- State Street Institutional Investment Trust - Treasury Fund is a U.S. Treasury-only institutional money market fund managed by State Street Global Advisors, founded in 2007 and based in Boston, Massachusetts, that seeks to provide a high level of current income consistent with preserving principal, maintaining liquidity, and sustaining a stable $1.00 per share net asset value. The fund offers the Premier Class share class under ticker TRIXX and is structured for institutional investors, including cash sweep and other cash-management clients, with investment operations focused on U.S. Treasury bills, notes, and bonds as direct obligations of the U.S. government. The fund’s core service is short-term cash preservation and government-backed income management, supported by money market portfolio administration, daily liquidity, and regulatory compliance applicable to money market funds; recent fund data show substantial net assets and continued Treasury-only positioning. In the last 1-2 years, State Street has continued to update its cash platform and related fund lineup, including 2025-2026 trust document updates, share-class and series filings, and broader product and operational changes across its investment management business, while the Treasury Money Market Fund itself continued to operate with current prospectus and fact-sheet updates as of 2026.
