Reading a bank's balance sheet, where deposits are the raw material

For a manufacturer, the balance sheet is a support act. The profit-and-loss account is where the business happens — goods sold, margins earned — and the balance sheet just shows the plant and working capital that made it possible. For a bank, that relationship is reversed. The balance sheet is the business. A bank takes in deposits and turns them into loans; its entire operation is the assembling and management of that balance sheet, and the profit is a thin margin skimmed off the top of a very large pile of other people's money. illustrative

So the lines read nothing like a manufacturer's. Deposits, which sit on the funding side and might look like borrowing, are the raw material — the cheaper and stickier they are, the better the business. Loans, called advances, are the earning asset, and their quality is almost the entire question. Net worth is a thin sliver, perhaps a tenth of the balance sheet, because a bank is deliberately levered around ten times — that is the design, not a warning. And there is a whole vocabulary that has no manufacturer equivalent at all: non-performing assets, provision coverage, capital adequacy, CASA — the share of deposits sitting in low- or no-interest current and savings accounts, a bank's cheapest funding. These are not exotic extras. They are the core of how you tell a sound bank from a fragile one.

This module reads that balance sheet the way it is meant to be read. Not "how much debt does it have" — that question is meaningless here — but four different ones: how cheap and stable is its funding, how good are its loans, how much of the losses has it already owned up to, and how much capital stands behind it if things go wrong. Get those four, and a bank's balance sheet stops being a foreign document and becomes the clearest statement of what kind of lender you are looking at.

The previous module established that a bank files under a different format and that its familiar lines have moved or vanished. This module does the balance sheet in full, because for a bank the balance sheet carries the risk the P&L only reports afterwards. A bank almost never fails on its profit-and-loss account. It fails on its balance sheet — on loans that stopped being repaid and losses it did not set aside for — and by the time that reaches the P&L, it is usually too late to matter. To judge a bank early, you read the balance sheet.

Four ideas do the work, and none has a real manufacturer equivalent. The CASA ratio measures how much of the deposits are cheap current-and-savings money rather than expensive term deposits — the quality of the raw material. The non-performing asset figure measures how much of the loan book has stopped performing — the quality of the product. The provision coverage ratio measures how much of those bad loans the bank has already set aside for — the honesty of the book. And capital adequacy measures how much capital stands behind the whole thing to absorb losses — the margin of safety, and the one number the regulator watches most closely.

Without this module, a reader either avoids banks entirely or, worse, reads them with a manufacturer's instincts and reaches confident nonsense: flagging the leverage as dangerous, missing that a low gross NPA can hide a badly under-provided book, or treating a bank that barely clears the capital floor as equivalent to one with a fat buffer. The point here is to replace those instincts with the four questions that actually read a bank's balance sheet, and to show what each looks like when it is honest and when it has been dressed up.

Look at the shape first, then read it.

Two columns, equal height, like any balance sheet. But every block means something particular.

The funding side — deposits are the raw material. The largest block by far is deposits. A manufacturer's instinct screams "that is a huge liability", but it is the opposite of a problem: deposits are the cheap money the bank lends out at a higher rate, and the whole business is the spread between the two. What matters is not the size of the deposits but their cost and stickiness. Current and savings accounts (CASA) pay little or no interest and tend to stay, so a high CASA share means cheap, stable funding. Bulk term deposits are expensive and flighty. A bank growing deposits by piling on costly term money is not growing its quality, only its size.

The asset side — advances are the product, and their quality is everything. The largest asset is advances, the loans the bank has made. Their quality is measured by how many have stopped being repaid: the non-performing assets. Gross NPA is the percentage of the book that has gone bad. But gross NPA alone is only half the story, because a bank chooses how much of that loss to set aside for. That is the provision coverage ratio — the share of bad loans already provided against. A bank with 3% gross NPA and 75% coverage has owned most of its problem; a bank with 3% gross NPA and 40% coverage is still hiding half of it in future profits. The honest number is the net NPA — the unprovided hole left after coverage.

