Warehouse Lines: Funding Loans Before They Are Sold
A lender makes loans one at a time and sells them in pools. Between those two events the loans exist, they sit on the lender's own balance sheet, and something is paying for them. The sale has not happened yet, so the sale cannot be what is paying for them. A warehouse line is the funding that stands in that gap, and the gap is a timing problem before it is a funding arrangement.
Take the shape out of finance for a moment. A printing works buys paper in September for calendars that will be sold in December. From the day the paper arrives it is real, it is stacked in the godown, and it has already been paid for out of something. December has not happened, so the calendar money cannot have paid for the paper. Whatever pays for the paper was arranged before the buying started, and the day that arrangement disappears the works stops buying paper rather than stops printing. Every sentence below is that shape, in rupees, on a book of loans.

Suvarna Commercial Bank Limited, also invented, is a commercial bank and takes deposits, so a large part of its funding is already sitting with it before anybody asks a question about a pool. Rukmini Finance Limited has no deposits at all. Its funding therefore has to be arranged in advance, on terms, with a party that has to agree.
What is a warehouse line bridging?
Loans are originated continuously. One application is decided today, three more this week, a few hundred by the end of the month, and the lending goes out to each of them on the day it is approved. A pool of loans, by contrast, is sold in a single event on a single date, once it is large enough and uniform enough to be sold at all. Continuous originating and a single sale date are not in tension by accident. Together they are what makes the funding side of a lending business look the way it does.
Every loan made before the sale date is already an asset on the lender's balance sheet, and an asset on a balance sheet is funded by something whether or not anybody has decided what. Read that twice, because most confusion about this subject dissolves in it. The money has already gone out to the borrower. The money came from somewhere. If it did not come from a facility arranged in advance, it came from the lender's own money, and there is only so much of that.
The order of events on the funding side is therefore the reverse of what a reader usually pictures. The funding comes first and the lending it supports follows. A lender that has not arranged the funding cannot originate at all, however good the applications in front of it are and however keen a buyer for the finished pool might be.
Rukmini Finance Limited has made Rs 18,000 crore of loans and intends to sell them as one pool next quarter. What is paying for those loans today?
What does the lender pledge, and how much of the pool can it draw?
Rukmini Finance Limited assembles a pool of Rs 18,000 crore of loans it has made and pledges that pool to the party providing the line. Pledging is the whole security arrangement in one word: the loans stay on the lender's books, and the party providing the line has a claim over them if the arrangement goes wrong. Against that pledge the lender draws 80.0 per cent of the pool, or Rs 14,400 crore. The remaining Rs 3,600 crore of the pool is funded by the lender's own money.
The share drawn has a name, the advance rate, and here it is 80.0 per cent of the pledged pool. An advance rate is a negotiated term between two parties, not a rule and not a convention. The 80.0 per cent is a property of this one arrangement, agreed between two parties, and no advance rate anywhere else follows from it.
The advance rate on the pledged pool is 80.0 per cent. On a pool of Rs 18,000 crore, what is drawn and what is not?
Why does the split on the pool look like the split on the balance sheet?
Something is about to look like a rule, and it is not one. The pool is drawn 80.0 per cent against 20.0 per cent of the lender's own money. The whole balance sheet is funded the same way. Borrowings of Rs 14,400 crore and net worth of Rs 3,600 crore stand behind assets under management of Rs 18,000 crore, and that is 80.0 per cent against 20.0 per cent again. Two identical splits side by side, and a reader is entitled to ask what connects them.
Nothing connects them. The two shares agree because this one made-up arrangement was built at these figures, and an arrangement assembled at any other figures would show two different shares. A facility is not drawn at the proportion its lender happens to be funded at, no term in any facility looks at a lender's funding mix, and neither of these two numbers follows from the other in any direction.
The pool is drawn at 80.0 per cent and the whole balance sheet is funded 80.0 per cent by borrowings. Does one of those explain the other?
What makes this a line rather than an ordinary term borrowing?
