Summary Table: Transaction Exposure & Hedging Tools

What is Transaction Exposure? The risk from exchange rate fluctuations after entering a foreign-currency obligation (payable/receivable).
Who is affected? The party that must settle in foreign currency — typically the importer (payable) or exporter (receivable).
Example A U.S. firm might need to pay R$10,000 in 30 days. If the Brazilian real appreciates, the USD cost rises. A U.S. exporter that will receive pounds later faces the opposite concern.
Types of FX exposure
  • Transaction: short-term contract risk
  • Operating (economic): long-run cash flow/competitiveness
  • Translation: accounting revaluation of balance-sheet items

Hedging strategies overview with simple graphs

Forward contract

Best use: importer or exporter that wants a known result today
future spot rate USD result
Picture: flat line = locked result. No upside, no downside.
Why it is sure: you lock the forward rate today, so the future spot rate no longer changes the final dollar result.

Money market hedge

Best use: importer or exporter that wants a known result and can use borrowing/deposit steps
future spot rate USD result
Picture: also flat = known result, because it is a synthetic forward.
Why it is sure: you use spot today + interest rates today. Importer: buy and invest foreign currency now. Exporter: borrow foreign currency now, convert now, and invest dollars now.

Call option for an importer

Best use: payable exposure when the firm wants protection but still wants upside
K future spot rate USD cost
Picture: line rises with spot at first, then becomes flat at the cap.
Not sure yet: the final dollar cost depends on the future spot rate. If the foreign currency becomes expensive, you exercise. If it becomes cheap, you let the option expire and buy at spot.

Put option for an exporter

Best use: receivable exposure when the firm wants a floor but still wants upside
K future spot rate USD revenue
Picture: flat floor first, then revenue rises when the future spot rate rises.
Not sure yet: the final dollar revenue depends on the future spot rate. If the foreign currency weakens, you exercise. If it strengthens, you let the put expire and sell at the better spot rate.
Rule of thumb: Importer (payable) fears foreign currency appreciation → likes buying FC forward or buying a call. Exporter (receivable) fears foreign currency depreciation → likes selling FC forward or buying a put.
Importing Payable

In-class exercise: Importing (currency payable)

ICE 1: Brazil example (R$ payable)

You must pay R$10,000 in 30 days. Current spot: 1 real = $0.20 (expected cost ≈ $2,000). If the real appreciates to $0.21, the USD cost becomes $2,100. That extra $100 is the transaction exposure problem.

Student tasks (short answers)
  1. If you do nothing and the real strengthens: USD cost rises; you pay more dollars for the same R$ amount.
  2. Forward hedge: buy reais forward for 30 days → locks the USD cost today; no uncertainty.
  3. Call option hedge: buy a real call → if the real appreciates above the strike, exercise; if the real depreciates, let it expire and buy reais cheaper at spot.
  4. Money market hedge: buy reais “today” by borrowing USD, converting to reais at spot, and investing reais so they grow to the needed payable by day 30.
Why would an importer hedge this payable?

The importer is worried about foreign currency appreciation. The bill is fixed in reais, but the dollar cost is not fixed. If the real rises, profit margin falls. A hedge turns an uncertain future dollar cost into either:

  • a known cost today with a forward or money market hedge, or
  • a cost ceiling with a call option.
Simple memory line: Importer = must buy foreign currency later = fears that foreign currency gets more expensive.

Pay R$ / £ / € laterForeign currency appreciatesBuy FC forward or buy FC call or money market hedge
Pay later but want upsideStill fear appreciationCall option gives a cap with upside if FC depreciates
FC = foreign currency.

Money market hedge: slow story version

Goal: make sure you already have enough reais invested today so that the investment grows into the exact payable later.

Today
Figure out how many reais you must deposit today so that the account grows to R$10,000 by the due date.
→
Today
Borrow that many USD, then use spot to buy the reais now.
→
Between now and maturity
Leave the reais on deposit so the real deposit grows.
→
At maturity
The reais deposit becomes the exact amount needed to pay the invoice. Your USD loan repayment is known.
  • If you are worried about cost certainty, money market hedge is strong because the final dollar cost is known today.
  • If your bank loan/deposit rates are favorable, this can beat the forward rate.
  • If students ask “why does it work?” the answer is: you removed FX risk by using spot + interest rates today instead of waiting for the future spot rate.

Call option hedge: slow story version

Goal: pay a premium now so you are protected if the real gets expensive, but still keep the benefit if the real gets cheaper.

