Credit Rating for Bank Loans vs Bonds

A credit rating for bank loans can differ substantially from a bond rating for the same borrower—sometimes by multiple notches. The gap exists because rating agencies treat loans and bonds as fundamentally different instruments: loans typically rank higher in bankruptcy, have better monitoring by active lenders, and benefit from less volatile trading dynamics, all of which push loan ratings higher. A company rated BB on bonds might be rated BB+ or even BBB− on its bank debt.

Why the Same Borrower Has Two Ratings

The fundamental reason is recovery. A credit rating measures default probability and, implicitly, loss severity. When a company enters distress, creditors are paid from the same pool of assets, but the order matters. Bank loans almost always sit above bonds in the capital structure—they are secured or senior unsecured, while bonds are subordinated by contract. In a bankruptcy:

• Loans typically recover 70–85 cents on the dollar, sometimes more if collateralized.
• Bonds recover 40–60 cents, often far less in deeply distressed scenarios.

If a borrower defaults, the loss incurred by a bondholder is much larger than the loss incurred by a lender. Rating agencies model this explicitly. A company facing a 2% probability of default with expected bond recovery of 45% has a higher loss magnitude than a 2% default scenario with loan recovery of 80%. So the agency assigns a better rating to the loan—not because the borrower is stronger, but because lenders’ claims are stronger.

Structural Seniority and Covenant Packages

Bank loans come with structural protections that bonds rarely have. A loan agreement includes:

• Collateral: Assets pledged to secure repayment.
• Covenants: Restrictions on debt levels, asset sales, capital expenditures, and cash flows. Breach triggers acceleration.
• Financial reporting: Monthly or quarterly, with audit rights.
• Lender syndication: Active relationships with multiple banks who monitor performance and can tighten terms quickly.

Bonds, by contrast, trade anonymously in capital markets. Bondholders are passive until the company misses a coupon. There are few covenants and little real-time monitoring. This structural difference translates into ratings uplift: the lender’s superior position in bankruptcy and superior information and control during performance justify a higher rating.

The magnitude of this gap varies. For stable, investment-grade borrowers, the difference might be 0.5 notches. For distressed, highly leveraged companies, lenders may rate the debt 1.5–2 full notches higher than bondholders would, reflecting the large gap in recovery assumptions.

Recovery Assumptions in Practice

Rating agencies publish recovery data by position and industry. For a typical industrial company in distress:

These figures reflect historical averages across defaults over decades. They embed the assumption that senior lenders will either restructure and recover most principal, or force an asset sale in bankruptcy that covers most of their claims. Junior creditors receive residuals.

An agency will use these recovery assumptions to map default scenarios to loss rates, then assign a rating. If loan recovery is guaranteed to be 80%, the agency can tolerate a higher default probability for the loan rating than for bonds, where recovery is only 50%.

Who Rates Loans vs Bonds

Moody’s, S&P, and Fitch all rate corporate bonds widely. But loan ratings are less universally published. Some syndicated bank loans do carry agency ratings, but many are rated privately by lenders themselves or specialized loan rating firms like LCD (part of Refinitiv) and CreditTrade. This creates an asymmetry: a large company’s bonds will have three public ratings; its bank debt may have only one or two, or none at all.

Institutional loan trading has grown, and some agencies have expanded loan rating coverage. But bond ratings remain the primary public signal of corporate credit quality. This means investors often see the bond rating and miss the meaningfully better loan rating—leading to potential undervaluation of the loan instruments.

Downgrades and Divergence

When a company hits trouble, loan ratings and bond ratings can diverge sharply. Suppose a recession hits and earnings fall 40%. The bond rating might drop from BB to B, while the loan rating stays at BB− or BB, because recovery assumptions improve (the company may survive at lower earnings). Lenders are less sensitive to earnings volatility; bonds are more sensitive because they depend entirely on the company’s survival and cannot rely on recovery upside.

Similarly, a covenant breach in a bank loan can force restructuring and senior lender recovery before a broader default occurs. The bonds never breach a covenant; they go unpaid in full default. The loan emerges with 85% recovery; the bonds with 35%. This ex-post divergence is often predictable ex-ante if you understand the seniority and structure.

Implications for Investors

For borrowers:

• Bank debt is cheaper and easier to place than bonds at similar default probabilities, because recovery is better. This is rational pricing.
• A gap between loan and bond spreads signals market expectation of distress—if spreads diverge sharply, loans rallied relative to bonds, implying creditors expect default and are pricing in differential recovery.

For investors:

• A bond’s rating should be discounted by 0.5–1.5 notches when compared directly to the loan rating. A BB bond and a BB− loan from the same issuer carry similar expected loss, not identical risk.
• If you own bonds, loan-to-value trends matter. As loan balances grow, bond recovery declines and the bond rating rating should be marked lower.
• In high-yield or distressed situations, ignore the headline rating. Scrutinize seniority, collateral, and recovery assumptions. A BB rating on a subordinated bond is riskier than a B rating on a senior loan.
