A non-banking financial company looks like a bank from the outside. It lends money and it earns interest. The difference is on the other side of the balance sheet: it cannot accept demand deposits, so it has to buy its money in the market at whatever price the market is charging that day. Almost everything distinctive about this sector — the growth, the margin, the periodic crisis — follows from that single restriction.
Insurance sits in the same index bucket and is a different machine again. An insurer collects money before it owes anything, invests the gap, and pays claims years later. That gives it two profit engines instead of one, and they have to be read separately. This article covers the non-bank financial businesses; banks have their own article and are used here only as the comparison.
Why a non-banking financial company is not a small bank
A bank has one privilege that decides almost everything about it: it can accept demand deposits — the current and savings accounts people keep money in for convenience rather than for return. That money is cheap, it is sticky, and the depositor is not really shopping for a rate. A non-banking financial company (NBFC) cannot do this. A few categories are permitted to accept fixed-term public deposits under strict conditions, but no NBFC runs a current-account or savings-account franchise.
So an NBFC buys its money. It borrows from banks, issues bonds and non-convertible debentures, sells short-tenor commercial paper, raises money abroad, and securitises loan pools — meaning it sells a slice of its existing loans to a bank or a fund for cash today. Every one of those has a market price and a maturity date attached to it.
What it gets in exchange for giving up cheap deposits is reach and speed. An NBFC lends where a bank's process will not go: a used-truck buyer with no formal income proof, a customer who wants money against gold jewellery by evening, a small trader in a district town. Housing finance companies, which are regulated by the Reserve Bank of India, sit inside the same structure with a much longer asset.
Note — Hold on to one idea for the rest of this article. The asset side of an NBFC is a variation on lending. The liability side is a different business altogether, and it is where the risk lives.
Cost of funds is the central variable
For a bank, the cost of money moves slowly. Savings-account rates barely move, and term deposits only reprice at renewal. For an NBFC, the cost of money is whatever the market charges it today.
That price has two parts. The first is the general level of interest rates, which the Reserve Bank of India influences through the policy repo rate and through how much surplus cash it leaves in the banking system. The second is the credit spread — the extra a borrower pays over a government bond because of who it is. A credit rating is literally the price tag on that spread. An upgrade is a permanent cut in funding cost. A downgrade is a permanent increase, and it arrives at the exact moment the company can least afford it.
This is why parentage matters so much in this sector. A lender owned by a large bank or a well-capitalised group borrows more cheaply than an identical standalone lender, because the market prices in who would step in. That is not a small edge. On a book earning a spread of a few percentage points, half a point of funding cost is a large share of the profit.
Borrowing short to lend long — the mismatch that defines the risk
A home loan runs for fifteen or twenty years. The money funding it might be a three-year bond, or ninety-day commercial paper. That gap is asset-liability mismatch, and it is not an accident or a management failure. It is how the business makes money, because short money is cheaper than long money.
The risk is not the mismatch itself. The risk is its size, and what happens on the day the short borrowing matures. The lender has to repay it out of a loan book that has not matured, which means it has to borrow again — refinance. Refinancing works right up until the market decides it does not want to lend to this borrower, or to this whole category, at any sensible price.
Every regulated lender publishes an asset-liability maturity table in its annual report: how much money comes in and how much goes out in each maturity bucket. Read the buckets under one year. A large negative gap in the near buckets, funded by an assumption that the market will always be open, is the most useful advance warning this sector gives you. Larger NBFCs are also required to hold a buffer of liquid assets for exactly this reason.
Watch out — A lender rarely fails because a loan went bad on a Tuesday. It fails because it could not refinance on a Tuesday. Solvency and liquidity are different problems, and liquidity is the one that kills quickly.
Why the sector has a squeeze every few years
The pattern repeats because the structure invites it. Funding is cheap and plentiful for a while. Lenders grow the book faster than they can underwrite it, and fund that growth with progressively shorter money, because short money is the cheapest money. Then one large borrower in the category defaults — the 2018 default of a major infrastructure financier is the episode most people remember — and the market stops distinguishing between good and bad names in that category.
What follows is mechanical. Mutual funds, which are large buyers of non-bank paper, face their own redemptions and stop rolling over commercial paper. Banks reprice. The weakest lenders cannot refinance, so they must shrink: they stop disbursing, sell loan pools to raise cash, and in the worst case default themselves. Even healthy lenders slow down, because growing a book while your funding cost is rising destroys the spread.
The recovery has a consistent shape too. Funding returns first to the strongest balance sheets, so share moves towards them. Treat this as a mechanism rather than a forecast: it tells you which questions to ask about a lender's liability side long before you look at its growth rate.
