3 year ago when I was a tourist I open a Thai baht account & GBP Foreign currency account. The idea being to transfer regular amounts from U.K. Bank to Thai bank in GBP to attain the necessary funds to meet any financial requirements set by immigration. There is a fee involved to send & receive money & alas the exchange rate has fallen.... but it was for a purpose. The money will remain untouched until the rate rises, so it could be there a long time but at least it serves to acquire a '12 month permission of stay'
