Multi-Currency Accounts for Travellers — What They Do, What They Cost, and When a Normal Bank Card Is Still Better
Wise, Revolut and similar accounts let you hold several currencies and spend at close to the mid-market rate. How they actually save money, the fees that still apply, and the situations where your ordinary bank card wins.
A multi-currency account is a bank-like account from a fintech that lets you hold balances in several currencies, convert between them at close to the mid-market rate, and spend or withdraw with a linked debit card. For anyone who travels more than once a year, or who is paid in one currency and lives in another, it is usually the single biggest money-saver available. It is not free, and it is not always the right tool.
What you are actually paying for
| Cost | Ordinary bank card | Multi-currency account |
|---|---|---|
| Exchange rate | Card network rate plus the bank's margin, often a few percent | Close to mid-market rate plus a small, visible conversion fee |
| Foreign transaction fee | Common, charged as a percentage of every purchase | Usually none when you spend from a balance you already hold |
| ATM withdrawals abroad | Fixed fee plus percentage, plus the local ATM's fee | A free allowance per month, then a percentage; the local ATM fee still applies |
| Receiving money in other currencies | Usually impossible, or expensive | Local account details in several currencies, so you can be paid like a local |
The savings come from the exchange rate and the absence of a foreign transaction fee. The cost that does not go away is the local ATM fee, which is charged by the machine's owner and applies to every foreign card regardless of who issued it.
How to use one well
- Convert before you spend, when the rate is good. Holding the destination currency means the card pays from that balance with no conversion at the checkout.
- Or let the card convert automatically. If you have no balance in the local currency, the account converts at the moment of purchase at its published fee. This is still far cheaper than most bank cards, and it saves you guessing how much you need.
- Decline dynamic currency conversion. Terminals and ATMs will offer to charge you in your home currency. Always choose the local currency; the account's rate is better than the terminal's. See how to avoid dynamic currency conversion everywhere.
- Use the ATM allowance for cash, not the card for everything. Many places in Southeast Asia are cash-first; take out larger amounts less often to spread the fixed fee.
Where a normal bank card is still better
- Purchases with strong protection. Credit cards from a bank carry chargeback rights and, in some countries, statutory protection on larger purchases. A prepaid or debit fintech card often carries less.
- Hotel and car-hire deposits. Some merchants hold large amounts on debit cards for weeks. A credit card takes the hold against your limit instead of your cash.
- Countries where the fintech is not licensed. Coverage is broad but not universal; check that the account can hold or convert to the currency you need.
- Emergencies. If the app locks you out, a second card from a different provider is the only fix. Never travel with one card.
Opening one
Most providers verify identity with a passport photo and a selfie, and issue a virtual card immediately with a physical card by post. Sign up from your home country before you leave: the address on the account should match your official documents, and some providers will not onboard you while you are abroad. If you are moving to Thailand, this is also the account to use for sending money to Thailand cheaply once you have a local bank account.
Common mistakes
- Treating it as the only account. It is a spending and conversion tool, not a place to keep savings; deposit protection is different from a bank.
- Converting large sums at the weekend. Providers add a weekend markup when markets are closed; convert on a weekday.
- Ignoring the free ATM allowance. After the allowance, the percentage fee makes many small withdrawals expensive.
Summary
A multi-currency account removes the exchange-rate margin and the foreign transaction fee that make ordinary bank cards expensive abroad. Keep a credit card from a bank alongside it for deposits and purchase protection, decline conversion at every terminal, and use the ATM allowance in larger, less frequent withdrawals.
