The difference between the market rate (or mid-market rate) and the rate provided by a financial institution or broker. This is essentially a fee added to the transaction by the provider.
Simple Example: If the mid-market rate for EUR/USD is 1.0950, but the bank provides an acquisition rate of 1.1050, the FX markup is the difference, which is 0.0100.

Mid-Market Rate: 1.0950
Acquisition Rate: 1.1050
FX Markup: 1.1050−1.0950=0.01001.1050 - 1.0950 = 0.01001.1050−1.0950=0.0100
