Evaluating financial-services stocks — banks, NBFCs, and insurers — requires a different set of metrics than evaluating a manufacturing or consumer-goods company, because the “product” here is money itself, and the specific ratios that reveal quality (asset quality, margins, capital adequacy) don’t map directly onto the metrics used for other sectors.
Why financial-services companies need sector-specific analysis
A bank’s balance sheet looks fundamentally different from a typical company’s — deposits are liabilities, loans are assets, and the core business is managing the spread between what it pays depositors and what it earns from borrowers. Standard metrics like revenue growth or gross margin, useful for most other sectors, don’t capture what actually matters for a lender’s health, which is why the sector has its own dedicated vocabulary of ratios.
Key metrics for banks and NBFCs
- Net Interest Margin (NIM) — the spread between interest earned on loans and interest paid on deposits/borrowings, a core profitability measure for lenders.
- Gross and Net NPA ratio — the proportion of loans that are non-performing (not being repaid as scheduled), a direct measure of asset quality and credit risk.
- CASA ratio — the proportion of a bank’s deposits held in low-cost current and savings accounts versus more expensive term deposits, affecting its cost of funds.
- Capital Adequacy Ratio (CAR) — a regulatory measure of how much capital a bank holds relative to its risk-weighted assets, indicating its cushion against losses.
Key metrics specific to insurance companies
- Combined ratio — for general insurers, the ratio of claims and expenses to premiums earned; below 100% indicates underwriting profitability.
- Persistency ratio — for life insurers, the proportion of policyholders who continue renewing their policies, a proxy for product and service quality.
- Value of New Business (VNB) margin — a life insurance-specific profitability metric on newly written policies.
A worked example
Suppose two banks report similar headline profit growth for a quarter. Bank A’s growth came alongside a rising NPA ratio and a declining CASA ratio, meaning its cost of funds is rising and asset quality is deteriorating even as headline profit looks fine for now. Bank B’s growth came with a stable or improving NPA ratio and a steady CASA ratio. On headline profit alone, the two look comparable; on the sector-specific metrics, Bank B’s growth looks considerably more sustainable than Bank A’s, whose current profit may be masking building risk that could surface in future quarters.
Regulatory context that shapes the sector
Banks and NBFCs operate under RBI’s regulatory framework, including capital adequacy norms and provisioning requirements for bad loans, while insurers are regulated by IRDAI with their own solvency and disclosure requirements. Regulatory changes — a shift in provisioning norms, a change in priority-sector lending requirements — can materially affect sector economics in ways that don’t apply to most other industries, making regulatory awareness a bigger part of financial-services analysis than it typically is elsewhere.
How to build a research routine for this sector
- Compare NIM, NPA ratios, and CASA ratio (for banks/NBFCs) or combined ratio and persistency (for insurers) across a few quarters, not just the latest one.
- Check how a company’s metrics compare to sector peers of similar size, since absolute numbers mean less without a comparable benchmark.
- Stay aware of relevant RBI or IRDAI regulatory developments that could affect the whole sector, not just an individual company.
- Read past the headline profit number to the underlying asset-quality and margin trends driving it.
Common mistakes when evaluating this sector
- Comparing a bank’s or insurer’s metrics against companies from unrelated sectors using generic ratios that don’t capture what matters here.
- Focusing on headline profit growth without checking whether asset quality (NPA trends) is deteriorating underneath it.
- Ignoring regulatory developments that can affect the entire sector’s economics regardless of any individual company’s execution.
FAQ
Are NBFCs riskier than traditional banks?
NBFCs generally operate under a somewhat different regulatory framework than banks and can carry different funding and liquidity risk profiles, which is why comparing an NBFC’s specific metrics against other NBFCs, rather than directly against banks, gives a more meaningful picture.
Why does CASA ratio matter so much for bank profitability?
A higher CASA ratio means a bank is funding more of its lending through low-cost deposits rather than more expensive borrowed funds, generally supporting a healthier net interest margin.
Is a rising NPA ratio always a red flag?
A rising NPA ratio warrants closer attention, though it’s also worth checking whether it reflects a broader sector-wide credit cycle affecting most lenders, versus being specific to that one company’s underwriting standards.
Do AMCs (asset management companies) get analysed the same way as banks?
No — AMCs are evaluated on different metrics entirely, such as assets under management growth, expense ratios earned, and fund performance across schemes, since they don’t carry the loan-book and deposit structure that defines banking analysis.
How does credit rating agency coverage relate to evaluating a lender’s bonds versus its equity?
Credit ratings focus specifically on debt-repayment capacity and matter most for a lender’s bondholders, while equity investors need the broader profitability and growth picture on top of that, so a strong credit rating alone doesn’t tell the full equity investment story on its own.
Should dividend history matter when evaluating financial-services stocks?
A consistent dividend history can be a useful secondary signal of stable profitability, but it should be weighed alongside the sector-specific metrics above rather than treated as a standalone reason to invest, since a lender can maintain dividends for a period even while underlying asset quality is quietly deteriorating.
Provisioning and how it affects reported earnings
Banks and NBFCs are required to set aside provisions against loans expected to turn bad, and the size of these provisions in a given quarter can swing reported profit significantly even when the underlying lending business is performing consistently. A quarter with unusually low provisioning can flatter reported profit, while a quarter with a large one-time provisioning charge can understate the underlying earning power of the business. Checking the provisioning trend alongside headline profit, rather than treating profit as a clean, standalone number, is part of reading financial-services results properly.
How interest rate cycles affect the sector differently than others
Because lenders’ core business is the spread between borrowing and lending rates, broader interest rate cycles set by the RBI affect financial-services companies more directly and immediately than most other sectors. A rate-cutting cycle can compress margins for some lenders while boosting loan demand; a rate-hiking cycle can widen margins on new loans while potentially increasing stress on existing variable-rate borrowers. Understanding where the broader rate cycle currently sits adds useful context that’s less relevant when analysing companies in other sectors.
