TL;DR: If you agree a price in one currency but get paid or pay your supplier later, exchange-rate movements can change your profit before the money settles. On a deal with a 4% margin, a 2% adverse currency move could wipe out half that margin. Businesses can manage this risk by locking in a rate with a forward, averaging their exposure over time, or setting a range for the rate. Bound, an FCA-regulated FX hedging platform, lets you hedge with no cash deposit, see the exact spread (see glossary) before you confirm, and change dates and amounts yourself online if plans change.
You agree a deal at a 4% margin, with payment due in 60 days. By the time the invoice settles, the exchange rate has moved 2% against you. Half your margin could be gone.
That is the FX risk importers and exporters face when they buy or sell in foreign currencies. The risk starts when you commit to a price and continues until you pay or get paid. If the exchange rate moves against you during that time, the cost of the deal in your reporting currency changes and your margin can shrink.
This article explains when FX risk arises in an import or export deal, how exchange-rate movements can affect thin margins, and three ways you can manage that risk without needing to become an FX specialist.
Why currency risk matters for thin-margin businesses
How exchange-rate movements affect your margins
Every price you quote in a foreign currency assumes an exchange rate. When you buy from a supplier in USD and sell to customers in EUR, the margin you priced only holds if the rate at settlement matches the rate you assumed. Any move between those two points changes your actual margin, in either direction.
The FX risk starts as soon as you agree a price in a foreign currency. From that point until you pay or get paid, exchange-rate movements can change the margin you ultimately make. Export Development Canada notes that FX risk begins when you quote a price in a foreign currency, not when you invoice or receive payment, and the US International Trade Administration makes the same point: the relative values of two currencies can change between the time a deal is concluded and the time payment is received.
The invoice-to-settlement exposure window
A typical importer’s FX exposure might look like this:
Quote accepted: you agree a EUR price with your customer, based on an assumed USD cost from your supplier.
Purchase order placed: you commit to a USD payment, typically settling 60 to 90 days out.
Payment due: you buy USD at whatever rate the market offers on the day.
How a 2% exchange-rate move can affect your margin
The maths on a thin margin are unforgiving. Currency fluctuations can quickly affect profit margins when costs and revenue sit in different currencies: if your supplier's currency strengthens, you pay more for the same goods and your margin on each sale shrinks. Even a move of a few percent can turn a profitable order into a loss.
Take a €5,000,000 purchase priced at a 4% gross margin, so €200,000 of profit. To keep the example simple, assume the full cost of the purchase moves with the exchange rate and ignore other costs:
Currency shift | Cost impact | Margin remaining |
|---|---|---|
1% adverse | €50,000 | €150,000 (75%) |
2% adverse | €100,000 | €100,000 (50%) |
3% adverse | €150,000 | €50,000 (25%) |
5% adverse | €250,000 | -€50,000 (loss) |
In this example, a 2% adverse move halves the profit, and a 5% adverse move turns the deal into a loss. Rates can also move in your favour, which would add to the margin, but a favourable move is a windfall rather than a plan. On a 4% margin, the question is how much of that profit you are willing to leave to the exchange rate.
Where FX exposure comes from
Managing risk on supplier payments
If you buy from overseas suppliers in a foreign currency, the amount you ultimately pay in your reporting currency can change before the invoice is due. For example, if you need to pay a supplier in USD but report in EUR, a stronger dollar means you need more euros to pay the same USD invoice. This exchange-rate risk exists from the moment you commit to the purchase until you make the payment.
FX risk on foreign currency receipts
Exchange-rate risk also applies to money coming into the business. If you sell to customers in EUR but need to convert that revenue into USD, the value of your receipts can change before you convert them. If the euro weakens against the dollar, the same EUR revenue will be worth less in USD. Hedging can help reduce the uncertainty around what those future foreign-currency receipts will be worth.
Managing multi-currency cash flows
The mismatch is the real problem: purchases in USD, sales in EUR, books in EUR. Exposure sits on both sides, scattered across invoices, purchase orders and payment runs, with no consolidated view. When you connect Bound to your accounting software, the platform calculates your total FX exposure automatically, removing the manual tracking step entirely. Integration is optional, and many customers run Bound without it.
How importers and exporters manage FX risk
Importers and exporters can either wait and convert currency at the spot rate when a payment is due, or hedge in advance to reduce uncertainty around future costs and revenues. The right approach depends on the type of exposure your business has and how much certainty you need.
