Curious about the best way/least penalties for a Thai national to withdraw a large amount of money from a Thai bank account to transfer to the U.S.

how much ?

how much ?

1,000,000 THB

Siam Commercial accounts can withdraw Bt200,000 a day per account (limit has to be raised at the ATM).

Bangkok Bank can do at least Bt150,000 and I have one or two which can do Bt500,000 per day.

Around the world, I have found Citibank ATMs can push out the most notes at one time. If you could get $1000 a time (Bt33,000 or so), then you could do it in very little time the money dispersed through a few Thai bank accounts.

You can send about Bt100,000 to each different bank account (e.g. BB to SCB) from the host account per day over the internet for about Bt30.

With SCB giving Bt200,000 a day, You'd need 5 days (6 most likely) using only one account or 1 day with 5 accounts.

Sending money overseas needs approval and form filling but can use SWIFT.
