How a multicurrency account works

Most UK bank accounts hold only pounds. When you pay in baht, your card converts the amount back to pounds at that moment. A multicurrency account adds separate balances — "wallets" or "pockets" — for other currencies, so you can hold baht alongside pounds.

There are two main kinds. Multicurrency accounts such as Wise and Revolut are full-featured apps with a debit card, where you can hold dozens of currencies, convert any time and send money abroad. Prepaid travel money cards such as the Post Office and Travelex cards are simpler: you load currency onto the card before you travel and spend it while you're away.

The difference that matters most is the exchange rate. Multicurrency accounts generally convert at or very close to the mid-market rate — the "real" rate you see on Google — plus a small, visible fee. Prepaid travel cards set their own rate, and the margin built into it is where most of the cost lies, even when the card advertises no fees.

Which UK accounts can hold Thai baht?

Not every account that calls itself "multicurrency" supports baht, and some of the best fee-free UK bank cards don't hold foreign currency at all. This is where things stood in October 2026:

"Safeguarded" means the provider must keep your money separate from its own, so it should be returned to you if the firm fails — but it isn't covered by the Financial Services Compensation Scheme in the way a UK bank deposit is. For holiday money that's rarely a concern. For larger sums held for months, it's worth keeping in mind.

The UK bank cards that don't hold baht — Chase, Starling, Monzo and Kroo — are still excellent in Thailand because they charge no fee for spending abroad and convert at the network rate. Holding baht is a choice about controlling your rate, not a requirement for avoiding fees.

The best multicurrency accounts and cards for Thailand

Four ways to hold Thai baht from the UK, ranked on exchange rate, fees and how useful they are in Thailand.

If you only want one account, Wise is the most useful for Thailand: the best rate for holding baht, and the cheapest way to send money to a Thai bank account later. Revolut is the better app for day-to-day budgeting, as long as you convert on weekdays. The prepaid cards are best for people who specifically want their holiday money separate from their bank.

What £1,000 actually buys

Headline fees tell you little. What matters is how many baht you end up with. These are the rates we were offered on 11–12 October 2026 for converting £1,000, against a mid-market rate of ฿44.27:

The gap between the best and worst options here is around ฿3,400 — enough for several nights in a decent guesthouse or a week of street food. Notice how much worse the Post Office rate is for smaller amounts: its online rate improves at £500 and again at £1,000. Branch rates and travel money card rates can differ again.

Rates move every day, so treat these as a snapshot. The pattern, though, is consistent: multicurrency accounts and specialist transfer services convert close to mid-market, and prepaid travel cards and high-street bureaux build a margin of several per cent into their rate.

Should you lock in a rate before you fly?

The main reason to hold baht is to fix your exchange rate in advance. Whether that's a good idea depends on what happens to the pound before and during your trip — which nobody can predict reliably.

A sensible middle way is to convert part of your budget in advance and leave the rest in pounds. Both Wise and Revolut let you set rate alerts, so you can convert when the pound reaches a level you're happy with. If you use Revolut, convert on a weekday to avoid the weekend fee.

Sending money from the UK to Thailand

If you live in Thailand, support family there, pay rent or school fees, or need to fund a visa deposit, you'll need to move money from the UK to a Thai bank account. This is where multicurrency accounts and specialist transfer services save the most money.

A traditional UK bank transfer to Thailand usually goes over the SWIFT network. You may pay a fee to your UK bank, a margin on the exchange rate, and charges from intermediary banks and the receiving Thai bank. The total is rarely shown up front.

Specialist providers are usually far cheaper and much clearer about the cost:

Always compare the amount the recipient will receive in baht, not just the fee. Get quotes from two or three providers on the same day for the same amount — the cheapest option can change with the size of the transfer.

For very large transfers — buying a condo, funding a retirement visa deposit of ฿800,000 or moving a pension pot — the exchange rate on a single day can make a difference of thousands of pounds. That's when it pays to plan the timing and structure properly.

Using a multicurrency card in Thailand

Once you're in Thailand, a multicurrency card works like any other Visa or Mastercard. A few things are worth knowing:

• Spending held baht is free on Wise, Revolut and both prepaid cards.
• If your baht runs out, Wise and Revolut convert from pounds automatically. Prepaid cards may charge a fee or decline.
• Thai ATMs still charge ฿220 on every withdrawal with a foreign card, whatever you hold.
• Always decline conversion at ATMs and card machines, so you're charged in baht.
• Thai QR payments generally need a Thai bank app — multicurrency cards can't pay them.
• Carry a second card from a different provider in case one is blocked.

Holding baht doesn't change the ฿220 Thai ATM fee, so the advice for cash is the same as for any card: withdraw larger amounts less often, and look for AEON machines, which have been widely reported at ฿150. Our guide to the best cards for Thai ATM withdrawals has the full detail.

Keep your money apps working abroad

A multicurrency account lives in an app, so it's only as useful as your phone's connection. Two things catch British travellers out in Thailand:

Security codes sent by text. Some UK banks and card providers still send one-time passcodes by SMS to confirm payments or log-ins. If your UK number isn't working abroad — or you've let it lapse — you can find yourself locked out of your own account. Keep a UK SIM active, or switch to app-based verification before you travel. A cheap SIM-only plan is an easy way to keep a UK number.

Public Wi-Fi. Hotel, café and airport Wi-Fi is convenient, but you don't know who else is on the network. Banking apps use their own encryption, but a reputable VPN adds a further layer of protection when you're on public networks. If a banking app refuses to work over a VPN, switch it off and use mobile data instead.
