How much of your FX exposure should you hedge?

TL;DR: A strong hedging policy doesn't apply the same cover to every exposure. It tapers coverage by time horizon, hedging more of what's certain and near-term and less of what's further out and less certain, so you're protected where you need to be without over-committing to a forecast that might not hold. Bound can run that tapered profile for you through whichever combination of its Forwarding, Averaging and Ranging programmes fits each horizon, with every fee disclosed upfront. And because plans change, you can amend the date or amount on any trade yourself, directly in the platform.

Most treasury teams reach the same sticking point. The board has agreed that the business needs to hedge its foreign currency exposure. The policy framework has been approved. And then someone asks: what percentage? The honest answer is that the right ratio depends on forecast confidence and time horizon, and shifts as both change over time. That's correct, but it's rarely satisfying when a governance committee is waiting for a number.

Forward contracts on Bound can be amended up to the settlement date. If a payment date shifts or the amount changes, you adjust it in the platform and see the fee on screen before confirming. That means the ratio you start with doesn't need to be exact. It can be updated as your forecasts firm up.This piece covers how the ratio is calculated, the principle that it should reflect your level of forecast confidence, and how to structure it across different time horizons so that coverage tapers as certainty falls.

Whether your business should be actively hedging its cash flow exposure at all is a separate question, covered in Bound's cash flow hedging guide. This piece starts from the assumption that a decision has been made.

The hedge ratio decision

The hedge ratio represents the proportion of an identified foreign currency exposure that is covered by a hedging instrument. Before you can apply a ratio defensibly, you need to be precise about which type of exposure you are hedging, because each type carries different certainty and calls for a different treatment:

• Transactional exposure: Risk arising between contracting in a foreign currency and settling the transaction, typically under twelve months. It covers both payables (import invoices, purchase orders) and receivables (export invoices, contracted international revenue), as well as financing events such as foreign-currency funding rounds or venture debt drawdowns where the settlement amount in the base currency is exposed to rate movement before funds are received or repaid.

• Translational exposure: Accounting risk from consolidating a foreign subsidiary's financial statements into the parent company's base currency, a balance sheet consideration rather than a cash flow one.

• Economic exposure: Long-term structural risk that exchange rate shifts will erode a company's market value or competitive positioning over time, the hardest to quantify and the longest-dated.

Each of those three exposure types calls for a different ratio approach. The ratio you set for a specific transactional exposure, an import payable settling in ninety days, won't be the same ratio you apply to a budget-level economic exposure stretching eighteen months out. The maths behind each is different.

How the hedge ratio is calculated

For most transactional hedging, where a forward directly matches the currency pair and approximate settlement date of the underlying invoice, the hedge ratio is the notional value of hedges divided by the total value of the exposure.

Why the ratio is rarely 100%

The over-hedging risk carries direct operational consequences, two of which matter most in practice. If a company hedges more than its actual exposure, it can't draw down the full hedged notional (see glossary) against a real transaction, and the excess has to be closed out or rolled forward (see glossary). Closing a position early on Bound is at Bound's discretion. When a position is closed early, the mark-to-market amount on that portion is typically settled. If the market has moved in the business's favour since booking, that produces a gain that may be returned to the business. If it has moved against, it produces a cost. The outcome isn't predictable at the point of booking, so unwinding an excess position carries uncertainty in both directions.

Working capital cost compounds the over-hedging risk. Under traditional broker and bank models, forward contracts typically require an upfront margin deposit of 5% to 10% of contract value. Bound's forward contracts are available with no margin deposit, which means no upfront margin deposit is required against open trades and frees the working capital that would otherwise sit against open trades. The trade-off is a higher spread than hedging with a 5% margin deposit, and that spread is disclosed before any position is confirmed. The margin deposit arrangement typically operates under a Title Transfer Collateral Arrangement, which is not available to retail clients, and the exact terms are agreed at account setup. Running a 100% ratio is defensible only where settlement dates are contractually fixed and your customer has no history of requesting extensions. At any other horizon, the over-hedge risk and the close-out mechanics described above apply.

Running no hedge means carrying FX risk on your P&L. As Bound's guide on euro revenue impact shows, the P&L effect can be material. The ratio you can defend sits between those poles, determined by your confidence in the underlying cash flow.

Match your hedge ratio to forecast confidence

The clearest way to see this principle in action is to compare a contracted cash flow with a projected one. The principle is straightforward: the hedge ratio can be proportional to your certainty about the underlying cash flow. High certainty supports a high ratio. Low certainty supports a lower one.

Contracted cash flows vs. forecast projections

A signed purchase order settling in sixty days in USD and a sales forecast showing USD revenue arriving in the next fiscal year are both FX exposures, but only the first is certain. As Bound's FX risk management guide covers, transactional exposure arising from a signed contract is traceable to a specific notional, a specific currency, and an approximate settlement date, typically settling within twelve months. A budget projection for the same currency over the same horizon, built on historical averages rather than signed contracts, carries genuine uncertainty about whether the cash flow arrives at all.