Net worth and the buffer — capital adequacy. Net worth is deliberately thin, because leverage of around ten times is how a bank works. That thinness is why the regulator does not leave the buffer to the bank's discretion: capital adequacy is a regulated minimum, the ratio of the bank's capital to its risk-weighted assets — its loans and investments scaled up or down by how risky each one is. A bank barely above the floor has almost no room to absorb a bad year; one well above it can take losses and keep lending. The distance above the minimum, not merely clearing it, is the margin of safety.

Read those three blocks — cheap-and-sticky funding, well-provided loans, a fat capital buffer — and you have read the bank. The profit will follow from them; it rarely leads.

The bank balance sheet does not just add new lines — it inverts the meaning of the ones you already knew. Set it beside the businesses whose lines it borrows and reverses.

The inversion worth holding onto is that a bank reverses two of the most basic balance-sheet instincts at the same time. On the funding side, a very large liability (deposits) is good, not bad. On the asset side, something called loans is an asset the bank owns, not money it owes. A reader who keeps a manufacturer's reflexes — big liabilities are dangerous, loans are debt — will misread both sides of a bank's balance sheet in the same glance. The manufacturer cell is included precisely to mark the baseline: for a cement maker, borrowings really are a risk and high leverage really is a warning. The bank is not a harder version of that. It is the reverse of it.

Read the composite private bank's balance sheet as it stands in its fifth year. Total assets of ₹338,000 crore sit against net worth of ₹33,200 crore — about ten times levered, which is normal and healthy, not a red flag. Now run the four questions. illustrative

How good is the funding? Deposits of ₹282,000 crore fund most of the book, and 46% of them are CASA — cheap current-and-savings money that pays little interest and tends to stay. A high and rising CASA share is why this bank's cost of funds — the average rate it pays for the money it lends out — is low, which is the quiet foundation of its margin. If you saw CASA falling while deposits grew, you would know the growth was being bought with expensive term money, and the margin would be under pressure regardless of the headline.

How good are the loans? Advances of ₹230,000 crore are the earning asset. Gross NPA is 2.0% — two rupees in every hundred lent have gone bad — and, crucially, coverage is 78%, so more than three-quarters of that loss is already provided for. The net NPA, the unprovided hole, is just 0.5%. That is a well-owned book. Contrast the bank's own third year, when a credit-cycle stress pushed gross NPA to 3.2% and coverage down to 66%: same balance sheet, a worse and less honest asset picture, and the year the profit dipped as provisions rose.

How much buffer stands behind it? Capital adequacy is 17.1%, comfortably above the roughly 11.5% regulatory minimum. That gap is the margin of safety — room to absorb a bad year and keep lending rather than being forced to raise capital at the worst moment. A bank at 11.6% would report the same "meets requirement" and be in a completely different position.

The habit to build: for any bank, ignore debt-to-equity entirely and read four things off the balance sheet — the CASA share (is the funding cheap and sticky?), the gross NPA (how much has gone bad?), the provision coverage (how much of that is already owned?), and the capital adequacy against the floor (how much buffer stands behind it?). Those four, tracked over several years, tell you whether you are looking at a sound lender or a fragile one, long before the profit-and-loss account admits it.

The balance-sheet ratios tell you the state of the book today; they do not tell you what is about to walk into it. Gross NPA and coverage describe the loans that have already gone bad and been recognised. The loans that will go bad next year are still sitting in the "standard" book, indistinguishable on the face of the balance sheet from the good ones. A bank that has lent aggressively into a sector about to turn can show pristine NPA numbers right up until the slippage begins — good loans turning bad. The balance sheet is a snapshot of recognised trouble, not a forecast of coming trouble, and the difference is where credit cycles do their damage.

Nor can these ratios, on their own, catch a bank that is delaying recognition. NPA and provisioning depend on the bank actually classifying a loan as bad, and there are ways to postpone that — evergreening a struggling borrower with a fresh loan to keep the old one current, restructuring rather than recognising, lending to a related entity that repays just enough to stay standard. A book can look clean because the losses are real but unrecognised. Reading the disclosed numbers is necessary; noticing when they are suspiciously stable through a stressed cycle, and cross-checking against the restructured-book and slippage disclosures, is what catches the delay.

