State Street Drops $5T Muscle Behind GENIUS Act Stablecoin Reserve Play 💰

State Street Investment Management has launched a money market fund built specifically for stablecoin issuers, marking one of the largest traditional asset managers to formally enter the reserve infrastructure market created by the GENIUS Act. The State Street Digital Reserve Fund, trading under the ticker SSCXX, was structured as a Rule 2a-7 government money market fund and invests in assets commonly used to back stablecoins, including US government securities and repurchase agreements. The fund officially launched on June 8 and carries a minimum investment threshold of $15 million, positioning it for institutional stablecoin issuers, payment firms, and treasury managers rather than retail investors. Initial investors include State Street Bank and Anchorage Digital, a federally chartered crypto bank serving as launch partner.

The product was designed to comply with reserve requirements established under the GENIUS Act, which was signed into law on July 18, 2025, creating the first federal regulatory framework for payment stablecoins in the United States. State Street said the fund seeks to provide "a high level of current income consistent with preserving principal and liquidity," aligning it closely with the reserve-management requirements increasingly associated with regulated stablecoins. State Street Investment Management, the asset management arm of State Street Corporation, oversees more than $5 trillion in assets and is one of the world's largest investment managers. The launch follows the introduction of the State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP), a tokenized liquidity product developed with Galaxy Digital that enables onchain cash management using stablecoins.

State Street's move comes as financial firms race to build products aimed at managing the assets backing stablecoins. In May, JPMorgan filed to launch JLTXX, a tokenized money market fund intended to hold assets backing stablecoins while complying with requirements established under the GENIUS Act. The fund would invest in US Treasury bills and overnight repurchase agreements, assets commonly used to back dollar-pegged stablecoins. Weeks earlier, Morgan Stanley launched its Stablecoin Reserves Portfolio, 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, a Treasury-focused fund that invests in assets eligible to back payment stablecoins under the law.

The stablecoin market has grown to approximately $315 billion from about $260 billion when the GENIUS Act was signed into law, according to DefiLlama data. State Street cited projections from Citi estimating global stablecoin issuance could reach between $1.9 trillion and $4 trillion by 2030. According to Tether's March 2026 reserves report, the company held approximately $191.8 billion in assets backing USDT (USDT), with US Treasury bills accounting for the majority of its cash-equivalent reserves. The accumulation of traditional finance firms around stablecoin reserve infrastructure reflects a broader shift in how dollar-backed digital assets are treated across the financial system.
