NISM Series XVI – Commodity Derivatives: Chapter 5 – Uses of Commodity Derivatives (Short Notes)

This is Part 5 of 7 in our complete NISM Series XVI Commodity Derivatives short notes series. This chapter covers the key uses of commodity derivatives — hedging (long and short hedge), speculation, arbitrage, spread trading, and basis risk. These topics carry significant weight in the NISM XVI exam.

1. Hedging What Is Hedging?

Hedging means taking a position in the derivatives market that is opposite to an existing position in the physical (spot) market, with the objective of reducing or eliminating the risk of adverse price movements.

A hedger enters into a derivatives contract to protect an existing physical exposure from price fluctuations. Hedgers are not trying to profit from the derivatives trade itself — they are using it as price insurance.

Two Basic Hedging Strategies:

1. Offsetting Hedge: A hedge taken to offset (neutralize) a price risk that has already arisen from a physical commodity contract.
2. Price Lock-In Hedge: A hedge used to lock in an attractive price level for a future transaction — for example, a farmer can lock in the selling price of their upcoming harvest during the sowing season, even before the crop is ready.

2. Long Hedge and Short Hedge Using Futures Long Hedge

• Used when a participant needs to buy a commodity in the future but does not currently own it.
• Strategy: Buy (go long) futures contracts to lock in today's price for a future purchase.
• The participant is naturally "short" the commodity (they need to buy it) and offsets this by going long in futures.
• Common users: Processors who need to buy raw materials in the future (e.g., a flour mill buying wheat futures).
• Long hedgers benefit from a weakening of basis (futures price rising relative to spot price).

Short Hedge

• Used when a participant already owns or expects to produce a commodity and wants to protect against a potential price fall.
• Strategy: Sell (go short) futures contracts to lock in today's price for a future sale.
• The participant is naturally "long" the commodity and offsets this by going short in futures.
• Common users: Farmers who want to protect the price of their upcoming harvest, or processors/manufacturers holding finished goods inventory.
• Short hedgers benefit from a strengthening of basis (spot price rising relative to futures price).

Summary Table:

3. Hedge Ratio

The hedge ratio tells a hedger exactly how many futures contracts to buy or sell to effectively cover their physical market exposure.

It accounts for the fact that spot and futures prices do not always move perfectly in sync — they have different volatilities. The hedge ratio neutralizes this volatility difference.

Formula:

Hedge Ratio = Coefficient of Correlation (Spot & Futures) × (Standard Deviation of Change in Spot Price ÷ Standard Deviation of Change in Futures Price)

• A hedge ratio of 1.0 means buying one futures contract for every physical unit of exposure.
• A ratio greater than 1.0 means more futures contracts are needed to fully hedge.
• A ratio less than 1.0 means fewer futures contracts are needed.

4. Benefits of Hedging

• Price risk is significantly minimized.
• Facilitates better production planning, business planning, and cash flow management.
• Provides price certainty for budgeting purposes.
• Enables firms to focus on core business operations without being distracted by commodity price volatility.

5. Limitations of Hedging

• Price risk cannot be completely eliminated — only reduced.
• Basis risk always remains (the risk that the futures price will not move exactly in sync with the spot price).
• Transaction costs are incurred each time a futures position is opened and closed.
• Margin requirements must be maintained, which can create cash flow pressure — especially when the futures position moves against the hedger in the short term.

6. Speculation What Is Speculation?

Speculation involves actively trading commodities or commodity derivatives with the primary goal of making quick profits from price fluctuations. Speculators do not have any underlying physical commodity need — they never intend to take or give delivery.

Types of Speculators:

Role of Speculators in Commodity Markets:

While speculation is often viewed negatively, speculators play a vital role by providing liquidity to the market and absorbing the price risk that hedgers want to transfer. Without speculators, hedgers would find it difficult to find counterparties for their trades.