Most readings of the funding side go wrong at one point in the loop. Follow the loop once, slowly. The lender draws against the pledged pool. The lender keeps originating. The new loans go into the pledged pool alongside the old ones. The pool is sold. The draw is repaid out of the sale proceeds. And then the lender draws again, against the next pool it has assembled. The facility is a limit that can be used, repaid and used again, not a sum borrowed once.
Think of the crates a milk vendor exchanges on his route every morning. The number of crates on the route never changes. The milk inside them is different every single day, and nobody would describe the crates as having been bought for one particular delivery. The loans inside the pool turn over week after week while the facility stays exactly where it is. A reader who pictures one loan funded by one borrowing has the wrong picture of a lending business entirely. A term borrowingMoney borrowed once for a stated period and repaid at the end of it, rather than a limit that can be drawn, repaid and drawn again as often as the arrangement allows. is that other picture, and the difference between the two is the difference between a limit and a lump.
What is the lender's own money underneath the draw actually doing?
The Rs 3,600 crore of the pool that the draw does not cover is not idle, it is not a reserve sitting in an account somewhere, and it is not a formality. The uncovered Rs 3,600 crore absorbs a shortfall in the pool before the party providing the line absorbs anything at all. Absorbing first is the entire reason the advance rate sits below 100.0 per cent of the pledged pool, and it is why the number is negotiated rather than assumed.
The shape of this is familiar from ordinary trade. A shopkeeper leaves a deposit with a distributor before a consignment is released, and whatever goes wrong with that consignment is set against the deposit first. Nobody thinks of the deposit as a payment. The deposit decides whose money is at stake first, and its size is haggled over rather than looked up.
There is a second thing that money is doing, and readers almost never see it. The money underneath is the lender's stake in loans the lender itself made and intends to sell. Having some of its own money underneath the pool keeps the lender interested in how that pool performs after it has stopped being the only party exposed to it. The point is different from safety and worth holding separately.
Rukmini Finance Limited is offered a facility twice the size of the one it has, on the same terms. How much more can it originate?
What actually limits how fast a lender can originate?
Worked forward from the per hundred rupees form, the answer is in plain sight. At an advance rate of 80.0 per cent, every Rs 100.00/- of pool needs Rs 20.00/- of the lender's own money underneath it. Rukmini Finance Limited has Rs 3,600 crore. Dividing the money it has by the money each hundred rupees of pool demands gives a pool of Rs 18,000 crore, exactly the pool it has.
The size of the facility is not the constraint. The lender's own money is, and a larger line against the same own money buys nothing at all. That reverses what almost every reader arrives with, so sit with it for a second. There is no Rs 20.00/- of own money left to put under the hundred-and-first rupee of pool, so a facility of any size whatsoever, offered on these terms, leaves the answer at Rs 18,000 crore.
One lever does move the answer, and only one. Raise the advance rate to 90.0 per cent and every Rs 100.00/- of pool needs only Rs 10.00/- of the lender's own money underneath it. Rs 10.00/- goes exactly twice as far as Rs 20.00/-, so the same Rs 3,600 crore then carries a pool of Rs 36,000 crore. A movement of ten points in a negotiated term has doubled the book, and ten points deserve more attention than the size of any facility anybody is offering.
Move the advance rate and watch the pool split one way while the carrying answer moves the other.
One control moves: the advance rate on the pledged pool, from 50.0 per cent to 90.0 per cent in steps of 5.0 points. The pledged pool stays at Rs 18,000 crore in the first panel and the lender's own money stays at Rs 3,600 crore in the second, and the cost of borrowings stays at 8.50 per cent a year throughout. Where the control opens is the arrangement worked in the text above, figure for figure: an advance rate of 80.0 per cent draws Rs 14,400 crore, needs Rs 3,600 crore of the lender's own money underneath it, and that same Rs 3,600 crore carries a pool of Rs 18,000 crore and no more.
