What BND actually is
BND is Vanguard’s ETF for the broad US investment-grade bond market. Instead of stocks, it holds thousands of bonds: US Treasuries and other government debt, corporate bonds from creditworthy companies, mortgage-backed securities and international dollar-denominated bonds. All have maturities of more than one year.
It launched in 2007 and is one of the largest bond funds in the world. Because it holds so many bonds, Vanguard tracks the index using sampling rather than owning every single one.
How it makes money for you
A bond pays interest, and BND collects that interest and distributes it to shareholders every month. Strictly speaking, these payments are not company dividends, but they appear in your account in the same way. The yield has typically been higher than that of US stock funds, and the monthly rhythm makes it popular with investors who want predictable cash.
Costs
Costs matter more in bonds than in stocks, because returns are lower, so each fraction of a percent in fees takes a bigger bite. Check the fund’s current expense ratio on Vanguard’s website.
What drives the price
Bond prices move in the opposite direction to interest rates. When rates rise, the price of existing bonds falls, and BND falls with them. The longer the bonds’ maturities, the stronger the effect. That is why bond funds lost value in 2022 when rates climbed quickly. When rates fall, the reverse happens.
What to keep in mind
- Interest-rate risk. Rising rates reduce the share price.
- Inflation. It can erode the real value of fixed payments.
- Credit risk is lower than in high-yield bonds but not zero.
- Lower long-term growth than stocks.
Quick take
BND is a stabiliser for a portfolio: lower expected return than stocks, regular monthly income and typically smaller swings. It pairs naturally with stock funds such as VTI or VOO.
