What it means
An examination is a supervisory exercise rather than an accounting one. The regulator's question is not merely whether the numbers are stated correctly but whether the bank will still be standing under stress, which means examiners spend most of their time on asset quality and risk controls.
Many supervisors organise their findings using a framework covering capital adequacy, asset quality, management, earnings, liquidity and sensitivity to market risk, widely known by the acronym CAMELS. Each component is scored, and the composite score drives how closely the bank is supervised afterwards.
The work is intrusive by design. Examiners sit on site, pull individual loan files, re-perform the bank's own grading of borrowers, test whether collateral valuations are current, and interview staff several levels below the executive team.
For a business banking with the institution, examinations matter indirectly but genuinely. A bank told to raise provisions or rebuild capital will tighten lending criteria, cut facility limits and slow down credit decisions, often without explaining why to customers.
The results are usually confidential, and a bank is normally prohibited from publishing its supervisory rating. What does surface publicly is enforcement action, such as a formal agreement or a direction to raise capital, which is why those announcements move share prices so sharply.
In practice
Real-world examples.
Example
Examiners at a community bank re-grade a sample of commercial property loans and downgrade several the bank had rated as performing. The bank must raise its loan loss provision, which reduces reported earnings for the quarter.
Example
A mid-sized bank is found to have weak controls over customer identification checks. The examination results in a formal agreement requiring an independent review and a hiring plan for the compliance team, and the bank's expansion into a new region is paused.
Example
A savings institution passes on capital and asset quality but is criticised for concentrating its funding in short-term wholesale deposits. It is directed to build a larger liquidity buffer, which lowers its interest margin but reduces its vulnerability to a funding squeeze.
Formula
Calculation
A central test in any examination is the capital ratio: common equity tier 1 ratio = common equity tier 1 capital / risk-weighted assets.
Suppose a bank holds $72,000,000 of common equity tier 1 capital against $800,000,000 of risk-weighted assets. The ratio is $72,000,000 / $800,000,000 = 9.0%. If the minimum plus the required buffer comes to 7.0%, the capital needed is $800,000,000 x 0.07 = $56,000,000, so the bank has a surplus of $72,000,000 - $56,000,000 = $16,000,000.
Examiners then test what happens if the balance sheet grows. If risk-weighted assets reach $1,000,000,000 with capital unchanged, the ratio falls to $72,000,000 / $1,000,000,000 = 7.2%, leaving almost no headroom and prompting a supervisory conversation about growth plans.Case study
Seen in the real world.
Cedarbank Mutual is an illustrative, entirely fictional regional bank used here to show how an examination plays out. It had grown its loan book to $640,000,000 over five years, and management was proud of a low arrears rate and a comfortable 10.4% common equity tier 1 ratio on $700,000,000 of risk-weighted assets, which equated to $72,800,000 of capital.
Examiners looked past the arrears figure and at concentration instead. They found that 18% of the loan book, some $115,200,000, was lent against one type of commercial property in a single metropolitan area, and that recent valuations were stale. After re-grading the worst files, the bank increased provisions by $5,500,000, cutting capital to $67,300,000 and the ratio to about 9.6%.
Cedarbank stayed comfortably above its minimum, but the finding changed its behaviour: it capped further lending to that sector, refreshed its valuation policy and diversified its book over the following two years. The lesson in this fictional case is that examinations are usually about concentration and control quality, not about catching arithmetic errors.
Watch out
Common mistakes.
- Assuming a bank examination is just an audit under another name, when its purpose is supervisory judgement about future safety rather than an opinion on past financial statements.
- Reading a clean set of published accounts as evidence that a bank has passed its examination, since supervisory findings are usually confidential.
- Believing arrears data alone shows loan book quality, when examiners focus at least as hard on concentration, collateral valuation and grading discipline.
Questions
People also ask.
How often are banks examined?
Larger and riskier institutions are supervised more or less continuously, while smaller banks typically face a full on-site examination every twelve to eighteen months.
Can I find out my bank's examination rating?
Generally no, because supervisory ratings are confidential, though public enforcement actions and capital ratios give useful indirect signals.
Should a business worry if its bank is under enforcement action?
It is worth paying attention, since such banks commonly tighten credit and cut limits, so having a second banking relationship becomes a sensible precaution.