Assumptions, on the control rather than in a footnote. Every figure on this control belongs to the one made-up arrangement worked above and to no market anywhere. The advance rate is a negotiated term between two commercial parties and not a convention. No market figure for one exists to check any setting against. What a different advance rate would cost is not on record, so the cost of borrowings is held at 8.50 per cent a year at every setting. Holding it there is an assumption rather than a finding. The pool is treated as one block of loans with no split by product, segment or vintage. One stated year sits behind these figures, and an advance rate agreed in one year tells nobody what the next negotiation will produce. And the arithmetic runs straight into conditions set by the Reserve Bank of India at rbi.org.in and the other authorities named below, so this is an arithmetic range and not a permitted one.
Three things are worth carrying away from that panel. The pledged pool never changes length, so raising the advance rate does not create a single extra rupee of loans, it only moves the boundary between whose money is funding them. The carrying answer in the second panel turns upward rather than rising in a straight line. The division is by the part the draw does not cover, and that part shrinks as the control moves right. And the reading worth stopping at sits inside the range. At 70.0 per cent the pool draws Rs 12,600 crore and needs Rs 5,400 crore underneath, and the same Rs 3,600 crore carries only Rs 12,000 crore. Between 70.0 per cent and 90.0 per cent the advance rate moves by twenty points and the carrying figure triples.
Move the advance rate from 80.0 per cent to 90.0 per cent. What happens to the pool that Rs 3,600 crore of the lender's own money can carry?
What does the line cost, and where does that cost land?
One rate is on record for what Rukmini Finance Limited pays for money, its cost of borrowings of 8.50 per cent a year. On borrowings of Rs 14,400 crore, that is Rs 1,224 crore for the year. The lending earned 14.50 per cent a year on assets under management of Rs 18,000 crore, or Rs 2,610 crore. Subtracting one from the other gives net interest income of Rs 1,386 crore. The cost of the drawn money does not sit in a line of its own anywhere. The drawn money lands inside the same funding cost the whole book carries, and the Rs 1,386 crore of net interest income therefore reads 7.70 per cent against assets under management of Rs 18,000 crore and no higher.
What does the money drawn under the facility cost Rukmini Finance Limited for the year, and where does that cost appear?
What happens to the line when the pool is sold?
Mechanically, the sale is the simplest moment in the whole arrangement. The pool goes, the proceeds arrive, the draw is repaid out of them, and the facility is free again for the next pool. Everything that made the facility a line rather than a lump happens in that one movement, and it is the reason the loop in the earlier figure closes rather than ending.
Arithmetically, though, the sale runs into six requirements, each named below and settled by an authority. Every one of those six is set by an authority, and every one of them moves. Each requirement below carries the authority that settles it and no value at all, because every one of those values is revised from time to time. The shape of a requirement outlives every value that could ever be written into it.
Between them the six rows below settle what may be done with a pool, what the lender that made the loans keeps hold of afterwards, what it holds against what it keeps, when the loans stop being its assets at all, how the pledge itself is recorded, and what may be offered to anybody buying the finished instrument. Not one value out of these six rows enters the arithmetic above. The arithmetic stands on the lender's own figures alone.
| The requirement | Who settles it, and where the current value is published |

If a second market ever had to be covered here, it would arrive as further rows beneath these, each carrying the body that sets it. No sentence in the mechanism above depends on a value from this table, so the mechanism would survive untouched.
What stops if the line is not renewed, and what does not?
A facility runs for a stated period. The loans it funds run for their own periods, and the two have nothing to do with each other. So the facility has to be renewed or replaced while the loans carry on regardless, and that is this lender's own vulnerability rather than anybody else's. A lender can be entirely current on every single loan it holds and still lose the funding that lets it make the next one.
The two consequences get blurred constantly, and the blur is where the misdescription starts. Separate them carefully. The funding for new lending has gone, so new originating stops. Nothing about the loans already made has changed, and nothing about them ever depended on the lender's funding arrangements, so they carry on being loans on the terms they were made on. A lender's funding problem and a loan already made are two different objects, and treating them as one is how this exposure gets described as something it is not.
What stands above is the shape of the exposure and not how often it bites. How often a facility goes unrenewed, and what a lender does in the weeks after, belongs to a credit cycle that one stated year of figures cannot show.
The facility is not renewed. Every loan in the pool is current. What stops?
