Is cash mandatory to enter Thailand, or can I provide a bank statement instead?

Never been asked for cash, but have been asked for address of where I was staying, and I've always showed them my return ticket .. so usually when they asked for my passport at immigration I usually handed then my passport with the return ticket and TM30 that you used to fill out on the plane before landing (I think they stopped doing that though so if I were coming in I'd write the address on a paper and include it.)

I've never been asked to prove what money I have on many trips to Thailand. Play it safe, take the cash required, and don't do what I once did in the Philippines. Took no cash, thinking I can get from atm at airport, but atm rejected my British bank card. BIG MISTAKE

Just bring 20,000 bahts worth of Pounds and change it when you get here,much better rates,just make sure the notes are brand new and in pristine condition otherwise they will be rejected at every money exchange and bank.

If I were you I’d bring cash anyway and change it here for a better rate ATM’s can get expensive and not the greatest rates

If you have any significant visa history over the last 12 months, as in, back-to-back tourist visas and/or visa-exempt entries, they might ask.

If this isnt the case, if this is your first time in TH, they likely won't.

Legally you would be asked to show, 20,000 baht cash or the equivalent in foreign currency, a bank statement or Visa card will not suffice. But in reality it is hardly asked for, just be aware they potentially could.

Just carry 500 quid in gbp that will cover the 20,000 ive never been asked in all the years ive been there plus i always take cadh never used a card cos they shaft you then ya own bank shafts you as well for the pleasure!!

Bring your cash. Why risk disaster?

You can spend it during your trip and save on ATM fees.

So technically your requirements are the 3 proofs:

20k baht or equivalent in foreign currency CASH

Proof of accommodation

Proof of travel out of Thailand in the period of your allowed entry.

Although very rare it does happen.

Chances are you will not be asked. I'd say 99.9% are not, but if you are, it's 20,000 baht in ANY currency. A bank statement will not suffice and there is no access to an ATM

I assume you are arriving with a tourist visa or with no visa (visa exempt) as those are the only times they could ask to see money.

It's very rare for them to ask. Usually they will only ask if they want to deny you entry to the country and want to find an easy reason to do so.

But if they do ask, it must be CASH ONLY. You cannot show them a bank statement, a banking app, a credit card, or anything except cash.

You do not need to convert money to Thai baht before you travel as the regulation is 20,000 baht OR equivalent in another major currency. So the same amount in dollars, euroes, pounds etc is fine.
