What is Money Market Fund?
A money market fund is a mutual fund that invests in highly liquid, short-term debt instruments such as cash equivalents and government securities. Designed to preserve capital and maintain liquidity, these funds offer a stable investment option with low risk.
They differ from savings accounts by investing primarily in high-quality securities, often maintaining a net asset value close to $1.00 per share through amortized cost accounting.
Key Characteristics
Money market funds share several defining features that make them attractive for conservative investors:
- Low credit risk: They invest mainly in AAA-rated securities, ensuring high credit quality and safety (AAA rating).
- High liquidity: Investors can typically withdraw funds quickly without penalties.
- Stable Net Asset Value (NAV): Uses amortized cost accounting to keep NAV near $1.00 per share.
- Diversified portfolio: Holdings include U.S. Treasury bills, commercial paper, and certificates of deposit.
- Regulated investments: Subject to SEC rules on quality, maturity, and diversification.
How It Works
You invest cash in a money market fund, which then pools your money with other investors to purchase a diversified portfolio of short-term debt securities. The fund manager selects instruments such as commercial paper and Treasury bills to generate income while preserving capital.
Returns are typically paid as dividends or reinvested, with the fund maintaining a stable value via amortized cost accounting, unlike other funds that fluctuate with market prices. Many investors use these funds as a short-term cash management tool or a bond ETF alternative for liquidity.
Examples and Use Cases
Money market funds serve various practical purposes for individual and institutional investors:
- Cash management: Investors seeking a safe place to hold cash temporarily before deploying it elsewhere often use money market funds.
- Emergency funds: Their liquidity and stability make them ideal for emergency savings.
- Corporate treasuries: Companies like Delta may use money market funds as part of their short-term liquidity strategy.
- Alternative to paper money: Instead of holding physical currency, some investors prefer money market funds for convenience and yield (paper money).
Important Considerations
While money market funds are low risk, they are not risk-free; investors should be aware of potential fluctuations in yield and the rare possibility of NAV deviations. Additionally, returns are generally lower than longer-term investments.

Final Words
Money market funds offer a low-risk option for preserving capital while earning modest returns through short-term debt investments. To optimize your portfolio, compare fund fees and yields before committing your cash.
