. The fact that four other major asset managers have launched or backed stablecoin reserve products, and that the most recent two launched within a week of each other, is the part of the story that is already on the page.

• $320 billion: Current size of the global stablecoin market
• $1.9 trillion to $4 trillion: Projected market size by 2030
• June 16, 2026: State Street’s fund launch
• June 18, 2026: Fidelity’s fund launch
• $5 trillion: Fidelity’s assets under management

What the GENIUS Act Forces on Issuers

The GENIUS Act, signed into law last year, established the first federal framework for payment stablecoins in the United States. Among other requirements, it forces issuers to hold reserves in cash, short-term Treasury securities, and certain government money market funds, the same asset classes the new Fidelity and State Street funds are built around. The law’s reserve rules effectively redrew the map for stablecoin reserve management. Issuers can no longer hold reserves in commercial paper, longer-dated corporate debt, or the kind of in-house yield strategies that some used before the law. The permissible reserve assets are now a defined list, and funds like Fidelity’s and State Street’s are the first attempts to productize the answer.

The list of permissible reserves is short and specific. Issuers can hold cash, U.S. Treasury securities with short maturities, repurchase agreements backed by Treasuries, and government money market funds that meet the law’s standards. The Office of the Comptroller of the Currency and other federal regulators are still writing the implementing rules. The OCC’s proposed rules implementing the GENIUS Act are the most concrete signal so far of how the framework will operate in practice.

The OCC’s bulletin on the GENIUS Act rulemaking was published earlier this year, and federal regulators are working through the rest of the implementing rules. Until those rules land, issuers and managers are moving on best-faith interpretations of what the law allows. The funds Fidelity and State Street just launched are the most concrete attempt so far to package the answer into a product issuers can buy. The next round of rulemaking will determine whether those products need to be restructured or can stay as is.

What Issuers Get From the New Competition

Tether and Circle, the two largest stablecoin issuers, collectively hold tens of billions of dollars in Treasury-related assets, and the next round of fund mandates will go to whichever Wall Street manager lands the first big check. Both Fidelity and State Street have built products designed for exactly that mandate, and BlackRock’s Circle Reserve Fund has been the de facto benchmark for years. Issuers tend to concentrate reserves with one or two managers to simplify reporting.

The competitive pressure cuts both ways for issuers. They gain access to funds tailored for the specific compliance demands of the GENIUS Act, with yield, liquidity and reporting built into the structure. Two or three large managers competing for the same balance gives an issuer room to negotiate on fees. State Street’s pitch leans on its Anchorage Digital partnership and the SWEEP tokenized fund developed with Galaxy Digital. Fidelity’s pitch leans on its fixed-income platform and the long track record Foley cited in the announcement.
