Bank Ratings

Bank ratings include public credit opinions on banks and their obligations as well as confidential supervisory assessments such as CAMELS.

Bank ratings are assessments of a bank’s creditworthiness, financial condition, or supervisory risk. The term can refer to public credit ratings assigned to a bank or one of its obligations, or to confidential ratings assigned by banking supervisors. Those ratings use different scales, evidence, and purposes.

Key Takeaways

  • A bank issuer rating, deposit rating, bond rating, and counterparty rating can differ for the same institution.
  • U.S. CAMELS ratings are confidential supervisory assessments, not public credit ratings.
  • CAMELS uses a 1-to-5 scale, with 1 strongest and 5 most critically deficient.
  • Credit-rating letter grades do not map directly to CAMELS numbers.
  • A rating is a dated opinion or supervisory assessment, not a guarantee of repayment, deposit access, or bank survival.

Main Types of Bank Ratings

Rating typeWhat it assessesTypical userUsually public?
Bank issuer ratingGeneral ability of the bank or holding company to meet financial obligationsBond investors and counterpartiesYes
Deposit ratingExpected repayment risk for deposits, under the agency’s methodologyDepositors and wholesale fundersOften
Instrument ratingCredit risk of a specific senior, subordinated, covered, or hybrid securitySecurity investorsYes
Counterparty ratingCapacity to perform on financial contractsDerivatives and trading counterpartiesOften
Supervisory ratingOverall condition and risk based on examination and supervisory evidenceRegulators and bank managementGenerally no

Always identify the rated entity and obligation. A parent holding company’s subordinated debt can have a different rating from an operating bank’s deposits.

CAMELS Supervisory Ratings

In the U.S. Uniform Financial Institutions Rating System, examiners assess:

  • C: capital adequacy
  • A: asset quality
  • M: management
  • E: earnings
  • L: liquidity
  • S: sensitivity to market risk

Each component and the composite rating use a numeric scale:

RatingGeneral supervisory meaning
1Strong; lowest supervisory concern
2Satisfactory
3Less than satisfactory
4Deficient
5Critically deficient; highest supervisory concern

The composite is not simply an arithmetic average. Supervisors apply judgment to the institution’s overall condition, risk profile, and management.

CAMELS ratings and examination reports are nonpublic supervisory information. A bank generally cannot treat its CAMELS rating as a marketing claim or disclose it to an unrelated third party without the appropriate permission.

Public Credit Ratings

Public credit ratings generally focus on the probability and severity of nonpayment under an agency’s methodology. Analysis may include:

  • capitalization and leverage
  • asset quality and credit concentration
  • earnings stability
  • liquidity and funding
  • business model and franchise
  • risk appetite and governance
  • operating environment
  • expected government or group support where the methodology recognizes it
  • the seniority and loss-absorption terms of a specific obligation

Rating agencies use different symbols and definitions. A grade from one agency should not be converted mechanically into another agency’s scale.

Worked Example

Assume Bank A has:

  • a public issuer credit rating
  • a higher-rated secured or covered obligation
  • a lower-rated subordinated Tier 2 bond
  • a confidential CAMELS composite rating

These results are not contradictory. The instrument ratings reflect claim priority and expected loss, while CAMELS reflects supervisory assessment of the bank’s overall condition. The confidential CAMELS score cannot be inferred reliably from public letter grades.

Bank Rating vs. Deposit Insurance

A credit rating and deposit insurance answer different questions.

  • A credit rating expresses an opinion about credit risk under its methodology.
  • Deposit insurance is a legal protection for eligible deposits, subject to coverage limits, account ownership rules, and the applicable scheme.

A highly rated bank can fail, and an insured depositor’s protection does not depend solely on a public bank rating. Depositors should verify coverage directly with the relevant insurer or regulator.

How Ratings Change

A rating can move because of:

  • rising credit losses or nonperforming assets
  • weaker capital or earnings
  • deposit outflows or wholesale-funding pressure
  • concentrated exposures
  • operational, compliance, or governance failures
  • acquisitions or changes in group support
  • sovereign or operating-environment deterioration
  • changes in rating methodology

An outlook or watch is not the same as a rating change. It signals possible direction or heightened review under the agency’s definitions.

How to Use a Bank Rating

  1. Name the rating. Record the agency or supervisor, scale, date, rated entity, and obligation.
  2. Read the methodology. Determine whether support, loss severity, seniority, or resolution assumptions affect the grade.
  3. Check the trend. Review recent upgrades, downgrades, outlooks, watches, and stated drivers.
  4. Use primary financial evidence. Compare capital, asset quality, liquidity, earnings, and concentration with the rating rationale.
  5. Separate public and confidential information. Do not claim or infer a CAMELS score from a public rating.
  6. Add market and supervisory context. Bond spreads, deposit flows, regulatory filings, and enforcement actions can provide different signals.

Common Mistakes and Limitations

  • Treating every bank rating as an issuer credit rating.
  • Assuming a holding-company rating applies to an operating bank or insured deposit.
  • Comparing letter grades without reading each agency’s scale.
  • Treating a rating as real-time; material conditions can change before the next action.
  • Assuming a high rating guarantees liquidity or repayment.
  • Inferring a confidential supervisory rating from public data.
  • Treating private consumer bank scores as official regulatory findings.
  • Ignoring conflicts, model limitations, qualitative judgment, and methodology changes.
