The Vanguard Intermediate-Term Tax-Exempt Fund Overview
Summary: The Vanguard Intermediate-Term Tax-Exempt Fund (VWITX) would be a solid choice for a passive national municipal bond fund.
Commentary: With $36 Billion under management the Vanguard Intermediate Term Tax Exempt Fund is the largest municipal bond fund in the world. Because of its size this is technically an actively managed fund. It is too big to be 100% passively managed in the less liquid municipal bond market. However, the managers hold themselves to very tight restrictions in relation to the underlying municipal bond index it tracks, so it resembles a passively managed fund more than an active fund. The fund also gives you similar performance but with less volatility than another popular passive national municipal bond fund the MUB ETF. This is why we list it as a passive fund.

This is a great fund, but that does not mean that you will not lose money investing in the fund. Currently the fund has a duration of around 5 years. This means that if interest rates rise by 1%, the fund will lose 5% in value. If interest rates don’t change you should earn around 1.66% per year from interest payments, per year, based on the fund’s current SEC yield. Keep in mind that 1.66% is before taxes. The taxable equivalent yield for someone in the 35% tax bracket would be 2.55%. To see what it would be for you, use our municipal bond calculator here.
