Making Your Money Go Further Overseas.
Travelling overseas is exciting, but managing your money in another currency can quickly become confusing, and expensive if you aren't prepared.
Whether you're planning a weekend getaway or a round-the-world adventure, understanding how currency conversion works can save you hundreds of dollars in unnecessary fees and poor exchange rates.
This guide explains everything you need to know about converting money while travelling, along with why we recommend the Wise Account and Wise Card for international travellers.
Travelling overseas is one of life's greatest adventures, but one thing catches many travellers by surprise—currency conversion.
The Complete Guide to Exchange Rates, Travel Money, and the Wise Card
The Complete Guide to Exchange Rates, Travel Money, and the Wise Card
Whether you're planning a holiday to Japan, a European adventure, a shopping trip to Singapore, or a tropical escape to Bali, understanding how foreign exchange works can save you a surprising amount of money.
Unfortunately, many travellers lose money before they even arrive at their destination. Poor exchange rates, hidden bank fees, airport currency kiosks, overseas transaction charges, and Dynamic Currency Conversion (DCC) can all quietly increase the cost of your trip.
The good news is that avoiding these unnecessary costs is easier than ever.
This guide explains everything you need to know about currency conversion in plain English. You'll learn how exchange rates work, where to exchange your money, how to avoid common mistakes, and why millions of travellers now use the Wise Account and Wise Card when travelling internationally.
Whether you're travelling for a weekend or embarking on a round-the-world adventure, this guide will help you make every dollar go further.
What is Currency Conversion?
What is Currency Conversion?
Currency conversion is the process of exchanging one country's money for another.
For example:
US Dollar (USD) → Japanese Yen (JPY)
New Zealand Dollar (NZD) → Euro (EUR)
British Pound (GBP) → Chinese Yuan (CNY)
Singapore Dollar (SGD) → Canadian Dollars (CAD)
Australian Dollar (AUD) → Thai Baht (THB)
The amount you receive depends on the exchange rate at the time of the conversion.
Exchange rates are constantly changing throughout the day as global financial markets react to economic news, inflation, interest rates, and supply and demand.
Because exchange rates move continually, the amount you receive today may be different tomorrow—or even an hour later.
Why Currency Conversion Matters
Why Currency Conversion Matters
When you exchange one currency for another, every fraction of a cent matters.
Imagine you're travelling from The United States to Japan with US$8,000 to spend.
If one provider offers an exchange rate that is only 2% worse than another, you could lose the equivalent of more than US$160 in spending power before you've even bought your first meal.
Now add:
Overseas card fees
ATM withdrawal charges
Currency conversion margins
Dynamic Currency Conversion
Suddenly your holiday could cost several hundred dollars more than necessary.
Most travellers spend months looking for cheap flights and hotel deals but only a few minutes thinking about how they'll pay once they arrive.
Choosing the right travel money solution can be just as important as finding the best airfare.
Mid-Market Rate vs Exchange Rate
Mid-Market Rate vs Exchange Rate
One of the most confusing parts of currency conversion is that there isn't just one exchange rate.
The mid-market rate (sometimes called the interbank rate) is the rate banks use when trading currencies with one another. It's the rate you'll often see reported on financial websites.
Most consumers don't receive this exact rate.
Banks, airport exchange counters, and many currency providers typically add a margin to the exchange rate or charge additional fees as part of the transaction.
This means the final amount you receive can vary significantly depending on who you use.
That's why it's important to compare the total cost of a currency exchange—not just the advertised rate.
How Exchange Rates Change
How Exchange Rates Change
Exchange rates can move every few seconds.
Some of the biggest influences include:
Interest rate decisions
Inflation
Political events
Economic growth
Global demand for currencies
International trade
Financial market confidence
For travellers, these daily fluctuations usually have only a modest effect on a holiday budget, but choosing a provider with transparent pricing can often make a much bigger difference than trying to "time the market."
The Biggest Mistakes Travellers Make
The Biggest Mistakes Travellers Make
1. Exchanging Money at the Airport
1. Exchanging Money at the Airport
Airport exchange counters are convenient, but convenience often comes at a cost.
They may charge:
Less competitive exchange rates
Service fees
Commission
Hidden margins
If possible, organise your travel money before leaving home or use a travel card designed for overseas spending.
2. Paying in Your Home Currency
2. Paying in Your Home Currency
When paying overseas, a payment terminal may ask:
"Would you like to pay in your home currency, for example: US Dollars?" Although this sounds helpful, it's usually not the best option. This is known as Dynamic Currency Conversion (DCC).
Instead of your own bank or travel card provider performing the conversion, the merchant's payment provider does it—often at a less favourable exchange rate. In most situations, choosing to pay in the local currency gives you a better outcome.
3. Carrying Too Much Cash
3. Carrying Too Much Cash
Cash is useful, but carrying large amounts increases the risk of loss or theft. Today, many destinations accept contactless card payments almost everywhere.
A combination of a travel card, a small amount of local currency, and a backup payment method is often the safest approach.

Comparing Your Travel Money Options
Comparing Your Travel Money Options
Not all ways of spending money overseas are created equal.
Some methods are convenient but expensive. Others offer competitive exchange rates but may have limitations or fees that aren't immediately obvious.
Understanding the strengths and weaknesses of each option will help you choose the right combination for your trip.
For most travellers, there isn't a single perfect solution. Instead, we recommend carrying a combination of a travel card, a backup payment card, and a small amount of local cash.

Frequently Asked Questions
Frequently Asked Questions
Is Wise cheaper than a bank?

Do I still need cash?
In many destinations, cards are widely accepted. However, carrying a modest amount of local cash is still a good idea for markets, small businesses, or places where electronic payments may not be available.
Is Wise Right for Everyone?
Is Wise Right for Everyone?
No financial product is perfect for every traveller.
Wise may be particularly suitable if you:
Travel internationally more than once a year.
Visit multiple countries on one trip.
Shop online in foreign currencies.
Receive or send international payments.
Prefer managing your money from a mobile app.
If you're only travelling once and expect to use very little foreign currency, a traditional bank card may still meet your needs. Comparing fees and exchange rates before you travel is always worthwhile.
Suggested Travel Money Strategy
Suggested Travel Money Strategy
For most holidays, we recommend combining several payment methods rather than relying on just one.
A simple approach might look like this:
Primary payment: Wise Card for everyday spending.
Backup: Your regular debit or credit card.
Cash: A modest amount of local currency for transport, markets, and emergencies.
This gives you flexibility while reducing the risk of being left without access to funds if one payment method isn't available.
Tips for Getting the Best Exchange Rate
Tips for Getting the Best Exchange Rate
✔ Compare providers before converting money.
✔ Avoid exchanging money at airports whenever possible.
✔ Choose to pay in the local currency when using your card overseas. This helps avoid Dynamic Currency Conversion (DCC), where a merchant converts the transaction into your home currency at a less favourable rate.
✔ Monitor exchange rates if you're travelling several months in advance and convert funds gradually if appropriate.
✔ Always keep a second payment method in case your primary card is lost or unavailable.
Our Recommendation
Our Recommendation
If you travel internationally more than once a year, a Wise Account and Wise Card are well worth considering.
They provide a straightforward way to hold, convert, and spend multiple currencies while helping you avoid many of the hidden costs associated with traditional currency exchange.
