Natural Hedging
Natural hedging: settle the currency you owe from the currency you earn.
If you both receive and spend the same currency, the matched slice can pay its own bills. That slice never converts to sterling, so it never pays FX margin on the way out and again on the way back.
This is not the gardening kind of hedging. It is an operational move: line up your foreign income against your foreign costs so the overlap settles itself and only the difference ever crosses into pounds.
Be clear on one thing from the start. Removing the FX margin on the matched slice is real, but it does not make the payment free. Zero margin is not zero cost.
Paying a dollar supplier from a held dollar balance still triggers a flat cross-border or local-rails payment fee, the account itself can carry monthly or holding fees, and the residual you do convert still pays margin.
Matching needs no hedging instrument. No forward to book, nothing to buy. Holding the currency between receipt and payment does need an account, usually an e-money provider rather than a bank.
That account is a tool, not a hedge, and it is not free. Currency Expert compares providers and never holds client funds.

How the match removes the exposure
Match once and you avoid two FX margins. That is the whole mechanism, and it is worth having straight before any numbers.
Currency in against currency out
A UK firm that earns dollars and pays dollar suppliers can settle the dollar invoices straight from the dollar receipts. Only the net difference between what you earn and what you owe ever crosses into sterling.
The offset exists only inside the same currency. Dollars you earn can pay dollars you owe. They do nothing for a euro bill, because a euro payable has no dollar receipt behind it. Match currency by currency, or you are not matching at all.
The round trip you stop paying
Picture the same dollar without a match. The receipt lands and you sweep it into sterling, paying one FX margin. Then the supplier invoice falls due, so you buy the dollars back, paying a second FX margin. Each matched dollar is converted twice.
That is roughly two one-way margins on the matched amount, not one spread. When you pay the supplier directly from the receipt, the dollars never convert, so neither margin is charged. Match once, avoid two margins.
The rule to carry into the numbers
Matching does not win you a better rate. It removes the two conversions you would otherwise pay on the slice where your income and your costs are in the same currency.
True matching: pay foreign costs from foreign income
Four moves that genuinely remove the FX margin on matched flows. Each one creates a real offset rather than shifting the risk elsewhere.
Match receivables to payables
Settle the foreign invoices you owe out of the foreign invoices you collect. The base case, and the cheapest, wherever your inflows and outflows share a currency.
Buy from suppliers in the currency you earn
A supplier who invoices in your earned currency creates a real payable against your existing receipt, so the exposure is netted on your books. The dollars you receive now have a dollar bill to pay.
Hold a multi-currency account
An account that lets you keep the matched currency rather than force-convert it. Treat it as a matching tool, not a hedge. It removes the conversion, not every cost, as the next section sets out.
Net across group entities
The group-scale version. Aggregate same-currency flows across your entities and convert only the residual. Powerful if you have the entity structure, and out of reach for most owner-managed firms.
Where the cost really sits
Two of those moves carry a cost that glossy copy leaves out. We name both before you rely on them.
The supplier who invoices in your currency has priced the risk in
When a supplier bills you in the currency you already earn, they take on the currency risk instead of you, and they price it into the number they quote. The cost does not vanish. It moves into the unit price, where you cannot see it.
This is the load-bearing difference from simply shifting risk, which we come to next. Here an offset is genuinely created, so your net position falls. You are paying for that offset inside the price, but the exposure is real and it is smaller.
The multi-currency account is a tool, and it is not free
Holding the matched currency stops you converting on autopilot, and matching removes the FX margin on that slice. The account behind it still carries costs you should count.
An e-money provider can charge a monthly or holding fee. Paying a supplier out of the held balance still incurs a flat cross-border or local-rails payment fee. And the provider still takes an FX margin on the residual you do convert. The saving is on the matched slice, not on the whole payment.
That balance usually sits with an e-money institution and is safeguarded rather than FSCS-protected. The two are not the same, and the difference matters if the firm fails.
Our business multi-currency account and safeguarding guide sets out how the money is held and what safeguarding does and does not cover.
