Novation: How the Clearing House Becomes the Counterparty

Novation is a substitution of contracts: one becomes two. The moment a trade matched on Kaveri Stock Exchange Limited, an invented exchange, is novated, whatever stood between the buyer and the seller is ended, and the clearing corporation stands in as the buyer to the seller and as the seller to the buyer. From that instant, neither side depends on the other for anything at all.

There is something awkward about a matched trade, and it is worth sitting with for a moment before any machinery arrives. Two orders met on a screen. Nobody chose anybody. The person on the other side of a purchase is whoever happened to be selling at that price at that instant, and the buyer will never learn their name, their circumstances or whether they can actually deliver what they have just agreed to deliver. A promise is only ever as good as the party making it. The buyer has just accepted a promise from a party it did not select and cannot assess.

Every arrangement in this part of the market is an answer to that one problem, and novation is the sharpest of them. Novation does not make the stranger more reliable. By putting a single institution into the middle of every trade, one everybody in that market has already agreed to deal with, novation removes the need for anybody to have an opinion about the stranger at all. How that substitution works, what it costs the institution that performs it, and the exact point at which it stops are the three things to hold on to.

What is novation, and what exactly is being replaced?

Novation is a substitution of contracts, and the plainest way to hold it is as an arithmetic of agreements. Before: one contract, between the buyer and the seller. After: two contracts, one between the buyer and the clearing corporation that settles trades matched on Kaveri Stock Exchange Limited, and one between the seller and that same clearing corporation. One agreement went in and two came out.

The original deal is not there any more, so nothing was added on top of it: something was replaced, not reinforced. Almost every wrong reading of novation comes from getting that one point backwards. Novation is not insurance sitting behind the trade. Novation is not a promise bolted onto the agreement that was already there. Novation is not a pot of money standing quietly behind two parties who are still, underneath it all, dealing with each other. The original agreement is finished.

The everyday version is closer than it looks. A tenancy that is properly transferred rather than sublet works the same way. When the transfer is done properly, the old agreement is not still sitting in a drawer with a guarantee stapled to it. It is over. There is now an agreement between the outgoing tenant and the landlord that has been ended, and a fresh agreement between the incoming tenant and the landlord that has been made. If somebody later asks the outgoing tenant to pay the rent, the answer is not that they would rather not. The answer is that there is nothing left to pay it under. Change the nouns and that is novation.

What happens to the contract the two sides started with?

The original contract is extinguishedEnded completely, with nothing of the original agreement left in the background to fall back on. A word from the law of contracts rather than from markets.. Extinguished is the technical word, and it is worth learning. The ordinary words people reach for instead are all softer than the truth. The contract is not paused, not stood down, not held in reserve. The contract stops existing. The seller can no longer bring a claim against the buyer, and the buyer can no longer bring a claim against the seller, for the simple reason that there is nothing left between them to bring a claim under.

After the substitution, whether the party on the other side of the trade is any good stops being either side's problem, and it stops completely rather than mostly. The version people usually carry away is weaker than that. The other side does not become less important, nobody is watching it on either party's behalf, and there is no cushion if it fails. There is no other side. The party being dealt with is the institution in the middle, and the stranger the order met has been dealt out of that half of the arrangement entirely.

Notice how much that simplifies. Before the substitution, a market of many participants requires each of them to hold a view about each of the others, and to hold it fast enough to trade in a fraction of a second. Nobody does this. Nobody could. Each participant instead agrees, once and in advance, to deal with one institution, and the market works because that single agreement stands behind every trade any of them will ever do there.

What is a central counterparty?

A central counterparty is an institution that becomes the counterparty to each side of every trade it clears. A definition made entirely of a verb is worth reading twice. The definition says nothing about what the institution is called, what it is licensed as, how large it is or what its building looks like. An institution is a central counterparty because it does that one thing, and everything else about such an institution follows from having done it.

Two consequences arrive immediately, and both belong in the same breath rather than the pleasant one on its own. The first is that every participant faces the same institution, so no participant has to form a view of any other. The second is that every exposure which used to run in a web between hundreds of parties now runs like the spokes of a wheel into one centre.

Putting the exposures in one place is what makes them manageable, and it is also what makes that place matter to everybody, and both halves of that sentence are true at once. An account that gives only the first half is selling something. ConcentrationThe effect of many separate exposures running into one place instead of being spread between many. Concentration is neither good nor bad in itself, and it changes what has to be watched and where. is not a criticism here and it is not a compliment either. Concentration is a description of a shape, and the shape has been chosen deliberately. The alternative, a web of unassessable promises between strangers, is worse. But it does mean that the questions worth asking about this market are questions about one institution rather than about hundreds, and a reader who has understood the shape knows where to point them.

