I have just made a small transfer to the new Bangkok Bank account I opened this week...................that is also showing Monday 10:00 am for reeipt.
I can live with that.
Still cheaper to use WISE for those couple of occasions.
As your transfers are likely to be relatively large the difference in the exchange rate will make quite a difference.
98% of my transfers take under 10 seconds.
I transfer funds from my main UK bank account into my WISE account - and then remit money to Thailand from there.
