Foreign exchange risk

Definition

Foreign exchange risk arises when a business has revenues, costs or debts in a currency other than sterling, so exchange-rate movements between agreeing and settling a transaction alter its value.

In plain terms

Agree a price in dollars today, get paid in three months, and a shifting rate can quietly eat your profit — or hand you a windfall. Either way, it is uncertainty.

Why it matters for your company

Importers and exporters can hedge FX risk with forward contracts and matched-currency finance, protecting margins. It pairs with trade finance. See FX management in your planning.

In practice

Picture a UK limited company that buys components from an overseas supplier and invoices its own customers in sterling. The purchase order is agreed at one rate, but payment falls due weeks later once goods have shipped and been checked in. Between those two points, the exchange rate can drift in either direction, so the sterling cost of the same invoice is not fixed until the payment actually clears.

The same dynamic runs the other way for a company invoicing overseas customers in a foreign currency: the value that eventually lands in the business's sterling bank account depends on where the rate sits on the day it converts. Because purchasing, sales and finance teams often each see only their own slice of this exposure, the full picture of how much foreign-currency exposure the company is carrying at any one time is easy to lose track of unless someone is pulling it together centrally.

How lenders read it

When a lender is assessing a company with material overseas trade, unhedged FX exposure is treated as a source of variability in future cash flow rather than as a defect in the business itself. A company that has thought about how it manages this exposure, even informally, through pricing decisions or supplier terms, tends to present a clearer picture of near-term cash flow than one that has not considered it at all.

A common pitfall is treating FX risk as a finance-department afterthought rather than a trading decision taken at the point a deal is struck. By the time an invoice is raised or an order is placed, much of the exposure is already locked in; reviewing currency exposure as part of the same conversation as pricing and contract terms, referenced alongside trade finance arrangements, keeps it visible rather than something only spotted at month-end.
