Cross-Border Acquisition Currency Risk: Who Bears Exchange-Rate Changes Between Signing and Closing?

A fixed price can still leave the economics moving

A U.S. buyer agrees to pay €30 million for a European business. The seller has a fixed euro price. The buyer has a dollar funding requirement that changes until the euros are purchased or the exposure is hedged. A later exchange-rate move can therefore change the cash needed to close even though nobody changes the headline price.

There is no universal rule that the buyer or seller always absorbs currency movements. Start with the agreement: what amount is payable, in what currency, using what conversion convention? Then compare those obligations with each party’s funding and intended use of proceeds. The two parties can face different exposures on the same transaction.

Agreeing a fixed dollar purchase price transfers exchange-rate exposure to a seller that needs proceeds in another currency. Agreeing a fixed foreign-currency price leaves the buyer exposed to changes in its funding currency. Financing terms, closing conditions, and purchase-price adjustments determine the remaining exposure.

Identify the four currencies before comparing offers

Separate the currency in which the business earns money, the currency in which the purchase price is payable, the currency of acquisition funding, and the currency in which the seller plans to use the proceeds. A financial model expressed in dollars does not, by itself, make the legal payment obligation a dollar obligation.

A seller receiving the agreed euro amount has no purchase-price conversion shortfall merely because the buyer now needs more dollars. That seller can still have a later exposure if the proceeds will be converted into dollars. These are separate decisions and should have separate owners.

Worked example: a €30 million price and a $2.7 million funding change

Assume the equity cash consideration is fixed at €30 million, with no net-debt, working-capital, fee, tax, escrow, or other adjustments. The buyer funds in U.S. dollars and has not hedged. All exchange rates below are hypothetical scenario inputs, not current quotes or forecasts. USD per EUR means the dollars needed to buy one euro.

The calculation is €30 million multiplied by the applicable USD-per-EUR rate. At 1.17, the seller still receives €30 million and the buyer needs $2.7 million more than in the signing reference case. The price has not increased in euros; the dollar cost of satisfying it has increased by 8.33%.

Now assume the buyer has a fixed $21.6 million debt commitment and funds the balance with equity. At 1.08, equity is $10.8 million. At 1.17, equity becomes $13.5 million. The 8.33% increase in total dollar funding produces a 25% increase in the equity requirement. That is why an apparently modest currency sensitivity can become a serious sponsor funding issue.

If instead €20 million of committed acquisition debt is available to pay the euro consideration, the immediate unhedged purchase-price funding gap is €10 million. Its dollar cost changes from $10.8 million to $11.7 million across those two rates. The euro debt reduces the conversion needed at closing, but future euro interest and principal still require cash. Whether that debt matches the acquired business’s cash generation needs a separate assessment.

What changes when the seller accepts a fixed dollar price?

Keep the same initial economics but change the agreement: the seller accepts a fixed $32.4 million instead of €30 million. At a reference rate of 1.08 dollars per euro, those amounts are equivalent. At closing, if the euro has strengthened to 1.17, converting $32.4 million yields approximately €27.69 million.

Here the dollar-funded buyer’s base payment stays fixed, while a seller intending to retain euros receives approximately €2.31 million less than the €30 million reference amount. The calculation is $32.4 million divided by 1.17. The percentage effect differs from the earlier dollar calculation because the denominator and direction of conversion differ.

A seller evaluating a foreign-currency offer should specify the currency in which personal liquidity objectives are measured. If the intended use of proceeds is in dollars, a fixed dollar offer may be a useful match. If it is in euros, the same offer creates a conversion decision. Nationality alone does not answer the question.

The agreement needs an explicit conversion convention

A phrase such as “€30 million or its dollar equivalent” leaves important questions unless the remaining provisions answer them. Which party chooses the payment currency? Which rate source, observation time, business day, and direction of quotation apply? Is the amount measured at signing, at the estimated closing statement, or when funds are actually delivered?

Ask transaction counsel to reconcile those provisions with the financial model. Identify who bears transfer fees, conversion spreads, rounding differences, unavailable rate publications, and a payment delayed beyond the agreed date. A shared spreadsheet convention is insufficient if the signed documents use a different rule.

