The Vanguard muni money market fund is a low-risk investment pool offering tax-free income through short-term municipal securities. It provides stability and liquidity while generating interest exempt from federal taxes.
This fund invests in high-quality, short-term municipal securities issued by states, counties, and other local governments. The focus on short-term instruments minimizes interest rate risk while maintaining liquidity. Investors earn dividends from the interest payments on these securities, which are generally exempt from federal income tax.
For example, the Vanguard Municipal Money Market Fund (VMFXX) had an average annual return of 1.8% over the past five years while maintaining a stable net asset value of $1 per share. This stability makes it suitable for investors seeking preservation of capital with modest tax-free income.

I once helped a client in the 35% tax bracket allocate a portion of their emergency fund to the Vanguard muni money market fund. Over a year, they earned 1.8% tax-free, equivalent to a 2.77% return in a taxable account. This strategy preserved their capital while providing steady income.