Netting, and the structure it demands
Netting aggregates same-currency flows across group entities and converts only the residual. Bilateral netting offsets between two companies; multilateral netting replaces many payments with one net figure per entity per cycle.
The part the brochures skip is the plumbing. It needs intercompany netting agreements, a fixed netting calendar and clean transfer-pricing treatment. Most owner-managed importers simply do not have the entity structure to use it, and should not feel they are missing a trick.
Financing in the currency you earn, a foreign-currency loan serviced by foreign revenue, is the same idea at the balance-sheet level. It sits outside this page, but a finance director should know it belongs in the same family.
The honest line
Matching is free of FX margin on the matched slice. It is not free. The account, the per-payment fee and the cash you tie up are all real, and they belong in the decision alongside the margin you save.
Shifting the risk is not matching it
Invoicing your own customers in sterling looks like a hedge. It is a different move, and it is worth keeping the two apart.
Invoicing your customers in sterling creates no offsetting position anywhere on your books. It removes your exposure only by handing it to the buyer. Nothing on your side nets off.
Hold it against the supplier point above. A supplier who invoices in the currency you earn creates a real payable that nets against your receipt, so your net position falls.
A customer you invoice in sterling creates no such offset. You simply pass the exposure across the table. Same priced-in mechanism, opposite effect on your position, and that is the whole point.
The pricing consequence is concrete, not a vague warning about losing the deal. The buyer now carries the currency risk and prices it into what they will accept or pay.
You can lose on the headline number what you saved on the conversion, and against a price-sensitive buyer you can lose the order outright.
Shifting belongs in the toolkit. It earns its place only where you have the pricing power to make the counterparty absorb the risk cheaply. Where you cannot, we would treat matching as the honest move and shifting as a discount in disguise.
A worked example: $800,000 of revenue against $600,000 of costs
One dated calculation, with the assumption stated so you can redo it against your own numbers.
Worked example
We assume a 0.5% FX margin each way. That is an assumption for the illustration, not a quoted rate; get live quotes for your own. Sold to sterling and bought back, the matched dollars would carry roughly 1.0% across the round trip.
The matched $600,000 at 1.343 is about £446,800. Paying the suppliers straight from the receipts avoids that 1.0%, which is close to £4,470 of FX margin you do not pay. This only nets because the receipts and the payables are both in dollars.
Measure that against the right baseline. The saving is real only against a firm that sweeps every receipt to sterling and then rebuys dollars to pay suppliers. A firm that would have held the dollars anyway saves nothing versus its own behaviour, so the number to beat is the auto-conversion habit.
The timing has to work too. The match holds only if the dollar receipts land before the dollar payables fall due. If they do not, you hold an exposed balance in the meantime, which is the limit set out below.
Even on the matched slice, you still pay the flat per-payment fee to settle each supplier. The £4,470 is the avoided FX margin, not the whole cost of paying.
The residual net $200,000, about £149,000, stays fully exposed. It still needs a decision, and that is where a forward earns its place rather than matching.
Where natural hedging quietly leaves you exposed
The gaps that matter, including the treasury cost most write-ups leave out.
Timing: the money lands on the wrong day, and the buffer ties up cash
Timing carries two costs, not one. A balance held while it waits for the payable is exposed to the rate moving in the meantime, the same open risk the match was meant to avoid.
The second cost is the one glossy copy skips. Money you park in a foreign balance to bridge a timing gap, and any buffer you hold against future mismatches, is working capital you cannot deploy in sterling.
That is a treasury trade-off: you are choosing to leave cash idle and exposed to save a conversion. On a large buffer, the idle-capital cost can outweigh the margin you saved.
Volume drift: revenue outgrows the costs it offsets
A match that lines up today drifts apart as the business grows. If your foreign revenue outpaces the foreign cost base it was offsetting, a residual builds quietly, and it is exposed until you notice it and act on it.
It does nothing for translation on the balance sheet
Matching manages the cash you move. It does little for translation risk, the swing in the sterling value of foreign assets, balances or subsidiary results when you consolidate. If that sits on your balance sheet, matching your payment flows will not touch it.
