State Street Launches GENIUS-Compliant Money Market Fund for Stablecoin Reserves

State Street Investment Management has introduced a new money market fund aimed at stablecoin issuers, giving them a regulatory-aligned way to park reserve assets in US government securities and related instruments. The firm said the product is designed to fit within the reserve requirements created by the GENIUS Act—U.S. legislation signed on July 18, 2025 that established the first federal framework for payment stablecoins.

The fund is structured as a Rule 2a-7 government money market fund and is intended for investors including State Street Bank and Anchorage Digital, according to State Street. The move highlights how quickly traditional asset managers are trying to capture the emerging pool of “reserve-adjacent” capital that stablecoin compliance requires.

Key takeaways

• State Street Investment Management launched a Rule 2a-7 government money market fund for stablecoin issuers’ reserves under the GENIUS Act framework.
• The fund will invest in assets commonly used for stablecoin backing, including US government securities and repurchase agreements.
• Anchorage Digital—described by State Street as a federally chartered crypto bank—was named among the initial investors.
• The launch arrives amid an expanding race among major financial institutions to offer compliant stablecoin reserve and cash-management products.
• Stablecoin issuance has grown since the GENIUS Act was signed, with DefiLlama data cited by State Street.

A compliant “reserve vehicle” enters the market

For stablecoin issuers, reserve management is no longer just an operational choice—it is increasingly tied to regulatory structure. State Street’s newly launched fund is built to provide a pool of high-quality, short-term assets that can be used as reserves, using a regulatory wrapper investors are already familiar with.

State Street said the fund’s design is meant to comply with reserve requirements established by the GENIUS Act. By positioning the product as a Rule 2a-7 government money market fund, the firm is effectively mapping traditional money market infrastructure to the stablecoin compliance problem: holding liquid, yield-bearing instruments that regulators can view as suitable backing.

While the underlying asset categories—US government securities and repurchase agreements—are familiar to fixed-income investors, the significance lies in how the assets are bundled and offered specifically for stablecoin reserve use cases. In practice, that can reduce friction for issuers that must demonstrate compliance and maintain consistent liquidity profiles.

State Street’s stablecoin-related product expansion

This launch also follows State Street’s introduction of a tokenized liquidity product. The company previously unveiled the “State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP),” developed with Galaxy Digital, which is designed to enable onchain cash management using stablecoins.

That sequence matters: it suggests a strategy that pairs onchain liquidity tooling with off-chain reserve management products under a federal regulatory framework. As the stablecoin industry develops clearer compliance rails, traditional finance players appear to be working to cover both ends of the workflow—capital movement on-chain and reserve handling in regulated vehicles.

GENIUS Act competition heats up among major firms

State Street’s entry is part of a broader wave of filings and product launches targeting stablecoin reserve assets since the GENIUS Act took effect. According to details cited in the source, several major institutions have already moved to build compliant offerings.

In May, JPMorgan filed plans for JLTXX, described as a tokenized money market fund intended to hold assets backing stablecoins while complying with the GENIUS Act’s requirements. The filing indicated that the fund would invest in US Treasury bills and overnight repurchase agreements—again aligning with the instruments widely used in stablecoin reserve strategies.

Earlier, Morgan Stanley introduced a “Stablecoin Reserves Portfolio,” a money market-style approach allowing stablecoin issuers to hold reserve assets and earn interest. Coinbase also disclosed an investment in the ProShares GENIUS Money Market ETF, a Treasury-focused fund that invests in assets eligible to back payment stablecoins under the law, framing the move as aligned with its growing stablecoin and cash-management activities.

Taken together, these efforts show a competitive pattern: rather than each issuer reinventing reserve operations, the market is increasingly offering standardized pools and wrappers—some tokenized, some traditional—that claim compatibility with the GENIUS Act’s reserve expectations.

Why reserve management has become a business battleground

The push into stablecoin reserve products is supported by the growth of the stablecoin sector itself. State Street cited DefiLlama data indicating the stablecoin market has expanded to around $315 billion, up from roughly $260 billion at the time the GENIUS Act was signed. The cited projections from Citi referenced by State Street suggest global stablecoin issuance could reach between $1.9 trillion and $4 trillion by 2030.

Those figures matter because reserve assets scale with issuance. As more stablecoin dollars come into circulation, the amount of assets that must be held—often in cash-like instruments—can increase, creating demand for vehicles capable of meeting both liquidity and regulatory requirements.

The reserve management challenge is visible in transparency reporting from major issuers as well. For example, Tether’s March 2026 reserves report, linked in the source, states that it held approximately $191.8 billion in assets backing USDT, with US Treasury bills forming the majority of its cash-equivalent reserves. While different issuers use different reserve mixes, the overall pattern—heavy reliance on Treasury bills and similar short-dated instruments—lines up closely with the asset categories referenced in State Street’s new fund.

What to watch next

State Street’s fund launch underscores that GENIUS Act compliance is quickly becoming a product opportunity rather than only an operational hurdle. Investors and builders should watch how quickly reserve-focused funds scale their adoption with issuers, and whether more tokenized or traditional money market offerings appear that explicitly target stablecoin reserve allocations under the new federal framework.
