Netting and Settlement: Working It Out and Ending It

Netting is arithmetic: it sets obligations running in both directions against each other and leaves one figure. Settlement is an event: money or the thing itself moves, and the obligation is over. So a netted obligation has been measured, not met. Until something actually reaches an account, the whole of it is still owed and everything standing behind it is still standing.

Two different questions get asked about the same promise, and they get asked in a fixed order. How much is it, once everything pointing the other way has been counted. And has it actually been met. A statement answers both, one line under the other, on the same day. Two answers printed that close together are why almost every reader runs the two words together. The gap between those two answers is where an obligation in this machinery spends most of its short life.

Everything worked below runs on one invented reference asset. Its spot pricethe amount handed over to take the thing this minute, rather than on some agreed later date is Rs 2,000.00/-. Rs 2,000.00/- is also the exposure a single unit carries. Financing runs at 6.50 per cent a year, so a price agreed today for delivery a year out works out at Rs 2,130.00/-. Holding the thing produces no receipt of any kind along the way. Not one paisa reaches whoever is holding it between the day it is bought and the day it is sold. The absence of any mid-year receipt matters rather than being a detail: were the thing to throw something off halfway through, the carry arithmetic sitting behind Rs 2,130.00/- would land somewhere else entirely.

What do the two words actually do, before either of them is defined?

The verbs settle the confusion in about four seconds and the nouns take far longer, so the verbs matter more than the nouns. Netting works out. Settlement ends. One of them is arithmetic and the other is an event, and no amount of arithmetic performed anywhere by anybody has ever discharged an obligation.

Try it first on something with no finance in it whatever. The shape turns out to be identical. A household buys from the same shop all month, on account. Some months they return things. Sometimes the shop owes them credit for a short delivery. At the end of the month the two sides sit down and work out, carefully and honestly, exactly what is owed once the returns and the credits have been counted against the purchases. The two sides agree a figure and shake hands on it. And at that instant, precisely nothing has been paid. Nobody has handed over a note, nobody has tapped a phone against anything, and if the household walked out of the shop at that moment the shop would be exactly as short as it was before the conversation began.

The conversation was worth having. Turning a messy set of entries into one clean number is genuinely useful and genuinely hard. But the shop cannot pay its supplier with the number. The shop needs the money, and the money is a separate event that has not happened yet. In the machinery that stands behind traded contracts, the same two things happen every day, in the same order, and they are called netting and settlement.

The difference between netting and settlement is categorical rather than a matter of degree: neither is a larger or smaller version of the other, and putting them on one scale is precisely the confusion worth removing. The arithmetic itself, and how the netted figure behaves as obligations are added to a book, is worked as a moving picture under netting.

What is netting, taken entirely on its own?

Inside a defined set, netting sets obligations running in both directions against each other, and one figure is left where many stood. That is the whole of it. Netting is cancelling, and its output is a number.

Work it on a book of obligations. On one day, a position holder finishes with four obligations against the same middle. The first is Rs 80.00/- payable, being a 4.0 per cent move on the Rs 2,000.00/- of exposure one unit stands on. The second is Rs 40.00/- receivable, a 2.0 per cent move on the same exposure. The third is Rs 20.00/- receivable, a 1.0 per cent move. The fourth is Rs 10.00/- payable, a 0.5 per cent move. Every one of them is a NET arising from a mark.

Add the payable rows and Rs 90.00/- is what this position holder must hand over. Add the receivable rows and Rs 60.00/- is what should come back. Every row travelling on its own would put Rs 150.00/- of GROSS movement on the road. Rs 150.00/- is 7.5 per cent of the Rs 2,000.00/- of exposure. Set the two directions against each other and Rs 30.00/- is what remains payable, being 20.0 per cent of that gross and 1.5 per cent of the exposure. Four movements have become one, and 80.0 per cent of the travelling has been cancelled rather than performed.

