Managing Transaction Exposure
Week 5 of UNSW FINS3616 defines transaction exposure on committed foreign-currency receivables and payables (Shapiro Ch 9) and compares the hedging alternatives — the forward hedge, the money-market hedge, and the option hedge — computing the certain or expected home-currency outcome of each. The classic worked problem is to hedge a payable two ways and show that covered interest rate parity makes the forward and money-market hedges equivalent. Exposure management carries increased weight on the 40% final exam.
What this chapter covers
- 01Transaction exposure: the home-currency value of a known, contractual foreign-currency cash flow changing between contract and settlement
- 02Forward/futures hedge: lock the rate today for the known amount and date
- 03Money-market hedge: borrow/lend in the two currencies to synthesise a locked rate; for a payable, invest the PV of the foreign amount now
- 04Option hedge: cap or floor the outcome for a premium — best for contingent exposure
- 05Comparing hedges: certain vs expected home-currency outcome; covered IRP makes forward and money-market hedges equivalent
- 06Internal/operational techniques: currency-of-invoicing choice, leading and lagging, bilateral and multilateral netting, exposure netting, risk-sharing
- 07The true cost of a forward hedge = forward rate minus the EXPECTED future spot, not the forward premium/discount
- 08Choosing a hedge: cost/benefit trade-offs and the exposure's certainty
Money-market vs forward hedge of a foreign-currency payable
- +1Money-market hedge for a payable: lock the euros now by investing their present value at the euro rate. Amount of euros to invest today = €1,000,000 / (1 + r_f) = 1,000,000 / 1.03 = €970,873.79 (which grows to exactly €1,000,000 in a year).
- +1Buy those euros at the spot 1.1000: cost today = €970,873.79 × 1.1000 = $1,067,961.17 (funded at the US 5% rate, or the opportunity cost of cash).
- +1Express the locked cost at maturity by carrying it forward at the US rate: $1,067,961.17 × 1.05 = $1,121,359. That is the certain home-currency cost under the money-market hedge.
- +1Forward hedge cross-check: the covered-IRP forward is f = 1.1000 × (1.05/1.03) = 1.12136 USD/EUR, so the forward-hedged cost = €1,000,000 × 1.12136 = $1,121,359 — identical, because covered interest rate parity makes the money-market and forward hedges equivalent.
Key terms
- Transaction exposure
- The risk that the home-currency value of a known, contractual foreign-currency cash flow (a receivable or payable) changes with the exchange rate between the contract date and the settlement date.
- Forward hedge
- Locking the exchange rate today with a forward contract for the known foreign-currency amount and date, converting an uncertain home-currency outcome into a certain one.
- Money-market hedge
- Synthesising a locked rate by borrowing and lending in the two currencies. For a payable, invest the present value of the foreign amount now so it grows to the amount owed; for a receivable, borrow the present value now and repay with the incoming funds.
- Netting
- Reducing intra-firm FX transactions by settling only net positions — bilateral (between two affiliates) or multilateral (through a netting centre) — which cuts transaction costs and exposure.
- Leading and lagging
- Accelerating (leading) or delaying (lagging) the settlement of foreign-currency payables and receivables to manage exposure — for example paying early in a currency expected to appreciate.
- True cost of a forward hedge
- Not the forward premium or discount, but the difference between the forward rate and the EXPECTED future spot rate. The premium/discount reflects the interest differential; the expected cost reflects how the forward compares to where the spot is actually expected to be.
Managing Transaction Exposure FAQ
For a payable, do I invest or borrow in the money-market hedge?
You invest. A payable means you will need foreign currency later, so you buy just enough foreign currency today and invest it at the foreign interest rate so it grows to exactly the amount owed at settlement — that locks the cost now. For a receivable it is the mirror image: you will receive foreign currency later, so you borrow its present value today, convert to home currency now, and repay the foreign-currency loan with the incoming funds. Mixing up invest-versus-borrow is the most common money-market-hedge error.
Why do the forward hedge and the money-market hedge give the same cost?
Because covered interest rate parity ties the forward rate to the interest differential: f = e₀(1+r_h)/(1+r_f). The money-market hedge is built directly from those same two interest rates and the spot, so when you carry its cost to maturity you get exactly the forward-hedged amount. If they did not match, a covered-interest-arbitrage profit would exist. In practice small differences arise from bid-ask spreads and different borrowing versus lending rates, but the textbook result is that they are equivalent.
What is the real cost of hedging with a forward?
It is not the forward premium or discount — that just reflects the interest differential and is baked into any covered hedge. The economically meaningful expected cost is the difference between the forward rate you lock and the rate the spot is actually expected to be at settlement. If the forward is above the expected future spot, hedging a payable looks expensive in expectation (you could have waited); if below, it looks cheap. Hedging still removes risk, which can be worth paying for regardless.
Can AI help me with transaction-exposure hedging in FINS3616?
Yes. Sia is an AI tutor built to mirror how FINS3616 is taught and assessed at UNSW Sydney: it can walk you through a forward, money-market and option hedge of the same exposure, check whether you should invest or borrow, and compare the certain versus expected outcomes step by step. It checks your reasoning but does not do graded assessment, and UNSW academic-integrity rules apply — exposure management carries extra weight on the 40% final, so use it to rehearse.
Exam move
The money-market hedge is where marks are won and lost, so drill the direction rule first: payable → invest the PV of the foreign currency; receivable → borrow the PV of the foreign currency. Then practise hedging one exposure three ways — forward, money-market, option — and comparing outcomes, and always show that the forward and money-market hedges match because of covered interest rate parity (a favourite exam point). Keep straight the difference between the forward premium/discount and the true expected cost of a forward hedge, because that distinction is a reliable short-answer trap. Learn the internal techniques — invoicing currency, leading and lagging, bilateral and multilateral netting, exposure netting, risk-sharing — well enough to recommend one in a scenario question. Because Week 5 exposure management is flagged for increased weight on the cumulative 40% final exam, rehearse both the calculations and the scenario reasoning on the recorded tutorial questions under time. When invest-versus-borrow or a matching check won't click, ask Sia to re-run the hedge on fresh numbers and mark your working.
