Many UK businesses with international operations don’t actively manage their currency exposure. Instead, they rely on the Spot market to convert currency to pay counterparties and accept whatever rate is available on the day.
While currency management has greater complexities, for companies with recurring FX commitments, this is like being a regular supermarket shopper without a loyalty card. It’s not necessarily wrong or a budget-buster, and there can be valid reasons you might not want to use a loyalty card, but it means if you compare the sum total to the discounted total, it might make you wince.

What currency management is
Currency management is the practice of identifying, measuring and controlling how exchange rate movements affect business costs and revenues.
Every business that pays or receives money in a foreign currency carries exchange rate exposure. A UK company paying a German supplier in euros is exposed to movements in the GBP/EUR rate; a strengthening in pound sterling can make paying invoices cheaper, while a weakening can make them more costly.
Businesses deploy currency management principles to help reduce the impact of exchange rate fluctuations, support profit margins and make the most of multi-currency growth opportunities.
Many growing businesses already practise a form of currency management without realising it. Accessing the Spot market, they convert funds when invoices fall due, accept the prevailing exchange rate and move on. Treating currency exposure as something to monitor and manage, rather than something to react to, gives finance teams greater control over costs and can make future cash flows more predictable
Currency management comprises three essential categories:
- Risk identification: Uncovering exactly where and when foreign currency exposure enters your P&L or balance sheet.
- Risk mitigation (or Hedging): Deploying financial instruments like Forwards and Options help manage the impact of adverse market movements.
- Operational execution: Setting up the accounts, local payment rails, and workflows to handle physical cash efficiently.
Identifying your FX risk is the starting point. For some companies, that will mean learning about the risks of a Spot-only approach to cash management; for companies at a more advanced stage, that might mean managing rolling hedging programmes with Forwards, Options and limit orders.
Why growing businesses neglect FX risk
SMEs often neglect to manage the FX risk that their international operations generate. The question is why.
The first is visibility. Commonly, companies convert currency via their banking partner, commonly well-known high street banks. These banks make money from selling currency by introducing a spread into the rate. Currency buyers pay the mid-market rate (i.e. the rate closest to the “true” value of a currency pair) plus an undisclosed margin. The banks don’t make their take explicit, instead bundling it into one single rate they offer to the customers. It’s easy to assume the rate is the exchange rate if you’re not wise to the dynamics of the FX market.
The second is familiarity. Research by Bibby Financial Services found that around 70% of UK SMEs rely on their existing bank for foreign exchange. For a finance team without specialist FX knowledge, it feels natural to turn to their banking partner. Bank of England data indicates that 59% of FX transactions are Spot trades, compared to around 25% for Forwards and 15% for Options. The market is dominated by as-and-when FX conversions.
The third is (perceived) complexity. While most SME finance teams will have at the very least heard of the common FX instruments, they might write them off as the preserve of dedicated treasury teams, or lack confidence in how best to use them.
The combined result is that SMEs fork out, on average, £17,000 per year for FX, through unfavourable conversion rates, the timing of trades, and a lack of hedging.
We cover this, and more, in the blog, How UK Businesses May be Paying More for FX than they Need to.
How to identify and quantify FX risk exposure
Before selecting any instrument or setting any policy, a business needs to know where it’s exposed to foreign currency risk and how large the risk is.
A company needs to identify every point in the business where a foreign currency enters or leaves. Most UK SMEs with international operations will find exposure among the three following categories:
Cost-side exposure
This includes supplier payments denominated in a foreign currency, whether for raw materials, finished goods, software licences or professional services. It also includes overseas payroll and contractor costs paid in local currencies.
Revenue-side exposure
A UK business invoicing clients in dollars or euros faces uncertainty about the sterling value of that income between the date the invoice is issued and the date payment arrives. The longer the payment terms, the wider the window of exposure.
Balance sheet exposure
A business holding foreign currency assets or liabilities, whether cash balances, receivables, intercompany loans or foreign-currency debt, faces revaluation risk when those items are translated into sterling for financial reporting.
