Currency Options Hedging for ACCA AFM

Updated 11 October 2026 · Fact-checked

A currency option gives you the right, but not the obligation, to buy or sell currency at a fixed rate on or before a set date, in return for a premium. You fix the worst-case rate, keep any upside, compare the outcome with the market rate, and include the premium cost.

Understand Currency Options and Hedging Strategies

A currency option protects you against an adverse exchange rate move but lets you gain if the rate moves in your favour. You pay a premium up front for this. A forward contract fixes the rate and removes the upside. An option keeps the upside, and the premium is the price of that.

A call option gives the right to buy the currency. A put option gives the right to sell it. Decide from your cash flow. If you must pay foreign currency later, you need to buy it, so you want a call. If you will receive foreign currency, you need to sell it, so you want a put. Always think of the option from the viewpoint of the currency you are buying or selling.

The exercise price (strike) is the rate you can lock in. A strike that is better for you costs a higher premium. A strike that is worse for you costs less. You exercise only if the option rate beats the spot rate on the day. If the spot rate is better, you let the option lapse and deal in the market.

OTC options are tailor-made with a bank. You choose the amount, date and strike. They suit odd amounts and dates, and the premium is paid at the start. Exchange-traded options have standard contract sizes, standard expiry dates and fixed strikes. They need margin and can be sold before expiry. Because of standard sizes you usually cannot hedge the exact amount, so you buy a whole number of contracts and deal with the remainder at spot or by another hedge.

In the exam, the premium is a real cost. You must convert it into the same currency and date as the hedged flow. Many questions then ask you to compare the option with a forward, a money market hedge or leaving the exposure open, and to advise.

Key rules to remember

Choosing call or put: Need to buy foreign currency → call. Need to sell foreign currency → put.; Decide this first. The direction is from your own cash flow.
Exercise decision: Exercise if option rate is better for you than the spot rate on the expiry date; otherwise let it lapse.; The exercise decision compares strike with spot only; the premium is paid regardless of whether you exercise, so it does not affect the decision.
Premium cost: Total premium = premium per unit × amount hedged (or × number of contracts × contract size); Make sure the premium currency matches the quote. Convert at the spot rate on the date you pay it.
Number of exchange-traded contracts: Contracts = amount to hedge ÷ contract size (round to a whole number); Check which currency the contract size is in. Handle any unhedged remainder separately.
Net outcome with option: Net receipt = amount × rate used − premium (receipts); Net payment = amount × rate used + premium (payments); Here the rate is home currency per unit of foreign currency (for example ₹ per $1). Use the option rate if exercised, or the spot rate if not. Divide only if the rate is quoted the other way round, as foreign currency per unit of home currency. If the premium is paid now, finance it forward to the transaction date when the question gives an interest rate.

How to solve Currency Options and Hedging Strategies questions

Use this method for any currency option question, OTC or exchange-traded.

1Identify whether you are buying or selling the foreign currency, and so whether you need a call or a put.
2Read the quote direction carefully. Check the base currency of the rate, the premium and the contract size.
3Pick the strike and expiry. Use the first expiry on or after the transaction date, and the strike the question requires.
4Calculate the premium in total and convert it into the home currency at the stated spot rate. If an interest rate is given, carry it forward to the transaction date.
5For each possible spot rate, compare it with the strike. Exercise only if the strike is better; otherwise use the spot rate.
6Work out the net home-currency result including the premium. For exchange-traded options, treat the unhedged remainder separately.
7Compare with the forward and money market results. Comment on cost, flexibility, certainty and the likely rate view, then give a recommendation.

Quickest way: Three-line option check

When to use it: Use when time is short and you are asked for the outcome at one or two given spot rates.

Write the direction: call to buy, put to sell. Write the strike next to the spot rate.
Compare strike and spot: for a payment, the lower home-currency cost per unit of foreign currency is better; for a receipt, the higher home-currency amount per unit is better.
Add or subtract the premium once, then state the net figure and the decision.

