Not all bond ETFs behave the same. Here's how bond duration changes risk, returns and how your portfolio reacts to interest rates.
In partnership with:

If you've ever looked into investing beyond shares, bonds have probably come up.
They're one of the most common assets held inside fixed income ETFs… and for good reason. Bonds are issued by governments and companies to raise money, and in return, they pay you regular interest.
But here’s the thing: not all bond ETFs are created equal.
Some bonds barely move when interest rates shift. Others can swing enough to make you double-check you didn’t accidentally buy shares.
The difference? Time.
At a high level, it’s pretty simple:
But this isn’t just about how long you hold onto your investment. It’s about how your investment behaves.
You see, bond prices and interest rates are in a bit of a situationship.
When interest rates go up, bond prices tend to go down. And when interest rates go down, bond prices tend to go up.
Just like the classic push and pull attraction people love to romanticise in romcoms.
We break down this relationship in more detail here.
Now multiply this see-saw effect with the duration of a bond.
Generally speaking, the longer the bond term, the bigger the reaction.
This means:
Why does this happen?
Long-term bonds react more because you’re locked in for longer. That means when the interest rate shifts, your bond can suddenly look like a steal… or a very bad deal.
Depending on your goals, you might want to pick either short-term bond ETFs or long-term bond ETFs.
Short-term bond ETFs might suit you if you:
Whereas long-term bond ETFs might be better if you:
After a stretch of rising interest rates, long-term bond ETFs have had a bumpier ride. But that also means they’re more sensitive to what happens next.
While the common “bonds are safe” gets thrown around a lot, it’s still important to understand the difference in bond duration and how they impact your portfolio.
Because bonds can help reduce overall portfolio risk, but that doesn’t mean they don’t move.