Today
Buy a call option on reais and pay the option premium.
→
At maturity
Look at the future spot rate and compare it with the strike price.
→
If spot > strike
Exercise the call. Buy reais at the strike instead of the more expensive market price.
→
If spot ≤ strike
Let the call expire. Buy reais in the cheaper spot market. Your “insurance cost” is the premium.
  • If the bad thing you fear happens — the real appreciates — the call protects you.
  • If the good thing happens — the real depreciates — you can ignore the option and buy cheaper at spot.
  • Why choose it? Firms often prefer a call when they want protection but do not want to give up favorable exchange-rate moves.
Exporting Receivable

In-class exercise: Exporting (currency receivable)

ICE 2: UK example (£ receivable)

You will receive £10,000 in 30 days. Current spot: 1 pound = $1.25 (expected $12,500). If the pound weakens to $1.18, you only receive $11,800. That drop of $700 is the transaction exposure problem.

Student tasks (short answers)
  1. If you do nothing and the pound weakens: the USD value of your receivable falls.
  2. Forward hedge: sell pounds forward → locks USD revenue today.
  3. Put option hedge: buy a pound put → if the pound depreciates below the strike, exercise; if the pound appreciates, let it expire and sell at the better spot price.
  4. Money market hedge: borrow pounds today against the receivable, convert to USD now, and invest USD so the final dollar value is known today.
Why would an exporter hedge this receivable?

The exporter is worried about foreign currency depreciation. The sale amount in pounds is fixed, but the dollar value of that sale can fall before the money arrives. A hedge turns an uncertain future dollar value into either:

  • a known revenue today with a forward or money market hedge, or
  • a revenue floor with a put option.
Simple memory line: Exporter = will receive foreign currency later = fears that foreign currency gets cheaper.

Exporter hedging map (what to do)

If you will RECEIVE foreign currency…What you fearTypical hedge
Receive £ / R$ / € laterForeign currency depreciatesSell FC forward or buy FC put or money market hedge
Receive later but want upsideStill fear depreciationPut option sets a floor with upside if FC appreciates

Money market hedge: slow story version

Goal: turn the future pound receivable into dollars today by borrowing pounds now and using the later receivable to repay that pound loan.

Today
Borrow the present value of the future pound receivable.
→
Today
Convert those borrowed pounds into USD at today’s spot rate.
→
Between now and maturity
Invest the USD so the dollar value grows predictably.
→
At maturity
Use the actual pound receivable to repay the pound loan. The dollar proceeds were effectively locked in earlier.
  • If you want certainty today, this is a strong hedge because the future dollar value is already engineered using today’s rates.
  • If forward pricing is not available or not attractive, the money market hedge is the classic backup.
  • Why does it work? The future FX uncertainty is replaced by known borrowing and investing transactions today.

Put option hedge: slow story version

Goal: pay a premium now so you are protected if the pound falls, but still keep upside if the pound rises.

Today
Buy a put option on pounds and pay the premium.
→
At maturity
Look at the future spot rate and compare it with the strike price.
→
If spot < strike
Exercise the put. Sell pounds at the strike instead of the weaker market price.
→
If spot ≥ strike
Let the put expire. Sell pounds at the better spot rate. Your insurance cost is the premium.
  • If the bad thing you fear happens — the pound depreciates — the put protects your revenue floor.
  • If the good thing happens — the pound appreciates — you keep the upside, minus the premium.
  • Why choose it? Firms often prefer a put when they want downside protection but still want to benefit from a stronger foreign currency.
Calculator Forward • MM • Options

Hedge calculators (plug-and-play)

Convention here uses exchange rate quoted as USD per 1 unit of foreign currency (e.g., $ / £, $ / €, $ / SF). For money market hedges, be sure the interest rates match the horizon (e.g., 6-month rate for 6 months).

Importer (payable): given FC payable, compute hedged USD cost

Loading default ICE 1 example…
Formulas used
Forward cost = FC × F
Money market (payable):
Deposit today = FC / (1+i_f)^T
USD today needed = (FC/(1+i_f)^T) × S
USD cost at T = USD_today × (1+i_US)^T
Call “cap” (scenario):
If ST > K: exercise, USD cost = FC × (K + p)
If ST ≤ K: let expire, USD cost = FC × ST + FC × p
Note: option premium is paid up front in practice; here we keep it in per-unit terms for clarity.