Before you hold a balance abroad
A held foreign balance is safeguarded, not FSCS-protected.
Money you hold with an e-money provider to run a match is safeguarded in segregated accounts under FCA rules, kept apart from the firm’s own funds. That is real protection, and different in kind from a bank deposit.
The FSCS deposit guarantee, £120,000 per eligible person or business since December 2025, covers UK-authorised banks, building societies and credit unions. It does not cover money held with an e-money institution, whatever the balance.
If a provider implies FSCS cover on a safeguarded balance, treat it as a reason to ask more. The FCA’s safeguarding regime also tightens from May 2026.
Our view: match first, then hedge only the residual
The order matters, and it is different from a forward-first approach.
Natural hedging is the cheapest first move, because the matched flows carry no FX margin to protect. We would exhaust it before buying anything. Only the net residual left after matching and netting is worth a forward.
Be honest about what the forward then costs. A deposit of roughly 5% to 10% is usually held until settlement, which on the £149,000 residual above is around £7,500 to £14,900 of cash tied up.
Strong-credit clients may get a credit line that drops the upfront deposit toward zero. Either way, a sharp adverse move can trigger a margin call for more cash at short notice.
We keep the mechanics brief here on purpose. Our currency hedging and forward contracts guide sets out deposits, margin calls and settlement in full, so you can size the residual hedge without over-committing.
What to do next
A proportionate sequence, not a project.
- 01
Map inflows and outflows by currency and period. See how much genuinely matches once timing is accounted for, and remember the match exists only currency by currency.
- 02
Hold the matched portion, do not force-convert it. Weigh the account fee, the per-payment fee and the idle-cash cost against the FX margin you save.
- 03
Compare providers for the residual only. The net exposure left after matching is the part worth shopping, whether you buy spot or fix it with a forward.
- 04
Keep us out of the money flow. You contract and transact directly with the provider you choose.

Common questions
Is natural hedging free? +
Matching removes the FX margin on the matched slice, and that is a real saving. It is not free.
The multi-currency account can carry monthly or holding fees, paying a foreign supplier from a held balance still triggers a flat cross-border or local-rails payment fee, and the provider still takes a margin on the residual you convert.
Holding a foreign balance also ties up working capital. The honest line is free of FX margin on the matched slice, not free.
Does it remove all currency risk? +
No. It removes the risk only on the slice where your income and costs share a currency. The residual net position, any timing gap you bridge with a held balance, and translation risk on the balance sheet all stay open. Matching shrinks the exposure; it does not close it.
Can I match USD income against a EUR bill? +
No. Matching is currency by currency. The offset exists only within the same currency, so dollars you earn can settle dollars you owe, but they do nothing for a euro payable. A euro bill needs euro income, or a separate decision on how to convert.
Why does buying from a supplier in your own currency not make the cost disappear? +
Because the supplier takes on the currency risk and prices it into the number they quote. The cost does not vanish; it moves into the unit price, where you cannot see it. What you gain is a real offset against your receipts, not a free lunch.
What is the difference between matching my costs and just invoicing customers in sterling? +
Matching creates an offset on your books, so your net position falls. Invoicing customers in sterling creates no offset; it hands the exposure to the buyer, who prices it into what they will pay. One shrinks your risk, the other passes it across the table.
What is currency netting, and would a small importer use it? +
Netting aggregates same-currency flows across group entities and converts only the residual. It needs intercompany agreements, a fixed calendar and clean transfer pricing. Most owner-managed importers do not have the entity structure for it, so it is rarely the right tool at that scale.
Do we still need a forward if we match? +
Usually, for the residual. Match first, because the matched flows carry no margin to protect. Then a forward can fix the net exposure that is left. A forward usually needs a deposit of roughly 5% to 10% of the contract, held until settlement, so size it to the residual, not the gross.
Is money safe in the multi-currency account I hold the match in? +
It is safeguarded in segregated accounts under FCA rules, not covered by the FSCS deposit guarantee that applies to banks. Our multi-currency account and safeguarding guide explains what safeguarding protects and what it does not.