Once the sources of exposure are identified, the next step is measurement. The relevant figure is net exposure by currency, not gross. A business paying €200,000 per quarter to European suppliers and receiving €80,000 per quarter in euro-denominated revenue has a net euro exposure of €120,000 per quarter. Hedging against the gross figure would leave the business over-hedged, tying up capital unnecessarily and creating its own risks if commercial volumes change.
The timings of exposure create risk as well. Exposure that clusters around specific dates, such as quarter-end supplier payments or annual licence renewals, creates concentration risk: a single unfavourable rate movement on the wrong day affects a disproportionate share of the total.
For a more detailed look at how different types of exposure translate into different hedging approaches, see our overview of FX hedging strategies for growing businesses.
The currency management toolkit
Note: Forward contracts and FX options are regulated financial instruments classed as derivatives. They carry risk, including the risk of loss, and may not be suitable for every business. Before entering into any hedging product, you should consider whether it is appropriate for your needs and circumstances.
With exposure identified and measured, the question becomes which instruments to use. There are three core tools available to UK businesses managing currency risk.
Spot FX
Spot FX is the immediate conversion of one currency into another at the current market rate (plus a fee), for near-instant settlement. It is the most basic form of currency transaction and is always available. Spot FX provides no protection against future rate movements. Its role in a currency management framework is to handle immediate, known requirements rather than to manage risk.
Forward contracts
Forwards allow a business to agree an exchange rate today for a currency conversion that will settle on a specified future date. The rate is fixed at the point of booking, which means the cost or value of the future transaction is known in advance. This is useful for predictable commitments such as quarterly supplier payments, scheduled payroll or contracted purchases.
Forwards carry their own risk, too: a Forward is a binding obligation, so if the market moves in the business’s favour before settlement, the business cannot benefit from the improved rate. Forwards also typically require an initial margin deposit and may be subject to variation margin if the market moves significantly against the position. For a full explanation of how Forwards work, including the different types available, see our guide on what is an FX Forward contract.
FX Options
FX Options give a business the right, but not the obligation, to exchange currency at an agreed rate on or before a set date. The business pays a non-refundable premium for this right. If the market moves against the business, it can exercise the option and transact at the agreed strike rate. If the market moves in its favour, it can let the option lapse and convert at the better market rate instead. Options are particularly suited to situations where the exposure itself is uncertain, such as a contract bid that may or may not be won, or a project quote in a foreign currency where the final scope is not yet confirmed. The premium is the cost of retaining that flexibility. For a detailed look at how Options work, the risks they carry and when they apply, see our guide on FX Options for businesses.
These three instruments are covered in depth, with worked examples, in our guide on currency hedging for businesses: Spot, Forward or Option.
Cash management
Cash management is the final tool in the currency management toolkit.
Cash management is less about using instruments to hedge risk, and more about handling, holding and moving cash as efficiently as possible. A key principle in cash management is minimising the number of cash conversions. The fewer unnecessary conversions a business makes, the lower its aggregate FX cost.
For instance, a UK business that converts euro revenue received from European clients into sterling, that then converts back to euros to pay European suppliers, is paying for two conversions where it could be paying for none. In comparison, holding a euro balance and using it to settle euro-denominated costs removes the conversion cost and avoids exchange rate risk on that portion of the flow.
Multi-currency accounts make this possible by allowing a business to hold balances in the currencies it trades in. Rather than routing every inflow through a sterling conversion, the business receives funds in the original currency and chooses when, or whether, to convert. This also supports natural hedging: where foreign currency inflows and outflows are in the same currency and roughly similar in scale, the business can offset them directly without using a financial instrument.
It’s not only currency conversion that eats away at revenue and profits. When transacting internationally, payments can be subject to various fees and delays when accessing local payment rails. Transitioning to local payment infrastructure, such as SEPA through the use of virtual IBANs, “makes all cross-border electronic payments in euro as easy as domestic payments”, per the European Commission. This streamlining of transactions by routing funds directly through local clearing systems significantly reduced intermediary fees while accelerating settlement speeds.
