Commodity Options Trading Guide India

Commodity Options

Options on commodities follow the same foundational principles as equity options, and any trader familiar with options on stocks or indices will find the conceptual framework largely transferable. The critical distinction that sets commodity options apart from their equity counterparts, however, lies in the nature of the underlying asset, and understanding this distinction is essential before engaging with commodity options in practice.

Black 76

In Indian equity markets, options are written on the spot price of the underlying asset. A call option on a pharmaceutical company such as Biocon derives its value from the spot price of that stock. Nifty 50 options derive their value from the spot level of the Nifty 50 index. The standard Black-Scholes model is used to price these options and calculate their Greeks, because the underlying in each case is a spot price with well-understood statistical properties.

Commodity options in India operate differently. Because India does not have a functioning spot market for physical commodities such as Crude Oil, Gold, or Natural Gas, commodity options are not written on a spot price. Instead, they are options on futures contracts. The underlying for a Crude Oil option on MCX is the Crude Oil futures contract, not a spot Crude Oil price. The Crude Oil futures contract itself derives its value from international benchmark prices on NYMEX. A commodity option is therefore a derivative of a derivative, a structure that is entirely standard in international commodity markets but requires a clear conceptual adjustment for traders more accustomed to equity options.

This structural difference has a direct implication for options pricing. The Black-Scholes model, which assumes the underlying is a spot price earning a risk-free rate of return, is not the appropriate pricing model for options on futures. The correct model for options written on futures contracts is the Black 76 model, a variation developed by Fischer Black that modifies the treatment of the compounded risk-free rate to reflect the fact that futures contracts do not require an upfront capital outlay in the same way that spot purchases do. The practical consequence is clear: applying a standard Black-Scholes calculator to commodity options variables will produce inaccurate premium estimates and unreliable Greeks. Traders seeking to price commodity options or assess their theoretical value must use a Black 76 calculator specifically, several of which are freely available online.

Contract Specifications

The framework for commodity options on MCX has developed gradually since the introduction of Gold options as the initial instrument. The structure is expected to expand progressively to other actively traded commodities as regulatory comfort and market participation grow. The specifications described below reflect the framework applicable to Gold options, which serves as the template for commodity options more broadly.

Option types available are standard calls and puts. The lot size for commodity options mirrors the lot size of the corresponding futures contract, as these are options on futures rather than on the spot commodity. All standard order types are permitted, including Immediate or Cancel, Stop Loss, Stop Loss Market, Good Till Cancelled, Regular, and Limit orders. Exercise style is European, meaning options can only be exercised at expiry and not before, consistent with the exercise style of currency options discussed in earlier chapters. Margin requirements follow the SPAN plus Exposure margin structure for option writing, whilst option buyers are required to pay the full premium upfront. For Gold options specifically, the last trading day falls three days before the last tender day of the corresponding futures contract.

Regarding available strikes, the exchange lists 31 strikes in total for each expiry series: one At the Money strike, 15 strikes above it, and 15 strikes below it.

Understanding Option Moneyness in Commodity Options

Traders familiar with equity options will be accustomed to the standard moneyness classifications of At the Money, In the Money, and Out of the Money. Commodity options introduce an additional classification, Close to Money, which requires careful attention because it carries specific settlement implications.

The moneyness definitions for commodity options are as follows.

At the Money refers to the strike closest to the Daily Settlement Price of the commodity on expiry. In a given series, this will be a single strike level.

Close to Money refers to the two strikes immediately above and the two strikes immediately below the At the Money strike, producing a total of five strikes classified as Close to Money including the At the Money strike itself.

Out of the Money retains its standard definition: call option strikes above the At the Money level and put option strikes below it are Out of the Money and expire worthless.

In the Money also retains its standard definition: call option strikes below the At the Money level and put option strikes above it are In the Money.

Working through a concrete example clarifies how these classifications interact. Suppose the Daily Settlement Price of a commodity on expiry is Rs. 100, and strikes are spaced Rs. 10 apart.

The At the Money strike is Rs. 100. The Close to Money strikes are Rs. 80, Rs. 90, Rs. 100, Rs. 110, and Rs. 120, representing two strikes above and two strikes below the At the Money level. All call options with strikes above Rs. 100 are Out of the Money and worthless. All put options with strikes below Rs. 100 are Out of the Money and worthless. All call options with strikes below Rs. 100, including the Rs. 80 and Rs. 90 Close to Money strikes, are In the Money. All put options with strikes above Rs. 100, including the Rs. 110 and Rs. 120 Close to Money strikes, are In the Money.

Settlement Mechanics and the Devolvement Process

The settlement mechanism for commodity options introduces two specific procedural requirements that traders must understand clearly to avoid unintended outcomes at expiry.

For In the Money options that are not classified as Close to Money, automatic devolvement into an equivalent futures position occurs at expiry unless a Contrary Instruction is submitted. Devolvement means that the option is converted into a futures position at the option’s strike price. A trader holding an In the Money call option at a strike of Rs. 70, for instance, would automatically receive a long futures position at Rs. 70 at expiry. If this outcome is not desired, perhaps because the cost of holding the futures position, including applicable taxes and charges, makes exercise economically unattractive, the trader must submit a Contrary Instruction through the trading terminal before expiry to prevent the automatic devolvement from occurring.

For Close to Money options, the settlement process works in the opposite direction. These options are not automatically devolved. Instead, the holder must submit an Explicit Instruction through the trading terminal if they wish to exercise the option and receive the corresponding futures position. In the absence of an explicit instruction, a Close to Money option will be treated as worthless at expiry, regardless of how much intrinsic value it appears to carry. This is a critical operational point: a trader holding a Close to Money call or put option who fails to submit an explicit instruction will forfeit the option’s value entirely.

The reasoning behind this two-tier structure is pragmatic. Devolvement into a futures position creates a new obligation with margin requirements and ongoing mark-to-market settlement. There may be circumstances in which the costs associated with holding that futures position, including brokerage, taxes, and the capital tied up in margin, exceed the intrinsic value of the option itself. Both the Contrary Instruction and Explicit Instruction mechanisms exist to give traders control over whether devolvement occurs, ensuring that no trader is forced into a futures position they did not intend to hold.

For those building a comprehensive understanding of derivatives markets across equities, currencies, and commodities, mastery of these settlement mechanics is as important as understanding options pricing and strategy construction. The practical consequences of misunderstanding the devolvement process at expiry can be significant, and awareness of the procedural requirements is an essential component of responsible commodity options trading.
