i have checked both MBB and HSBC on Swift transfer method. For 400-500k Baht, such significant in terms of difference rates between banks and Wise. I can say plus minus about MYR2-3k more than Wise rate.
for all the while, i thought it has to come and flagged as international transfer. Then from wise, the reason could be any choice, not necessarily to choose as funds for long term stay in Thai. Am i right?