For a detailed look at how virtual IBANs work and when they are useful, see our guide on virtual IBANs for business.
Building a currency management strategy
Knowing how FX instruments work is a good start, but the art lies in how they’re used. This section will look at hedge ratios, how companies build positions over time, and what rolling hedges are and how they work. As with all FX hedging products, Forwards and Options carry risk and may not suit every business.
Determine appropriate hedge ratios
A 1:1 match can be called a 100% hedge ratio. It might sound like a safe approach – you’re hedging all your exposure – but it’s rarely the most practical. Future forecasts can change, sales may not materialise, supplier orders may be delayed, project costs may shift, or exchange rates might move favourably. A downside risk of hedging is that it reduces agility: the deposit that a hedge requires to book is capital that can’t be used until the position is executed. That can make a company less nimble at responding to changes in the market.
Hedging too much can leave a business over-hedged, creating unnecessary transactions to unwind positions or hedging risks that no longer exist.
For that reason, many businesses adopt a partial hedge ratio. The balance between fixing an exchange rate and accepting upside and downside risks of the Spot market is particular to each company and their operational objectives, but the objective remains the same: reduce unwanted currency risk without sacrificing unnecessary flexibility.
Build positions over time
The unpredictable movement of exchange rates mean that many businesses look to build positions gradually, rather than placing all future exposure into a single trade. This layered approach spreads execution across multiple dates, reducing the risk of locking in an unfavourable exchange rate simply because of timing.
Layering can also make budgeting more stable. Instead of future costs depending on one exchange rate, they reflect an average of several market levels over time, helping to smooth the impact of short-term volatility.
Create rolling hedging programmes
Businesses with recurring foreign currency commitments often benefit from a rolling hedging programme rather than making ad hoc decisions whenever payments become due.
For example, a company paying overseas payroll every month or settling quarterly supplier invoices can maintain a consistent programme that extends several months ahead. As one hedge matures, another is added to maintain the desired level of protection.
Rolling programmes replace reactive decision-making with a repeatable process. They reduce the temptation to delay hedging in the hope of a better exchange rate and can provide greater certainty over future costs.
For a practical overview of hedge ratios, layered positions and rolling programmes, see our guide on FX hedging strategies for growing businesses.
Measure performance through reporting
As your business grows, cash flows change and market conditions evolve, your approach should evolve with them.
Regular reporting, aided by integrating hedging platforms with accounting software, allows finance teams to compare hedged positions against actual exposures, monitor remaining currency risk and assess how effectively the strategy is meeting its objectives. It also highlights issues such as over-hedging, under-hedging or changes in forecast cash flows.
The purpose of reporting is not to judge whether an individual trade beat the market. Currency markets are inherently unpredictable. Instead, reporting should answer a more useful question: is the strategy delivering the level of certainty and risk reduction it was designed to provide?
How operational infrastructure enables currency management best practices
For most growing businesses, currency management isn’t handled by a dedicated treasury team, but by the finance team, with contributions from other functions. That makes the supporting infrastructure just as important as the hedging strategy itself. The right platform should make currency management repeatable and transparent, rather than dependent on phone calls, spreadsheets or individual expertise.
Businesses today can choose between broker-led services, where trades are arranged through a relationship manager, and self-service platforms that allow finance teams to execute, monitor and report on currency activity directly. Many modern platforms also integrate with accounting software, ensuring payments and hedging transactions flow automatically into the general ledger, reducing manual reconciliation and improving auditability. Role-based permissions allow businesses to separate responsibilities, so team members can initiate payments or prepare transactions without giving every user authority to approve or execute them.
As transaction volumes grow, many businesses also move away from manual execution towards automation. Scheduled payments, recurring hedging programmes and predefined execution rules reduce administrative workload while ensuring decisions are carried out consistently. Platforms such as Alt21 bring these capabilities together in a single environment, combining multi-currency accounts, FX execution, hedging and reporting without requiring the resources of a traditional treasury function.
