What amount do I need to show in cash at Bangkok airport if asked?

I was asked about 3 months ago. I showed the IO 300 GBP and 300 USD. They amount you need to show if they ask you, which is very rare, is the equivalent of 20,000 Thai Baht.

Cut your dreadlocks

Yes, about AUD 1,000. Not a great amount for a holiday. I know some don't like to carry a lot of cash on them, so maybe access to an ATM would work, but as you said, it's usually just a simple excuse to deny entry.

Bank is not sufficient. In cash in any currency only

If they ask, which is very rare, it's 20,000 baht cash and cash only.

Never been asked.

You drunk or what ? I have go out and in to thailand 2 times a year since 2004 never heard or been asking abouth that

Immigration rarely asks for it at all, but if asked you must show 20,000 baht in cash or the equivalent in foreign currency, not your bank account, credit cards etc, must be cash. But 99% of the time it is not even asked for.

The fact that many responders have not been asked is irrelevant to the fact that an individual entering on a tourism entry stamp can be asked to show the equivalent of 20,000B cash, that's the law.

I've been going for twice a year for 35 years and never been asked once

In over 20 yrs visiting LOS a minimum of 3 times a yr I have never been asked to show proof of cash. I think that would be a path the IO would go down if he was building a case for other reasons to refuse you entry. Same as a forwarding flight, never been asked for proof of that either.

I’ve never been asked in 25 years

20k might get you in but realistically you should stay home if that’s a struggle to prove.

I was asked once at the Rayong border in Myanmar. But I just pulled out my cash. And they didn't count it and were like eh ok fine.

Got be cash if asked

I always bring at least €600 in cash just in case, was asked years ago but it's very rare

No idea never been asked and I live here in and out frequently

IF asked to show amount (very few are asked) it would need to be 20,000 baht or equivalent in cash only. A bank account or credit card statement doesn’t suffice.

Cash amount is incredibly rarely asked for. The law exists that they can ask but they’ll only invoke the rule if they’re looking for a reason to deny you entry. For 99.9% of people that won’t happen.
