Fidelity Government Cash Reserves (FDRXX) is a money market mutual fund that seeks a high level of current income consistent with the preservation of capital and liquidity by investing primarily in U.S. government securities and repurchase agreements collateralized by such securities, including Treasury bills, notes, and bonds; government agency securities; and cash. The fund maintains a portfolio focused on high-quality, short-term instruments with weighted average maturities typically under 60 days and adheres to industry-standard regulatory requirements for quality, maturity, liquidity, and diversification in the money market sector. It serves institutional and retail investors seeking stable, liquid cash management solutions, with operations centered in the United States and total net assets exceeding $238 billion as of late 2025.
Established in 1979 and managed by Fidelity Investments, headquartered at 245 Summer Street, Boston, Massachusetts, the fund operates within Fidelity's broader family of money market funds offered through its institutional and retail platforms. Core offerings emphasize daily liquidity, competitive yields such as 7-day and 30-day yields calculated in compliance with SEC standards, and minimal expense ratios around 0.37% to 0.39%, with no front-end or deferred loads. The fund targets cash reserves for brokerage accounts, retirement plans, and institutional portfolios, prioritizing U.S. government-backed holdings to minimize credit risk.
In recent developments, the fund has maintained stable operations amid fluctuating interest rates, with no reported major acquisitions, partnerships, or structural changes in 2024 or 2025; however, Fidelity Investments as a whole reported strong third-quarter 2025 results with segment growth supporting ongoing money market fund management. Portfolio composition continues to emphasize U.S. direct obligations and full faith & credit securities, rated AAAm by S&P and Aaa-mf by Moody's, reflecting consistent risk management without significant strategic shifts or new product launches specific to FDRXX. Net assets have grown steadily, underscoring its role in Fidelity's cash management ecosystem alongside offerings like the Fidelity Cash Management Account.
