Clearing Member: The Role, the Obligations and the Margin Chain

A clearing member is the firm that faces the clearing corporation directly and answers to it for every trade beneath it. A trading member executes orders; a clearing member settles them and carries the obligation to pay. Margin climbs the chain from client to broker to clearing member to the clearing corporation, and the duty to pay climbs with it: each layer answers for the one below.

Somebody has to be on the hook. When two strangers agree a price for shares, the agreement is worth nothing until money and shares actually change hands, and between the handshake and the handover there is a gap in which either side can vanish. The institution that closes that gap has to know exactly whom it can call. No guarantor can call millions of households, so it builds a short list of firms that have lodged money with it, signed its rules and accepted that they will pay whether or not their own customers do. The firms on that short list are clearing members. What they promise, what they collect, and what happens on the day somebody underneath them cannot pay is what the whole arrangement turns on.

Five questions sit inside the role: which firm executes and which firm settles, why a guarantor deals with a dozen members instead of thousands of individuals, what a clearing member is actually obliged to do, how Rs 10,00,000 of margin travels up four layers and shrinks to Rs 8,00,000, and who pays when Sohan Malhotra's account cannot meet a call.

What is a clearing member, and how does it differ from a trading member?

Buying a washing machine shows most of it. A household calls a dealer, agrees the model and the price, and the dealer confirms the order. Matching a buyer to a seller at a price is one job. Then a warehouse van arrives, the machine is carried in, the money is collected and the paperwork is signed. Making the exchange actually happen, and carrying the loss if it goes wrong in transit, is a second job. Sometimes the dealer and the warehouse are the same business. Often they are not, and the buyer never meets the second one at all.

A trading member puts orders into the market and gets them matched; a clearing member takes responsibility for the settlementThe stage after a trade is agreed, when money actually moves from the buyer and the asset actually moves from the seller. A trade is not finished until it is settled. of those trades and answers to the clearing corporation for them. The trading member is admitted to the exchange, and its licence is about conduct in the market: entering orders, quoting, handling client instructions. The clearing member is admitted to the clearing corporation, and its licence is about money: lodging collateral, meeting calls on time, and delivering shares and cash on the settlement day whatever has happened to the client who caused the trade.

The two roles often sit in one firm. A broker large enough to be admitted to both will trade and clear its own business. A client rarely hears the second name. Smaller brokers do not clear at all; they trade, and then hand their trades to a clearing member who settles them under an arrangement between the two firms. There are also firms that do the reverse, taking on the clearing for many brokers and never entering an order themselves. The exact membership categories and the conditions for each are set by the exchange and the clearing corporation, and are covered under market infrastructure rather than here. One test settles the vocabulary: if a trade fails to settle, whom does the clearing corporation telephone? The clearing member, every time.

Why does the clearing corporation face members rather than clients?

Picture a wedding with 400 guests and a caterer holding a Rs 3,00,000 order. The caterer does not open 400 accounts, does not check 400 credit histories and does not chase 400 people for money. The caterer deals with one host. The host collects nothing formal from the guests and may never be reimbursed by any of them, but the caterer's contract is with the host, and the host is on the hook for the whole bill. The host is a member: one manageable counterparty who has agreed to answer for a crowd the caterer cannot see.

A guarantee is only as good as the guarantor's ability to check and enforce it, and checking is only possible against a small number of parties whose finances can be watched continuously. Count what the alternative would cost. Suppose 3,600 households trade through 40 brokers, and those 40 brokers clear through 12 clearing members. Facing clients directly, the clearing corporation would carry 3,600 relationships: 3,600 sets of documents, 3,600 credit judgements, 3,600 collateral accounts to value every day. Facing members, it carries 12. Each of those 12 watches its own brokers, and each broker watches its own clients. The work does not disappear; it is pushed down to the layer that is closest to the person and can actually see whether that person is good for the money.

