Currency Hedging Strategy
You have decided to hedge. The structure is where the money is made or lost.
Structuring a year-long dollar programme, tranche by tranche, so the hedge ratio, the phasing and the maturities each earn their place.
Take a UK importer with roughly £2m of forecast dollar supplier payments over the next twelve months. A 4% move against sterling on £2m is £80,000, decided by the calendar rather than by anything the business did.
Whether to hedge at all is a separate question, and our currency hedging guide answers it on a single supplier payment. This page assumes the decision is made and takes on the harder part: how you structure the programme.
This is a year-long, multi-tranche programme, not that one payment. The same structure mirrors in reverse for exporters, who sell sterling forward and set the ratio on net receipts; that case is covered in our hedging guide for exporters.
Building a currency and FX risk-management strategy is the job here, which is a step beyond the day-to-day discipline of FX risk management itself.
Two decisions sit underneath the whole thing, and they are independent. One is how you phase the buying to average the entry rate, which is layering.
The other is how much cover you hold at each maturity down the curve, which is laddering with a tapered ratio. Keep them apart and the rest of the page follows.

Start with the part of the forecast you can actually stand behind
The ratio is not a market view. It comes from how certain the underlying cash flows are, and from what is left after you net.
Split the £2m before you cover any of it. Some of it is contracted: say £1.2m of firm supplier orders already placed, with dates and amounts you can defend. The rest, roughly £800k, is a pipeline forecast that may or may not arrive.
Only the reliable slice can carry a high level of cover. Hedge the speculative £800k as if it were certain and you risk buying dollars for orders that never land.
Natural hedging belongs here as a structural point, not a separate product. If the same importer also invoiced some sales in dollars, you would match that dollar revenue against your dollar costs by currency first, then hedge only the net. You pay spread and tie up margin on a smaller number.
Our view is plain: shrink the exposure for free before you buy cover for it. The full job of finding and sizing every exposure sits in FX risk management.
The mechanics of matching, timing and structural versus pricing hedges sit in our natural hedging guide. Here we set the ratio on the residual.
How much to cover: setting the hedge ratio
The hedge ratio is the proportion of your residual exposure you actively cover. It is a mechanism, not a number to copy.
The hedge ratio is your hedged exposure divided by your total forecast, residual exposure. On the importer, a 60% ratio fixes £1.2m of the residual and leaves £800k floating.
As a reference point, UK corporate hedge ratios reached roughly 57% to 58% of forecast exposure in the first quarter of 2026, the highest on that record. The most common bracket is 51% to 75%, used by about 61% of UK firms.
That is from the MillTech FX Corporate Hedging Monitor, Q1 2026 edition, checked 14 July 2026.
Because a single survey is thin ground to stand a decision on, a second published account of the same survey wave corroborates the same range and the shift up from about 49% in the prior quarter.
A benchmark is not a target
The ratio you choose comes from how much of your gross margin a rate move would remove, not from what other firms are running. A thin-margin importer covers more of the residual than a business that can absorb a swing.
One flat benchmark ratio quietly over-covers your least certain, most distant periods, because it treats a twelve-month forecast as if it were as firm as next month. The schedule fix for that is laddering, below; what it costs to unwind an over-hedge is in the swap section that follows.
Layering: phasing the buying to average the rate
Layering is the rate-averaging decision. You split the cover into tranches bought at intervals, so your average entry rate does not depend on one buying date.
These are forward-based phasing patterns. Options and collars are a different tool, with an upfront premium that keeps your upside, and we cover that choice in our options versus forwards guide rather than here.
Regular equal tranches
You buy the cover in equal portions at set intervals, for example a fixed slice each month, to average the rate across the year.
- ◆the smoothest weighted average, with the least dependence on any single buying date
- ◆the most settlements, and so the most admin and the most margin events to manage
Fewer, larger tranches
You buy in a handful of bigger chunks at wider intervals, for example one purchase a quarter.
- ◆fewer settlements, less margin churn and less admin to carry
- ◆a lumpier average, and more timing risk per tranche, because each one fixes a larger slice at a single rate
Deliberately, we do not call Pattern B laddering. In UK FX-broker usage, laddering means staggering maturities across the curve, which is the next section. Treating the two as the same thing is the error a market-aware reader will spot, so we keep the words apart.
