Junk bonds are bonds rated below investment grade, indicating higher credit risk. Also called high-yield or speculative-grade bonds, they generally offer higher yields than comparable investment-grade debt to compensate investors for a greater risk of missed payments or default.
The term describes credit quality. It does not mean the bond is worthless, that the issuer has already defaulted, or that its advertised yield is a guaranteed return.
For investors, the central question is whether the income and purchase price adequately compensate for the risk. For brokers, the challenge is presenting the bond’s rating, price, yield and contractual terms clearly enough for clients to understand the exposure.
What ratings make a bond “junk”?
The boundary depends on the rating agency’s scale. On the commonly used global long-term scales, the dividing line is:
| Classification | S&P Global | Moody’s |
|---|---|---|
| Investment grade | BBB− or higher | Baa3 or higher |
| Speculative grade / high yield | BB+ or lower | Ba1 or lower |
A downgrade from BBB− to BB+ crosses the investment-grade boundary on S&P’s scale. It does not, by itself, mean a payment has been missed.
Credit ratings are opinions about creditworthiness. They can change, different agencies can disagree, and separate bonds from one company can have different ratings because their guarantees, collateral or repayment priority differ. Check the rating of the actual issue, its agency and its date.
An unrated bond does not automatically have a junk rating. It lacks that rating assessment, so its credit risk needs to be evaluated through other evidence.
How do junk bonds work?
A corporate bond is a debt obligation. The company raises money and promises payments under the bond’s terms. A conventional fixed-rate bond specifies a coupon, a face value and a maturity date when principal becomes due.
For example, a bond with a USD 1,000 face value and an 8% annual coupon promises USD 80 of interest per year. Its market price can move above or below USD 1,000 while that fixed coupon remains unchanged.
Investors can buy at issuance or trade existing bonds in the secondary market. A secondary-market purchase transfers the bond between investors; it does not necessarily provide new money to the issuer. A broker-dealer may facilitate the transaction as an intermediary or trade from its own inventory.
Some companies issue speculative-grade bonds from the outset because of factors such as high debt, uncertain cash flows or a limited operating history. Others issued investment-grade bonds that were subsequently downgraded into high yield. These downgraded bonds are commonly called fallen angels. Bonds upgraded from high yield to investment grade are often called rising stars.
The credit label does not tell you every contract feature. Junk bonds may have fixed or floating payments, security over assets, early-redemption provisions or other terms that affect their risk and value.
Why do junk bonds offer higher yields?
Investors generally demand more compensation for lending to a borrower whose ability to repay is less certain. That compensation may appear in a higher coupon when the bond is issued or in a lower price when an existing bond trades.
The difference between a bond’s yield and a suitable benchmark yield is called a credit spread. Suppose a corporate bond yields 9% and a comparable government benchmark in the same currency yields 4%. The simple spread is five percentage points, or 500 basis points.
That spread is not a 5% probability of default. It can reflect several factors, including expected credit losses, liquidity and the compensation investors demand for uncertainty. Comparisons also need consistent maturities and yield measures; callable bonds may require adjustments for the issuer’s redemption option.
When investors become more concerned about an issuer, its bond price can fall and the quoted yield can rise. A higher yield can therefore accompany worsening prospects for getting paid.
Example: an 8% coupon and a 10% current yield
Consider a hypothetical bond with five years remaining until maturity:
- Face value: USD 1,000.
- Fixed annual coupon: 8%, or USD 80.
- Purchase price: USD 800.
The coupon rate is based on face value: USD 80 ÷ USD 1,000 = 8%.
The current yield is based on the purchase price: USD 80 ÷ USD 800 = 10%.
Both figures describe the same bond. The current yield is higher because the buyer pays less than face value, not because the issuer has increased the annual coupon.
The promised annual coupon stays the same at every price.
- Face value
- USD 1,000
- Fixed coupon rate
- 8% per year
Move the slider or use the arrow keys. All prices are in US dollars.
- Purchase price
- $80080.00% of par
- Annual coupon, if paid
- $808% of $1,000 face value
- Current yield
- 10.00%Annual coupon ÷ price
At a price of $800, the $80 annual coupon equals a 10.00% current yield.
Current yield is not total return. It excludes price changes, principal repayment and any missed payments.
Compare four purchase prices
| Price (USD) | Annual coupon (USD) | Current yield |
|---|---|---|
| $400 | $80 | 20.00% |
| $800 | $80 | 10.00% |
| $1,000 | $80 | 8.00% |
| $1,200 | $80 | 6.67% |
Illustration only. Assumes a purchase on a coupon date with no accrued interest. Fees and taxes are excluded. This does not calculate yield to maturity or predict default.
Current yield ignores what happens to the bond’s price and whether the promised cash flows arrive. It also leaves out the difference between the purchase price and the amount repaid at maturity.
What does the investor actually earn?
Assume the example bond pays its coupon annually. An investor buys just after a coupon date for USD 800, receives the next USD 80 coupon, and sells just after that payment one year later for USD 750.
One-year result = USD 80 coupon + USD 750 sale proceeds − USD 800 purchase price = USD 30.
Holding-period return = USD 30 ÷ USD 800 = 3.75%.
The 10% current yield at purchase did not become a 10% total return because the sale price fell.
Now consider a separate default scenario. If the investor receives no coupon and ultimately recovers only USD 400, the loss against the USD 800 purchase price is USD 400, or 50%. Recovery timing is unspecified, so this is a total loss calculation, not an annualised return. The USD 400 recovery is an assumption, not a typical recovery rate or a minimum protection.
