FX spread
An FX spread is the difference between the rate at which a currency can be bought (the ask price) and the rate at which it can be sold (the bid price). It is the primary revenue mechanism for FX providers and the primary cost component for businesses converting currencies in cross-border payments.
In FX markets, there is always a two-sided price: banks and FX providers buy currency at a lower rate (bid) than they sell it (ask). The spread between these two rates is how FX providers make money. A EUR/USD bid of 1.0800 and ask of 1.0810 represents a 10-pip spread. The provider buys EUR at 1.0800 and sells at 1.0810, earning the spread on each transaction.
For businesses converting currencies for cross-border payments, the FX spread is a direct cost. A company converting $1M to EUR at a 0.5% spread pays $5,000 more than it would at the interbank mid-rate. Across $50M in annual FX conversions, a 0.5% spread costs $250,000 a year. Comparing spread markups across providers is a material business decision.
FX spreads vary significantly by currency pair and provider. Major pairs (EUR/USD, GBP/USD, USD/JPY) have narrow spreads. Exotic emerging market pairs (NGN, BDT, PKR) have wider spreads, often 1–3% or more. Providers with deeper liquidity relationships can offer narrower spreads than those sourcing from thinner markets.
FX spread is the largest single cost component in most cross-border payment programs. Businesses that accept the FX rate quoted without benchmarking against alternatives routinely pay 1–3% more than necessary. For businesses with significant FX conversion volumes, rigorous FX pricing management is essential. Even small spread reductions generate material savings at scale.
- FX spreads are not always disclosed explicitly; they are embedded in the rate offered rather than quoted as a separate fee
- Comparing spreads requires knowing the interbank mid-rate at the time of conversion
- Spread quotes may not include all fees, so additional transfer fees or currency conversion surcharges may apply
- Exotic pair spreads may be unavoidably wide due to limited market liquidity
- Spot rate spreads differ from forward contract spreads, so hedging costs must be evaluated separately
A B2B platform processing $80M annually in cross-border payments benchmarks its bank's FX spreads against market alternatives. Analysis reveals its bank charges an average 1.8% spread across its corridor mix. Negotiating a new FX arrangement with Nium at an average 0.6% spread saves $960,000 annually.

Answers you didn't know you needed.
What is the difference between FX spread and FX margin?
FX spread is the bid-ask difference in market pricing. FX margin is the markup a provider adds above their own sourcing cost. In practice, both refer to the difference between the rate paid and the interbank mid-rate.
How do I calculate the FX spread I'm being charged?
Compare the rate you received against the interbank mid-rate at the same time (from Bloomberg, Reuters, or Google). The percentage difference is your effective FX spread.
Why are emerging market FX spreads wider?
Emerging market currencies have thinner liquidity, with fewer willing buyers and sellers at any given moment. Wider spreads reflect the cost and difficulty of sourcing these currencies in the market.
Can FX spreads be negotiated?
Yes, particularly for larger volumes. FX providers with multiple liquidity sources can offer tighter spreads for clients with significant conversion volume.
How does Nium price FX conversions?
