When Sterling Swings: A Currency-Risk Discipline for UK Mid-Market Boards

The board question is usually framed as a prediction: where will sterling go next? It is the wrong question. No mid-market board can reliably forecast exchange rates, and a finance team that tries to do so is being drawn into trading rather than risk management. The better question is whether the business can explain, in plain terms, how a movement in sterling would affect its margins, cash flow and covenant headroom over the next twelve months.

For UK SMEs with international customers or suppliers, currency risk is often dispersed across the business. A sales team quotes in euros, a procurement team buys components in dollars, and finance reconciles the difference at month end. Individually, each decision may seem sensible. Collectively, they can create a speculative position that nobody has approved.

The board question is not what sterling will do

Currency risk comes in several forms. Transaction risk arises from known or forecast cash flows in a foreign currency. Translation risk affects the reported value of overseas assets and liabilities. Economic risk is broader, affecting competitiveness when exchange rates shift. For most mid-market firms, transaction risk deserves the first and most practical attention.

The board should agree a risk appetite in plain language. For example: the business will hedge a defined proportion of confirmed foreign-currency cash flows, will not take positions based on market views, and will review cover monthly. That statement is more valuable than a quarterly debate about the direction of the pound.

A twelve-month rolling exposure map is the foundation. It should list currency, amount, expected timing and certainty. Invoiced amounts are the most certain. Committed orders are next. Forecast sales should be treated with caution. The map should net receipts against payments in the same currency before any hedging decision is made.

Natural hedging before derivatives

The first response to currency risk is not a forward contract. It is to reduce the gross exposure. If a UK manufacturer sells into the euro area and also buys components priced in euros, it can offset those flows. The finance team should ask whether receipts and payments can be matched more closely, whether a multi-currency account would help, and whether invoicing in sterling is commercially realistic.

Passing currency risk to a customer or supplier is not free. A European customer asked to pay in sterling may demand a price concession or simply choose a competitor. A UK buyer that insists on paying in dollars may find suppliers less flexible. Currency choice is a commercial term, not a technical one, and should be negotiated with the same care as payment days and delivery terms.

Payment timing also matters. Shortening receivables and aligning payables can reduce the period during which the business is exposed. These steps do not eliminate risk, but they make the remaining exposure smaller and easier to manage.

Forward contracts in plain English

A forward contract fixes an exchange rate for a future date. It is a budgeting tool, not a bet on sterling. If a UK exporter expects to receive euros in six months, a forward contract allows the finance team to convert that future receipt at a known rate today. The business gives up the chance to benefit from a more favourable move, but it also removes the risk of a less favourable one.

For mid-market firms, simplicity is a virtue. Vanilla forwards are widely understood and easy to explain to a board. More complex products may have their place in larger treasury functions, but they can obscure the risk rather than reduce it. The board should be cautious about any instrument it cannot describe in one paragraph.

Forwards require a bank facility and may require collateral or a deposit. The finance team should understand the credit line impact before signing. It should also avoid over-hedging. A common discipline is to hedge a proportion of confirmed exposure, such as half to three-quarters, and to treat forecast sales separately. Layering cover over several months can smooth the rate without trying to pick a peak.

Payment terms are a hedging tool

Currency risk and working capital are connected. A long receivable in a volatile currency is both a credit risk and an FX risk. Negotiating shorter payment terms, or agreeing progress payments on larger contracts, can reduce the exposure window. On the payables side, matching supplier payment dates to expected customer receipts can improve natural offset.

Contract clauses should be clear about the invoicing currency, the exchange-rate basis for any price adjustment, and who bears bank charges. Where a customer insists on local-currency invoicing, the UK supplier should either price the risk or hedge it. Leaving it unhedged is a decision, even if it is not written down.

Governance without a trading desk

A mid-market business does not need a treasury department to manage currency risk well. It needs a written policy, clear roles and regular reporting. The board approves the policy. Finance identifies and measures exposure. A named person executes within limits. The CFO or finance director reviews positions. The board receives a short monthly report showing exposure by currency, hedge cover, average rates and the impact of a stress scenario.

Limits should cover tenor, percentage of exposure hedged, permitted instruments and counterparties. The policy should state that no positions are taken for speculation. It should also require segregation of duties, so that the person initiating a hedge is not the only person approving it. An annual independent review, even a light one, can test whether the policy is being followed.

Hedge accounting is a separate question. Some SMEs will not need it, but where foreign-currency debt or large contracts are involved, the finance team should speak to its auditor early. The accounting treatment should not drive the commercial decision, but it should not be discovered after the fact either.

A practical 2026 action plan

A sensible sequence is to build the exposure map, agree a one-page policy, reduce gross exposure through natural hedging, layer simple forwards over confirmed cash flows, review contract terms and report monthly to the board. A stress test is useful: what would a ten per cent move in sterling do to gross margin and cash headroom? If the answer is uncomfortable, the business has a risk management issue, not a forecasting issue.

The board does not need to predict sterling. It needs to know what the business has done, what remains exposed and who is accountable. That is the difference between currency risk as a quiet drag on margins and currency risk as a managed part of international trade.
