On the TransferWise topic that was closed. TransferWise now supports sending US dollars to USD denominated accounts in countries outside the US, including Thailand. The cost for this is quite low- $3.20, which is probably less than your bank charges. You could use this to send to a USD FCD account in Thailand. It goes through the SWIFT network so should appear as a regular international transfer whichever bank you use. I haven't tried it, but I suspect it MAY also work sending to a THB denominated account, in which case your Thai bank would automatically do the conversion on arrival, this is what happens with regular USD SWIFT transfers to a THB account.
