Frequently Asked Questions
Why do exchange rates change?
Supply/demand for currencies, interest rates, inflation, economic growth, geopolitical events, central bank policy.
What's the difference between bid and ask rates?
Bid = rate banks buy currency (you sell). Ask = rate banks sell (you buy). Spread = profit margin.
Does timing matter when exchanging?
Absolutely. Currency moves daily/hourly. Poor timing costs 2-5% on international transfers. Lock rates when possible.
