Money Market Funds

Low-Risk Investment Vehicles for Cash Management

Money market funds are mutual funds that invest in short-term debt securities with high liquidity and minimal credit risk. They offer investors a balance of safety, accessibility, and modest returns for their cash reserves.

Understanding Money Market Funds

Fundamentals of Money Market Funds

What Are Money Market Funds?

Money market funds are a type of mutual fund that invests exclusively in highly liquid, short-term instruments:

Regulated investment vehicles that seek to maintain a stable Net Asset Value (NAV), typically $1 per share
Invest in high-quality, short-term debt instruments with maturities under 13 months
Designed to provide liquidity, preserve capital, and deliver competitive short-term yields
Safety and Risk Profile

While considered among the safest investment options, money market funds are not entirely risk-free:

Not FDIC insured like bank deposits, though risk of principal loss is very low
SEC Rule 2a-7 sets strict standards for credit quality, maturity, and diversification
Historical note: During the 2008 financial crisis, one fund "broke the buck" (fell below $1 NAV), leading to regulatory reforms
Liquidity and Accessibility

Money market funds offer high liquidity, making them suitable for short-term cash needs:

Same-day or next-day access to funds in most cases
Often provide check-writing privileges and debit card access
No penalties for withdrawals (unlike some CDs or time deposits)

Types of Money Market Funds

Major Money Market Fund Categories

Government Money Market Funds

Invest primarily in U.S. Treasury securities, government agency debt, and repurchase agreements collateralized by government securities.

Risk level: Lowest among money market funds due to government backing

Use case: Most conservative investors seeking maximum safety
Prime Money Market Funds

Invest in high-quality, short-term corporate debt instruments in addition to government securities.

Risk level: Slightly higher than government funds but still very low
Yield: Generally higher than government money market funds
Note: Subject to potential redemption gates and liquidity fees during extreme market stress
Tax-Exempt Money Market Funds

Invest in short-term municipal securities issued by state and local governments.

Risk level: Comparable to prime money market funds
Yield: Lower pre-tax yields but may offer higher after-tax returns for those in higher tax brackets
Tax advantage: Interest is generally exempt from federal income tax (and sometimes state and local taxes)
Treasury-Only Money Market Funds

A subset of government funds that invest exclusively in U.S. Treasury bills, notes, and bonds.

Risk level: Considered the safest of all money market funds
Yield: Typically lowest yields among money market funds

Parking funds during periods of market uncertainty or while evaluating investment options

As part of a broader investment strategy:

Cash allocation in a diversified portfolio to reduce overall volatility
Temporary holding place for rebalancing proceeds or dividend distributions
Defensive position during periods of expected market turbulence
Specific Financial Goals

Saving for a major purchase planned within the next 1-2 years
Setting aside money for upcoming tax payments
Accumulating funds for an upcoming large expense like tuition payments

How to Choose a Money Market Fund

1. Consider the expense ratio. Fees can significantly impact your returns, especially in low-interest environments. Look for funds with expense ratios below 0.25%.

2. Examine the yield. Compare the 7-day SEC yield among similar funds, but remember that past yields don't guarantee future returns.

3. Assess your tax situation. If you're in a high tax bracket, tax-exempt money market funds might provide better after-tax returns despite lower headline yields.

4. Review fund composition. Check what types of securities the fund invests in and ensure they align with your risk tolerance.

5. Consider convenience features. Minimum investment requirements, check-writing privileges, and integration with your existing accounts can impact usability.