Managing FX risk at settlement
A spot conversion exchanges currency at the prevailing spot rate for immediate settlement, typically within two business days. Spot is a settlement instrument that gets the payment done but accepts whatever rate the market offers on the day, so it does nothing to protect a margin you priced 60 days earlier.
Locking in exchange rates early
An FX forward lets you agree an exchange rate today for a payment on a specified future date. Like a purchase order that locks a price before goods ship, a forward fixes the rate before settlement, and the trade-off is that you give up any upside if the market moves in your favour. Bound's Forwarding strategy suits businesses with thin margins on specific deals where certainty over the rate matters most.
Managing risk with FX options
An FX option gives you the right, but not the obligation, to exchange at a pre-agreed rate, and you pay a premium upfront for that flexibility. Bound's Ranging strategy achieves a similar outcome through a different mechanism: you set a stop and a limit so the executed rate stays inside a band you choose. Timely, a Norwegian SaaS company with USD revenue and NOK costs, set a stop at its budget rate and a limit above it, and when the market hit the limit the platform booked a forward for the rest of the year at that rate, beating its budget rate by 5.4%.
Layering forwards across a programme
The third strategy, Layering (what Bound calls Averaging), splits exposure into smaller forward legs booked daily across a programme, producing a blended rate that suits recurring operating expense exposure. Tines, a workflow automation platform, ran a six-month rolling averaging programme to convert USD into EUR, scaling from $800K to $2M per month as its exposure grew.
How forward contracts fix your rate
Locking the rate when you price the deal
The workflow is simple: price the deal, book the forward, know the rate you'll settle at. The honest trade-off bears repeating: if the market moves in your favour, you still settle at the agreed rate. You are exchanging potential upside for certainty over the outcome.
Ravelin, a fraud detection company, uses Bound's rate-locking capability at invoice time to manage FX exposure on international revenue, giving it revenue certainty and keeping its accounting and P&L data clean.
When a forward can protect your budget rate
A forward can protect your budget rate if the exchange rate you lock in is at or better than the rate your budget assumes. Once booked, that rate is fixed regardless of how the market moves before settlement, as explained in Bound's CFO guide to FX risk.
If the available rate has already moved beyond your budget rate by the time you hedge, a forward cannot recover that difference. It can give you certainty from that point onwards, but it will lock in a rate that is already worse than your budget.
Managing FX without tying up cash
Brokers and banks may ask for collateral on forward contracts, typically without offering a no-deposit alternative. Bound offers forward contracts with either a 5% margin deposit (see glossary) or no cash deposit. For businesses with annual FX flow under $20M, pricing starts at a 0.45% spread with the deposit or 0.75% without. The no-deposit option has a higher spread, giving businesses a choice between lower pricing and keeping more cash available.
Where a margin arrangement is in place, the security transfers under a Title Transfer Collateral Agreement (see glossary), which is not available to retail clients, and Bound may request additional margin if a position moves out of the money during the life of the forward.
Adjusting FX hedges when trade plans change
How to edit your existing hedges
Payment dates move and order volumes change. On Bound, you change dates and amounts yourself in the platform, and the fee is shown before you confirm. Changing the date costs 0.05%, and decreasing the amount also costs 0.05%. If you need to increase the amount, the additional exposure is treated as a new booking, costing between 0.25% and 0.75% depending on your pricing tier. The additional amount is booked at the prevailing forward rate.
With a broker, amendments may require a phone call, and costs are typically not disclosed in advance. The mechanics are set out in Bound's article on budget rate protection.
Handling partial drawdowns and splits
If you booked a forward against an estimated amount and the confirmed invoice arrives lower, you can draw down part of the position or split it into multiple trades yourself. Bound's guide to hedging overseas supplier payments walks through the workflow.
Unwinding a forward contract early
Closing a forward early is different from amending one. A mark-to-market amount (see glossary) may be settled, which can be positive or negative for you depending on how rates have moved. Amending the date or amount may be an option when circumstances change.