These examples exclude commissions, spreads, taxes and reinvestment. The performing-bond purchase and sale occur on coupon dates, avoiding accrued-interest adjustments. They illustrate arithmetic rather than an actual security or market quote.
Current yield, yield to maturity and yield to worst
A platform should identify which yield it displays. These measures answer different questions:
| Measure | What it describes | What it does not guarantee |
|---|---|---|
| Current yield | Annual coupon divided by the current bond price | The result after price changes, default or maturity repayment |
| Yield to maturity (YTM) | The discount rate that equates the purchase price with scheduled coupons and principal through maturity | That the issuer will pay every cash flow or that realised returns will match the calculation |
| Yield to worst (YTW) | The lowest calculated yield among the relevant contractual redemption scenarios, including applicable calls | A floor on losses if the issuer defaults |
FINRA’s explanation of bond yields and returns describes why a yield calculation and the investor’s eventual result can differ.
For a distressed bond, a strikingly high quoted YTM may rely on payments the market doubts will arrive. The calculation should be read alongside the issuer’s finances and the specific bond terms.
What are the main risks of junk bonds?
Default and recovery risk
The issuer may fail to make an interest payment or repay principal. Restructuring can change payment terms or replace the original claim with other assets. Recovery depends on the issuer’s remaining value, the legal process and the bond’s position among competing claims.
Being senior to shareholders does not guarantee a full recovery. Secured, senior unsecured and subordinated bonds can have different outcomes. The SEC’s overview of high-yield bond risks explains the importance of credit risk and payment priority.
Price and interest-rate risk
A bond can lose market value without defaulting. Rising benchmark rates or a widening credit spread can reduce its price. An improvement in credit conditions can support prices, but an upgrade does not guarantee a profitable trade.
Holding to maturity avoids the need to accept an interim sale price only if the investor can keep holding. It does not remove the issuer’s repayment risk.
Liquidity risk
Some issues trade infrequently. The last recorded trade or an estimated valuation may differ from the price available for the investor’s actual order size. During market stress, finding a buyer can become harder and bid–ask spreads can widen.
Call and reinvestment risk
A callable bond allows early redemption under specified terms. If refinancing becomes attractive to the issuer, investors may receive their money back sooner than expected and struggle to replace the income at a comparable yield.
A purchase above the eventual call price can also affect the investor’s return. The call schedule matters alongside the final maturity date.
Currency risk
A foreign-currency bond adds exchange-rate exposure. Its coupons and repayment may retain their value in the bond’s currency while being worth less in the investor’s home currency. Currency hedging, where available, has costs and its own terms.
Individual junk bonds vs high-yield bond funds
An individual bond exposes its holder to the terms and credit risk of a particular debt issue. Analysing it requires attention to the issuer, seniority, covenants, maturity and trading liquidity.
A high-yield mutual fund or ETF holds a portfolio of bonds. This can spread exposure across issuers, but it does not remove market-wide credit risk. Fees, portfolio concentration, liquidity and the fund’s investment mandate still matter.
Owning fund shares also differs from owning a bond with a stated face value and maturity. Most conventional bond funds keep replacing holdings and do not promise to repay the original share purchase price on a particular date. Target-maturity funds have a different structure, but still do not guarantee that an investor will recover the amount paid.
Fund distributions, a portfolio yield figure and total return are separate measures. A large distribution does not establish that the fund’s share price or the investor’s capital is protected.
What should investors examine before buying?
Start with the bond’s prospectus or offering document and current issuer disclosures. Useful questions include:
- Ability to pay: does operating cash flow support interest payments, and how much debt needs refinancing soon?
- Position in the capital structure: is this issue secured, senior or subordinated, and which entities provide guarantees?
- Contract protections: what do the covenants allow, and what happens if they are breached?
- Price and yield: which yield measure is quoted, and what cash-flow assumptions does it use?
- Exit and redemption: what are the minimum trade size, executable bid, maturity and call schedule?
- Portfolio exposure: how much already depends on the same issuer, sector, currency or economic conditions?
These questions help frame an assessment; neither a single rating nor a high yield replaces the underlying credit analysis.
What matters when a broker offers high-yield exposure?
The first distinction is the instrument itself. A cash bond, shares in a high-yield ETF and a CFD referencing a related instrument give the client different rights. A CFD position does not itself make the customer a creditor of the bond issuer.
For a cash-bond offering, the trade ticket and supporting systems need to represent the actual issue: identifier, currency, denomination, maturity, coupon schedule, rating information and any call provisions.
Bond pricing conventions need particular care. A quote of 80 commonly means 80% of par, or USD 800 for USD 1,000 face value. In markets using clean prices, accrued interest and applicable fees affect the final settlement amount. The displayed yield should also identify its calculation basis. FINRA’s bond pricing guide explains these quotation conventions.
Execution and account records need to cover order size, quote freshness, coupon payments, redemptions and any default or restructuring events. Those events should map into the brokerage’s back office and customer statements. An indicative valuation should not be presented as an executable bid.
When evaluating a trading platform, verify the precise bond or fund workflow required, including custody and external trading connections. Support for other asset classes does not establish that cash high-yield bonds are available. Client eligibility, disclosures and any suitability or appropriateness requirements depend on the jurisdiction and service.