How data freshness affects the hedge ratio

Stale exposure data can break the connection between the hedge ratio and reality. If the exposure figure driving your hedges comes from a spreadsheet export that runs weekly, the ratio you apply to it is correct at export date and generally drifts from that point until the next pull. This is the structural misalignment that can force unplanned spot trades when actual payment timing diverges from forecast.

Bound integrates with accounting software, payment platforms, bank feeds and spreadsheets to calculate FX exposure from current payables and receivables, so the ratio you set in policy is applied to exposure data reflecting your current invoices rather than your last CSV export.

Contracted commitments carry higher hedge ratios

A signed contract removes the largest source of uncertainty from the hedge ratio decision. The timing may shift slightly, and the amount may see small adjustments, but the core notional is committed. That justifies a higher ratio for most treasury policies, because the probability of ending up over-hedged is low.

Why your hedge ratio can taper by tenor

The tenor taper (see glossary) is where a formally structured hedging programme separates itself from a static percentage applied across all horizons. Bound offers three programmes designed for different levels of forecast certainty. This means the business does not have to choose one fixed percentage to hedge before it knows exactly how much it will need to pay or receive. Across all three programmes, amounts and dates can be adjusted before settlement as forecasts become more certain.

A layered hedging programme, the market term for splitting an exposure into pieces executed over time, is what Bound automates as its Averaging programme, booking a portion automatically every day across the programme rather than at times a broker judges or a customer calls in, which suits a business that wants a blended rate.

A Forwarding position locks a fixed rate and settlement date against a known notional, which suits the higher-certainty bands below. A Ranging position incorporates a stop and a limit so the executed rate stays inside a band rather than locking a single rate today, with a trailing stop that can improve the worst-case rate if the market moves in the business's favour, which suits exposure where the business wants some protection without committing the full notional at one point in time.

Why certainty falls as the horizon extends

Certainty is highest in the 0-3 month band, where purchase orders are issued, invoices are raised, and settlement dates are contractually fixed. It erodes progressively from there. Operational plans at 3-6 months are confirmed but carry timing and volume variation that contracted commitments at this horizon commonly experience as payment dates shift or order sizes change. Budget projections at 6-12 months depend on assumptions about pipeline conversion and business performance that events haven't yet tested. Beyond twelve months, exposure is no longer tied to specific invoices or purchase orders. At this horizon you are managing the broader effect of sustained exchange rate movements on the business's costs, revenues and competitive position rather than matching a hedge to a known payment. A Ranging position can be a better fit than a full forward lock at this horizon because it sets a stop and a limit rather than committing the full notional at a single rate. The illustrative ratio ranges in the table below translate that decay into starting points for each horizon band.

What a tapered profile looks like in practice

The tapered profile applies a different ratio at each horizon and reduces the notional hedged as the forecast becomes less reliable. Because payment dates inevitably shift, the operational requirement alongside the ratio structure is the ability to amend FX contracts without costs that weren't budgeted for at booking.

Bound's amendment workflow addresses this directly. When a payment date shifts, you change the settlement date yourself in-platform without calling or emailing a broker, which means the adjustment happens immediately rather than when a counterparty picks up the phone. The fee for that change is disclosed on screen before you confirm it, and the full amendment schedule is published upfront rather than disclosed on request, so the cost of adjusting a position is calculable in advance rather than a negotiation when payment dates shift at month-end.

Traditional brokers typically don't offer self-serve amendments and don't disclose the cost of an amendment before the trade is booked, leaving you to discover both the process and the cost at the point of need. The structural difference matters when you're running a tapered programme across multiple horizon bands simultaneously.

Illustrative hedge ratio ranges by horizon

The section above describes the principle, the table below translates it into starting points for policy design, not recommendations. They reflect the principle of matching ratio to forecast confidence and should be adapted to the specific business model, currency volatility, and board risk appetite. They're illustrative, and your programme's actual parameters will depend on your exposure profile and governance requirements.

Adapting ranges to your exposure profile

High-margin SaaS businesses with predictable contracted recurring revenue can support ratios at the higher end of each range because their cash flows are more reliable than those of a project-based exporter where deal timing is uncertain. Currency volatility also matters: a pair with materially higher historical volatility may warrant a more conservative ratio at equivalent tenors because the cost of being wrong on the forecast is proportionally higher.

Putting the ratio into your hedging policy

A ratio established but not documented is a recurring argument rather than a governance decision. The policy converts the ratio into an auditable commitment that the board has approved, the team can execute against, and auditors can review without requiring a verbal reconstruction of why each trade was booked.

Writing the ratio into policy language

Using the illustrative ranges above as a starting point, the policy clause should specify the ratio at each tenor band, which exposure types apply at the higher and lower end of each band, and what triggers an out-of-cycle review, a material forecast change or a material shift in the 30-day rolling volatility of the underlying currency pair.

