TL;DR Key takeaways
- Compare quotes for the same amount, funding method and delivery date.
- Check the total amount you pay and what the recipient can use after charges.
- Use market benchmarks to question the rate, then judge any premium against the delivery commitments your business needs.
An FX quote is worth questioning when its total cost is higher than an available alternative. But the difference alone does not establish that it is unfair. The useful question is whether you are paying more for the same payment—or buying a commitment the cheaper quote does not include.
Start with what your supplier must receive and by when. Compare the full cost of achieving that outcome, then ask the more expensive provider to explain the remaining premium in concrete terms. “Better service” is not enough unless you can identify the benefit your business can use.
Make the competing quotes cover the same obligation
Give each provider the same currencies, direction, transaction amount, funding method, FX value date and required recipient-availability time. For a fixed invoice, ask for the total sender debit needed to deliver the invoice in full. For a fixed spending budget, compare net recipient proceeds with fees included inside that budget.
Request quotes close enough in time to avoid mistaking market movement for a provider price difference. Record whether the rate is firm or indicative, how long it remains available and what conditions secure it. An expired price or an offer requiring a funding deadline you cannot meet is not an available substitute.
The FX Global Code calls for clarity about firm versus indicative prices and transaction terms. It describes good practice in the wholesale FX market; it does not impose legal or regulatory obligations or set a universal acceptable markup. Use it to sharpen your questions, rather than treating a price difference as a legal verdict.
Calculate the difference you are actually being asked to pay
Consider a hypothetical €100,000 supplier invoice funded from pounds. Both offers are available at the same time, require the same funding and deliver the full €100,000 on the same terms, without recipient deductions:
- Quote A: €1.2500 per £1, plus a £250 fee. Conversion costs £80,000, so the full debit is £80,250.
- Quote B: €1.2480 per £1, with no separate fee. The full debit is £80,128.21, rounded to the nearest penny.
Quote A’s better exchange rate still produces a bill £121.79 higher. Because these offers cover the same outcome, that is the amount to challenge. Ask whether the provider can match the lower full debit or identify an additional commitment relevant to your payment. Do not add an estimated benchmark markup to either total: its effect is already inside the conversion price.
The no-deduction assumption matters. If €100,000 is merely the amount sent, a recipient-bank charge could leave the invoice partly unpaid. Establish who bears such charges and whether the provider commits to the net receipt. An unknown deduction is an unresolved comparison, not a zero-cost item.
A premium needs a specific commitment
Now change the hypothetical terms. Quote B’s £80,128.21 covers a payment with expected supplier availability tomorrow. Quote A’s £80,250 includes a written commitment to the full receipt by the supplier’s deadline, conditional on cleared funding and all release conditions being satisfied by a specified cutoff. All other terms remain the same.
The £121.79 difference now buys a defined delivery commitment, if its conditions and remedy are useful. Read what happens if the deadline is missed, which exclusions apply and whether the promise covers recipient availability or only sending the payment. A firm FX rate protects a conversion price; it does not automatically protect the delivery date.
Suppose the supplier has a documented £600-equivalent charge if cleared funds miss that deadline. The premium is about 20.3% of that charge. In a simplified decision where the commitment fully prevents this particular cost, the break-even probability of incurring it with the cheaper route is £121.79 ÷ £600, or approximately 20.3%. That is a hypothetical decision threshold, not an estimate of any provider’s reliability.
You still need evidence about the actual route and the commitment’s limits before using that threshold. If the deadline is flexible, the charge would be waived, or the more expensive provider has the same exclusions, the supposed advantage may disappear. If both providers offer the same written commitment, the comparison returns to the £121.79 price difference for equivalent terms.
A benchmark gap starts a question; it does not settle fairness
A relevant market reference helps test the explanation for the conversion price. Match the pair, direction, observation time and value date. Ask which part of the quoted amount is embedded in the rate, which charges are separate, and whether the premium changes with the amount or funding arrangement.
A midpoint is a measuring point, not a firm offer your business is guaranteed to obtain. The ECB’s euro reference rates, for example, are informational and are discouraged for transactions. An offer farther from that reference may cost more, but the gap alone does not reveal the provider’s internal costs or profit.
A useful challenge is therefore specific: “Your total debit is £121.79 above this executable alternative for the same net receipt. Which commitment explains the difference?” A response about unspecified liquidity, technology or service quality does not establish value for this particular transaction.
Accept, renegotiate or resolve the missing term
Separate three outcomes. If both offers meet the obligation on equivalent workable terms, compare their full debits. If one offers a useful additional commitment, decide whether its price fits the business consequence it addresses. If receipt, timing or funding terms remain unclear, obtain a revised quote before treating the offers as comparable.
Keep the accepted quote and its conditions for reconciliation against the actual debit, recipient receipt and delivery outcome. A later difference may identify a fee, missed condition or delivery issue worth challenging. It does not establish the cause until those records are checked.
Conclusion
Judge an FX quote on the cost of the payment you can actually buy, then make any premium earn its place through a useful, identifiable commitment. Comparable executable offers and clear terms support a stronger pricing challenge than a benchmark percentage alone.