The numbers are pleasant, so work the counting yourself with a small market. Six times five divided by two is fifteen, and fifteen is the number of distinct pairs six participants dealing bilaterally can form. Every one of those fifteen links is a promise somebody has to be able to assess. Route the same six through one institution instead and there are six links, one for each participant. Fifteen relationships have become six, and the six are all with the same party. Each participant now has one relationship to understand rather than five.

What is the clearing corporation holding once it has stepped in?

Take the worked trade. Rupees show the position more plainly than words do. A buyer has agreed to take 8,000 shares of Suvarna Commercial Bank Limited, an invented listed bank, at Rs 105.00/- a share. Multiply it out: 8,000 by Rs 105.00/- is Rs 8,40,000/-. Rs 8,40,000/- is the whole trade. The exchange matched it and stopped there, and the clearing corporation that settles trades matched on Kaveri Stock Exchange Limited has now stepped into the middle of it.

Read the position it is left with in the security first. The clearing corporation has bought 8,000 shares from the seller and sold 8,000 shares to the buyer. The two legs cancel exactly. The clearing corporation holds no shares and wants no shares, and if the price of Suvarna Commercial Bank Limited moves by any amount in any direction, it makes and loses nothing on the security itself. The clearing corporation is flatWhat has been bought and what has been sold are the same thing in the same quantity, so there is no net position. A price move then produces neither a gain nor a loss on that holding..

Now read the same trade in credit, and it is a different picture entirely. The clearing corporation is owed Rs 8,40,000/- by the buyer, and it owes Rs 8,40,000/- to the seller. On paper those cancel too. In substance the two amounts do not cancel at all. Each rests on a different person, and no arrangement anywhere makes the seller's claim shrink when the buyer disappoints.

A matched book in the security and an unmatched book in credit is the whole of what a central counterparty carries, and every other thing it does exists to deal with the second half. Put it as a pair of outcomes and it is unmissable. If both sides perform, the clearing corporation ends the day exactly where it began, having taken a fee and moved some property. If one side does not perform, the clearing corporation still has to perform to the other, and it has to do so out of resources that have nothing to do with the party that let it down.

Why does margin follow from novation rather than sitting beside it?

The next piece of machinery follows from what has just been established rather than having to be introduced. The clearing corporation has taken on an obligation to perform to whichever side is still standing. The clearing corporation took that obligation on by choice, at the instant of the substitution, and for a party it cannot refuse to face. So it needs something in hand from each side before anybody asks it to perform. Margin is that something: money or securities placed with the clearing corporation against obligations that have not yet been settled.

The substitution creates the exposure, and the institution takes margin because it created that exposure. Margin is not a separate precaution sitting beside novation but the direct consequence of it. Read that way, margin is never an administrative nuisance. A market with no central counterparty has no centre, so it needs no margin at one. Put a centre in and margin becomes unavoidable in the same movement.

At the scale of the institution rather than one trade, the picture is a pair of amounts with different jobs. The clearing corporation that settles trades matched on Kaveri Stock Exchange Limited holds margins of Rs 11,000 crore, and behind those margins sits a settlement guarantee fundResources held in common so that one participant's failure is not paid for by participants who did nothing wrong. The contents of such a fund, and its size, are set by SEBI. of Rs 2,750 crore. Divide rather than take the multiple on trust: Rs 11,000 crore over Rs 2,750 crore is 4.00 times, and the base in that sentence is the fund, not turnover and not anything else. Margins against the fund and margins against turnover are entirely different statements, and the words look nearly identical. The base therefore belongs inside the sentence.

Both arithmetic steps above can be redone with a pen: 8,000 multiplied by Rs 105.00/- gives Rs 8,40,000/-, and Rs 11,000 crore divided by Rs 2,750 crore gives 4.00 times.

The two amounts are not two sizes of the same thing. Margin is collected participant by participant against each participant's own unsettled obligations, so it is money attached to a name. The fund is pooled, so it is money attached to the market. The contents of each, the amount required, and the way any collateralProperty placed with somebody as security against what is owed to them. Which property may be used, and how its value is discounted, is set by SEBI and covered separately. placed as margin is valued are set by the Securities and Exchange Board of India (SEBI) at sebi.gov.in.

What happens when a member fails, and why is the order the protection?

Start with what a clearing memberA firm permitted to settle directly with the clearing corporation and answerable to it for the accounts it clears, including accounts belonging to people who are not themselves members. is. The word is about to do a lot of work. A clearing member is a firm allowed to settle directly with the clearing corporation, and answerable to it for the accounts it clears. Novation runs between the clearing corporation and those firms. When one of them fails, the clearing corporation is still obliged to perform to everybody on the other side of everything that firm was involved in, and it has to find the resources somewhere.

