A profitable export order can be turned into a disappointing one without a single fault in the product, delivery or customer relationship. The damage may be done simply because sterling moves between accepting the order and receiving the money. Currency forward buying and hedging are practical ways of preventing an exchange-rate movement from deciding whether a carefully negotiated transaction makes money.
For businesses trading overseas, currency is not a technical footnote for the accounts department. It is part of the commercial risk. Anyone who has spent time winning orders in distant markets knows how much work can sit behind a quotation: visits, agents, samples, freight discussions, specifications, credit checks and lengthy negotiation. It is poor business to leave the final margin exposed to a market movement over which neither buyer nor seller has any control.
