Junk Bonds (High-Yield Bonds)

Quick Definition

Junk bonds — formally called high-yield bonds — are corporate bonds rated below investment grade: BB+/Ba1 or lower by S&P/Fitch and Moody's respectively. They offer higher interest rates than investment grade bonds to compensate investors for the elevated probability of default. The term "junk" carries a negative connotation, which is why the industry prefers "high yield," but both terms describe the same asset class: below-investment-grade corporate debt that yields 4-10% or more above US Treasury rates.

What It Means

Not all companies can borrow at investment grade terms. Startups, highly leveraged companies, cyclical businesses, and firms with below-average financial strength cannot obtain BBB- ratings — yet they still need debt financing. Junk bonds provide that access to capital markets, at a price: higher interest rates reflecting the higher probability the company cannot repay.

The high-yield market emerged as a recognized asset class in the 1970s and 1980s, largely through the work of Michael Milken at Drexel Burnham Lambert. Milken argued that diversified portfolios of high-yield bonds delivered returns that more than compensated for their higher default rates — a claim that proved largely correct over time, though Milken himself was later convicted of securities fraud.

Today the US high-yield market totals approximately $1.4 trillion in outstanding bonds, with a global market exceeding $2 trillion. It finances everything from cable companies and healthcare businesses to leveraged buyouts and energy companies.

The Investment Grade / Junk Divide

The line between investment grade and junk is the most consequential rating boundary in bond markets:

Crossing this line in either direction causes dramatic market effects:

Downgrade to junk (Fallen Angel):

• Institutional investors with investment-grade-only mandates must sell
• Forced selling pressure depresses bond prices
• Cost of new borrowing jumps
• Company may face liquidity stress

Upgrade to investment grade (Rising Star):

• New institutional buyers eligible to purchase
• Demand surge pushes prices up
• Borrowing costs fall significantly
• Credit profile validated

Junk Bond Rating Categories

Not all junk is equal. The high-yield spectrum spans a wide range of credit quality:

BB-rated bonds are sometimes called "crossover" credits — many are former investment grade companies that could return to IG status. CCC bonds are a different animal: distressed credits where recovery of principal is genuinely uncertain.

Historical Default Rates and Returns

The empirical case for high-yield investing rests on data:

Default Rates by Rating (Annual Average, 1983-2023)

Annual Returns: High Yield vs. Other Asset Classes

High yield bonds have historically delivered equity-adjacent returns with significantly lower volatility than stocks — especially when held through diversified funds that absorb individual defaults.

How Junk Bonds Are Used

1. Leveraged Buyouts (LBOs)

Private equity firms acquire companies using a combination of equity and high amounts of debt — much of it high-yield bonds. The target company's assets and cash flows support the debt load.

Classic LBO example:

• PE firm acquires company for $1 billion
• $300M equity + $700M debt (of which $400M is high-yield bonds)
• Company must generate sufficient cash flow to service the high-yield debt
• If successful, PE firm exits at a higher valuation; bondholders earn their yield

2. Growth Financing

Companies in early stages of growth or capital-intensive industries (cable, telecom, energy) that cannot yet achieve investment grade ratings use high-yield bonds to finance expansion.

3. Refinancing

Companies replace expensive bank debt or maturing bonds with high-yield issuance, often locking in multi-year financing.

4. Distressed Financing

Companies already in financial stress may issue deeply discounted high-yield bonds to raise emergency capital, often with very high yields (10-15%+) reflecting the elevated risk.

Junk Bond Spreads as Economic Indicator

High-yield credit spreads (the premium above Treasury yields) are a powerful real-time economic signal:

Historical examples:

• October 2008 (Financial crisis): HY spreads hit ~1,900 basis points (19% above Treasuries)
• March 2020 (COVID): Spreads hit ~1,100 basis points in days
• Normal 2019: Spreads around 350-400 basis points
• 2021 post-COVID recovery: Spreads compressed to ~300 basis points (very tight)

Spreads spiking rapidly often precede stock market declines — credit markets frequently lead equity markets as a warning signal.

Investing in Junk Bonds

Individual Bonds vs. ETFs/Funds

For retail investors, high-yield ETFs are almost always preferable to individual junk bonds:

Popular high-yield ETFs:

• HYG (iShares iBoxx High Yield): Most liquid; broad HY market
• JNK (SPDR Bloomberg HY Bond): Competitor to HYG; slightly different index
• USHY (iShares Broad High Yield): Broader, lower-cost alternative

The Fallen Angel Opportunity

Fallen angels — bonds recently downgraded from IG to junk — are a studied opportunity. Research shows:

1. Forced selling by IG-mandate holders depresses prices below fundamental value
2. HY-mandate investors are slow to absorb the supply
3. Over the following 12-24 months, prices often recover as HY investors establish positions
4. If the company improves and gets upgraded back to IG (rising star), further price appreciation occurs

FALN ETF (iShares Fallen Angels USD Bond) specifically targets this fallen angel effect.

Key Points to Remember

• Junk bonds (high-yield bonds) are rated below BBB-/Baa3 — they offer higher yields in exchange for higher default risk
• The US high-yield market is approximately $1.4 trillion — a significant and investable asset class
• BB-rated bonds (upper high yield) have relatively modest default rates; CCC bonds are highly speculative
• High-yield spreads are an important economic indicator — widening signals rising recession and default risk
• Historically, diversified high-yield portfolios have delivered returns between investment grade and equities — an attractive risk/return profile for some allocations
• Fallen angels — recently downgraded IG bonds — often represent buying opportunities due to forced selling

Common Mistakes to Avoid

• Chasing yield without understanding credit risk: A 9% yield is worthless if the bond defaults and you recover 40 cents on the dollar
• Buying individual junk bonds: Without the ability to analyze complex credit situations, concentrated exposure to single issuers is highly risky — use diversified funds
• Ignoring liquidity risk: High-yield bonds can be illiquid in stress periods — bid-ask spreads widen dramatically during market panics, and selling at a fair price becomes difficult
• Treating CCC and BB as the same: The CCC category has default rates 20x higher than BB — they are completely different risk propositions despite both being "junk"

Frequently Asked Questions

Q: Are junk bonds a good investment? A: For diversified portfolios seeking income above investment grade rates, a modest allocation to high-yield bonds (via ETFs) has historically added value. They are not for conservative investors or those who cannot tolerate significant short-term price swings. A high-yield bond fund can lose 25-35% of its value in a severe recession (2008, early 2020) before recovering. They are best suited to investors with long time horizons who can weather volatility.

Q: Why do companies issue junk bonds instead of getting bank loans? A: High-yield bonds offer several advantages over bank loans: longer maturities (5-10 years vs. 3-5 for leveraged loans), no required collateral for unsecured bonds, fixed rates that hedge against rising rates, and covenants that are typically more borrower-friendly than bank loans. For large financing needs ($500M+), the bond market provides more capacity than single-bank relationships.

Q: What is the difference between junk bonds and distressed debt? A: All distressed debt is high-yield, but not all high-yield is distressed. "Distressed" typically refers to bonds trading at 70 cents on the dollar or below (yields above 10-12% above Treasuries), signaling market belief that default is likely or already occurring. Distressed investing is a specialized strategy involving legal expertise in bankruptcy proceedings, recovery analysis, and often taking control of reorganized companies — far more complex than owning a diversified high-yield ETF.