Common mistakes in Currency Options and Hedging Strategies

Choosing a call when a put is needed, or the reverse.
Students think of the home currency instead of the foreign currency being bought or sold.
Fix: Ask: am I buying or selling the foreign currency? Buying means a call. Selling means a put.
Ignoring the premium or leaving it in the wrong currency.
The exercise decision looks complete without it, so the premium is forgotten.
Fix: Always compute the total premium, convert it and include it in the final outcome. Add the interest cost if the question gives a rate.
Letting the premium decide whether to exercise.
Students mix up the decision with the total cost.
Fix: Decide to exercise on strike versus spot only. The premium is already paid. Then include it in the net result.
Hedging the exact amount with traded options.
Students forget contract sizes are standard.
Fix: Divide by contract size, round to whole contracts, and show the remainder as unhedged or covered another way.
Recommending the option purely because it is flexible.
Students describe features but do not link them to the scenario.
Fix: Tie the advice to the company's risk view, cost of the premium, and certainty needs. Compare with the forward result with numbers.

Worked examples

Example 1

A company will receive $1,000,000 in 3 months. It buys an OTC dollar put option at a strike of ₹80.00 per $1 for a premium of ₹0.50 per $1, paid now. Ignore interest. Calculate the net rupee receipt if the spot rate in three months is (a) ₹78.00 and (b) ₹83.00.

Show the solution

The company receives dollars and must sell them, so it needs a put option on dollars.
Total premium = $1,000,000 × ₹0.50 = ₹5,00,000.
(a) Spot ₹78.00 is worse than the strike ₹80.00 for a seller. Exercise the option. Receipt = $1,000,000 × 80.00 = ₹8,00,00,000.
Net for (a) = ₹8,00,00,000 − ₹5,00,000 = ₹7,95,00,000.
(b) Spot ₹83.00 is better than the strike. Let the option lapse and sell at spot. Receipt = $1,000,000 × 83.00 = ₹8,30,00,000.
Net for (b) = ₹8,30,00,000 − ₹5,00,000 = ₹8,25,00,000.

Answer: (a) Net receipt ₹7,95,00,000 with the option exercised. (b) Net receipt ₹8,25,00,000 with the option lapsed and dollars sold at spot.

Example 2

An Indian importer must pay $620,000 in three months. It uses exchange-traded dollar call options. Each contract is for $50,000 and the strike is ₹82.00 per $1. The premium is ₹0.60 per $1. Spot in three months is ₹85.00. Calculate the number of contracts, the total premium, and the rupee cost of the hedged and unhedged parts.

Show the solution

The importer must buy dollars, so it needs call options.
Contracts = $620,000 ÷ $50,000 = 12.4. Round down to 12 contracts, covering $600,000.
Unhedged amount = $620,000 − $600,000 = $20,000.
Premium = 12 × $50,000 × ₹0.60 = $600,000 × ₹0.60 = ₹3,60,000.
Spot ₹85.00 is worse than the strike ₹82.00 for a buyer, so exercise. Cost of hedged part = $600,000 × 82.00 = ₹4,92,00,000.
Unhedged part is bought at spot: $20,000 × 85.00 = ₹17,00,000.
Total cost = ₹4,92,00,000 + ₹3,60,000 + ₹17,00,000 = ₹5,12,60,000.

Answer: Buy 12 call contracts. Total premium is ₹3,60,000. Hedged part costs ₹4,92,00,000 plus the premium of ₹3,60,000. Unhedged part, bought at spot, costs ₹17,00,000. Total rupee cost is ₹5,12,60,000.

Exam tips

State clearly whether you need a call or a put, and why, in the first line of your answer.
Show the premium calculation and the exercise decision for each spot rate. Marks are often given for each step.
For exchange-traded options, always show the contract rounding and deal with the unhedged remainder.
Finish with a comparison with forwards and money market hedges and a clear recommendation tied to the scenario. This earns professional skills marks.
Check which currency the premium and contract size are quoted in before multiplying.

Currency Options and Hedging Strategies: frequently asked questions

How do I decide whether to exercise a currency option?

Compare the strike with the spot rate on the expiry date. Exercise if the strike gives you a better result than the market. If spot is better, let the option lapse and deal at spot. The premium does not affect this decision.

What is the difference between a call and a put in currency hedging?

A call gives the right to buy the currency and a put gives the right to sell it. A company that will pay foreign currency needs a call. A company that will receive foreign currency needs a put.

What is the difference between OTC and exchange-traded currency options?

OTC options are agreed with a bank and can match the exact amount and date. Exchange-traded options have standard sizes, dates and strikes, so the hedge is rarely exact. Traded options can be sold before expiry and need margin.

Why choose an option instead of a forward contract?

An option fixes the worst-case rate but lets you gain if the market moves in your favour. You pay a premium for that. A forward costs nothing upfront but locks you in even if the market moves your way.
