What it means
Whenever a company pays an overseas supplier, receives a customer payment in another currency or invests abroad, a currency exchange is involved. The sum of all those deals, plus trading by banks, funds and governments, forms the international currency market, which is among the largest financial markets in the world.
Prices are quoted as pairs, such as how many units of one currency are needed to buy one unit of another. The rate moves constantly in response to interest rates, inflation, trade flows, economic news and the expectations of traders.
Businesses use the market in several ways. They convert currencies for everyday payments (the spot market), lock in a future rate using forward contracts, and buy options that give protection while keeping the chance to benefit from favourable moves.
Banks usually quote two prices for a pair, the rate at which they will buy and the rate at which they will sell, and the difference is the spread. Small businesses typically pay wider spreads than large corporations, because their trades are smaller and less competitive.
Governments and central banks also take part. They may intervene to steady their currency, set interest rates that attract or repel capital, or hold foreign reserves for emergencies.
A rate shown on a news site is a wholesale reference, and the rate a small business actually receives from its bank or payment provider will usually include a margin on top. The nuance for managers is the distinction between transaction risk, translation risk and economic risk.
A single swing in exchange rates can change the dollar value of a receivable, the reported value of a foreign subsidiary and the competitiveness of a company's products abroad, and each needs a different response.
In practice
Real-world examples.
Example
A US importer buys machinery from a German supplier priced in euros. It uses the spot market to buy euros on the payment date. Its treasury team also keeps an eye on the rate in the weeks beforehand to decide when to convert.
Example
A Singapore-based exporter sells goods to customers in several countries and invoices in dollars. Its finance team uses forward contracts to lock in the rate for known invoices. This protects its margin from sudden movements. It reviews the hedge ratio each quarter as its sales forecasts change.
Example
A global asset manager holds shares in Japanese companies. It also hedges the yen exposure with currency forwards, because it wants to earn the return on the shares, not the swings in the yen. The cost of the hedge is built into its performance reporting, so clients can see what protection costs.
Formula
Calculation
Dollar value of a foreign amount = Foreign amount x Exchange rate (dollars per unit of foreign currency)
Suppose a US exporter will receive 400,000 euros in three months. At today's rate of $1.10 per euro, the receivable is worth 400,000 x 1.10 = $440,000. If the rate falls to $1.05 per euro by the payment date, it is worth 400,000 x 1.05 = $420,000. The exporter loses 440,000 - 420,000 = $20,000, which is about 4.5% of the original value. A forward contract fixing the rate at $1.10 would have removed that loss, though it would also have removed any gain.Case study
Seen in the real world.
This is an illustrative story about a fictional company, Silverline Textiles, which buys cotton in one currency, manufactures in a second and sells in a third. Its finance team had never hedged, and an unfavourable currency move in a single quarter wiped out most of its profit on a large order.
The CFO set up a simple policy. Confirmed orders would be hedged with forward contracts covering 80% of the expected foreign currency amount, while uncertain forecasts would be left unhedged until the orders firmed up.
In the next year, rates moved against Silverline again, but the hedges offset most of the loss. The illustrative lesson is that managing currency exposure is not about predicting rates, it is about protecting margins from surprises.
Watch out
Common mistakes.
- Assuming the market closes at night. It runs continuously through the week as trading passes between major financial centres.
- Comparing only the headline rate. Fees, spreads and settlement timing all affect the real cost of an exchange.
- Hedging the whole forecast regardless of certainty. Over-hedging uncertain sales can create losses if the sales never happen.
