# FX Margin

The FX margin is the difference between the exchange rate a bank, card, remittance company or payment provider gives its customer and the wholesale (interbank or mid-market) rate at which it obtains the currency — expressed as a percentage, and usually larger than the fee the customer is shown. It is the main revenue of remittance and travel-money businesses, a meaningful line for neobanks and acquirers, and the reason "no fee" international payments are not free.

**Also known as:** FX spread, Exchange-rate margin, FX mark-up

## Key facts

- **Used at:** every currency conversion a customer does not make on a trading desk — card payments abroad, international transfers, remittances, travel money, DCC at terminals, multi-currency accounts, marketplace payouts in foreign currency
- **Binding:** disclosure rules — the EU's cross-border payments regulation requires card and transfer providers to show the mark-up against the ECB reference rate; the UK's FCA has similar expectations; otherwise the margin is a commercial term rarely stated as one
- **Typical levels:** 0.35–1% at the fintechs that built their brand on it (Wise, Revolut's weekday rates); 2–3% on a bank's card abroad or an international transfer; 3–7% on DCC and at airport bureaux; the scheme's own conversion for a card transaction is close to wholesale, and the issuer's mark-up is what varies
- **Typical arithmetic:** on a $10,000 transfer at a rate 2.5% off mid-market, the customer loses $250 in the rate and may also pay a $25 "fee" — the fee is a tenth of the cost and the only number disclosed prominently
- **Parties:** the customer, the provider setting the rate, the wholesale market and the provider's treasury behind it, and the regulators requiring the margin to be shown

## How the FX margin works in practice

A customer sends €10,000 to the US. Her bank quotes "no fee" and a rate of 1.0450 when the mid-market rate is 1.0720: she receives $10,450 instead of $10,720 — a 2.5% margin, €270, in a transaction the bank described as free. A fintech quotes the mid-market rate and a 0.45% fee: €45. The difference, €225, is the FX margin, and it is where the international payments industry's revenue sits: remittance companies earn most of their money in the rate, not the fee; travel-money bureaux almost all of it; neobanks a growing share as customers spend abroad on their cards.

The market changed when the margin became visible. Wise built a company on showing the mid-market rate and charging a stated fee; the EU required, from 2020, that card issuers and transfer providers show the mark-up against the ECB rate; comparison sites and the fintechs' marketing did the rest. Margins fell at the visible end and held where customers do not look — DCC, bank transfers by people who trust their bank, corporate payments run by a treasury that never checked. Providers' treasuries manage the position between: they buy currency wholesale, hold balances in each currency, and hedge the exposure, so the margin is a spread over their own cost, which is near zero for the large ones.

For a buyer of a payments or remittance business, the FX margin by corridor and product is the revenue line to test for durability: what disclosure would do to it, and what a competitor at 0.5% would do to the customers who have not yet compared.

## Example

A neobank's customers spend €2bn a year abroad on its cards. It applies the scheme's rate plus a 1% margin on weekdays (2% at weekends, when the wholesale market is closed and the bank is exposed): €24m of FX revenue on a product marketed as "no foreign-transaction fees", which is true of the fee and not of the rate. A regulator's review under the disclosure rules finds the mark-up shown in the app's transaction detail and not at the point of decision; the neobank adds it to the notification sent at the moment of the tap. Spending abroad falls 3% and the margin's revenue 5%; customers' complaints fall by more; the neobank's marketing changes from "no fees" to "the real rate plus 1%", which converts better with the customers who compare.

## Common mistakes

- Comparing providers on the fee and never on the rate.
- "No fee" products where the entire cost is in the margin, and a regulator that reads the marketing.
- Corporate treasuries paying 2% on €50m of annual payments because nobody asked for a quote.
- Weekend margins undisclosed at the point of payment.
- Buyers of a remittance or card business valuing FX revenue that a comparison site could halve.
