Exchange Rates Explained: What Makes Currencies Move?
Learn what an exchange rate is and the major economic factors that can influence currency values.
Overview
An exchange rate tells you how much of one currency is needed to obtain a unit of another currency. For example, a USD/EUR quote can be used to estimate how many euros correspond to a given number of US dollars. Rates change over time as supply, demand, economic expectations, and monetary policy change.
How it works
When comparing exchange rates, check whether you are looking at a mid-market reference rate or a retail rate. A bank, card issuer, or transfer provider may apply a spread or separate fee, so the final amount can differ from the headline market quote.
Use the relevant GlobalConvert tool
Use the GlobalConvert converter to calculate the reference conversion, then compare the result with the actual provider quote when making a payment or transfer.
Important considerations
- Rates can change between the time you view a quote and the time a transaction is completed.
- Bank, card and transfer providers may apply spreads or fees that differ from the provider’s displayed rate.
- Historical performance does not guarantee future results.
