Assess a lender across the full life of its loans—not by one headline ratio. Examine who it lends to and on what terms, how it monitors repayment, whether risks are concentrated, and whether its expected-loss allowance is credible. Then compare those findings over time and with genuinely similar lenders, using consistent definitions.
Start by defining the lender and the evidence you need
Before interpreting a loan-quality figure, identify the legal entity, products, countries, reporting period, and accounting framework it covers. Establish whether the company is a bank, savings association, or nonbank lender. The rules and supervisory guidance for one category do not automatically apply to another.
The OCC’s Lending and Loan Portfolio Risk Management handbook, Version 1.0 (June 2026), is supervisory guidance for U.S. national banks and federal savings associations. European Banking Authority (EBA) guidelines address institutions within their EU scope; applicability to a particular company depends on its status and jurisdiction. Keep those boundaries in view rather than treating either framework as a universal rulebook.
Use company-level evidence where it is available: audited financial statements, regulatory returns, loan-level data, portfolio disclosures, and information about collateral. Supervisory frameworks help organize the questions, but cannot establish the condition of a specific lender without evidence about that lender.

Is credit risk governed and independently challenged?
Look for clear responsibility for credit decisions, documented risk appetite and limits, controlled exceptions to policy, and escalation when performance weakens. The board and senior management should receive information that makes portfolio performance and problem trends visible, rather than a single aggregate number with no context.
Check whether an independent credit review function can identify weaknesses in underwriting, risk grades, documentation, or problem-loan handling—and whether findings lead to action. The 2020 interagency guidance from the OCC, Federal Reserve, FDIC, and NCUA addresses credit-risk review systems and communication of portfolio performance to management and boards.
Are loans originated on sound terms?
Assess how the lender evaluates borrowers’ ability and willingness to repay, and whether approval decisions follow documented standards. Consider whether the lender records the basis for approval, applies its stated criteria consistently, and tracks exceptions. A high growth rate alone does not establish weak underwriting, but it makes it especially important to check whether standards, borrower mix, or approval practices changed as the book expanded.
The EBA’s final Guidelines on loan origination and monitoring cover governance, creditworthiness assessment, and monitoring across a credit facility’s lifecycle. Their stated application date is 30 June 2021. The EBA says the guidelines aim to support robust, prudent credit-risk taking and high-quality newly originated loans. They are not a guarantee that a particular institution or loan portfolio meets that standard.
Does monitoring catch deterioration early?
Follow what happens after origination. Find out how the lender tracks missed or late payments, risk-grade changes, restructurings, and—where relevant—covenant compliance and collateral values. Ask whether worsening accounts are escalated promptly and whether the company can explain how it handles them.
Segment the book using dimensions relevant to the products, rather than relying only on a company-wide average. Basel Committee guidance on expected credit losses describes data that may support assessment, including product type, geography, origination vintage, collateral, loan-to-value (LTV), past-due status, internal ratings, estimated probabilities of default, amortization schedules, down-payment requirements, market segment, and historical loss rates. Not every dimension applies to every loan. The Basel consolidated-guidelines page published on 1 January 2026 labels its text as a draft under consultation and says the chapter is based on December 2015 guidance; do not present that draft as a finalized new standard.
How do the main loan-book indicators fit together?
Read asset-quality measures as a group, alongside changes in portfolio mix and the lender’s definitions. The EBA’s 2021 guidance for compiling IMF Financial Soundness Indicators identifies the following measures as useful indicators—not standalone verdicts:
| Indicator | What it can help show | What to check before interpreting it |
|---|---|---|
| Nonperforming loans (NPLs) to gross loans | The share of gross loans classified as nonperforming under the reporting definition. | How NPLs and gross loans are defined; whether classifications or servicing practices changed; and how the ratio varies by product, vintage, sector, and geography. |
| Provisions to NPLs | How provisions compare with the reported stock of nonperforming loans. | What the numerator includes, how NPLs are classified, and whether collateral, expected recoveries, or portfolio composition affect the comparison. |
| Loan concentration by economic activity | How much exposure is tied to particular sectors, which can reveal dependence on a narrower set of economic conditions. | Sector definitions, the size and direction of exposures, and whether the lender’s other borrower or geographic concentrations compound the risk. |
For each measure, examine both its level and its direction over comparable reporting periods. Then ask whether the change reflects borrower deterioration, new lending, repayments, write-offs, a shift in portfolio mix, or a change in definitions. Compare lenders only when their products, geographies, reporting bases, and relevant portfolio segments are meaningfully similar. The cited supervisory sources do not establish a universal “good” threshold; do not invent one in the absence of a relevant regulatory requirement, contract, or defensible peer dataset.

A lender’s allowance for credit losses is an estimate, not a count of loans already lost. Assess the quality of the data and assumptions behind it, the documented estimation method, validation, internal controls, governance, and independent or examiner review. Look for whether the process responds to changes in portfolio risk and whether management can explain significant movements in the estimate.
Keep accounting frameworks distinct. The OCC’s U.S. materials discuss the allowance for credit losses and the Current Expected Credit Losses (CECL) approach. The OCC describes the allowance as a valuation account presenting the net amount expected to be collected over contractual terms. Its allowances page includes a revised April 2023 interagency policy statement and an OCC handbook booklet dated July 2026. For EU institutions applying IFRS 9, EBA’s separate guidelines on credit-risk management practices and accounting for expected credit losses are final and in force, with an application date of 1 January 2018. CECL and IFRS 9 are not interchangeable labels for a single method.
How to form a conclusion without overstating the evidence
Write down what is observed separately from what it may mean. A useful assessment identifies the lender’s stronger practices, adverse trends, material concentrations, uncertainties in loss recognition, and gaps in monitoring or governance. State where disclosures are insufficient to reach a firm conclusion instead of treating missing information as proof of either safety or distress.
When comparing periods or lenders, keep definitions consistent and compare like with like: product or asset class, borrower and sector mix, geography, origination vintage, collateral and LTV, delinquency and risk-grade migration, loss history, allowance coverage, and changes in growth or underwriting. A ratio that worsens as a lender enters a riskier segment may require a different interpretation from the same movement in an unchanged book.
