Cash flow, staffing, marketing – the standard business plan covers them all. Currency exposure almost never appears, and for any firm that buys or sells abroad, that omission gets expensive.
Read a hundred small business plans and you will find the same sections in roughly the same order: the market, the model, the projections, the risks. The risk section will mention competitors, key staff leaving, maybe a recession. What it almost never mentions is the exchange rate – despite the fact that for an importer, an exporter, or anyone paying overseas suppliers or contractors, a ten percent currency move can do more damage than any competitor.
This is not a hypothetical. Sterling has moved more than ten percent against the dollar in multiple twelve-month windows over the past decade. A business plan whose margins survive at 1.30 and fail at 1.17 does not have a margin problem. It has an unexamined assumption problem.
Where currency risk hides in an ordinary business
The obvious cases are import costs and export revenue. The less obvious ones are where plans actually get caught out: software subscriptions billed in dollars, freelancers invoicing in euros, a key raw material priced globally in dollars even when bought from a UK distributor, and marketplace fees settled in foreign currency. Individually each looks small. Added up, plenty of nominally domestic firms have twenty or thirty percent of their cost base effectively denominated in someone else’s currency.
The planning fix is straightforward and costs nothing: total every line of the plan that is paid or received in a foreign currency, and rerun the projections at rates ten percent worse. If the plan still works, note that and move on. If it does not, you have found something worth designing around before it happens rather than after.
Hedging, and the line between managing risk and taking it
For firms with real exposure, the practical tools are unglamorous: forward contracts that lock a rate for a future payment, multi-currency accounts that let you hold and time conversions, and simply invoicing customers in sterling where the relationship allows it. A conversation with your bank or a payments provider covers most of it, and for many small firms the multi-currency account alone removes the worst of the friction.
There is a boundary worth marking clearly, though, because it gets crossed by accident. Managing currency exposure is business administration; trading currency for profit is speculation, and it is a different activity with a different risk profile entirely. Business owners who get interested in the currency markets through their own exposure sometimes graduate to trading them, and anyone tempted should first read the UK trading statistics compiled by The Investors Centre from FCA filings and the brokers’ own disclosures – the loss rates among retail currency traders are published, regulated numbers, and they are sobering.
If, having seen those numbers, currency trading is still of interest – as a deliberate, ring-fenced activity rather than a sideline of the business – then the choice of provider matters more than beginners assume. The Investors Centre’s comparison of the best forex brokers in the UK is built by funding live accounts with the firm’s own money rather than working from published fee schedules, which is where the real differences in spreads, conversion costs and withdrawal behaviour show up. Whatever you choose, the golden rule from the planning side is the same one that applies to every risk in the document: size it so that being wrong changes nothing about the business.
The one-paragraph version for your plan
Add a short section under risks: which lines of the plan are exposed to exchange rates, what the projections look like at rates ten percent worse, and what the response is if that happens – reprice, hedge, or absorb. Three sentences is enough. The point is not sophistication; it is that the question has been asked before the market asks it for you.
