To get to the truth you must spit the transfer with wise into exchange and transfer.
Idk about your case, but I transfer my currency to wise without any fees.
Then I convert to THB (after waiting for a good exchange rate!).
Then I send THB to my this bank for 44.76 baht per transaction.
No to the conversion: Wise uses interbank rates which is lots better than all the banks. You can see that rate in their web page.
And you should find the bank’s “cash rate” on their homepage - which is better than the “exchange rate” used when transferring money.
You will probably see that you get 1.5-2.5 better rates from wise.
