A California company agrees to pay a foreign supplier €100,000 in three months. Before payment comes due, the euro rises against the dollar. The goods cost the same in euros, but the buyer now needs more dollars to pay the invoice. Who absorbs that difference? Usually, the answer starts with the contract’s payment terms. A currency clause in an international contract can assign exchange-rate risk, define conversion mechanics, and prevent disagreements about whether a payment actually satisfies the debt.
Start with the currency that defines the debt
The currency used to state the price is not always the currency used to make payment. Your contract should distinguish between the two. A price of €100,000 payable in euros generally leaves a buyer funding the purchase in dollars exposed to changes in the dollar cost of those euros. A fixed $110,000 price shifts that particular conversion exposure to a seller whose expenses are in euros.
If the agreement permits payment in either currency, it needs a conversion rule. Otherwise, each side may calculate a different amount and believe its calculation is correct.
California Civil Code § 1636 directs courts to interpret a contract to give effect to the parties’ mutual intention at the time of contracting, so far as that intention is ascertainable and lawful. Clear payment language helps establish that intention. It does not eliminate every dispute, particularly when purchase orders, invoices, and master agreements contain inconsistent terms.
Currency clause international contract checklist
A useful currency clause does more than name “dollars.” California businesses should identify the currency precisely and explain how payment works. The following points belong in the agreement, not just an accounting email:
- Price currency: State whether the debt is denominated in U.S. dollars, euros, or another identified currency. Currency codes such as USD and EUR reduce ambiguity.
- Payment currency: Specify whether payment must use the price currency or whether another currency is permitted.
- Exchange-rate source: Identify a published benchmark or other agreed source, including the relevant rate type.
- Conversion time: Define the applicable date, time, and time zone.
- Nonbusiness days: Explain which rate applies when the source does not publish a rate that day.
- Unavailable rates: Provide a fallback if the benchmark stops publishing or cannot be accessed.
- Rounding: State how the converted amount will be rounded.
The clause should also identify whether the rate includes a bank’s spread or conversion markup. A benchmark rate and the rate actually available from a bank may differ.
Choose who bears changes before payment
There is no single allocation that fits every transaction. The right structure depends on which party earns revenue, incurs expenses, or can obtain currency protection in the relevant market.
- Fixed foreign-currency price: The buyer owes a fixed foreign-currency amount, even if its cost in dollars rises.
- Fixed dollar price: The buyer’s dollar obligation stays constant, while the seller’s converted proceeds may change.
- Agreed conversion date: The parties lock the payment calculation to a specified date, rather than leaving it open until payment.
- Adjustment formula: The price changes when an identified exchange rate moves beyond a negotiated threshold.
An adjustment formula should explain whether it operates in both directions, how often adjustments occur, and whether increases or decreases are capped. If a sharp movement triggers renegotiation, specify what happens if negotiations fail. A duty to discuss pricing is not the same as an automatic price adjustment or a right to terminate.
Address late payments, fees, and refunds
A clause that works for an on-time payment may leave gaps when payment arrives late. If conversion occurs on the due date, the resulting payment amount may remain fixed despite later currency movements. If conversion occurs when payment is received, the amount can continue changing during the delay. State the intended rule and coordinate it with any interest or default provisions.
Also define when payment counts as received. Initiating a wire is different from the recipient receiving available funds. Sending-bank, intermediary-bank, and receiving-bank fees can leave the recipient short even when the sender transfers the invoice amount.
Address these related questions:
- Must the recipient receive the full stated amount after transfer fees?
- Which currency applies to refunds, credits, deposits, and partial payments?
- Does a refund return the original currency amount or its converted equivalent?
- How are payments allocated across invoices issued in different currencies?
Keep any contractual deduction restrictions separate from legally required withholding obligations.
Coordinate currency terms with the rest of the agreement
A currency clause does not replace governing-law, dispute-resolution, or payment-compliance provisions. Choosing California law does not make foreign exchange controls, banking restrictions, or applicable sanctions irrelevant. Nor does a contract’s chosen payment currency automatically determine how a court will express or enforce a judgment.
Review the clause alongside delivery terms, termination rights, tax provisions, and any provision addressing interrupted payments. If an alternative payment route is permitted, require a lawful method and explain whether it changes the currency obligation. Avoid giving either party unrestricted discretion to select a favorable exchange rate.
For recurring transactions, confirm that the master agreement controls over conflicting invoice language. An international business contract review can identify currency gaps before the parties commit to pricing. Businesses and individuals entering cross-border agreements should preserve the agreed terms, rate records, payment confirmations, and communications about any later changes.
