According to State Street, the firm launched the SSCXX Stablecoin Reserves Money Market Fund on June 8, 2026, with approximately $121 million in assets under management and a 3.51% yield. The fund carries a 0.18% net expense ratio on the Capital Class share and requires a $15 million minimum investment.
State Street enters the stablecoin reserve market behind BlackRock, which partnered with Circle on a Treasury Reserves fund, and Goldman Sachs and BNY Mellon, which launched GENIUS Act-aligned reserve vehicles earlier in 2026. Anchorage Digital joined as a seed investor, combining its federally chartered crypto bank infrastructure with State Street's cash management platform.
