What Is Credit Risk in Bonds?
Every bond is, at its core, a promise — a commitment from the issuer to pay interest on schedule and return principal at maturity — and credit risk is simply the chance that promise doesn’t get kept in full.
The short answer
Credit risk is the possibility that a bond issuer fails to make a scheduled interest payment, fails to repay principal at maturity, or both. It’s distinct from the day-to-day price swings caused by interest rate risk; credit risk is specifically about the issuer’s ability and willingness to pay, not about broader market rate movements. Bonds from issuers seen as less able to reliably pay generally have to offer a higher yield to attract buyers willing to accept that added uncertainty.
Where credit risk comes from
Every bond issuer — corporations, municipalities, and governments alike — carries some level of uncertainty about its future financial condition. A company might see revenue decline, take on too much other debt, or face an unexpected legal or operational setback that strains its ability to make payments. A municipality might face a shrinking tax base or unfunded obligations. Even issuers considered financially strong aren’t entirely free of this uncertainty, since financial conditions can change over the life of a long-term bond in ways that weren’t foreseeable when it was issued.
How credit ratings attempt to measure it
Credit rating agencies assign letter-grade ratings meant to summarize an issuer’s relative likelihood of making payments as promised, based on financial statements, industry conditions, debt levels, and other factors. These ratings are grouped broadly into investment-grade and speculative-grade, or high-yield, categories, with speculative-grade issuers generally viewed as carrying meaningfully more credit risk. A rating is an opinion about relative risk at a point in time, not a certainty about what will happen — ratings can be revised up or down as an issuer’s circumstances change, sometimes after a bond has already been purchased.
Where to research an issuer’s credit standing
Beyond published ratings, an issuer’s financial statements, debt load, and cash flow trends are publicly available for many corporate and municipal bonds and can offer additional context. Bond prospectuses typically disclose the issuer’s outstanding debt and other obligations that could compete with bondholders for repayment if finances got tight. Comparing an issuer’s debt levels and earnings trends against similarly rated peers can also help put a single rating into a broader context, rather than treating one number as the entire picture.
How credit risk shows up in pricing
- Higher yields for lower-rated issuers. A bond from a company or entity with a weaker credit profile generally has to offer more yield to compensate for the added uncertainty.
- Spread over safer benchmarks. The gap, or spread, between a given bond’s yield and that of a very highly rated bond is often used as shorthand for how much credit risk the market perceives.
- Sensitivity to news. Bonds from lower-rated issuers can react more sharply to news about the issuer’s finances than bonds from issuers seen as more stable.
The takeaway
Credit risk is fundamentally about whether an issuer can and will make good on its payment promises, and it’s a separate consideration from how bond prices move with interest rates generally. Ratings, spreads, and an issuer’s own disclosures each offer a partial view of this risk, and looking at more than one of them tends to give a fuller picture than relying on any single source, including default risk specific to corporate bonds.