The clearing corporation does not decide where, on the day. The losses are met from a set of resources in a stated order, fixed in advance and published, and the sequence is a matter of record before anybody needs it. The first thing reached belongs to the failing firm itself, before anything belonging to anybody who did nothing wrong. Reaching the failing firm first is the one part of the arrangement worth carrying away.

The order is the protection, and the total is not. A large pool of resources with no agreed order is worse than a smaller pool with one, and the reason is about people rather than arithmetic. The moment a member fails is precisely the moment when nobody would agree whose money goes first, when everybody with resources in the pool has an excellent argument for why theirs should be reached last, and when there is no time at all to hear any of those arguments. An order settled in calm and written down converts an argument into an instruction.

The household version is unglamorous and exact. A group of neighbours puts money into a common repair pot. If the roof goes and nobody wrote down who pays first, the meeting about the roof takes three weeks and the rain does not wait. If the sequence was written down when everybody was cheerful, the first rupee moves the same afternoon. Nothing about the size of the pot changes either outcome.

The order itself, the number of steps in it, the contents of each step and the size of any threshold inside it are all set by SEBI at sebi.gov.in, and all of it is revised. A printed step would not be slightly out of date. A printed step would be wrong, in the one place where somebody would repeat it without checking.

Where does the substitution stop?

The boundary of the substitution is the part most often missed, so it is worth being slow about. Novation runs between the clearing corporation and its clearing members. Novation does not run past them. A person who trades through a firm has a contract with that firm, and the firm carries the obligation to the clearing corporation. Two links, not one, and they are governed by different things.

For a client trading through a firm, the counterparty is that firm, and it is not the clearing corporation, however often the market is described as one where every trade is stood behind. Followed along the chain, the reason is obvious rather than technical. The clearing corporation admitted the firm, holds the firm to its rules, holds margin from the firm and will pursue the firm. The clearing corporation never admitted the client, has no record of the client as a party, and has no contract with the client to breach.

So the protections that actually matter to a client sit at a different link from the one everybody talks about. At that link, the question is how the client's money and the client's securities are kept apart from the firm's own. The separation has a name: segregationKeeping a client's money and a client's securities separate from a firm's own, so the firm's troubles do not become the client's. The practical requirements are set by SEBI.. How that separation has to work, what has to be shown to the client about it, and how it is supervised are set by SEBI at sebi.gov.in. The link the question belongs at is the part people get wrong.

Three different companies do the three jobs, and merging them is the commonest slip. The three jobs stay straight only if they are kept apart. Kaveri Stock Exchange Limited matches. The clearing corporation stands between the two sides and becomes the counterparty to each. The depositoryThe institution holding securities in electronic form against a name, so a transfer is a change to a record rather than a movement of paper. Covered separately. holds the record of what is held and by whom. None of the three does another's work, and a sentence that lets one of them do so has quietly lost the reason the other two exist.

What has to be true for the substitution to hold at all?

The substitution is easy to hear as reassurance, so turn it into something checkable instead. The substitution holds while four conditions hold, and each of them is a question with an answer rather than a feeling. A substitution only ever happens inside the set of things an institution has agreed to stand in the middle of, so the trade has to be of a kind the clearing corporation actually clears. Both sides have to reach it through members bound by the same rules, agreed in advance rather than negotiated in the moment. The margin has to genuinely be there, rather than being an entitlement the institution has not collected. And the institution itself has to be standing.

Novation moves the question from whether the other side is any good to whether the clearing corporation is, and that is a better question rather than no question at all. This is the honest close to the mechanism, and it deserves to be said plainly. An institution of this kind is visible, examined, and required to publish things about itself, so the stranger nobody could assess has been replaced by somebody who can be. An answerable question in place of an unanswerable one is an enormous improvement. An answerable question is not the same as the absence of a question, and any account that says otherwise has skipped the fourth condition.

How does somebody with an account actually use any of this?

Who sets the order and the thresholds inside it?

Four of the requirements met so far are not the clearing corporation's to set. An authority sets them and revises them, so a written value would be incorrect rather than merely ageing. The rows below carry the authority where a value would otherwise sit, and the value column stays empty. Which requirement exists, who is responsible for it and where the current answer lives all survive every revision, so the sheet is genuinely useful in that state.

A row with a number typed into it is wrong the day the number moves. A row with an address in it never goes wrong at all. The emptiest row in the sheet is therefore the most important one in it: the order in which a failed member's resources are used is the sharpest idea in this part of the market, and not one step of it is written above.