How does somebody outside the lender actually read this arrangement?
Three readers use the same arithmetic and each of them wants a different sentence out of it. Somebody covering the lender from outside wants the ceiling: take the money the lender has of its own, divide it by what each hundred rupees of pool demands underneath it, and the answer is the largest book this lender can carry until something structural changes. On these figures that is Rs 3,600 crore over Rs 20.00/- per Rs 100.00/-, or Rs 18,000 crore.
The party providing the line reads exactly the same numbers from the other end. Its own question is how much of somebody else's money stands in front of its own money, and the answer here is Rs 3,600 crore in front of a draw of Rs 14,400 crore. Every negotiation about an advance rate is a negotiation about that one distance. The number is agreed between two parties rather than published anywhere.
And somebody putting money into the lender uses the pair as a growth question rather than a safety one. An announcement that a larger facility has been arranged says nothing about how much more lending is possible; an announcement that more of the lender's own money has arrived says everything. Think of a fruit seller with a handcart outside a station. The size of the wholesale market behind him is not what limits his day. The cart is. Give him a bigger market and he sells exactly what he sold yesterday; give him a bigger cart and the day changes.
Which side binds, and the mistake that gets it backwards
The mistake is made by a careful reader who has understood everything about the facility except which side of it binds. The reading runs as follows. Rukmini Finance Limited has drawn Rs 14,400 crore today, so a facility of twice that size ought to carry twice the loans, and growth becomes a matter of negotiating a larger one.
Here is what that costs, worked. A draw of Rs 28,800 crore at the same advance rate of 80.0 per cent belongs to a pool of Rs 36,000 crore. Rs 20.00/- has to sit under every Rs 100.00/- of pool, so a pool of Rs 36,000 crore needs Rs 7,200 crore of the lender's own money underneath it. The lender has Rs 3,600 crore. The reading is short by Rs 3,600 crore of the lender's own money, exactly the whole of what it already has, and no term negotiated with the party providing the line can produce it.
Worse than the size of the miss is where it sends the reader looking. The reading points a reader at the facility instead of at the lender's own money and the advance rate. The facility is not the constraint. The other two are. The fix is one question, and it holds as a rule. The question is not how large the line is. The question is how much of the lender's own money sits under every hundred rupees of pool, with the money it has divided by that.
One question settles how large a pool a lender can carry. Which is it?
The funding that stands between a loan being made and a pool being sold is built above, and each edge of it opens onto a subject of its own. How an instrument backed by a pool of loans is structured, priced, rated or sold to an investor is covered separately. Earnings on a loan book, and what survives of them to the lender's own money, are covered under loan book economics. The figures produced there are simply spent above. How a lending decision is made, and how a loan travels from application to disbursal, are covered under loan origination.
Whether a lender that takes deposits is a better business than one that does not is covered separately at the close of this sequence, and nothing above ranks the two. How credit risk is measured, priced or modelled is covered separately, and so is how any model is built, validated or governed. How a pool of loans behaves in a bad year sits outside one stated year of figures.
Six requirements are named above and not one carries a value: the conditions on which a pool may be securitised or transferred, the interest an originator retains in a pool it has sold, the capital held against that retained interest, when a financial asset may come off a balance sheet, the registration of a charge over the lender's own assets, and the conditions on which an instrument backed by a pool may be offered or listed. Nothing above tells any reader what to do about borrowing, about lending, or about money of their own.
Putting some of the lender's own money under a pledged pool is an arrangement between two parties rather than anybody's framework, and it carries no name. Four divisions rebuild the whole of this guide from scratch and each takes a moment on paper. Rs 14,400 crore over Rs 18,000 crore. Rs 3,600 crore over Rs 20.00/- per Rs 100.00/-. Rs 1,224 crore as 8.50 per cent of Rs 14,400 crore. And Rs 2,610 crore less Rs 1,224 crore, the one that lands in the accounts.
Which values are left open, and who holds them?
Each of the six rows names the authority that fixes it and the site where the live wording sits. The date shown against each row is the date the routing was confirmed and never the date of a value. Every one of those values is revised from time to time.