Two things about that figure are worth holding on to before anything else happens. The Rs 30.00/- is a NET, not a PRICE and not a PAYMENT. And which obligations are permitted to be set against which, between which parties, and inside which defined set, is not a matter of arithmetic at all. The Securities and Exchange Board of India (SEBI) settles that, at sebi.gov.in. The cancelling above works only because the set is assumed to hold; whether it holds in any real arrangement is a question about wording and about rules, and it gets its own treatment further down.

What is settlement, taken entirely on its own?

Settlement is the movement that discharges the obligation: a payment leaves one account and reaches another, or the thing itself changes hands. Settlement is the only thing in this machinery that ends anything. Everything else measures, records, agrees, confirms or reports. Until settlement happens, a promise is still a promise, however carefully it has been written down and however many people have signed off on the figure.

Settlement requires strikingly little. By the time it happens the agreeing is finished, so it needs nobody to agree with it. Settlement does not need to be a large amount either. The Rs 30.00/- discharges an obligation just as completely as a much larger movement would. And it does not need to be interesting. The arithmetic is where the ideas are, so almost all of the writing about this machinery goes to the arithmetic. Settlement usually just happens, and it gets a sentence at the end. The imbalance in the writing is the direct cause of the error worth preventing.

When settlement happens, how long money takes to travel, and how long the thing itself takes to travel are all fixed by SEBI, at sebi.gov.in. No two contracts carry the same answer, the answer changes from one day to the next, and it gets revised on top of that.

Why does one of them always come before the other?

The dependency runs one way only, and once that is seen the ordering stops being arbitrary. Netting needs nothing whatever from settlement. Settlement cannot happen until netting has produced a figure. The arithmetic goes first every time. An amount that has not been decided cannot be moved. An amount that never moves can perfectly well be decided.

Which brings the trap into view. Because netting comes first, and because it produces a single satisfying number after real work, it feels like the conclusion of the day. Netting is the setup for the day. The number is the input to the part that has not happened yet, and a reader who treats the input as the output has quietly declared the day over while the day is still running.

For anybody who has to actually find the money, the consequence is sharper still. Knowing a figure and having the figure are two different states, and this machinery treats them completely differently. In the first state there is information. In the second state an obligation has been discharged. A treasury that has done the first and not the second has done arithmetic, and a treasury that thinks it has finished is a treasury that has not begun.

How is a price told apart from a payment and from a net?

A statement puts all three within a few centimetres of each other, and mixing them is the commonest error in this machinery. One test sorts them in a single pass, and size plays no part in it.

Asking where a figure lives has already labelled it. Rs 2,000.00/- spot and Rs 2,130.00/- agreed live on a screen and on a contract notethe document a participant receives recording what was done for them and on what terms, and nobody's balance stirs because they exist: those are PRICES. Rs 80.00/- leaving an account and Rs 40.00/- arriving in one move a balance at the instant they happen: those are PAYMENTS. Rs 30.00/- lives on a worksheet, reached by cancelling obligations that point opposite ways, and it leaves every balance exactly where it was until somebody acts on it: that is a NET. Three homes and three behaviours, and the error worth guarding against is reading one home's figure as though it behaved like another's.

Quantities sort the same way, with a different test. Rs 2,000.00/- multiplied by the units held gives what the position stands on and what margin is struck against, which is EXPOSURE. A swap's face amount with a rate applied to it behaves differently: the face amount itself stays precisely where it was while only the rate difference travels, which is what makes it a NOTIONAL.

What is still true once the netting is done?

At the instant the netting finishes, three things are exactly as they were.

The obligation still exists. The position holder still owes Rs 30.00/-, and owes it in full. Netting changed how many rows it takes to write the obligation down, from four to one, and a change in the number of rows is not a change in what is owed.

The collateral is still standing against it. Rs 160.00/- was put up against Rs 2,000.00/- of exposure, being 8.0 per cent of it. Rs 2,000.00/- of exposure resting on Rs 160.00/- posted is 12.50 times, and an adverse move of 4.0 per cent, worth Rs 80.00/-, swallows 50.0 per cent of the lodged amount. Leverage alone makes the position sound enormous and the margin figure alone makes it sound modest, so both limbs have to be read at once. Set the day's net of Rs 30.00/- beside the Rs 160.00/- lodged and it accounts for 18.75 per cent. Send every row on a separate trip instead and the Rs 150.00/- of gross would have swallowed 93.75 per cent. None of that collateral has been released, reduced or repurposed by the arithmetic.