There is a second reason, and it is about time rather than count. The whole point of a central guarantee is speed: nettingAdding up everything owed in both directions between two parties and moving only the difference, instead of paying every amount separately. everything down to one payment per member per settlement, taken at a fixed hour. A single missed payment at that hour has to be identified, covered and replaced within minutes. A payment run at a fixed hour cannot be chased across thousands of individual bank accounts. Twelve firms can be chased. Each has lodged collateral in advance, and each knows that failure ends its membership.

What is a clearing member actually obliged to do?

The promise is short and hard: settle every trade accepted, on time, whatever has happened underneath. Everything else in the obligation list follows from that one sentence. Because the promise is unconditional, the clearing member must hold money against it in advance, must know at all times how big its exposure is, and must be able to tell whose money is whose when things go wrong.

A clearing member's obligations are not a list of good practices. Each is an unconditional promise, enforceable by the clearing corporation on the same day it is broken. Read the table below as promises rather than duties, because the difference matters: a duty can be discussed, and a promise backed by lodged collateralSomething of value handed over in advance so the other side can help itself to it if the party that lodged it fails to pay. Cash, government securities and approved shares are common forms. is simply executed. The clearing corporation does not need the member's agreement to use collateral it already holds.

Two of these deserve a second look. The separation promise sounds administrative and is the one clients should care about most. Separation is what makes a client's collateral identifiable rather than part of a general pool on the day a firm fails. And the monitoring promise is the one that makes the whole structure work: the clearing member cannot pass a loss down, so it has every reason to stop the loss forming. A member that lets a broker run positions far larger than the collateral behind them has already accepted the loss without noticing. The member's own trading competes for the same collateral that stands behind its clients, so a proprietaryDone by a firm with its own money and for its own account, rather than on behalf of a client. book adds one more layer to watch.

What is the margin chain, and which way does it flow?

Think about a group tour. Each traveller pays the agent Rs 25,000 up front. The agent must pay the airline Rs 20,000 a seat by a fixed date, no exceptions. The agent collects more than it must pay, and it collects earlier, for one plain reason: on the day the airline has to be paid, one traveller's payment may have bounced, and the agent still has to send the full amount. The extra is not profit. The extra is the agent's cushion against the layer below it failing at exactly the wrong moment.

Margin travels up the chain from client to broker to clearing member to clearing corporation, and at every step the layer collects at least as much as it must pass on, keeping the difference as its own cushion. That is why the numbers shrink as they climb. Sohan Malhotra's purchase of Rs 40,00,000 of listed shares carries the illustration: the clearing corporation asks 20 per cent of the positionThe size of what somebody currently holds or has committed to, measured in value. A Rs 40,00,000 purchase of shares is a Rs 40,00,000 position. value as margin, the clearing member asks 22.5 per cent of the broker, and the broker asks 25 per cent of Sohan. Every one of those percentages is an illustration chosen to make the arithmetic visible, not a rule and not a market figure. Sohan posts Rs 10,00,000. The broker passes Rs 9,00,000 to the clearing member and holds Rs 1,00,000 of its own cushion. The clearing member passes Rs 8,00,000 to the clearing corporation and holds Rs 1,00,000. Rs 10,00,000 leaves the client; Rs 8,00,000 arrives at the top; Rs 2,00,000 sits in the middle as two cushions.

The shrinkage is the part people misread, so look at it on its own. Because the top of the chain carries the guarantee, it is tempting to think the top must hold the most. The clearing corporation holds the least of the three figures. The reason is that the clearing corporation is protected by everything below it as well as by what it holds: the member's cushion, the broker's cushion, the client's collateral, and the fact that each of those layers loses its business if it fails. The layer nearest the risk holds the most collateral, and the layer furthest from it holds the least. The inversion is worth sitting with.

What happens when a client cannot pay, and what happens when a member cannot?

One point governs everything else. The obligation never travels downward. When the market moves against Sohan Malhotra and a call is made, the call reaches him from his broker, and if he does not meet it, nothing about the clearing corporation's claim changes. Its claim was always against its member, for the full amount, on the settlement deadline. A failure below simply means somebody above pays out of their own pocket and then goes looking for the money.

