CAMELS is the rating system used by U.S. bank regulators — the OCC, FDIC, Federal Reserve, and state banking agencies — to evaluate the condition of banks and other supervised financial institutions. The acronym stands for Capital adequacy, Asset quality, Management, Earnings, Liquidity, and Sensitivity to market risk. Each component is rated on a 1–5 scale, with 1 representing the strongest performance and 5 representing the most critically deficient. A composite CAMELS rating is assigned based on an overall assessment of the institution.
Capital adequacy assesses whether a bank holds sufficient capital to support its risk profile. Regulators evaluate total capital ratios (CET1, Tier 1, total capital), the composition of capital, and capital planning processes. Asset quality evaluates the condition of the loan portfolio — classified loans, non-performing assets, delinquencies, and reserve adequacy. A high classified-asset-to-capital ratio is a critical warning sign.
Management quality assesses the competence, integrity, and risk management capabilities of senior management and the board. Examiners review strategic planning, internal controls, audit functions, compliance, and the bank's culture around risk-taking. Management is often the most subjective CAMELS component but weighs heavily in composite ratings.
Earnings quality evaluates the bank's profitability — not just the level of earnings but their sustainability, composition (net interest income vs. fee income), and risk-adjusted quality. Liquidity assesses the bank's ability to fund its obligations — meeting deposit outflows, funding loan commitments, and accessing contingency funding without undue cost or disruption. Sensitivity to market risk evaluates exposure to interest rate risk, foreign exchange risk, and other market factors that can affect earnings and capital.
Banks rated 1 or 2 are considered satisfactory and face minimal regulatory scrutiny. Banks rated 3 face increased examination frequency and may be subject to informal regulatory actions. Banks rated 4 or 5 face formal enforcement actions — memoranda of understanding, cease-and-desist orders, or formal agreements — and may face operational restrictions. A 5-rated institution is at high risk of failure.
