lev-os Analyzing Banking System Health
Structures banking system assessment with capital adequacy, asset quality, and systemic risk evaluation.
When To Use
- Evaluating a country's or region's banking sector stability for policy research or investment analysis
- Assessing systemic risk buildup across a group of financial institutions
- Benchmarking individual bank health metrics against sector-wide or peer-group standards
- Reviewing banking system resilience in the context of stress scenarios, macro shocks, or contagion risk
- Preparing financial stability reports or macroprudential policy briefs
Inputs To Gather
- Bank-level financial data: Balance sheets, income statements, and regulatory filings for institutions in scope (call reports, FR Y-9C, pillar 3 disclosures, or local equivalents) [VERIFY jurisdiction-specific filing requirements]
- Regulatory capital ratios: CET1, Tier 1, Total Capital ratios, leverage ratios, and supplementary leverage ratios where applicable
- Asset quality metrics: Non-performing loan (NPL) ratios, loan-loss provisions, charge-off rates, and coverage ratios
- Liquidity indicators: Liquidity Coverage Ratio (LCR), Net Stable Funding Ratio (NSFR), loan-to-deposit ratios
- Market and macro data: Sovereign spreads, interbank lending rates, credit default swap spreads on major banks, yield curve shape, GDP growth, unemployment, and inflation trends
- Supervisory and stress test results: Central bank or regulator-published stress test outcomes (e.g., Fed DFAST/CCAR, EBA stress tests) [VERIFY which stress test framework applies]
- Structural context: Number and concentration of institutions, deposit insurance framework, resolution regime, government ownership stakes
Workflow
Define scope and time horizon
- Specify the banking system (national, regional, or a peer group of institutions)
- Set the assessment date range and any forward-looking horizon
- Identify the regulatory framework governing the system (Basel III/IV implementation status, local capital rules) [VERIFY local regulatory standards]
Assess capital adequacy
- Calculate aggregate and distribution-based CET1, Tier 1, and Total Capital ratios across institutions
- Compare against minimum regulatory thresholds and buffers (capital conservation buffer, countercyclical buffer, G-SIB/D-SIB surcharges) [VERIFY applicable buffer levels]
- Identify institutions operating near minimum thresholds or showing deteriorating capital trends
- Evaluate quality of capital: proportion of CET1 vs. AT1 instruments, deferred tax asset reliance, goodwill/intangible deductions
Evaluate asset quality
- Aggregate NPL ratios by loan category (commercial, consumer, mortgage, CRE)
- Assess loan-loss reserve adequacy: coverage ratio (provisions / NPLs), trend in net charge-offs
- Identify sector or geographic concentrations in loan books that introduce correlated default risk
- Flag forbearance or restructured loan volumes that may mask true asset deterioration
Analyze liquidity and funding structure
- Review system-wide LCR and NSFR compliance
- Evaluate funding mix: reliance on wholesale funding vs. stable retail deposits
- Check for maturity mismatches and rollover risk in wholesale markets
- Monitor interbank market conditions — spreads, volumes, and counterparty credit concerns
Measure profitability and earnings resilience
- Calculate return on assets (ROA), return on equity (ROE), and net interest margin (NIM) across the system
- Assess cost-to-income ratios and operating efficiency trends
- Evaluate earnings capacity to absorb credit losses (pre-provision net revenue relative to projected losses)
Assess systemic risk indicators
- Compute concentration metrics: share of total assets held by top 3–5 institutions (Herfindahl-Hirschman Index)
- Map interbank exposures and counterparty networks to identify contagion channels
- Review CDS spreads and equity market signals for distress pricing
- Evaluate sovereign-bank nexus: bank holdings of domestic sovereign debt, government guarantees, and implicit backstop expectations
- Consider cross-border exposures and foreign-currency lending vulnerabilities
Stress-test sensitivity analysis
- Apply scenario-based shocks: interest rate shifts, GDP contraction, asset price declines, funding freezes
- Estimate capital depletion under adverse scenarios and identify institutions that breach minimum thresholds
- Assess second-round effects — fire-sale dynamics, credit contraction feedback loops
Synthesize findings and assign risk rating
- Summarize each pillar (capital, asset quality, liquidity, earnings, systemic risk) with a qualitative rating (strong / adequate / weak)
- Highlight the 2–3 most material vulnerabilities and their transmission mechanisms
- Provide an overall banking system health assessment with directional outlook (improving / stable / deteriorating)
Output
Produce a structured Banking System Health Assessment Report containing:
- Executive summary: Overall health rating, key vulnerabilities, and outlook in 3–5 sentences
- Capital adequacy section: Aggregate ratios, distribution, buffer analysis, and trend
- Asset quality section: NPL rates, coverage, concentration risks, forbearance flags
- Liquidity and funding section: LCR/NSFR compliance, funding mix, maturity profile
- Profitability section: ROA, ROE, NIM trends, loss-absorption capacity
- Systemic risk section: Concentration, interconnectedness, sovereign-bank nexus, contagion assessment
- Stress scenario results: Capital impact under adverse scenarios, institutions at risk
- Risk matrix: Summary table mapping each pillar to rating and key concern
- Recommendations: Policy or portfolio actions warranted by findings
- Limitations and data gaps: Disclose missing data, stale inputs, or analytical constraints
Quality Checks
- All capital ratios verified against source regulatory filings — not derived from secondary summaries
- NPL definitions used consistently (90-day past due vs. local regulatory definition) [VERIFY local NPL classification rules]
- Stress test assumptions are explicit, internally consistent, and disclosed
- Concentration analysis uses current-period data, not lagged proxies
- Sovereign-bank nexus assessment accounts for both direct holdings and indirect channels (guarantees, collateral eligibility)
- Forward-looking statements clearly distinguished from historical observations
- All [VERIFY] markers resolved or flagged for human review before finalization
- Cross-check aggregate figures against central bank financial stability reports or IMF FSAP assessments where available
