Spot and Derivatives Trading in Commodities

The spot market is where a commodity is bought and sold for immediate delivery, usually within two business days in India. Prices quoted in the spot market are called spot prices and reflect the current supply‑demand balance, transportation costs, and prevailing market sentiment.

Transactions in the spot market are settled in cash (or physical delivery) on the settlement date. Because settlement occurs quickly, participants need sufficient liquidity to meet the payment obligation. The spot price serves as the benchmark for pricing many derivative contracts, making it a cornerstone concept for the exam.

Exam tip: Questions often ask you to identify whether a given transaction is a spot trade or a derivative trade. Look for keywords such as “immediate delivery”, “cash settlement”, or “settlement within T+2”.

Commodity derivatives are financial contracts whose value is derived from an underlying commodity’s spot price. The two most common types are futures contracts and options contracts. A futures contract obligates the holder to buy or sell a specified quantity of a commodity at a predetermined price on a future date, while an option gives the holder the right, but not the obligation, to do so.

Both futures and options are traded on recognized exchanges such as MCX (Multi Commodity Exchange) and NCDEX (National Commodity & Derivatives Exchange). They are standardized in terms of contract size, tick size, and expiry dates, which simplifies clearing and settlement under SEBI regulations.

For the NISM exam, focus on the contract specifications, the role of the clearing corporation, and how margin works. Typical questions may ask you to match a contract feature (e.g., “standardized lot size”) with its definition.

While the spot market deals with immediate exchange of the commodity, derivatives markets involve a contractual agreement that postpones delivery and payment. This temporal shift creates distinct risk profiles: spot traders face price risk at the moment of trade, whereas derivative traders manage future price risk through hedging.

Liquidity also differs. Spot markets can be less liquid for certain agricultural commodities, leading to wider bid‑ask spreads. Derivatives benefit from exchange‑driven liquidity, tighter spreads, and the presence of market makers.

From an exam perspective, remember that margin, marking‑to‑market, and the concept of basis are unique to derivatives and never appear in pure spot‑trade questions.

The basis is the difference between the spot price (S) of a commodity and its futures price (F) for the same delivery month. It reflects storage costs, convenience yield, and interest rates. A positive basis (S > F) often indicates a tight market, whereas a negative basis suggests abundant supply.

Basis is crucial for hedgers because it determines the effectiveness of a futures hedge. If the basis widens unexpectedly, the hedge may under‑perform. The NISM exam frequently asks you to calculate basis or interpret its movement.

Remember: Basis = Spot price – Futures price. The sign of the basis tells you whether the market is in contango (negative basis) or backwardation (positive basis).

When you trade futures on MCX or NCDEX, you must post an initial margin – a security deposit set by the exchange to cover potential losses. Throughout the contract’s life, the exchange performs daily mark‑to‑market (MtM) settlement, crediting or debiting your account based on price movements.

The MtM profit or loss for a single day is calculated as the change in futures price multiplied by the contract size. If the price moves against your position, a variation margin call is issued, and you must add funds to maintain the required margin level.

Exam questions often present a price series and ask you to compute the cumulative MtM profit, the amount of variation margin required, or the impact of a margin call on the trader’s cash balance.

SEBI (Securities and Exchange Board of India) regulates commodity derivatives through the Commodity Derivatives Market Regulations, 2015. All participants must be registered as either a trader, broker, or client with a recognized exchange and must comply with KYC, AML, and margin norms.

Clearing is performed by the exchange’s clearing corporation, which guarantees contract settlement and monitors margin. The exchange also publishes daily price limits, position limits, and position‑day‑closing‑price (PDCP) to curb market manipulation.

For the exam, you should know the key regulatory bodies (SEBI, exchange clearing corporation), the mandatory registration categories, and the purpose of daily price limits and position limits.

1. Mixing up basis sign. Remember that basis = Spot – Futures. A positive result means backwardation; a negative result indicates contango.

2. Ignoring margin calls. When calculating MtM profit, many candidates forget to add the variation margin that must be deposited, leading to an under‑estimation of cash outflow.

3. Assuming all futures are physically settled. In India, most commodity futures are cash‑settled; physical delivery is optional and only for specific contracts.

4. Using spot price for futures valuation. Futures price incorporates cost of carry; using spot price directly in a futures‑pricing question will give a wrong answer.