Spread, net interest margin, and the trade-off nobody escapes
Two numbers describe a lender's gross profitability. Spread is the yield on the loan book minus the cost of funds — the raw difference between what it charges and what it pays. Net interest margin, usually written NIM, is net interest income divided by average earning assets. NIM is normally the higher of the two, because part of the loan book is funded by the lender's own equity, which pays no interest.
Now the trade-off. A lender can raise its yield whenever it likes. It simply lends to borrowers other lenders declined, at a higher rate. Disbursements rise immediately, yield rises immediately, margin rises immediately, and reported profit looks excellent — because loans made this quarter are, by definition, not yet overdue.
The bill arrives roughly eighteen to twenty-four months later, when that vintage of loans reaches the age at which borrowers stop paying. This lag is the most important thing to understand about lender accounting. Fast growth at a rising yield is not evidence of a great business. It is a question about who the new borrowers are, and the answer only becomes visible after the growth has already been reported and applauded.
NIM = Net Interest Income / Average Earning Assets
Spread = Yield on Advances - Cost of Funds
Credit Cost = (Provisions + Write-offs) / Average Loan Book- Net interest income = interest earned on loans minus interest paid on borrowings
- Average earning assets = the average loan book plus interest-bearing investments
- Credit cost is normally quoted annualised, in percentage points of the loan book
Asset quality vocabulary, and the number that actually decides returns
Spread is the number the market talks about. Credit cost is the number that decides the return. A lender with a three-point spread and a credit cost of half a point keeps most of what it earns. A lender with a six-point spread and a four-point credit cost has done twice the work for a worse result, and carried far more risk to get there.
This is also why the segment matters so much. Every lending segment has its own normal credit cost, and the normal range differs by an order of magnitude between a gold loan and an unsecured personal loan. A number that is alarming in one segment is unremarkable in another.
- Stage 1
- Performing. Only the loss expected over the next twelve months has to be provided for.
- Stage 2
- Credit risk has risen materially since the loan was made — typically overdue, but not yet impaired. Lifetime expected loss must now be provided. This is the bucket that moves first.
- Stage 3
- Credit-impaired. Broadly the non-performing asset bucket, with lifetime loss provided and interest recognition restricted.
- Gross and net NPA
- Non-performing assets before and after subtracting the provisions already held against them.
- Provision coverage ratio
- The share of impaired loans already provided for. Higher coverage means less pain still to come through the profit and loss account.
- Credit cost
- Provisions plus write-offs for the period, over the average loan book. The annual price of having lent to the wrong people.
- Write-off
- Removing a loan from the books entirely. It reduces reported gross NPA without a rupee having been recovered.
Pro tip — Read gross NPA, Stage 2 and write-offs together. Gross NPA can fall in a quarter where asset quality actually got worse, simply because loans were written off. Stage 2 is the early-warning bucket and it moves before either of the other two.
The segments are separate businesses wearing one label
Calling all of this one sector is convenient and misleading. The funding structure is shared. The loss behaviour is not, and loss behaviour is what decides the outcome.
The pattern underneath the table is simple. Collateral that can be sold quickly — gold, a vehicle — produces small, fast, predictable losses. Collateral that cannot be sold quickly, or no collateral at all, produces losses that arrive late, in a bunch, and correlated with something happening outside the lender's control.
| Segment | Lent against | How losses behave | What to watch |
|---|---|---|---|
| Housing finance | The home, plus the borrower's salary | Slow, small, largely recoverable | Loan-to-value, balance transfers out |
| Loan against property | Self-occupied or business property | Larger, slow to cure, lumpy | End-use of the money, resale depth |
| Vehicle finance | The vehicle, which can be repossessed | Tracks freight rates and fuel cost | Used-vehicle prices, freight demand |
| Gold loans | Physical gold, short tenor | Very low — auction recovers it | Gold price, tenor, auction volumes |
| Microfinance | Nothing — group discipline only | Fine, then correlated and sudden | Collection efficiency, state by state |
| Unsecured consumer | Nothing — a credit score | Sours fast, written off fast | Sourcing channel, vintage curves |
| Small-business loans | Cash flow, sometimes property | Cyclical, moves with the economy | Cheque bounce rates, GST filings |
Why lenders are valued on price-to-book
For a manufacturer, book value is the depreciated cost of factories and machines, and it tells you very little. For a lender, the balance sheet is the business. The assets are financial claims carried at something close to a real value, and net worth is roughly what would be left for shareholders if the book were collected in. That is why price-to-book is the standard multiple here rather than price-to-earnings.
