Crude Oil Option Expiry: Convert Options to Futures on MCX

Crude oil options on MCX, like all Indian F&O contracts, have a finite life. Expiry day isn't just the end of a contract; it's a critical juncture. For option sellers, it means managing potential assignments. For buyers, it's about realizing profit or accepting loss. Understanding these mechanics prevents unwelcome surprises. Most retail traders aim to close their positions before expiry to avoid the complexities of assignment or settlement. The key is knowing your options—literally.

Key Concepts at Expiry

Several actions are possible as expiry nears. You can offset your position by taking an equal and opposite trade, locking in your profit or loss. Alternatively, you can rollover your position to the next contract month, maintaining your market view. If neither is done, the contract is settled. For options, this means assignment for the seller if in-the-money (ITM), or expiry worthless for the buyer if out-of-the-money (OTM).

Let's analyze Abhijit's situation. He is short 3 lots of Crude Oil 5600 Put options (Expiry: March 2024). He received ₹171 premium per lot. The lot size for MCX Crude Oil is 100 barrels. Abhijit expects Crude Oil futures to fall further. Suppose on expiry, Crude Oil futures close at ₹5300.

A Put option is 'in-the-money' (ITM) when the strike price is above the futures price. Here, 5600 (strike) > 5300 (futures price). So, the 5600 PE is ITM.

Calculating Initial Premium Received

Total premium received = Premium per lot × Lot size × Number of lots.

Total Premium = ₹171 × 100 × 3 = ₹51,300.

This ₹51,300 is credited to Abhijit's account on trade initiation.

When an option expires in-the-money, the seller faces assignment. For a short Put, this means the seller must 'buy' the underlying at the strike price. Abhijit sold the 5600 PE. On expiry at ₹5300, he is obligated to buy Crude Oil futures at ₹5600 per barrel.

This assignment effectively converts his option position into a futures position. He is now long 3 Crude Oil futures contracts at an entry price of ₹5600.

Conversely, if Abhijit had sold a 5600 Call option and it expired ITM (futures price > 5600), he would be obligated to 'sell' the underlying at ₹5600. This would result in a short futures position at ₹5600.

The crucial point for conversion is the settlement price. This is the official price determined by MCX at the end of the trading session on expiry day. This price dictates whether an option is ITM and thus, whether assignment occurs.

In Abhijit's case, the settlement price is ₹5300. His 5600 PE is ITM by ₹300 (₹5600 - ₹5300). The effective futures price he is 'long' is the strike price: ₹5600. This ₹5600 becomes the cost basis for his newly acquired futures position.

The strike price of the option (₹5600) becomes the entry price for the resulting futures contract. The settlement price (₹5300) is the actual market price at expiry, reflecting the final value of the underlying.

The ₹51,300 premium Abhijit received initially is his to keep, regardless of assignment. This reduces his overall cost basis. However, the settlement price determines the profit or loss on the futures leg.

Abhijit's effective entry into the futures contract is ₹5600. The settlement price is ₹5300. His loss on the futures leg is calculated as:

Loss per barrel = Entry Price - Settlement Price = ₹5600 - ₹5300 = ₹300.

Total futures loss = Loss per barrel × Lot size × Number of lots.

Total futures loss = ₹300 × 100 × 3 = ₹90,000.

Now, let's look at the net P&L:

Net P&L = Premium Received - Futures Loss.

Net P&L = ₹51,300 - ₹90,000 = -₹38,700.

The converted futures contract will belong to the same expiry cycle as the option contract. If Abhijit traded the March 2024 Crude Oil option, his assigned futures position will be for the March 2024 expiry contract. Traders who wish to continue their position beyond this expiry month must actively rollover the newly acquired futures contract to a later month. This involves closing the current month's futures and opening a position in the next available contract month.

Rollover costs are influenced by the difference in prices between the expiring contract and the next month's contract. This difference is often due to contango (futures price increases with longer expiry) or backwardation (futures price decreases with longer expiry).

MCX Crude Oil futures often exhibit contango due to storage costs, insurance, and interest rates. This means rolling over a long futures position in Crude Oil can incur a cost (paying the difference between the current and next month's contract price). Conversely, rolling a short position might generate income.

Nifty futures, being an index, do not have storage costs. Their rollover costs are primarily driven by interest rates and dividends. Typically, the cost to roll Nifty futures is lower than that of commodities like Crude Oil, especially when there's a steep contango in the commodity market.

For Indian retail traders, capitalizing on contango or backwardation in commodity futures presents unique challenges. The primary instruments are traded on MCX. While MCX offers futures and options on commodities like Crude Oil, Natural Gas, and Gold, accessibility and understanding remain key.

Margin requirements for commodity futures can be substantial. For example, as of early 2024, a naked short Crude Oil futures position might require margins around ₹1.28 Lakhs, differing from Nifty's approximately ₹1.1 Lakhs margin for a naked short call or put. These margins can change based on market volatility and exchange rules.

Furthermore, understanding the global supply-demand dynamics, geopolitical factors, and storage capacities that influence commodity prices requires dedicated research. Many retail traders find it simpler to focus on indices like Nifty and BankNifty where information is more readily available and price movements are less volatile compared to the global commodity markets.