The table below contrasts the two operating models:
Consideration | Converting through a bank or broker | Using a forward with Bound |
|---|---|---|
Pricing transparency | Provider's margin typically built into the quoted rate | Spread shown as its own line before you confirm |
Execution | Some trades require phone calls or emails | Self-serve online, in a few clicks |
Amendments | Depending on the provider, changes may require a phone call or email, and fees may not be shown in advance | Make changes yourself online, with the fee shown before you confirm |
Exposure tracking | Future requirements may need to be tracked manually | Calculated automatically from connected accounting software |
Day-to-day management | Rate monitoring sits with you | Trades execute against the strategy you chose |
Spotting the hidden fees in bank FX quotes
Identifying bank spread charges
An FX spread is the difference between the buy price and the sell price of a currency pair. The midpoint between the two is known as the mid-market rate. The difference between the rate you receive and the mid-market rate reflects the spread, which is where the cost of the FX transaction sits. Banks typically build their margin into the quoted rate rather than disclosing it as a line item, and that markup does not typically appear as a fee on statements.
Find the mid-market rate. This is the midpoint between the prices banks buy and sell a currency at. It’s a useful reference point because it has no margin added. For a rate close to when you traded, use Bloomberg FX Fixings. Bloomberg calculates these every 30 minutes and shows a selection for free, with a short delay. If a daily reference is enough, the Bank of England publishes indicative rates taken around 4pm London time.
Find your rate. Your trade confirmation shows the rate you got and the time you traded. Compare it with the mid-market rate for the same currency pair, as close to that time as you can.
Work out the margin. Subtract one rate from the other and ignore any minus sign. Divide the result by the mid-market rate, then multiply by 100. Example: the mid-market rate is 1.1800 and your rate is 1.1741. The difference is 0.0059. Divide 0.0059 by 1.1800 and multiply by 100: your margin is 0.50%.
What this check doesn’t cover Forward contracts. These lock in a rate for a future date. Their rates include forward points, an adjustment for the difference in interest rates between the two currencies. That means you can’t compare a forward rate directly with today’s mid-market rate. Separate fees, such as payment charges or option premiums. Your costs and charges statement shows everything you pay.
Bound's rate alerts tool tracks the real mid-market rate, which gives you a standing benchmark rather than a one-off check.
Identifying true exchange rate costs
For every trade, Bound gets competing quotes from several major liquidity providers and uses the best available price. Bound's spread is then shown separately before you confirm the trade. This means you can see what you are paying rather than having to work it out from the exchange rate yourself.
You can read more about how Bound handles orders in its best execution policy.
For forward contracts, the rate also reflects the interest rate difference between the two currencies, known as forward points (see glossary). When those forward points are positive, Bound passes that benefit on to you rather than keeping it.
Tiered pricing based on FX flow
Bound's forward pricing tiers by annual FX flow, with no setup fees, no monthly fees, and no per-seat charges:
Annual FX flow (USD) | 5% margin deposit | 0% margin deposit |
|---|---|---|
0-20M | 0.45% | 0.75% |
20-50M | 0.40% | 0.65% |
50-100M | 0.35% | 0.60% |
100-250M | 0.30% | 0.55% |
250M+ | 0.25% | 0.50% |
Spot conversion starts from 0.03% with no deposit required.

FAQs
How far in advance should I lock in a rate?
With Bound, you can hedge up to 24 months in advance. How far ahead you choose to hedge depends on when you expect to pay or receive the foreign currency and how certain you are about the amount and timing. For example, if you place an order with an overseas supplier and payment is due in 60 to 90 days, you may have FX exposure throughout that period.
What if the deal falls through after I book a forward?
If the underlying deal changes, amending the date or amount is an option. Closing the forward early is at Bound’s discretion. You’ll pay or receive the mark-to-market amount.
Can I hedge without tying up cash as margin?
Yes. Bound's no-margin forward pricing starts at 0.75% for annual FX flow under $20M, compared with 0.45% when you provide 5% margin at the same tier.
How do I know if I'm getting a fair rate?
Compare the quoted rate against the mid-market rate at the time of execution. Bound shows its spread as a separate line before you confirm.
Do I need a hedging policy to get started?
A single forward on a specific deal is a valid starting point. A documented FX hedging policy helps as volumes grow and the number of exposures increases. We can help, see our hedging policy.
Which strategy suits an importer on thin margins?
Forwarding may suit thin margins on specific deals because it locks a rate for a future settlement date. Averaging may suit recurring operating expense exposure, and Ranging typically suits businesses that do not want to lock in today but have a budget rate to protect.
