Good news and possibly bad news. It looks like accounts with wrong visa type may still be frozen or closed. Let's see the full outcome.
This below from Pattaya News
"The Bank of Thailand resolved in a meeting today with commercial banks that accounts frozen must be unblocked within four business hours if the holder provides proof they aren't tied to scammers. Additionally, only funds believed used or connected to scams should be frozen and not the entire account. However this may take until the end of the month to implement.
Additionally, this is only if the account is flagged or frozen for potential scams or ties to mule accounts, not if it is flagged for Know Your Customer violations like suspected incorrect visa for foreigners, sim card, or other incorrect information used to set up and register.
However, it's a start. Full article later."
TLDR : Answer Summary
Recent discussions indicate that bank accounts in Thailand, particularly those flagged for potential scams, must be unblocked within four business hours if proof of legitimacy is provided. However, accounts flagged for having incorrect visa types will remain frozen, affecting foreigners, including those on tourist visas. The broader implications of these regulations are causing concern across various sectors, with many retailers halting scan payments to avoid freezing of their accounts. There's also frustration about the practicality of maintaining a bank account in Thailand under these circumstances.
