iShares Government Money Market ETF (GMMF) seeks to provide current income consistent with preservation of capital and liquidity by investing in high-quality, short-term U.S. government securities and repurchase agreements. This money market ETF focuses on Treasury bills, government agency debt, and collateralized repurchase agreements with maturities typically under 397 days.
How It Works
GMMF employs an actively managed approach, selecting government securities based on credit quality, yield, and maturity profiles to maintain stable net asset value around $1.00 per share. The fund's portfolio manager adjusts holdings daily based on interest rate movements and cash flow needs, maintaining a dollar-weighted average maturity of 60 days or less. Holdings consist entirely of U.S. government-backed securities, providing the highest credit quality available in money markets.
Key Features

- ETF structure provides intraday liquidity unlike traditional money market mutual funds with end-of-day pricing
- 2.84% dividend yield reflects current short-term government rates, paid monthly to shareholders
Risks
- This ETF can lose value if interest rates rise rapidly, causing existing securities to decline in value before maturity
- Government policy changes or debt ceiling crises could temporarily disrupt Treasury markets and impact fund liquidity
- Inflation risk means purchasing power erodes if the 2.84% yield fails to keep pace with rising prices