What justifies the multiple is return on equity. If a lender earns more on its equity than shareholders require for the risk, every rupee of book value is worth more than a rupee, and the stock trades above book. If it earns less, it trades below. Growth amplifies whichever of the two is true, in both directions.
Two cautions. Book value is only as honest as the provisioning behind it, so an under-provided book overstates net worth and a low price-to-book may be pricing a book value nobody believes rather than an opportunity. And lending growth consumes equity, because every rupee lent needs regulatory capital behind it. A fast-growing lender either raises capital, diluting existing shareholders, or runs its capital ratio down. Read capital adequacy and the growth rate together — they are one story told from two sides.
Insurance: the same index bucket, a completely different machine
An insurer is not a lender at all. It takes money before it owes anything. Premiums arrive today; claims are paid at some unknown point in the future. The pool of money held in between is the float, and it is invested.
That gives an insurer two separate profit engines. The underwriting result is premiums minus claims minus the cost of running the business — it measures whether the company priced and selected its risks correctly. Investment income is what the float earned — it measures markets and interest rates. They have to be read separately, because they are different skills and they fail at different times. An insurer can report a comfortable year on the strength of investment gains while its pricing quietly deteriorates, and none of that is visible in the headline profit line.
Life versus general insurance
Life insurance sells contracts that run for decades, often mixing protection with savings. General insurance — motor, health, fire, marine — mostly sells one-year contracts that are repriced at every renewal. That one difference in duration produces two entirely different measurement systems.
For a life insurer the cost of selling a policy is incurred immediately, while the profit emerges over the life of the contract. Reported statutory profit therefore understates a fast-growing life insurer and flatters one that has stopped growing. Embedded value exists to fix that distortion, and price-to-embedded-value is the multiple that follows from it.
For a general insurer the accounting is far more immediate, so the combined ratio does most of the work. Below 100% means the company made money on underwriting before counting a rupee of investment income. Above 100% means underwriting lost money and the float has to cover the gap. That is a legitimate business model, but it is a different one, and it depends on investment markets cooperating.
- Annualised premium equivalent (APE)
- Regular premium plus one-tenth of single premium. It lets you compare new business without one large lump-sum policy distorting the picture.
- Value of new business (VNB)
- The present value of the profit expected from policies sold during the period. VNB margin is that figure divided by APE.
- Persistency
- The share of policies still paying premium at the 13th, 25th, 49th and 61st month. Selling costs are front-loaded, so an early lapse can destroy the economics of a policy that looked profitable when it was sold.
- Embedded value
- Adjusted net worth plus the present value of profits from business already in force. It excludes future sales entirely, which is what makes it a measure of what already exists.
- Combined ratio
- Claims plus expenses plus commissions, divided by premium. Under 100% is an underwriting profit; over 100% is an underwriting loss.
- Loss ratio
- Claims as a share of premium — the pricing half of the combined ratio, separated from the cost-control half.
Bank, NBFC and insurer, side by side
Three businesses, three funding models, three risks, three multiples. Reading one with the other's yardstick is the most common analytical error in this part of the market.
| Business | How it funds itself | How it earns | Main risk | Usual multiple |
|---|---|---|---|---|
| Bank | Public deposits, including current and savings | Spread on lending, plus fees | Credit losses; loss of deposit franchise | Price-to-book |
| NBFC / housing finance | Borrowed money at market rates | Spread on lending, plus fees | Refinancing risk; credit cost | Price-to-book |
| Life insurer | Long-tenor policyholder premiums | Margin on new business, plus float returns | Lapses; interest-rate and market risk | Price-to-embedded-value |
| General insurer | Annual policyholder premiums | Underwriting result, plus float returns | Mispricing; large or catastrophe claims | Price-to-book or earnings |
How to actually track it
One closing limit. Everything above is sector mechanics, and sector mechanics set the weather, not the outcome. Underwriting quality is a company-level fact. Two lenders in the same segment, paying the same cost of funds, can produce completely different loss experience across a cycle, because one of them said no more often. Sector analysis tells you what to ask. It cannot tell you the answer for a particular balance sheet.
Every quarter, in this order
- Cost of funds quarter on quarter, and the mix of incremental borrowing. A rising share of short commercial paper funding long assets is the oldest warning in this sector.
- Stage 2 and Stage 3 balances in rupees, not only as ratios. A falling ratio on a fast-growing book can hide a rising rupee number.
- Credit cost annualised, compared with what is normal for that segment rather than with the market as a whole.
- Write-offs for the quarter, read next to the change in gross NPA.
- Disbursement growth alongside yield. Both rising quickly together is a question, not an achievement.
