Currency Exchange Tips: How to Get the Best Rate Every Time

Getting a bad exchange rate can cost you hundreds on a long trip. These proven tips help you get close to the interbank rate every time you exchange.

The gap between the interbank rate (what banks trade at between themselves) and the rate offered to consumers is where most exchange-related money is lost. A 2% spread on a £5,000 exchange means you lose £100 before doing anything. A 5% spread at an airport kiosk means £250 gone. Knowing how to find and achieve better rates is a practical financial skill.

The Worst Places to Exchange Money

• Airport currency exchange kiosks: typically 10–15% above mid-market rate
• Hotel front desks: 5–10% spread, highly convenient but very expensive
• Roadside exchange bureaux in tourist areas: often fraudulent rates or short-change
• Cruise ship exchanges: captive market pricing, among the worst available
• Dynamic Currency Conversion at ATMs: always choose local currency to avoid it

The Best Places to Exchange Money

• Wise card or Revolut: real mid-market rate with minimal spread
• Post Office (UK) and official bank branches: typically 1–2% spread
• Local bank ATMs using a fee-free card: usually close to interbank rate
• Pre-ordering currency online for collection: better rates than walk-in
• Crypto debit card: spend directly from USDC at interbank rate via Steyble

Timing Your Exchange

For large conversions — property purchase abroad, school fees, salary repatriation — currency timing matters. Exchange rates can move 5–10% over a few months. Setting a rate alert with Wise or Revolut costs nothing. For amounts above £10,000, a forward contract with OFX lets you lock in today's rate for delivery in 3–12 months, giving budget certainty.
