Simple definition
A junk bond, also called a high-yield bond, comes from an issuer that rating agencies judge to be lower quality. To attract buyers despite a greater chance the issuer won't repay, it pays higher interest. Think of it as lending to a borrower with a shaky credit history: you can earn more, but the risk of not being paid back is real.
Why it matters
Junk bonds tempt investors with bigger payments, but that yield is compensation for higher default risk, not a free lunch. In a downturn, lower-rated issuers are the first to struggle. Understanding the trade-off keeps you from chasing income into losses you didn't expect.
Real-life example
Picture two bonds: a top-rated one paying 4% and a junk-rated one paying 8%. The extra 4 percentage points is the market's price for the higher chance the junk issuer misses payments. These are rounded, made-up figures to show the trade-off, not current rates on any real bond.
Common mistakes
- Chasing the high yield without weighing the greater chance the issuer defaults.
- Assuming a junk bond is fine as long as it hasn't missed a payment yet.
- Putting emergency or short-term money into junk bonds instead of safe holdings.
- Ignoring that junk bonds often fall hardest exactly when the economy weakens.
Pro tips
- Treat a high yield as a warning about risk, not just a reward.
- Spread junk exposure across many issuers, often through a fund, to soften any single default.
- Keep junk bonds a small slice of a portfolio, not its foundation.
- Check the issuer's credit rating and read why it sits below investment grade.

Frequently asked questions
Why are they called junk bonds?
The nickname comes from their low credit ratings — below the investment-grade line that agencies use to mark relatively safe issuers. "Junk" signals a meaningfully higher chance of default, not that the bond is worthless. Issuers offer higher interest, which is why they're also called high-yield bonds, to make up for that added risk.
Are junk bonds ever worth buying?
They can play a small role for investors who understand and accept the higher risk in exchange for more income. The danger is concentration: a single junk issuer that defaults can wipe out years of extra yield. Many people who want the exposure use a diversified high-yield fund rather than picking individual bonds.
How risky are junk bonds compared with stocks?
Junk bonds sit between safe bonds and stocks on the risk scale. They're steadier than most stocks in calm times but can fall sharply in downturns, when weaker issuers struggle to pay. Unlike a Treasury, a junk bond carries genuine default risk, so it behaves less like a safe haven and more like a risk asset.
Knowing what Junk Bond means is knowledge — the first half. A brick gets placed when you act on it: check whether any bond fund you own holds high-yield or junk bonds and how large that slice is.