And the counterpartywhoever sits on the other side of a contract, and therefore whoever is short if the other side does not pay is still exposed. Somebody is expecting Rs 30.00/- that has not turned up. Their day is not finished either, and no arithmetic performed on this side of the arrangement has improved their position by a single rupee.

Netting measured the promise; it did not collect it.

What becomes true only when something arrives?

Now the answer, and it is short because there is only one moment involved. One payment of Rs 30.00/- moves. The one payment is the whole event.

Three things change as it lands, and none of them changed a moment earlier. The obligation is extinguished. Extinguished means gone rather than merely measured. The exposure between those two parties, for that day, is over. And the collateral question changes shape rather than disappearing. The position is still open and tomorrow will produce a mark of its own, so the Rs 160.00/- that was standing against an unmet obligation now stands against the next day's.

Arrival is the only moment in the whole arrangement where anything at all is finished. And the machinery is built around that fact. The machinery does not wait until the end of the contract's life and then settle everything in one go. It reaches the moment of arrival quickly and repeatedly, day after day, precisely so that the amount outstanding at any instant stays small. The Rs 30.00/- above is a day's worth of obligation, not a year's. An arrangement that let obligations pile up unsettled would be an arrangement where the figure to be found on the bad day is enormous.

Are the two failures the same kind of failure?

Both words can go wrong, and telling their failures apart is what makes a reader useful in a room where something has gone wrong. Netting fails as a rule, and settlement fails as an event, and the two are answered by completely different parts of the machinery.

Netting fails when the set-off does not hold on the day somebody leans on it. The arithmetic was done correctly; the permission to do it turned out not to extend as far as everyone assumed. On the invented book above, what looked like Rs 30.00/- was really Rs 90.00/- payable, with Rs 60.00/- waiting separately on the other side of the arrangement rather than cancelling against it. The figure to be found triples, and it triples at the worst possible moment. The moment somebody tests a set-off is rarely a calm one. Whether a set-off holds is a question about wording and about rules. Above the wording sits SEBI, at sebi.gov.in, deciding which obligations may be set against which and between whom.

Settlement fails when the figure was right, everybody agreed it, and the money did not arrive. Nothing was miscalculated. Nobody misread a clause. There is simply an account that should have received Rs 30.00/- and did not. The whole collateral machinery is built backwards from that second failure, and the Rs 160.00/- was collected before anything went wrong rather than after.

Notice when the call goes out. Not after the position has gone wrong, and not once somebody has failed to pay. The position is open, the day's mark has just been struck, nothing whatever has broken, and that is exactly the moment collateral gets asked for. An arrangement that waited for trouble would be asking somebody already in trouble for money. Money is hardest to find at exactly that moment.

The steps that follow a movement that does not arrive were settled in advance, in a written order, long before anybody knew who would be on which side of it. The order is fixed ahead of the event on purpose. SEBI decides its steps and every figure inside it, at sebi.gov.in.

Why do both words sit on the same statement?

Because they are three stages of one day rather than three separate subjects. A statement shows the obligations that arose, then the figure they net to, then the movement, one under another, in the order they happened. Printed that way they look like a single continuous process, and the reason so many readers merge them is that the layout actively encourages it.

Only one of the three lines answers whether anything is finished, so read down the column and ask of each line whether it is arithmetic or an event. The obligations line is a record of measurement. The netted line is a record of measurement. The movement line is the only one that reports something happening in the world, and it is usually the shortest line on the statement.

Nothing in the arithmetic fixes when the movement happens, how long it takes to get where it is going, or how much time anybody has. A settlement cycle written from recollection looks authoritative, and looking authoritative makes it worse than no cycle at all. SEBI fixes what interval a payment may take before it has to be in the account, at sebi.gov.in. The line on a statement will carry a real date.

What does somebody actually do differently once they can tell the two apart?

