FX margin
FX margin is the percentage markup that a payment provider, bank, or FX service adds to the interbank exchange rate. It is the provider's revenue on a currency conversion, and the buyer's cost above the wholesale rate available with institutional market access.
The interbank exchange rate is the rate at which large financial institutions trade currencies with each other. It is the wholesale rate unavailable to most businesses. Payment providers and banks source FX at or near the interbank rate and add a margin when selling to clients. The margin covers the provider's FX risk management costs, infrastructure, and profit.
FX margin is typically expressed as a percentage or in pips (0.01% of the exchange rate). A provider offering USD/EUR at 1.0790 when the interbank rate is 1.0810 has applied a 20-pip margin, approximately 0.19% of the transaction value.
FX margins vary significantly across provider types. Retail banks routinely charge 3–5% FX margin. Consumer FX apps (Wise, Revolut) have reduced this to 0.5–1.5% for retail customers. Institutional payment providers like Nium offer corporate clients 0.1–0.5% margins for major currency pairs, and 0.5–2% for emerging market pairs, depending on volume.
FX margin is a direct, recurring cost for any business converting currencies for cross-border operations. Businesses with significant FX needs, including international payroll, global supplier payments, and marketplace payouts, face a cumulative annual cost from FX margin that can be a material expense. Benchmarking and negotiating FX margins is one of the highest-ROI treasury management activities.
- FX margin is often not disclosed as a separate line item; it is embedded in the rate offered
- Comparing margins requires accessing the interbank mid-rate at the exact time of comparison
- Some providers quote low margins but charge additional fees that increase the effective cost
- FX margin for emerging market pairs is inherently higher due to liquidity costs
- Forward FX margins are different from spot margins and require separate evaluation

Is the FX margin the same as the FX spread?
