Hedging Through Exchange-Traded Currency Derivatives

Hedging is the practice of taking an offsetting position in a derivative to protect an existing foreign‑exchange exposure from adverse movements in the spot rate. In the Indian context, an exporter expecting USD receipts or an importer needing INR to pay for foreign goods can lock in a rate today by using exchange‑traded currency futures listed on NSE or BSE.

Exchange‑traded futures differ from over‑the‑counter forwards because they are standardized contracts, centrally cleared, and subject to daily mark‑to‑market (MTM). These features reduce counterparty risk, improve liquidity, and make the contracts suitable for retail and institutional investors alike – a point frequently examined in NISM questions.

For the exam, you must be able to explain the rationale behind hedging (risk reduction), identify the appropriate contract specifications (size, expiry, tick size), and perform basic calculations such as the hedge ratio and MTM profit or loss. Mis‑understanding the direction of the hedge (protective vs. speculative) is a common trap.

• Protective hedge – opposite position to the underlying exposure.
• Speculative hedge – same direction as the exposure, used to profit from expected moves.

Each Indian currency future has a fixed contract size (e.g., USD 100,000) and a tick size of INR 0.05 per USD, which translates to a minimum cash movement of INR 5,000 per tick. The contracts are available for tenors up to 12 months, and they are settled in cash based on the closing spot rate on the expiry day.

Margin is posted in INR and consists of an initial margin (IM) and a daily variation margin (VM). The IM is a percentage of the contract's notional value, typically 7‑9% as prescribed by SEBI. The VM reflects the daily MTM profit or loss and is settled through the participant’s margin account.

Liquidity is highest for the front‑month contracts, which means tighter bid‑ask spreads and lower transaction costs. The NISM exam often asks you to pick the most liquid contract for a short‑term hedge or to calculate the cost of carry using the implied interest rate embedded in the futures price.

The hedge ratio tells you how many futures contracts are needed to offset the foreign‑exchange exposure. Because contracts are indivisible, the ratio is rounded to the nearest whole number, usually upward for a protective hedge to ensure full coverage.

When the exposure is in the opposite direction (e.g., a foreign investor hedging INR exposure), the same formula applies but the sign of the position (long vs. short) changes. The NISM exam may present a scenario where the exposure is a payable in USD, requiring a long futures position.

Remember that the hedge ratio does not consider transaction costs or basis risk. Those adjustments are evaluated separately, often through a ‘cost of hedge’ calculation in advanced questions.

Mark‑to‑Market (MTM) is the daily process of revaluing the futures position at the prevailing settlement price. Any gain or loss is transferred to the participant’s margin account as a variation margin (VM). If the VM is negative, the participant must top‑up the margin to maintain the required level.

The Initial Margin (IM) is a fixed percentage of the contract's notional value, set by SEBI. For a USD 100,000 contract at a futures price of INR 75, the notional is INR 7,500,000. With an IM of 8%, the required cash is INR 600,000.

Exam questions often ask you to compute the total cash outflow for a hedge, which includes the IM and any VM that may be required after a price move. Forgetting to add the VM is a common mistake that leads to an incorrect answer.

The sign of the result indicates whether the hedge generated a gain (positive) or a loss (negative). In a protective hedge, a loss on the futures position is offset by a gain on the underlying foreign‑exchange transaction, thereby stabilising the overall cash flow.

When the futures price moves in the opposite direction to the exposure, the MTM loss must be funded through the margin account. The NISM exam may present a multi‑day scenario where you need to track cumulative VM and determine the net cash impact.

Always align the direction of the futures position with the exposure: short futures for expected foreign‑currency inflows, long futures for expected outflows. Mixing up the direction leads to a reverse hedge, which the exam explicitly tests.

One frequent error is treating the hedge ratio as a percentage rather than a number of contracts, leading to under‑ or over‑hedging. Always convert the ratio into whole contracts before calculating margin.

Another mistake is ignoring the expiry mismatch. If the exposure settles before the futures expiry, the hedge must be unwound early, incurring a MTM settlement that may differ from the original expectation.

Students also overlook the impact of transaction costs such as brokerage and exchange fees. While small, they are part of the total cost of hedging and can be the deciding factor in multiple‑choice questions that ask for the most cost‑effective hedge.

• Do not assume futures price equals spot price; the difference reflects the cost of carry.
• Never forget to adjust the hedge when the exposure amount changes during the contract life.

SEBI’s “Regulation of Derivatives Market” (circa 2020) mandates that all participants in currency futures must be registered as a ‘Category I’ or ‘Category II’ participant, maintain a minimum net worth, and adhere to position limits (e.g., 5% of the open interest for a single client).

Clients must also complete KYC, provide a risk‑disclosure statement, and sign a margin agreement. The margin requirement is monitored daily, and any breach leads to an automatic square‑off by the clearing corporation.

For the NISM exam, remember the key compliance points: registration, net‑worth criteria, position limits, and daily MTM settlement. Questions may ask which of the following is NOT a SEBI requirement – watch out for distractors that mix RBI guidelines with SEBI rules.
