What You Should Know About Foreign Currency Exchange

Learn how currency exchange works and how bunq makes paying abroad simple, transparent, and instant.

Why understanding currency exchange matters

Every time you travel, shop online, or send money abroad, you use currency exchange. Knowing how it works helps you make smarter choices and avoid paying more than you need to. It’s a small thing that can make a big difference when it comes to how far your money goes.

What is currency exchange

Most countries have their own currency, while many in the EU share the euro. When you visit or move abroad, you need to convert your money into the local one. That’s currency exchange in action.

Banks and exchange offices handle this by trading currencies at rates that shift throughout the day. How much you get depends on how strong one currency is compared to another at that moment.

How exchange rates work

An exchange rate shows how much one currency is worth in another. It changes constantly based on global markets. The rate you see in the morning might not be the same one you’d get later that day.

Because of these changes, exchanging money before you travel can be risky. You might lock in a weaker rate without knowing it.

The problem with exchange fees

Traditional banks and exchange services often add extra fees or hide markups in their rates. That means you get less of the foreign currency than the headline rate suggests.

These hidden costs can add up quickly, especially if you travel often or make regular purchases abroad. Even a small difference in rate can quietly eat into your balance over time.

Why timing matters

If a bank or exchange office runs out of the currency you need, you might have to wait for a restock. By the time they’re ready, rates could change again and cost you more.

Digital banking removes that hassle. You can exchange instantly at the current rate, without worrying about stock, timing, or physical cash.

How bunq makes it easy

With ZeroFX, you can spend anywhere in the world without delays or hidden costs. Every time you pay abroad, bunq automatically applies the real Mastercard exchange rate, plus a small 0.5% adjustment* to reflect normal market movement.

You always get a fair, transparent rate that matches real market conditions. Exchange only what you need, when you need it.

You can also hold multiple currencies in your bunq account, such as euros, pounds, or dollars. When you pay in a country that uses one of those currencies, bunq automatically takes the payment from that balance. No conversion, no surprises.

Clear and transparent

Every transaction in the bunq app shows exactly which rate was used and how much was exchanged. You see it instantly, so there’s no confusion later.

Transparency is built into how bunq works. You don’t need to study markets or do any math to understand your exchange. You always see the rate, confirm the payment, and stay in control.

Why it matters

Even small hidden markups can take away from what you could be saving or spending elsewhere. By using the Mastercard exchange rate and showing every detail clearly, bunq helps you keep more of your money.

Our approach is simple. We stay digital, remove unnecessary steps, and keep everything transparent. You always know where your money goes and how much you’re really getting.
