Determination of Settlement Obligations

A settlement obligation is the amount of Indian rupees that a participant must either pay or receive when a currency derivative contract is settled on its expiry date. Since ETCDs are cash‑settled, the physical delivery of the foreign currency does not occur; instead, the profit or loss is realised in INR based on the difference between the contract price and the final settlement price.

The final settlement price, also called the closing price, is derived from the spot rate of the underlying currency on the expiry day as published by the exchange. The contract price (or strike price) is the agreed‑upon rate at which the contract was entered. The difference between these two rates, multiplied by the contract size, determines the cash flow.

For the NISM exam, you will often be asked to calculate the exact rupee amount that a long or short position owes. Remember that the sign of the result matters: a positive amount means the participant receives money, while a negative amount indicates a payment obligation.

• Settlement Obligation = (Final Settlement Price – Contract Price) × Contract Size
• All calculations are performed in INR; the foreign currency amount is embedded in the contract size.

On the expiry day, the exchange publishes the final settlement price for each currency pair. Each participant’s position is then valued using the cash‑settlement formula. The exchange’s clearing corporation aggregates all positions and performs a net‑ting process, which means that only the net amount (overall payable or receivable) is transferred between the participant and the clearing house.

Before the net‑ting, participants must have posted the required initial and variation margin. If the net settlement results in a payment to the participant, the clearing house credits the participant’s margin account. Conversely, if the participant owes money, the amount is debited from the margin account, and additional funds may be called to meet the shortfall.

From an exam perspective, remember that the clearing corporation guarantees settlement, so the calculation does not involve counter‑party credit risk. Questions may ask you to identify who receives the payment (long or short) after net‑ting, or to compute the net amount after offsetting multiple positions.

A long position holds the right to benefit when the settlement price exceeds the contract price. If (S_T - K) is positive, the long receives the calculated amount; if it is negative, the long must pay the absolute value to the short.

A short position experiences the opposite. A positive (S_T - K) means the short owes the long, while a negative difference results in a payment to the short. The formula remains the same; only the interpretation of the sign changes with the position.

Exam questions frequently present a scenario with multiple contracts and ask you to compute the net payable for each participant. Keep a clear table of long and short quantities, apply the formula to each, and then sum the signed amounts to obtain the net obligation.

The National Stock Exchange (NSE) or Bombay Stock Exchange (BSE) clearing corporation acts as the central counter‑party. It steps in between the buyer and seller, guaranteeing that the settlement will be honoured even if one party defaults.

During the net‑ting process, the clearing house aggregates all long and short obligations across participants. The resulting net amount for each participant is settled through the participant’s margin account. This mechanism reduces the number of fund transfers and minimizes systemic risk.

For the exam, remember that the clearing corporation’s guarantee means that settlement calculations do not require a credit‑risk adjustment. Questions may ask you to identify the entity that receives the payment before net‑ting (the clearing house) and the entity that finally receives or pays the net amount (the participant).

Because the settlement price is directly tied to the spot exchange rate on expiry, any movement in the INR/USD (or other currency pair) immediately impacts the settlement amount. A stronger INR (lower INR per USD) reduces the payable for a long position and increases the payable for a short.

Traders often use the term "basis point move" to describe small changes. One basis point equals 0.0001 INR per unit of foreign currency. For a contract size of 1,000,000 USD, a 1‑bp move translates to an INR 100 change in settlement amount (0.0001 × 1,000,000).

Exam setters love to test your ability to convert basis‑point moves into rupee amounts. Remember the simple conversion: Settlement Change = Basis‑point Change × Contract Size × 0.0001.
