A guide to the six supervisory components, their connections to bank business models, and what public evidence can and cannot show customers, partners and investors.

Version note: Added fee-business and counterparty perspectives, expanded the relevance to service continuity, and retained the distinction between public analysis, confidential ratings and the May 2026 proposal.

Capital above a regulatory minimum is not automatically available for distribution. Buffer rules, earnings-based payout limits, leverage constraints, subsidiary requirements and management’s stress capacity together determine how much a bank can safely return.

A portfolio can contain many separate borrowers and still depend on one economic outcome. Concentration analysis connects loans, guarantees, collateral and contingent commitments to the common shocks that can make losses arrive together.

The same bond can produce different reported equity effects under available-for-sale and held-to-maturity accounting. Its contractual payments and funding risks do not change with the label.

A deferred tax asset represents an accounting claim on future tax benefits. Its usefulness depends on legal availability, sufficient taxable income and timing; bank capital rules can restrict recognition beyond the financial-statement test.

Goodwill records the residual acquisition price after identifiable net assets are measured. A later impairment reduces reported profit and equity, but its relationship to cash, tangible equity and bank capital requires a separate bridge.

An upfront lending fee is not necessarily immediate accounting revenue. For loans held for investment, net deferred fees and qualifying direct costs generally enter interest income over the loan’s life, changing the effective yield.

A failed bank’s operating franchise can move to a buyer while losses and unresolved claims remain in a receivership. The bid process, least-cost standard and creditor hierarchy determine how continuity and loss allocation fit together.

Deposit insurance is funded through a risk-sensitive assessment system whose base differs from insured deposits. Ordinary premiums, the fund’s reserve ratio and crisis-related special assessments measure different obligations.

A stress test connects a hypothetical economic path to borrower losses, bank earnings and capital. Its result depends on scenario design, portfolio detail and accounting assumptions, and is neither a forecast nor a direct measure of cash liquidity.

How unused lines create a valuable customer option, a contingent funding need and a regulatory exposure that differs from expected draws.

Version note: Added working-capital and treasury perspectives, a commitment-pricing example and clearer separation of regulatory exposure, liquidity and customer value.

Net interest income and economic value describe different consequences of the same rate move. Connect both measures to deposit pricing, mortgage choices, securities portfolios and the cost of protecting future earnings.

Version note: Added product and customer implications, a costed funding-choice example and clearer distinctions among income, economic value, accounting equity and liquidity; retained the original rate sensitivities.