Each layer answers for the layer below it, so a failure is absorbed upward until it reaches a layer that can pay, and the clearing corporation is only ever exposed to its own member. Follow it with the numbers. Sohan Malhotra's shares are marked to marketRevalued at the current market price rather than at what was paid. Losses and gains are recognised as they happen rather than when the asset is sold. and fall 35 per cent, a loss of Rs 14,00,000 on a Rs 40,00,000 position. The Rs 10,00,000 of margin the broker holds from him is applied first, leaving Rs 4,00,000. If Sohan cannot find that Rs 4,00,000, the broker must, from its own funds, before the pay-inThe fixed hour by which money and securities have to reach the clearing corporation for that settlement. Miss it and the trade is treated as failed. deadline. The clearing corporation is paid in full and never learns that a client failed. The broker now has an ordinary debt to recover from Sohan Malhotra through ordinary means, and it may sell the shares it is holding for him first.

Push it one layer further. Suppose that Rs 4,00,000 was one of many, and the broker also cannot pay. The clearing member now uses the collateral the broker lodged with it, Rs 9,00,000 in the worked case, and if the hole is deeper than that, the clearing member pays the rest itself. Push it one layer further again and the clearing member fails. Now the clearing corporation uses the Rs 8,00,000 the member had lodged and, beyond that, reaches for its own pooled protections. The clearing corporation also tries to portMove a client's open positions and the collateral behind them from a failing firm to a healthy one, so the client is not closed out. the clients of the failed member to a healthy member, and porting works only where their collateral was reported separately and can be identified. The guarantor's own defences after that point, and the order it draws on them, are set out under the clearing corporation.

Where does Sohan Malhotra sit in the chain, and what does his purchase cost in margin?

Put the whole thing in one place. Sohan Malhotra buys Rs 40,00,000 of listed shares through his broker. The broker is a trading member of the exchange but not a clearing member, so it hands the trade to a clearing member under a standing arrangement between the two firms. Sohan has never heard the clearing member's name, has no contract with it, and cannot telephone it. His entire relationship is with the broker. The clearing member's entire relationship is with the clearing corporation. The two relationships, taken together, explain almost every surprise a client meets in a market failure.

Sohan Malhotra sits at the bottom of a four layer chain in which he can be called by only one party and can call only one party, and the chain above him is invisible to him until something breaks. The table below sets out the whole position, and every figure in it can be rebuilt from the Rs 40,00,000 purchase and the three illustrative rates.

How do a client, a broker's risk desk and a clearing member actually use this?

A household investor uses it in exactly two ways, and both take about ten minutes. First, find out from the account opening papers or the contract note which clearing member the broker clears through. The named firm is the party standing in front of the clearing corporation for those trades. Second, check that the collateral lodged against the account is reported to the clearing corporation in the client's own name rather than sitting in a pool. The reporting check is what turns a bad week at a broker into an inconvenience instead of a loss, and it is far more useful than reading the guarantee language on a statement.

A broker's risk desk uses it as an arithmetic problem it must never lose. The desk knows what it must pass upward, sets what it collects from clients above that figure, and watches the difference through the day. When a client's position grows faster than the collateral behind it, the desk either calls for more or closes part of the position, and the second option is unpopular and necessary. Every layer in this chain is really running the same calculation: what do I owe upward today, what do I hold from below, and how fast is the gap between the two moving.

A clearing member uses it as a selection problem. The member cannot watch thousands of individual clients, so it watches the brokers it has taken on: how concentrated their client base is, how quickly they collect, whether their own trading book is competing with client collateral for the same cash. A clearing member that accepts a broker on price alone has bought that broker's worst client without ever seeing the account. The arrangement between a broker and a clearing member is therefore negotiated as carefully as a loan, with limits, reporting and the right to refuse a trade.

Sohan Malhotra, his broker, the clearing member and the clearing corporation are invented.