Laddering maturities: how much cover at each horizon
Laddering is the horizon decision. It staggers when your contracts settle, and a tapered ratio decides how much cover sits on each rung.
Three words get muddled, so we will match them to convention. Laddering staggers forward maturities across the curve, a ladder of contracts settling at different dates.
Tapering, or banding, is the declining ratio profile you apply to that ladder. Layering, from the previous section, averages the rate within your buying.
Tenor has its own cost. The forward points widen the further out each rung reaches, so holding cover to twelve months costs measurably more in pounds than holding it to three. That is not a market forecast; it is the interest-rate differential, which we come back to in the swap section.
UK firms have been hedging further out to bridge medium-term volatility, with the average corporate tenor extending to roughly 6.6 to 7.0 months in the first quarter of 2026, per the same MillTech Q1 2026 edition, checked 14 July 2026.
Taper the ratio down the ladder
Because near-term forecasts are reliable and far-term ones are not, you cover less as you go further out. As a worked shape, hold 80% to 90% of the next quarter, tapering toward 25% to 50% at twelve months.
This is the schedule-level prevention of over-hedging. A taper limits how much cover you hold on the least certain, most expensive-to-unwind rung, which is exactly where one flat ratio would over-cover. The worked example below implements this taper.
When the date moves, and the cost of changing a hedge
The boring, expensive details. Both rolling a hedge and closing out a surplus tranche are executed as an FX swap, and the cost is set by swap points, not by a prediction.
An FX swap has two legs. The near leg closes one contract; the far leg opens or reverses the other. The price of that swap is the swap points, a function of the interest-rate differential between sterling and the dollar under covered interest parity.
The higher-rate currency trades at a forward discount, the lower-rate one at a premium. This is arithmetic, not a view on where the pair is going.
A payment date that moves within a period is a window, or time-option, forward problem, not a rolling one. You draw the currency down in stages across a delivery window rather than on one fixed day.
That matters to the schedule because it keeps a moved date from forcing a swap at all. The full fixed-versus-flexible treatment, including drawdown terms, the wider forward points and the larger deposit a window contract carries, sits in our fixed versus flexible forward guide.
Rolling extends tenor. Short forwards are rolled forward to cover a horizon longer than you want to commit cash for, or when a date slips beyond the original tenor. Each roll costs the forward points for the extended period plus the broker’s bid-ask spread on the swap.
Closing out an over-hedge is the reverse. When a quarter’s forecast £300k of purchasing collapses to £150k, £150k of that rung is stranded: you are committed to buy dollars you no longer need, and you close the surplus as an FX swap marked to market.
A 3% adverse move on that £150k is roughly £4,500 to unwind, before the swap spread.
The working capital a programme ties up
A forward asks for a deposit, and a layered book asks for several of them at once. That is the cost the smoothing does not advertise.
The mechanics of an initial deposit and a margin call are covered on the pillar; our currency hedging guide walks through what each one is. In short, a business forward usually asks for an initial deposit of about 3% to 10% of the notional, applied to settlement rather than charged as a fee.
The insight a single-payment page cannot show is what a layered or laddered book does to that cash. Your importer is long dollars: it buys dollars and sells sterling forward.
So the hedge moves out of the money, and the provider calls for more cash, when sterling strengthens. In one sharp sterling rally, several tranches can hit their triggers together.
That is simultaneous margin calls, a cash-flow event arriving exactly when the smoothing was meant to help. A 5% deposit against £1.2m of hedged notional already locks up about £60,000 until settlement, and the calls sit on top of it.
So a layered or laddered structure makes this cash drag larger, not smaller. It is a real cost of the smoothing the layering section sells, and it belongs in the decision. Unsecured lines with no deposit do exist, but they require rigorous credit assessment and a multi-year trading history.
Read this before you book
Safeguarding is not the same as FSCS protection.
The £60,000 of deposit and any margin you post are safeguarded in segregated accounts under FCA rules, kept separate from the firm’s own money so they can be returned if the firm fails. That is real protection, and different in kind from a bank deposit.
