Junk bonds are corporate bonds rated below investment grade, meaning the issuer has a meaningfully higher chance of missing interest or principal payments than a typical blue-chip borrower. To offset that risk, they pay higher interest than Treasuries or investment-grade corporate debt. The dividing line is set by the major rating agencies: anything at or below BB+ (Standard & Poor’s and Fitch) or Ba1 (Moody’s) is speculative grade, which is the polite name for junk.
Where the Investment-Grade Line Sits
Three firms dominate the ratings business: Standard & Poor’s, Moody’s Investors Service, and Fitch Ratings. Each evaluates a bond issuer’s cash flow, debt levels, profit margins, and competitive position, then assigns a letter grade reflecting the likelihood the company keeps paying.1S&P Global. Understanding Credit Ratings
The rating is an opinion, not a guarantee. What makes the investment-grade line so important is that many pension funds and insurance companies are prohibited by their own rules from holding anything below it. When a bond crosses that boundary, a large pool of buyers disappears, and prices react accordingly.
S&P and Fitch use identical letters. Investment grade runs from AAA down to BBB-. Speculative grade begins at BB+ and works its way down.1S&P Global. Understanding Credit Ratings Moody’s uses a parallel scale where investment grade runs Aaa to Baa3 and speculative grade begins at Ba1.2Moody’s Investors Service. Moody’s Ratings System
Not all junk is created equal. Within speculative grade, the risk spans a wide range:
- Upper speculative (BB+/Ba1 through BB-/Ba3): the issuer has some financial cushion but faces meaningful uncertainty.
- Highly speculative (B+/B1 through B-/B3): the issuer is vulnerable to adverse business or economic conditions.
- Substantial risk (CCC+/Caa1 and below): the issuer is currently vulnerable and depends on favorable conditions to keep paying.
- Default (D/C): the issuer has already missed payments or filed for bankruptcy.
Ratings can change at any time. Agencies monitor issuers continuously and upgrade or downgrade in response to new earnings data, industry shifts, or changes in the debt load.
Why Junk Bonds Pay More
The premise is straightforward: you accept more credit risk, and the issuer compensates you with a higher coupon. The gap between the yield on a junk bond and the yield on a comparable-maturity Treasury is called the credit spread. As of early March 2026, the average spread across the U.S. high-yield market was about 313 basis points (3.13 percentage points) above Treasuries.3FRED: St. Louis Fed. ICE BofA US High Yield Index Option-Adjusted Spread
That figure reflects a relatively calm market. In recessions or financial crises, spreads can blow out to 800, 1,000, or higher as investors flee risky debt. The spread has to cover real losses. Investment-grade bonds default at rates below 0.1% annually. High-yield bonds have historically averaged default rates around 4.5% per year, with individual years ranging from under 2% to over 11%.4Federal Reserve Bank of New York. Understanding Aggregate Default Rates of High Yield Bonds The extra yield has to absorb those losses and still leave you ahead.
Who Issues Junk Bonds and Why
Two very different types of companies end up in the high-yield market, and the issuer’s story matters as much as the rating.
Younger, fast-growing companies are frequent issuers. A tech firm or expanding retailer might have strong revenue growth but lack the years of stable earnings that would earn an investment-grade stamp. Rather than sell equity and give up ownership, the founders issue bonds at a higher interest rate. The bet is that the business will grow into its debt load.
Established companies also land in junk territory after taking on heavy debt for a specific purpose. Leveraged buyouts are the classic example: a private equity firm acquires a company using borrowed money, and the resulting balance sheet pushes the firm’s rating into speculative range. Companies also issue high-yield bonds to refinance maturing debt when they lack access to cheaper bank lending. In these cases, the rating reflects current financial leverage, not a judgment about the underlying business. A well-run company can carry a junk rating simply because it carries a lot of debt relative to earnings.
Fallen Angels and Rising Stars
A fallen angel is a bond that originally carried an investment-grade rating and was later downgraded into junk. The downgrade usually follows financial distress, and it forces selling by institutions whose mandates bar speculative-grade holdings. That wave of forced sales can push prices below what the fundamentals justify.5European Central Bank. Understanding What Happens When Angels Fall
A rising star is the opposite: a speculative-grade bond climbing toward an investment-grade upgrade. Investors who buy before the upgrade often see price appreciation, because crossing back into investment grade opens the bond up to a much larger pool of institutional buyers.
The Risks Beyond Default
Default risk gets the attention, but it isn’t the only thing that can cost you money.
Liquidity Risk
Junk bonds are harder to sell quickly than investment-grade bonds or stocks. The market is smaller, individual issues trade less frequently, and during periods of stress, buyers can vanish. OECD data shows that even investment-grade corporate bonds had median bid-ask spreads of 30 basis points at the end of 2025, and that non-investment-grade bonds face additional liquidity costs that show up as longer trading delays.6OECD. Corporate Debt Market Outlook in a Transforming World If you need to sell during a downturn, expect a haircut.
