Clearing, Settlement and Risk Management is 10 marks in NISM Series VIII — but in question banks it consistently punches above that, because the material is precise and easy to ask about. It is also the chapter candidates most often leave until last and then run out of time on.
It is dense, but almost all memorisation. That makes it reliable marks once the hours go in.
Novation: what the clearing corporation actually does
When a trade is executed, the clearing corporation interposes itself between the two sides. It becomes the buyer to every seller and the seller to every buyer.
This single mechanism is what separates an exchange-traded future from a forward. Both leave you exposed to price movement; only the exchange removes counterparty risk. If the party on the other side of your trade defaults, it is not your problem — it is the clearing corporation's.
That is also why the margin framework exists. Having guaranteed settlement, the clearing corporation must protect itself.
The margin stack
Four things, and the exam expects you to tell them apart.
Initial margin — collected upfront, sized to cover the likely adverse move on the position over the relevant horizon. It is a deposit, not a cost: it is returned when the position closes, and in the trader's books it is a current asset rather than an expense.
Exposure margin — an additional layer over and above initial margin, providing further cushion.
Extreme loss margin (ELM) — covers losses beyond what the initial margin's statistical model anticipates. The name is the definition.
Mark to market — not a deposit at all, but the actual daily gain or loss, settled in cash each day against the settlement price. Debited from the margin account when the market moves against you, credited when it moves for you.
The distinction that gets tested: initial margin is collected in advance against a possible loss; mark to market settles a loss that has already happened.
SPAN
SPAN is a portfolio-based margining system. Rather than margining each position in isolation, it computes the worst plausible loss on the whole portfolio across a range of price and volatility scenarios, and margins that.
The practical consequence — and the exam point — is that a hedged portfolio attracts less margin than the sum of its parts would, because offsetting positions genuinely reduce risk.
Daily settlement, and why it matters
Futures positions are settled every day, not at expiry. Each day's gain or loss is settled in cash against the settlement price.
Two things follow:
- A margin call can arrive long before you close a position. If mark to market debits push the balance below the maintenance level, you top up or the position may be squared off.
- Your total profit is unchanged by all this. It remains (exit − entry) × lot size × contracts. Daily settlement pays it out in instalments rather than one lump at the end.
Settlement at expiry
Cash settlement exchanges only the difference in value. Physical settlement delivers the underlying shares against payment, as the exchange specifies for stock derivatives.
Index derivatives can only ever be cash settled — an index is not a deliverable thing.
The final settlement price is tied to the underlying on expiry day, as specified by the exchange, which is what forces convergence between the derivative and the cash market.
When someone defaults
The clearing corporation has guaranteed settlement, so a member default must be absorbed rather than passed on. It works through a defined sequence — the defaulter's own margins and deposits first, then the layers of the guarantee fund behind them.
Learn the order; that is what gets asked, more often than the amounts.
How to study it
Do not read this chapter once and move on. Make yourself a one-page table of the four margin types with a one-line definition each, and reproduce it from memory until it comes cleanly. Nearly every question here is a definition or a distinction.
And remember Series VIII carries 25% negative marking: on a margin question you are unsure of, eliminate before you commit.
