Junk Bond

Definition

A junk bond (formally called a high-yield bond) is a corporate debt security rated below investment grade — BB+ or lower by S&P and Fitch, or Ba1 or lower by Moody's — meaning the issuing company has a significantly higher probability of defaulting on its interest or principal payments, and investors demand a higher yield to compensate for this elevated credit risk.

How It Works

The Credit Rating Scale

Credit rating agencies assess the likelihood that a bond issuer will meet its payment obligations:

The dividing line between investment grade and junk is BBB-/Baa3. A downgrade from BBB- to BB+ is called a "fallen angel" event and often triggers forced selling, since many institutional investors (pension funds, insurance companies) are prohibited from holding sub-investment-grade debt.

The High-Yield Spread

Junk bond yields are quoted as a spread over government bonds (the "risk-free" rate). This spread compensates investors for:

• Default risk: the probability of losing some or all principal
• Recovery risk: if default occurs, bondholders typically recover only 30-50% of face value
• Liquidity risk: junk bonds trade less frequently than government or investment-grade bonds
• Volatility risk: junk bond prices fluctuate more with economic conditions

Typical high-yield spreads:

(1 basis point = 0.01%)

Historical Default Rates

Moody's long-term data shows cumulative default rates over 5 years:

• Ba-rated: ~8-10%
• B-rated: ~20-25%
• Caa-rated: ~45-55%

These are averages across economic cycles. During recessions, annual default rates spike to 10-15% for the overall high-yield market.

Example

Tomasz is considering two bonds for his portfolio:

Bond A — Polish government 10-year bond (rated A/A2)

• Face value: 10,000 PLN
• Coupon: 5.25%
• Yield to maturity: 5.50%
• Annual income: 525 PLN

Bond B — Hypothetical Polish mid-cap company bond (rated BB)

• Face value: 10,000 PLN
• Coupon: 9.00%
• Yield to maturity: 9.50%
• Annual income: 900 PLN
• Credit spread: 400 bps over government bonds

Return comparison over 5 years (assuming no default):

Tomasz earns 1,519 PLN more after tax by choosing the junk bond. But what if the company defaults?

Default scenario (year 3, with 40% recovery):

• Coupons received (years 1-2): 1,800 PLN
• Recovery on principal: 4,000 PLN (40% of 10,000)
• Total received: 5,800 PLN
• Loss: 4,200 PLN (10,000 invested - 5,800 recovered)

One default wipes out more than two years of extra income. This is why diversification is essential in high-yield investing — you need enough bonds so that the extra yield from performing bonds covers the losses from defaults.

The Breakeven Math

If junk bonds yield 4% more than government bonds and the average recovery rate is 40%, the portfolio can tolerate an annual default rate of up to:

Breakeven default rate = Spread / (1 - Recovery Rate) = 4% / 60% = 6.67%

If fewer than 6.67% of bonds default annually, the high-yield portfolio outperforms. Historically, the average annual default rate has been ~3-4%, meaning the high-yield market has compensated investors for default risk on average — but not in every year.

Why It Matters for Investors

High Yield as an Asset Class

The European high-yield market is approximately 400 billion EUR in size. Major issuers include companies in telecom (Altice, Iliad), industrials (Ardagh, Smurfit Kappa pre-upgrade), and services. The iBoxx EUR Liquid High Yield index tracks this market.

For Polish investors, exposure to European high-yield is most easily obtained through ETFs like the iShares Euro High Yield Corporate Bond UCITS ETF (IHYG), which holds ~600 bonds and provides diversification that individual bond purchases cannot match.

Correlation Profile

High-yield bonds behave like a hybrid between bonds and equities:

• In calm markets, they trade like bonds (driven by yield and interest rates)
• In stressed markets, they trade like equities (driven by credit risk and default fears)

This means junk bonds provide less diversification benefit than government bonds in a portfolio downturn — exactly when you need diversification most.

Fallen Angels vs. Rising Stars

A fallen angel is a formerly investment-grade company downgraded to junk. These bonds often trade at depressed prices due to forced institutional selling, creating opportunities for high-yield investors. Historically, fallen angel bonds have outperformed the broader high-yield index.

A rising star is a junk-rated company upgraded to investment grade. This triggers a price jump as institutional buyers can now hold the bonds, rewarding early investors.

Risks and Pitfalls

Reaching for Yield

The most dangerous mistake in fixed income is buying increasingly risky bonds to chase higher yields. During periods of low interest rates (2015-2021 in Europe), many retail investors loaded up on CCC-rated bonds yielding 8-10% because savings accounts paid nothing. When the economic cycle turned, losses exceeded years of extra income.

Illiquidity in Stress

Individual junk bonds can become virtually untradeable during market stress. Bid-ask spreads that are normally 0.5-1.0% can widen to 5-10% or more. ETFs provide better liquidity but can trade at discounts to their net asset value during severe stress (as happened briefly in March 2020).

Interest Rate Sensitivity Is Lower — but Not Zero

Junk bonds have shorter duration than investment-grade bonds (typically 3-5 years vs. 7-10 years) because their higher coupons return cash faster. This means less sensitivity to interest rate changes. However, when credit spreads widen and interest rates rise simultaneously (as in 2022), junk bonds get hit from both sides.

Covenant Erosion

In the low-rate era, bond covenants (legal protections for investors) weakened significantly. Many recent high-yield issuances are "covenant-lite," giving companies more freedom to take on additional debt, pay dividends to shareholders, or strip assets — all of which increase risk for existing bondholders.

Sector Concentration

The European high-yield market is concentrated in a few sectors. A downturn in telecom or energy can disproportionately affect high-yield indices. Individual bond selection requires deep credit analysis — most retail investors should use diversified ETFs rather than picking individual junk bonds.

FAQ

Why are they called "junk" bonds? The term dates to the 1980s when Michael Milken at Drexel Burnham Lambert popularized financing leveraged buyouts and speculative companies with below-investment-grade debt. Critics called them "junk" to highlight the risk. The industry prefers "high-yield" — same product, better marketing.

Should I own high-yield bonds if I already own equities? The diversification benefit is limited because high-yield bonds correlate closely with equities during downturns (correlation rises to 0.7-0.8 in crises). If you want bond diversification, investment-grade government bonds are more effective. High-yield makes sense as a return enhancer if you want equity-like returns with slightly lower volatility.

How do I evaluate a single junk bond? Key metrics include: interest coverage ratio (EBIT / interest expense — should be >2x), net debt / EBITDA (ideally <4x), free cash flow generation, maturity wall (when major debts come due), and the company's ability to refinance. For most retail investors, analyzing individual credits is impractical — use ETFs instead.

What happens to my junk bond ETF in a recession? Expect price declines of 10-20% as spreads widen and some underlying bonds default. The ETF provider removes defaulted bonds from the index and the portfolio. Your NAV drops, but the higher yields from surviving bonds gradually compensate. Recovery to pre-recession levels typically takes 1-3 years. Selling during the trough locks in losses.
