Forward Contract vs Money Market Hedge: The ACCA AFM Mistake to Avoid

Ask an ACCA AFM candidate how to hedge a foreign currency exposure and most will happily reel off either the forward contract formula or the money market hedge steps, whichever one they revised more recently. That is exactly the trap the exam sets. A foreign exchange risk question rarely asks for one technique in isolation; it asks which hedge is better, and answering that properly means calculating both and comparing the results. Candidates who calculate only their preferred method, however accurately, leave the comparison marks on the table.

Why the exam wants both, not just one

Advanced Financial Management questions on foreign exchange risk are built around a decision: should the treasury team use a forward contract, a money market hedge, or leave the exposure unhedged? That decision can only be made by working out the outcome of each hedge in the home currency and comparing them side by side. A technically correct forward contract calculation, on its own, only ever earns the marks allocated to that one technique — it cannot earn the marks allocated to the comparison and the recommendation, because those marks exist specifically to reward evidence that you have weighed the alternatives.

How a forward contract hedge works

A forward contract locks in an exchange rate today for a transaction that will settle at a fixed date in the future, removing exchange rate uncertainty entirely. For a company expecting to receive a foreign currency amount, the bank quotes a forward rate for converting that currency back to the home currency, and the company simply applies that agreed rate to the amount it expects to receive. It is quick to calculate and, because the rate is fixed in advance, there is no dependence on interest rate data at all, which is part of why it is often the technique candidates reach for first. For a fuller explanation of the mechanics and how banks price a forward rate, see this guide to how forward contracts work.

How a money market hedge works

A money market hedge (MMH) achieves the same certainty as a forward contract, but by using the money markets rather than a forward rate. For a foreign currency receipt, the steps are:

• Borrow an amount in the foreign currency today, sized so that the loan plus interest exactly equals the amount due to be received.
• Convert the borrowed foreign currency into the home currency immediately, at today's spot rate.
• Place the converted home currency on deposit until the receipt date.
• When the foreign currency receipt arrives, use it to repay the foreign currency loan; the home-currency deposit, plus interest earned, is the hedged amount.

For a foreign currency payment, the logic runs in reverse: borrow in the home currency, convert to the foreign currency at spot, deposit the foreign currency until it is needed, and use the deposit to settle the payment.

Worked example: receipt of US dollars

A UK company expects to receive $2,000,000 from a US customer in three months and wants to compare a forward contract against a money market hedge.

Data available: spot rate $1.2500 per £1; three-month forward rate $1.2400 per £1; three-month USD borrowing rate 1.5%; three-month GBP deposit rate 1.0%.

Forward contract outcome

The company sells the expected $2,000,000 forward at $1.2400 per £1:

$2,000,000 ÷ 1.2400 = £1,612,903

Money market hedge outcome

• Borrow USD now, sized so that principal plus 1.5% interest equals $2,000,000: $2,000,000 ÷ 1.015 = $1,970,443 borrowed today.
• Convert to GBP at spot: $1,970,443 ÷ 1.2500 = £1,576,354.
• Deposit the GBP for three months at 1.0%: £1,576,354 × 1.01 = £1,592,118.
• In three months, the $2,000,000 receipt repays the USD loan exactly, leaving the £1,592,118 deposit as the hedged amount.

Comparing the two hedges

In this example the forward contract delivers roughly £20,785 more than the money market hedge, so it is the better choice for this company on this data. Change the interest rates or the forward rate and the ranking can flip, which is precisely why the calculation has to be done both ways every time rather than assumed from experience with previous questions.

The exam-technique trap, and how to avoid it

The most common mark loss in this area is not a calculation error, it is an incomplete answer. A candidate who is confident with money market hedge mechanics will sometimes calculate only the MMH, state a hedged amount, and move on, without ever setting up the forward contract calculation to compare against it. The reverse happens just as often with candidates who default to the forward rate because it needs no interest rate data. Either way, the marks for the comparison and the recommendation go unclaimed, even though the technique that was calculated may be entirely correct.

A second, related trap is treating the two techniques as interchangeable shortcuts for the same number. They are not: a forward contract depends on the quoted forward rate, while a money market hedge depends on interest rate differentials between the two currencies, broadly reflecting interest rate parity. Where the data given in the question makes one technique clearly cheaper, showing both workings is what demonstrates that understanding to the marker — a bare forward contract calculation does not.

Building this into your exam approach

When a question gives you both a forward rate and a set of interest rates, treat that as an instruction: calculate the forward contract outcome, calculate the money market hedge outcome, lay them side by side, and recommend the cheaper or more favourable one with a short explanation of the difference. This structure also transfers directly to other AFM foreign exchange risk questions, including those that combine hedging with valuation techniques such as adjusted present value (APV), where the same discipline of showing full workings for every relevant technique, rather than the one you find quickest, is what separates a pass-mark answer from a strong one. For the full syllabus context on where foreign exchange risk sits within the wider paper, the ACCA Advanced Financial Management hub is the best starting point.

The takeaway

Forward contracts and money market hedges are not competing shortcuts to memorise separately — they are two calculations the exam expects you to run every time a foreign exchange risk question appears, so that the choice between them is evidenced rather than assumed. Build the habit of always doing both, and the comparison and recommendation marks stop being the ones you lose.