And the balance sheet does not tell you whether the loans are concentrated in a way that turns a single event into a solvency problem. Two banks with identical gross NPA can carry completely different risks if one has spread its book across thousands of small borrowers and the other has lent heavily to a handful of large groups or one cyclical sector. Concentration lives in the notes and the disclosures, not in the headline ratios, and a diversified 2% NPA book and a concentrated 2% NPA book are not the same bank.

How it comes up. When asset quality looks good, a sharp analyst probes whether it is genuinely good or merely unrecognised. The question sounds like this: "Gross NPA improved to 2% and coverage is 78%, but the restructured book grew and slippages ticked up in the SME segment. How much of the standard book is under stress, and what's your expected credit cost for next year?" The analyst is trying to see past the recognised numbers to the trouble not yet classified.

A good answer, verbatim-style.

"Right to push on that. Headline NPA is 2% with 78% coverage, but I'd point you to two things. The restructured book is 1.3% of advances, of which we expect roughly a third to slip, and we've already provided 30% against it. SME slippage rose to 2.6% annualised in the stressed quarter and we think it normalises to about 1.8%. Putting it together, we're guiding credit cost of 75 to 85 basis points next year, versus 75 this year. If the SME stress deepens, the swing factor is about 20 basis points. It's all in the asset-quality annexure."

Specific figures for the not-yet-bad book, a credit-cost guide with a stated swing factor, and where to read it. It lets you judge the coming trouble, not just the recognised trouble.

An evasive answer, verbatim-style.

"Asset quality remains robust and among the best in our peer group. Our underwriting standards are conservative and our provision coverage is very healthy. We don't see any material stress in the book and we remain comfortable with our credit-cost trajectory. The improvement in gross NPA reflects the strength of our franchise."

Reassuring and empty. It repeats the recognised numbers the analyst already has, gives no figure for the restructured book or the SME stress, and offers no credit-cost guidance with a range. "We don't see any material stress" is the exact claim a bank delaying recognition would also make, and it is unfalsifiable without the numbers the answer withholds.

The follow-up nobody asks. "What is the restructured book, the SGL and special-mention-account buckets, and the expected slippage from each?" That forces the standard book's hidden stress into daylight. Watch what happens when it is not asked. If "asset quality remains robust" is allowed to stand on the recognised numbers alone, an investor is trusting a snapshot of past trouble as if it were a forecast of future trouble. The silence is the tell — either the early-stress buckets are uncomfortable, or the analysts have stopped doing the asset-quality work that reads a bank properly.

The first trap is reading a bank with a manufacturer's balance-sheet instincts. Deposits look like a mountain of liabilities, so the bank looks dangerously indebted; loans sit on the asset side, which feels wrong; net worth is thin, which feels fragile. Every one of those reflexes is inverted for a bank. Deposits are the raw material, loans are the product, and thin net worth against a ten-times balance sheet is the design. A reader who does not consciously switch templates will conclude that every bank is a leveraged disaster, and be wrong every time.

The second trap is trusting a low gross NPA without reading the coverage behind it. A 2% gross NPA looks better than a 3% one, and often it is — but not if the 2% book has set aside only 40% against its bad loans while the 3% book has set aside 78%. The under-provided bank has a smaller recognised problem and a larger hidden one, because the unprovided losses are still sitting in future profits waiting to land. Gross NPA without coverage is half a number, and the half it leaves out is the half that hurts.

The third trap is treating "meets the capital requirement" as safety. Capital adequacy is a regulated floor, and clearing it is a minimum, not an achievement. A bank sitting at 11.6% against an 11.5% requirement has essentially no buffer: one bad year of losses can push it below the floor and force it to raise capital in a hurry, exactly when capital is most expensive and dilutive. A bank at 17% can absorb the same losses and keep lending. Two banks that both "pass" can be in entirely different positions, and reading the pass rather than the distance above the floor misses it.

So before you conclude a bank with a low gross NPA is the safer one, ask: what would change your mind? A provision coverage ratio far below its peers, a capital position sitting a whisker above the floor, or restructured loans parked just outside the NPA definition — any one of those flips "clean book" into "problem deferred." If you cannot state, in advance, the number that would move you from reassured to worried, you were trusting the headline, not reading the bank.