Exporter (receivable): given FC receivable, compute hedged USD revenue

Loading default ICE 2 example…
Formulas used
Forward revenue = FC × F
Money market (receivable):
Borrow today = FC / (1+i_f)^T
Convert to USD now = Borrow × S
Invest USD at i_US: USD_T = USD_now × (1+i_US)^T
Repay foreign loan at T using receivable (they match by construction).
Put “floor” (scenario):
If ST < K: exercise, USD revenue = FC × (K − p)
If ST ≥ K: let expire, USD revenue = FC × ST − FC × p
Options: premium reduces net proceeds. If currency moves favorably, you keep upside minus premium.
Decision guide Winner shines

Which approach looks better?

Forward and money market are known today, so their results are sure. Call/put options are different: the winner depends on the future spot rate at expiration.
Real case guide How firms actually choose

Why choose forward, money market, or options in real life?

Choice Why firms like it Main drawback Typical real-world fit
Forward
  • Simple and easy to explain to management.
  • Known result today.
  • Usually no option premium up front.
  • No upside from favorable FX moves.
  • Usually requires a bank or FX counterparty relationship.
  • May involve credit limits, collateral, or line usage.
 Best for a known amount and known date, especially larger invoices where the firm mainly wants certainty.
Money market hedge
  • Also gives a known result today.
  • Useful when forward pricing is unavailable or less attractive.
  • Good teaching tool because students can see how spot and rates create a synthetic forward.
  • More steps: borrow, convert, invest, repay.
  • Needs access to borrowing and deposit markets.
  • Operationally more work than a plain forward.
 Best when the firm has good credit lines and treasury staff, or when it wants to compare bank forward pricing with a synthetic hedge.
Call / Put option
  • Protects against the bad outcome but keeps upside.
  • Good when the amount or timing is less certain.
  • Good when management wants insurance rather than a full lock.
  • Premium cost is real and visible.
  • Small firms may find pricing expensive relative to deal size.
  • OTC option markets can be less flexible for very small transactions.
 Best when the firm wants downside protection with upside left open, especially when the firm has a view on FX or wants flexibility.

What treasury teams often ask before choosing

  • Is the amount certain and the payment date fixed? Forward often becomes the first choice.
  • Is the firm comfortable giving up upside? If yes, forward or money market is common. If no, option becomes more attractive.
  • Is the deal large enough to justify dealer quotes and documentation? Larger deals are more likely to use forwards or OTC options.
  • Does the firm already have a bank treasury relationship? That makes forwards and options easier to arrange.
  • Does the firm have borrowing capacity? That matters for money market hedges.
Where do firms usually get these hedges? Most firms do not “go shopping” for hedges casually. They usually work through a commercial bank treasury / FX desk, a corporate bank relationship manager, or an approved FX dealer. Forwards are usually OTC contracts with a bank or dealer. OTC options are also often arranged through a bank or dealer and may require minimum size, documentation, or credit approval. Very small firms may use simpler bank products or sometimes avoid options because the premium and setup can feel expensive relative to the invoice size.
Very real case thinking: a firm importing inventory with thin margins may choose a forward because management mainly wants cost certainty. A firm with uncertain order volume may prefer a call option because it wants protection without fully locking in. A sophisticated treasury team may compare the bank’s forward quote with a money market hedge to see which locked result is better.
Homework Due with final

Homework (Module 14)

1) Real case: U.S. importer buying a UK machine — £10 million payable in 1 year

A U.S. manufacturing company agrees today to buy a specialized machine from a UK supplier. The contract requires the U.S. firm to pay £10,000,000 in 1 year. The CFO worries that the British pound may appreciate, which would make the dollar cost higher.

Use these data: S = $1.50/£, F = $1.46/£, iUS = 6.10%, iUK = 9.00%, and a call option on £ with K = $1.46/£ and premium $0.03/£.

Compute the dollar cost under: (a) a forward hedge, (b) a money market hedge, and (c) a call option hedge. Then explain which approach gives the firm a sure dollar cost today and which approach keeps some upside if the pound later becomes cheaper.

2) Real case: U.S. exporter selling to a UK customer — £10 million receivable in 1 year

A U.S. company sells equipment to a UK customer and will receive £10,000,000 in 1 year. The CFO worries that the British pound may depreciate, which would reduce the dollar value of the receivable.

Use these data: S = $1.50/£, F = $1.46/£, iUS = 6.10%, iUK = 9.00%, and a put option on £ with K = $1.46/£ and premium $0.03/£.

Compute the dollar revenue under: (a) a forward hedge, (b) a money market hedge, and (c) a put option hedge. Then explain which approach gives the firm a sure dollar revenue today and which approach still allows upside if the pound later becomes stronger.
