Simple definition
Reinvestment risk is the chance that when a bond or CD matures — or pays you interest along the way — you can only put that money back to work at a lower interest rate than before. Think of it like a great-paying job ending, and the next one paying less. It bites most when rates have fallen.
Why it matters
Reinvestment risk is easy to overlook because your bond didn't lose money — you got paid back in full. The catch is what comes next: if rates have dropped, your returns going forward shrink. It's especially relevant for people relying on bond or CD income, like retirees, when maturing money must be reinvested.
Real-life example
Imagine a CD paying 5% matures and hands back your money. If the best rate available now is only 3%, you're forced to reinvest at that lower level, cutting your future interest. These are rounded, hypothetical numbers to show the risk, not current rates you'd find today.
Common mistakes
- Assuming a maturing bond or CD is all upside because you got your money back.
- Overlooking reinvestment risk when building an income plan around bonds or CDs.
- Reaching for longer maturities only for higher rates, ignoring the flip side of interest-rate risk.
- Forgetting that regular interest payments also have to be reinvested, often at whatever rate exists then.
Pro tips
- Build a bond or CD ladder so only part of your money reinvests at any one time.
- Match maturities to when you'll need the cash to reduce forced reinvestment.
- Weigh reinvestment risk against interest-rate risk — they pull in opposite directions.
- Consider locking in longer terms if you want to secure today's rate for longer.

Frequently asked questions
When is reinvestment risk the biggest concern?
It matters most when interest rates are falling and you have bonds or CDs maturing. The money you get back must be reinvested at the new, lower rates, trimming your future income. Retirees and others who depend on interest payments feel it most, because their income can quietly drop as older, higher-paying holdings mature.
How is reinvestment risk different from interest-rate risk?
They're two sides of a coin. Interest-rate risk is the chance a bond's price falls when rates rise. Reinvestment risk is the chance you'll have to reinvest matured money or interest at lower rates when rates fall. Rising rates hurt current bond prices but help reinvestment; falling rates do the reverse.
Can a bond ladder help with reinvestment risk?
It can soften it. A ladder holds bonds or CDs that mature at staggered dates, so only a portion comes due at any one time. That way you're never forced to reinvest everything at a single low rate. Some maturities may land when rates are higher, spreading out the risk over time.
Knowing what Reinvestment Risk means is knowledge — the first half. A brick gets placed when you act on it: note when your CDs or bonds mature and think through where you'd reinvest if rates were lower then.
