Contract Specifications for Commodity Derivatives Contracts

Contract specifications are the predefined parameters that describe every aspect of a commodity derivatives contract. They are set by the exchange (e.g., MCX) in consultation with SEBI and remain unchanged for the life of the contract.

These specifications ensure that all market participants trade a homogeneous product, eliminating disputes over quantity, quality or settlement. For the exam, SEBI‑mandated uniformity is frequently tested.

Key reasons the exam focuses on specifications: they appear in multiple‑choice questions, they form the basis for margin calculations, and they help you quickly eliminate wrong answer options by matching numbers to the correct commodity.

Contract Size – the quantity of the underlying commodity covered by one futures contract (e.g., 10 000 kg of wheat). It is expressed in standard units such as metric tonnes or kilograms.

Tick Size – the minimum price movement allowed by the exchange, quoted in rupees per unit (e.g., Rs 0.25 per kg). It determines the smallest price change a trader can record.

Tick Value – the monetary value of one tick movement, calculated as Tick Size × Contract Size. This figure is crucial for profit‑loss and margin estimation.

Price Quotation – the method by which the contract price is quoted (e.g., Rs per metric tonne). Different commodities may use different quotation units.

Contract Months – the set of expiry months offered for a commodity (e.g., March, May, July, September, December for gold). SEBI mandates that at least three consecutive months be listed for each commodity.

Settlement Type – either physical delivery of the commodity or cash‑settlement based on a reference price. The type is fixed in the contract specification.

Underlying Grade & Delivery Location – the exact quality (grade) of the commodity and the approved warehouse or exchange‑approved delivery point. These details prevent grade‑mismatch disputes.

Each commodity has a standard contract size that reflects typical market liquidity and storage considerations. For agricultural commodities, the size is often expressed in metric tonnes (e.g., 1 MT of soybean), while metals are usually in kilograms or ounces.

The exchange decides the size after consulting producers, traders and logistics providers. A larger size reduces transaction costs but may limit participation of small traders.

For the NISM exam, you must memorize the contract size for the most‑traded commodities: gold (1 kg), crude oil (100 barrels), wheat (10 000 kg), and copper (5 MT). Any deviation in a question signals a trick.

Contract months are the specific months in which a futures contract expires. SEBI requires at least three consecutive months for each commodity, but many exchanges list up to twelve months for highly liquid contracts.

Expiry is usually the last business day of the contract month. The final settlement price is derived from the spot price on that day.

Exam questions may present a list of months and ask you to identify the missing month or the month with the highest open interest. Remember the typical pattern for each commodity (e.g., gold – March, June, September, December).

Price quotation indicates how the contract price is expressed. Metals are quoted in rupees per 10 g (e.g., gold), while agricultural commodities use rupees per metric tonne or per kilogram.

The unit matters when converting tick value to rupees. For example, a tick size of Rs 0.05 per 10 g of gold translates to a different rupee amount than Rs 0.05 per kg of wheat.

In the exam, always check the quotation unit before performing any multiplication. A common mistake is to treat a per‑kg tick as per‑ton without conversion.

Physical settlement requires the actual delivery of the commodity at a pre‑approved warehouse. Cash settlement settles the contract based on a reference price, avoiding the logistics of moving the commodity.

SEBI mandates that commodities with storage constraints (e.g., perishable agricultural produce) often have cash‑settlement options, whereas metals typically allow physical delivery.

Exam focus: Identify which settlement type applies to a given contract and understand the impact on margin requirements. Physical contracts usually demand higher initial margin due to delivery risk.

Each contract specifies an approved delivery location, often a major exchange‑approved warehouse or a designated port. The location ensures transparent pricing and reduces transportation disputes.

Grade specifications define the exact quality parameters (e.g., moisture content for wheat, purity for gold). The contract will list the grade code and reference standards such as IS or AFA.

For the exam, remember that grade and location are fixed; any deviation in a question indicates a scenario testing your knowledge of contract terms versus market practice.

Use the mnemonic C‑T‑V‑P‑M‑S‑G to recall the order of specifications: Contract size, Tick size, Tick value, Price quotation, Contract months, Settlement type, Grade & location.

When a question provides two of the three (tick size, contract size, tick value), quickly compute the missing one using the simple multiplication formula.

Always scan the specification table in the question stem; many wrong answers arise from overlooking the unit of quotation or the contract month pattern.