7. Arbitrage What Is Arbitrage?

Arbitrage involves making simultaneous purchases and sales in two different markets to profit from existing price differences, without bearing any market risk. The goal is to earn a riskless profit from the price gap between two markets or two contracts.

Types of Arbitrage in Commodity Markets: A. Spot vs Futures Arbitrage

This opportunity arises when the actual traded futures price deviates from its fair value (spot price + cost of carry):

• Cash-and-Carry Arbitrage: When the futures price is higher than the fair value, an arbitrageur can:
  • Buy the commodity in the spot market using borrowed funds
  • Simultaneously sell the futures contract
  • Earn a riskless profit when the futures contract is settled at the higher futures price
• Reverse Cash-and-Carry Arbitrage: For those who already hold the commodity asset. When the futures price is lower than spot price + cost of carry:
  • Sell the commodity in the spot market
  • Simultaneously buy the futures contract
  • Profit from the price differential

B. Futures vs Futures Arbitrage

This involves exploiting price differences between futures contracts of the same commodity with different expiry months, or between the same commodity traded on two different exchanges.

8. Basis — Revisited

Basis is one of the most important concepts in both hedging and speculation:

Basis = Spot Price – Futures Price

• A positive basis (spot > futures) = Backwardation market
• A negative basis (futures > spot) = Contango market
• Basis risk = The risk that the basis will change unexpectedly, reducing the effectiveness of a hedge

As a futures contract approaches expiry, the basis moves toward zero (convergence). This predictable narrowing of basis is what makes futures contracts effective as hedging tools.

9. Spread Trading

Spread trading involves simultaneously taking opposite positions in two related futures contracts — one long and one short — to profit from the expected change in the price difference (spread) between them.

It is lower risk than outright directional trading because the spread position is less volatile than holding a single outright futures position.

Types of Futures Spreads:

Lower Margin for Spread Trading:

Because spread positions are less volatile than outright positions (the net settlement amount is smaller), exchanges set lower margin requirements for spread trades than for single outright futures positions.

Note: Spread trading typically results in thinner profit margins compared to outright directional trading. Success requires a good understanding of the relationship between the two contracts being spread.

10. Summary: How Commodity Derivatives Are Used

Quick Revision – Key Exam Points

• Hedging does not eliminate all risk — basis risk always remains.
• Long hedgers benefit from weakening basis; short hedgers benefit from strengthening basis.
• Cash-and-carry arbitrage: Buy spot + sell futures (when futures price > fair value).
• Reverse cash-and-carry: Sell spot + buy futures (when futures price < fair value).
• Spread trading carries a lower margin requirement than outright trading.
• Buying a spread = Buy near-month + Sell far-month.
• Selling a spread = Sell near-month + Buy far-month.
• An inter-commodity spread involves two different but economically related commodities.
• An intra-commodity spread involves the same commodity with different expiry months.

Practice Questions (NISM XVI Pattern)

1. A farmer expects to harvest wheat in three months. He is worried about a price decline. What hedging strategy should he use?
   Answer: Short hedge — sell (short) wheat futures to lock in today's price.
2. What is the formula for calculating the hedge ratio?
   Answer: Hedge Ratio = Correlation (Spot & Futures) × (Std Dev of Spot Change ÷ Std Dev of Futures Change)
3. What is the key difference between cash-and-carry arbitrage and reverse cash-and-carry arbitrage?
   Answer: Cash-and-carry = buy spot + sell futures (used when futures > fair value). Reverse = sell spot + buy futures (used when futures < fair value).
4. Why does spread trading attract lower margin requirements?
   Answer: Because the net settlement value of a spread position is less volatile than an outright futures position, reducing exchange risk exposure.
5. What is basis risk?
   Answer: The risk that the futures price will not move in perfect tandem with the spot price, leaving the hedger partially exposed despite having a hedge in place.
6. Name the two types of commodity spreads.
   Answer: Intra-commodity spread (same commodity, different expiry months) and Inter-commodity spread (different but related commodities).
