What is a fair currency spread?+
For major currency pairs like EUR/USD or GBP/USD, spreads of 0.01 to 0.05% are typical on forex platforms. Bank currency exchange spreads are typically 1-3%. Airport exchanges often charge 3-7%. Always compare spreads across providers to minimize conversion costs.
How can I get the best currency exchange rate?+
Use specialist FX platforms or multi-currency accounts (Wise, Revolut, etc.) which offer mid-market rates with low flat fees. Avoid airport exchanges and hotel front desks. For large amounts, negotiate directly with bank FX desks or use a licensed forex broker.