Interest Rate and Reinvestment Risk
When rates rise, bond prices fall. Junk bonds are less sensitive to rate moves than investment-grade debt because their prices are driven more by credit risk than by rate changes. They behave partly like bonds and partly like stocks. But if the economy weakens and rates drop, junk prices may not rally as much as Treasuries, because investors are simultaneously worried about survival through a recession. And if your bond gets called during a low-rate environment, you face the challenge of reinvesting your principal at a comparable yield.
What Recovery Looks Like After a Default
A default occurs when the issuer misses a scheduled interest or principal payment. Indentures typically include a grace period of around 30 days for interest before the miss becomes a formal event of default. Principal payments usually have no grace period.
If the company liquidates, creditors are paid in a strict hierarchy: secured senior lenders first, then unsecured senior debt, then subordinated debt, then equity. Most junk bonds sit in the unsecured or subordinated tiers, behind the bank lenders. The NAIC reported that the weighted average recovery rate on defaulted high-yield bonds was about 57% of par value, compared to 83% for senior bank loans.7NAIC. US Corporate Bond Default and Recovery Rates Those are averages. Individual recoveries run from near zero for deeply subordinated bonds in asset-light companies to 70% or more for senior secured high-yield issues. A manufacturer with real estate and equipment generally produces better recoveries than a services firm whose value walks out the door every night.
What to Read in the Indenture Before You Buy
Every bond comes with an indenture, the legal contract between the issuer and bondholders. For junk bonds, the fine print matters more than for safer debt because the protections written into the contract may be your best defense if things deteriorate.
The indenture sets the maturity date, the coupon rate, and any call provisions. A call provision lets the issuer redeem the bond early, typically after a non-call period of several years, by paying a premium above par. Issuers tend to call bonds when interest rates drop, which means you get your money back precisely when reinvesting at the same yield becomes hardest.
Covenants
High-yield indentures typically include incurrence covenants, which kick in only when the company tries to take a specific action that would cross a financial threshold. The most common restrictions limit additional borrowing, restrict dividend payments to shareholders, and cap certain investments or acquisitions.8Federal Reserve Bank of Boston. High-Yield Debt Covenants and Their Real Effects Weak covenants leave bondholders exposed if management piles on more debt or drains cash to equity holders.
Yield to Maturity, Not Coupon
The coupon tells you the fixed annual payment. Yield to maturity tells you the actual annualized return if you hold to the maturity date, accounting for whether you bought above or below par. Junk bonds frequently trade well away from par, so YTM is the number to compare across bonds. A 7% coupon trading at 90 cents on the dollar has a significantly higher YTM than the same coupon at par.
How Junk Bond Income Is Taxed
Interest from junk bonds is taxed as ordinary income at your marginal federal rate, the same as any other corporate bond interest. There is no special tax benefit for taking on more credit risk, which makes the after-tax yield less attractive than the headline number suggests, especially in higher brackets.
Original Issue Discount
Many junk bonds are issued below par value, creating what the IRS calls original issue discount. The tax code requires you to include a portion of that discount in gross income each year, even though you haven’t received the cash yet.9Office of the Law Revision Counsel. 26 USC 1272 – Current Inclusion in Income of Original Issue Discount That phantom income creates a real tax bill on money accruing on paper from an issuer whose creditworthiness is already questionable. The offsetting benefit is that each year’s OID inclusion increases your cost basis, reducing your taxable gain or increasing your deductible loss when you sell or the bond matures.10IRS. Publication 1212 – Guide to Original Issue Discount (OID)
Capital Losses
If you sell a junk bond for less than your adjusted basis, or the bond becomes worthless in a default, the loss is a capital loss. Capital losses offset capital gains dollar for dollar. Excess losses can offset up to $3,000 of ordinary income per year ($1,500 if married filing separately), with unused losses carrying forward indefinitely.11Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses For a bond trading at distressed prices, you have to actually sell to realize the loss. An unrealized decline doesn’t count.
How to Buy Them
You can buy individual junk bonds through a brokerage account, but the drawbacks are real. Bonds trade in denominations of $1,000 par value with many brokerages requiring $5,000 or higher minimums, and the liquidity problem means you may pay a meaningful spread between the buy and sell price. Building a diversified individual portfolio requires substantial capital and the expertise to analyze each issuer.
For most investors, high-yield bond funds are the practical entry point:
- High-yield bond ETFs trade throughout the day at market prices, typically carry lower expense ratios, and offer immediate diversification across dozens or hundreds of issuers. During market stress, ETF prices can temporarily diverge from the underlying bond values.
- High-yield bond mutual funds price once daily at the end-of-day net asset value, which eliminates intraday swings but limits flexibility. Expense ratios tend to be higher than comparable ETFs, and some funds charge sales loads.
Both fund types spread your money across many issuers, so a single default doesn’t wipe you out. The trade-off is that you give up the ability to select specific bonds or hold to a defined maturity. The manager makes those calls, and the fund itself has no maturity date. Target-date high-yield funds, which hold bonds maturing in a specific year and then wind down, offer a middle ground.