The FSCS deposit guarantee, currently £120,000 per eligible person per authorised firm, covers bank and building society deposits, not cash held with an FX provider. Any provider that implies FSCS cover on a safeguarded balance is one to question.
Worked example: laddering the importer’s year of dollar payments
The same £2m importer from the top. A twelve-month, four-tranche programme, deliberately not the single supplier payment on the pillar.
Worked example
Step A, the naive version. A flat 60% ratio, layered in four equal quarterly tranches of £300k. Simple, and it over-covers the far quarter you are least sure of.
Step B, the redistribution we recommend. The same £1.2m of cover, tapered down the ladder so the tranches are front-loaded: roughly £450k, £350k, £250k and £150k. Still about £1.2m in total, still about £60,000 of margin, but more of the least certain far quarter is left floating.
Step B is better because the far quarter is the one most likely to over-hedge and most expensive to unwind, so it carries the least cover. The four tranches blend into a weighted average exchange rate, the pounds you have fixed against the £800k still floating.
| Rung | Step A: flat 60% | Step B: tapered | Why the taper |
|---|---|---|---|
| Q1 (nearest) | £300k | £450k | firmest forecast, cheapest to hold, tightest forward points |
| Q2 | £300k | £350k | still well-committed orders |
| Q3 | £300k | £250k | softer pipeline, wider forward points |
| Q4 (furthest) | £300k | £150k | least certain and dearest to unwind, so least cover |
Comparing providers for a programme, not a single spot rate
A programme is judged on how it handles many tranches over a year, not on one headline rate.
Our view, owned as opinion
The ratio, the taper and the phasing matter more than the entry date. A tapered, laddered, layered structure removes the temptation to bet a whole year’s exposure on one rate.
The honest trade-off is that you give up the chance of a perfect fill in exchange for a defensible average and a programme that survives a bad quarter. We think that is the right trade for a business protecting a margin, and we say so as a view, not a universal truth.
- ◆support for multi-tranche forwards, not just one booking
- ◆both roll execution and window or drawdown execution
- ◆the deposit percentage and the margin-call trigger and timing
- ◆close-out and cancellation terms on a surplus tranche
- ◆the minimum tranche size you can book
- ◆the reporting you get back, not just the headline spread
The next action is proportionate. Map the next twelve months of exposure, choose a tapered banded ratio, then compare two providers on their forward points, margin terms, drawdown terms and close-out terms against the same tranche schedule.

Write the structure down before you need it
Name the load-bearing items and stop there: agreed hedge-ratio bands, tenor and ladder limits, who authorises each tranche, and whether you report on weighted average rate or mark-to-market.
The one reason that matters is simple. A programme without written bands drifts into ad-hoc rate-timing in a bad month, which is the behaviour the whole structure exists to remove.

Common questions
What is a sensible hedge ratio for an SME? +
It is margin-driven. Cover more of the residual where a rate move would remove real gross margin, and less where you can absorb the swing. The UK average of about 57% to 58% is a reference point, not a target to copy.
Does layering cost more than one bulk forward? +
Yes, in operational terms. You carry more settlements, more admin and more margin events, plus forward points on each tranche. What you buy for that is a smoother weighted average and no dependence on a single buying date.
What does an over-hedge actually cost to unwind? +
You close the stranded portion of a rung as an FX swap marked to market. On £150k of surplus cover, a 3% adverse move is roughly £4,500, before the broker’s swap spread. A taper down the ladder keeps that number small by holding less cover on the least certain rung.
How much cash will a programme tie up, and can margin calls hit several tranches at once? +
A 5% deposit on £1.2m of hedged notional locks up about £60,000 until settlement. And yes: because the tranches sit on one book, a single sharp sterling rally can trigger margin calls across several of them together.
Can we change the ratio partway through the year? +
Yes. You adjust it with a roll or a close-out, each executed as an FX swap. The cost is the forward points for the change plus the broker’s bid-ask spread on the swap, not a penalty for changing your mind.
Should we use options or a collar instead of forwards? +
That is a different instrument decision, with an upfront premium in exchange for keeping your upside. We take it apart in our options versus forwards guide.
