Long Hedge and Short Hedge Strategies Using Futures

A hedge is a risk‑management technique that reduces the uncertainty of future cash‑flows by taking an opposite position in a related futures contract. In commodity markets, the underlying asset of the futures contract is the same physical commodity that the business will buy or sell later.

The key idea is that price movements in the spot market are offset by opposite movements in the futures market. If the spot price falls, a long futures position gains value; if the spot price rises, a short futures position gains value. This offsetting effect stabilises the effective price that the hedger ultimately pays or receives.

For the NISM exam, you must remember that hedging is a *risk‑reduction* activity, not a speculative bet. SEBI’s definition of a hedger (as per the Commodity Derivatives Regulations) emphasises the intention to protect against price volatility, which is the lens exam questions use.

• Hedging aims to lock in a price or reduce price variance.
• The opposite position in futures creates the offsetting payoff.

A long hedge is employed by entities that anticipate purchasing a commodity at a later date – for example, a food‑processing company that will need sugar in three months. The firm goes long (buys) futures contracts today to lock in the purchase price.

Implementation steps: (1) Estimate the exposure – the quantity and value of the commodity to be bought. (2) Choose a futures contract with a delivery month that matches the expected purchase date. (3) Compute the hedge ratio and the number of contracts needed. (4) Maintain the position until the contract expires or is offset, monitoring basis risk.

In the exam, you may be asked to calculate the effective price after a long hedge or to decide whether a long hedge is appropriate given the timing of the exposure. Typical traps include forgetting to adjust for contract size or ignoring basis risk when the spot‑future price differential changes.

• Long hedge locks in a maximum purchase price.
• Effective price = Futures price at initiation + Basis at expiry (if any).

A short hedge is used by producers or holders of a commodity who plan to sell it later – such as a farmer expecting to harvest wheat in six months. The holder sells futures contracts now to secure a minimum selling price.

Implementation steps mirror the long hedge: (1) Quantify the exposure (expected quantity to be sold). (2) Select a futures contract whose delivery month aligns with the expected sale. (3) Compute hedge ratio and required contracts. (4) Monitor the position, especially for basis changes, until the futures are closed or settled.

Exam questions often present a scenario where the spot price at expiry is lower than the futures price at initiation. The correct answer shows that the short hedge compensates for the lower spot price, delivering the pre‑agreed futures price (adjusted for basis) to the seller.

• Short hedge guarantees a minimum selling price.
• Effective price = Futures price at initiation – Basis at expiry (if any).

Even a perfectly calculated hedge can be affected by basis risk – the difference between the spot price and the futures price at the time of contract expiry. In India, the basis can change due to storage costs, transportation bottlenecks, or seasonal demand‑supply shifts.

Margin requirements introduce cash‑flow considerations. Both long and short hedgers must post initial margin and maintain variation margin, which can strain liquidity if price volatility spikes. Failure to meet margin calls forces the position to be liquidated, potentially at an unfavorable price.

Regulatory limits also apply. SEBI caps the open interest for certain commodity futures and requires position limits for large traders. While these limits are not part of the exam’s numeric calculations, candidates should be aware that exceeding them invalidates a hedge.

• Basis risk can erode the intended price lock.
• Margin calls can create unexpected cash outflows.
• Regulatory position limits must be respected.
