Exchange rates are reference points, not offers. This guide explains the forces behind the numbers you see.
The Anatomy of FX Exchange Markup
When you send money overseas or pay with a credit card abroad, financial institutions generate revenue through two main mechanisms: explicit fees (upfront transfer fees) and implicit fees (the FX spread markup).
The FX spread is calculated as: `((Provider Offered Rate - Mid-Market Rate) / Mid-Market Rate) * 100`. Even a small 2% spread on a $5,000 transfer equals a hidden $100 charge.
Traditional Banks vs Modern Money Transfer Operators (MTOs)
Traditional high-street banks often charge both a fixed wire fee ($25–$45) and a wide currency markup (2%–4%). Modern digital fintech platforms leverage direct local bank network integration to offer rates within 0.2%–0.8% of the interbank rate.
