What it means
Currencies move constantly, and a business that agrees a price today but receives payment in ninety days is exposed to whatever happens in between. If the foreign currency weakens, the same amount of foreign money converts into fewer home currency dollars, and the margin the sales team calculated simply evaporates.
Nothing operational has gone wrong, yet the profit is smaller. The exposure comes in three recognised forms.
Transaction risk affects specific invoices and payments already committed, translation risk affects the reported value of foreign subsidiaries when their accounts are converted for the group, and economic risk affects long-term competitiveness when a persistently strong home currency makes exports expensive. The first is the most immediate, the third the most strategic.
The risk matters most where margins are thin, because a 5% currency move can wipe out a 4% net margin entirely. It also matters where the timing gap is long, such as construction contracts, capital equipment orders or annual supply agreements.
Businesses that price in one currency and pay costs in another are structurally exposed even when every individual deal looks profitable. Companies manage the risk in several ways, starting with the simplest.
Natural hedging matches revenue and costs in the same currency, so a firm selling in euros tries to buy components in euros too. Where that is impossible, treasurers use forward contracts to fix a rate today for a future date, or options that set a worst-case rate while allowing some benefit if the currency moves favourably.
Two points of nuance are worth holding onto. Hedging removes uncertainty rather than guaranteeing the best outcome, so a hedged company will sometimes look worse than an unhedged one after the fact.
And translation risk, while it dents reported results, involves no actual cash movement, which is why many groups hedge transaction exposure carefully and leave translation exposure alone.
In practice
Real-world examples.
Example
A British furniture importer buys 60% of its stock from suppliers invoicing in dollars while selling entirely in pounds. A 9% fall in the pound over one quarter raises landed costs by roughly $420,000 and forces a mid-season price increase that dents volumes.
Example
A global consultancy reports in dollars but earns a third of its fees in Japanese yen. A weakening yen reduces reported group revenue by 4% even though the Japanese business grew in local terms and collected every invoice on time.
Example
A mining company borrows in dollars because rates are lower but earns revenue in Australian dollars. When the Australian dollar falls, the debt becomes far more expensive to service in local earnings terms and a covenant test is nearly breached.
Think of it
“Exchange rate risk is the danger that currency movements will hurt your international business values.
Formula
Calculation
Home currency value = foreign currency amount x exchange rate
Gain or loss = foreign currency amount x (rate at settlement - rate when booked)
A machinery exporter based in the United States sells equipment to a European buyer for 500,000 euros, payable in 90 days. On the day the contract is signed, the rate is 1.10 dollars per euro.
Expected receipt = 500,000 x 1.10 = $550,000
Ninety days later the euro has weakened to 1.04 dollars per euro.
Actual receipt = 500,000 x 1.04 = $520,000
Loss = 500,000 x (1.04 - 1.10) = 500,000 x -0.06 = -$30,000
The exporter receives $30,000 less than planned, which on a contract with an expected profit of $70,000 removes 43% of the margin. Had the treasurer taken out a forward contract at signing to sell 500,000 euros at 1.095, the receipt would have been fixed at 500,000 x 1.095 = $547,500 regardless of what the market did, at the cost of giving up any gain had the euro strengthened.Case study
Seen in the real world.
Aldervale Instruments is a fictional maker of laboratory equipment, presented purely as an illustrative example. It reported in dollars, sold roughly 40% of its output into Europe and priced every export order in euros to keep customers happy.
For three years the euro traded in a narrow band and nobody in the finance team gave the exposure much thought. Then the euro fell 11% over five months while the company was carrying 4,200,000 euros of unhedged orders with delivery dates spread over the following two quarters, producing an unbudgeted loss of about $460,000 and turning a forecast profit into a small loss.
The treasurer introduced a policy of hedging 80% of confirmed euro orders with forward contracts at the point of order acceptance, leaving 20% open. The company also began sourcing more components from European suppliers, creating a natural offset of roughly 1,500,000 euros a year. Currency results have since moved within a range the board considers acceptable, and quoted margins now survive contact with the settlement date.
Watch out
Common mistakes.
- Assuming a business has no currency exposure because it invoices only in its home currency, when suppliers, competitors or customers priced abroad still transmit the risk.
- Hedging only after a currency has already moved sharply, which locks in the damage rather than preventing it.
- Judging a hedging policy a failure because the currency happened to move favourably, when the purpose was to remove uncertainty rather than to predict the market.
Questions
People also ask.
What is the difference between transaction and translation risk?
Transaction risk affects real cash on specific deals, while translation risk only changes the reported value of foreign operations when their accounts are converted into the group's currency.
Should a small business hedge?
If foreign currency flows are large relative to profit, then yes, and simple forward contracts through a bank are usually enough; if the exposure is trivial, the cost and effort may not be justified.
Does invoicing in your home currency remove the risk?
It transfers the currency risk to the customer, which often shows up instead as pricing pressure or lost orders, so the exposure changes form rather than disappearing.
