Understanding how bank partnerships affect exchange rates can help save you money.
Currency exchange myths cost travelers billions each year in unnecessary fees and poor exchange rates. While conventional wisdom suggests avoiding airport kiosks and always paying in local currency, the reality in 2025 looks different.
From automated exchange systems offering competitive rates to evolving bank partnerships affecting ATM fees, many long-held beliefs about getting the best deal on foreign currency no longer apply.
Some misconceptions about currency exchange have never been accurate, while others have evolved over time. Here are some of the most common beliefs that deserve a closer look.
Airport currency exchanges have long had a reputation as the most expensive option for travelers. While traditional airport kiosks still charge premiums of 8–10 percent above market rates, major hubs now offer automated exchange systems that beat many bank rates.
At London’s Heathrow and Frankfurt’s terminals, new digital kiosks provide rates within 2–3 percent of interbank rates — significantly better than the 5–7 percent markup at traditional exchange counters.
The key difference? Operating costs. Automated systems handle thousands of transactions daily with minimal overhead, allowing airports to offer more competitive rates.
That helpful prompt at European card terminals asking if you’d like to pay in dollars? It’s actually costing you money. Dynamic currency conversion adds 3–4 percent to every transaction, despite showing you the “exact” amount in dollars. Major retailers and hotels particularly push this option, but declining it saves you real money on every purchase.
A quick coffee and pastry for €8 jumps from about $8.60 to $8.90 when choosing dollars instead of euros. Small differences add up across a trip, especially at hotels and restaurants where this option appears most frequently.
Pre-ordering currency from your bank used to be standard travel advice. In 2025, ATM networks and digital payments have changed this calculation. While getting some starter cash makes sense — enough for a taxi and first meal — carrying large amounts of foreign currency rarely does.
