Definition
A money market fund is a type of mutual fund that primarily invests in high-quality, short-term debt instruments, cash equivalents, and other low-risk securities. These funds aim to provide investors with high liquidity and a safe place to park their cash while earning a modest return.
Key Characteristics
- Investment in High-Quality Debt: Money market funds invest in high-grade commercial paper, Treasury bills, repurchase agreements, and certificates of deposit (CDs).
- Short-Term Maturity: These funds typically invest in instruments with maturities of less than one year.
- Liquidity: Investors can typically access their funds quickly, making money market funds highly liquid.
- Low Risk: The risk of default is minimal because of the high credit quality of the investments.
Functionality of Money Market Funds
How They Work
Money market funds pool money from multiple investors to purchase a diversified portfolio of short-term financial instruments. The fund’s value is kept relatively stable, usually maintaining a net asset value (NAV) of $1 per share.
Yield and Returns
The yield on a money market fund is influenced by the prevailing interest rates. Although the returns are lower compared to other investment types, the safety and stability they offer make them an attractive choice for risk-averse investors.

Prime Money Market Funds
Invest in a variety of corporate and government securities. These funds offer a potentially higher return but come with slightly higher risk.
Government Money Market Funds
Focus exclusively on U.S. government securities, such as Treasury bills and repurchase agreements backed by the government, offering the highest level of safety.
Tax-Exempt Money Market Funds
Invest in short-term municipal securities, providing tax-free income for investors in higher tax brackets.