Where the parties deliberately negotiate a currency collar or sharing formula, model its endpoints and behavior beyond them. A purchase-price collar is a contractual allocation between buyer and seller; it is distinct from an option collar purchased from a bank. Neither term should substitute for the actual calculation.

Compare hedges by the obligation they create

A forward fixes a rate for an agreed currency amount and settlement date. A purchased currency option provides a contractual right subject to its strike, expiry, exercise, and premium terms. Same-currency funding can offset a purchase-price conversion requirement if it is legally available to the paying entity at the right time.

A forward is a firm commitment. A window forward allows delivery within a specified period, while options and collars have different costs and payoff terms. Ask the provider to show what you would pay under several exchange-rate and closing-date scenarios.

Do not label the difference between a forward quote and today’s spot rate as a standalone “hedging fee.” Compare quotes for the same notional, tenor, settlement terms, collateral requirements, and contingent features. Ask the bank to explain the components of its quoted price and the cash obligations under each scenario.

The failed-deal test matters as much as the closing-day rate

Suppose a buyer separately contracts to buy €30 million at an illustrative 1.095 dollars per euro. The dollar obligation is $32.85 million. If the acquisition closes, that covered amount is predictable. But a conventional forward does not disappear simply because the buyer no longer wants to acquire the business.

For a simplified failed-deal example, assume the acquisition has terminated and the forward reaches its contracted settlement date when spot is 1.02. Buying the euros costs $32.85 million while their spot value is $30.6 million: a $2.25 million adverse difference, ignoring spreads and other terms. An earlier unwind would instead be valued using the remaining contract terms and market pricing at that time; it should not be estimated by mechanically applying this maturity-date example.

Early termination or changes to a hedge can require a payment. Check whether its amount, currency, and maturity match the acquisition payment, and budget for any collateral and settlement requirements.

Deal-contingent hedging requires the same definition of completion

A deal-contingent hedge can remove the market-value settlement on non-completion if the transaction meets the agreed conditions. The price includes the cost of that protection. Availability and pricing depend on the deal, including its likelihood of completion, timing, size, and currency volatility.

The team must read the actual contingency language. Does the protected acquisition include the exact legal buyer, target, transaction structure, and consideration? What happens if closing is partial, the acquisition vehicle changes, the price is reduced, the outside date moves, or a terminated deal is later revived?

Match the hedge’s completion conditions and expiry date to the acquisition agreement and financing commitments. A hedge that expires before a permitted closing, or defines completion differently, can leave the buyer exposed.

Ask for written scenario outcomes covering on-time closing, delayed closing, reduced consideration, termination, and a revised transaction. Identify any payment or notice obligations that survive. The intended commercial protection and the executed documentation need to tell the same story.

Build the exposure from the funds flow, payment by payment

The enterprise-value headline is rarely the amount that a single entity must exchange on one date. Build a schedule of estimated seller cash proceeds, debt payoffs, transaction expenses, escrow deposits, deferred payments, and later adjustments. Record payer, recipient, amount, currency, expected date, and whether the amount is fixed or contingent.

A €30 million headline value should not automatically produce a €30 million hedge. For example, a separate €2 million debt repayment may also require euros, while €3 million held back for a later payment may not require euros at closing. Whether those amounts are inside or outside the stated price is a transaction-model question. Reconcile the schedule before executing anything.

Confirm that the entity making the acquisition payment can access the required cash on closing day. Cash held elsewhere in the group may need to be transferred or converted first. Assign an owner and deadline to each funding step.

Deferred consideration, earnouts, and escrow releases can create additional currency exposures after ownership transfers. The parties should specify the currency and calculation date for each payment, then address the uncertain amount and timing with their advisers. A hedge for the closing payment does not automatically protect those later proceeds.

The signing-to-closing currency checklist

The CFO should own the consolidated exposure schedule. Counsel should confirm the payment and contingency language. The lender and FX provider should confirm funding and instrument terms. The owner or board should approve the risk tolerance and funding buffer. This is a coordination task with identifiable decisions, rather than a last-minute bank conversion request.

Questions founders ask about acquisition currency risk

Put currency allocation into the deal model before signing

For a founder, the useful question is how much spendable value the offer delivers in the intended currency. For a buyer, it is how much committed funding and additional equity are needed across the closing scenarios. Both questions should be answered before the exchange rate becomes a negotiation surprise.
