How Do Exchange Rates Affect Businesses? A Complete Guide for 2026
You approve a supplier invoice on Monday and pay it on Friday. In between, the pound slips and the bill is now bigger than the one you signed off. Nobody renegotiated anything, yet your margin has taken a knock. So, how do exchange rates affect businesses? They change what you pay, what you earn and what your overseas assets are worth. This guide covers how exchange rates work, where the risk sits and what UK firms can do about it, with real figures and simple examples.
How Do Exchange Rates Affect Businesses? The Short Answer
Exchange rates change the sterling value of every foreign payment you make or receive. That moves import costs, export income, profit margins, cash flow and the value of overseas earnings, sometimes within days.
- Costs: imports get dearer when the pound falls
- Pricing: UK exports look cheaper to overseas buyers
- Profit: margins shift between quote and payment
- Cash flow: payments become harder to forecast
- Investment: expanding abroad costs more or less depending on the rate
The scale of UK trade shows why this matters. In the 12 months to January 2026, the UK exported £931.7 billion and imported £971.7 billion of goods and services, according to the ONS (opens in a new tab). Much of that is paid for in foreign currency, so rate moves reach a lot of balance sheets.
What Do Exchange Rates Mean, and How Is an Exchange Rate Determined?
An exchange rate is the price of one currency in another. It is determined by supply and demand in the forex market, which moves with interest rates, inflation, economic data, trade flows and sentiment.
What affects exchange rates most:
- Interest rates: higher rates tend to attract investors and lift a currency
- Inflation: persistently high inflation can weaken it
- Economic data: growth, jobs and trade figures change expectations
- Politics: budgets, elections and trade deals can cause sudden swings
Rates are quoted in pairs. GBP/USD at 1.25 means one pound buys 1.25 dollars. The spot rate is today’s price, while a forward rate is one agreed today for a future date.
Sentiment can move fast. In September 2022 sterling dropped to an all-time low of about $1.03, roughly 25% below its October 2021 high. That was within a year, and it followed a mini-budget that unsettled markets.
Key Effects of Exchange Rates on Businesses
The effects of exchange rates on businesses show up in import costs, export pricing, margins, cash flow and foreign debt. How much you feel depends on how much you trade abroad and how long payments take.
- Import costs: a weaker pound raises supplier bills
- Export competitiveness: a weaker pound makes UK goods cheaper abroad
- Profit margins: fixed prices and moving rates squeeze forecasts
- Cash flow: the amount you pay or receive changes before the money moves
- Foreign revenue and assets: overseas earnings are converted back to sterling at the going rate
- Foreign currency debt: repayments rise if the pound weakens
A stronger pound is not automatically good or bad. It cuts import costs but can make exports harder to sell. Every business has its own comfort zone, and finding yours is the first job.
Types of Exchange Rate Risk
Exchange rate risk is the chance that currency moves cut your profit or value. It comes in three main types: transaction, translation and economic exposure, and most businesses carry more than one.
- Transaction exposure: the rate moves between invoice date and payment date
- Translation exposure: overseas accounts are converted into pounds for reporting
- Economic exposure: long-term currency shifts change your competitive position
UK importers and exporters trading in euros and dollars feel transaction exposure first, because it hits cash directly. Translation and economic exposure matter more for groups with overseas subsidiaries or customers.
Who Is Affected Most? Real-World Examples
Importers, exporters, SMEs without a treasury team and firms billing overseas clients feel exchange rate risk most. Since Brexit, trade in euros and dollars has become routine for many UK businesses.
- Import example: a UK retailer owes $125,000. When sterling was near $1.37, that cost about £91,000. At the 2022 low near $1.03, the same invoice cost about £121,000, roughly £30,000 more for identical goods.
- Export example (illustrative): a UK manufacturer invoices €100,000. At 1.15 euros per pound that is about £86,957. If the pound weakens to 1.10, the same invoice is worth about £90,909.
- Small firms: with no treasury team, the risk often goes unmanaged until it shows up in the accounts.
| GBP/USD rate | Cost in sterling |
|---|---|
| Near 1.37 | About £91,000 |
| Near 1.03 (2022 low) | About £121,000, roughly £30,000 more |
| Euros per pound | Value in sterling |
|---|---|
| 1.15 | About £86,957 |
| 1.10 | About £90,909 |
The same market move can help one business and hurt another. Your own exposure matters more than the headline rate.
How Businesses Manage Exchange Rate Risk
Businesses manage exchange rate risk by measuring their exposure, then using tools such as forward contracts, options and multi-currency accounts to fix or limit the rate they pay. A written FX policy keeps decisions consistent.
- Forward contracts: lock a rate for a future date, giving certainty but no upside
- Currency options: set a worst-case rate and keep the upside, for an upfront premium
- Natural hedging: match foreign income against foreign costs
- Multi-currency accounts: hold currency until you need it
- Pricing: invoice in sterling or add price-adjustment clauses
- Treasury technology: one live view of exposures and hedges
No single tool wins every time. Forwards suit predictable payments and options suit uncertain ones. Most firms use a mix and review it every few months. Interest rates add another moving part. At its September 2026 meeting the Bank of England (opens in a new tab) held the Bank Rate at 3.75%, but three of the nine members voted for a rise, with inflation at 3.1% in August. A split vote like that is exactly the kind of news that can move sterling.

Frequently Asked Questions
How do exchange rates affect small businesses?
Small businesses feel it through supplier bills, overseas sales and thin margins. A small rate move can wipe out the profit on a contract, and without a treasury team the risk often goes unnoticed until the invoice is due.
Does a weaker pound help or hurt UK businesses?
It depends on your trade. A weaker pound raises the cost of imported goods and materials, but it makes UK exports cheaper for overseas buyers and lifts the sterling value of foreign earnings.
How does the interest rate affect the exchange rate?
Higher interest rates usually attract foreign investors looking for better returns. That raises demand for the currency and can strengthen it. Markets also react to expected rate changes, so the move often starts before the decision.
Can an exchange rate move wipe out a small profit margin?
Yes. If your margin is 5% and the pound falls 5% against your supplier’s currency before you pay, the whole margin on that order can vanish. Hedging takes that surprise out of the equation.
What is a forward contract?
A forward contract lets you agree an exchange rate today for a payment on a future date. You know exactly what the payment will cost, but you cannot benefit if the market moves in your favour.
