So today I contacted Bangkok Bank in regards to opening an account with a DTV visa, I was told that there are no set rules and it’s all dependant on the specific bank manager in the branch that you try.
She also mentioned that even if one branch refuses to try another as there are DTV holders with bank accounts.
TLDR : Answer Summary
The issue of whether one can open a bank account in Thailand with a DTV visa is contentious and appears to depend heavily on individual bank branches and managers. Some individuals have reported success in opening accounts with DTV visas, but recent discussions suggest that rules may have become stricter. Several comments mention recent changes in policy, increased scrutiny due to anti-money laundering regulations, and general difficulty for DTV holders to access banking services. Key takeaway: while some have succeeded, experiences vary greatly, and persistence may be necessary.