The same netted figure lands in several places on the same afternoon, and each place does something different with it. Sorting the places by the action each one takes is more useful than sorting them by job title.

Somebody has to fund it. A desk responsible for cash reads the Rs 30.00/- as a requirement rather than as a result. The funding desk asks where the figure will come from and whether it is available in the right place, not what the figure is. To that desk, the netting stage is a heads-up and the settlement stage is the deadline. The desk will happily read a statement with the netted line missing, and cannot work at all with the movement line missing.

Somebody has to watch what is still outstanding. A desk responsible for risk reads the same figure and asks a different question: how much is standing unmet right now, across everything, and how much collateral is behind it. To that desk, the interesting number is what has not settled. A reader who conflates the two words believes that number to be zero. On the invented book above, that reader would report nil outstanding at the moment the netting completed, when the honest figure was Rs 30.00/-.

Somebody has to count it as finished. Whoever is producing a record of the day needs a rule for when an obligation stops being an obligation, and the only defensible rule is arrival. Counting a netted figure as discharged makes the day close early and makes tomorrow open with an item nobody is looking for.

The household version is exactly the same shape and worth keeping beside the finance version. Suppose a small caterer works four weddings in a month for the same hall, and the hall owes them for three of the four while they owe the hall for the venue on the fourth. At the end of the month everybody sits down and agrees a single figure. The caterer who treats that agreed figure as money will pay their vegetable supplier on the strength of it and discover, a week later, that the hall has not transferred anything. Nothing was miscalculated. The number was right. The caterer confused a worksheet with a bank account. A treasury desk makes the same error, at a different number of zeroes.

Which of the two actually ends the exposure?

Settlement does, and netting never has. That is worth stating without qualification, because every hedge weakens it. Fewer figures on a statement is not less exposure. A cleaner number is not a smaller obligation. Until something arrives somewhere, each side is exposed for the whole of the netted amount and the other side is exposed for the same.

Rs 2,000.00/- of exposure standing on Rs 160.00/- of posted collateral raises an honest next question: whether anybody should be standing where the position holder is standing. Every input to that question belongs to whoever holds the position. Whether the position is doing a job or is merely present. Whether something already held would be offset by it. The amount put up, and the amount that could be found at short notice if more were called for. The sum reaching the account on the single worst day rather than on an ordinary one. Weighing any of that needs a history of how positions like it actually turned out. Working out how an obligation gets discharged says nothing whatever about whether anybody belongs on either end of one.

Four things would have to be established before the question became answerable at all. The set the netting was struck over, and who agreed to it. Whether that set-off holds on the day it is tested, a question for the wording and for the rulebookthe written body of rules a market runs on, kept by an authority rather than by any participant in it above the wording. When movements are due, a matter SEBI fixes. And what follows when one of them does not arrive, fixed in advance and kept by SEBI.

One structural point explains why a middle exists at all. In a bilateralwritten directly between two sides with nobody standing in the middle of them, which is the opposite of a cleared arrangement arrangement, each side settles against the other and each side carries the other. In a cleared one, a clearing corporation stands between them, and a clearing membera firm admitted to deal with the middle directly, through which everybody else routes what they owe and what is owed to them faces that middle on the participant's behalf. The middle changes who is exposed to whom, and changes nothing at all about the two verbs: on either side of that arrangement, the arithmetic still measures and the movement still ends. Questions about the middle itself, meaning where its money comes from, what sits in reserve behind it and who answers for the way it is run, are covered separately. Principles for cleared markets that cross borders originate with the International Organization of Securities Commissions (IOSCO), at iosco.org, and the version binding in India is SEBI's. Where a bilateral currency or rate arrangement is in play, the Reserve Bank of India governs it, at rbi.org.in.

Everything worked above happens to sit inside exchange tradedstandardised so that every copy of the contract is identical, then traded openly instead of negotiated one to one machinery, where the standardisation is what makes a defined set of obligations possible in the first place. Standardising the contract makes the netting easy, and easy netting is still not payment.

The reference asset, the position holder and all four obligations worked above are invented.
