What Is a United States Treasury Money Mutual Fund?
A United States Treasury money mutual fund is a mutual fund that pools money from investors to purchase low-risk government securities. A United States Treasury money mutual fund is a type of mutual fund that invests primarily or exclusively in U.S. government debt, such as Treasury bills and repurchase agreements. U.S. Treasury money mutual funds are a leading investment for investors seeking to preserve principal or invest cash temporarily.
- A U.S. Treasury money mutual fund invests in low risk and highly liquid investments such as U.S. Treasury bills.
- These funds are ideal for investors seeking stable investments that preserve invested principal.
- Money mutual funds are regulated by the Securities and Exchange Commission (SEC), which stipulates rules regarding maturity, credit quality, and liquidity of securities.
Understanding a United States Treasury Money Mutual Fund
U.S. Treasury money mutual funds are one of the industry’s best low-risk investments. These mutual funds typically invest in U.S. Treasury bills and are highly stable and liquid. These funds are generally classified as either money market funds or found in low-risk fixed income categories. Treasury bills are secured by the full faith and credit of the United States Treasury, which helps to make these portfolios reliable sources of low-risk returns due to the country’s developed economy and political stability.
U.S. Government Money Market Funds
Money managers across the industry offer money market mutual funds that fully invest in U.S. Treasuries. U.S. government money market mutual funds follow standard accounting principles that help to keep their net asset value at $1 per share at amortized cost rather than market value. These funds register as money market funds and are governed primarily by Rule 2a-7 of the Investment Company Act of 1940.
The rule stipulates the type of quality the funds can invest in, ensuring that only the highest-rated debt is included. Rules cover the maturity, credit quality, and liquidity of the securities invested. Under the rule, in regards to maturity, the average dollar-weighted maturity cannot exceed 60 days. No more than 3% of assets can be invested in debt that is not in the first or second ranked tier in regards to credit quality, and under liquidity rules, 10% of assets must be able to be converted into cash within one day, 30% within five days, and no more than 5% can be held in securities that take longer than a week to convert into cash.
Rules and regulations for money market funds have been revised to provide even greater security for investors since the 2008 financial crisis when the popular Reserve Primary Fund broke the buck by falling below its $1 net asset value.
Often, U.S. government money market funds managed by brokerage service providers will be offered as cash sweep options or no transaction fee funds. Some of the most popular U.S. government money market funds include:
Vanguard Treasury Money Market Fund
Fidelity Treasury Only Money Market Fund
American Century Capital Preservation Fund
