How to Analyse Bank Stocks in India
To analyse bank stocks in India, treat the bank as a leveraged balance sheet whose earnings depend on funding quality, underwriting, pricing and capital. Start with deposits and loan mix, then study net interest income, fee income, operating cost, asset quality, provisions, liquidity and capital. A bank can report strong profit while risk is accumulating in new loan vintages, concentrated deposits or under-provisioned exposures.
A Bank's Business Model Begins with Funding
| Model | Main Earnings Driver | Core KPI | Main Risk |
|---|---|---|---|
| Universal retail bank | Spread on diversified loans plus fees | Deposit franchise, NIM, retail credit cost and cross-sell | Unsecured lending, deposit competition and operating leverage |
| Corporate-focused bank | Large-ticket lending, transaction banking and treasury | Corporate slippages, concentration, fees and capital usage | Single-name stress and cyclicality |
| Public sector bank | Large branch network, government-linked flows and broad credit | Deposit cost, recovery, productivity, capital and RoA | Legacy assets, capital allocation and policy influence |
| Small finance bank | High-yield retail or microcredit funded by deposits | Funding transition, credit cost, borrower concentration and capital | Geographic stress and liability volatility |
| Transaction-led bank | Current accounts, payments, cash management and fee income | Low-cost deposits, fee depth and customer retention | Technology, competition and concentration |
Two banks with similar loan growth can have very different risk because their funding, borrower mix, pricing and capital requirements differ.
Do Not Read Net NPA in Isolation
Net NPA can fall because recoveries improve, loans are written off, provisions rise or risky assets move outside the reported NPA pool. Review gross NPA, slippages, restructuring, overdue buckets, write-offs, recoveries, security receipts, standard-asset provisions and sector concentration together.
Rule: asset quality is a flow problem before it becomes a stock problem.
1. Analyse Deposit Quality Before Loan Growth
Deposits determine funding cost, liquidity and confidence. Split current accounts, savings accounts, retail term deposits, bulk deposits and certificates of deposit. CASA is useful, but average CASA, pricing, customer concentration and stability matter more than a quarter-end ratio.
Review deposit growth relative to loan growth. When loans grow faster than stable deposits, the bank may use costlier wholesale funding or raise deposit rates, compressing future margins. Examine the share of deposits above insurance limits, digital versus branch sourcing, maturity profile and dependence on a few institutional customers.
2. Break Loan Growth into Product, Borrower and Vintage
Separate mortgages, vehicle loans, credit cards, personal loans, microfinance, SME, commercial real estate, infrastructure and large corporate exposures. Growth in secured retail loans has different loss behaviour from unsecured consumer credit. Corporate growth can be attractive when pricing and covenants compensate for concentration.
Secured versus Unsecured
Track the share, ticket size, borrower income, bureau profile and loss history of each product.
Seasoning of New Loans
Recent growth may not yet show full delinquency. Compare cohorts after similar months on book.
Sector and Borrower Exposure
Measure large exposures, top groups, geography and correlated collateral.
Risk-Adjusted Yield
High yield is valuable only after expected loss, operating expense and capital consumption.
3. Understand Net Interest Margin Properly
Net interest margin reflects asset yield, funding cost and balance-sheet mix. It can expand temporarily when loan repricing is faster than deposit repricing and later reverse. Compare reported NIM with loan yield, deposit cost, excess liquidity and interest reversals.
Ask whether margin is supported by durable low-cost deposits, a higher-risk loan mix or a temporary rate cycle. A bank should not receive a quality premium for margin created mainly by unsecured credit without adequate credit-cost allowance.
4. Reconcile Asset-Quality Flows
Build a quarterly bridge: opening gross NPA, additions or slippages, upgrades, recoveries, write-offs and closing gross NPA. Compare slippage ratio with credit cost. Low credit cost during rising slippages may indicate provision release or delayed recognition.
Study special-mention accounts, restructured loans and overdue trends where disclosed. For retail portfolios, collection efficiency and early delinquency are leading indicators. For corporate portfolios, watch rating migration, covenant breaches and sector stress.
5. Evaluate Provisioning and Hidden Loss Absorption
Provision coverage should be assessed by asset type and collateral reality. A secured loan can still create loss when collateral is overvalued, legally difficult to enforce or correlated with the borrower. Review technical write-offs, contingent provisions, floating provisions and utilisation of management overlays.
Normalised credit cost should reflect a full cycle, not only the latest benign year. Compare expected loss with pricing and capital.
6. Inspect Fee Income and Treasury Profit
Separate recurring fees from distribution income, interchange, loan processing, transaction banking, recoveries and one-off gains. Treasury profit can be volatile and rate-sensitive. Core operating profit should be tested before trading gains and exceptional recoveries.
Fee growth is higher quality when it comes from durable customer activity rather than aggressive product sales or accounting reclassification.
7. Measure Operating Efficiency and Technology Productivity
Cost-to-income is useful, but investment cycles matter. A bank may spend heavily on branches, technology, compliance or collections before revenue scales. Track business per employee, deposits per branch, digital transaction share, customer acquisition cost and service quality.
Falling cost-to-income accompanied by weak controls, outages or collection capacity is not sustainable efficiency. Technology should improve customer retention, underwriting and operating resilience.
8. Assess Capital Adequacy and Growth Capacity
Review common equity tier 1, total capital, risk-weighted asset growth and buffers above regulatory minimums. Fast growth consumes capital even when accounting profit is strong. Adjust capital for unrecognised losses, subsidiaries, deferred tax assets and likely credit costs.
Estimate how much growth can be funded internally from retained earnings. Frequent equity issuance can support growth but dilute existing shareholders when returns are below the cost of equity.
9. Review Liquidity, Asset-Liability Mismatch and Concentration
Study liquidity coverage, investment book, wholesale funding, deposit maturity and asset duration. Long-duration fixed-rate loans funded by short deposits can create margin and liquidity risk. Also review exposure to one depositor segment, geography, industry or borrower ecosystem.
Liquidity is most valuable before stress, so do not judge it only after management has already raised expensive funding.
10. Value Sustainable Return on Equity
Price-to-book should be linked to sustainable return on equity, growth and risk. Start with normalised return on assets, multiply by sensible leverage and deduct the capital needed for growth. Adjust book value for under-provisioned assets, subsidiaries and non-core holdings.
A bank deserves a premium when it combines a durable deposit franchise, disciplined underwriting, transparent recognition, strong capital and repeatable fee income. A discount is justified for concentration, governance uncertainty, unstable funding or earnings dependent on recoveries and treasury gains.
