State Street rolls out GENIUS-aligned money market fund for stablecoin reserves
Anchorage Digital and State Street Bank are initial investors in the Rule 2a-7 government fund.
State Street Investment Management launched a Rule 2a-7 government money market fund built for stablecoin issuers seeking GENIUS Act-aligned reserve holdings. The product lands as banks and asset managers race to intermediate a growing pool of Treasury and repo collateral backing payment stablecoins.
Key Takeaways
- State Street Investment Management launched a Rule 2a-7 government money market fund designed for stablecoin reserve portfolios.
- The strategy targets the same reserve building blocks used across major stablecoins: US government securities and repurchase agreements.
- State Street Bank and Anchorage Digital are listed as initial investors, pairing a traditional custody balance sheet with federally chartered crypto banking rails.
- The fund is positioned to meet reserve requirements under the GENIUS Act, described as having been signed into law on July 18, 2025.
State Street Launches a GENIUS-Aligned Reserve Fund for Stablecoin Issuers
State Street Investment Management has launched a money market fund aimed at stablecoin issuers that want a compliant place to park reserve assets under the GENIUS Act framework. The vehicle is structured as a Rule 2a-7 government money market fund, a format built around strict liquidity and risk limits that fits the direction of travel for regulated payment-stablecoin reserves.
Initial investors include State Street Bank and Anchorage Digital, which is described as a federally chartered crypto bank. That pairing matters for distribution. It suggests the product is being positioned not just as an asset-management wrapper, but as an institutional reserve rail that can sit alongside crypto-native banking infrastructure.
State Street framed the launch as designed to comply with reserve requirements established under the GENIUS Act, described as having been signed into law on July 18, 2025 and creating the first federal regulatory framework for payment stablecoins in the US.
Inside the Portfolio: Treasurys and Repo as the Reserve Backbone
The fund will invest in US government securities and repurchase agreements. That is not a new reserve concept. It is the institutional packaging of what already dominates stablecoin backing: short-duration government exposure and cash-like financing.
The reserve mix also mirrors what the largest issuers already hold. Tether’s March 2026 reserves report showed approximately $191.8 billion in assets backing USDT, with US Treasury bills accounting for the majority of its cash-equivalent reserves.
The implication for traders is structural rather than flashy. GENIUS-era compliance appears to be converging on the same instruments that already clear at scale in money markets, which lowers friction for large allocators and increases the incentive for incumbents to compete on operational execution, liquidity terms, and distribution.
Wall Street’s Race for Stablecoin Reserves: JPMorgan, Morgan Stanley, and Coinbase/ProShares
State Street’s launch lands in a fast-forming category of GENIUS-aligned reserve vehicles. In May, JPMorgan filed to launch JLTXX, described as a tokenized money market fund intended to hold assets backing stablecoins while complying with GENIUS Act requirements, with investments in US Treasury bills and overnight repurchase agreements.
Weeks before that filing, Morgan Stanley launched a Stablecoin Reserves Portfolio, described as a money market fund that allows stablecoin issuers to hold reserve assets while earning interest. In June, Coinbase disclosed an investment in the ProShares GENIUS Money Market ETF, described as a Treasury-focused fund investing in assets eligible to back payment stablecoins under the law.
The competitive logic is straightforward. The stablecoin market grew to approximately $315 billion from about $260 billion when the GENIUS Act was signed, according to DefiLlama data. State Street also cited Citi projections estimating global stablecoin issuance could reach between $1.9 trillion and $4 trillion by 2030. If reserves scale with issuance, the fee pool and balance-sheet utility scale with them.
Adoption Signals Traders Can Track as Reserve Products Multiply
Near-term, the market will need basic disclosure to price the seriousness of the push: the fund’s name or ticker, assets under management at launch, fee schedule, and any yield targets were not provided.
Another key detail is product plumbing. State Street previously introduced the State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP), described as a tokenized liquidity product developed with Galaxy Digital enabling onchain cash management using stablecoins. The new reserve fund’s tokenization or onchain settlement status was not specified, and that distinction will shape who can use it and how quickly.
The cleanest adoption signal is issuer allocation. Beyond State Street Bank and Anchorage Digital as initial investors, there was no confirmation of specific stablecoin issuers moving reserves into the fund. Traders can also track whether more major banks and asset managers follow with additional GENIUS-aligned filings and launches after JPMorgan’s JLTXX and Morgan Stanley’s reserves portfolio.
Marcus Hale’s Take: GENIUS Compliance Is Becoming the Distribution Edge
I treat this as a market-structure story: reserve compliance is turning into a product shelf, and the shelf is filling fast. State Street, JPMorgan, Morgan Stanley, and ProShares are all pointing at the same core collateral set, Treasurys and repo, which tells you the fight is less about inventing new reserve assets and more about who gets the mandate and the operating relationship.
The threshold that matters is whether named stablecoin issuers start allocating meaningful reserves into these GENIUS-aligned vehicles, and whether those allocations come with tokenized settlement that tightens the loop between onchain cash management and offchain money markets. If that bridge holds, the setup starts to look structural rather than narrative-driven, because reserve flows become a repeatable distribution channel into T-bills and repo at scale.