Setting a review cadence

A quarterly review works for most programmes, covering the period when both macro conditions and business forecasts have had enough time to shift materially. The review doesn't require rebuilding the programme from scratch: it requires checking whether the ratio applied in the previous quarter still reflects forecast confidence at each horizon.

Out-of-cycle reviews are triggered by specific events rather than calendar dates. Encoding these trigger events in the policy means the review happens when it matters, regardless of who is running the programme.

Making the ratio auditable

An auditable hedging programme requires documentation at the trade level, not just at the policy level. The checklist covers three elements:

1. Documented rationale for every trade: each position linked to a specific forecast or contracted commitment, with the horizon tier and ratio band recorded at execution.

2. Mark-to-market positions on open trades: MTM positions on open trades are available to download on demand as PDF or CSV statements, giving you the valuation data auditors or investors may request without manual reconstruction.

3. Amendment history: every change to a settlement date, amount, or structure recorded with the disclosed fee and the rationale for the amendment. Bound's programme elements guide covers the platform controls in detail.

The combination of disclosed fees before execution, amendment history at the trade level, and MTM data available for download gives you the documentation trail required for board reporting, investor review, and audit without manual reconstruction after the fact.

Frequently asked questions

Should the hedge ratio be the same for all currencies?

No. Currency pairs with different volatility profiles and liquidity characteristics warrant different ratio considerations at equivalent tenors. Bound's in-house specialists can help you adjust ratios based on the specific currency pairs in your exposure profile.

How often should we review our hedge ratio?

Formally, quarterly, with out-of-cycle reviews triggered by a material change in the business forecast or a material shift in the 30-day rolling volatility of the underlying currency pair. The policy should specify both rather than leaving trigger events to judgement.

What if our exposure forecast changes after we hedge?

If the forecast drops below the hedged notional, you must adjust the position by executing an offsetting trade or amending FX contracts. More broadly, material changes warrant a ratio review rather than holding the position mechanically. These include a delayed payment, a lost contract, or a currency pair whose volatility has shifted the risk profile of the position. Bound allows you to split or decrease notionals, or change the settlement date on trades in-platform, with the fee disclosed before execution is confirmed, so mid-programme adjustments are calculable in advance rather than a negotiation at the point of need.

Key terms

Hedge ratio: The proportion of an identified foreign currency exposure that is covered by a hedging instrument. A hedge ratio of 80% means that 80% of the net exposure is hedged using a forward contract or similar instrument, while the remaining 20% is left unhedged. The policy should set the appropriate ratio for each type of exposure and explain the reasoning behind it.

Tenor taper: A hedging programme structure that applies a higher hedge ratio to near-term exposures, where forecast confidence is high, and progressively lower ratios to exposures at longer time horizons, where forecast confidence falls. The logic is that the certainty you have about a payment due in sixty days is materially higher than the certainty you have about revenue projected twelve months out. Applying the same ratio to both would either over-hedge the longer-dated exposure or under-hedge the near-term one. A tapered profile avoids both by matching the ratio to the reliability of the underlying forecast at each horizon band.

Transactional exposure: Short-term FX risk arising between contracting in a foreign currency and settling the transaction, typically under twelve months. Covers payables (import invoices, purchase orders), receivables (export invoices, contracted international revenue), and financing events such as foreign-currency funding rounds or venture debt drawdowns where the base-currency settlement amount is exposed to rate movement before the transaction completes.

Translational exposure: Accounting risk arising from the consolidation of a foreign subsidiary's financial statements into the parent company's base currency. It affects reported balance sheet values rather than operating cash flows, and is typically a consideration for businesses with overseas subsidiaries rather than for transactional hedging programmes.

Economic exposure: Long-term structural risk that sustained exchange rate movements will erode a company's market value or competitive positioning over time. It's the hardest of the three exposure types to quantify, the longest-dated, and the least directly addressed by transactional hedging instruments.

Mark-to-market (MTM): The valuation of an open position at current market rates against the rate it was booked at, which can be positive or negative to the customer. Bound reports MTM across its book nightly to its regulator as a regulatory obligation. For customers, MTM positions on open trades are downloadable on demand as PDF or CSV statements.

Notional amount: The face value of a forward contract, meaning the total currency amount the trade covers. For example, if a business books a forward to buy USD 500,000 at a fixed rate, the notional amount is USD 500,000. The notional is not the cost of the trade. It is the underlying amount the hedge is written against.

Roll forward: Extending the settlement date of an existing forward contract to a later date rather than closing the position at its original maturity. A roll forward is typically used when the underlying transaction has been delayed and the original settlement date no longer matches the expected payment date, but it is also the mechanism used to extend an over-hedged position when the excess cannot be matched against a real transaction in time. The cost of rolling forward is determined by the interest rate differential between the two currencies at the time of the roll, reflected in the forward points that apply to the new settlement date. On Bound, a roll forward is executed as a settlement date amendment in-platform, with the fee shown on screen before you confirm the change.
