This applies to “Commercial Banks”within Thailand.
Note that “GSB”…. the Thai Gov’t Savings Bank is not a “Commercial Bank”.
If you keep more than 1MTB on deposit here in Thailand, it is in your best interest to protect your deposits in the event the bank fails. Open accounts with other banks and keep your balances at no more than 1MTB.
However, if you have Thai ID and a Yellow Book Tambian Baan, you are permitted to open an account with the “GSB”…. Government Savings Bank, which is not a “Commercial Bank.
If you plan on traveling around SE Asia….United Overseas Bank (UOB) have branch’s all through SE Asia.
Otherwise GSB. “Gov’t Savings Bank”. They have branches in every small village throughout Thailand, unlike many of the other more mainstream commercial banks.
I’ve been living in Phuket for over the past 26yrs and though I have accounts with other banks, UOB and GSB are my two primary banks.