- Capital adequacy and gearing, against the growth the company says it is aiming for.
- Reserve Bank of India policy statements and system liquidity, plus where highly rated non-bank paper is trading relative to government bonds.
- Rating agency actions on the company and on its peers — the category tends to get repriced together.
- For insurers: monthly new business premium published by the industry councils and the regulator, persistency by cohort, and the combined ratio split into its loss and expense halves.
Key points
Spread = Yield on Advances - Cost of Funds. NIM = Net Interest Income / Average Earning Assets. Credit Cost = (Provisions + Write-offs) / Average Loan Book. Spread tells you the gross margin; credit cost tells you how much of it the lender actually keeps.
Example — Take two hypothetical lenders to see why spread alone is meaningless. Lender A yields 14% and pays 8%, a six-point spread. Lender B yields 18% and pays 9%, a nine-point spread, and reports much faster growth. Two years on, A's credit cost settles near one point and B's near five, because B bought its growth from borrowers A declined. B's larger spread has been more than eaten by losses, and B also carries the funding risk of a book that grew faster than its capital. The reported numbers looked best at exactly the point the risk was being created.
Pro tip — Before the profit and loss statement, open the borrowing-mix and asset-liability maturity tables in the annual report. The profit and loss account tells you what the last twelve months looked like. Those two tables tell you what the next twelve months can survive.
Warning — Gross NPA can improve while asset quality deteriorates, because writing a loan off removes it from the number. Never read gross NPA on its own — read it with write-offs, Stage 2 and provision coverage, and compare credit cost against what is normal for that specific lending segment.
Frequently asked questions
What is the difference between a bank and an NBFC?
A bank can accept demand deposits — current and savings accounts — which are cheap and stable, and it sits inside the payments system. A non-banking financial company cannot. It funds itself with bank borrowings, bonds, commercial paper and securitisation, all at market prices with fixed maturity dates. That makes an NBFC's cost of funds more volatile than a bank's and creates refinancing risk that a deposit-funded bank largely does not face. In exchange, NBFCs typically underwrite faster and reach borrowers a bank's process will not serve.
Why is cost of funds so important for an NBFC?
Because it is the largest cost in the business and the company does not control it. An NBFC earns a spread of a few percentage points between what it lends at and what it borrows at, so even half a point of extra funding cost is a large share of its profit. Funding cost moves with the general level of interest rates and with the company's own credit spread, which is why a rating downgrade is so damaging: it permanently raises the price of every rupee the company borrows from then on.
What is credit cost and how do I calculate it?
Credit cost is provisions plus write-offs for the period, divided by the average loan book, usually expressed annualised in percentage points. Provisions and write-offs come from the profit and loss statement and the notes to accounts; the average loan book is the average of the opening and closing assets under management for the period. It matters more than the reported margin because it tells you how much of the spread the lender actually keeps. Compare it against the normal range for that lending segment, not against the sector average.
Why are lenders valued on price-to-book instead of price-to-earnings?
Because for a lender the balance sheet is the business. Its assets are financial claims carried near a realisable value, so net worth is a meaningful measure of what shareholders own — unlike a manufacturer, where book value is just depreciated equipment. Price-to-book is then justified by return on equity: a lender earning more on its equity than shareholders require trades above book, and one earning less trades below. The multiple is only as reliable as the provisioning behind the book value.
What is the combined ratio in general insurance?
The combined ratio is claims plus expenses plus commissions, divided by premium. Below 100% means the insurer made a profit on underwriting alone, before any investment income. Above 100% means underwriting lost money and the returns earned on the float have to cover the shortfall. It splits into a loss ratio, which reflects pricing and claims experience, and an expense ratio, which reflects cost control — reading the two halves separately tells you which part of the business is driving the number.
What is embedded value and why do life insurers use it?
Embedded value is a life insurer's adjusted net worth plus the present value of future profits from policies already in force. It exists because life insurance accounting is badly mismatched in time: the cost of selling a policy is booked immediately while the profit emerges over decades, so reported profit understates a growing insurer and flatters a shrinking one. Embedded value measures what has already been sold, and value of new business measures what was added in the period. Price-to-embedded-value is the multiple that follows from it.
How do life and general insurance economics differ?
Life insurance sells long-duration contracts, so the profit is spread over decades and the key measures are value of new business, its margin, persistency and embedded value. General insurance sells mostly annual contracts that are repriced each renewal, so profitability is visible far sooner and the key measure is the combined ratio. Both earn investment income on the float, but a life insurer's float is far longer-dated, which makes interest rates a much bigger influence on its economics.
